  George,you also check on google he has 7 patient rights on Fiber Optic,
  and the computer works on Fighter Jet F22 was done by him.
  If you don't know ask.

  Fibre optics has been in existence since the late 1700s. Read what I have searched for here:
  
  
  In the 1790s, the French Chappe brothers invented the first "optical telegraph" yet it used a free air and not glass.
  In the 1840s, physicists Daniel Collodon and Jacques Babinet showed that light could be bent, but they used water not glass.
  In 1880 Alexander Graham Bell patented an optical telephone system called the photophone.
  Also in 1880 William Wheeler invented a system of light pipes to direct light around the home.
  In 1888 in Vienna,Doctors Roth and Reuss, of used bent glass rods to illuminate body cavities.
  
  In 1930 German Heinrich Lamm was the first person to transmit an image through a bundle of optical fibers.
  
  When did George invent fibre optic?
  
  I did my MSc in Electronics as far back as 1978 and at that time there war fibre optics.
  
  What he may have done: he applied fibre optics in some project, but to say that he had invented it means you knoe nothing.
  
  How can one re-invent the wheel?

  "...He also invited all emerging countries to fully participate in educating the next generation experts, since they are the future, with the shift in innovation to software and app development which does not require expensive engineering laboratories, he appealed to educators to involve students early in computer coding and partner with other organizations, like the Hour of Code, to bring computer science to their classrooms..."

  Among some of the highlight of the competition was one of the teams’ presentation of a software app that allows videos to be transmit using basic cell phones and SMS for linking the user to a doctor. Another team developed a robotic car that can be remotely controlled using the cellphone.
  Dr. Thomas Mensah announced the top 3 winners of the competition, with Fernando Hernandez, Ray Lewis Vice Chairman and Reggie Howard President of the United Athletes Foundation and the Judges presented the teams with prices totaling $70,000 donated by Microsoft Corporation. The Invited panel of judges includes Ron Busby, President US Black Chamber of Commerce, Eliza Hernandez Executive Director US Hispanic chamber of Commerce, Avis Yates Rivers, President of Technology Concepts, and one of Managers of Software Development at Microsoft.

  By Mary Bellis
  In 1854, John Tyndall demonstrated to the Royal Society that light could be conducted through a curved stream of water, proving that a light signal could be bent.
  
  In 1880, Alexander Graham Bell invented his 'Photophone', which transmitted a voice signal on a beam of light. Bell focused sunlight with a mirror and then talked into a mechanism that vibrated the mirror. At the receiving end, a detector picked up the vibrating beam and decoded it back into a voice the same way a phone did with electrical signals. Many things -- a cloudy day for instance -- could interfere with the Photophone, causing Bell to stop any further research with this invention.
  
  In 1880, William Wheeler invented a system of light pipes lined with a highly reflective coating that illuminated homes by using light from an electric arc lamp placed in the basement and directing the light around the home with the pipes.
  
  In 1888, the medical team of Roth and Reuss of Vienna used bent glass rods to illuminate body cavities.
  
  In 1895, French engineer Henry Saint-Rene designed a system of bent glass rods for guiding light images in an attempt at early television.
  
  In 1898, American David Smith applied for a patent on a bent glass rod device to be used as a surgical lamp.
  
  In the 1920's, Englishman John Logie Baird and American Clarence W. Hansell patented the idea of using arrays of transparent rods to transmit images for television and facsimiles respectively.
  
  
  
  
  Fiber optics is the contained transmission of light through long fiber rods of either glass or plastics. The light travels by a process of internal reflection. The core medium of the rod or cable is more reflective than the material surrounding the core. That causes the light to keep being reflected back into the core where it can continue to travel down the fiber. Fiber optic cables are used for transmitting voice, images and other data at close to the speed of light.
  
  
  In 1930, German medical student, Heinrich Lamm was the first person to assemble a bundle of optical fibers to carry an image. Lamm's goal was to look inside inaccessible parts of the body. During his experiments, he reported transmitting the image of a light bulb. The image was of poor quality, however. His effort to file a patent was denied because of Hansell's British patent.
  
  n 1954, Dutch scientist Abraham Van Heel and British scientist Harold. H. Hopkins separately wrote papers on imaging bundles. Hopkins reported on imaging bundles of unclad fibers while Van Heel reported on simple bundles of clad fibers. He covered a bare fiber with a transparent cladding of a lower refractive index. This protected the fiber reflection surface from outside distortion and greatly reduced interference between fibers. At the time, the greatest obstacle to a viable use of fiber optics was in achieving the lowest signal (light) loss.
  
  In 1961, Elias Snitzer of American Optical published a theoretical description of single mode fibers, a fiber with a core so small it could carry light with only one wave-guide mode. Snitzer's idea was okay for a medical instrument looking inside the human, but the fiber had a light loss of one decibel per meter. Communications devices needed to operate over much longer distances and required a light loss of no more than 10 or 20 decibels (measurement of light) per kilometer.
  
  In 1964, a critical (and theoretical) specification was identified by Dr. C.K. Kao for long-range communication devices, the 10 or 20 decibels of light loss per kilometer standard. Kao also illustrated the need for a purer form of glass to help reduce light loss.
  
  In 1970, one team of researchers began experimenting with fused silica, a material capable of extreme purity with a high melting point and a low refractive index. Corning Glass researchers Robert Maurer, Donald Keck and Peter Schultz invented fiber optic wire or "Optical Waveguide Fibers" (patent #3,711,262) capable of carrying 65,000 times more information than copper wire, through which information carried by a pattern of light waves could be decoded at a destination even a thousand miles away. The team had solved the problems presented by Dr. Kao.
  
  In 1975, the United States Government decided to link the computers in the NORAD headquarters at Cheyenne Mountain using fiber optics to reduce interference.
  
  In 1977, the first optical telephone communication system was installed about 1.5 miles under downtown Chicago, and each optical fiber carried the equivalent of 672 voice channels.
  
  Today more than 80 percent of the world's long-distance traffic is carried over optical fiber cables, 25 million kilometers of the cable Maurer, Keck and Schultz designed has been installed world wide.
