In this video I discuss the relationship between momentum, velocity, and position. The phase and group velocity are discussed. The momentum space representation of the wave function is derived and is shown to be related to the spatial representation of the wave function through a Fourier transform. The resulting coupling between the uncertainty in momentum and position is examined. This is video 5 of the X part series.

In this video I demonstrate how to solve the particle in a 1D box with infinite boundary potentials. Separation of variables is used allowing the spatial and temporal variables to be solve independently. The particular solution is used to express the general solution. The coefficients in the general solution are determined from an initial condition at t=0. The implication of the solution, as it pertains to the statistical interpretation of quantum mechanics is discussed. This is video 4 of the X part series.

In this video I discuss the four fundamental postulates that underly quantum mechanics. We look at the implications of these postulates on the statistical interpretation of quantum physics. This is video 3 of the X part series.

In this video I discuss the Stern-Gerlach experiment as it relates to the fundamentals of quantum mechanics. This is video 2 of the X part series.

In this video I discuss the history of quantum mechanics. This is video 1 of the X part series.
