Generation timeline

I see you have been fairly active on the generation timeline interactive image at https://en.wikipedia.org/wiki/File:Generation_timeline.svg I don't know how to edit the images and I don't want to revert back to an image from June 3 2024, but somehow in the changes after that date the explainer in the top left got lost only on the english version. without that example it is just a bunch of trapezoids with shading that means nothing without the explainer that it is groups of cohorts and turns 18 etc. would you be able to add that back? I had used this before as a refrence to explain generations but then went back to it this week and was wondering where the rest of the image went. HandsomeRob1977 (talk) 19:05, 7 January 2025 (UTC)[reply]

Hi HandsomeRob1977, You have uncovered a bug in Wikipedia's thumbnail rendering: When an SVG file has en-simple localisation (meant for "simple" English), it overrides the default en (ordinary English) one. If lang is not specified, it should default to the en version, but instead uses the en-simple version intended for infobox thumbnails and has no legend or background bars:

A workaround is to specify a non-existent language code such as lang=dummy as above to force the default version with legend and background bars. Does that help? Cheers, cmɢʟee⎆τaʟκ 14:55, 17 February 2025 (UTC)[reply]

Non-inertial reference frame

Hello, this is an gif/animation request for non-inertial reference frames. This gif is alright, but I think it could be improved if different basis vectors had different colours, maybe adding the axis of rotation as a dashed line and maybe adding a point with a vector from both coordinate systems to this point. Maybe it would look too cluttered... I think I would have to put a lot of effort to make such an image, but I think it could be easier for you and you could do a good job with it, if you would do it :) --Gustamons (talk) 16:40, 16 February 2025 (UTC)[reply]

Hi Gustamons, I can make that in POV-Ray but first need to clarify what you mean by "a point with a vector from both coordinate systems to this point". Do you mean an arrow from the origin to the point? cmɢʟee⎆τaʟκ 15:09, 17 February 2025 (UTC)[reply]

Hey Cmglee, yes, from the origin of both coordinate systems to a point, kind of like in this image. The rotating coordinate system could also have a varying rate of rotation, but I am not sure how one can visualize this without it looking weird... I also don't know how cluttered this image would be. Maybe just different colours for basis vectors and an axis of rotation will do, while the point and varying rotation rate could be added if it doesn't clutter the image or make it look odd. --Gustamons (talk) 16:07, 17 February 2025 (UTC)[reply]

@Gustamons: Is this what you had in mind? cmɢʟee⎆τaʟκ 14:34, 19 February 2025 (UTC)[reply]

This is a good base gif!

I hope this isn't moving the goalposts too much- I think since non-inertial reference frames are a physics topic, this gif could showcase the different fictitious forces that arise in the rotating reference frame.

Maybe the vector to the points in each reference frames could be removed to make room for the force showcase.

Now thinking about it, I suppose the rotation axis should faces inside/outside the screen(so maybe? no need to show it), because all the forces are cross products of the angular velocity and so are perpendicular to it. It is easier to see movement in the screen plane instead of depth.

To my understanding, the force equation for rotating frames is

{\begin{aligned}\mathbf {F} &=\mathbf {F'} +m{\frac {\mathrm {d} {\boldsymbol {\omega }}}{\mathrm {d} t}}\times \mathbf {r} '+2m{\boldsymbol {\omega }}\times \mathbf {v} '+m{\boldsymbol {\omega }}\times ({\boldsymbol {\omega }}\times \mathbf {r} ')=m\mathbf {a} \end{aligned}}

, where (') indicates the rotating reference frame^[1]

I think it would be cool, if the point started close to the coordinate origin, then with

\mathbf {F'} =0

, Coriolis and centrifugal force would kick in and accelerate the particle. The trajectory in the inertial frame would look kind of like this. Then the

\mathbf {F'}

could be big, make velocity to zero and then become smaller to balance the forces for a while(so it stands still in the inertial frame). Then I suppose

\mathbf {F'} =0

again and making the

{\frac {\mathrm {d} {\boldsymbol {\omega }}}{\mathrm {d} t}}

negative would create Euler's force (if it were positive, it shares the direction with centrifugal force, so it being negative is more illustrative I think, as at least they are in opposite directions). I am not sure how to end the gif...

I think the forces should be vectors attached to the particle with their length showing magnitude.

Anyways, this seems like a lot to ask and I am kind of amazed that you would reply and even create a base gif from a strangers request... Keep being you :D --Gustamons (talk) 21:46, 19 February 2025 (UTC) Gustamons (talk) 21:46, 19 February 2025 (UTC)[reply]

@Gustamons: That's quite different from your initial request. If the rotation axis is perpendicular to the screen, it would appear as just a dot.

The only major change I'm prepared to do is to keep the point stationary while the basis vectors rotate, the yellow vector continuously pointing from the origin to that point.

I'll upload my POV-Ray code. Feel free to edit it as needed. cmɢʟee⎆τaʟκ 01:51, 20 February 2025 (UTC)[reply]

That is understandable. Maybe its for the best as this gif is already alright. Thanks! --Gustamons (talk) 20:08, 21 February 2025 (UTC)[reply]

Hello Cmglee - Your Sankey Diagram for The Earth's Energy Budget.

Hello Cmglee.

I am beginning to learn about The Earth's Energy Budget.

I have been reading This Wikipedia Article:

https://en.wikipedia.org/wiki/Earth's_energy_budget

Where Your Wonderful Sankey Diagram is illustrated:

https://en.wikipedia.org/wiki/File:Earth_heat_balance_Sankey_diagram.svg

I have gathered some more Earth Energy Budget Diagrams here:

https://ukmjenkins.wordpress.com/earth-energy-budget

Two of These Earth Energy Budget Diagrams,

clearly illustrate The Loops of Energy,

in The Absorption, and The Radiation, of Energy at The Surface of The Earth,

and The Longwave Infrared Energy radiated, back to Earth,

and back into Space, by The Greenhouse Effect.

I have been looking at These Diagrams,

and I am trying to comprehend Them,

and I am trying to comprehend The Greenhouse Effect,

and The Resulting Earth's Energy Imbalance,

at The Top of The Atmosphere.

I really love Your Sankey Diagram.

Please could You please try to study,

The Earth Energy Budget Diagrams that I have gathered,

and please could You please try to create,

A New Sankey Diagram that assimilates All The Information,

in All These Earth Energy Budget Diagrams,

and that gives An Example Value for The Earth's Energy Imbalance,

at The Top of The Atmosphere, please ?

Please forgive My Way of writing,

It is how I need to work, to be able to be clear, please.

@Ukmjenkins: Thanks for your message. I'm afraid it will be very difficult if not impossible to combine the data from all your images. For one, some of them don't balance the incoming and outgoing energy, implying that the Earth is continuously heating up or cooling down.

Whirl illustration

Hi! I appreciate the concept and effort behind the new illustration on Mice problem, but it hurts my eyes due to the intense moiré effect. Would you consider making a different version that is less visually intense? Thank you! Dreamyshade (talk) 18:37, 3 September 2025 (UTC)[reply]

@Dreamyshade: Thanks for the feedback and sorry to hear. Can you tell exactly what causes the issue? Is it the contrast between black and white (will other colours help)? Alternatively, if the frequency is lower, such as File:2deg_square_whirl.svg, is it better? Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 22:20, 3 September 2025 (UTC)[reply]

Sorry, both of the images have the problem for me. I believe they cause eye strain for me due to the dense, high-contrast striped patterns. For context, my eyes are also sensitive to flashing lights and some kinds of short, repetitive animations. I don't have epilepsy or migraines, but the triggers are similar. This paper seems to have some helpful explanations: "A neurological basis for visual discomfort" (full article). Dreamyshade (talk) 01:01, 4 September 2025 (UTC)[reply]

Oh, this website has a better overview, based on that person's research about visual stress. 2025 article: "A neurological basis for visual stress and its treatment with coloured filters".

This article is also helpful: "The effects of visual discomfort and chromaticity separation on neural processing during a visual task": "Stimuli that are particularly aversive are high contrast, mid-range spatial frequency (2–8 cpd) square wave gratings (stripes), with 50% duty cycle. These stimuli can induce discomfort and headaches in individuals with migraine and elicit seizures in patients with photosensitive epilepsy. In neurotypical individuals, they can induce discomfort, visual illusions, and large neural responses in visual cortex, that are heightened in migraine."

Thanks for asking, interesting to find out that there's been a fair bit of study of this experience that I have! Dreamyshade (talk) 01:17, 4 September 2025 (UTC)[reply]

@Dreamyshade: I see. How about putting it in a collapsed infobox with a warning, like so? Can you word it appropriately? Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 14:00, 5 September 2025 (UTC)[reply]

@Cmglee: Sorry, I edited your example to stop displaying it on this page because the image causes eye strain for me. I recommend removing it from the article, because the existing illustrations explain the concept sufficiently. If you want to add something else, I suggest adding a new illustration that has much lower contrast and naturalistic colors. For example, photos of the bronze sculpture Icosaspirale by Charles O. Perry demonstrate the whirl without hurting me. Another photo that demonstrates the whirl. Dreamyshade (talk) 19:12, 5 September 2025 (UTC)[reply]

@Dreamyshade: Does the image not appear until [show] is clicked? If it doesn't, what browser and operating system are you using? The sculpture is a 3D version and is much more complicated than the whirl described. cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 22:45, 5 September 2025 (UTC)[reply]

@Cmglee: Added a harmless image for testing, so I can figure out the circumstances where it shows unexpectedly (I think it was while I was in editing mode). The underlying issue is that I don't think it's a good idea to add a harmful image to the article at all, because it's not necessary for explaining the topic adequately. The sculpture is just an example of colors and patterns that aren't stressful for my eyes. Dreamyshade (talk) 00:12, 6 September 2025 (UTC)[reply]

A tiling by polyomino «C» & «M» & «G» & «L» & «E»?

Hi,

Thank you for your collaboration on the Golden triangle (mathematics) article!

About your nice Cmglee logo:

What about adding to your userpage, as a «wallpaper», a tiling by polyomino «C» & «M» & «G» & «L» & «E» (if possible, with twice as many «E»s as the other letters)? :-P :-)

Cheers, —JavBol (talk) 15:53, 6 October 2025 (UTC)[reply]

Thanks for the compliment and suggestion, @JavBol: I originally made that logo in the style of File:3D-ambigram_GEB_(Gödel_Escher_Bach).png with my commons:category:4-3-2_trimetric_projection and hadn't thought about tiling a plane with these letters. Can you suggest how it's possible to do do? Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 18:20, 6 October 2025 (UTC)[reply]

@Cmglee:

Would you allow the letters to be (in their normal orientation & also) in several symmetric orientations?

Would you allow the «C» to be a bit smaller than the other letters?

If yes & yes, then I could suggest how it might be possible to make such a tiling of the plane (I've not really tried my little ideas, because I'm totally fed up with drawing tilings)… :-P

@Cmglee:

Your polycube «ABC» & its shadow polyomino «A» are better than the previous ones.

About the «CMGLEE» tiling:

I've finally managed to draw a (rather large) pattern for a (periodic):

Plane tiling by polyomino «C»s, «M»s, «G»s, «L»s, «E»s, & by their point-symmetric shapes ~ 4 colors.png. But:

its «C»s are a bit smaller than its «L»s, which are a bit smaller than its other letters;

it has more «C»s & more «L»s (& rightly more «E»s) than «M»s & «G»s…

Should I upload it to Wikimedia Commons, so that you can see it?

If so, should I change its name? (My English is not always idiomatic…) —JavBol (talk) 20:02, 9 October 2025 (UTC)[reply]

Yes, please, if you could. Thanks! cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 20:47, 10 October 2025 (UTC)[reply]

@Cmglee:

IMHO, the «B» part of the polycube «ABC» & the shadow polyomino «B» would look better like this (without the blank lines):

□□□

□■□

□□□□

□■■□

□□□□.

About the «CMGLEE» tiling:

I've finally managed to draw (7/4 of) a (rather large) pattern for a (periodic):

Plane tiling by polyomino «C»s, «M»s, «G»s, «L»s, «E»s, & by their point-symmetric shapes ~ 4 colors.png,

where only the «C»s are a bit smaller than the other letters

(but there still are more «C»s & more «L»s (& rightly more «E»s) than «M»s & «G»s).

Should I change its name, for upload to Commons? (My English is not always idiomatic…) —JavBol (talk) 00:12, 14 October 2025 (UTC)[reply]

Thanks, @JavBol:. I'd rather have the right-hand side vertical so that the B is in a plane. I could of course lean the A the other way e.g.⬛⬜⬜⬜ ⬛⬜⬛⬜ ⬛⬜⬜⬜ ⬜⬛⬛⬜ ⬜⬛⬛⬜ but it looks assymetrical.

Well done in partially achieving the tiling. I think it's best to keep the current file. How about calling the tiling commons:file:cmglee_tiling.svg?

Thanks in advance, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 14:10, 15 October 2025 (UTC)[reply]

@Cmglee:

My latest suggestion seems to be unclear. Of course, the right-hand side of the polycube «ABC» should remain vertical, the polycube «B» should remain in a plane, & the «A»s should remain symmetric.

My suggestion is clearer when drawn with your (adapted) smart source code:⬜⬜⬜ ⬜⬛⬜ ⬜⬜⬜⬜ ⬜⬛⬛⬜ ⬜⬜⬜⬜for base length 4, or:⬜⬜⬜⬜ ⬜⬛⬛⬜ ⬜⬜⬜⬜⬜ ⬜⬛⬛⬛⬜ ⬜⬜⬜⬜⬜for base length 5.

About the «CMGLEE» tiling:

About naming its file «file:CMGLEE tiling."extension"»: OK.

About its file format: I've drawn only the outlines of the polyomino letters, not the sides of their unit squares. So, you will probably redraw & continue the tiling, & refine your image with your powerful softwares. So: is it important for you that I upload an SVG file, or is it OK with you if I upload a PNG file? :-P —JavBol (talk) 21:10, 15 October 2025 (UTC)[reply]

@JavBol: Good point. I mistakenly though you referred to the "A". The "B" indeed looks better.

Any name or format is fine. If I think it's suitable, I can redraw it as SVG.

Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 15:06, 18 October 2025 (UTC)[reply]

@Cmglee: I hope you like these 21/12 = 7/4 of pattern:

Of course, feel free to change any color or/& the line thickness, feel free to add the sides of the unit squares, feel free to make the (English) caption or/& description more idiomatic…

I can upload an SVG version of this file, if that makes things easier for you. —JavBol (talk) 18:35, 18 October 2025 (UTC)[reply]

@JavBol: That's beautiful, thanks! I really like how you nested the C and L. Also smart of you to reuse E as M.

Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 00:40, 19 October 2025 (UTC)[reply]

@Cmglee: Thanks. I've drawn many such tilings; so, now I know a few tricks to tile the plane in this style. Perhaps you could enhance this tiling by making its colors soft, a bit as those of your Cmglee logo already are (if you agree with this suggestion).

About the polycube «ABC» (when you find the inclination to update it): what about showing the edges of its unit cubes (if you have a software that enables you to easily do so)? —JavBol (talk) 01:46, 19 October 2025 (UTC)[reply]

@JavBol: Updated File:3d-ambigram.svg. Better?

Re tiling, nice to know a tesselation enthusiast. I was intrigued by Escher's work many years ago. As a challenge, I'd try to three-colour it. No idea if it's possible... cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 23:14, 19 October 2025 (UTC)[reply]

@Cmglee:

About the polycube «ABC»: Personally, I find it better now. But the small parallelepiped that you've just moved from left to right should also be moved up by 2 length units (so that the shadow polyomino «A» doesn't become a shadow polyomino «8»); shouldn't it?

About Escher: Please, tell me which of his many works you would try to 3-color. :-) —JavBol (talk) 00:21, 20 October 2025 (UTC)[reply]

You're correct: I realised my mistake and fixed it in the latest upload.

I haven't really thought about three-colouring Escher's tiling, but they're inadmissible on Wikipedia due to copyright regardless. cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 09:46, 20 October 2025 (UTC)[reply]

@Cmglee:

Just a little remark about the polycube «ABC»: attaching its «B» part to the other leg of its «A» part would change neither the shadow «A» nor the shadow «B», & would make the shadow «C» look like it had turned by 180° about the vertical axis; the shadow «C» would thus become more readable.

About Escher: I mistakenly thought you wanted to ask me for my opinion on the possibility of 3-coloring a specific Escher tiling. I have no particular knowledge on 3-coloring (but I could have had a look at this tiling). —JavBol (talk) 18:13, 20 October 2025 (UTC)[reply]

@JavBol: I could move the B to the front face but that would obscure most of the A. I could then move the A to the front face, but many cells in the cuboid would be occluded, so a viewer has to deduce what's in their locations (moving the bar up already hides the rightmost cell of the lower B hole, and the bottom-centre cell of the B). It's also a lot of work. I'm satisfied with an upside-down C (you likely gathered that I had to change C's orientation due to the change in its aspect ratio).

No worries if you're unfamiliar with three-colouring. As you had suggested choosing softer colours for your CMGLEE tiling, I wondered if it's possible to use only three colours. The four color theorem dictates that four are definitely enough (and the presence of T-junctions rules out using only two), but I'm unsure whether three are enough. cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 22:55, 20 October 2025 (UTC)[reply]

@Cmglee:

I'm also satisfied with an upside-down shadow «C» & most of the polycube «A» not being occluded (yes, I had guessed that you had to change the shadow «C»'s orientation due to the change in its aspect ratio). (I had written my little remark about the polycube «ABC» just in case you had preferred an upright shadow «C» & most of the polycube «A» being occluded.)

BTW: Anyway, the polycube «A» could not be moved to the front face, otherwise the shadow «B» would become:⬛⬛⬛⬛⬛ ⬛⬜⬜⬛⬛ ⬛⬛⬛⬛⬛ ⬛⬜⬜⬜⬛ ⬛⬛⬛⬛⬛; wouldn't it?

I think it's impossible to color the CMGLEE tiling with only 3 colors. Indeed: E.g., any «C» shares at least 1 line segment with 5 other letters; 5 is odd; each of these 5 letters shares at least 1 line segment with each of its 2 neighbors among these 5 letters. —JavBol (talk) 15:55, 21 October 2025 (UTC)[reply]

You're correct: the top two rows will have to be indented, so the 3D shape will look less like an A.

Great observation! It's also the reasoning why the states of continental USA cannot be three-coloured. cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 10:11, 22 October 2025 (UTC)[reply]

@JavBol: I've vectorised your design and tweaked a few letters to reduce repetition as on the right. Hope the colours are soft enough! cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 00:10, 23 October 2025 (UTC)[reply]

@Cmglee:

I hope it wasn't too much work to add so many tiles & to make a rectangular global shape! :-O

Yes, the colours are nice. My initial idea was that you might change my colors to 4 shades of blue (+ darker blue for the edges of the letters), a bit as those of your Cmglee logo already are, so that (ideally) your logo would seem to «emerge» from the CMGLEE tiling. But now, it's your tiling, using the letters of your name, so you can arrange it as you fancy. :-) —JavBol (talk) 02:24, 23 October 2025 (UTC)[reply]

Not at all. The trickest bit was figuring out that the pattern repeats after 106 cells both horizontally and vertically. I found it by trial and error and wonder if there's an analytical method.

Thanks. Blue is nice but I thought the G spirals resemble waves, so I made them crash on a sandy beach! cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 21:49, 23 October 2025 (UTC)[reply]

@Cmglee:

● On my initial image, which features an ugly but convenient unit square grid, the basic translation vectors of the tiling (corresponding to the «sides» of the pattern) are:

u = (10;8), v = (8;−36).

Lcm(8;36) = 72; 72/8 = 9, 72/36 = 2;

9u+2v = (90;72)+(16;−72) = (106;0) is a translation vector of the tiling, & gcd(9;2) = 1;

so this tiling is horizontally periodic with least period length 106 length units.

Lcm(10;8) = 40; 40/10 = 4, 40/8 = 5;

4u−5v = (40;32)+(−40;180) = (0;212) is a translation vector of the tiling, & gcd(4;5) = 1;

so this tiling is vertically periodic with least period length 212 length units.

Remark: 212/2 = 106. But 5 cannot be divided by 2, so 106 is not a vertical period length; is it??

● You've changed some «E»s to turned «G»s that aren't point-symmetric figures of «G»s; so I've changed the caption of File:CMGLEE tiling.svg. Please, tell me whether you think this new caption is OK; if so, I'll copy-paste it into the Description section.

● Actually, you've made waves crash on a series of sandy beaches. :-) Coloring your tiling with 4 shades of blue (+ e.g. white for the edges of the tiles) would produce an actual wavy sea! ;-) —JavBol (talk) 18:39, 24 October 2025 (UTC)[reply]

I think the discrepancy is because mine has just two M/W and E/3 in a cell whereas yours has four.

Yes, the caption is good. I've also made the colours more sea-like. Cheers, cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 21:52, 24 October 2025 (UTC)[reply]

@Cmglee:

Ah, yes, you've changed several things in the pattern. The basic translation vectors of your tiling (corresponding to the «sides» of your pattern) are:

u = (10;8), v = (4;−18).

Lcm(8;18) = 72; 72/8 = 9, 72/18 = 4;

9u+4v = (90;72)+(16;−72) = (106;0) is a translation vector of your tiling, & gcd(9;4) = 1;

so your tiling is horizontally periodic with least period length 106 length units.

Lcm(10;4) = 20; 20/10 = 2, 20/4 = 5;

2u−5v = (20;16)+(−20;90) = (0;106) is a translation vector of your tiling, & gcd(2;5) = 1;

so your tiling is vertically periodic with least period length 106 length units, too (indeed). :-)

What about adding these periodicity calculations to the Description section of File:CMGLEE tiling.svg? If so, is this periodicity-calculation paragraph idiomatically phrased? —JavBol (talk) 21:56, 26 October 2025 (UTC)[reply]

Thanks. Done! cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 16:14, 28 October 2025 (UTC)[reply]

Thank you very much, though I'm uncertain which photograph(s) of mine you've seen! cmɢʟee τaʟκ (please add {{ping|cmglee}} to your reply) 02:07, 13 October 2025 (UTC)[reply]

Scribunto's new svg feature

I don't know if you heard but I thought you'd be interested - Scribunto is now allowed to output svgs which are rendered directly in the browser, which means they can use CSS animations.

For example, here is your greeting card.

@Bawolff: Many thanks: that is good news indeed. I'm a happy ~~bunny~~ bouncing character!
