When researching for the article I was actually rather surprised that I couldn't find many MOOCs on aeronautical, civil, electrical, chemical or mechanical engineering.

While it's pretty straightforward to find open courses/content on Linear Algebra and Calculus, there's very little on, say, Compressible Flow/Gas Dynamics or Turbomachinery, for instance.

If anybody knows of any courses on topics related to the above engineering disciplines, I'd love to take a look.

I also agree that at the end of part 2, one would have sufficient "mathematical maturity" to handle most commercial environments.
