Today, Jan 12, we remember Hermann Minkomski's death anniversary. Hermann Minkowski was a Jewish German mathematician. He used geometrical methods to solve problems in the special relativity theory of Einstein. Minkowski is perhaps best known for his foundational work describing space and time as a four-dimensional space, now known as "Minkowski spacetime".
