Were you aware . . .Ancient cultures measured time correctly 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 previous as human society itself. the 1st people on the earth used simple computing talents. They counted via carving tally marks in bone. They used physique elements and simple instruments to degree. Over the centuries, old peoples discovered extra approximately computing. humans within the old center 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 built an abacus for fast calculations. historic Greeks made advances in geometry. What sorts of instruments and methods did historical mathematicians use? Which in their innovations and discoveries have stood the try out of time? and the way did the ancients set the level for our personal smooth computing? research extra in historical Computing expertise.

To keep track of lucky days and holidays, the Maya needed an accurate calendar—one in step with the solar year. The Maya used two calendars. The Tzolkin, or sacred calendar, contained 260 days.

Aryabhata also introduced a way to find the length of a side of a cube with a known volume. We call this a cube root. ANCIENT INDIA 41 T he ancient Chinese were advanced mathematicians. They developed the basis for a decimal system and invented the first automated computing device, the abacus. They may have even discovered ideas of geometry before the Greeks made those ideas famous.
