In 1823 for the first time Jacob Berzelius discovered silicon tetrachloride (SiCl 4). [27] ... it accounts for 80% of the world's use of free silicon.
According to YouTube, this was the first worldwide free online broadcast of a major sporting event. [ 96 ] On March 31, 2010, YouTube launched a new design with the aim of simplifying the interface and increasing the time users spend on the site.
Berzelius is credited with discovering the chemical elements cerium and selenium and with being the first to isolate silicon, thorium, titanium and zirconium. Berzelius discovered cerium in 1803 [29] and selenium in 1817. [30] Berzelius also discovered how to isolate silicon in 1824, [31] and thorium in 1824.
Berzelius' experiences with glass-blowing had an additional bonus, in 1824 he discovered that one of the constituents of glass was a new element – silicon. Having already discovered three other elements prior to silicon: thorium, cerium and selenium, Berzelius spent the next ten years obsessively measuring more than two thousand chemical ...
The first commercially produced television receiver of the Daven Corporation in Newark is offered for $75. John Logie Baird transmits the first television pictures internationally, and the same across the Atlantic from London to New York. He also demonstrated the world's first color television transmission in London. 1929
The MITS Altair, the first commercially successful microprocessor kit, was featured on the cover of Popular Electronics magazine in January 1975. It was the world's first mass-produced personal computer kit, as well as the first computer to use an Intel 8080 processor. It was a commercial success with 10,000 Altairs being shipped.
The MOSFET was invented at Bell Labs between 1955 and 1960, after Frosch and Derick discovered surface passivation by silicon dioxide and used their finding to create the first planar transistors, the first in which drain and source were adjacent at the same surface.
2019: The first image of a black hole is captured, using eight different telescopes taking simultaneous pictures, timed with extremely precise atomic clocks. [1] 2020: NASA and SOFIA (Stratospheric Observatory for Infrared Astronomy) discover about 12 US fl oz (350 ml) of surface water in one of the Moon's largest visible craters.
