“ This is a short little book— 176 pages total— built around the idea of Fermi Problems, the order-of-magnitude estimates that Enrico Fermi was famous for. The idea is that, with a little basic knowledge and some really simple math, you can come up with ballpark estimates of all sorts of things— the canonical Fermi problem example is “How many piano tuners are there in Chicago? ”
Those demonstrations, though, do not allow for side-by-side comparison of the effects of various launch angles. Thus, a few years ago I constructed this three-dimensional projectile model to do just that. The model is composed of two three-dimensional “stroboscopic sculptures” representing the trajectory of two projectiles. (via Projectile Motion Model)
