释义
Babbage, Charles (1792–1871)

Mathematics
  • and inventor of mechanical calculators. His ‘analytical engine’ was designed to perform mathematical operations mechanically using a number of features essential in the design of today’s computers, but, partly through lack of funds, the project was not completed.


Statistics
  • He studied mathematics at Cambridge U where he was a co-founder of the ‘Analytical Society’ which advanced the cause of what is now the standard notation for differentiation. After graduation in 1814, he was elected FRS in 1816 and FRSE in 1820 (the year in which he was a co-founder of what is now the Royal Astronomical Society). He is known as the ‘Father of Computing’, having formulated the idea of a mechanical calculator during his student days. A first model was demonstrated in 1822, at which time he stated ‘I wish to God these calculations had been executed by steam’. A working model of his second machine is at the Science Museum in London. At the time of his death, however, the notion was almost forgotten. From 1828 to 1839 he was Lucasian Professor of Mathematics at Cambridge U. The initial decision to found the RSS was taken at Babbage’s house in 1834. A crater on the Moon is named after him.

Philosophy
  • Babbage has become famous posthumously because he foresaw many of the fundamentals of computing. He designed a ‘difference engine’ and an ‘analytical engine’ for the computation of mathematical tables, his machines working on a store (memory) according to a ‘mill’ or set of operations ‘programmed’ by punch cards. He also wrote a ninth Bridgewater treatise, challenging Hume on miracles.
