> "What we saw is that Leonardo wrestled with this, but he modeled it as the falling object's distance was proportional to 2 to the t power [with t representing time] instead proportional to t squared," Roh says. "It's wrong, but we later found out that he used this sort of wrong equation in the correct way." In his notes, da Vinci illustrated an object falling for up to four intervals of time—a period through which graphs of both types of equations line up closely.

All lines look straight if plotted on a log-scale and drawn with a thick enough marker.

Compare 2^t, where t takes values from [1, 2, 3, 4], with t^2 over the same set of values. The results are closer than you might expect.
