Study Notes
Early Mathematical Practices
- Pre-dynastic Egyptians and Sumerians exhibited geometric designs on artifacts by the 5th millennium BCE.
- Megalithic societies in northern Europe also showcased geometric patterns around the 3rd millennium BCE.
- Mathematics emerged in response to bureaucratic needs, primarily for land measurement and taxation in settled agricultural civilizations.
Sumerian/Babylonian Contributions
- Sumer, located in modern-day Iraq, is known as the "cradle of civilization" for its innovations such as writing, the wheel, and agriculture.
- The Sumerians created the earliest known writing system, a pictographic script inscribed as cuneiform on clay tablets.
- A numerical representation system: small clay cone for one, clay ball for ten, and large cone for sixty, dates back to the 4th millennium BCE.
- A precursor to the abacus was in use from 2700-2300 BCE in Sumer.
Sumerian/Babylonian Number System
- The sexagesimal (base 60) numeric system was developed, utilizing finger and knuckle counting.
- Babylonian numbers utilized a true place-value system, similar to modern decimal systems but based on 60.
- The number 60 is significant due to its numerous divisors, facilitating early calculations and modern time measurements (60 seconds, 60 minutes, 360 degrees).
- The concept of zero as a placeholder was introduced by the Babylonians, differentiating it from modern uses of zero.
Advanced Mathematical Concepts
- Babylonian mathematics included various topics such as fractions, algebra, and solving linear and quadratic equations.
- Notable achievements of Babylonian tablets (1800-1600 BCE) included approximations for √2 accurate to five decimal places, knowledge of perfect reciprocal pairs, and square/cubic number lists.
- An estimate of π (3.125) was also recorded, reflecting advanced understanding.
Geometry and Architectural Applications
- Babylonians applied geometric principles in architecture and recreational activities like gaming.
- They calculated areas of rectangles, triangles, and trapezoids, as well as the volumes of bricks and cylinders.
- The Plimpton 322 clay tablet, dating to around 1800 BCE, suggests advanced knowledge of Pythagorean triangles, listing 15 perfect right triangles with whole number sides.
