Study Notes

Introduction to Computing and Ancient Contributions

  • Technological advancements such as computers, mobile devices, and the Internet have significantly improved society and living standards.
  • Computing involves activities that manage, process, and communicate vital information, essential in modern technology.

The Egyptians

  • Egyptian mathematics addressed practical problems like timekeeping, flood measurement, land area calculation, bookkeeping, and tax computation.
  • They employed a base 10 numerical system using distinct symbols for values ranging from one to a hundred thousand.
  • Notable artifact: Rhind Papyrus, a significant Egyptian document containing arithmetic and geometric problems, facilitated education and involvement in construction projects for the Pharaoh.

The Babylonians

  • Civilization thrived in Mesopotamia (modern-day Iraq) from around 2000 BC to 500 BC.
  • Mathematical texts were inscribed on clay cuneiform tablets, providing tables for basic arithmetic, cubes, and square roots.
  • Utilized a numerical system with only two symbols (1 and 10) that could be combined to represent other numbers.
  • Counting boards resembling an early form of the abacus were used for calculations, assisting in counting procedures.

The Greeks

  • Key figures: Pythagoras and Thales, who made notable contributions to geometry around 500-600 BC.
  • Pythagoras, influenced by Egyptian mathematics, founded a secret society (the Pythagoreans) that explored the philosophical significance of numbers and the transmigration of souls.
  • Celebrated for the Pythagorean theorem, although the Babylonians had knowledge of this concept centuries earlier.
  • Thales contributed to Euclidean geometry, formulating a theorem regarding points on a circle, establishing foundational principles in mathematics.
