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.
Steve Wozniak is an American computer scientist best known as one of the founders of Apple and the inventor of the Apple II computer. Synopsis Steve Wozniak was born in San Jose, California, on August 11, 1950. In partnership with his friend Steve Jobs, Wozniak invented the Apple I computer. The pair founded Apple Computers in 1976 with Ronald Wayne, releasing some of the first personal computers on the market. Wozniak also personally developed the next model, Apple II, which established Apple as a major player in microcomputing. Founding Apple Computer
