Tech Origins

Sunday

“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.

Monday

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, all while sporting 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.

Tueday

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.

Wednesday

Apple co-founder Steve Jobs came up with the name after returning from an Oregon apple orchard. He thought the name sounded “fun, spirited and not intimidating” and was also on one of his “fruitarian” diets at the time. An added advantage: the “A” word would be closer to the front of the phone book.

Thursday

Twitter founders originally considered the names “Status,” “FriendStalker,” “Vibrate,” and “Dodgeball,” but a dictionary search encountered the word “twitter” and a definition of “a short burst of inconsequential information; chirps from birds,” which sounded spot-on. It was initially called “twttr” in the mold of flickr, but reverted back to Twitter later.

Friday

Originally called “The facebook,” Facebook’s name came from the the list of student and staff directory and profiles which freshmen at founder Mark Zuckerberg’s then-school Harvard were given.

Saturday

Craigslist is named for founder Craig Newmark, who started the site in 1995 as a hobby after emailing some dozen friends about interesting San Fransisco happenings. As more people asked to be added to the listserve and asked for info on other things, including tech jobs, he created the site.

The Basics

Sunday

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.

Monday

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.

Tuesday

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.

Wednesday

Water is not blue because it reflects the sky, but appears blue for a similar reason that that sky does. The water absorbs long-wavelength yellow, orange and red colors and reflects short-wavelength colors, mostly blue. Since blue is the color reflected back to our eyes, we see the water as blue.

Thursday

This same reason our sky appears blue also explains the sun’s appearance from Earth. Our sun is white when seen from space, but our atmosphere scatters the sun’s shorter-wavelength blue / indigo / violet-range colors such that longer-wavelength red / orange / and yellow colors within sunlight reach us more easily, and the sun usually appears as one of these colors.

Friday

Incoming light refracts within water droplets while they’re in the air to separate the colors which compose white light, all of which move at slightly different speeds. With the droplets acting like a prism and a color separater, we can then see those individual colors as a rainbow. In addition to familiar rainbows, there are also “moonbows” and “fogbows.”

Saturday

Hair follicles produce less color as they age, and the result is that your hair eventually appears white with no color to change it…unless you add some from a bottle. However, genetics and disease also play a role in hair color.
