Another winner! Thanks for sharing these videos.

[@calebindiatsi8781]

I really love your videos. As the names of the great scientists pop out of your lips, it brings back vivid memories of life in the engineering lecture halls during my study at the university. It is without doubt that the first half of 1900s seem to have been a period of great revival for the scientific community, and academic institutions played a great role in supporting and nurturing science. By weaving together the discoveries, the scientists, the places, the events in history and throwing in bits from their personal lives creates a flow that is very pleasant and easy to follow. Thank you.

[@bishakhbhattacharya5858]

Dear Dr. Loves, the experience of going through your lecture is simply overwhelming! Please continue with this effort and let us relish the great renaissance period of Physics.

[@Kathy_Loves_Physics]

Thank you so much for your kind words (it took me like 30 minutes to determine why you called me Dr. Loves but now I …. love it!)

[@markredman581]

Isaac Asimov History of Discovery introduced me to the enthralling combination of scientific discovery combined with historical biography. Your series is youtube equivalent. Love your content, enthusiasm, and graphics, Kathy. Keep then coming!

[@vishank7]

This is a piece of absolute beauty! The stories are amazingly interesting and also help form a much stronger bond with the equations we learn. Just awesome! Please keep making these videos ma'am😄😄😄💎

Thank you so much Philip for the lovely compliment

I had a 30 year career as a Biochemist and Biologist and Research Scientist in both Anti-Cancer and Anti-Inflammatory drug research. Worked on IgG Monoclonal Antibodies for 15 to 20 years before bringing one to the Pharmaceutical market place. I had taken some Thermodynamics and Quantum Mechanics in College as a Chemistry Major. It was very difficult. I have recently enjoyed studying Hubble and his Astronomical work in the USA in the 1920's. Now, your Physics and History lesson, of all the Seminal leaders, in Europe, during this same time period is most fascinating!

[@shannonirion5234]

Comment repeated from my account on Reddit, where I originally found the video: This was a really interesting video! I didn’t know most of the history behind these different ideas proposed by the prominent scientists of the 1910s-1920s. Thank you for the new information and the clear way you explained it!❤️

[@Kathy_Loves_Physics]

And thank you for commenting in 2 places!!

[@allenciuffo7576]

I like your enthusiasm best, no I like the topics best, no it’s the detail, or maybe your ability to bring these foundational scientists to life and place them in their moment in history… I must ponder.

[@lentilreflection2676]

Wow! Great video. Thanks for sharing! Looking forward to watching more of your stories.

[@Kathy_Loves_Physics]

Glad you liked it

[@h2energynow]

I find the ability to download the words using the three dots or show transcript increases my appreciation of what is said. Awesome lecture.

[@Kathy_Loves_Physics]

I’m so glad that helped. I watched a lovely disabled woman on KZbin and she reminded me that every KZbin video should have captions as it only helps people and so I’ve been trying my best to make sure everyone of my videos has captions to it.

[@Zamicol]

Kathy, I'm back re-watching your videos. You're amazing!

[@timjohnson979]

Kathy, I read so much about these scientists back in my high school and college days. That was 50 years ago! I'm really enjoying your refresher. Most of what I learned back then was the straight science. Only George Gamow brought out the personal lives and interactions back then in his books. Your doing the same today should inspire us all.

[@Kathy_Loves_Physics]

Thanks Tim.

[@matthewhoag2609]

I’ve known about all of these people through my studies, but not like this! The connections, the relationships, and all of the personal circumstances have such a big part in how thing played out. It makes me wonder what it would have been like if Plank hadn’t helped keep German research alive during the difficult years around WWI. You really make it all come to life. Another great video!

[@chicolofi]

Your videos are simply addictive, Kathy.

[@Kathy_Loves_Physics]

Glad you liked them

[@fredeberlein]

A marvelous presenter! Nothing better than listening to a person who knows their subject. New and interesting insights into people and events. I thought I knew all about them. I didn't.

[@halloweenlisteningparty]

Hi Kathy, I don't have much of a science background, but I have a growing interest in radio, and how things work behind it. Your lectures are great, and I think it would be brilliant if one day you could turn them into a book. That would be something that I am sure people would love reading, thanks to your biographical descriptions of how all of these scientists got on, and worked with each other. You also make it easy for people to understand.

[@Kathy_Loves_Physics]

Funny thing, this all started as a book about the history of electricity (which morphed into a separate book about the history of Quantum Mechanics as I was trying to describe LASERs)! If you are interested in being a beta reader of my book on electricity (a reader who tells me what they think about a book before it is published) send me an email with a subject "book" and I will send you some Word files! My email is in the "about me" section. Cheers, Kathy

[@halloweenlisteningparty]

@@Kathy_Loves_Physics Thanks very much Kathy!

[@CharlesAustin]

So amazing to hear how all manner of scientific developments occurred .. fabulous videos ..like a book we can’t put down. !!

Bravo, this description of history where science, human friendship and life tragedies merge is pure music... Thank you Mme Kathy

[@martifingers]

18 minutes of enlightening material. The mix of history and science is just perfect.

[@jmcargal]

You are magnificent! Wish I had discovered you earlier but am making up for lost time.

[@docforest4851]

Kathy, these videos are of great significance. I can’t help but look at these and see the lessons imbedded in them, if people would only listen. History repeats itself, unless we learn from history.

[@pirminborer625]

Absolutely bluffed how you can tie up all those events and make it such interesting to listen. I love physics and now history too. Looking forward to many new stories.

[@Kathy_Loves_Physics]

Thanks 😊

[@pablotrobo]

im glad i found your videos. They are clear and detailed at the same time. Great contribution to science education

[@Kathy_Loves_Physics]

Thanks

[@Thecaptainblackadder]

I often wonder if people in 1920s realised the importance of these discoveries. Was it that these scientists became famous after the atomic bomb or did normal people realise the gravity of the discoveries before that? It would be good to make an episode on that.

[@terriblemvh]

She is one of my favorite podcasts this year.

[@harrybarrow6222]

Kathy, I really love your excellent videos. I am a Brit, living in England. My bachelor’s degree is in Maths with Physics, from Cambridge - almost 60 years ago. We had some remarkable Physics lecturers back then; I recall a course given by Otto Frisch, which included the story of the discovery of the electron. One of my favourite text books was by Max Born. Back then, I was not much interested in the history… but now I am VERY interested in it. I am retired now, having worked for 40 years in AI research, 14 of them in Palo Alto, Ca. I am very glad to have found your channel. Thank you for all your hard work in making these videos. Please make many more!

[@sam21462]

I recently discovered your terrific videos, thank you very much for treating us to these wonderful stories!

[@Triniti1VDO]

Kathy you're wonderful... I started watching one clip abouyt electricity so I could understand better it's usage.Since that I just can't stop ! I am not a physicist or anything close to a science buff (I am a welder).. But I really enjoy your way of compiling all those figure larger than life who transformed so much of the appreciation of the world we have today. So has the birth of all those theories so vital in all aspect our day to day lives. Thanks!

[@rsfaeges5298]

My fave of your videos yet -- which is saying something!!

[@mnada72]

You are so great story teller, I can listen for hours 😁

[@yzScott]

These are great. I've largely watched topics I am quite familiar with. The accuracy has been super and the presentation clear and interesting. Real physics, real history, and not over-simplifying into meaninglessness. Thanks for producing something I can share and recommend to curious non-scientists. And 15 or 20 minutes at a time isn't a giant commitment. These really capture the spirit of some of my favorite layman-accessible pieces of real science in a bite-sized chunk. That's impressive. The kind of things I'm thinking of: Feynman's "The Character of Physical Law" lecture or Darwin's "On the Origin of Species" or the old "The Strange Story of the Quantum" even Feynman's "QED." I recommend all of those things, too. But they ask a lot more of the audience.

[@jw228w]

your enthusiasm and gift of presentation on often vague ideas in science are amazing.love to here about these great men and women of yesteryear.too bad here in US we dont get the background that led to these scientific principles. john

[@Kathy_Loves_Physics]

I am so glad you liked it. Max Planck is particularly fascinating isn't he?

[@franklinshouse8719]

I really enjoy your videos. I'm a radiologist, but I have never studied the history of radiation and quantum mechanics in depth. Thanks for the lectures.

[@DerPlasma]

Really nice video! I was surprised how little I knew about Planck after watching your very well made video^^ I'm wondering if you are planning to make similar videos about more researchers - I would love to see one about Heisenberg for example.

[@Kathy_Loves_Physics]

Glad you liked it, I am planning to get to Heisenberg eventually but as these videos are based on books that I’m writing and I want to finish the one on electricity before I work much more on the one on quantum mechanics I might stop working on the quantum mechanics for a little while and go back to electricity with a story of the invention of television. It might take me a long time to get to Heisenberg sorry.

[@Kathy_Loves_Physics]

Obviously, that is my view too

[@eigenchris]

I'm plowing through many of your videos and enjoying all of them. I've tried reading Heisenberg's original paper on the introduction of matrix mechanics, but I find it pretty incomprehensible... which leaves me pretty depressed because it makes me feel like I'll never understand how quantum mechanics was discovered. I don't suppose you know of any more "reader-friendly" versions or guides for understanding Heisenberg's work?

Many physicists seem to think that Heisenberg's uncertainty principle is at the heart of the "strangeness" of quantum mechanics. But, in reality, it only expresses what Jean-Baptiste Joseph Fourier had already explained in comparing measurements in the time domain with measurements in the frequency domain. Just as these two domains are linked through the dependence of frequency with time, the domains of position and momentum are similarly linked (momentum is the derivative of position). The mutual limitation of precision described by Fourier is the same reasoning behind the mutual limitation of precision described by Werner Heisenberg. It is simply a limitation on being able to measure the position and momentum of a particle simultaneously; it is not a claim that either position or momentum ever is lacking a precise value. So the uncertainty principle is independent of the "mysteries" of quantum mechanics, only becoming more significant at small scales due to its being easier to observe there.

[@richardfoster2895]

Kathy, I love your series. As one with an MS in physics the history of the developers is fascinating. But allow me one small word of constructive criticism. You mentioned the auger effect. It is NOT pronounced as it is spelled. It is pronounced like O.J. oh-jay. At IBM we had equipment that did Auger surface analysis. Lots of peers misspelled and mispronounced the term.

[@deanschulze3129]

It's worth mentioning that Germany's invasion of Belgium led to George Lemaitre and his brother enlisting in the Belgium army. I've often wondered how many other potential geniuses never got to do their life's work because war ended their lives.

[@bitjockey6265]

20 years ago I read "The Making of the Atomic Bomb" by Richard Rhodes. I was hoping to learn about the science. Instead, the book discussed at length the political and social forces that shaped the scientific landscape that influenced the research and discoveries that resulted in the making and deployment of the bomb and its repercussions. A fascinating history that I highly recommend. (Yes, the book did give me the science and technologies of the bomb that I was hoping to get in great measure. Which is why it is 700 pages!) Your many videos revealing the personalities behind the science compliment and embellish what that book started. Thank You!
