After watching these lectures i really feel science has scratched the surface, there's so much to learn, and thanks to channels like these, we are getting to question again and wonder at the world around us, a trait long lost with childhood!
@ttrestle
I just love how popular this channel is. Many times I don’t understand what’s being talked about but I always watch every vid. Sometimes multiple times.

Max Planck may have never imagined that his constant would be used in 2018-19 to define New/Quantum SI unit of Mass (the Kilogram Kg).

Math teachers: Zeno's paradox is easy. You can overtake the tortoise because we have calculus. Quantum Physicists: WE DONT EVEN KNOW WHERE YOU ARE
@KahnSkins
Im a highschool graduate with no schooling in Quantum Physics but I Have a real passion for it and these videos are absolutely fantastic! I was never good at math but I understand the theories very well!! love these videos!
@Woodmakerstudios
I love watching PBS, it makes me feel more intelligent than I am.
@MaBuSt
I'm a PhD in Materials Science. I also had a phenomenal Materials Properties course as an undergrad. This was still one of the best ways of diagrammatically showing the origins of the UV catastrophe (at 6:43)
@douglasstrother6584
Planck's approach was to analyze the entropy of blackbody radiation as a function of energy. To make both high-frequency and low-frequency data consistent with the Second Law of Thermodynamics, he included an additional "guess" term proportional to the frequency (hf); this results in Planck's Law. Planck's subsequent application of Boltzmann's Statistical Mechanics to justify his guess then led to his revolutionary conclusion that the material of the walls emit and absorb radiation in discrete quanta. A paper titled "Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler (7/25/08) gives a nice discussion.
@MrGyulaBacsi
Although it might sound exaggerated IMHO, this "math trick" was the single most important moment of the entire history of Science.
@EchoL0C0
I feel like this video doesn't give Planck enough credit. Trying out lots of different ideas to re-create a distribution is not the same as mashing random buttons. For one thing, all buttons have a chance of getting pressed, but not all ideas (such as dividing the whole equation by 0) are valid. Also, it makes coming up with all these ideas sound a lot easier than it is. Lastly, his result was caused by trial-and-error, not pure random chance.
@BeCurieUs
There have been a lot of great episodes here, but this one is by far my favorite. I like hearing the history of the math and scientists as much as the science. The story about Plank and him going "huh, try this" was really fun. And I really like the integration of the tortoise analogy with BB radiation and Plank length. Everything just worked for me :D
@Moonbo
Damn I love this channel!
@jackhill2765
Thank you for (1) a clear, concise and comprehensive explanation of exactly what the "ultra violet catastrophe" was and how reformulating conventional wisdom (the Rayleigh-Jean Law) by incorporating Plank's constant to form the Plank Black Body Law, quantized the relationship between frequency and energy, resolving the issue, (2) for confirming that the flaw in the Rayleigh-Jean Law was fundamentally the same misconception as that leading to Zeno's paradoxes, and finally, (3) for tying it all together by showing how the fallout from Plank's idea essentially resolves both issues not to mention giving birth to QM. I also appreciate seeing the actual Rayleigh-Jean Law & Plank Black Body Law. Understanding the history is a necessary first step toward understanding the result. Extremely well done!

"I'm glad we could help you guys get entangled" Keeping education Classy. Thanks, that made my day!
@MooImABunny
"I'm glad we could help you guys entangled" holy crap that was the most wonderful geeky thing I've heard in a while XD
@BoomBrush
That moment at 9:40 was a "lightbulb" moment for me. The explanation is amazing here, well done with the video!
@SayyadinaHeresy
Thank you so much, PBS Spacetime for these videos on the quantum realm! They are so clear and concise! I'm very much enjoying these!
@bdz_4206
The BEST episode. Never fear being silly!
@abundantsoul6487
i am so grateful to god that he made me stumble on this channel . as i am an indian student the people from my country who create videos on this stuff are all occupied by JEE , NEET AND CBSE no one is interested in science rather all r interested in marks . thank u for this beautiful explanation
