Nicholas Copernicus Rube Goldberg’s model is overly complicated for completing a very simple task. Occam’s Razor states that the simplest model is usually the best. Here (as, in fact, always) Goldberg fails to develop the simplest possible model. Johannes Kepler From App. D we find: -Least eccentric orbit: Venus (.007) -Most eccentric orbit: Pluto (.248) Using Keplers Third Law (T^2 = r^3): -Venus’ average orbital radius .72 AU r venus^3= .37 = T^2

Unformatted text preview: taking the square root: .61 Earth-years-Plutos average orbital radius: 39.53 AU r Pluto^3=61770= T^2 taking the square root: 248.5 earth-years These answers differ from MotS because we only used 2 or 4 sig figs Galileo Galilei Phases of Venus- Proved Venus went around Sun, not Earth Sunspots- Sun spinning proved Earth could spin Moons of Jupiter- Proved Earth did not have to be center of all revolutions...
