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!

People like you are the reason why i love youtube - despite all it's shortcommings. Thank you very much!

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.

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.

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.

Oliver Heavyside would be a great topic of one of your videos. He gave us Maxwells equation in the form we are familiar with.

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 KZfaq. This is great work, so thank you again.

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!

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.

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.

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!

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!

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!

I came across your channel only recently but it has since become my favourite. Cheers!

What great depth and understanding the minds involved, so well laid out. Thank you

Thank you for putting this information in one place. I was aware of it, but your presentation gave an excellent summary in a single well-organized place. When my grandchildren are old enough to ask about it, I will use your presentation as part of their education. Incidentally, one recent history of World War II had a quote that, the reason the allies won the war was because “our German scientists were better than their German scientists”. There was a book called, “Hitler’s Gift” by Pike and Medawar on the benefits to the Allies of accepting the Jewish scientists the Germans expelled. When Erik Kandel got the Nobel Prize I remarked to my children that the gift continued into the next generation. In the end, the discrimination did not pay.

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.

I’m binge watching your videos Kathy! Hands down the most insightful and informative accounts of the history of physics! I’m going to order your book too - I’m sure it’s great also. Thanks much!

That was really good! I’m happy to have found your channel.

Your videos are sooo fascinating!!! Love how you relate the Story behind the science

I really love how you tie together science facts with the people who discovered them, with the general era, how wars, ideology and superstition (prejudice) influenced so many things. I can binge watch your videos for hours, never get tired or bored, even though I mostly know the "science". Or maybe it is because my background knowledge, I am able to binge watch without problems. Hard to tell. Regardless, great videos, Kathy!

Brilliant Kathy. Informative and entertaining. Thank you so much. Fascinating

It is so much easier to remember facts, new words & concepts when they are tied to the people Who struggled to understand them & that is the service you are doing us all dear Kathy. Thank you for BEING YOU. I really appreciate you and your work!

Thanks! Really enjoying your videos!

I love you, Kathy. Your insight into the history of physics is pretty detailed and simply great.

You are great story teller. I will have to watch these videos again, so that I can learn everything explained.

Love your channel. Thanks so much for these videos.

Informative yet entertaining. Well done.

I love your videos which, as far as I know, are unique on youtube.

Great content and delivery!

Excellent video. Very interesting, informative and worthwhile video.

Yes you do have a lot of other videos; I am inundated with them, but enjoying it. Thanks Kathy.

So awesome. I love this channel!!

I learn and get entertained, what else could one want from a youtube channel!

great video. The context behind some of the stuff I teach is fascinating and you explain it so well.

Excellent video, it really helps to learn about the human side of scientific progress.

Awesome story!!! Thanks!!! I loved it :)

Your love of science is contagious!

What a great history! Thanks!

So clear & a groundbreaking discovery.

Great video as always and what a great presentation.

I always enjoy your lectures on the people who are behind the equations. that is part of the story. thank you

Excelent material! I'm absolutely hooked!

Just discovered your channel. Love it so. You are my Guru

Had never heard of Lenard before, but fascinating to hear of both the good and malevolent influences he had on science and the course of history. Thank you.

Excellent presentation! I learned a lot.

Fascinating. thank you!

Wonderful video ❤️ this deserves more views and likes.

Wow, great video. There are not many like you in the world! Awesome!

Thank you Kathy, nice job!

Your videos are exciting and informative!

historical perspective of science well done, Kudos

Wonderful video, as are all your others I have seen!

Your concise but detailed historical perspective has helped me, as an interested lay person, better understand the physics itself, while making it interesting and bringing it to life from the historic side. Thank you!

This is the one the most informative and interesting video I have ever seen :)

Love your storytelling...

Kathy's enthralling narratives bring to life the thinking behind the great discoveries that have given us the modern world. Free on my laptop. I am grateful.

I just find this channel its SOO good

I'm subscribed now, I really like learing about physics and the origins are the most fascinating. Greetings from Holland Kathhy!

Your channel is excellent.

Wow you're amazing 😍🤩 I'm glad I discovered your channel

Amazing video!

Marvelous story, I loved this video

geez, that's fantastic content! I could spend hours listening to you telling me all about it! "You've got a 'subscriber' in me"

I just love it all It's a sad story of Lenard's life..and a lesson for all of us.

Thank you for another wonderful video. It sounds like the “ether” idea would fit into QFT. Peace

It is so great! Thanks!

Nice explanation thanks a lot

u failed to mention the part where einstein concluded in a letter to lorentz that the aether must exist.

Kathy is marvelous! She presents it interestingly!

Such nicely described. Love for Physics 😊

Good job, as usual.

Most excellent! (as usual...thanx!)

Only two minutes in and am already extremely fascinated.

Thanks mam .. for kind information that a person loving physics should know... 🙏🙏🙏

Your the best story teller on the net ! Your No 1

I am discovering your channel too late! These are great videos.

Nice video, thanks :)

very well explained

tq soo much mam , for explaining the Photoelectric Effect History:

The history of conflicts between scientists is extraordinary! Gives you a completely different perspective of being an observer in today's world

great job always！

Another superb video bringing it all to life as you bring the scientists to life. One scientist that I was sad you didn't mention -- you referred to him as a British scientist - is Arthur Eddington. A fascinating and important man. A torch bearer for Einstein (as well as an eclipse watcher for Einstein!). He was no mean scientist either, especially in cosmology. He proposed that the energy of the stars came from fusion, and he was proved right. I wish there was an index of your videos, I can't always find one that follows another. The Lennard story is amazing and I shall have to watch the video again - pure drama. I am learning so much. Thank you.

Your videos are like gem for us physics students. Thanks a lot.

Super video!

Wow, didn't know photoelectric effect has such long and interesting story. Thanks kathy

Thank you !

thank you your contribution

Thanks for Ur information

This is so good I had to log and like with all my accounts!

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.

Great and so we'll presented.

Late to the party, but ... you really hit this one out of the park, Ms. K. Thanks!

You are really helpful

Really amazing .

Thanks Kathy

Brilliant!!!

I chanced upon this series on physics only yesterday which delighted me much. Though I have been student of Indian and Western philosophy, I loved to know something about physical world, where physics came to my help. I am cypher in maths I still could understand theories and their applications. Your presentations are very helpful in knowing history of physics in lucid way. Thanks.

Great video. I didn't know there was that much to the einstien/lenard beef.

I loved your video! Why you don't post a video about Francois van Rysselberghe? He's the father of long distance telephony and my great grandfather too!
