21: Kepler

Science joke. You should probably move along.

Description

“Kepler” refers to Johannes Kepler, a German mathematician, astronomer and astrologer, best known for his laws of planetary motion. By observing our solar system each night at the same spot, Kepler was able to deduct that planets in the system do not move in a circular direction around the Sun, but rather in an oval way. As you can imagine, this observation was very monotone, and very time-consuming. Hence, if Kepler would have been a cleaner, he'd work consistent and “sweep” the same “area” every night.
