The slow days are the worst around here, which is strange when you…. We buried my brother with his dreams. On colored scraps of paper my young son, Teddy, and I scrawled all…. Confusion and chaos lifted.

The whole point of a computer is to perform mathematical computations. In the year Jacquard Loom devised a punch card system with a power loom and an automatic card reader. In , Gottfried Wilhelm von Leibniz invented a computer that was built in ; it could add and, by successive adding and shifting, multiply. Leibniz invented a special "stepped gear" mechanism for introducing the addend digits, and this mechanism is still in use. The prototypes built by Leibniz and Pascal were not widely used but remained curiosities until more than a century later, when Tomas of Colmar Charles Xavier Thomas developed the first commercially successful mechanical calculator that could add, subtract, multiply, and divide. A succession of improved "desk-top" mechanical calculators by various inventors followed, so that by about the available built-in operations included accumulation of partial results, storage and reintroduction of past results, and printing of results, each requiring manual initiation. These improvements were made primarily to suit commercial users, with little attention given to the needs of science.
The history of the modern computer keyboard begins with a direct inheritance from the invention of the typewriter. It was Christopher Latham Sholes who, in , patented the first practical modern typewriter. Soon after, in , the Remington Company began mass marketing the first typewriters. After a series of technological developments, the typewriter gradually evolved into the standard computer keyboard your fingers know so well today.
Later on it was used to make calculation for nuclear weapons research, weather predictions, and wind tunnel design. Mauchly and American Electrical. History of Computers One could say that the history of the computer started with the abacus, a wooden frame holding two wires with beads strung on them.
