Photoelectric Effect History: A Battle of Einstein vs. Lenard
Vložit

- Einstein won his Nobel Prize for the photoelectric effect, but why? He was more famous for relativity. It all has to do with a man named Philipp Lenard. Lenard's experiments inspired Einstein, and Lenard at first befriended Einstein but then turned and made his life a misery. This is a fascinating story of how a brilliant scientist can descend into madness.

I know you're going to say otherwise, but as always, I consider this WAY too short! I look forward to these so much. Bravo!
Einstein later commented that general relativity, which treats space-time as ... well, a substance, since it can be bent in the presence of mass, is basically the equivalent of an aether. In fact, he didn't see how anyone could conceive of cause and effect without the existence of an aether. Great video, though. Immensely enjoyable and informative.
I'd never heard of Lenard before watching this video. Also amazed to see the physics Nobel prize was subject to much politicking, it's plain for all that the peace prize is.
u failed to mention the part where einstein concluded in a letter to lorentz that the aether must exist.
I studied physics and one of my oldest professors was a German physicist who studied at Heidelberg University in the 30´s with incredible professors. Sommerfeld, Heisenberg, etc. On one occasion he told me that he had an experimental class on X-ray diffraction and the professor who was a fascist prepared a crystal in such a way that the diffraction pattern was a swastika. Probably was Lenard.
You do the history of science great service, bringing to light these amazing stories with scientific accuracy, passion, and great storytelling. I could have written this on any of your videos, really, they're all so wonderful! Thank you.
I wonder if Lenard's Ether was right after all, Quantum Fields by another name and Electrons just folds in those Fields.
Ma’am, I am hooked to your channel. You give out exactly what I need - the story behind the discoveries . I teach physics. The children love these stories and become more receptive to the concept being taught. Thank you from a teacher in India.
Great summary, presented very entertainingly, thanks! Just read about the rise and fall off Lenard in a memoir book. Sad to ruin a career by going head first into fascism and personal vendettas.
She is the Beethoven of physics explainism, whatever that means. I am always astounded that Einstein understood cosmological forces while believing that the Milky Way was the entire universe. You can have only a tiny sample and still decipher the entire structure. She is doing God's work, which is more than He ever did.
People like you are the reason why i love youtube - despite all it's shortcommings. Thank you very much!
Hi, Kathy. I have just begun to watch your channel, and I cannot begin to tell you how much I'm enjoying it, although I guess I just did. In any case, your mixture of story and science really hits the sweet spot in the vast spectrum of physics videos on CZcams. This is great work, so thank you again.
I came across your channel only recently but it has since become my favourite. Cheers!
This is far more interesting and informative than anything I could hope for in a piece about history of science, particularly physics. I love the way you dig into personal, social and historical details to bring up the physics. The presentations are so accurate, entertaining and motivating. I have red so many popular science books, but these videos take the issues into a different realm. Thank you so much. Well done, and please keep up this impressive work.
I just found your videos, and I have to applaud you! REAL, HISTORICAL RESEARCH! I love it! I subscribed after just two videos. Your content is intelligent, informative, based on actual first-hand accounts and publications, doesn't use third-hand cursory "conventional layman knowledge", and I have learned a lot, as a student of history! Ten out of ten, I love it! Also, don't worry about people saying these are "too short", rather, they are concise and give you exactly what you need to know without filler or long and annoying adds. You are doing the world a service!
History is nuts, and you tell it so well over and over, so many things I've heard before but without so many interesting details. Thank you!
Kathy, you are superb!!!!! So much work and research must go into each of your amazing videos. You present them so naturally and clearly, it’s like having a chat with a friend with a brilliant and learned mind! Wow!
Your videos on the history of physics have really piqued my interest in the scientific intrigues and dramas that played out both in public and behind the scenes during these turbulent times of the 20th century. I'm avidly ingesting your extensive catalog. Thank you!
That was really good! I’m happy to have found your channel.
What great depth and understanding the minds involved, so well laid out. Thank you
