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.
