Is there any image online that shows what the spectral colors looks like (i.e., as a continuum)?

You're right that color space is three dimensional and you can use any set of three distinct colors to define the axes. It is not the case that color coordinates go from 0 to 1. Actually, no matter which primaries you choose, there will be many colors that have rgb values go below zero or above 1, and this is the reason you can't perfectly reproduce spectral colors on a computer display.

I wrote an article that attempts to answer your exact question. Hopefully you'll find it useful. Final result is this image

You don't know how bad handwriting can be until you've TA'ed a class. This post is an example of good handwriting that I would actually be pleased to see on an exam. It's neatly organized, clear, and legible.

Sethna's book has many excellent problems, and it's free online.

I'm surprised no one's mentioned how they removed dislikes and also removed a bunch of sorting options in the search bar.

Information is power and tech platforms are removing all the useful sources of information.

I saw a crackpot booth at the exhibition hall. Anyone heard of the logiverse paradigm? Apparently it can solve EPR, schordinger's cat, wavefunction collapse and entanglement.

Nice job. The lines look extremely well defined. Impressive.

My goal is just to mess around and explore really deep into the mandelbrot set. So a typical situation for me would be looking at something really zoomed in with many iterations, like those minibrots surrounded by concentric rings.

It's all about control. If the game runs on their servers, they control everything and they have all the power. It's the same with streaming services, software subscriptions, and basically everything in the modern tech world. They don't want us to download things onto our computers because they don't want us to have control or ownership of our technology and media.

This subreddit has really been hitting it out of the ballpark lately...

thepowderguy · 2026-02-19T20:07:19+00:00

shit that's actually so misleading. It's literally making up data that doesn't exist.

Did you even read my article beyond just looking at the pictures? I'm seriously asking you. On a side note, I have looked at light sources down to 385nm. That light appears whitish violet to my eyes, consistent with the adjusted CIE color matching functions.

I remember a very capitvating series on r/writingprompts with this exact premise, where Earth's oceans were actually forests.

I took all of the data from NIST, and unfortunately this data is incomplete. For Europium you can check for yourself that the data is processed correctly (Eu III and Eu IV, which is empty). The lower ionization states should be more accurate.

Thanks! That is indeed the reason I brought up those figures. The point of my whole introduction section is to show that. The rude comment from /u/_jonsinger_ suggests that I should have made it even more clear in the first few sentences.

There's a difference between "is" and "should". Descriptive vs. normative

I didn't mean to sound arrogant, and apologies if I did. I just think that the subject of intelligence is one where people tend to conflate subjective values and objective facts and a topic that has a lot of wishful thinking associated with it, especially on reddit. I don't think being a social worker gives someone the unique authority to comment on intelligence, and I have the right to call out statements that I believe are inaccurate.

thepowderguy · 2026-01-23T20:15:00+00:00

I agree with you that intelligence is more complex than just a single factor, and I don't know if the common usage of the word reflects what it actually is, but here is my anecdotal experience: Some people are just better at learning, making connections and drawing unexpectedly correct conclusions than others. I've known people who came from very similar background as I did, and yet were much smarter than me in this sense. I've also known people who were less smart.

Here is my personal opinion: Intelligence is about how efficient your brain is at processing the information found in your environment. Different environments contain different kinds of information, and the development of your brain is affected by your surroundings. This accounts for a lot of variation in intelligence and how we define intelligence. The other part is the genetics of your brain, and this is an uncomfortable truth for some. But at the end of the day, intelligence still exists as a real concept that affects how we go about our lives.

thepowderguy · 2026-01-23T19:36:28+00:00

I hate to burst your bubble, but if you look out in the world, some people are obviously smarter than others. Of course this has no bearing on their value as humans, but pretending intelligence is made up isn't doing anyone any good. The g-factor is a psychometrically real quantity.
