Queens College Of The City Of New York 1937 Bronze Medal From Prof Arthur Sard

This is a one of a kind item that belonged to professor Arthur Sard. He was a very famous mathematician. Arthur Sard was an American mathematician known for Sard's Theorem, a fundamental result in differential topology and analysis stating that the set of critical values (the image of critical points) of a smooth function between manifolds is a "small" set, meaning it has Lebesgue measure zero. His work, particularly on critical values and linear approximation, proved crucial for understanding generic properties of functions and manifolds, establishing that "bad" points where derivatives fail to have full rank are rare.
