Max Planck Quantum Theory

In 1900 Max Planck accidentally created quantum theory. Why? In this video I use his *own* words to describe one of the most radical acts in all of science.

I've now watched this video several times and I really like the connective threads of research and theory that are made. I don't feel completely satisfied but am waiting for the next installments. It's such a cool story.

It is remarkable how Planck, being an old school physicist, went against his own ideology and stood by the facts. This is pure integrity of character that you find in Planck and Einstein, both didn't liked what they found out but kept to the model that was more adequate to the experiments.

I wish Physics professors were more like you Kathy. For me it''s not just about the theory and the math but the history around the motivation and the how things were discovered that makes the whole thing interesting. Please keep up the great work!

Kathy is a wonderful teacher explaining the most important discoveries which are sadly unknown to most our population.

I'm a retired engineer so I took the Physics series of classes in college, but these videos sure expand on and include some great historical perspective to the subject. Thanks!

I just discovered your channel and I like it very much. The blend of physics and history is so important. Ideas don't just appear from nowhere. Keep it up.

To me you are a modern Jane Marcet. I have watched and liked all your videos and I find them original, entertaining and very instructive.
I admire your generosity for putting so much effort on finding, reading original sources and coming up with such an original script, the result is spectacular, it is the best YouTube channel on physics.

How could I miss this. You are very good at explaining and the history as a part makes me feel happy

[xero]

Love your videos Kathy :)
I'm an EE by trade but I love watching these so I can reaffirm my understanding of electricity, and learn some more history that wasn't taught to me in school.

4:21 Small jokes like this one is what gives your channel that extra spice, love it.

First time I understood these connections.
Thank you,

Great video!, I actually found a coin when maybe 23 years ago in the dirt one day turns out it is an old Prussian coin with Max Planck on one side and the Prussian eagle on the other, I was going through some old stuff and it led me to this video I've done my own research into quantum mechanics and I had no idea I had a coin with Max Planck on it for all these years

Kathy: This is a Really Spectacular midrash on the nature of "things..." Many thanks!! 🔥 ❤ 🎉 😊

I’ve watched several of your interesting and informative videos now, and am a new subscriber. You have an engaged and inquisitive mind, and your enthusiasm spills over in your research and presentation. Thank you so much for sharing!

You give delight and familiarity to a very difficult topic. I look forward to your other programs, JD

[johnrendle]

Fabulously entertaining and educational. Quirky and fun and good. Very, very good!

[johnlinley]

I am still aghast. Plank wrote Boltzmann’s equation. It will take days to accept this.
And as always, your voice is perfectly suited for the history of science. Pure fun.

Nice explanations. Thanks for putting patreon plug at end. Many others put in beginning before viewers have chance to assess if even like, wasting time. If there is interest it is peaked toward the end if done well and more receptive timing.

[CARLOSSAA-yf]

Great video with excellent content. This was my first viewing of your videos, now it is time to check another of yours. Blessings.

I really love your channel. I hope a lot more ppl will watch this, as it is both history and science which gives a better feel of how the science and ideas evolved and how they were related. This channel deserves multi million subscribers! On to the next video!!!
