1. View the complete course at: https://ocw.mit.edu/8-962S20. Best wishes on your studies!

2. Any school guy here

3. My Favourite is Physics Specially Quantum Physics. MIT can u tell me can i come MIT UNIVERSITY After clear my 12th class?

4. There is a huge difference in MIT UNIVERSITY Education and MIT OPEN COURSE but MIT OPEN COURSE is better than other College and UNIVERSITY so think that what is inside in MIT i am coming MIT in 2024 It Is my 10th class now but i have seen all lecture from MIT open course Thank you MIT
   Love from INDIA 😊

5. Mit please we need the qft 3 course and the manh body problems ,confesante mattter and highly corrrelate systems please please ,maybe quantum theory and that It

6. tedious, I prefer to read the literature without the lecture

7. jo did he fart at 11:22

8. After mastering a lot of advanced undergrad math, this is easy…
   Whether or not I can take it to the next level depends solely on ME…
   Thoroughly beautiful

9. Idk how i got here, but it was cool to know that i don’t understand anything

10. whatse the meaning of the stupid formalism

11. It's not about MIT
    It's about who is the teacher and who is the student

12. In several lectures, the Professor says that he is going to upload certain material to the course website. Does anyone know how to access this material?

13. Does this series completes the whole general relativity from basic to advanced?

14. I somewhat object to discarding terminology like "covariant" and "contravariant." I agree with your assessment of the value of those terms for understanding the subject matter, but part of your job is to teach these students how to communicate with other professionals in the field.

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

16. Aha.. My wait is over.

17. My dream is to study in MIT, and i hope i would be !

18. 32:50 And what about https://www.youtube.com/watch?v=pTn6Ewhb27k ?

19. I was wondering how come I never saw this course before on YouTube but then I realized it was from Spring 2020. Nice.

20. I wonder why he spends so much time writing on the blackboard? A lot of the stuff he writes seems like it would be better just to show on slides from a computer or overhead projector. Then he could save the blackboard for interactive things where he wants us to see how he thinks, figures things out, etc.

21. 48:50 what a save

22. Another great (and underrated) textbook on elementary GR is J. Callahan's "The Geometry of Spacetime".

23. Hello sir. I am 12 years old and I am learning these great videos, because my dream is to be ASTROPHYSICIST, so I am learning quantum gravity,string theory,thermodynamics, electromagnetism spectrum and relativity. Thank you for your important and great videos🌸🌹

24. So how do the two clocks actually synchronise? If the light is reflected by clock 2 — how does clock 2 sync with clock 1? Or is the pulse not actually reflected, but emitted when the incoming pulse is detected?

25. please update the course for Quantum theory I 8.321 as well we have only lecture notes for that no video lectures

26. I had a dream to be a student of MIT

27. I'm a computer science graduate coming from The Big Bang Theory watching this entire lecture series in COVID-19 lockdown 😛

28. 58:02 – I didn't know Michael Penn was teaching GR at MIT now

29. love from indian village student❤️

30. This course leads to research in black holes, which led to nobel prizes this year… However, a big problem… Stars are not gas balls, thus they cannot collapse into black holes, and black holes will turn out to be total fiction, only an odd mathematical concept. Watch this video and decide yourself why our Sun emit black body radiation, which is impossible if it was purely made of gas plasma. The density of our sun is too high to be entirely made of Hydrogen and Helium plasma as well. https://youtu.be/QDFPx6zVxSw

31. How wonderful that this is free! People in that room pay thousands just to be there but we get to watch it all while being able to pause and rewind the lecture if we need to.

32. The problem is that they should use better tools. Chalk is little bit old now. And there sure are some of the students which will rewrite those in a mich better way of professor’s

33. Ok i take the challenge.

34. last I checked, the speed of light was roughly 300.000.000 m/s not 300k m/s.
    Very enjoyable lecture otherwise, thanks alot for making these publicly available.

35. Why does the professor have to look into his papers so many times even to copy down simple statements on the board ?
    Does not really inspire confidence in his abilities to teach the subject matter. 🙁
    He spends half the time in copying lecture notes on the blackboard and reading them out.
    This is certainly not stuff suited to MIT standards of excellence.

36. Thanks a lot to MIT OCW for posting this course! Btw guys if anyone is interested in learning MIT courses together , for maths and physics you can join a discord server that we created http://discord.gg/KF9tptg

37. How do I watch 8.07- which is the course on Electromagnetism. I really want to get started with relativity here but i read that knowing Electromagnetism is an important prerequisite for this course.

38. is there any student of MIT ?

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

40. 37:23 Mmmm, … speed of light is 29.98 cm/ns. 1 foot = 30.48 cm. Much better than 1% accuracy?
    This is a superb lecture series though!
    Thanks,
    (Still) sneering European.

41. Yes I rather do this than skate or play hockey 😐

42. This vs Frederic Schuller's lecture

43. K
    ok
    Okay

44. Wow quantum relativity in 2021!!

45. Pop quiz: There is a 7-minute 20 second gap between two events in this video. Convert this gap to units of seconds. Now watch the video and then come back here and tell me the what you think – was this gap accidental or a sign of a hidden Controller? https://youtu.be/Rt3EAPDn-Ug Bonus question – what two events in the MIT lecture mark the endpoints for the gap?
