Exponential Growth in Paper Folding

The video tutorial explores the mathematics of folding a piece of paper. It begins by demonstrating how folding a paper in half doubles its thickness and reduces its size. As folding continues, the number of layers increases exponentially while the area decreases. The tutorial introduces a power law to describe the relationship between folds and layers, showing that the number of layers equals two raised to the power of the number of folds. The video concludes by unfolding the paper to validate the mathematical principles, emphasizing that any number raised to the power of zero equals one.

What happens to the thickness of a piece of paper when it is folded in half?
