Fun Fact 15 :)

A "jiffy" is about one trillionth of a second.

According to Dictionary.com, a "jiffy" is an actual unit of time—and a very short one at that. Sometime during the late 18th or early 19th centuries, scientist Gilbert Newton Lewis defined a jiffy as the amount of time it takes light to travel one centimeter in a vacuum, which is about 33.4 picoseconds or one trillionth of a second.
