pendulum. pendulum, a mass, called a bob, suspended from a fixed point so that it can swing in an arc determined by its momentum and the force of gravity. The length of a pendulum is the distance from the point of suspension to the center of gravity of the bob (see center of mass). Share | Cite. where T is the period, or time for one complete swing, l is the length, g is the acceleration of gravity (see gravitation), and Ï = 3.14ââ¦ (see harmonic motion). In 1673, Huygens devised a practicable means of making a pendulum control the speed with which a clock mechanism runs.
We could argue that the first computer was the abacus or its descendant, the slide rule, invented by William Oughtred in 1622. But the first computer resembling today's modern machines was the Analytical Engine, a device conceived and designed by British mathematician Charles Babbage between 1833 and 1871.
Inventors of the Modern Computer. The First Freely Programmable Computer invented by Konrad Zuse. By Mary Bellis. In 1941, the Z3 contained almost all of the features of a modern computer as defined by John von Neumann and his colleagues in 1946.The only exception was the ability to store the program in the memory together with the data.aper was in short supply in Germany during the war. According to The Life and Work of Konrad Zuse (by Horst Zuse). The block structure of the Z3 is very similar to a modern computer.
