Study Notes

  • Mathematics explores quantity, structure, space, and change.
  • Mathematicians and philosophers hold varying views on the scope and definition of mathematics.
  • Mathematicians identify patterns and create new conjectures.
  • Mathematical proofs are used to validate or invalidate conjectures.
  • Mathematical research is essential for solving mathematical problems.
  • Mathematics plays a vital role in natural science, engineering, medicine, finance, and social science.
  • Applied mathematics has created entirely new mathematical disciplines.
  • Pure mathematics is pursued by mathematicians for its intrinsic value, without specific applications in mind.

  • The ancient Egyptians made advances in arithmetic, geometry, and surveying.
  • The ancient Egyptians used a decimal system.
  • Practical problems involving land area, volumes, and bread were solved by the ancient Egyptians.
  • The ancient Greeks initiated a methodical study of mathematics as a distinct subject, beginning around 600 BC.
  • Greek mathematics was built upon logical reasoning and proofs, particularly in geometry.
  • The axiomatic method, consisting of definitions, axioms, theorems, and proofs, was introduced by Euclid (c. 300 BC).
