A Brief History of the Jigsaw Puzzle
Puzzling has been around since the dawn of time (almost). Greek mathematician Archimedes puzzled around 250 B.C. to solve geometry problems. He cut a square into 14 pieces, and then examined how many different configurations could be made from those 14 pieces. This puzzle was recently solved by Bill Cutler, a mathematician from Cornell University, who showed the puzzle has 536 truly distinct solutions.
