Lmk what you guys think!

Just skimmed it. But I think all math / physics concepts should be taught like this. Thank you for doing this.

Ok, after a few steps, it feels a bit like the meme of how to draw an owl :) (eg some steps are left to be desired, especially after matrix)

Thank you! Haha yes, I think some stuff are out of order (they were once ordered). I will have to revisit and reorder them again

It sounds like an amazing way to learn hard concepts by following a progressive and clear track of knowledge, starting from first principles. Also, the presentation is clean and easy to read, nice job!

Thank you! Glad to hear you like it!

"None of this is written by AI — I am writing this by hand because I find explaining concepts makes me understand them better too."

It'd be interesting if your work was taken up quickly by child prodigies. Maybe have a guest book?

Is there anything you'd still like to put up, but wanted to crowdfund in order to get you motivated and accept ideas?

Do you plan to teach professionally? Maybe you could accept tips?

I prefer to do startups!

"Note that ψ (psi) is pronounced sye and ϕ (phi) is pronounced fye."

This is the American pronunciation I take it? During my undergrad physics and mathematics modules I was instructed by a handful of Europeans (including a charming old Russian for theoretical) who stressed the importance of preserving the pronunciation I'd learnt in classics at school - "(p)See" and "(p)Fee" respectively.

Love the site.

Thank you very much. I never knew of those pronunciations, I will read up on them! I had a Russian physics professor once and he was very suave: he wore aviators during our final exams.

Mine was like an ancient remnant from the soviet union, dry as anything but wickedly funny, used to yell at us if we pronounced the Cyrillics wrong, or more usually if we did not use capitals for units named after people; I can still hear his rebuke "why do we capitalize Newtons? BECAUSE HE WAS A GREAT MAN".

Really punished our (my) youthful laziness.

Awesome way to share what you learned and compound your own learning. Thanks for building this and sharing quantum mechanics!

Thank you!
