81、Charles Babbage:Father of the Computer
Charles Babbage was born too soon.He hoped to invent a calculator.But the technology of his time was too simple.Babbage could not make his dream come true.
All his life,Baggage was interested in (81)numbers.For example,he could find out how (82)fast a pig's heart beats or make a table to calculate how much wood a man could saw(锯) in 10 hours.
Baggage was also an inventor.Around 1830,he decided to (83)designed and build a machine for doing simple mathematical calculations.He called this machine the Difference Engine.
Making the machine
The Difference Machine was very big and difficult to make.It was made of two tons of steel and gears(齿轮).While he was building this (84)heavy machine,he had an idea for a new machine.This one would do all kinds of calculations.He called it the Analytical Engine.It was the start of the modern computer.But Babbage used up all his money (85)before he could complete either machine.
Re-inventing the Engine
In 1854,two Swedish inventors built a working mechanical calculator.It was (86)based on the Difference Engine.This machine was able to print out different kinds of forms and tables.It was very accurate.
Babbage was the first person to come up with the idea of computers.And he is more famous today than he (87)was in his day.
