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.
The Danish physicist Valdemar Poulsen creates the world's first magnetic recording and reproduction, using a 1 mm thick steel wire as a magnetizable carrier. Nikola Tesla publicly demonstrated the first wireless remote control of a model ship. 1899: The dog "Nipper" is used in "His Master's Voice", the trademark for gramophones and records.
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.
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.
Silicon Image Inc. was an American fabless semiconductor company based in Hillsboro, Oregon, and active from 1995 to 2015. The company designed circuits for mobile phones , consumer electronics and personal computers (PCs).
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 first planar monolithic integrated circuit (IC) chip was demonstrated in 1960. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic ...
