Up: About the Towers puzzle.
The real situation is slightly more fantastic than I represented it. The pegs are of diamond, and the 64 disks are of gold.
Actually, this is all just legend. And it's not even an ancient legend: It was invented in 1883 by mathematician Edouard Lucas. He wanted to sell his 8-disk puzzle, and he created the name and the story to make the puzzle more intriguing.
