Newton's Principia

1687 C.E.

Ahlfors and Douglas awarded the Fields Medals

1936 C.E.

It was proposed in 1924 that gold medals should be awarded to recognize outstanding achievement. It wasn't until 1936 that the medals were first awarded to Ahlfors and Douglass. The Fields Medal is equivalent to the Nobel Prize.

Four Color conjecture verified by computer

1976 C.E.

Ken Appel and Wolfang Haken showed the four color conjecture was true using 1200 hours of computer time to examine 1500 configurations. The theorem states that any map in a plane can be colored using four colors in such a way that regions sharing a common boundary (other than a single point) do not share he same color
