Study Notes
Prehistoric Mathematics Findings
- Earliest-known artificial eye discovered linked to an ancient priestess, highlighting prehistoric cultural complexity.
Sumerian and Babylonian Mathematics
- Sumerians created advanced civilizations with architecture, written language, and irrigation systems around 4000 BCE.
- Cuneiform writing predates Egyptian hieroglyphs, marking a significant development in human communication.
- The Mesopotamian region is commonly referred to as Babylonian, despite the city of Babylon not being the continual cultural center.
- Babylon fell to Persia in 538 BCE; however, its mathematical practices persisted into the Seleucid period and influenced Greek thinkers.
Greek Contributions to Mathematics
- Greek mathematics emerged around 1000 BCE; existing texts date from about 300 BCE, primarily through copies.
- Attic or Herodianic numerals were developed around 450 BCE, using a base 10 system with symbols for key values (1, 5, 10, 50, 100, 500, 1000).
- Greek Ionic numerals represented numbers through the alphabet, using additional marks to denote thousands.
Plato and Geometry
- Plato viewed mathematics as essential to philosophy and the pursuit of knowledge, emphasizing theoretical understanding over practical application.
- Solid geometry was crucial for studying astronomy, distinguishing between material and ideal geometric forms.
- Ideal bodies in astronomy represented perfect relationships, while harmonic studies focused on abstract numerical relationships rather than tangible sounds.
Platonic Solids
- Plato identified five regular solids: tetrahedron (fire), octahedron (air), icosahedron (water), cube (earth), dodecahedron (cosmic structure).
- These shapes reflect Plato’s belief in their fundamental role in the universe’s structure, combining aesthetics and mathematics.
Mathematical Inquiry
- Greek thinkers shifted focus from accepted norms to rational inquiry, forming the basis for mathematical proofs, which are foundational to modern mathematics.
- The study of mathematics, particularly through Plato's philosophy, aimed at understanding the essence of truth and abstract concepts beyond empirical observation.
