Question 1

Accepted Answer

A) True 
 B)False  False

Question 2

Explain the achievement of the Difference Engine of Charles Babbage, and explain the challenge he confronted in trying to construct the larger model.

Accepted Answer

In 1823, Babbage extended the ideas of Pascal and Leibniz and constructed a working model of the largest and most sophisticated mechanical calculator of its time. This machine, called the Difference Engine, could do addition, subtraction, multiplication, and division to 6 significant digits, and it could solve polynomial equations and other complex mathematical problems as well. Babbage tried to construct a larger model of the Difference Engine that would be capable of working to an accuracy of 20 significant digits, but after 12 years of work he had to give up his quest. The technology available in the 1820s and 1830s was not sufficiently advanced to manufacture cogs and gears to the precise tolerances his design required. Like Galileo's helicopter or Jules Verne's atomic submarine, Babbage's ideas were fundamentally sound but years ahead of their time. (In 1991, the London Museum of Science, using Babbage's original plans, built an actual working model of the Difference Engine. It worked exactly as Babbage had planned.)
