In this day and age with how widespread AI-voiced RUclips channels have become, I can really appreciate an actual human speaking out the script (or, at least I think it is lol).
I’m an IB DP physics teacher. These videos are all excellent alternative means for students to learn about the nuclear physics portion of the course. Keep putting out this great content please! Your videos are forming a core part of my course for my students!
"Electromagnetic Fields and Waves" by Lorrain & Corson (2nd Edition) contains a problem in chapter 2 "Electrostatic Fields in a Vacuum" (2-19) on J.J. Thomson's "Plum Pudding" model of the atom. It asks to (A) find the force on an electron; (B) describe its motion; (C) the frequency for a 1 Angstrom-sized atom; and (D) compare this frequency to that of visible light. A rather thought-provoking question in an Undergraduate E&M textbook!
Although it make good sense for us who understand the solar system’s orbital model we have not yet definitively verified or proven that the same also applies to model of atom other than our declaration and legislation that is so. The alternative thinking is that electrons attach to the atom either insulated (net zero charged) or mutually zero charge and only induce and carries charge at and after separation.
@philoso The Bohr-model of the atom included trajectories of the electrons around the nucleus, comparable to a solar system. But the Bohr model is not up to date and nowadays used mainly for illustration purpose or a very basic approach. Today, we know from quantum mechanics, that there is only a probability-density, which is hard to imagine but good to calculate. And all calculations are in perfect agreement with measurements. That is the verification. A proof is only possible in mathematics.
I know, right? Heard about this experiment a few times now, on a Disney TV show in the early 60s, High School Chemistry and Physics classes and at University. Really elegant. If you think about it for a second or two; you have a positively charged particle moving, at fairly high speed, being emitted from an unstable nucleolus and moving through a metal foil and being detected. The basis for many a design of atom smashers. Just boggle. Y' see what might happen if you think things over? Hint.

Yep, it really is me! It doesn't take too much effort to do a voice over so I don't mind it at all 😁
These men were absolute giants in their field. The world is a much better place because of their contributions.

This really means a lot to me. Thank you so much. 🙏
Lets get this channel where it deserves to be!
definitely

Excellent presentation of the topic with good use of helpful graphics and minimal click bait distraction 👏 subscribed!
please make more videos
Fantastic, tight and informative video!
Another great video. Thank you.
Every high school student ought to watch this vedeo. The roads physics came up to todays level. Thank you sir!
Ernest Rutherford, just another Kiwi at the cutting edge!
Now that's a bow tie!

@@amuller3101I don’t disagree or agree with you of his model. Shall we say that we sometimes mistakenly took correlation as proof?
Very nice video
Well done
