**Compressible Aerodynamics Calculator**- Computes the standard relations for compressible flow of a perfect gas. Isentropic flow relations, normal shock relations, and oblique shock relations can be calculated.- Albert Einstein's Analysis of the Brownian Motion - Free e-book by Walter Pfeifer describing the Brownian motion of suspended particles and Albert Einstein's formula.
- An Analytic Solution for the Boundary Layer Equations - Develops a solution for the boundary layer equations in terms of complex variables. From these, a real-valued solution is derived for the boundary layer near a flat plate, showing an exponential rise to the main flow velocity. This solution is shown to have the self-similarity property.
