Do you know . . .Ancient cultures measured time effectively with water clocks? An engineer within the first century B.C. designed an odometer to calculate distance traveled? humans computed the 1st values of pi approximately 4 thousand years in the past? Computing know-how is as outdated as human society itself. the 1st people on the earth used uncomplicated computing talents. They counted by means of carving tally marks in bone. They used physique elements and simple instruments to degree. Over the centuries, historic peoples realized extra approximately computing. humans within the old heart East used scales to degree items for buying and selling. the traditional Egyptians wrote textbooks together with multiplication and department difficulties. the traditional chinese language constructed an abacus for fast calculations. historic Greeks made advances in geometry. What forms of instruments and methods did historic mathematicians use? Which in their innovations and discoveries have stood the try out of time? and the way did the ancients set the degree for our personal sleek computing? examine extra in historic Computing expertise.
