Quantum Mechanics (QM) is perhaps the most fascinating Physics discovery of the 20th Century. For millenia, most people expected Nature to behave in a similar manner whether you were looking at tiny objects or massive objects. QM shows us how Nature is dramatically different from what our intuition will have us believe.

In this module, we will get introduced to the difference between continuous and discrete quantities. One of the biggest differences between QM and non-QM Physics has to do with QM dealing with lots of discrete quantities. We get introduced to Energy and Spin and how they differ in the QM and the non-QM world
