Babbage fervently believed that science could be applied to the improvement of social conditions. Both Britain and Europe were still ruled largely for the benefit of the wealthy landowning class. Babbage’s friends in Europe were active in changing that, to give ordinary working people a larger role in their own government. 53 Charles Babbage Their views fitted well with his own liberal attitudes regarding conditions back home.

The physical engine would have measured eight feet high, seven feet wide, and three feet deep. CHAPTER 3 Inventing the Difference Engine When Charles Babbage and John Herschel visited Paris in 1819, they inspected a great mathematical work.

Many of the annotations are in Babbage’s handwriting and give clues about the contribution made by his engineer, Joseph Clement, to the design process. 38 Image Not Available Inventing the Difference Engine DIFFERENCES IN SEQUENCES OF NUMBERS o make Babbage’s Difference Engine work, the operator has to specify the initial differences to be entered into the machine. For automatic operation, the difference applied to the starting wheel has to be a constant. As you can see in the following tables, in a sequence of the squares of integers, the second difference is constant at 2; in a sequence of cubes the third difference (6) is constant.
