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.
Who invented the first computer is not a question with a simple answer. There have been a lot of major milestones throughout history that warrant mentioning. The adventure starts in the year 1936. 1936- Konrad Zuse invented the Z1 Computer. This was the first computer that was freely programmable.
