Title: Is 1 always positive?


Is the integer 1 always positive? Or easier, is the integer 1 always positive in the field of real numbers? No human can answer this "simple" problem over 2000 years. In 1926, E. Artin got the first correct solution to this problem. This talk is about this story and some recent progress in this direction.
