Enough Alredy

Since the color red has been associated with communism since the 20th century, the expression “Better dead than red” connotes a firm rejection of communism, while “Better red than dead” showed more compromise, especially among Cold War-era opponents of nuclear weapons.

The first reference to a “red hand,” which you have when caught red handed, comes from a Scottish law from 1432. Unsurprisingly, the red was blood, which came from murder or poaching.

Did you ever “paint the town red” on some wild night? The likely origin of this one is fairly literal. Notorious drinker and hellraiser Marquis of Waterford led his drunken buddies through the town of Melton Mowbray in England one night in 1837, and after breaking windows and flowerpots, the raucous crew procured some red paint and redecorated several doors, a tollgate, and a swan statue. Once sobered up, they had to compensate the damaged town.

Let’s Get Crazy

For centuries, doctors associated insanity and other medical afflictions with lunar cycles, hence the terms “lunatic” and “lunacy” to describe an affected person.

Since most nuts, like the human head, are hard with valuable contents, people have used “nut” as slang for “head” since at least the mid-1800s. The term “off his nut” described someone who seemed separated from his head and senses, and this was later shortened to just “nuts.”

An unpredictable and dangerous person is sometimes called a “loose cannon.” Early cannons of the wooden ship days were not yet secured in fixed spots, but were wheel-mounted and could be rolled to different gunports on the ship. When one of these extremely heavy guns broke loose on deck during high waves or battle, the “loose cannon” was a clear danger to nearby crewmen.

Old In the New Tech

“Google” is a misspelling of the number called “googol,” which is a 1 followed by one hundred zeros. The search engine was named for this huge number to indicate it’s intention to search through immense amounts of information, which it certainly does.

Your Bluetooth devices are named for a 10th Century viking king who needed a dentist. Harald Gormsson was a Scandinavian ruler who united Denmark and Norway, but who also sported a prominent dead, dark blue-grey tooth that earned him the nickname “Bluetooth.” Early Bluetooth engineers, seeking to “unite the PC and cellular industries with a short-range wireless link” used the name in honor of this uniter king, but it was only meant to be temporary. When the other proposed names for the technology were found to be trademarked or weren’t trademark searched at all, only “Bluetooth” was left for the upcoming launch. What’s more, the Bluetooth logo is the old king’s initials as written in ancient Danish runes.

The term “yahoo” was first coined by Johnathan Swift in his 1726 book “Gulliver’s Travels.” The yahoos were a primitive humanoid race, “brute[s] in human form,” who also happened to be ruled by a race of super-intelligent horses. The modern search engine’s name is an acronym for “Yet Another Hierarchical Officious Oracle,” but Yahoo creators also chose the name because they liked it’s uncouth connotation from Swift’s book.

The Basics

The sky is blue because of basic physics. The sun shines all the colors of visible light on the Earth, but the color we see as blue is made of the shortest, smallest wavelengths. For this reason, it scatters the most when hitting air molecules in our atmosphere, making the sky appear as blue due to the greatest scattering of blue’s short wavelengths.

Your blood is red because of iron and oxygen. Within your red blood cells is hemoglobin, a protein made of an iron-based compound called heme. Heme binds with the oxygen you breathe, and the oxygen-iron bond reflects light to appear red. Elsewhere in the animal world, blood can be yellow, green, blue, or purple, and in the “Star Trek” universe, Mr. Spock’s is green, because Vulcan blood is copper-based rather than iron-based.

Grass is green because of chlorophyll. Grass, plants, trees, algae, and even some bacteria have the impressive ability to make their own food out of sunlight, water, and carbon dioxide. The pigment that does this work is chlorophyll, which reflects green light and so appears green to us.
