Charles Babbage invented _____________.
Charles Babbage invented _____________.
The correct option is B Difference engine
Charles Babbage invented
Difference engine.
A difference engine
created by Charles Babbage is an automatic mechanical calculator designed to
tabulate polynomial functions. Its name is derived from the method of divided
differences, a way to interpolate or tabulate functions by using a small set of
polynomial coefficients. Most mathematical functions commonly used by
engineers, scientists and navigators, including logarithmic and trigonometric
functions, can be approximated by polynomials, so a difference engine can
compute many useful tables of numbers.
Charles Babbage began to
construct a small difference engine in c. 1819 and had completed it by 1822
(Difference Engine 0). He announced his invention on June 14, 1822, in a paper
to the Royal Astronomical Society, entitled "Note on the application of
machinery to the computation of astronomical and mathematical tables".
This machine used the decimal number system and was powered by cranking a
handle. The British government was interested, since producing tables was
time-consuming and expensive and they hoped the difference engine would make
the task more economical.
