Fun Fact December 28, 2020.

28 December 2020

It’s a quick fun fact today, as a matter of fact we’ll do it in a jiffy!  According to Dictionary dot com The expression in a jiffy was in use as early as 1780 and is an expression for “in a short amount of time.”  The origins of jiffy are unknown, but one theory suggestions it comes from British thieves’ slang for “lightning,” hence very fast. An early instance appears in 1780 edition of Town and Country Magazine: “Most of the limbs of the law do every thing in a jiffy…”  Jiffy was shortened to jiff as early as 1791. Jiffy is much more common, however.  How long is a jiffy?  Scientist Gilbert Newton Lewis, in the late 18th century, defined a jiffy as the amount of time it takes light to travel one centimeter in a vacuum, about 33.4 picoseconds, or about one trillionth of a second.  In Britain a jiffy is a padded envelope and here is the U. S. we have Jiffy Lube for a fast oil change.
