  • I think the cockie eating is OK. It makes the class more informal and relaxed, as it should be. He's transmitting knowledge, and he obviously enjoys doing it. Why not making the experience even more confortable with some coffee and coockies.

  • @rax7 Hey, it's California; and it's college, not high school. (And I think it's continuing education?)

  • Good, I like that you share this video, I wish success always Leonard Susskind lectures on harmonic oscillators, quantum states

  • @PeaceWithTheseEyes lol What?? This is statistical mechanics, not poetry class.

  • Damnit man! I was expecting a cookie and you never seem to fail me.

  • A young journalist is threatened by an army of spies when she stands before the secret behind Quantum Energy.

  • Leonard Susskind is a forgetful old man but he is a guru on physics. He doesn't forget anything about the subject. He's great!

  • @rax7 It is a continuing ed class taught in the evenings. The audience is made up of other adults. It is dinnertime and I'm sure all are hungry and tired, so I'm sure a lot are snacking and drinking coffee. In fact, the person who brings the snacks has much more than a few cookies - perhaps enough for the class to share?

  • wow what an honor it would be to be lectured by Leonard Susskind!

  • Planck's derivation is not magical or incomprehensible. His starting point is that the energy levels are quantized: E=ne. Using boltzmann statistics he calculates the average energy of each wall oscillator - that was his concept - in the black box. Then he requires that the total energy density for all oscillators must satisfy the stefan-boltzmann law. This can only be if e=w. That's it. There's nothing magical or incomprehensible about it.
