Nondimensional numbers and Similarity [Aerodynamics #4]

In this lecture, we go over non-dimensional numbers and similarity. Non-dimensionlization in aerodynamics and fluid mechanics is a way of thinking relatively, and we continuously compare forces, lengths, etc. to other relevant problem parameters. These non-dimensional numbers continue into Similarity, which is a way of scaling problems and ensuring things stay consistent.
