Physics Explained is a channel that explores advanced topics in physics without skimping on the mathematical detail. There is a growing community of independent learners who are keen to explore modern ideas in physics with the aid of mathematical reasoning. This channel aims to tackle advanced topics head on whilst at the same time providing a historical narrative to help provide context to the ideas. A bit about my educational background: I have a PhD in theoretical physics, specialising in string theory. I now dedicate most of my my time to physics education.

Video Description
This video provides a basic introduction to the Schrödinger equation by exploring how it can be used to perform simple quantum mechanical calculations. After explaining the basic structure of the equation, the infinite square well potential is used as a case study. The separation of variables approach is used to solve the Schrödinger equation and Born's probabilistic interpretation of the wave-function is used to calculate the expectation value of the position of a particle in a box. Stationary states are discussed, and it is shown that a linear superposition of energy eigenstates leads to non-stationary states with uncertain energy. The oscillation frequency of a simple superposition of states is calculated and comparisons with radiation emission from atoms is discussed.
