    I’m so glad you did the math with historical commentary. Great job! My teacher in Modern Physics did all the same math but without the historical motivation. Showing how the sausage was actually made helps young scientists understand how to approach the scientific process better. Every undergrad physics/engineering major should watch your series. Thanks.

    One of the biggest hurdles that made my mind blocks physics in the colledge was why on earth did these famous ones think about what they were working on. If I knew the historical background, many seemingly non logical aspects of physics would have come clear and smooth. I do not claim I understood everything thing you mentioned, but I really wish I had a teacher like you. Thank you for the video and the explanation included therein.

    • @dbmail545
      @dbmail545 2 года назад +6

      Read "Mr Feynman, You Must be Joking". Feynman made a prediction that was more precise than the measurements. When he heard that a more precise measurement had been made, he sweated bullets until the paper was published that showed that the new measurement was closer to his prediction than the earlier measurement, rather than farther from it. Theory always has to be shown experimentally to gain traction.

    Wow, Kathy. That was a fantastic video. It brought back so many memories of my undergrad physics class in spectroscopy. That's where I first encountered the Bohr theory of the atom formally. I'd read about it in high school, but didn't understand the math. My spec instructor was a very practical guy who worked in one of the physics labs for Dow Chemical in Midland, MI. I learned so much from him.

    It is always welcome, having a complex topic able to be made understandable by someone with the right knowledge - thank you.
    It has always puzzled why the electron remains where it is and fails to lose energy and does not fall into the nucleus, because of the proton-electron attraction. The satellites we send to space are powered to remain in orbit; when they are old and lose the energy and the means to correct/re-establish a proper orbit, they fall to Earth and the atmosphere has the final say. Electrons do not have on-board systems to correct/maintain an orbit yet there they are.

It was a tough school and only got harder from there. 4 of the most grueling years of mental work in my life and worth every second of it. This quantum jump comes up over and over again especially in electrical engineering. It's one piece of evidence for a possible additional dimension we can't sense.

    I have intended to do something like this for a while but looks like Kathy is more energetic then me. This issue has bothered me for a while since I read through Bohr's original paper. All of the intro textbooks get this wrong, claiming that Bohr quantized the angular momentum which lead to his result. I think it is enlightening to read the paper and realize that Bohr basically pulled the "average angular frequency" out of thin air and then concluded that the angular momentum is quantized.

    Note that with quantum mechanics, the values are all discrete so they all belong to the set of Rational numbers (can be equated to the discrete sequence 0, 1, 2, 3, ...) as far as going from one to the next one. This means that the scenarios that create these results are also discrete (completely separate from their nearest neighbors). This result implies that if there is a multiverse interpretation of these rules (Everett "Many Worlds" interpretation), then each universe of this multiverse is completely separate from all others, too. They are thus not points on a line with no visible boundaries between such points, as in the infinitely larger set of Real numbers. This not only changes the results, but the concepts on which these results are based and is one of the basic differences between quantum physics and all forms of non-quantum physics (Classical, all forms of Relativity, etc.).

The acceleration that was expected to produce classical radiation is centripetal -- like a cyclotron. Rotation implies spin which wasn't a consideration in Bohr's model.

    I’m sorry to be a nit-picker on terminology, but I feel that in this model the electron “revolves” around the nucleus, it does not “rotate” or “spin.” I think this distinction is important if you are writing a book on quantum physics, as spin is another concept :)

    Please enlighten me. One can consider 'electron motion in an atom' from two perspectives, classical and quantum. The quantum picture relies on a statistical formula, the Schrödinger equation. It comes up with maximum 'entropy' solutions for the statistical shapes of the orbitals. The classical approach needs to take the quantum idea of somehow canceling the radiation from the electrons in their orbits. Then it is left with the task of solving ordinary differential equations including the effects of electron spin: a hopeless task, considering that the solutions are most likely deterministically chaotic. Is there any mathematical way of checking whether those chaotic solutions might have statistical properties that could be compared with the Schrödinger maximum 'entropy' solutions? Please enlighten me.

    What really amazes me is the elaborated model, sometimes called "the old quantum theory", that Bohr and Sommerfeld developed, in which they started introducing elliptical orbits with the same principal quantum number and different angular momenta. What specifically fascinates me about it is that they would have been able to take it much further than they did had all of their angular momenta not been off by one unit of hbar! It was a mistake that was easy to make because of the energy degeneracy of different angular momentum states for hydrogen-like atoms, and maybe the idea of an electron with ZERO orbital angular momentum and an orbit that bobs in and out, right through the nucleus, was just too absurd for Bohr and Sommerfeld to contemplate. Once wave theory arrived it wasn't quite so absurd.
    It was maybe the most significant off-by-one error in physics, one that contributed to further progress, since it led physicists to abandon "the old quantum theory" with quantized orbits earlier than they might have otherwise.

    Two physicists meet in the hallway.
    Quantum physicist: What’s up with your area?
    Classical physicist: Negative Del dot g, like always. What’s new with you?
    Quantum physicist: E over h, as usual.

    What is the frequency of rotation in such a small atom? Can you give an example? Great video.

      Jr cary thomas glad you liked it. Frequency of rotation meaning how often the electron circled the nucleus

      Kathy Loves Physics & History Are you talking about megahertz, kilohertz, etc can you give an estimate for hydrogen?

      @@225rip I think you can check out the hydrogen spectral series (en.wikipedia.org/wiki/Hydrogen_spectral_series), there they give it in nm but since it's light you can turn that into corresponding frequencies. I think they end up in the petaHertz range (www.chemguide.co.uk/atoms/properties/hspectrum.html)

      chuvzzz Thank you for getting back to me with an answer and a source to look into. I am thankful for people like you that can come along and fill in the gaps for me. Thanks again!

    Great video. As an update, some inventors under patent have demonstrated electron states of 1/2 and 1/3 electron orbital states. Some physicists claim this is not possible even though it works. We have to break out of the faulty disinformation Einsteinian physic theories once and for all!!

    "An infinitely big Nucleus", that would be a ONE-INFINITY Singularity Universe of Logarithmic Time, in which deterministic pure-math relative-timing ratio-rate quantization is the fundamental self-defining Holographic Principle Reciproction-recirculation manifestation of all physical phenomena, such as been illuminated, made real-time Actuality.., so well in this video.

    So a zero is a naught but nothing is a different naught? BTW I am more familiar with "ought" for zero as in the rifle cartridge 30-06 which is usually pronounced "thirty ought six"

    Love your channel. However, Potential energy in a closed system always equals Kinetic energy in that same system when converted. Law of conservation of energy. What I see above is someone in history not accepting the nucleolus to also be revolving around the electron with the same energy as the electron is sweeping around the nucleolus.

    It seems the idea it is in orbit is in the calculation, and yet is this the quantum interpretation of the position of an electron?
