Rocket science seems simple today, by comparison of other more-complicated technologies. Using computer modeling and calculation, we can accurately predict probable trajectories in which an object will travel. But it wasn't always this way. For a long time, we were trying to figure out how to measure the speed of gravity with blackboards and pocket-watches. Figuring out "who likes cake vs who likes pie" seems simple, yet we still wrangle with it.
