In principle, this impossible math allows for a glue-free bridge of stacked blocks that can stretch across the Grand Canyon—and into infinity Keep going. If you stack as many blocks as you can, what ...
The key to the classic problem uses the harmonic series of 1 + 1/ 2 + 1/ 3 + 1/ 4 … sums logarithmically to infinity to create a "harmonic" stack of n bricks which extend out approximately 1/2 log n.
