Hi yes, i understand that. But I am unable to work the math out, specifically the second +$\frac{1}{2}$

Would anyone explain how the calculation in the picture was carried out? (the second equal sign) I don't seem to be able to get the indices right.

Thank you!

Hi that is my problem. I wasn't able to incorporate (2.69). Is there an idea?

The attached pic is from Schwartz. Can someone explain the second equality sign in (2.72)?

Would someone explain the last step in eq.(2.34) in Heald and Marion? Much thanks ahead.

Yeah exactly. I am just wondering whether anyone knows any such places.

Mainly students who are interested in learning physics. (Free classes, you can come. No need to pay)

You don't have to be so sarcastic. I meant a school designated for the subject for physics only.

Ok. What I meant is a school (with teachers, not online) designated specific for physics, and not for intro courses, but for high level physics. Like think of a physics professor just quit his job at Harvard and open an independent institution not affiliated with anybody or any other schools.

Is there an institution or maybe just a small agency out there purely for physics education? I am not talking about high schools or universities. I am referring to classes outside of school. Thanks ahead for any sort of insight!

Very helpful! Yeah, I did troll through every single one. And the likelihood of getting into MIT or Harvard would be so low for physics undergrads from liberal arts colleges though. You are nothing compared to people from top undergrad institutions. That is quite frustrating!

I understand. But if you go through the professors at big/top institutions, rarely will you find one that started off at a Liberal Arts College.

How rare is it that some physics student from a random liberal arts college go on to the likes of Harvard and Princeton for grad school and postdoc and now is a renowned physicist in the field? Do you know anyone like that?

Ok! Thanks, appreciate it!
