How to Get Classical Physics from Quantum Mechanics
We tend to think of Classical Physics as straightforward and intuitive and Quantum Mechanics as difficult and conceptually challenging. However, this is not always the case! In classical mechanics, a standard technique for finding the evolution equations for a system is the method of least

Variation of Parameters for Systems of Differential Equations
This is the second part of the variation of parameters-extravaganza! In this video, I show you how to use the same method in the last video to solve inhomogeneous systems of differential equations. Witness how linear algebra makes this method so elegant!

Time-Independent Schrödinger Equation | Quantum Mechanics
In this video, we will talk about the time-independent Schrödinger equation in quantum mechanics. If we start with the time-dependent Schrödinger equation, we can get to the time-independent one by performing a separation of variables on the wave function, where we claim that the time depe

Variational Methods | Quantum Mechanics
In this video, we will discuss variational methods, in particular the Ritz method for approaching the ground state energy of a system. If we look at a quantum mechanical system with Hamiltonian H, we always want to know: what's the ground state energy? Because that's the energy that the
