I love the way Susskind talks about physics and even just talks in general. His background as a plumber I feel is a boon to the communication of physics; talking to people like they are a normal joe and a potential scientist. Everyone can have access to these ideas. And they can be simple and elegant.

this guy is just incredible he's moving from calculus, probability, topology, classical mechanics, thermodynamics etc at will using just words

@@niamcd6604 The issue for me isn't that their not precise enough. It's that they try to fit too much into a lecture an hour or so long. If I try to understand an example that they work through in full mathematical detail by the time I have understood everything, they have covered the next 1 or 2 slides or are half way through the next example problem. Videos are much better for me because I can pause and rewind whenever I need to. Zoom classes are the worst of both worlds because you get none of the benefits of videos and it is subpar compared to attending in person. That's why if I ever become a teacher I'm going to create a You tube channel, so students can watch my lectures at their own leisure before or after class.

I just studied the quantum mechanics course and this looks even better :). I love the probability part, particularly the classes in the Markov chain as a conservation law. Is the relation between time spent at each state and probability a sort of baby ergodic theorem?

Ever since Gus Fring died, Mike Ehrmantraut has had to take up a side gig teaching statistical mechanics to make ends meet.

1:30:20 "Two is the smallest number which is not one" I really like this statement.

Just bought the classic text, The Principles of Statistical Mechanics by Tolman with so much excitement. And, it’s a hardback version from the 40’s! S. Chandrasekhar once recommended the text to his brother to study for physics. You can just sense that this is a master text. A subject that gives you the power to analyze mechanical systems when their initial states are known only partially ? Count me in.

I have seen the complete set of videos Statistical Mechanics by Susskind. I can highly recomend the book "Fundamentals of Statistical and Thermal Physics" by F.Reif. It is Briljiant together with Lennys vidoes.

I wish I could ever get a chance to take a part in this kind of lecture in Stanford

his examples and analogies, uffff! , how does he come up with such great ideas...

If he is right and statistical mechanics is the deepest aspect of physical reality, then I'd vote for Stirling's/de Moivre's approximation over Pythagoras' theorem or Euler's formula as the most important _practical_ result in all mathematics. Thanks Lenny.

This professor is just the best!

at 1:13:20 professor Susskind says that temperature is a highly derived quantity "despite the fact that you feel it with your body", so he points out the contradiction of how temperature feels intuitive despite being a more mathematically-derived concept with respect to more primitive concepts like energy. the thing is, in fact, you don't feel temperature at all, you feel THE FLOW OF THERMAL ENERGY. if i'm not mistaken minutephysics has done a video about it too.

This is why the tution fees is extremely huge in comparison to my college I went. Nice lectures, challenging and optimistic preparing your brain to utilise the potential.

That casual definition of a conservation law as the possibility space dividing up into cycles went by so quickly it didn't blow my mind until I rewatched.

In many cases what separates the average student an elite university from the average student at a good state university is not necessarily that the former has vastly superior intellectual capabilities (although that is often true of their *best* students), but that elite university students have demonstrated great ambition and an incredible work ethic. The content of the classroom lectures is likely very similar, though the volume and difficulty of the problem sets and course projects is probably substantially different. My own experience in taking and teaching courses as an undergraduate student at a good private university and a graduate student at a borderline-elite technical university was that the student bodies weren't that different entering as freshman, but that by graduation the latter were better at their craft due to the sheer volume of work completed during 4 years of frequent sleepless nights and the constant struggle to meet impossible deadlines and expectations. It's certainly not for everyone, nor should it be. Many people aspire to obtain a stable, moderately high-paying job in an enjoyable profession, and to that end many universities will do a great job. The advantage of elite universities is building a network of people who will rise to high positions in society, as well as being surrounded by a culture which not only aspires to excellence, but demands it on a daily basis.

@Nuclear Nadal I can go along with some of what you said except the part about sheer volume of work, impossible deadlines and sleepless nights. Give me a break. All college students go through that, not just the ones at elite universities. I sure did. I often wonder how my collegiate effort would have been received at an Ivy League institution, I always did whatever it took to make the grade. The coursework is harder you say? Well, I wouldn’t know but I’m sure even students at elite universities open their intermediate macroeconomics with calculus applications text books and have a good cry. My major was no picnic and I had some very bright classmates who were also pushed to their limits. A lot of us including me turned down admissions from more competitive institutions because our money went further elsewhere, not because we couldn’t gain admission. I turned down Rice and a classmate of mine declined the U. of Chicago. It’s just tough for me to imagine I would have put any more effort into my studies than I did. I’ll never know. Things are great for me. Over 30 years I’ve built a strong professional and social power base. Almost all of my friends are the same. Anyway, I’ve never regretted the decision I made.

For example, if you select a random number between 0 and 1, the total number of cases is infinity. Therefore, the probability to get exactly i = 0.5 (for example) is 1/infinity = 0. You are correct about the PDF. I had a long paragraph together with this sentence; however, I decided to erase the paragraph. This little sentence, out of the context, was forgotten in the purge.

Very nicely explained. Easy to be good with such preparation and knowledge to impart.

I had to watch this bc it has 666k views and I can never say no to hearing Mr Susskind lecture

Amazing lecture, this will be my subway playlist!

Beautifully explained!

Mathematicians invented and often manipulate the dirac delta function and it does appear in physics quite a bit e.g. the probability density function of photons of different frequency having their energy absorbed by a bound electron.

these lectures should be saved in a museum and protected for posterity. they are like a treasure of mankind

About the evolution of the states of the colours, where they evolve each microsecond, surely how often the observations take place will determine the outcome, if you measure each 6th microsecond you will get one answer all the time and conclude 100% probability of some colour, in fact, depending on frequency and the phase of your observations the outcome will vary, you would either need a very fast rate of observation or a completely random sequence of observations as to not bias the results

May I ask what was the textbook the video learning?

Perhaps they approach infinity together, but at some fixed ratio to one another? For example, as the number of coin flips approached infinity, the number of heads results might also approach infinity, but at a rate half the total. I imagine N(heads) = N/2, so N(heads)/N = N/2N = 1/2.
