Introduction  
This web site will discuss the famous Towers of Hanoi puzzle.
We will show its solution, count the number of moves it takes,
introduce recursion, powers of two, induction proofs, and other exciting
and useful mathematical concepts.

Legend has it that there is a temple near Hanoi, which is in Vietnam. In this temple there are monks who are solving a giant puzzle consisting of 64 golden rings of different sizes on three diamond needles. To solve the puzzle they must move the entire tower of 64 rings from the starting needle to the ending one. But they can move only one ring at a time, and they may never place a larger ring on top of a smaller one. The legend claims that once the monks are finished, the world will end. So we need to figure out how long it is going to take the monks to finish the puzzle.
 
Well, actually ...  
this puzzle was invented in 1883 by a
French mathematician called Edouard Lucas.

When the puzzle pictured there is finished this site will end,
and that's not a legend.
