Read the text about an English mathematician and ask special questions about the gaps. Then fill in the gaps with information pieces from the box below.

Babbage

While Thomas of Colmar was developing the desktop calculator, 1)__________was started in Cambridge, England, by Charles Babbage (of which the computer store «Babbages», now GameStop, is named), a mathematics professor. In 2) ____, Babbage realized that many long calculations, especially those needed to make mathematical tables, were really a series of predictable actions that were constantly repeated. From this 3)__________ suspected that it should be possible to do these automatically.

He began to design an automatic mechanical calculating machine, which he called a difference engine. By 1822, he had 4)__________. With financial help from the British government, Babbage started 5)__________ in 1823. It was intended to be steam powered and fully automatic, including the printing of the resulting tables, and commanded by a fixed instruction program. The difference engine, although having limited adaptability and applicability, was really a great advance. Babbage continued to work on it for 6) __________ years, but in 1833 he lost interest because he thought he had a better idea – 7)__________. Babbage called this idea 8)__________. The ideas of this design showed a lot of foresight, although this couldn’t be appreciated until a full century later. The plans for this engine required an identical decimal computer operating on numbers of 50 decimal digits (or words) and having a storage capacity (memory) of 9)__________. The built-in operations were supposed to include everything that a modern general – purpose computer would need, even the all important Conditional Control Transfer Capability that would allow commands to be executed in any order, not just the order in which they were programmed. The analytical engine was soon to use punched cards (similar to those used in a Jacquard loom), which would be read into the machine from several different Reading Stations. The machine was supposed to operate automatically, by steam power, and require only one person there. Babbage’s computers were never finished. Various reasons are used for his failure. Most used is 10)________. Another speculation is that Babbage was working on a solution of a problem that few people in 1840 really needed to solve. After Babbage, there was a temporary loss of interest in automatic digital computers. Between 1850 and 1900 great advances were made in 11)__________, and it came to be known that most observable dynamic phenomena can be identified by differential equations(which meant that most events occurring in nature can be measured or described in one equation or another), so that easy means for their calculation would be helpful. Moreover, from a practical view, the availability of steam power caused manufacturing (boilers), transportation (steam engines and boats), and commerce to prosper and led to 12)__________. The designing of railroads, and the making of steamships, textile mills, and bridges required 13________.

Even the assessment of the power output of a steam engine needed 14)___________. A strong need thus developed for a machine that could rapidly perform many repetitive calculations.
