How to Think Like an Engineer would be the course I’d like to do the most. I know that doesn’t sound like an exciting course to a lot of people, but there’s a lot of people out there and they learn only by repetition and I find that quite sad. In the past we had people like Isambard Kingdom Brunel or Robert Stevenson, they didn’t have huge teams of people to design bridges and ships and tunnels. They did it all themselves using back of the envelope equations. If you take Brunel, he designed the first iron-hulled, coal-fired ship to cross the Atlantic. If he can do all that with that knowledge that he had over a hundred years ago, basic engineering mathematical scientific principles, then surely we can teach people in a course how to do that today.
