Here’s another great video with Leonard Susskind. In this one Susskind discusses the great problem of time. Even a child knows that there is a difference between the past in the future. In physics, however, it isn’t as simple as that. Most of the equations do not distinguish between the past and the future. Susskind will discuss this peculiarity, as well as the arrow of time and what role it plays in fundamental physics. For more videos check out our full video list.
