Study Notes

The Egyptians

  • Developed mathematical practices to address practical problems like time measurement, flood tracking, land area calculation, bookkeeping, and tax computation.
  • Utilized a base 10 numerical system, featuring distinct symbols for values like one, ten, a hundred, a thousand, ten thousand, and a hundred thousand.
  • The Rhind Papyrus serves as a significant artifact, containing comprehensive arithmetic and geometric problems, aiding education for projects like the Pharaoh's building initiatives.

The Babylonians

  • Flourished in Mesopotamia (modern-day Iraq) from around 2000 BC to 500 BC.
  • Mathematical texts were inscribed on clay tablets using cuneiform script, deciphered in the 19th century, showcasing various mathematical operations including basic arithmetic, cubes, and square roots.
  • Employed a binary symbol system consisting of just 1 and 10, combining these symbols to represent larger numbers.
  • Introduced counting boards to facilitate simple calculations, similar to the abacus, which likely preceded them.

The Greeks

  • Significant contributions to mathematics emerged from figures like Pythagoras and Thales around 500-600 BC, focusing on geometry.
  • Pythagoras, having studied in Egypt, is recognized as a philosopher and mathematician, credited with the Pythagorean theorem and the establishment of a secret society (the Pythagoreans) that believed in the spiritual significance of numbers.
  • Thales made notable contributions to Euclidean geometry, with Thales' theorem establishing fundamental relationships between points on a circle and the diameter.
