Study Notes
Introduction to Computing
- Technological advancements, including computers, mobile devices, and the Internet, have significantly impacted society and improved living standards.
- Computing involves using computers for managing, processing, and communicating essential information in modern industrial technology.
Early Civilizations
- Contributions from early civilizations form the foundation of contemporary computing.
- Practical problems addressed by Egyptian mathematics included measuring time, floods, calculating land areas, bookkeeping, and tax calculations.
Egyptians
- Utilized a base 10 numerical system comprising distinct symbols for units ranging from one to one hundred thousand.
- The Rhind Papyrus served as a vital writing surface for documenting arithmetic and geometric problems, facilitating participation in projects like the Pharaoh’s building program.
Babylonians
- Thrived in Mesopotamia (Iraq) approximately from 2000 BC to 500 BC.
- Mathematical texts on clay cuneiform tablets included tables for arithmetic operations, cubes, and square roots.
- Employed a numerical system with only two symbols (1 and 10), combining them to form other numbers.
- Counting boards, utilized for aiding calculations, resembled an abacus and had grooves for placing beads.
Greeks
- Made significant contributions to mathematics around 500-600 BC, particularly in geometry through figures like Pythagoras and Thales.
- Pythagoras, influenced by Egyptian mathematics, established a secret society and is credited with foundational concepts, including the Pythagorean theorem.
- Thales contributed to Euclidean geometry, with his theorem relating to points on a circle defined by a diameter.
