They should just project this video during lesson on atom spectrum for kids at O and A levels. It saves weeks of head scratching and more kids will take an interest in atomic physics. Excellent
It's not easy to produce high quality content for such a small audience. But I am confident in saying that this channel will be among the top resources for newcomers to the quantum world for decades to come. Keep up the good work guys!
It will take me more than one viewing to digest this, but that's the kind of technical depth that I love. This is university-level material, without having to live in a dorm and take out a student loan. Thank you for posting it.
Another great video. If you want to continue on this theme, it is a great opportunity to discuss how high precision measurements allow you to determine other interesting things, such as the mass of the nucleus, or its charge radius. This allows you to discuss Pickering-Fowler lines, the discovery of deuterium, and even the standard model, when discussing the proton charge radius (by comparing hydrogen results to muonic hydrogen results). When discussing fine structure, it might be useful to also discuss the Lamb shift (not necessarily the derivation, but the experiment) as it is an incredibly clever experiment using lots of atomic physics to make it work. An interesting story about Pickering-Fowler lines is that Einstein is said to have noted that Bohr’s correct prediction of singly ionized Helium as the source was confirmed by the effective mass and how it modified the spectral lines. Einstein said this is proof Bohr has the right theory. But, of course we know that was in error.
8:41 You show all the constants to 4 significant figures , but derive the Rydberg constant to 6 significant figures. Not good practice. … but great vid nonetheless. 😊
You are absolutely correct. In our calculations we actually used 10 significant figures, so the underlying numbers should make sense. However, we should definitely have clarified this point in the video or stuck to better practice. Thanks for the feedback!
Do you guys think you'll do a video on the fine and hyperfine structure of the hydrogen atom? I am yet to find a nice mathemtical treatment of the hyperfine structure and would love to hear your guys take!
Can't wait until they cover "electron degeneracy pressure" someday. I read, that pressurized matallic hydrogen become superconducting. Maybe this superconductivity is the reason for jupiters huge magnetic field, if that hydrogen is in the core. And this field influences jupiters neighborhood, so everything is connected to everything, in the fabric of the universe 👽
Electron degeneracy pressure is a very interesting topic and it would be great to cover it in the future, thanks for the suggestion! And yes, it is believed that hydrogen under extreme pressure (higher than that at the center of the Earth) should become superconducting with a relatively high critical temperature, perhaps higher than room temperature. However, hydrogen inside Jupiter is probably at even higher temperatures so it is unclear whether it would be superconducting; but just metallic hydrogen is thought to play a key role in generating the magnetic field around Jupiter :)

Glad you like it!!

Thanks for the comment and insights into these topics! We'll look into these for possible future videos :)
Had been so eagerly waiting for this one.....I really wish that someday I could meet with your team in person and have a long conversation. ❤
Glad you enjoy our videos, and we hope to explore avenues to connect better with the community :)
I’m a simple person, I see a professor m does science video, I hit like. 🙌
Thanks for your support! :)

We are hoping to get to both in the future, yes! :)
