If YouTube was a library MIT open courseware channel must be it's most important books shelf.

I really appreciate these lectures, as well as other OCW series. Ive always wanted to learn GR but never had the chance during ugrad. I’ve been working through carrol’s space time and geometry but found some sections difficult to tackle on my own. It’s incredibly useful to have a recorded lecture to watch as I work through the material! Thanks OCW!

[prashantpanta]

MIT is really great to post this. I have been searching the materials for GR from quite a while that this course comes as a recommendation in my YouTube. But I wasn't able to find one. Now, I get this one. Thank you a lot!!!

[mattagamer]

It is quit mind blowing that we can acces all this information from such a high ranked university, thank you

[TheNevarranSeeker]

Thank you, MIT! I've been taking GR this semester and wasn't getting enough out of the lectures and the textbook to fully understand the material. Having this course available has been an immense help. I'm so grateful for your whole physics OCW library!

[getaphd]

MIT you made my day! Just yesterday I was thinking how good it would have been if MIT had a course on the subject. Thanks! <3

[rifatzehra]

All flowed over my head but I am glad that I watched this anyway .
Thanks MIT 😇

[igorschmidlapp]

Any good relativity textbook is massive enough to have its own gravitational field.... ;-P

I think we need to stop and pause sometimes to realise how lucky we are that this is free and available at a click!!

[peterjesus]

Thanks for giving us an opportunity for the preview of your lectures for those of us who can't afford to get admission at your campus, txs

The manifold discussion was enjoyable to think about, as well as the rest of it.

Beautiful lecture. understood nearly everything. Now gonna test my understanding by doing PSets. Thanks MIT OCW. Thanks Prof.

[personanongrata]

It has been over forty years since I studied General Relativity (MTW and Dirac's thin book). This lecture is a great review for me.

thank you for this MIT, My dream school...

[renrenhamster]

Thanks MIT! I finished 7 MIT physics courses (8.01-8.06 and 8.286) and this is my 8th! Been enjoying it!

For mathematicians, Wald is indeed fine; another suggestion would be Callahan, Geometry of Spacetime. Needham's Visual Differential Geometry with Forms will soon change the way the subject is taught (as his Complex Analysis book did) once enough time passes and enough generations are raised in its greatness - it may be the best textbook in mathematics written in the 21st century so far (and I've read a few), but its focus primarily on diff geo and secondarily on GR may sink it as a singular course text for a grad physics class.

i can't believe this much information for free, i didn't know
