What an amazing lecture, especially the last hour when he opens the floor. IMO this was the most entertaining and deep lecture of Stanford physics I've watched so far.
I've watched nearly 3/4 of all of Professor Susskind's lectures... I dropped out of highschool when I was young and am preparing myself for college by learning calculus, physics, and watching videos like these. Things are 100 times easier to understand because of this man. THANKYOU STANFORD! THANKYOU LEONARD SUSSKIND!
@aqouby "I dropped out of highschool when I was young and am preparing myself for college"
You might find MIT's physics 8.01, 8.02, and 8.03 more helpful for this purpose. String Theory is unlikely to appear on the entrance exam. And Walter Lewin is an excellent lecturer. I'll refrain from comparing him to Susskind on that front, since I usually get modded down for doing it. (But Lewin is a hell of a lot better.) I've put up a playlist of the 1st 6 lectures of 8.01 on my channel page.
@csmcmillion His gift is a deep dedication to teaching combined with a lot of ongoing hard work. Search YT for "The Wonder and Beauty of Teaching Physics" if you've not already seen it. Also, he has a new book out: "For the Love of Physics". Regarding Lewin as physicist, WP has a list of some of his papers. His Ph.D. is in nuclear physics. Most of the papers are on astrophysics. I'd love to see him do a course on an astrophysics subject. Though I'm still working through the MIT 801.3 course.
There's one thing I don't get: in deSitter space Susskind says the horizon is hot so if you let a thermometer down to the horizon and pull it back, it shows a high temperature. But IMHO from the perspective of the thermometer it's not his horizon, so it should not see a temperature rise. It's different if you measure the temperature from your point with photons where the wavelength has to fit into the distance between the object and the horizon and therefore has to be very short i.e. hot?
Could quantum mechanics represent the passage or Arrow of Time?
This theory is based on just two postulates,
1.The first is that the quantum wave particle function explained by Schrödinger’s wave equation represents the forward passage of time or Arrow of Time itself photon by photon, quanta by quanta or moment by moment.
2. The second is that Heisenberg’s Uncertainty Principle that is formed by the wave function is the same uncertainty we have with any future event.

Ha ha, now I`ve seen all lectures starting from classical mechanics !
10^500 thanks to Prof. Lenny Susskind and Stanford :-)))
Cheers

What is all this talk about black bodies? How racist.

@sbergman27 Yes, I've watched his lectures as well. Thanks for the advice, he is an amazing lecturer. :D

Susskind: Gifted physicist, decent teacher
Lewin: Decent physicist (?), gifted teacher

Fascinating stuff.......I am really sorry to see it end. Can we expect more from
Prof. Susskind?
