14 june 2019June 14: Day in the history of science and technology
On June 14, 1822, English mathematician Charles Babbage sent a letter to the British Royal Astronomical Society describing his famous difference machine - in fact, the world's first computer. On June 14, 1952, the customer earned the first UNIVAC I commercial computer in the United States and the third largest in the world. The customer was the United States Air Force, and the computer was installed at the Pentagon. Interestingly, it was the second copy purchased - the first one a year earlier was acquired by the census bureau, but it was eventually launched six months later.
