Thanks. I wish I had a professor like this. Thank you MIT for the great service for those who are underprivileged.

i go to ucla, but i wish i went to MIT.

confusing question at 1:10.

It has 2 subshells, d and f, d has 5 orbitals, f has 7 orbitals...=12 orbitals total

ml says there are 10 orbitals..= -2,-1,0,1,2 x 2 (l=3, 2) = 10 orbitals total

is she adding the possible orbitals and substracting ml?

Or should the question just be how many subshells?

That is very odd. I have two books that actually say the opposite. From his biographical snippet on page 312 of "Modern Physics" by Taylor, Zafiratos, and Dubson:

"He generously credited others with ideas that he originated and detailed in letters to colleagues, but did not publish."

I looked on pages about Goudsmit, Pauli, and electron spin; and there is no info about them meeting before the paper was published. Is she confusing Goudsmit with Ralph Kronig?

@Briggie

Whenever she speaks about history, I feel like she is just repeating urban legends and gossip.

Really great teacher. Its a really hard topic to study right out of the book

Clear, concise, smart and cuteness = WIN!! . Thanks professor. sorry didn't mean to creep but i can't help my hormones.

Too bad I'm not smart enough to learn all these things at such a speed. .. :(

[bomberfun1]

nice woman, other professors should learn from her how to behave yourself with students.

[greyteo]

interesting story about Pauli. wow.

[arsenelupin123]

@greyteo

From what I've read she's grossly exaggerating what happened.

[arsenelupin123]

Here is the true story that she deliberately amplified to be interesting.

Pauli invented the new qu. number one year before Goudsmit and Uhlenbenck did their measurements. Then Kronig, not Uhlenbeck or Goudsmit, went to see Pauli to discuss the spinning elec. interpretation, and Pauli criticized it heavily (with sound arguments) so that Kronig decided not to publish. When Uhlenbeck and Goudsmit published, Kronig tore his hair out.

She got it SO WRONG. Was it so hard to google this? Fuck.
