Time is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away. ~Marcus Aurelius Antoninus
1836 – Samuel Colt is granted a United States patent for the Colt revolver.
Samuel Colt was an American inventor and industrialist from Hartford, Connecticut. He founded Colt’s Patent Fire-Arms Manufacturing Company (today, Colt’s Manufacturing Company), and made the mass production of the revolver commercially viable.
Colt’s manufacturing methods were at the forefront of the Industrial Revolution. His use of interchangeable parts helped him become one of the first to exploit the assembly line. Moreover, his innovative use of art, celebrity endorsements and corporate gifts to promote his wares made him a pioneer in the fields of advertising, product placement and mass marketing, although he was criticized during and after his life for promoting his arms through bribes, threats and monopoly.
1866 – Miners in Calaveras County, California, discover what is now called the Calaveras Skull, human remains that supposedly indicated that man, mastodons, and elephants had co-existed.
The Calaveras Skull was a human skull found by miners in Calaveras County, California which was purported to prove that humans, mastodons, and elephants had coexisted in California. It was later revealed to be a hoax. Coincidentally, “calaveras” is the Spanish word for “skulls”.
On February 25, 1866, miners found a human skull in a mine, beneath a layer of lava, 130 feet (40 m) below the surface of the earth, which made it into the hands of Josiah Whitney, then the State Geologist of California as well as a Professor of Geology at Harvard University. A year before the skull came to his attention, Whitney had published the aforementioned belief of humans, mastodons, and elephants having coexisted and the skull only served as proof of his convictions. After careful study, he officially announced its discovery at a meeting of the California Academy of Sciences on July 16, 1866, declaring it evidence of the existence of Pliocene age man in North America, which would make it the oldest known record of humans on the continent.
However, its authenticity was immediately challenged. In 1869 a San Francisco newspaper reported that a miner had told a minister that the skull was planted as a practical joke. Thomas Wilson of Harvard ran a fluorine analysis on it in 1879 (the first ever usage of such on human bone), with the results indicating it was of recent origin. It was so widely believed to be a hoax that Bret Harte famously wrote a satirical poem called “To the Pliocene Skull” in 1899.
1933 – The USS Ranger, the first ship to be built solely as an aircraft carrier, is launched.
USS Ranger (CV-4) was the first ship of the United States Navy to be designed and built from the keel up as an aircraft carrier. Ranger was a relatively small ship, closer in size and displacement to the first US carrier—Langley—than later ships. An island superstructure was not included in the original design, but was added after completion. Of the eight pre-war US aircraft carriers CV-1 through CV-8, Ranger was one of only three to survive World War II, the others being Enterprise and Saratoga. Deemed too slow for use with the Pacific Fleet’s carrier task forces, the ship spent most of the war in the Atlantic Ocean.
Ranger was laid down on 26 September 1931 by the Newport News Shipbuilding & Drydock Co., Newport News, Virginia, launched on 25 February 1933, sponsored by Lou Henry Hoover (the wife of the President of the United States), and commissioned at the Norfolk Navy Yard on 4 June 1934, with Captain Arthur L. Bristol in command.
1971 – The first unit of the Pickering Nuclear Generating Station, the first commercial nuclear power station in Canada, goes online.
Pickering Nuclear Generating Station is a Canadian nuclear power station located on the north shore of Lake Ontario in Pickering, Ontario. The facility derives its name from the City (originally Township) of Pickering in which it is located. It produces 15-20% of Ontario’s power.
Co-located at the Pickering station is a single 1.8 MWe wind turbine named the OPG 7 commemorative turbine.
2012 – Adafruit in the New York Times – Wearable Electronics Are Making a Statement
If you want to try your own hand at creating a computerized, electronic glow, Adafruit Industries, a New York company that makes and sells kits and components, will soon introduce a small, wearable microprocessor called Flora to control LEDs or other electronic adornments. Becky Stern, who leads the company’s wearable electronics group, will develop projects and kits based on it for crafters. “Pop stars have costumes made by ateliers at huge cost,” Ms. Stern says, adding that her company’s products would “let you make these electronic wearables at home for a fraction of that.”…
Ms. Fried at Adafruit says she looks forward to a time when people will routinely modify the style of their shoes, jackets, T-shirts or handbags with circuitry. Then, she says, Bill Cunningham, the fashion photographer for The New York Times who has long roamed the streets for the latest looks, will have a new trend to cover: LED fashions.
In his ongoing effort to make New York City a technological powerhouse, Mayor Michael Bloomberg today revealed the 20 middle schools and high schools picked for the city’s new Software Engineering Pilot (SEP) program.
As part of the program, the schools will get “comprehensive computer science and software engineering curriculum” for around 1,000 students. The program will launch this September and is expected to grow to 3,5000 students by 2016.
