Wonderful Art of Paper Folding

A popular belief holds that it is impossible to fold a sheet of paper in half more than 7 times, folding in any direction, as the challenge had existed for many years and had never been solved. This belief was debunked by then high school student Britney Gallivan who successfully folded a piece of paper 12 times. More importantly she developed the mathematical and physical explanations for the actual folding limits of incompressible materials when folding in one or two directions. After the mathematics were developed she demonstrated folding in half 12 times both by folding paper in a single direction and by folding gold foil while rotating the folding 90 degrees after each fold.
