PART 1: https://www.youtube.com/watch?v=e5_V78SWGF0
Today we’ll be exploring the evolution of the atom, starting from J.J. Thomson’s Plum Pudding model, on to Rutherford’s Planetary model, and then on to the Bohr model, which is one of the central focuses of this lecture. After going over the strengths and weaknesses of each, we’ll see how de Broglie’s crazy ideas about the duality of matter manifest themselves in the Bohr model, which we’ll use to (partially) derive the Rydberg equation. Finally, after calculating the Balmer series in order to show off how successful Bohr was, I’ll ruin the moment by explaining why Bohr’s model wasn’t complete after all. Some very important questions will be raised, and the answers… well, the answers will blow your mind in the next episode.
This video is less dense than the last one, and certainly less heavy on the maths than the next one. For those of you who paid attention in high school chemistry, at least half of the content here will be review. If this video seemed a little bit too basic, don’t worry- the next video will be the most difficult one in the series. The goal here was to provide a setup for what’s to come- you’ll probably need to revisit this video a few times, since there are things that I mention here that will be explored in much greater depth later on. Now that all the pieces are in place, though, we can finally get to the bread and butter of quantum mechanics in the next video. Stay tuned.

If you pledge at least one dollar, you will be credited on most videos (excluding shoutouts/announcements and rare special features.)
Every dollar will count as a raffle ticket to monthly giveaways of popular science books for laypersons. 1 dollar = 1 raffle ticket, 10 dollars = 10 raffle tickets, etc. For every $100.00 US dollars pledged in total (over both Patreons), an extra book will be raffled each month. At the time of this video’s upload, the total amount pledged is over $200.00, so 2 books are raffled away each month. When it reaches $300.00, three books will be raffled away each month. And so on.
