I tried writing a free textbook as an undergraduate. It's on quantum mechanics derived from first principles -- https://quantum.chaidhat.com -- hope you like it!

If you want to learn more about quantum mechanics starting from 1+1=2 please check out https://quantum.chaidhat.com !

do you work at Uber by any chance?

Thank you!

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.

I prefer to do startups!

Thank you! Glad to hear you like it!

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

Maybe they should stop pushing these bankers to do 48 hour shifts…

These are not bankers, but the culture is still bonkers
