“If it’s just turning the crank, it’s algebra; but if there is an idea present then it’s topology.”

“It was my lot to plant the harpoon of algebraic topology into the body of the whale of algebraic geometry.”
- Solomon Lefschetz (In his famous 1924 monograph L ′analysis situs et la géométrie algébriques)
