Quantization of Energy Part 1: Blackbody Radiation and the Ultraviolet Catastrophe

So we know that physics got turned upside down at the turn of the 20th century, but how did that all begin? What was the first thing that set this whole chain of events into motion? Well it all started with Max Planck, blackbody radiation, and the ultraviolet catastrophe. Gather round, children. Let me tell you a tale...

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Your intro alone just made me so happy.

[Ahmed-hdlr]

i’ve always been mesmerized by scientists discovering such a revolutionary thing as Planck did. as it said in the video he didn’t believe his own discovery but imagine how incredible it’d feel to literally discover how one of the fundamental things about the universe

Professor dave i have had two professors explain this to me and your explanation was the only one that actually made it into my head. Thank you!

[debanjali]

Dave Ghrol made me pass all my topics in physics! THANK YOU SO MUCH!

[brian_mcnulty]

That shit you just said about the quantization being multiples of such a small number just blew my whole world apart.

[sphanie]

this is weird but why do i get so happy when i finally understand a physics concept?? this is only part 1 and i already feel like i can answer my exams hahhaha

[rinnegansr]

your pace of explaining anything is perfect.

[leonard]

Your description on the quantization of energy is nigh unparalleled, even a kid could fully grasp it from this, so much sense hit me on the topic after watching this.. things I had initially took for granted and never really understood on quantization make so much sense now, its almost crazy, the whole thing on the miniscule scale/nature of quantization being the reason why it was overlooked in the classical approach of black body radiation calculation is crazy, thanks Professor Dave...

Jolly good, this is. I am taking a course in modern physics starting two weeks from now. I knew you would have something for me and boy am I excited for this youtube series and this course after watching this video.

I have never ever come upon an explanation of the Ultraviolet catastrophe, and thereby Planck's equation, as clear and concise as this one.

[alexshanto]

I watched many videos and thought for hours. But I couldn't completely understand the concept that you make clear in 2:10 -2:30 seconds. Thank you so much. You are awesome.

[backstrapped]

This is the best explanation of quantisation i’ve ever seen.

[I-STEM__]

you are the first one I approach when I have to learn a topic.Thank you so much Professor Dave.

[sharminabadi]

i love you so much for making this playlist😭

[lancelovecraft]

If I start a shoegaze band one of the album's will be named Ultraviolet Catastrophe

[Kni]

Why I did not find you in the past 29 years of my life. Awesome !

[estebanjara]

he gastado bastante tiempo buscando un explicación clara de la catástrofe ultravioleta, y este ha sido el mejor video que he encontrado hasta ahora. Gracias!!

[samanthadaniels]

I am currently in the last leg of my schooling to become an x-ray tech; these videos have helped me understand the more drawn out parts of radiation physics than any book that I have paid hundreds of dollars for. thank you so much!! and please keep making these videos

[albirtarsha]

I am so happy that I could share this with my son! Thanks Professor Dave!!!

I heard somewhere that Planck just got irritated with the math and introduced h as the minimum energy value, fully certain that h=0, so that classical mechanics would still work and minimum energy would still be 0. But later in the calculation he saw that h has an actual value, and not just 0
