Clocks

Clocks By Sydney

B.C. 742 First authentic recorded mention of the sun dial. There is, however, evidence of use of the sun dial as early as 2,000 B.C. B.C. 300 Toothed wheels for transmission of power attributed to Archimedes. A.D. 330 Sand glasses known to be in use. Alfred the great used candles as "clocks." Clock making in England started. Mainspring invented by Peter Hele, or Henlein, a locksmith of Nurnburg. About this time the small domestic, or table clock made its appearance. The first watch was made at about this time. Screws made their appearance. An astronomical clock was fixed in one of the towers of Hampton Court Palace. Galileo, Italian Astronomer and Physicist, dis covered the properties of the pendulum. Watchmaking industry commenced in Geneva. Glasses as protection for watch dial and hand introduced. Enamel dials invented by Paul Viet of Blois, France. Christiaan Huygens, a Dutch Physicist, made the first pendulum controlled clock. The recoil anchor excapement, possibly invented by Dr. Robert Hooke between 1666 and 1667. Pendulum suspension spring introduced by William Clement. The first known clock with anchor excapement made by William Clement. Royal Observatory at Greenwich founded. Edward Booth ( Later Rev. Edward Barlow ) invented the Rack Striking Mechanism for clocks. The concentric minute hand, with motion work similar to that in use today, was used by Daniel Quare, a famous London maker and others. Daniel Quare also made repeating watches about this time. The Second Hand is introduced. Nicholas Facio, FRS, a native of Geneva, who settled in London, succeeded in piercing rubies and sapphires for use as jewelled bearing for balance staff pivots. George Graham invented the dead-beat excapement for clocks. He also invented the mercurial compensation pendulum. John Harrison invented the grid-iron compensation pendulum. George Graham invented the cylinder escapement. Centre Seconds hand introduced. " Tell-tale" clocks invented by John Whitehurst, FRS, a celebrated clockmaker of Berby and London. (1713-1788) Alexander Bain, an Edinburgh clockmaker, made the first electric clock. The British Horological Institute, an association of Clock and Watch Makers for the purpose of advancing the horological art, was founded. "The Horological Journal," the oldest periodical dealing with the craft, was stated. Georges Frederick Roskopf developed the pin pallet escapement. G.M.T. became the standard time for the whole of the United Kingdom. Charles R. Sligh forms theSligh Furniture Company The meridian of Greenwich was adopted by international agreement as the zero or prime meridian from which the longitude of all places in the world is measured. The first electric master clock and impulse dial system was invented by Frank Hope-Jones, F.B.H.I. Upon which all modern impulse clock systems are based. Electric contacts are fitted to a Marine Chronometer for the purpose of impulsing secondary dials. Summer Time first introduced. The alternating current synchronous motor was first applied to clocks by H.C. Warren in the U.S.A., although the principle had been discussed as far back as 1895. Study and development of the Quartz Crystal clock commenced by Dr. Warren A. Marrison, F.B.H.I. a Canadian who became an American citizen. Howard C. Miller starts the "Howard Miller Clock Co." Quartz Crystal clocks introduced at the Royal Greenwich Observatory.

Clocks help our life and the world around us by letting us know what time it is. Clocks are actually a form of math/ measurement because you measure the time.

 * || [|John Harrison was born in 1693 in Yorkshire and was the son of a poor carpenter. He became fascinated by watches at the age of 6, when he fell ill with smallpox and was given one by his parents. He eventually learned how to make and repair clocks, and started to improve upon how they were built. One of Harrison’s innovations was a pendulum resembling a gridiron that was made out of alternating steel and brass rods. Another was the “grasshopper” escapement, which is a device used to control the release of a clock’s driving power. In 1735 he finished his first version of a marine clock to be used at sea. After working on several improved versions, he was awarded 20,000 pounds by Parliament as part of a competition to find a way to establish longitude while at sea. Harrison became known as “Longitude Harrison” for his achievement.] ||

An African American named Benjamin Banneker invented the [|clock] around the year 1750 when he was just 21 years old. He saw a famous u.s surveyor with named Andrew Ellicott who had a pocket watch which amazed benneker. Andrew ellicott gave the pocket watch to banneker and banneker invented the clock, a bigger version of a watch. Ellicott's brother joseph wanted banneker to build a clock to determine the correct calculations of stars in the sky. In otherwords, joseph ellicott was into [|astronomy]. http://www.blurtit.com/q292382.html Daylight saving time (DST) ends at 2 a.m., local time, on Sunday, Nov. 7. Most U.S. residents will dutifully set their clocks back one hour before they go to bed on Saturday night. People in most of Arizona, Hawaii and in the U.S. territories of American Samoa, Puerto Rico and the Virgin Islands, however, will leave their clocks alone. These locations never sway from standard time within their time zones. http://www.findingdulcinea.com/news/Americas/2009/October/Daylight-Saving-Time--Don-t-Forget-to-Change-Those-Clocks.html

The Lede’s approach followed the format of another Times blog, The Caucus, which covered the 2008 presidential election in a similar manner, often breaking headlines before the actual paper did.

Dubbing citizen journalists “the people formerly known as the audience,” Rosen argues that this group simply isn’t “on the clock ” of the mainstream media anymore. “We graduate from wanting media when we want it, to wanting it without the filler, to wanting media to be way better than it is, to publishing and broadcasting ourselves when it meets a need or sounds like fun.” He adds that citizen journalism is something that MSM executives, including News Corp’s Rupert Murdoch, Reuters’ Tom Glocer and the BBC’s Mark Thompson, are embracing, and are willing to cater to.  ||
 * || IReport is a CNN sister site that is solely user-generated. On it, regular  people can create accounts in seconds and start posting articles, blog entries and comments to others’ work. CNN includes some of these reports on its Web site and on television, “vetting” the content it chooses. None of the other content is “edited, fact-checked, or screened” before appearing on the site. In the “About” section of iReport, the mission is described thus: “Lots of people argue about what constitutes news. But, really, it’s just something that happens someplace to someone. Whether that something is newsworthy mostly depends on who it affects—and who’s making the decision.”

Hawking is a cosmologist and the bestselling author of “A Brief History of Time .” The gold clock  makes use of six patented inventions, a swinging pendulum, and its most startling feature—a blinking, lizardlike beast crouched on top that is meant to symbolize the devouring of time . The mechanism, which consists of traditional clockwork and no digital parts, took seven years to research and build, and it is estimated that it will run for at least 250 years. “It is terrifying, it is meant to be,” said Taylor in an interview with the Guardian. “Basically I view time  as not on your side. He’ll eat up every minute of your life, and as soon as one has gone he’s salivating for the next. It’s not a bad thing to remind students of. I never felt like this until I woke up on my 70th birthday, and was stricken at the thought of how much I still wanted to do , and how little time  remained.” Taylor is an inventor whose creations include a thermostat switch that is used in electric kettles. He says that Harrison, a clockmaker who discovered a method to establish longitude at sea, is one of his heroes. In 2006, Harrison’s last masterpiece, the Late Regulator <span class="yo_hl1 yo_ohl1">clock  was restored more than 230 years after the death of its maker. Harrison had worked on the <span class="yo_hl1 yo_ohl1">clock  for 36 years and was still calibrating it when he died.  || http://www.google.com/images?hl=en&biw=1053&bih=544&gbv=2&tbs=isch%3A1&sa=1&q=Clocks&aq=f&aqi=g10&aql=&oq=&gs_rfai=
