I can listen to you all day. You have a gift to make things interesting.

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.

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!

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!

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.

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!

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😄😄😄💎

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.

Max Born is one of my physics heros Imagine my joy when I discovered that he was grandfather to one of my favorite actresses - Olivia Newton John.

Your videos are simply addictive, Kathy.

She is one of my favorite podcasts this year.

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

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!

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.

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!❤️

I commend you for the background history that you give of these gifted intelligent people of science. It's sad how politics and religion can ruin scientific inquiry.

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.

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.

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

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

I appreciate the deeper understanding and greater perspective I've received about this amazing period. I admire how balance, truthfulness, and heart are woven into every page of your storytelling. My sincere thanks.

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

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.

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

Excellent, I'm an ordinary guy. I stumbled on to this. I have no backing or grounding in any of this stuff, but your presentations are fascinating.

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

Your videos are as informative as they are entertaining. Going trough them all right now. Thank you so much!

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.

When Kathy speaks, you listen. What an absolute belter of a video mate. Lots of love, Kathy. :)

Keep the coming. They're wonderful! 😀

Beautifully presented. Really thankful for amazing experience ma'am.

Must have been terrible for Max Planck to outlive all his children. I believe his son Edwin was executed a couple years before Max himself passed. Found this vid after reading MP's wikipedia page, after first reading that the standard kilogram moved away from being a physical artrifact and is now defined in terms of the Planck constant... got me thinking who is this Planck guy. Really interesting channel. We think we live in advanced technological age. Amazing to think these guys did all this work without computers. Liked, subbed and now I gotta go and watch all the earlier vids

Awesome as always! Thanks for sharing!

Always enjoy your presentations. Thanks

I had just discovered your amazing and really interesting videos. It,s a fascinating period of science and history.

I just found your channel and I love it! Thank you for the detailed history. I appreciate that you include the social/ personal history of these wonderful scientists and mention the brilliant women behind them (unfortunately history seems to put them there). I’m learning! Thank you! 🙏🏻

Thank you so much for this Kathy! Immediately subscribed!!

Love your essays

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

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

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

Your channel content is definitely the type of stuff I like but didn't see anyone focusing on. Gonna sub & binge watch some vids :)

Just discovered your channel. Love your storytelling with regard to the scientists mentioned here. Will check out the other two.

Awesome Stuff!!! It's so enlightening and revealing to learn the small details and stories about the personal lives of such great and highly influential scientists. I Love the videos and I'm learning so much. Thank you!

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.

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

Lovely presentations. Madam. Thank you verymuch

Thanks again Kathy. You have helped provide so much historical context to my undergraduate physics experience.

what a fantastic lecture, I m looking forward to your next video ......

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!

Ms Kathy, where have you been all my life? I am at work and I think today I will do nothing but watch your videos. Thank you.

Thank you! Great video!

Wow, the picture at 18:08 was amazing to read the names of physicists I knew of from high school and college. It must have been a heady experience to have attended.

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.

What a wonderful narration 🎉🎉

Very nice video. Thank you.

Excellent. Thank you for your splendid work

Two videos and you earned a new subscriber.

great review

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.

Incredible information thank you. Keep up the great work! 👏 💯

A wonderful listen.

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.

Thanks again, Kathy!

I randomly stumbled across this video and glad I did. Thank you.

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

Helping with the algorithm, after enjoying another fine episode.

Great job 👍

Very interesting! Thanks!

very good explanation and thank you very much ma'am

Absolutely fascinating.

Great videos, great stories!

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.

Need such stories at the current testing times being faced by all of us. Thank you for telling such an inspiring one.

You make learning easy. Thanks for opening closed doors.

Thanks, Big Time Kathy, Cheers🍷 for sharing your knowledge.

Great video, nice to learn about the lives of people who made discoveries and not just their equations.

I am in my mid60s and have been an armchair physicist/mathematician for a couple of years. Your page is a goldmine. I love the history of quantum mechanics with Max Planck being one of my favorites. He not only was a brilliant physicist, but also a wonderful man! Thank you! and I subscribed to your page. There are many hours of listening for me.

Great historical research ❤️👍

1st time listener. This is fantastic.

Really interesting talk .. thank you

Nice video. Very interesting

Great video ma'm.

Great video great channel ...

Thank you mam for the information i was searching for this type of videos.. Where i got to know about sciencists and their contributionstowards science...🙏🙏

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.

Congratulations. You have got a gift for this. 👏🌹

Thank you madam.great lectur.

Found very informative.

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.

Numero Uno is Maxwell, Numero 2 is Planck, Numero 3 is Galileo, Numero 4 is Archimedes

AWESOME !!!

You deserve more views. That is all I am gonna say.

Hearing this woman, I become a child who listen to stories told by a neighboring aunty. I wish I was young again.

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?

It is deeply moving to have some insight into the tragic struggles face by these giant of physics(and Chemistry).What a shame they had to discover the mysteries of the atom at the same time the world was losing its mind

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!

So cool!

Lovely, really am enjoying these lectures to humanise these theoretical giants... Thanks, dear
