The History of Pi Throughout the history of mathematics‚ one of the most enduring challenges has been the calculation of the ratio between a circle’s circumference and diameter‚ which has come to be known by the Greek letter pi. From ancient Babylonia to the Middle Ages in Europe to the present day of supercomputers‚ mathematicians have been striving to calculate the mysterious number. They have searched for exact fractions‚ formulas‚ and‚ more recently‚ patterns in the long string of numbers

HISTORY OF COMPUTERS Ancient era Suanpan (the number represented on this abacus is 6‚302‚715‚408) Devices have been used to aid computation for thousands of years‚ mostly using one-to-one correspondence with fingers. The earliest counting device was probably a form of tally stick. Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres‚ cones‚ etc.) which represented counts of items‚ probably livestock or grains‚ sealed in hollow unbaked clay containers.[1][2]

Zero is a unique number that means “empty space” and that which represents a number and its use for computation. It was conceived from the Hindus from India. The earliest recorded evidence was found on the Gvalior inscription‚ however‚ the zero we are accustomed to today‚ came much later. Zero has two basic uses: to mean empty space or to represent a number used for computation. It is especially important in positional notations. Positional notations‚ is a numerical system in which each position

Atom History Essay An Atom is a basic unit of matter that consists of a dense‚ central nucleus surrounded by a cloud of negatively charged electrons. The Atom was theorized by a man named Democritus of Abdera‚ Thrace in between c.a 460 BC - ca. 370 B.C. Atom is derived from the Greek word “atomos” ‚ which means to be uncuttable. He had a theory that everything is composed of “atoms”‚ which he believed that these minuscule objects are indivisible‚ indestructible and have and always been in motion

HISTORY OF COMPUTER THE PRE-MECHANICAL AGE: 3000 B.C. – 1450 A.D. 1. Writing and Alphabets – Communication First development of signs corresponding to spoken sounds‚ instead of pictures‚ to express words. Around 2000 B.C.‚ Phoenicians created symbols that expressed single syllables and consonants (the first true alphabet) The Greeks later adopted the Phoenician alphabet and added vowels; the Romans gave the letters Latin names to create the alphabet we use today. 2.

Equations of Motion* When an object (with initial velocity u) moves in a straight line with constant acceleration a‚ its displacement s from its starting point‚ and its final velocity v‚ change with time t. Note that both v and u are instantaneous velocities. The following equations tell us how these quantities are related: v = final velocity u = initial velocity a = acceleration s= displacement (not distance) t = time Procedure for solving problems using equations of motion
