Want to solve differential equations? Think about how you ride your bike
If you’re serious about modeling, you’ll need to understand how the engine solves differential equations sooner or later. So the next time the engine does something strange, you’ll know what to look for.
Most people, I believe, are like me in that they cannot derive their intuition from equations; it … Read the rest
