The castle clock, a hydropowered mechanical astronomical clock invented by Ismail al-Jazari in 1206, was the first programmable analog computer.
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.
Numbers could also be represented in the form of digits, automatically manipulated by a mechanical mechanism.
Although this approach generally required more complex mechanisms, it greatly increased the precision of results.
In 1804, Joseph-Marie Jacquard developed a loom in which the pattern being woven was controlled by a paper tape constructed from punched cards.
The paper tape could be changed without changing the mechanical design of the loom.While producing the first logarithmic tables, Napier needed to perform many tedious multiplications.It was at this point that he designed his 'Napier's bones', an abacus-like device that greatly simplified calculations that involved multiplication and division.AD 1000); the equatorium and universal latitude-independent astrolabe by Abū Ishāq Ibrāhīm al-Zarqālī (c.AD 1015); the astronomical analog computers of other medieval Muslim astronomers and engineers; and the astronomical clock tower of Su Song (1094) during the Song dynasty.It utilised a stepped drum similar in conception to that invented by Leibniz.Mechanical calculators remained in use until the 1970s.He followed this up with the modern slide rule in 1632, essentially a combination of two Gunter rules, held together with the hands.Slide rules were used by generations of engineers and other mathematically involved professional workers, until the invention of the pocket calculator.The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers.Before the 20th century, most calculations were done by humans.
