Date | Event | c. 2400 BC | The abacus - the first known calculator‚ was probably invented by the Babylonians as an aid to simple arithmetic around this time period. This laid the foundations for positional notation and later computing developments. | 1300 | Ramon Llull invented the Lullian Circle: a notional machine for calculating answers to philosophical questions (in this case‚ to do with Christianity) via logical combinatorics. This idea was taken up by Leibniz centuries later‚ and is thus

EDVAC Project origin and plan ENIAC inventors John Mauchly and J. Presper Eckert proposed the EDVAC’s construction in August 1944‚ and design work for the EDVAC commenced before the ENIAC was fully operational. The design would implement a number of important architectural and logical improvements conceived during the ENIAC’s construction and would incorporate a high speed serial access memory.[1] Like the ENIAC‚ the EDVAC was built for the U.S. Army’s Ballistics Research Laboratory at the Aberdeen

Etymology The first recorded use of the word “computer” was in 1613 in a book called “The yong mans gleanings” by English writer Richard Braithwait I haue read the truest computer of Times‚ and the best Arithmetician that euer breathed‚ and he reduceth thy dayes into a short number. It referred to a person who carried out calculations‚ or computations‚ and the word continued with the same meaning until the middle of the 20th century. From the end of the 19th century the word began to take on its

Computer Hardware came about when machines needed separate manual actions to be able to perform specific mathematical functions. Luckily in 1941‚ a man by the name of Konrad Zuse invented what was considered the first working‚ fully operable computer. Prior to this‚ most of the calculations were done manually to calculate by people with adding machines. Today these adding machines are better known as calculators. Back then‚ all you had to do is push buttons‚ but in today’s modern software technology

What does it mean to be German? an essay by Max Zöfeld This is a hard question‚ which may sound a bid jingoistic in the wrong ears. A blonde person with blue eyes‚ well organised and every time punctual is that kind of person‚ which comes to the mind of many people in other countries when they here the word “German”‚ but the question is why? Maybe they are influenced by the Aryan standards which became known in the time of the national socialists. However my own opinion distinguishes from this

The History of Computers There are many major milestones in the history of computers‚ starting with 1936‚ when Konrad Zuse built the first freely programmable computer.

exception of Babbage’s punch card machine in 1832 (it was never finished). 1910 marked one of the most important times in the history of the computer with the invention of the first electrical automatic computing machine‚ the Z1‚ designed by Konrad Zuse in Germany. Finally after three hundred years there was an advance worth writing home about‚ but the German government had no time for such things as WW1 began to rage through Europe‚ so sadly Zuse’s machine was also never completed.
