Bohr Model: A Delightful History [CC]

[@thomassimmer5186]

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!

[@kimrnhof107]

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.

[@Kathy_Loves_Physics]

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.

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?

"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!

[@bathhatingcat8626]

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.

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.

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!

[@NONFamers]

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!

[@Kathy_Loves_Physics]

I love that story!

[@TheRev0]

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."

[@hank1519]

Kathy, this is one of KZbin's best history of science lectures! Brilliant and compelling!

[@craigfitzsimmons676]

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.

[@robertduncanson1580]

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.

And also grounded in the troubles of them making the next step that we see in retrospect.

[@ziggle314]

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.

[@Borzoi86]

[@eswing2153]

Tragically underrated channel. I’m bing watching all I can! Thanks for doing this.

[@chuvzzz]

Awesome. Bohr sidestepped the biggest objection to the orbiting model, the decay due to radiation-from-acceleration issue, by suggesting that somehow, it does not happen in some minimal state, in the ground state. The radiation pattern in stars, a key observation he was still trying to explain, was still due to the influence of an accelerating electron, but whose stable motion was now constrained by these discrete jumps. So why is the ground state stable? Somehow, because the uncertainty principle implies you can't ask where the electron is at that scale... hmmm... I'm not entirely sure I would say that this "resolved" the objection, but rather that we decided the original objection didn't make sense once we accepted the principles of QM.

[@Kathy_Loves_Physics]

That is what I was trying to say. “We decided the original objection didn’t make sense ...”. That is so well put. Thank you.

[@EricPotratzM]

FYI, atoms do spontaneously emit radiation because of a small probability of excitation and collapse. As far as any EM disturbance at the ground state it may be impossible to detect this EM disturbance separate from the background noise level. Also, at theoretical 0 Kelvin it has been proposed that the "vaculeon charge" does not allow any release of radiation. This is probably a type of near-field (reactive energy) effect which is at the frontier of electromagnetics right now. Also, the ground state does not emit such high energy photons because the electron has approached the nucleus as much as it can, like the ocean water on Earth. (That's similar to how Schrodinger's wave equation applies it) The electron doesn't start behaving like a little orbiting planet until it's around the n-100 energy state like in a Rydberg atom. In the ground state, the electron may also be undergoing self-quantum tunneling (interfolding) phenomenon. Allegedly, the nucleus maintains vast cavernous space that the electron can freely travel through.

[@ronniet71]

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”.

Kathy, I loved this story. Thank you very much. You talk about the electron spinning around the nucleus. This may lead to some confusion since the electron has a property called "spin" which is different from the electron "orbiting" around the nucleus. I put these terms in quotes, because they are not exactly what we normally (classically) think of when we hear them. Perhaps you can clarify that in a comment here.

[@Kathy_Loves_Physics]

Tim Johnson I guess the word spinning was a bad term because I meant orbiting and of course, the whole idea of electron spin was more than 10 years in the future when Bohr wrote his paper.

[@philiphorner31]

And electrons don't exactly orbit. They exist in probability spheres with varying density.

Love the way you talk about phisisists, it makes for me, a very dry subject into a delightful one. Thank you

[@kturek625]

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

Thank you Kathy. I always enjoyed the story of Bohr's model and Rutherford.

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..."?

[@brianstrom3103]

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.

[@ou812grn]

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.

[@Kathy_Loves_Physics]

So glad you liked them. (This one is a favorite of mine)

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!

Nils could change semantics just standing still: An awe-ful Bohr. What an amazing spirit - I like the series of ‘he just believed!’.....great channel - glad I discovered it two days back. Do you know the story of ‘Die Emptfuhrung aus Covenhagen’? by a mosquito! and his nearly dying of cold and oxygen depletion just above the wheels? Expect you do - but if not enough clues....

I sometimes walk by his burial-site here in Copenhagen. I almost always stop and salute him. What a human being he was.

Just a prince.

Beautiful narration of one of the brilliant phycist (and his scientific achievements) ever to have existed on this planet. The story of Pickering was interesting to know. I believe the man shown as Runge is none other than the famous Runge-Kutta method in Numerical analysis. Very glad to know about all these genius men of the past century.

Your videos are AMAZING!! I love the combine history and the sciences. You should have a millionaire subscribers!

[@robertvaughn3554]

Inspired work, I am 72 and have a Ph.D. in physics. Your videos bring back fond memories of reading Gamov's book 30 years that Shook Physics.

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 KZbin 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!

[@Kathy_Loves_Physics]

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.

[@rohanthakur4833]

As a one woman show , it's as good as it gets. Thank you kathy!

[@PajamaMan44]

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.

[@Kathy_Loves_Physics]

@@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

[@ChannelSRL1]

Such colorful and informative narration. Thanks!

[@Kathy_Loves_Physics]

So glad you liked it

[@marcochimio]

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.

[@Kathy_Loves_Physics]

Thanks

I love everything about you and your channel. I hate to see them end!!
