This 1943 advertisement for the Connecticut-based Traveler’s Insurance Company argued that since even the brilliant scientist Aristotle could make false predictions about gravity, everyone needs to buy travel insurance to forestall unpredicted events. He is depicted lecturing in the Lyceum, making the claim, stated in his On The Heavens¸ that "If a certain weight moves [falls] a certain distance in a given time, a greater will move the same distance in a less time, and the proportion which the weights bear to one another, the times, too will bear to one another”.
Galileo famously disproved this in around 1590 by dropping two balls of different weights off the Leaning Tower of Pisa. They landed at the same time. But in 1987 an article published in the European Journal of Physics proved that at T>0 heavier and/or colder objects actually fall faster than their lighter and/or warmer counterparts. This unexpected result was demonstrated using elementary quantum mechanical arguments. Aristotle was partly right, after all.
