SearchSuite provides further control over Wikipedia search results, such as on/off features to sort them, to present results one-per-line, and more. While it seems to work fairly well, there is definitely room for improvement. Comments and suggestions are welcome.
By the way, most of the scripts I've been working on are for building and augmenting outlines...
I'm interested in all knowledge, especially how to organize it so you can find whatever is most relevant at any given moment.
I've been around Wikipedia since the Fall of 2005, and have been working mostly on Wikipedia's structure, and its knowledge navigation systems, throughout that time.
Visualization of various methodological approaches to gaining insights from meta data areas
Information science is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.

An abdominous obese male Weight: 182 kg/400 lbs Height: 185 cm/6 ft 1 in Body mass index: 53
Visceral fat, also known as organ fat or intra-abdominal fat, is located inside the peritoneal cavity, packed in between internal organs and torso, as opposed to subcutaneous fat, which is found underneath the skin, and intramuscular fat, which is found interspersed in skeletal muscle. Visceral fat is composed of several adipose depots including mesenteric, epididymal white adipose tissue (EWAT), and perirenal fat. An excess of adipose visceral fat is known as central obesity, the "pot belly" or "beer belly" effect, in which the abdomen protrudes excessively. This body type is also known as "apple shaped", as opposed to "pear shaped" in which fat is deposited on the hips and buttocks.
Researchers first started to focus on abdominal obesity in the 1980s when they realized it had an important connection to cardiovascular disease, diabetes, and dyslipidemia. Abdominal obesity was more closely related with metabolic dysfunctions connected with cardiovascular disease than was general obesity. In the late 1980s and early 1990s insightful and powerful imaging techniques were discovered that would further help advance the understanding of the health risks associated with body fat accumulation. Techniques such as computed tomography and magnetic resonance imaging made it possible to categorize mass of adipose tissue located at the abdominal level into intra-abdominal fat and subcutaneous fat.

A userscript manager, also known as a userscript engine, is a type of browser extension and augmented browsing technology that provides a user interface to run and organize userscripts. The main purpose of a userscript manager is to execute scripts on predetermined webpages as they are loaded, for example, running a userscript to modify only youtube.com pages. But, userscript managers do a lot more than execute scripts, and screen for the pages they are intended to run on. The most common operations performed by a userscript manager include installing, organizing, creating, copying, saving, deleting, and editing (including modifying webpage permissions of) userscripts.
Userscript managers use metadata that is embedded in a script's source code primarily to determine the websites it should execute on and the dependencies necessary for the script to run properly. Metadata can also include information that is useful to the user such as the script's name, author, description and version number.
A revenue model is a framework for generating financial income. There can be a variety of ways for revenue generation such as the production model, manufacturing model, as well as the construction model. A revenue model identifies which revenue source to pursue, what value to offer, how to price the value, and whopays for the value. It is a key component of a company's business model. A revenue model primarily identifies what product or service will be created and sold in order to generate revenues.
Without a clear and well-defined revenue model new businesses will be more likely to struggle. By having a clear revenue model, a business can focus on a target audience, fund development plans for a product or service, establish marketing plans, open a line of credit and raise capital.

After the Portolá expedition of 1769–1770, Spanish missionaries began setting up 21 California missions on or near the coast of Alta (Upper) California, beginning with the Mission San Diego de Alcala near the location of the modern day city of San Diego, California. During the same period, Spanish military forces built several forts (presidios) and three small towns (pueblos). Two of the pueblos would eventually grow into the cities of Los Angeles and San Jose. After Mexico's Independence was won in 1821, California fell under the jurisdiction of the First Mexican Empire. Fearing the influence of the Roman Catholic church over their newly independent nation, the Mexican government "secularized" all of the missions. The missions were closed down in 1834; their priests mostly returned to Mexico. The churches ended religious services and fell into disrepair. The mission farmlands were seized by the government and handed out as grants to favorites. They left behind a "Californio" population of several thousand families, with a few small military garrisons. After losing the Mexican–American War of 1846–1848, the Mexican Republic was forced to relinquish any claim to California to the United States.
The California Gold Rush of 1848–1855 attracted hundreds of thousands of ambitious young people from around the world to Northern California. Only a few struck it rich, and many returned home disappointed. Most appreciated the other economic opportunities in California, especially in agriculture, and brought their families to join them. California became the 31st U.S. state in the Compromise of 1850 and played a small role in the American Civil War. Chinese immigrants increasingly came under attack from nativists; they were forced out of industry and agriculture and into Chinatowns in the larger cities. As gold petered out, California increasingly became a highly productive agricultural society. The coming of the railroads in 1869 linked its rich economy with the rest of the nation, and attracted a steady stream of settlers. In the late 19th century, Southern California, especially Los Angeles, started to grow rapidly. (Full article...)

Knowledge extraction is the creation of knowledge from structured (relational databases, XML) and unstructured (text, documents, images) sources. The resulting knowledge needs to be in a machine-readable and machine-interpretable format and must represent knowledge in a manner that facilitates inferencing. Although it is methodically similar to information extraction (NLP) and ETL (data warehouse), the main criterion is that the extraction result goes beyond the creation of structured information or the transformation into a relational schema. It requires either the reuse of existing formal knowledge (reusing identifiers or ontologies) or the generation of a schema based on the source data.
Athlete's foot, known medically as tinea pedis, is a common skin infection of the feet caused by a fungus. Signs and symptoms often include itching, scaling, cracking and redness. In rare cases the skin may blister. Athlete's foot fungus may infect any part of the foot, but most often grows between the toes. The next most common area is the bottom of the foot. The same fungus may also affect the nails or the hands. It is a member of the group of diseases known as tinea.
Athlete's foot is caused by a number of different funguses, including species of Trichophyton, Epidermophyton, and Microsporum. The condition is typically acquired by coming into contact with infected skin, or fungus in the environment. Common places where the funguses can survive are around swimming pools and in locker rooms. They may also be spread from other animals. Usually diagnosis is made based on signs and symptoms; however, it can be confirmed either by culture or seeing hyphae using a microscope.
Athlete's foot is not limited to just athletes: it can be caused by going barefoot in public showers, letting toenails grow too long, wearing shoes that are too tight, or not changing socks daily. It can be treated with topical antifungal medications such as clotrimazole or, for persistent infections, using oral antifungal medications such as terbinafine. Topical creams are typically recommended to be used for four weeks. Keeping infected feet dry and wearing sandals also assists with treatment.
Athlete's foot was first medically described in 1908. Globally, athlete's foot affects about 15% of the population. Males are more often affected than females. It occurs most frequently in older children or younger adults. Historically it is believed to have been a rare condition that became more frequent in the 20th century due to the greater use of shoes, health clubs, war, and travel. (Full article...)

Location of Asia Asian cuisine encompasses several significant regional cooking styles of Asia: Central Asian, East Asian, North Asian, South Asian, Southeast Asian, and West Asian. Cuisine is a distinctive way of cooking practices and customs, usually associated with a specific culture. Asia, as the largest and most populous continent, is home to many cultures, each with its own characteristic cuisine. Asian cuisine, also known as Eastern cuisine, is considered the "culture of food within a society" due to the beliefs, cooking methods, and the specific ingredients used throughout the entire process. Asian cuisines are also renowned for their spices. A key taste factor in Asian cuisine is “umami” flavor, a strong savoriness prominent in Asian cooking, which can be achieved through fermented food or meat extract.
Ingredients common to many cultures in East and Southeast Asia include rice, ginger, garlic, sesame seeds, chilis, dried onions, soy, and tofu. Stir frying, steaming, and deep frying are common cooking methods.
While rice is common to most Asian cuisines, different varieties are popular in the various regions. Glutinous rice is ingrained in the culture, religious tradition and national identity of Laos. Basmati rice is popular in the Indian subcontinent, jasmine rice is often found across Southeast Asia, while long-grain rice is popular in China and short-grain in Japan and Korea.
Curry is a common dish in South Asia, Southeast Asia, and East Asia. Curry dishes have their origins in the Indian subcontinent. Countries in Indochina typically use a coconut milk base in their curries; countries in Southwest Asia typically use a yogurt base. (Full article...)
A plot showing the length of software engineering tasks achievable by leading AI models with a 50% success rate; the data suggests an exponential rise. Existential risk from artificial intelligence refers to the idea that substantial progress in artificial general intelligence (AGI) could lead to human extinction or an irreversible global catastrophe. One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by researchers including Geoffrey Hinton, Yoshua Bengio, Demis Hassabis, and Alan Turing, and AI company CEOs such as Dario Amodei (Anthropic), Sam Altman (OpenAI), and Elon Musk (xAI). In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.
Two sources of concern stem from the problems of AI control and alignment. Controlling a superintelligent machine or instilling it with human-compatible values may be difficult. Many researchers believe that a superintelligent machine would likely resist attempts to disable it or change its goals as that would prevent it from accomplishing its present goals. It would be extremely challenging to align a superintelligence with the full breadth of significant human values and constraints. In contrast, skeptics such as computer scientistYann LeCun argue that superintelligent machines will have no desire for self-preservation. (Full article...)

Life extension is the concept of extending the human lifespan, either modestly through improvements in medicine or dramatically by increasing the maximum lifespan beyond its generally-settled biological limit of around 125 years. Several researchers in the area, along with "life extensionists", "immortalists", or "longevists" (those who wish to achieve longer lives themselves), postulate that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans through complete rejuvenation to a healthy youthful condition (agerasia). The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.
The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that promotes the use of hormones as a treatment for consumers to slow or reverse the aging process in the US market generated about $50 billion of revenue a year in 2009. The use of such hormone products has not been proven to be effective or safe. Similarly, a variety of apps make claims to assist in extending the life of their users, or predicting their lifespans.

Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include old technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo.
Emerging technologies are characterized by radical novelty (in application even if not in origins), relatively fast growth, coherence, prominent impact, and uncertainty and ambiguity. In other words, an emerging technology can be defined as "a radically novel and relatively fast growing technology characterised by a certain degree of coherence persisting over time and with the potential to exert a considerable impact on the socio-economic domain(s) which is observed in terms of the composition of actors, institutions and patterns of interactions among those, along with the associated knowledge production processes. Its most prominent impact, however, lies in the future and so in the emergence phase is still somewhat uncertain and ambiguous."
New technological fields may result from the technological convergence of different systems evolving towards similar goals. Convergence brings previously separate technologies such as voice (and telephony features), data (and productivity applications) and video together so that they share resources and interact with each other, creating new efficiencies.

Friendly artificial intelligence (friendly AI or FAI) is hypothetical artificial general intelligence (AGI) that would have a positive (benign) effect on humanity or at least align with human interests such as fostering the improvement of the human species. It is a part of the ethics of artificial intelligence and is closely related to machine ethics. While machine ethics is concerned with how an artificially intelligent agent should behave, friendly artificial intelligence research is focused on how to practically bring about this behavior and ensuring it is adequately constrained.

Scraping a web page involves fetching it and then extracting data from it. Fetching is the downloading of a page (which a browser does when a user views a page). Therefore, web crawling is a main component of web scraping, to fetch pages for later processing. Having fetched, extraction can take place. The content of a page may be parsed, searched and reformatted, and its data copied into a spreadsheet or loaded into a database. Web scrapers typically take something out of a page, to make use of it for another purpose somewhere else. An example would be finding and copying names and telephone numbers, companies and their URLs, or e-mail addresses to a list (contact scraping).
Web pages are built using text-based mark-up languages (HTML and XHTML), and frequently contain a wealth of useful data in text form. However, most web pages are designed for human end-users and not for ease of automated use. As a result, specialized tools and software have been developed to facilitate the scraping of web pages. Web scraping applications include market research, price comparison, content monitoring, and more. Businesses rely on web scraping services to efficiently gather and utilize this data.

Natural science or empirical science is a branch of science concerned with the description, understanding, and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and reproducibility of findings are used to try to ensure the validity of scientific advances.
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology. Physical science is subdivided into physics, astronomy, Earth science, and chemistry. These branches of natural science may be further divided into more specialized branches, also known as fields. As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements that can be explained as clear statements of the "laws of nature".
A block is a defensive tactic in chess in response to an attack, consisting of interposing a piece between the opponent's attacking piece and the piece being attacked. This type of blocking will only work if the attacking piece is a type that can move linearly an indefinite number of squares such as a queen, rook, or bishop and there is at least one empty square in the line between the attacking and attacked piece. Blocking is not an option when the attacking piece is directly adjacent to the piece it is attacking, or when the attacking piece is a knight (because knights "jump over other pieces" and cannot be blocked). When an opponent's attack on a piece is blocked, the blocking piece is to some extent pinned, either relatively or absolutely, until a future move by either side allows it to be unpinned.
A check on a king by an opponent's queen, rook, or bishop can sometimes be blocked by moving a piece to a square in line in between the opponent's checking piece and the checked king. The blocking piece is then absolutely pinned to the king by the attacking piece.
Another type of interposing in chess can involve placing a piece between two opponent's pieces where one of those pieces is protecting the other, or they are both protecting each other. This chess tactic can be called interference. (Full article...)

Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities.
Since 1804, the global living human population has increased from 1 billion to 8 billion due to medical advancements and improved agricultural productivity. Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. According to the most recent United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide. Other models agree that the population will stabilize before or after 2100. Conversely, some researchers analyzing national birth registries data from 2022 and 2023—which cover half the world's population—argue that the 2022 UN projections overestimated fertility rates by 10 to 20% and were already outdated by 2024. They suggest that the global fertility rate may have already fallen below the sub-replacement fertility level for the first time in human history and that the global population will peak at approximately 9.5 billion by 2061. The 2024 UN projections report estimated that world population would peak at 10.29 billion in 2084 and decline to 10.18 billion by 2100, which was 6% lower than the UN had estimated in 2014.
LCC has been criticized for lacking a sound theoretical basis; many of the classification decisions were driven by the practical needs of that library rather than epistemological considerations. Although it divides subjects into broad categories, it is essentially enumerative in nature. That is, it provides a guide to the books actually in one library's collections, not a classification of the world. (Full article...)

The meaning of life is the concept of an individual's life, or existence in general, having an inherent significance or a philosophical point. There is no consensus on the specifics of such a concept or whether the concept itself even exists in any objective sense. Thinking and discourse on the topic is sought in the English language through questions such as—but not limited to—"What is the meaning of life?", "What is the purpose of existence?", and "Why are wehere?". There have been many proposed answers to these questions from many different cultural and ideological backgrounds. The search for life's meaning has produced much philosophical, scientific, theological, and metaphysical speculation throughout history. Different people and cultures believe different things for the answer to this question. Opinions vary on the usefulness of using time and resources in the pursuit of an answer. Excessive pondering can be indicative of, or lead to, an existential crisis.
Genius is a characteristic of original and exceptional insight in the performance of some art or endeavor that surpasses expectations, sets new standards for the future, establishes better methods of operation, or remains outside the capabilities of competitors. Genius is associated with intellectual ability and creative productivity. The term genius can also be used to refer to people characterised by genius, and/or to polymaths who excel across many subjects.
There is no scientifically precise definition of genius. When used to refer to the characteristic, genius is associated with talent, but several authors such as Cesare Lombroso and Arthur Schopenhauer systematically distinguish these terms. Walter Isaacson, biographer of many well-known geniuses, explains that although high intelligence may be a prerequisite, the most common trait that actually defines a genius may be the extraordinary ability to apply creativity and imaginative thinking to almost any situation.
In the early-19th century Carl von Clausewitz, who had a particular interest in what he called "military genius", defined "the essence of Genius" (German: der Genius) in terms of "a very high mental capacity for certain employments". (Full article...)

Health has a variety of definitions, which have been used for different purposes over time. In general, it refers to physical and emotional well-being, especially that associated with normal functioning of the human body, absent of disease, pain (including mental pain), or injury.
Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. (Full article...)
A taxonomy (or taxonomical classification) is a scheme of classification, especially, a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are.
Manually developing and maintaining a taxonomy is a labor-intensive task requiring significant time and resources, including familiarity of or expertise in the taxonomy's domain (scope, subject, or field), which drives the costs and limits the scope of such projects. Also, domain modelers have their own points of view which inevitably, even if unintentionally, work their way into the taxonomy. ATC uses artificial intelligence techniques to quickly automatically generate a taxonomy for a domain in order to avoid these problems and remove limitations. (Full article...)

Moore's law is an example of futurology; it is a statistical collection of past and present trends with the goal of accurately extrapolating future trends. Futures studies, futures research or futurology is the systematic, interdisciplinary and holistic study of social and technological advancement, and other environmental trends, often for the purpose of exploring how people will live and work in the future. Predictive techniques, such as forecasting, can be applied, but contemporary futures studies scholars emphasize the importance of systematically exploring alternatives. In general, it can be considered as a branch of the social sciences and an extension to the field of history. Futures studies (colloquially called "futures" by many of the field's practitioners) seeks to understand what is likely to continue and what could plausibly change. Part of the discipline thus seeks a systematic and pattern-based understanding of past and present, and to explore the possibility of future events and trends.
Unlike the physical sciences where a narrower, more specified system is studied, futurology concerns a much bigger and more complex world system. The methodology and knowledge are much less proven than in natural science and social sciences like sociology and economics. There is a debate as to whether this discipline is an art or science, and it is sometimes described as pseudoscience; nevertheless, the Association of Professional Futurists was formed in 2002, developing a Foresight Competency Model in 2017, and it is now possible to study it academically, for example at the FU Berlin in their master's course. To encourage inclusive and cross-disciplinary discussions about futures studies, UNESCO declared December 2 as World Futures Day. (Full article...)

To travel between stars within a reasonable amount of time (decades or centuries), an interstellar spacecraft must reach a significant fraction of the speed of light, requiring enormous amounts of energy. Communication with such interstellar craft will experience years of delay due to the speed of light. Collisions with cosmic dust and gas at such speeds can be catastrophic for such spacecrafts. Crewed interstellar travel could possibly be conducted more slowly (far beyond the scale of a human lifetime) by making a generation ship. Hypothetical interstellar propulsion systems include nuclear pulse propulsion, fission-fragment rocket, fusion rocket, beamed solar sail, and antimatter rocket. (Full article...)

A remaining section of the Aérotrain track near Saran 2006
The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917–1975) – and intended to bring the French rail network to the cutting edge of land-based public transportation.
Though similar to a maglev design, which levitates a train car over a complex electromagnetic track to eliminate all resistance other than aerodynamic drag, the Aérotrain – also a "train without wheels" – rode on an air cushion over a simple reinforced concrete track or guideway and could travel at the speed of a maglev train, without the further technical complexity and expense of its track. In many respects, the entire concept resembled a product of the aircraft rather than rail industry. (Full article...)

FJG diagrams FJG RAM, short for Floating Junction Gate Random Access Memory, is a type of computer memory invented and subsequently patented in July 2009 by Oriental Semiconductor Electronics, Ltd.
According to Oriental Semiconductor researchers, the FJG ram has an ultra-compact cell area of 4-5F2 (F refers to feature size) and a capacitor-less cell configuration. The FJG RAM can be produced in existing standard dynamic RAMfabrication plants. Due to the absence of a capacitor, the FJG cell process is more compatible with logic processes, allowing its use in standalone DRAM applications as well as embedded-DRAM applications. Other properties include non-destructive-read and the possibility for DRAM designers to use shared sense amplifiers to reduce the complexity of peripheral circuits. (Full article...)

A model of a space fountain
A space fountain is a proposed form of an extremely tall tower extending into space. As known materials cannot support a static tower with this height, a space fountain has to be an active structure: A stream of pellets is accelerated upwards from a ground station. At the top it is deflected downwards. The necessary force for this deflection supports the station at the top and payloads going up the structure. A spacecraft could launch from the top without having to deal with the atmosphere. This could reduce the cost of placing payloads into orbit. Its largest downside is that the tower will re-enter the atmosphere if the accelerator fails and the stream stops. This risk could be reduced by several redundant streams.
The lower part of a pellet stream has to be in a vacuum tube to avoid excessive drag in the atmosphere. Similar to the top station, this tube can be supported by its own system of transferring momentum from a space-bound stream to a surface-bound stream. If the tube itself also accelerates the station-supporting stream, it would have to transfer additional momentum to an earth-bound stream in order to keep itself supported. The tube-supporting streams could also be designed to integrate with the station-supporting streams. (Full article...)
A primary thesis of hedonism is that "pleasure is the good", which leads to the argument that any component of life that is not pleasurable does nothing directly to increase one's well-being. This is a view held by many value theorists, but most famously by some classical utilitarians. Nozick attacks the thesis by means of a thought experiment. If he can show that there is something other than pleasure that has value and thereby increases well-being, then hedonism is refuted. (Full article...)

The design requires fusion power technology beyond current capabilities, and much larger and more complex rockets.
Control theory is a field of control engineering and applied mathematics that deals with the control of dynamical systems. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, while minimizing any delay, overshoot, or steady-state error and ensuring a level of control stability; often with the aim to achieve a degree of optimality.
To do this, a controller with the requisite corrective behavior is required. This controller monitors the controlled process variable (PV), and compares it with the reference or set point (SP). The difference between actual and desired value of the process variable, called the error signal, or SP-PV error, is applied as feedback to generate a control action to bring the controlled process variable to the same value as the set point. Other aspects which are also studied are controllability and observability. Control theory is used in control system engineering to design automation that have revolutionized manufacturing, aircraft, communications and other industries, and created new fields such as robotics.

Magnonics is an emerging field of modern magnetism, which can be considered a sub-field of modern solid state physics. Magnonics combines the study of waves and magnetism. Its main aim is to investigate the behaviour of spin waves in nano-structure elements. In essence, spin waves are a propagating re-ordering of the magnetisation in a material and arise from the precession of magnetic moments. Magnetic moments arise from the orbital and spin moments of the electron, most often it is this spin moment that contributes to the net magnetic moment.
Following the success of the modern hard disk, there is much current interest in future magnetic data storage and using spin waves for things such as 'magnonic' logic and data storage. Similarly, spintronics looks to utilize the inherent spin degree of freedom to complement the already successful charge property of the electron used in contemporary electronics. Modern magnetism is concerned with furthering the understanding of the behaviour of the magnetisation on very small (sub-micrometre) length scales and very fast (sub-nanosecond) timescales and how this can be applied to improving existing or generating new technologies and computing concepts. A magnon torque device was invented and later perfected at the National University of Singapore's Electrical & Computer Engineering department, which is based on such potential uses, with results published on November 29, 2019, in Science.

The Advanced Tactical Laser (ATL) program was a US military program to mount a high energy laser weapon on an aircraft, initially the AC-130gunship, for use against ground targets in urban or other areas where minimizing collateral damage is important. The laser was a 100 kilowatt-class chemical oxygen iodine laser (COIL). It was expected to have a tactical range of approximately twenty kilometres and weigh about 5,000–7,000 kg. This program is distinct from the Airborne Laser, which was a much larger system designed to destroy enemy missiles in the boost phase. (Full article...)
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the flywheel.
Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.[why?] (Full article...)

Schematic of a magnetorheological fluid solidifying and blocking a pipe in response to an external magnetic field. (Animated version available.) A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid which, when subjected to a magnetic field, greatly increases in apparent viscosity, to the point of becoming a viscoelastic solid. Importantly, the yield stress of the fluid when in its active ("on") state can be controlled very accurately by varying the magnetic field intensity. The upshot is that the fluid's ability to transmit force can be controlled with an electromagnet, which gives rise to its many possible control-based applications.
MR fluid is different from a ferrofluid which has smaller particles. MR fluid particles are primarily on the micrometre-scale and are too dense for Brownian motion to keep them suspended (in the lower density carrier fluid). Ferrofluid particles are primarily nanoparticles that are suspended by Brownian motion and generally will not settle under normal conditions. As a result, these two fluids have very different applications. (Full article...)

A payment is the tender of something of value, such as money or its equivalent, by one party (such as a person or company) to another in exchange for goods or services provided by them, or to fulfill a legal obligation or philanthropy desire. The party making the payment is commonly called the payer, while the payee is the party receiving the payment. Whilst payments are often made voluntarily, some payments are compulsory, such as payment of a fine.
Payments can be effected in a number of ways, for example:
Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. Some common choices of structures to house vertical farming systems include buildings, shipping containers, underground tunnels, and abandoned mine shafts.
The modern concept of vertical farming was proposed in 1999 by Dickson Despommier, professor of Public and Environmental Health at Columbia University. Despommier and his students came up with a design of a skyscraper farm that could feed 50,000 people. Although the design has not yet been built, it successfully popularized the idea of vertical farming. Current applications of vertical farming coupled with other state-of-the-art technologies, such as specialized LED lights, have resulted in over 10 times the crop yield as would be received through traditional farming methods. There have been several different means of implementing vertical farming systems into communities such as: Canada (London),UK (Paignton), Israel, Singapore,USA (Chicago),Germany (Munich), UK (London), Japan, and UK (Lincolnshir)e.

Inspecting an AN/ALQ-184 Electronic Attack Pod.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceiveradar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances, so the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes blip enhancement and jamming missile terminal homers. (Full article...)

A scaled down model of Brahmos-II at Aero India 2013
The planned operational range of the BrahMos-II had initially been restricted to 290 kilometres as Russia is a signatory to the Missile Technology Control Regime (MTCR), which prohibits it from helping other countries develop missiles with ranges above 300 kilometres (190 mi; 160 nmi). However, subsequent to India becoming a MTCR signatory in 2014, the parameters for Brahmos 2 will get enhanced. Its top speed will be double that of the current BrahMos-I, and it has been described as the fastest cruise missile in the world. (Full article...)

Leica camera (1950s) A camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
Cameras function through a combination of multiple mechanical components and principles. These include exposure control, which regulates the amount of light reaching the sensor or film; the lens, which focuses the light; the viewfinder, which allows the user to preview the scene; and the film or sensor, which captures the image.

Participant in a brain-computer interface is getting connected to a computer A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (e.g. hands or feet). BCI implementations range from non-invasive (EEG, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how physically close electrodes are to brain tissue.
A smartwatch Wearable technology is any technology that is designed to be used while worn. Common types of wearable technology include smartwatches, fitness trackers, and smartglasses. Wearable electronic devices are often close to or on the surface of the skin, where they detect, analyze, and transmit information such as vital signs, and/or ambient data and which allow in some cases immediate biofeedback to the wearer. Wearable devices collect vast amounts of data from users making use of different behavioral and physiological sensors, which monitor their health status and activity levels. Wrist-worn devices include smartwatches with a touchscreen display, while wristbands are mainly used for fitness tracking but do not contain a touchscreen display.
Wearable devices such as activity trackers are an example of the Internet of things, since "things" such as electronics, software, sensors, and connectivity are effectors that enable objects to exchange data (including data quality) through the internet with a manufacturer, operator, and/or other connected devices, without requiring human intervention. Wearable technology offers a wide range of possible uses, from communication and entertainment to improving health and fitness, however, there are worries about privacy and security because wearable devices have the ability to collect personal data.

Millipede memory is a form of non-volatile computer memory. It promised a data density of more than 1 terabit per square inch (1 gigabit per square millimeter), which is about the limit of the perpendicular recordinghard drives. Millipede storage technology was pursued as a potential replacement for magnetic recording in hard drives and a means of reducing the physical size of the technology to that of flash media.
IBM demonstrated a prototype millipede storage device at CeBIT 2005, and was trying to make the technology commercially available by the end of 2007. However, because of concurrent advances in competing storage technologies, no commercial product has been made available since then. (Full article...)

An mRNAvaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine delivers molecules of antigen-encoding mRNA into cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer cell. These protein molecules stimulate an adaptive immune response that teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles that protect the RNA strands and help their absorption into the cells. Reactogenicity, the tendency of a vaccine to produce adverse reactions, is similar to that of conventional non-RNA vaccines. People susceptible to an autoimmune response may have an adverse reaction to messenger RNA vaccines. The advantages of mRNA vaccines over traditional vaccines are ease of design, speed and lower cost of production, the induction of both cellular and humoral immunity, and lack of interaction with the genomic DNA. While some messenger RNA vaccines, such as the Pfizer–BioNTech COVID-19 vaccine, have the disadvantage of requiring ultracold storage before distribution, other mRNA vaccines, such as the Moderna vaccine, do not have such requirements.

Solid waste after being shredded to a uniform size Waste are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
A typical suburban development in the United States, located in Chandler, Arizona
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.
In Europe, the term peri-urbanisation is often used to denote similar dynamics and phenomena, but the term urban sprawl is currently being used by the European Environment Agency. There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl by residential density, using the average residential units per acre in a given area. Others associate it with decentralization (spread of population without a well-defined centre), discontinuity (leapfrogging development, as defined below), segregation of uses, and so forth.
The term urban sprawl is highly politicized and almost always has negative connotations. It is criticized for causing environmental degradation, intensifying segregation, and undermining the vitality of existing urban areas, and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such. The term has become a rallying cry for managing urban growth. (Full article...)

Summary of major environmental-change categories that cause biodiversity loss. The data is expressed as a percentage of human-driven change (in red) relative to baseline (blue), as of 2021. Red indicates the percentage of the category that is damaged, lost, or otherwise affected, whereas blue indicates the percentage that is intact, remaining, or otherwise unaffected. Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species and climate change.
Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services, say that the main reason for biodiversity loss is a growing human population because this leads to human overpopulation and excessive consumption. Others disagree, saying that loss of habitat is caused mainly by "the growth of commodities for export" and that population has very little to do with overall consumption. More important are wealth disparities between and within countries. In any case, all contemporary biodiversity loss has been attributed to human activities.
Climate change is another threat to global biodiversity. For example, coral reefs—which are biodiversity hotspots—will be lost by the year 2100 if global warming continues at the current rate. Still, it is the general habitat destruction (often for expansion of agriculture), not climate change, that is currently the bigger driver of biodiversity loss. Invasive species and other disturbances have become more common in forests in the last several decades. These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. (Full article...)
A plot showing the length of software engineering tasks achievable by leading AI models with a 50% success rate; the data suggests an exponential rise. Existential risk from artificial intelligence refers to the idea that substantial progress in artificial general intelligence (AGI) could lead to human extinction or an irreversible global catastrophe. One argument for the importance of this risk references how human beings dominate other species because the human brain possesses distinctive capabilities other animals lack. If AI were to surpass human intelligence and become superintelligent, it might become uncontrollable. Just as the fate of the mountain gorilla depends on human goodwill, the fate of humanity could depend on the actions of a future machine superintelligence.
The plausibility of existential catastrophe due to AI is widely debated. It hinges in part on whether AGI or superintelligence are achievable, the speed at which dangerous capabilities and behaviors emerge, and whether practical scenarios for AI takeovers exist. Concerns about superintelligence have been voiced by researchers including Geoffrey Hinton, Yoshua Bengio, Demis Hassabis, and Alan Turing, and AI company CEOs such as Dario Amodei (Anthropic), Sam Altman (OpenAI), and Elon Musk (xAI). In 2022, a survey of AI researchers with a 17% response rate found that the majority believed there is a 10 percent or greater chance that human inability to control AI will cause an existential catastrophe. In 2023, hundreds of AI experts and other notable figures signed a statement declaring, "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war". Following increased concern over AI risks, government leaders such as United Kingdom prime ministerRishi Sunak and United Nations Secretary-GeneralAntónio Guterres called for an increased focus on global AI regulation.

Besides the immediate destruction of cities by nuclear blasts, the potential aftermath of a nuclear war could involve firestorms, a nuclear winter, widespread radiation sickness from fallout, and/or the temporary (if not permanent) loss of much modern technology due to electromagnetic pulses. Some scientists, such as Alan Robock, have speculated that a thermonuclear war could result in the end of modern civilization on Earth, in part due to a long-lasting nuclear winter. In one model, the average temperature of Earth following a full thermonuclear war falls for several years by 7 to 8 °C (13 to 15 degrees Fahrenheit) on average.
Early Cold War-era studies suggested that billions of humans would survive the immediate effects of nuclear blasts and radiation following a global thermonuclear war. The International Physicians for the Prevention of Nuclear War believe that nuclear war could indirectly contribute to human extinction via secondary effects, including environmental consequences, societal breakdown, and economic collapse.

Environmental disasters show how the impact of humans' alteration of the land has led to widespread and/or long-lasting consequences. These disasters have included deaths of wildlife, humans and plants, or severe disruption of human life or health, possibly requiring migration.

The dodo became extinct during the mid-to-late 17th century due to habitat destruction, overhunting, and predation by introduced mammals. It is an often-cited example of a human-driven extinction.
The Holocene extinction, also referred to as the Anthropocene extinction or the sixth mass extinction, is an ongoing extinction event caused exclusively by human activities during the Holocene epoch. This extinction event spans numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, impacting both terrestrial and marine species. Widespread degradation of biodiversity hotspots such as coral reefs and rainforests has exacerbated the crisis. Many of these extinctions are undocumented, as the species are often undiscovered before their extinctions.
Current extinction rates are estimated at 100 to 1,000 times higher than natural background extinction rates and are accelerating. Over the past 100–200 years, biodiversity loss has reached such alarming levels that some conservation biologists now believe human activities have triggered a mass extinction, or are on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has been referred to as the sixth mass extinction. However, given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed.
The Holocene extinction was preceded by the Late Pleistocene megafauna extinctions (lasting from 50,000 to 10,000 years ago), in which many large mammals – including 81% of megaherbivores – went extinct, a decline attributed at least in part to human (anthropogenic) activities. There continue to be strong debates about the relative importance of anthropogenic factors and climate change, but a recent review concluded that there is little evidence for a major role of climate change and "strong" evidence for human activities as the principal driver. Examples from regions such as New Zealand, Madagascar, and Hawaii have shown how human colonization and habitat destruction have led to significant biodiversity losses. (Full article...)

Investment is traditionally defined as the "commitment of resources into something expected to gain value over time". If an investment involves money, then it can be defined as a "commitment of money to receive more money later". From a broader viewpoint, an investment can be defined as "to tailor the pattern of expenditure and receipt of resources to optimise the desirable patterns of these flows". When expenditures and receipts are defined in terms of money, then the net monetary receipt in a time period is termed cash flow, while money received in a series of several time periods is termed cash flow stream.
In finance, the purpose of investing is to generate a return on the invested asset. The return may consist of a capital gain (profit) or loss, realised if the investment is sold, unrealised capital appreciation (or depreciation) if yet unsold. It may also consist of periodic income such as dividends, interest, or rental income. The return may also include currency gains or losses due to changes in foreign currency exchange rates.
Investors generally expect higher returns from riskier investments. When a low-risk investment is made, the return is also generally low. Similarly, high risk comes with a chance of high losses. Investors, particularly novices, are often advised to diversify their portfolio. Diversification has the statistical effect of reducing overall risk. (Full article...)

Global monthly average total ozone amount Ozone depletion consists of two related events observed since the late 1970s: a lowered total amount of ozone in Earth's upper atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbonrefrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2). Both types of ozone depletion were observed to increase as emissions of halocarbons increased.
Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn, permanent blindness, and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons, and other ozone-depleting chemicals. Over time, scientists have developed new refrigerants with lower global warming potential (GWP) to replace older ones. For example, in new automobiles, R-1234yf systems are now common, being chosen over refrigerants with much higher GWP such as R-134a and R-12. (Full article...)

Women selling produce at a market in Lilongwe, Malawi Food security is the state of having reliable access to a sufficient quantity of affordable, healthy food. The availability of food for people of any class, gender, ethnicity, or religion is another element of food protection. Similarly, household food security is considered to exist when all the members of a family have consistent access to enough food for an active, healthy life. Food-secure individuals do not live in hunger or fear of starvation. Food security includes resilience to future disruptions of food supply. Such a disruption could occur due to various risk factors such as droughts and floods, shipping disruptions, fuel shortages, economic instability, and wars. Food insecurity is the opposite of food security: a state where there is only limited or uncertain availability of suitable food.
The concept of food security has evolved over time. The four pillars of food security include availability, access, utilization, and stability. In addition, there are two more dimensions that are important: agency and sustainability. These six dimensions of food security are reinforced in conceptual and legal understandings of the right to food. The World Food Summit in 1996 declared that "food should not be used as an instrument for political and economic pressure."
There are many causes of food insecurity. The most important ones are high food prices and disruptions in global food supplies for example due to war. There is also climate change, water scarcity, land degradation, agricultural diseases, pandemics and disease outbreaks that can all lead to food insecurity. Additionally, food insecurity affects individuals with low socioeconomic status, affects the health of a population on an individual level, and causes divisions in interpersonal relationships. Food insecurity due to unemployment causes a higher rate of poverty. (Full article...)
Inclusive growth is economic growth that raises standards of livings for broad swaths of a population. It is widely accepted that inclusive growth is challenging to be achieved in the real world. Both the intangibility and long term perspective make it less desirable than other more conspicuous economic targets for policymakers.
There is a lack of a comprehensive and worldly recognised set of standards to systematically measure the inclusiveness of growth, which makes data collection and policy evaluation difficult. Proponents for inclusive growth warn that inequitable growth may have adverse political outcomes.
While the ability to deliberately engineer pathogens has been constrained to high-end labs run by top researchers, the technology to achieve this is rapidly becoming cheaper and more widespread. For example, the diminishing cost of sequencing the human genome (from $10 million to $1,000), the accumulation of large datasets of genetic information, the discovery of gene drives, and the discovery of CRISPR. Biotechnology risk is therefore a credible explanation for the Fermi paradox. (Full article...)
During the 1990s, the U.S. Congress had passed legislation that intended to expand affordable housing through looser financing rules, and in 1999, parts of the 1933 Banking Act (Glass–Steagall Act) were repealed, enabling institutions to mix low-risk operations, such as commercial banking and insurance, with higher-risk operations such as investment banking and proprietary trading. As the Federal Reserve ("Fed") lowered the federal funds rate from 2000 to 2003, institutions increasingly targeted low-income homebuyers, largely belonging to racial minorities, with high-risk loans; this development went unattended by regulators. As interest rates rose from 2004 to 2006, the cost of mortgages rose and the demand for housing fell; in early 2007, as more U.S. subprime mortgage holders began defaulting on their repayments, lenders went bankrupt, culminating in the bankruptcy of New Century Financial in April. As demand and prices continued to fall, the financial contagion spread to global credit markets by August 2007, and central banks began injecting liquidity. In March 2008, Bear Stearns, the fifth largest U.S. investment bank, was sold to JPMorgan Chase in a "fire sale" backed by Fed financing.
A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location. Colder and higher latitude waters are capable of absorbing more CO2. This can cause acidity to rise, lowering the pH and carbonate saturation levels in these areas. There are several other factors that influence the atmosphere-ocean CO2 exchange, and thus local ocean acidification. These include ocean currents and upwelling zones, proximity to large continental rivers, sea ice coverage, and atmospheric exchange with nitrogen and sulfur from fossil fuel burning and agriculture.
A lower ocean pH has a range of potentially harmful effects for marine organisms. Scientists have observed for example reduced calcification, lowered immune responses, and reduced energy for basic functions such as reproduction. Ocean acidification can impact marine ecosystems that provide food and livelihoods for many people. About one billion people are wholly or partially dependent on the fishing, tourism, and coastal management services provided by coral reefs. Ongoing acidification of the oceans may therefore threaten food chains linked with the oceans. (Full article...)

Tar sands in Alberta, 2008. Oil is one of the most used resources by humans. Resource depletion occurs when a natural resource is consumed faster than it can be replenished. The value of a resource depends on its availability in nature and the cost of extracting it. By the law of supply and demand, the scarcer the resource the more valuable it becomes. There are several types of resource depletion, including but not limited to: wetland and ecosystem degradation, soil erosion, aquifer depletion, and overfishing. The depletion of wildlife populations is called defaunation.
It is a matter of research and debate how humanity will be impacted and what the future will look like if resource consumption continues at the current rate, and when specific resources will be completely exhausted. (Full article...)

Overconsumption describes a situation where consumers overuse their available goods and services to where they cannot, or do not want to, replenish or reuse them. In microeconomics, this is the point where the marginal cost of a consumer is greater than their marginal utility. The term overconsumption is quite controversial and does not necessarily have a single unifying definition. When used to refer to natural resources to the point where the environment is negatively affected, it is synonymous with the term overexploitation. However, when used in the broader economic sense, overconsumption can refer to all types of goods and services, including artificial ones, e.g., "the overconsumption of alcohol can lead to alcohol poisoning." Overconsumption is driven by several factors of the current global economy, including forces like consumerism, planned obsolescence, economic materialism, and other unsustainable business models, and can be contrasted with sustainable consumption.
Defining the amount of a natural resource required to be consumed for it to count as "overconsumption" is challenging because defining a sustainable capacity of the system requires accounting for many variables. A system's total capacity occurs at regional and worldwide levels, which means that specific regions may have higher consumption levels of certain resources than others due to greater resources without overconsuming a resource. A long-term pattern of overconsumption in any region or ecological system can cause a reduction in natural resources, often resulting in environmental degradation. However, this is only when applying the word to environmental impacts. When used in an economic sense, this point is defined as when the marginal cost of a consumer is equal to their marginal utility. Gossen's law of diminishing utility states that at this point, the consumer realizes the cost of consuming/purchasing another item/good is not worth the amount of utility (also known as happiness or satisfaction from the good) they had received, and therefore is not conducive to the consumer's wellbeing.
When used in the environmental sense, the discussion of overconsumption often parallels population size, growth, and human development: more people demanding a higher quality of living requires greater extraction of resources, which causes subsequent environmental degradation, such as climate change and biodiversity loss. Currently, the inhabitants of high-wealth, "developed" nations consume resources at a rate almost 32 times greater than those of the developing world, making up most of the human population (7.9 billion people). However, the developing world is a growing consumer market. These nations are quickly gaining more purchasing power. The Global South, which includes cities in Asia, America, and Africa, is expected to account for 56% of consumption growth by 2030, meaning that if current trends continue, relative consumption rates will shift more into these developing countries, whereas developed countries would start to plateau. Sustainable Development Goal 12, "responsible consumption and production", is the main international policy tool with goals to abate the impact of overconsumption. (Full article...)
The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 1970s by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense in collaboration with universities and researchers across the United States and in the United Kingdom and France. The ARPANET initially served as a backbone for the interconnection of regional academic and military networks in the United States to enable resource sharing. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, encouraged worldwide participation in the development of new networking technologies and the merger of many networks using DARPA's Internet protocol suite. The linking of commercial networks and enterprises by the early 1990s, as well as the advent of the World Wide Web, marked the beginning of the transition to the modern Internet, and generated sustained exponential growth as generations of institutional, personal, and mobilecomputers were connected to the internetwork. Although the Internet was widely used by academia in the 1980s, the subsequent commercialization of the Internet in the 1990s and beyond incorporated its services and technologies into virtually every aspect of modern life.
Virtually all civilizations have suffered such a fate, regardless of their size or complexity. Most never recovered, such as the Western and Eastern Roman Empires, the Maya civilization, and the Easter Island civilization. However, some of them later revived and transformed, such as China, Greece, and Egypt.
Anthropologists, historians, and sociologists have proposed a variety of explanations for the collapse of civilizations involving causative factors such as environmental degradation, depletion of resources, costs of rising complexity, invasion, disease, decay of social cohesion, growing inequality, extractive institutions, long-term decline of cognitive abilities, loss of creativity, and misfortune. However, complete extinction of a culture is not inevitable, and in some cases, the new societies that arise from the ashes of the old one are evidently its offspring, despite a dramatic reduction in sophistication. Moreover, the influence of a collapsed society, such as the Western Roman Empire, may linger on long after its death. (Full article...)

Early in the COVID-19 pandemic, convention centers (pictured here) were deemed to be ideal sites for temporary hospitals, due to their existing infrastructure (electrical, water, sewage). Hotels and dormitories were also considered appropriate because they can use negative pressure technology.
A pandemic (/pænˈdɛmɪk/pan-DEM-ik) is an epidemic of an infectious disease that has a sudden increase in cases and spreads across a large region, for instance multiple continents or worldwide, affecting a substantial portion of the human population. Widespread endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide.
Throughout human history, there have been a number of pandemics of diseases such as smallpox. The Black Death, caused by the Plague, caused the deaths of up to half of the population of Europe in the 14th century. The term pandemic had not been used then, but was used for later epidemics, including the 1918 H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the deadliest pandemic in history. The most recent pandemics include the HIV/AIDS pandemic, the 2009 swine flu pandemic and the COVID-19 pandemic. Almost all these diseases still circulate among humans though their impact now is often far less.

Image 1San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.
Image 2A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
Image 3An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.

Image 5Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.
Image 6NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
Image 7One of two monkey selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
Image 8The sperm whale is the largest toothed animal on Earth. The species was hunted extensively by humans throughout history, until protected by a worldwide moratorium on whaling starting in 1985–86.
Image 10Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.
Image 11The Door to Hell is a natural gas field in Derweze, Turkmenistan, which has been burning since 1971 when it was ignited by Soviet scientists who expected it to burn out within days. They were trying to prevent the release of poisonous gases. The name "Door to Hell" was given to the field by locals. The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).
Image 12The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.
Image 13A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.
Image 14Lucky Diamond Rich (b. 1971) is a New Zealand-born performance artist and street performer who holds the Guinness World Record for most tattooed man, taking the title from Tom Leppard in 2006. He is recognized by Guinness as being covered in tattoos over 100% of his body, including the inside of his eyelids, ears, and mouth.
Image 16The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Image 17Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.
Image 18Sandboarding is a boardsport similar to snowboarding, but competitions take place on sand dunes rather than snow-covered mountains. Here, a member of the US Navy sandboards down a dune in Jebel Ali, Dubai.
Image 19The Hubble Extreme Deep Field is an image of a small area of space in the constellation Fornax released by NASA on September 25, 2012. The successor to the Hubble Ultra-Deep Field, this image was compiled from 10 years of previous images with a total exposure time of two million seconds, or approximately 23 days.
Image 23An overhead view of Skylab, the United States' first space station, in Earth orbit as photographed from the Skylab 4 Command and Service Modules. Skylab 4 was the last mission to Skylab and brought back its final crew; this photograph was the last one taken of the station before the mission re-entered Earth's atmosphere and disintegrated in 1979.
Image 24The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellationUrsa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.

Image 26The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.
Image 28A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
Image 29The Aqueduct of Segovia is a Roman aqueduct located in Segovia, Spain that transports water from the Rio Frio. It is thought to have been constructed during the 1st century CE. One of the most significant and best-preserved ancient monuments left on the Iberian Peninsula, the aqueduct is considered a symbol of Segovia and is present on the city's coat of arms.
Image 30A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
Image 38The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.
Image 44A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.

Thanks in advanceCstubbies (talk) 12:40, 19 January 2008 (UTC)
A valuable service
I think you need recognition for doing the job of ten other editors, and doing it out of altruism and genuine belief in Wikipedia. Not many editors here have the same good attitude and provide the same service as you - I don't have any specific point to put across, but I thought you should just be prodded and reminded that you do a lot of good around here, in the hope you'll keep it up. Kudos! Seegoon (talk) 17:43, 25 January 2008 (UTC)
Just a note, I've made a minor update to your contributions. To reiterate my edit summary, you put in a tonne of effort there, and you deserve to be credited for it :) Feel free to revert, nonetheless. Regards, AGK (contact) 16:44, 29 February 2008 (UTC)

Many years ago, back before I had created my current account, I created a humble little userspace navigation menu based off of two of your menus from the User Page Design Center (initially 15, but ultimately 6). Over the years it has grown, but I don't know if I ever would have started it without seeing your menus first. I just want to thank you for putting the effort into creating those menus and then sharing them at the Design Center where they have been helpful for people like me. I hope you don't mind me borrowing from your hard work! Thanks again and take care! Michael Barera (talk) 03:30, 13 January 2013 (UTC)

Hi there! I just wanted to let you know that I think your planet outlines are really cool. I have long thought it was a shame that only Wikipedians seem to know about Books or Portals, because they are really great tools for structuring knowledge (while everyone loves diving down the Wikipedia rabbit hole, we could really do with some better content organization). The outlines strike me as a great way to bring that sort content organization to mainspace, where it will actually reach a large number of readers. I notice that I am the first one to edit them besides yourself, and I hope you know that I do so with love.
What a Brilliant Idea Barnstar
Great idea with the outline articles - a great solution to a need for better mainspace-based content structuring! I see from WP:Outlines that you actually came up with this concept some years ago, but this is the first I've noticed it. A2soup (talk) 02:46, 8 February 2017 (UTC)

The Portal Barnstar
The Portal Barnstar is awarded to Wikipedians who have made significant contributions to topic portals. Awarded to Transhumanist for his overly enthusiastic efforts regarding the portal system and WikiProject Portals. – Lionel(talk) 11:02, 30 April 2018 (UTC)
Transhumanist, thank you for your extraordinary efforts on behalf of portals. It reminds me of the time when a series of attacks on scientific bibliographies led to the formation of WikiProject Bibliographies. I don't understand why your detractors are so passionate about deleting portals, but your actions have been a model for how to deal with an attack constructively.

The Article Rescue Barnstar
May all who see this barnstar know that The Transhumanist made a valiant and commendable effort for defending the portal namespace from deletion. It preserved countless hours of work initially invested into creating the content. Moreoever, The Transhumanist, is doing a yeoman's job in attempting to improve the content within with portal namespace. RightCowLeftCoast (talk) 00:24, 26 May 2018 (UTC)
@RightCowLeftCoast: Thank you. I feel honored. Please keep in mind that I have not been working alone. Credit goes to the nearly 400 editors who came forward to speak up for the keeping of portals. And although the RfC to delete all portals is over, the job of defending portals from deletion is not. For the portal namespace to be retained in the long term, the portals in it will need to be improved to a worthy quality level, otherwise we may see more deletion attempts. This task is far more than a single editor can handle. Fortunately, many editors have come forward to meet the challenge. Working to develop portals and the entire portal system, is a team of 80 editors who are diligently redesigning, upgrading, updating, and maintaining portals. They are the members of the Portals WikiProject, and without them there might be no portals. They are doing a wonderful job, and I am very proud of them. Thank you. — The Transhumanist 17:22, 26 May 2018 (UTC)
Thank you for your thoughts and efforts regarding portals, for the concept of outlines, for sectional redirects, for articles such as Life Extension Foundation, for service from 2006, including portal philosophy and user page design center, - repeating (1 & 4 June 2009): you are an awesome Wikipedian!
Thank you. I looked, but couldn't figure out what 1 & 4 June 2009 were referring to. Just curious. — The Transhumanist 19:26, 4 June 2018 (UTC)

San Francisco Bay shrouded in fog, as seen from the Marin Headlands looking east. The fog of San Francisco is a kind of sea fog, created when warm, moist air blows from the central Pacific Ocean across the cold water of the California Current, which flows just off the coast. The water is cold enough to lower the temperature of the air to the dew point, causing fog generation. In this photo, the towers of the Golden Gate Bridge can be seen poking through the fog, and the Bay Bridge is visible in the distance.
A man engaging in big wave surfing at Mavericks, located just north of Half Moon Bay, California. Big wave surfing is a discipline within surfing in which experienced surfers paddle into or are towed onto waves which are at least 20 ft (6.1 m) high, and is a hazardous activity, as surfers can be pushed far beneath the surface of the water after a wipeout.
An animation of a cicada undergoing ecdysis, the molting of the exoskeleton in arthropods and related groups. Since the cuticula of these animals is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia. Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.
Devastation caused by Hurricane Katrina in New Orleans, Louisiana during 2005, shown here looking down on Interstate 10 at West End Boulevard towards Lake Pontchartrain. Over 1,800 people were confirmed dead with 705 still missing. It was the costliest Atlantic hurricane in history causing around $86 billion in damage. This photo shows flooded roadways as the United States Coast Guard conducted initial damage assessment overflights of New Orleans on Monday, August 29, 2005. The city flooded due primarily to the failure of the levee system. Many who remained in their homes had to swim for their lives, wade through deep water, or remain trapped in their attics or on their rooftops.
NGC 1300 is a barred spiral galaxy located roughly 69 million light-years away in the direction of the constellation Eridanus. In its core, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long.
One of two monkey selfies taken by Celebes crested macaques using equipment belonging to the British nature photographer David Slater. In mid-2014, the images' hosting on Wikimedia Commons was at the centre of a dispute over whether copyright could be held on artworks made by non-human animals. Slater argued that, as he had "engineered" the shot, he held copyright, while Wikimedia considered the photographs public domain on the grounds that they were made by an animal rather than a person. In December 2014, the United States Copyright Office stated that works by a non-human are not subject to US copyright, a view reaffirmed by a US federal judge in 2016.
The sperm whale is the largest toothed animal on Earth. The species was hunted extensively by humans throughout history, until protected by a worldwide moratorium on whaling starting in 1985–86.
Tracy Caldwell Dyson in the Cupola module of the International Space Station, observing the Earth below during Expedition 24. Caldwell Dyson is an American chemist and astronaut. She was selected by NASA in 1998 and made her first spaceflight in August 2007 on the STS-118 mission aboard Space Shuttle Endeavour.
Crash landing of an F6F Hellcat into the port side 20mm gun gallery of the USS Enterprise, November 10, 1943. Lieutenant Walter L. Chewning, Jr., USNR, the Catapult Officer, is climbing up the plane's side to assist the pilot from the burning aircraft. The pilot, Ensign Byron M. Johnson, escaped without significant injury. Note the plane's ruptured belly fuel tank.
The Door to Hell is a natural gas field in Derweze, Turkmenistan, which has been burning since 1971 when it was ignited by Soviet scientists who expected it to burn out within days. They were trying to prevent the release of poisonous gases. The name "Door to Hell" was given to the field by locals. The hot spots range over an area with a width of 60 metres (200 ft) and to a depth of about 20 metres (66 ft).
The International Space Station (ISS) as seen from the Space Shuttle Endeavour. Zarya, the first module of the ISS launched in 1998, is seen in the foreground. Since then, twenty-six Space Shuttle flights have docked with the ISS to assemble various other modules and components, which include four pairs of solar arrays seen on each side.
A dust storm rushes towards a military camp as it rolls over Al Asad Airbase, Iraq, just before nightfall on April 27, 2005. A dust storm (or sandstorm) is a meteorological phenomenon common in dry, arid and semi-arid regions, usually the result of convection currents created by intense heating of the ground. These currents then carry clouds of sand over large distances.
Lucky Diamond Rich (b. 1971) is a New Zealand-born performance artist and street performer who holds the Guinness World Record for most tattooed man, taking the title from Tom Leppard in 2006. He is recognized by Guinness as being covered in tattoos over 100% of his body, including the inside of his eyelids, ears, and mouth.
aurora australis, as seen from the International Space Station. Aurorae are natural light displays in the sky caused by the collision of energetic charged particles with atoms in the high altitude thermosphere. The particles originate in the magnetosphere and solar wind and, on Earth, are directed by Earth's magnetic field into the atmosphere.
The Leaning Tower of Pisa is the freestanding bell tower of the Cathedral of Pisa, Italy. The third oldest structure in the city's Square of Miracles, it is known worldwide for its unintended tilt. The tower's tilt began during construction in the 12th century, caused by an inadequate foundation on ground too soft on one side to properly support the structure's weight. The tilt gradually increased until the tower was stabilized (and the tilt partially corrected) by efforts in the late 20th and early 21st centuries. The tower, which measures 55.86 metres (183.27 feet) from the ground on the low side and 56.67 metres (185.93 feet) on the high side, has been listed as a UNESCO World Heritage Site since 1987.
Glaucus atlanticus is a species of small, blue sea slug. This pelagic aeolid nudibranch floats upside down, using the surface tension of the water to stay up, and is carried along by the winds and ocean currents. The blue side of their body faces upwards, blending in with the blue of the water, while the grey side faces downwards, blending in with the silvery surface of the sea. G. atlanticus feeds on other pelagic creatures, including the Portuguese man o' war.
Sandboarding is a boardsport similar to snowboarding, but competitions take place on sand dunes rather than snow-covered mountains. Here, a member of the US Navy sandboards down a dune in Jebel Ali, Dubai.
The Hubble Extreme Deep Field is an image of a small area of space in the constellation Fornax released by NASA on September 25, 2012. The successor to the Hubble Ultra-Deep Field, this image was compiled from 10 years of previous images with a total exposure time of two million seconds, or approximately 23 days.
United States Navy personnel engage in Special Patrol Insertion/Extraction (SPIE) training between a Sikorsky SH-60 Seahawk helicopter and the USS Dwight D. Eisenhower (CVN-69). SPIE involves either a person or goods being lowered from or raised to a helicopter via a cable above terrain on which landing would be difficult.
Crowds surrounding the Reflecting Pool, during the August 28 1963 March on Washington for Jobs and Freedom. An estimated 200,000 to 500,000 people participated in the march, which featured Martin Luther King Jr.'s famous "I Have a Dream" speech. It was a major factor leading to the passage of the Civil Rights Act of 1964 and the 1965 Voting Rights Act. The march was also condemned by the Nation of Islam and Malcolm X, who termed it the "farce on Washington".
An overhead view of Skylab, the United States' first space station, in Earth orbit as photographed from the Skylab 4 Command and Service Modules. Skylab 4 was the last mission to Skylab and brought back its final crew; this photograph was the last one taken of the station before the mission re-entered Earth's atmosphere and disintegrated in 1979.
The Pinwheel Galaxy is a face-on spiral galaxy located 21 million light-years away in the constellation Ursa Major. It was first discovered by Pierre Méchain on March 27, 1781, and communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries. This image, released on February 28, 2006, is composed of 51 individual exposures, as well as some extra ground-based photos. At the time of its release, it was the largest and most detailed image of a galaxy by the Hubble Space Telescope.

The American Bison, or Buffalo, is the largest terrestrial mammal in North America, and once inhabited the Great Plains in massive herds. They were central to the lives of Native American tribes. This pile of bison skulls from the 1870s illustrates the extent of their slaughter in the 19th century by settlers: from a population of about 60 million in 1800 to as few as 750 in 1890. They have since been reintroduced into the wild and are no longer considered a high risk endangered species.
The 2004 Indian Ocean earthquake was a magnitude 9.15, undersea earthquake that occurred at 00:58:53 UTC on December 26 2004. The earthquake generated a tsunami that killed more than 150,000 people around the Indian Ocean, making it one of the deadliest disasters in modern history. This photograph shows the tsunami as it reached Ao Nang, Thailand.
A neutral density filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The filter reduces the amount of light entering the lens, allowing the photographer to select combinations of aperture, exposure time and sensor sensitivity to avoid overexposed pictures. It would normally be attached to the lens, but is hand-held here to illustrate the effect.
The Aqueduct of Segovia is a Roman aqueduct located in Segovia, Spain that transports water from the Rio Frio. It is thought to have been constructed during the 1st century CE. One of the most significant and best-preserved ancient monuments left on the Iberian Peninsula, the aqueduct is considered a symbol of Segovia and is present on the city's coat of arms.
A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
The mushroom cloud from the Ivy Mike nuclear test, one of two tests conducted as part of Operation Ivy at the Pacific Proving Grounds on Elugelab in the Marshall Islands. Mike was the first successful full-scale test of a multi-megaton thermonuclear weapon, and it left an underwater crater 6,240 ft (1,900 m) wide and 164 ft (50 m) deep where the island had been.

The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota. Once the third-busiest bridge in the state, it suddenly collapsed on August 1, 2007, killing 13 and injuring 145. Rescue of people stranded on the bridge was complete in three hours, while recovery of bodies—involving 75 local, state and federal agencies—took three weeks. An NTSB investigation cited a design flaw as the likely cause of the collapse, noting that a too-thin gusset plate ripped along a line of rivets.
American astronaut Eugene Cernan (born March 14, 1934), shown here on the surface of the Moon during the Apollo 17 mission, the last time any human has set foot on it. In that final lunar landing mission, launched December 7, 1972, Cernan became "the last man on the moon" since he was the last to re-enter the Apollo Lunar Module during its third and final extra-vehicular activity. Prior to this, Cernan had also gone into space twice on the Gemini 9A and Apollo 10 missions.
Astronaut Buzz Aldrin saluting the flag of the United States, part of the Lunar Flag Assembly, during Apollo 11. The Lunar Flag Assembly was designed to survive a Moon landing and to appear to "wave" as it would in a breeze on Earth. This flag fell over when the Lunar Module Eagle took off.
The mushroom cloud caused by the detonation of the "Fat Man" bomb during the atomic bombing of Nagasaki, Japan in 1945, rising approximately 18 kilometres (11 mi) above the hypocenter.
A swan created using modular origami, a paperfolding technique which uses two or more sheets of paper to create a larger and more complex structure than possible with single-piece origami techniques. Each individual sheet of paper is folded into a module, or unit, and then modules are assembled into an integrated flat shape or three-dimensional structure by inserting flaps into pockets created by the folding process. These insertions create tension or friction that holds the model together.
Atlantic White-sided Dolphins, on a concrete-floored dock at the port of Hvalba, which is in the Faroe Islands, north of the United Kingdom. Whaling in the Faroe Islands has been practised since at least the 10th century. It is strongly regulated by Faroese authorities and is approved by the International Whaling Commission.
