In 1956 John Milnor startled the mathematical community by
constructing smooth 7-dimensional manifolds that are homeomorphic but
not diffeomorphic to the standard seven-sphere. His discovery opened a
new branch of research in topology and won him the Fields Medal in
1962. In this animation we present Milnor's construction and give a
way of visualizing these manifolds.
