video Discussion 1 - a random walk from stochastic to quantum mechanics
Density is evaluated in configuration space, but the Laplacian is diagonalized in the Fourier space; a random walk from stochastic to quantum mechanics; Wiener path integrals; Schr{\"o}dinger harmonic oscillator is imaginary time relative of the Ornstein-Uhlenbeck; Liouville theorem; Predrag's lecturing is a Gaussian process - on average you learn zero.
