Who invented the Traffic Light????????
537407
(m)\n\n\n\nThe very first traffic light was a revolving gas lantern with red and green lights installed in a London intersection in 1868, before the advent of automobiles. A later version of the traffic light based on railroad signals was installed in Detroit, Michigan, in 1920. But we have Garrett Augustus Morgan to thank for the modern version and first patent of this traffic-stopping invention. \n\nThe son of former slaves, Morgan was born in 1877 in Kentucky. He later moved to Cincinnati and then Cleveland, where he owned and operated a sewing-machine repair business and earned quite a reputation as a technician. A multi-talented businessman, Morgan went on to establish the newspaper The Cleveland Call. \n\nIn early 20th century Cleveland, as in other major U.S. cities, the roads were clogged with pedestrians, bicycles, animal-drawn wagons, and those newfangled automobiles. There were no traffic laws to speak of, and chaos ruled the streets. Accidents were frequent. After witnessing one such traffic accident, Morgan felt compelled to improve the situation. The result? The precursor to the modern traffic signal, patented on November 23, 1923. \n\nThe world’s first traffic light came into being before the automobile was in use, and traffic consisted only of pedestrians, buggies, and wagons.  Installed at an intersection in London in 1868, it was a revolving lantern with red and green signals.  Red meant "stop" and green meant "caution."  The lantern, illuminated by gas, was turned by means of a lever at its base so that the appropriate light faced traffic.  On January 2, 1869, this crude traffic light exploded, injuring the policeman who was operating it.

Thomas Alva Edison invented the light bulb, the phonograph, automatic telegraph, motograph, paraffin paper(which was used to wrap candy), electric pen, carbon rheostat, microtasimeter, sockets, switches, insulating tape, gummed paper tape, magnetic ore separator, life-sized electric railway, motion picture camera, steel alkaline storage battery, and many other things.  He had 1,368 different patents.

The Invention of the Light Bulb: Davy, Swan and Edison\n\nThe first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc. \nMuch later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England. \n\nIn 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people. \n\nThe inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.

This is the second dumb question you've asked tonight.  Stop it.  You know exactly who invented the moon walk.  Are you trying to be funny?

The invention of the laser, which stands for light amplification by stimulated emission of radiation, can be dated to 1958 with the publication of the scientific paper, Infrared and Optical Masers, by Arthur L. Schawlow, then a Bell Labs researcher, and Charles H. Townes, a consultant to Bell Labs. That paper, published in Physical Review, the journal of the American Physical Society

Nobody invented electricity - it is a naturally occuring phenomenon (for example - lightning) that has been around as long as Earth. Benjamin Franklin is often credited with discovering the properties of electricity (although this is probably a myth), and Thomas Edison invented the electric light.

Johann Wolfgang!\n\nHe discovered furfural, worked on the use of platinum as a catalyst, and invented a lighter, known as Döbereiner's Lamp.\n\n:)

Just so you know, the traffic light times vary from intersection to intersection in most cities.  They vary by the size of the intersection, the amount of traffic normally expected, and the time of day.  \n\nSome modern traffic lights do not even have assigned times.  Sensors placed in the street determine when traffic is waiting and the light system adapts.

Could it be that he invented the lightbulb? And a bunch of other stuff as well.

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,097 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.\n\nIn 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.

It's not the city as a whole, just a few idiots! If there is such a thing as Karma, they'll someday get back what they have given out. They should make the lights longer.\n\n\nI love your suggestion about the parade. Awesome idea!!

Edison did not invent the electric lightbulb, which was pioneered by Heinrich Goebel in 1854. Goebel's lamps lasted up to 400 hours, but he did not patent them. Other light bulbs were created by James Woodward and Matthew Evans (patented in 1875) and equipped with carbon filament by Joseph Swan in 1878. However,it was Edison's relentless and endless experimentation that made the lightbulb a practical, commercial proposition. He purchased the 1875 patent and had a team of developers try many alternative materials and thus was eventually able to prolong the burning time in 1879.\nOn November 21, 1877 and he demonstrated the device for the first time on November 29 (he patented it on February 19, 1878).  , Edison invented the phonograph.\nEdison patented the Kinetoscope on August 31, 1887.
