Like' Bohr's quantum theory, Kathy's retelling the story is a masterpiece. It has everything: romance, disappointment, characters larger than life, and then triumph. Outstanding!
this is absolutely lovely - I really like the description of Niels Bohr, as the mumbling dane - I once worked for his son Hans Bohr (he was a orthopaedic surgeon ) He looked like Niels Bohr and talked like Niels - it took me 9 months to understand when he actually made a decision - as he would keep talking aloud about his thoughts - I thought the secretary was runingbthe ward, but she knew him better and understof when he actually had made a decision - even though he later would mutter his doubts about it.
That is both fascinating and hilarious. I read an interview with Niels Bohr in the 1960s (I think) and it was like doing drugs. I can imagine his son was the same. Ha.
These videos are absolutely magnificent! It brings me back to my high school and college days where my instructors overwhelmed me by the sheer beauty of science. Thanks, Kathy!
Quite honestly, your content is some of the best material I have ever encountered. It's fresh, with compelling stories that delve not only into the nitty-gritty of the physics but that also brilliantly tells the history and human story behind that physics.
Kathy, I love science, especially physics, and enjoy their history. I am mesmerized by you - so beautiful, smart, and energetic. I studied math, chemistry, and physics in college. I, also got a degree in accounting to improve my job prospects. I had a good 40 year career in business but now that I’m retired I’m indulging my passion for science. I’ve watched hundreds of videos on math, engineering, and physics. There are a lot of great presenters on the internet and you are among the best!
Many thanks Kathy, not just for another great video but for one of your best to date! What a fascinating time for physics when Bohr took that fateful leap from the sinking lifeboat of classical science wearing only the lifejacket of faith into the quantum sea. Also, thank you for introducing me to the amazing Williamina Fleming. I was overjoyed to hear that you will tell us more about her in the future!
I think this is my best video (so far) too. Like the "lifejacket of faith into the quantum sea". Yeah, I am super happy about meeting Williamina Fleming and am excited about learning more.
It's hard to express how watching your videos rekindles an intense excitement for the sciences. Chemestry, physics, and electronics are topics of great interest to me. Math, and specifically my lack of experience, is the barrier between us. History appears to be the bridge allowing my excitement to cross. Watching this video I caught myself planning, "how should I finally finish memorizing the basic products? Flash cards? Yes, a flash card app and a schedule. I should research this."
Having taught for 42 years in a high school I taught Math and Science in various grades. Now, why is Kathy's approach not used in the curricula? Because the leaders do not get what real teaching is about. Kathy, your presentation should be used in secondary courses. When I substitute teach, I am telling, in a nice way, teachers to incorporate your videos. Great series of TH-cam programs!! Cheers
Our teachers only have time to teach kids how to pass standardized tests. The material educators are given contains very little historical material. Our education system is after quantity over quality.
"Why is Kathy's approach not used in the curricula?" Because they use SANE PEOPLE to teach school - people who know WHAT TO DO WITH THEIR HANDS when they open their mouth(s).
I fully agree with you. I think that if we had Kathy's approach on physics teaching on high schools, we would have more girls going into science and engineering areas... The world needs that!
It’s not used cause 90% of teachers don’t love their subject let alone care about it. I’ve taught at a lot of schools and very few teachers ever want to talk about physics stuff with me. I’ve even been told by department heads to stop talking about work stuff (physics, physics history, challenging problems, etc) at work dinners.
This story could have been boring (no pun intended) but with your exuberance and flair it was an exciting adventure. I am so happy you make these videos, they bring physics history alive!
Thank you for a most interesting story! I would like to share a funny anecdote about Niels Bohr I happened to read somewhere; While on vacation in his summer house in the North Zealand countryside, Niels Bohr was visited by a journalist for the purpose of writing an article about some of Bohr's achivements. When the interview was over and the journalist was about to leave, he noted a horseshoe hanging over the doorway to the summer house. He then asked Niels Bohr how a man so deply rooted in the natrual sciences could believe in such nonsense, i.e. that a horseshoe is supposed to bring luck if hung over a doorway. Niels Bohr dryly replied: "I have been told that it brings luck even if you do not believe in it!" Thanks for a great channel!
Hey Kathy. Another great video. I’ve been fascinated by particle physics, quantum physics and astronomy for years. Your videos are clear, concise, and rigorous, yet understandable. I love that you present things in a historic context. For some reason, it makes them much more interesting and easy for mr to comprehend. Keep up the good work!!!
Thank-you for this. Your enthusiasm is wonderful! Presenting the story of the atom as a historical narrative is very helpful. Bohr (and Rutherford, Planck, Einstein, Thomson etc etc) were all so fascinating individuals, never mind their science achievements. I can only imagine having a dinner party with them all, or having a lunchtime conversation with them at one of the big Solvay conferences. Actually, if I was at one of those conferences, I would just close my mouth, and sit back and enjoy what they had to say.
Though being just an 80's romantic comedy, look up the Hollywood title 'I.Q." featuring Walther Matthau, Megan Ryan, Tim Robbins, Stephen Frye. You might just get that dinner conversation, after all.
Nice , THOUGH you cannot tell me I cannot ask , although I cannot tell you that you cannot tell me that I cannot ask , and of course you cannot tell me that I cannot tell you that you cannot tell me that I cannot ask .. see you next time !
She is really doing it. She taught Physics in a public high school, and now she's teaching the world the physics and the history together which makes it so interesting, and so easy to understand. Kathy, you are the greatest!!
When you can feel a burning desire or passion for telling a story it can only be good. And if you just know how many shows I see about physics/ science in general I would have wished that information was available ( that easy) when I was young. But anyway I’m so happy I can get so much knowledge just a click away. Happy new year and sincerely thank you. 🇩🇰🎸

Kathy, this video is beyond great. I am 70 years old. I first read about these and related ideas when I was about ten years old, in George Gamow's book "One, Two, Three, Infinity." You have presented here the best elementary description of early advances in the theory of atoms that I have ever seen. Bravo! Three cheers!
@@Kathy_Loves_Physics Your videos remind me of some of the stories of great artists and their interplays, for example, the revolt of the Impresionists which took the core, like 30 years before wide acceptance,
This is a WONDERFUL TH-cam video explaining how the theory of Quantum Mechanics began and how the scientists of the time reacted to it. I especially liked the way you walked us through the way Niels Bohr, in his own words, derived his QM equations and his reasonings behind them. Love your videos, the history, the commentary and the flow.
Found this from your post on reddit and I absolutely love the video! It's fascinating to hear the story behind the theories, to see how it all took time and collaboration, and the controversies. Also thank you for highlighting women as well! Will be watching all your videos soon
@@Kathy_Loves_Physics TH-cam played one of your videos as a random next up. Your enthusiasm and presentation of the behind the scenes journey of discovery are engaging. Great job! I bet you're going to get increasing organic growth as people tell friends.
Hi Kathy. Many years ago I read a book called The Cosmic Code, by Hienz Pagals. You are the first YT'er to achieve such clarity for someone like me; not trained in math nor in physics, but deeply interested both in the concepts, but also in the lives who bring us this understanding. Well done.
Never found myself falling in love more and more deeper than today with physics and chemistry and history. I hope I can radiate this pure passion and energy to my entire students.
Kathy, thank you so much for all of this information, I'm a studying electrician in England, you've helped me understand enough about electricity to realise that I'll never understand! I love your videos and your passion for the subject makes it so enjoyable to learn. Thanks again!
Excellent presentation. I am really enjoying your videos on the history of physics and its related mathematics. I think that I will end up watching them all. Thank you for your good work.
I LOVE this. Also love your other videos on Heisenberg and your general storytelling style. After watching Oppenheimer I find him, Heisenberg, Bohr and all the famous theoretical physicists of that age so interesting. How they were so brilliant, how they disliked each other's theories, how they lived through WW2. 🙂 On a sidenote, I'm personally really interested in theoretical finance (models and such) so now I wonder if there's something similarly interesting in the history of finance and its famous researchers. 😁 But seriously you're such a good storyteller! Just amazing! Also, your video description is perfect :)
Your videos are amazing! I've been binge watching the content on your channel for a few hours now and your presentation is very good (despite the need of a little audio editing).
What a fascinating, entertaining, and delightful lecture on the history of the birth of our modern understanding of the atom. Thank you so much for your presentation.
I've read books (well, okay ... I listened on my phone to books being read) about the history of discoveries in particle physics and electricity during the 1800s and early 1900s, and I absolutely loved them. Kathy's video here focuses on a portion of what those books covered with added information that makes learning about this subject so wonderful. Thanks, Kathy.
Kathy, thank you for your very nice presentation. Such details cannot be found easy about these giants in science. It happened that in 1958, I bought a book "The Atom a Giant"" written by Karl Bohm and Rolf Dorge" translated from German language to Romanian language. Since than the atomic physics is my second passion after Organic chemistry. I noticed your books from your shelves in the background that looks like my books in one of my pictures. CONGRATULATIONS!
Hi Kathy. I do not have a formal education in science but I love it and am always in the look for information. I am writing a blog about the Solvay Conferences and looking for information I suddenly came into you and I am thrilled! This was really interesting and I want to thank you for doing this. I'll be following you from now on. Thanks again. Your enthusiasm is contagious.
I am so happy I've found your programs on TH-cam! I'm very old and, thanks to you, have become engaged in recovering lost math to better follow your talks.
I am so thrilled to have found your channel and am treating myself to one of your videos each night. My background is Oxford Chemistry. Research: Free radicals in solution. Mind boggling!!!!! Well ......Anyway I have long known the sequence of arriving at the planetary model - and have read acounts in both popular and academic works. However, your video is far and away the clearest, the most memorable and most entertaining of them all. I love the way your bring the scientists to life in your videos. I have always believed that science from Michelson Morley to the first atomic explosion is the most fascinating and wonderful story in history. If only there was a Shakespeare to turn it into a 'History Cycle'. One legendary genius after another. For a while scientists were that unpolitical, free sharing band of brothers they all believed in. How sad that today scientists often have to hold their tongues or lose their funding. Sorry for rambling on, this was just to say GREAT VIDEO
My last dose of formal physics education was in my Paleolithic period (AKA: a public high school class near Chicago.) I pursued a humanities degree in a small college . . . but I now revere everything I am learning about Prof. Niels Bohr. Kathy is a wonderful science history teacher!
Hi Kathy from New Zealand. Recently subscribed to your channel and been watching your vids, which are very interesting. Back in the early 1980's me and my brother were deeply interested in studying Physics and Mechanical engineering in the US. At that time we were living in one of the Gulf states and had travel restrictions so sadly had to shelve our science education plans. Physics is such an interesting subject and I totally love it and can relate to your videos. Cheers!
Hey Kathy! I am an old science teacher and I just discovered your videos the other day and have used a couple in my lessons. I'm a big fan of science history. Great story telling!
Thank you so much for such an amazing video! I just started studying quantum physics and am amazed at the personalities involved, the upsets, the rivalries. What a fascinating time to be a scientist! Brief tidbits and anecdotes included in textbooks about some of the history were not enough for me and I stumbled across your channel to find more. You deserve so many more subs. I love how thorough your treatment is of Bohr's life and also appreciated learning about how important many women were in the direction of developing and also challenging the Bohr model. The story of Felming is also very inspiring. Next video I watch will have to be on the great Bohr-Einstein debate.
When you are talking with such enthusiasm it lightens the room. Thanks for all the research you have done and for revealing all of this. I never knew anything about the back story. Fascinating.
I really loved your chat. It enlighted me about the importance of Bohr's model considering I'm not physicst nor chemist. You made it accessible and understandable. Thanks a lot
Soooo much in each episode. I have to break each episode down and investigate the topics being discussed. You are such a great teacher! Thank you so much for creating these videos.
Hi Kathy! Im one in the wave of new subs. Only found your videos 2 - 3 weeks ago. Yesterday I went to your channel to find more vids only to discover I had binged your whole library - 2. Several I had watched more than once. Not as background either. Full attention. Maybe its a gooid thing the algorithm waited awhile to show you off. Let you build your library and tune your skills, before the whole world came to your door. Thank You so much. Your love of the material is just infectious. ... Stay well, now that your recovering. :)
I really do think that I had the best of all possible timing (aside from getting breakthrough COVID 😩). I have been told by several people to produce shorter videos more frequently and on a regular schedule and… That’s not what I want to do. These videos take time and I want to have enough space to really explore and deal with depth so I’m very happy that I’ve gotten more popular when I have such a large library of videos already completed. Also, my book is almost out - so I’m hoping that this new influx of viewers will want to buy the book and people who buy the book want to watch the videos and they’ll be a nice positive feedback loop. 🤞 Cheers Kathy
Bohr's stating that electrons in an atom are stable and do not radiate is a critical intellectual leap that shows his genius. Years ago, I read a long quote (which I abbreviate below) from Professor JA Young that nicely describes this kind of insight: … no important contribution was ever first conceived in a manner consistent with what was then known factually -- otherwise someone else could have made the contribution earlier … In each instance, someone had to make a wild leap -- to his credit (since we tend to forget the 'crackpots' who did the same and missed) … This … attitude should be transmitted … This is the poetry of science. Great video.
You are beautifully condensing, ordering, and explaining such a depth and breadth (must be a few hundred books worth?) - the pieces seem the perfect size and your enthusiasm contagious. Thank you so muc,
Kathy always has a different look with every video. I like that. And the content is always excellent. I even eventually got used to the musical introduction which at first was a put off ... Sometimes I even watch one of these several times. Thanks Kathy!
My two favorite topics, science and history. People with our interests also like old movies ( I glimpsed an old movie poster in one of your shots). There is quality in things of all generations. An appreciation of how we got here is most important so we can travel forward. Just discovered you and am watching every single episode. The math derivation of the Bohr model was fantastic.
Hello 👋 Julie. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
Your channel is great. Your statements on Tesla emanate with a particular vibrational resonance. His work and his insights far surpassed many of his time. Others less talented as Thomas Edison, would speak down upon him because most could not “get his vibe or see his vision”. To them his ideas could not be grasped and they said his ideas were “impossible”. Yet, when Einstein was asked about the most talented he referred to Tesla. One Love.
Kathy, delighted by your history od Bohr model. While teaching Bohr model and Rutherford model of atom in Physics, I had never thought of the historical beats. Physics with history is really entertaining. Love the way you have presented Bohr model..
What a fascinating story. Thank you very much Kathy. It is both edifying and captivating at the same time. Edifying because complex ideas are presented with great clarity and captivating because the video brings forward the human element involved. The story of Willemina Fleming and her fellow lady astronomers is just too fascinating for words. Thank you once again. 🙏
Hi Kathy, This is the first video of yours that I came across and immediately subscribed to your channel. Your bringing in history puts things in their context and bring in a kind of Bayesian wisdom to the facts being described
I am sorely tempted to only watch physics explanations from you. You have set a new standard for quality of scientific as well as humanistic explanations. While I sincerely doubt that you are subject to the basic emotions of pride and self-satisfaction, you more than deserve to indulge in these emotions. I lack the words to describe the excellence of your presentations.
Hi Kathy, your love for physics history shines bright, and your explanations are intelligent, well-organized, and crystal-clear :) One little point at 14:30, "came not from the energy of the electron,..." perhaps you meant "frequency of the electron" or "acceleration..."?
I got recommended this video somewhat randomly, and I did not realize that this was an up-and-coming channel until the end; it is of the similar quality to channels with hundreds of thousands if not millions of subscribers! Great content, good presentation, and apparently the ever important TH-cam algorithm is taking notice! Thank you for the interesting look at some of the story behind what would evolve into an integral part of modern-day Chemistry. Some constructive criticism going forward: your presentation can be a bit rough around the edges at some parts, for example the animation at 13:50 half showing then hiding something. The intensity of your lighting could be tuned down just a tad, and I think there were a couple places were the narration had slipped up. Other than that, I think it is great. Your style/vision for the presentation is very clear yet engaging enough with what you are saying to add to the story, and the content I found interesting. As a former Chemistry student, you don't always have the time to go and learn all the history behind the names and theories you learn, which is a shame because the stories can often be almost as interesting as the ideas they produced!
Thank you for the suggestions. This is a one woman operation and I knew nothing about animation or filming or editing before I started (I still don't know very much). I am glad you like my videos aside from the details. Maybe, someday, my videos will become so popular that your comment about my "up and coming" channel will seem funny! Here is hoping.
Indeed. I hope my comments were not taken harshly, but only as information to be used if you were thinking of how to take your productions even further, as it can be difficult to improve without any feedback for what should be focused on. Let it be clear that I do greatly enjoy the content and since my comment have watched the videos regarding Planck.
@@PajamaMan44 I took your comments as useful and complimentary. I really like (and need) editing and filming tips, and appreciate them especially from people who just want to help me do better. Thanks again, Kathy
Fantabulous! The Dane was a hyper genius. Tis delightful to learn about Pickering and his coworkers. He was brave and insightful. I suspect that the women were far more productive than the same number of men would have been. Obviously, they were exceedingly intelligent. We can’t wait to hear more. Terrific job, thank you
Fantastic lecture Kathy! Thank you (I think because I'm sure to spend too much time watching them!) As an E.E. I was hooked first by your piece on Ohm. Getting the human background to evolution of these discoveries is wonderful!
Please tell me you've written a book about all this. It reminds me very much of the 'chemistry' version of history 'the periodic tales: the cultural history of the elements from arsenic to zinc'. I've always loved the history of science because it makes sense of every discovery before it in a way that is grounded in reality. And also grounded in the troubles of them making the next step that we see in retrospect.
Hello 👋 Keith. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
Fascinating and illuminating video. Thanks for taking the time to research and produce these. I recommend doing one on Max Born and one on the Born-Einstein correspondence. They were full of objections from Einstein based on thought experiments and Born’s responses. I’m sure you are aware that Schrödinger, Heisenberg, and Pauli were students of Born.
Hello 👋 Amitava. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
Kathy - I am riveted by your videos! I love that you mix in theory with history and the progression of the topic at hand through the years. Many of these topics are taught in education in a very dry , matter-of-fact way and are forced on you as this is the way it is. It also helps that you are so enthusiastic and excited about the subject that makes these videos entertaining as well as informative. It also helps that you know your SHIT! LoL Thank you! ~KT
Your wonderful stories breathe life into the stuffy explanations of scientists I learned in college. These are on par with Richard Rhodes Pulitzer winning book “The making of the atomic bomb”. Absolutely delightful. I now have something to listen to each day as I travel to work. Much thanks!
I am so thankful for your sober, proportionate, and straightforward presentation of material on Physics, and it's history... Even though "sober' in its fair-mindedness and even handed way of presenting all the players complete with their strengths and weaknesses, You have no lack of passion for Your subject, and present rather difficult math and explanations in a very cogent and compelling, but in an easy to understand way! Kudo's. I so look forward to more ! ! ! ! If only i had had such a great teacher, with an understanding of Physic's when i was young, I might have had a different career.

Kathy, thank you so much for all of this information, I'm a studying electrician in England, you've helped me understand enough about electricity to realise that I'll never understand! I love your videos and your passion for the subject makes it so enjoyable to learn. Thanks again!
I found this fascinating, so much better getting the history of discoveries than just the normal lectures, and your enthusiasm is just a joy
Excellent presentation. I am really enjoying your videos on the history of physics and its related mathematics. I think that I will end up watching them all. Thank you for your good work.
I LOVE this. Also love your other videos on Heisenberg and your general storytelling style. After watching Oppenheimer I find him, Heisenberg, Bohr and all the famous theoretical physicists of that age so interesting. How they were so brilliant, how they disliked each other's theories, how they lived through WW2. 🙂
On a sidenote, I'm personally really interested in theoretical finance (models and such) so now I wonder if there's something similarly interesting in the history of finance and its famous researchers. 😁 But seriously you're such a good storyteller! Just amazing!
Also, your video description is perfect :)
Your videos are amazing! I've been binge watching the content on your channel for a few hours now and your presentation is very good (despite the need of a little audio editing).
Thank you. Am working on the audio quality.
What a fascinating, entertaining, and delightful lecture on the history of the birth of our modern understanding of the atom. Thank you so much for your presentation.
So glad you liked it
I've read books (well, okay ... I listened on my phone to books being read) about the history of discoveries in particle physics and electricity during the 1800s and early 1900s, and I absolutely loved them. Kathy's video here focuses on a portion of what those books covered with added information that makes learning about this subject so wonderful. Thanks, Kathy.
Please can you suggest the title of some of those books.
I love your enthusiasm for science and history. Keep up the great work!
Kathy, thank you for your very nice presentation. Such details cannot be found easy about these giants in science. It happened that in 1958, I bought a book "The Atom a Giant"" written by Karl Bohm and Rolf Dorge" translated from German language to Romanian language. Since than the atomic physics is my second passion after Organic chemistry. I noticed your books from your shelves in the background that looks like my books in one of my pictures. CONGRATULATIONS!
Hi Kathy.
I do not have a formal education in science but I love it and am always in the look for information.
I am writing a blog about the Solvay Conferences and looking for information I suddenly came into you and I am thrilled!
This was really interesting and I want to thank you for doing this.
I'll be following you from now on.
Thanks again. Your enthusiasm is contagious.
I am so happy I've found your programs on TH-cam! I'm very old and, thanks to you, have become engaged in recovering lost math to better follow your talks.
You present so beautifully it is a joy to benefit from your work!
i love how passionate and cheerful are your science history presentations. Thanks for your work.
Tragically underrated channel. I’m bing watching all I can! Thanks for doing this.
I am so thrilled to have found your channel and am treating myself to one of your videos each night. My background is Oxford Chemistry. Research: Free radicals in solution. Mind boggling!!!!! Well ......Anyway I have long known the sequence of arriving at the planetary model - and have read acounts in both popular and academic works. However, your video is far and away the clearest, the most memorable and most entertaining of them all. I love the way your bring the scientists to life in your videos. I have always believed that science from Michelson Morley to the first atomic explosion is the most fascinating and wonderful story in history. If only there was a Shakespeare to turn it into a 'History Cycle'. One legendary genius after another. For a while scientists were that unpolitical, free sharing band of brothers they all believed in. How sad that today scientists often have to hold their tongues or lose their funding. Sorry for rambling on, this was just to say GREAT VIDEO
My last dose of formal physics education was in my Paleolithic period (AKA: a public high school class near Chicago.) I pursued a humanities degree in a small college . . . but I now revere everything I am learning about Prof. Niels Bohr. Kathy is a wonderful science history teacher!
Hi Kathy from New Zealand. Recently subscribed to your channel and been watching your vids, which are very interesting. Back in the early 1980's me and my brother were deeply interested in studying Physics and Mechanical engineering in the US. At that time we were living in one of the Gulf states and had travel restrictions so sadly had to shelve our science education plans. Physics is such an interesting subject and I totally love it and can relate to your videos. Cheers!
I am so glad I discovered your videos! Thanks for the hard work and the love you have put into each one!
Great Kathy. So enthralling. Thanks so much
Hey Kathy! I am an old science teacher and I just discovered your videos the other day and have used a couple in my lessons. I'm a big fan of science history. Great story telling!
So glad you liked it.
Thank you so much for such an amazing video! I just started studying quantum physics and am amazed at the personalities involved, the upsets, the rivalries. What a fascinating time to be a scientist! Brief tidbits and anecdotes included in textbooks about some of the history were not enough for me and I stumbled across your channel to find more.
You deserve so many more subs. I love how thorough your treatment is of Bohr's life and also appreciated learning about how important many women were in the direction of developing and also challenging the Bohr model. The story of Felming is also very inspiring.
Next video I watch will have to be on the great Bohr-Einstein debate.
When you are talking with such enthusiasm it lightens the room. Thanks for all the research you have done and for revealing all of this. I never knew anything about the back story. Fascinating.
So nice of you
I really loved your chat. It enlighted me about the importance of Bohr's model considering I'm not physicst nor chemist. You made it accessible and understandable. Thanks a lot
Soooo much in each episode. I have to break each episode down and investigate the topics being discussed. You are such a great teacher! Thank you so much for creating these videos.
So glad you liked them. (This one is a favorite of mine)
Hi Kathy! Im one in the wave of new subs. Only found your videos 2 - 3 weeks ago. Yesterday I went to your channel to find more vids only to discover I had binged your whole library - 2. Several I had watched more than once. Not as background either. Full attention. Maybe its a gooid thing the algorithm waited awhile to show you off. Let you build your library and tune your skills, before the whole world came to your door. Thank You so much. Your love of the material is just infectious. ... Stay well, now that your recovering. :)
I really do think that I had the best of all possible timing (aside from getting breakthrough COVID 😩). I have been told by several people to produce shorter videos more frequently and on a regular schedule and… That’s not what I want to do.
These videos take time and I want to have enough space to really explore and deal with depth so I’m very happy that I’ve gotten more popular when I have such a large library of videos already completed.
Also, my book is almost out - so I’m hoping that this new influx of viewers will want to buy the book and people who buy the book want to watch the videos and they’ll be a nice positive feedback loop. 🤞
Cheers
Kathy
@@Kathy_Loves_Physics Make the videos the size you think they deserve. We will take the time to watch.
This was excellent!! I really love your videos so well documented.
NicleT thanks.
Another fascinating lecture of legends of physics having trouble, doubt, misunderstandings and celebrations of
discovery! Keep them coming! Thx.
I love this. My Father had him as his physics lecturer just before WW2 started. What a lucky kid.
Really. Wow .❤. I hope if my luck would be as lucky as your father.
09:00 That aside about Margrethe was so cute. Thanks for sharing!
Bohr's stating that electrons in an atom are stable and do not radiate is a critical intellectual leap that shows his genius. Years ago, I read a long quote (which I abbreviate below) from Professor JA Young that nicely describes this kind of insight:
… no important contribution was ever first conceived in a manner consistent with what was then known factually -- otherwise someone else could have made the contribution earlier … In each instance, someone had to make a wild leap -- to his credit (since we tend to forget the 'crackpots' who did the same and missed) … This … attitude should be transmitted … This is the poetry of science.
Great video.
You are beautifully condensing, ordering, and explaining such a depth and breadth (must be a few hundred books worth?) - the pieces seem the perfect size and your enthusiasm contagious.
Thank you so muc,
Thank you so much!
Kathy always has a different look with every video. I like that. And the content is always excellent. I even eventually got used to the musical introduction which at first was a put off ... Sometimes I even watch one of these several times. Thanks Kathy!
My two favorite topics, science and history. People with our interests also like old movies
( I glimpsed an old movie poster in one of your shots).
There is quality in things of all generations.
An appreciation of how we got here is most important so we can travel forward.
Just discovered you and am watching every single episode.
The math derivation of the Bohr
model was fantastic.
I just found your channel and I'm in love! This is wonderful work, thank you!
Hello 👋 Julie. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
A fine book that tells the story of Wilhelmina Fleming and Pickering's "computers" is "The Glass Universe" by Dava Sobel.
I’ve read it and it’s very good!
"Pickering was amazed to find Wilhelmina was a natural astronomer." don't know why but I started laughing
I did too. I think it was in admiration of the man's human generosity.
Your channel is great. Your statements on Tesla emanate with a particular vibrational resonance.
His work and his insights far surpassed many of his time. Others less talented as Thomas Edison, would speak down upon him because most could not “get his vibe or see his vision”. To them his ideas
could not be grasped and they said his ideas were
“impossible”. Yet, when Einstein was asked about the most talented he referred to Tesla. One Love.
This channel is a gift to humanity.
Oh my goodness thank you
Kathy, delighted by your history od Bohr model. While teaching Bohr model and Rutherford model of atom in Physics, I had never thought of the historical beats. Physics with history is really entertaining. Love the way you have presented Bohr model..
Thanks, I like the expression historical beats, it’s excellent.
What a fascinating story. Thank you very much Kathy. It is both edifying and captivating at the same time. Edifying because complex ideas are presented with great clarity and captivating because the video brings forward the human element involved. The story of Willemina Fleming and her fellow lady astronomers is just too fascinating for words. Thank you once again. 🙏
Hi Kathy,
This is the first video of yours that I came across and immediately subscribed to your channel. Your bringing in history puts things in their context and bring in a kind of Bayesian wisdom to the facts being described
I love everything about you and your channel. I hate to see them end!!
I am sorely tempted to only watch physics explanations from you. You have set a new standard for quality of scientific as well as humanistic explanations. While I sincerely doubt that you are subject to the basic emotions of pride and self-satisfaction, you more than deserve to indulge in these emotions. I lack the words to describe the excellence of your presentations.
Love the way you talk about phisisists, it makes for me, a very dry subject into a delightful one. Thank you
Hi Kathy, your love for physics history shines bright, and your explanations are intelligent, well-organized, and crystal-clear :) One little point at 14:30, "came not from the energy of the electron,..." perhaps you meant "frequency of the electron" or "acceleration..."?
Your videos are AMAZING!! I love the combine history and the sciences. You should have a millionaire subscribers!
I got recommended this video somewhat randomly, and I did not realize that this was an up-and-coming channel until the end; it is of the similar quality to channels with hundreds of thousands if not millions of subscribers! Great content, good presentation, and apparently the ever important TH-cam algorithm is taking notice! Thank you for the interesting look at some of the story behind what would evolve into an integral part of modern-day Chemistry.
Some constructive criticism going forward: your presentation can be a bit rough around the edges at some parts, for example the animation at 13:50 half showing then hiding something. The intensity of your lighting could be tuned down just a tad, and I think there were a couple places were the narration had slipped up. Other than that, I think it is great. Your style/vision for the presentation is very clear yet engaging enough with what you are saying to add to the story, and the content I found interesting. As a former Chemistry student, you don't always have the time to go and learn all the history behind the names and theories you learn, which is a shame because the stories can often be almost as interesting as the ideas they produced!
Thank you for the suggestions. This is a one woman operation and I knew nothing about animation or filming or editing before I started (I still don't know very much). I am glad you like my videos aside from the details. Maybe, someday, my videos will become so popular that your comment about my "up and coming" channel will seem funny! Here is hoping.
As a one woman show , it's as good as it gets. Thank you kathy!
Indeed. I hope my comments were not taken harshly, but only as information to be used if you were thinking of how to take your productions even further, as it can be difficult to improve without any feedback for what should be focused on. Let it be clear that I do greatly enjoy the content and since my comment have watched the videos regarding Planck.
@@PajamaMan44 I took your comments as useful and complimentary. I really like (and need) editing and filming tips, and appreciate them especially from people who just want to help me do better. Thanks again, Kathy
Such colorful and informative narration. Thanks!
So glad you liked it
Fantabulous! The Dane was a hyper genius. Tis delightful to learn about Pickering and his coworkers. He was brave and insightful. I suspect that the women were far more productive than the same number of men would have been. Obviously, they were exceedingly intelligent. We can’t wait to hear more. Terrific job, thank you
I can't tell you how much I enjoyed this recounting of the history of Bohr's model. Just Fantastic. I'm subscribing right now.
Thanks
Thank you, Kathy! What a wonderful job you do! Love the stories you tell and your cheerful, clear and easy to comprehend art of doing it!
Thumbs up! 👍
Thanks 😊
What an amazing channel!
A really excellent perspective of the history of science with equally robust but understandable scientific explanations. Science in contact. Great!
Fantastic lecture Kathy! Thank you (I think because I'm sure to spend too much time watching them!) As an E.E. I was hooked first by your piece on Ohm. Getting the human background to evolution of these discoveries is wonderful!
Please tell me you've written a book about all this.
It reminds me very much of the 'chemistry' version of history 'the periodic tales: the cultural history of the elements from arsenic to zinc'.
I've always loved the history of science because it makes sense of every discovery before it in a way that is grounded in reality. And also grounded in the troubles of them making the next step that we see in retrospect.
Thanks Kathy. Excellent video. Have posted a link to your video on my FB page to explain the complexity and inaccuracies of early research in physics.
History and science, the human discovery's of how the univers revels itself. Your enthisum makes learning a joy.
Hello 👋 Keith. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
Thank you Kathy. I always enjoyed the story of Bohr's model and Rutherford.
aDDING SCIENTIFIC breakthoughs with historical context made the subject so very real , graet work Kathy
Very well done. I enjoyed how you presented this, skillfully weaving the narrative between the personal and the scientific.
Kathy should be awarded the Nobel Prize for Brilliant Lecture on physics for this video.
Thank you so much!!
Fascinating and illuminating video. Thanks for taking the time to research and produce these.
I recommend doing one on Max Born and one on the Born-Einstein correspondence. They were full of objections from Einstein based on thought experiments and Born’s responses. I’m sure you are aware that Schrödinger, Heisenberg, and Pauli were students of Born.
Hello 👋 Amitava. How are you doing ? Hope you are fine. I'm Mark Clifford and am from Denver Colorado, where are you from ? You seem like a real country girl
Kathy - I am riveted by your videos! I love that you mix in theory with history and the progression of the topic at hand through the years. Many of these topics are taught in education in a very dry , matter-of-fact way and are forced on you as this is the way it is. It also helps that you are so enthusiastic and excited about the subject that makes these videos entertaining as well as informative. It also helps that you know your SHIT! LoL Thank you! ~KT
Your wonderful stories breathe life into the stuffy explanations of scientists I learned in college. These are on par with Richard Rhodes Pulitzer winning book “The making of the atomic bomb”. Absolutely delightful. I now have something to listen to each day as I travel to work. Much thanks!
I am absolutely intrigued by this channel, its content and especially its presentation (including singing!).
That might be the only time I have ever been complimented on my singing 🤣 thank you!!
Love that song of physics.... definitely singing on my birthday 😂
Got to keep up the traditions!
I love your videos. Just found your channel ... It's absolutely wonderful the fact that you tell physics like a story time line...🙏🙏🙏
fariborz khademian aww thanks
I really enjoy all the human angle you present which really enlightens the physics beyond the cold facts.
I am so thankful for your sober, proportionate, and straightforward presentation of material on Physics, and it's history... Even though "sober' in its fair-mindedness and even handed way of presenting all the players complete with their strengths and weaknesses, You have no lack of passion for Your subject, and present rather difficult math and explanations in a very cogent and compelling, but in an easy to understand way! Kudo's. I so look forward to more ! ! ! ! If only i had had such a great teacher, with an understanding of Physic's when i was young, I might have had a different career.
I really enjoy your channel Kathy - thanks for the great videos! Also, glad to see Kazantzakis on your book shelf :-)
I just discovered this channel. It is soooo good! A new favorite.
Your videos are fantastic. I hope to share them with my students.
