The first known report on the light emitted by a solid diode was made in 1907 by the British experiment, Henry Joseph Raund.
For the first time, the Russian physics of Oleg Vladimirovich Losev was targeted. The detected L.A. candle is yellow, green and orange-coloured with the name of electrominescence or Losev Light.
In 1923, Losev receives the first working señola called " light relay " . And only in 1962, at the University of Illinois, a group led by Nick Holonag received a señode as we present it today. If the Soviet scholars had taken great attention to the inventions of Losev, if not the Great Patriotic War, in which there had been no more seculars, no doubt the silicon semiconductor technologies that had become key to technology would now be in the hands of Russian scientists.
3D films (stereophillms)
The three-dimensional image will no longer surprise anyone, it's normal today.
It is accepted that the date of birth of the filmmaker is well known, 1895.

Less is aware that the inventor, Joseph Andreievich Timchenko, a mechanic of the University of Odes, created a cinema of his own design two years earlier, another 1893. On 9 January, 1894, at the sixth meeting of the physics section of the Fifth Congress of Russian environmentalists and doctors in Moscow, I. Timchenko was first presented to the public, the magnificent viewers saw the rolling cavalry and methane of the Copy on the screen. Two days later, on 11 January 1894, a record of this was published, without exaggeration, a historic meeting recording the very fact and date of the public demonstration of the first film in history...

Fredrick Eugene Eve patented a stereotype plant in 1900. His camera was equipped with two objects at a distance of 1, 75 inch (~4, 44 cm)
