In the fourth lecture, Harvey Brown asks why real-world events always proceed in the direction of increasing entropy, even though the laws of physics don’t require it.
The Probability Puzzle
In the third lecture, David Wallace asks how we make sense of probability in the Many-Worlds theory.
An examination of some more advanced concepts of quantum mechanics, focusing on describing Dirac's bra-ket formulation of quantum theory. I discuss the formulation of quantum mechanics in terms of vectors in Hilbert spaces, Hermitian operators as corresponding to observables, ort ...Show more
Dr Scott Aaronson (MIT, UT Austin) gives the 2016 Strachey lecture. In the near future, it will likely become possible to perform special-purpose quantum computations that, while not immediately useful for anything, are plausibly hard to simulate using a classical computer. These ...Show more
