John Willard Milnor

John Willard Milnor is an influential American mathematician known for his groundbreaking work in topology, differential geometry, and singularity theory. He made significant contributions to our understanding of multi-dimensional shapes, introducing concepts like "exotic" spheres—manifolds that are indistinguishable from standard spheres but have different properties. Milnor's work has deep implications across mathematics and physics, particularly in understanding the structure of space and the nature of higher dimensions. He was awarded the Fields Medal in 1962, highlighting his impact and innovation in the mathematical sciences.
