Study Notes
Early Numerical Awareness
- Prehistoric ancestors instinctively distinguished between quantities, knowing the difference between one and two antelopes.
- Transition from concrete counting to abstract numerical concepts, like the word "two," took a significant amount of time.
Language and Numbers Among Hunter-Gatherers
- Isolated Amazonian tribes have limited vocabulary for numbers, often only having terms for "one," "two," and "many."
- Some tribes only count up to five, reflecting minimal need for formal numerical systems due to lack of settled agriculture or trade.
Early Evidence of Counting
- Notched bones found in Africa, dating back 35,000 to 20,000 years, indicate early counting methods rather than formal mathematics.
- Markings represent basic tallying rather than advanced numerical concepts.
Geometric Representations
- Pre-dynastic Egyptians and Sumerians showcased geometric designs on artefacts during the 5th millennium BCE.
- Some megalithic societies in northern Europe also represented patterns and designs from the 3rd millennium BCE, primarily for art rather than systematic mathematics.
Rise of Mathematics with Civilization
- Mathematics developed primarily due to bureaucratic needs as civilizations established agriculture, particularly in Sumerian, Babylonian, and ancient Egyptian contexts.
- Requirements included land measurement and taxation, leading to more formal methods of calculation.
Evidence of Early Mathematical Practices
- Petroglyphs from Knowth and Newgrange burial mounds in Ireland (circa 3500 BCE and 3200 BCE) display basic arithmetic and geometric notations.
- Zig-zag glyphs used for counting influenced numerical systems in Britain and Ireland into the 1st millennium BCE.
Ancient Astronomical Practices
- Stonehenge, a Neolithic site from around 2300 BCE, demonstrates early understanding of measurements through its use of the numbers 60 and 360, likely developed independently from Sumerian sexagesimal systems.
