Quirky Science
S01E10 Computers: Early examples of computers are the ancient Antikythera machine and the 19th century engines made by Charles Babbage. But Babbages's designs could not be completed as its construction was ahead of its time! The makers of the first electric computer got a $850 fee to complete their work. They did, but WW2 halted progression. That same war sparked the need for a rapid development for strong calculation machines. The computer was invented because astronauts and the military needed huge calculators. You see, it's hard for a human being to calculate immense figures like "how far will this space shuttle be in six days if we launch it today?" These early computers were 27,000 kg examples yet had about as much power as a calculator today. One invention created the possibility to downsize these huge computer models: the transistor. Developed in the early 1950s the fingertip - sized transistors replaced huge vacuum tubes of the pre-war computers, in helping them to make...

E09 The Internet was invented during the cold war and launched in 1969. Yet it wasn't made for the public. In fact, it was developed for the army to communicate quickly and secretly so that no spies could intercept and no bombs could disrupt the sharing of information! It was nothing like we know today. The Internet involved computers exchanging text, on a black field with green letters, and e-mail was only invented 2 years later because the developers needed a reliable tool to communicate. So only in 1972 was this application; electronic mail, introduced. The Internet we know now was actually a second, separate invention, launched over a decade and a half after the Internet was first launched, and was called the 'World Wide Web'. Nobody was paying attention to Tim Berners-Lee and his pet idea, even though he had a radical new way for scientists to share data by linking documents to one another over the Internet! His proposal came back with the words "vague but exciting" written...
