Ars Magna (The Great Art) published in 1545 by Girolamo Cardano, included techniques for solving cubic (to the third power) and quartic (to the fourth power) equations. The solution for cubic equations was developed by Scipione del Ferro, then passed on to a student who provoked Niccolo Fontana (aka Tartaglia) to also develop the solution. […]

Paolo Ruffini was born in Italy in 1765 and was a mathematician. After the cubic equation was solved in 1539 by del Ferro, Tartaglia and Cardano, and Ferrari had solved the quartic equation by 1545, mathematicians turned their attention toward attempting to solve the quintic. The previous polynomial equations (quadratic, cubic and quartic) had all […]

Born in Erlangen, Bavaria, Germany in 1882, Emmy Noether was a mathematician who laid the groundwork for the idea of symmetry in mathematics and physics. She studied the works of Hilbert, Klein and Minkowski and was peer with Hermann Weyl. Noether’s theorem – in 1915, she proved a relationship between symmetries in physics and conservations […]

Evariste Galois was born in Bourge-la-Reine, France in 1811. His major contribution is known as Galois Theory, which he discovered while trying to find roots for polynomial equations. He was studying permutations of roots and realized that symmetries found in the roots can explain their solvability. This laid the foundation for what is now known […]
