In this video, I introduce spin as a quantum degree of freedom by discussing Stern Gerlach experiment in its most simple terms.
This video explains why spin in quantum mechanics should be thought of as an angular momentum.
I also motivate in what manner Quantum Mechanical spin is strikingly different from classical spin. In the end, I hope to establish a good hold on the fact that spin is an intrinsic form of angular momentum with no classical counterpart (analog).

00:00 Introduction
01:30 Mismatch between theory and experiments
11:07 Spin is not the same as classical rotation
14:15 Basic intro to Stern-Gerlach experiment
16:50 Conclusion

For this lecture series, one is expected to have some basic knowledge of Quantum Mechanics and orbital angular momentum.
