You might think that quantum physics was discovered because of some super complicated electron behavior or something, but it was actually invented to explain ovens.

If I heat up a piece of tungsten up to 5500 Kelvin, it should be the same color as the sun, correct? Does that mean the tungsten filament in my lightbulb that puts it's light out at 5500 Kelvin; does that mean the filament in my bulb is 9440 degrees F (5500k)?

So idiot to add a cat image in the video that have nothing to do with what he was talking about there, so I had to step out from this shity interpretation after few seconds.

Considering we're talking about the very laws of nature, I don't think it's terribly accurate to say quantum mechanics was invented. It's more a discovery than an invention. The mathematical language used to describe it could be considered an invention, I suppose. Like most things of any worth, it's complicated.

Good information. My comment is on the presenter. I liked Hank Green's style of presentation in earlier videos. Here, he seems super agitated much like other presenters. Is there a "presenter school"? Go back to your earlier form of presenting. Quantum Mechanics makes the most sense if you think of everything as energy or an energy field.

Quantum physics could have been discovered by the ancient Greeks. It is the obvious solution to Zeno's Paradox. Only God is analog.

Quantum physics is still a mathematical slight of hand. If it doesn’t add up in the real world just add more imaginary particles and their attributes.

You’re getting better and better at doing this. Some ideas to experiment with: 1 slow down slighly 10-15% 2 add a pause between slides to allow folks to grok the conclusion 3 Your presentation has become much less flippant. Try eliminating this altogether. 4 try a summary of “heres what we just learned”-repetition helps 5 eliminate diversions that don’t directly contribute to the conclusion I stopped watching you for a few months, but now I’m going to start again. Keep improving!

this would have been handy 15 years ago when we studied something called "black body radiation" and I had no idea why or what that even is. Only equations. Getting the story behind it makes it much easier to understand and learn.

I vaguely recall that the -1 is the number when particles are indistinguishable. If they were distinguishable, the term would be +1. Therefore we know that ell electrons are identical, as are protons and neutrons, and atoms of the same type. These is no way that we can tag them to identify them at some later time.

What did you say???? 11:40 - 11:45 if one observation dont match with your theory you have to discard the theory ?????? Lets look back..... if some part of the world doesnt match with your theory, than you have to stop finghting reality…. I agree… it should….. BUT why doesnt science do that ???? Like geological where it is factually observed that geological processes can throw up a who lot of dirt and in matter of minutes-hours create whole stratified regions (mt st helens in 1980, surtsey Island in 1963, hunga Tonga Island just recently) it can even create Canyon structures including a river in matter of minutes-hours….. So why does secular science still hold on that the earth layerings world wide took millions of years ???? IT DOESNT observations show other wise. That also means that FOSSILS are NOT millions of years old and explains perfectly why there are LIVING FOSSILS still present..... \so why does scinece NOT alter their theories for that ??? which is SILLY an highly unsciencific.

I know precisely what he's talking about, so I can fill in all the gaps in his presentation. But if I didn't already know it, I can't imagine understanding it from this video. At an absolute minimum, he should have shown a plot of all three distributions for the same temperature, showing how the real distribution switches from one theoretical model to the other. A diagram showing a light ray going through the hole and bouncing around until it gets absorbed would help, too.

This explains why sometimes in my car after leaving my house I ponder the question "Is my oven on, or did I remember to turn it off?" And it is only after turning around and driving back to look at it directly that I know the answer.

You forgot one part of the story: Why did they want to understand the color temperature relation. Well, the first that came to my mind was that they wanted to know how hot the oven was. Who needed that knowledge? The people that baked on emaille on iron pots and pans. That requires a specific temperature.
