- 1882-1935. German mathematician.
- Proved Noether’s theorem (1918): every continuous symmetry of a physical system corresponds to a conserved quantity.
- Symmetry in time yields conservation of energy; symmetry in space yields conservation of momentum.
- Founded modern abstract algebra: ring theory, ideal theory, and the axiomatic approach to algebraic structures.
- Noether’s theorem is the deepest link between physics, symmetry, and conservation laws.
- Her algebraic abstractions underpin modern cryptography, coding theory, and algebraic geometry used in zero-knowledge proofs.
- Albert Einstein called her the most important woman in the history of mathematics.
