The FBI recovered a 495 year old (!) manuscript signed by Spanish Conquistador Hernando Cortés that was about to be sold at auction in Massachusetts.

Idiot, imbecile, and moron were, not so long ago, used in a psychological classification system, and each one was assigned to a fairly specific range of abilities.
Idiots. —Those so defective that the mental development never exceeds that or a normal child of about two years.
Imbeciles. —Those whose development is higher than that of an idiot, but whose intelligence does not exceed that of a normal child of about seven years.
Morons. —Those whose mental development is above that of an imbecile, but does not exceed that of a normal child of about twelve years.
— Edmund Burke Huey, Backward and Feeble-Minded Children, 1912 -

The Stipa-Caproni was an experimental airplane designed by the Italian aeronautical engineer and aircraft designer Luigi Stipa, and built by Caproni, an Italian aircraft manufacturer. Despite looking like a cartoon air plane, the Stipa-Caproni could fly, and was briefly studied by NASA.

This would make a useful topic for a physics question from hell! Try and derive an equation to describe the position of the ball over time.....
