Positivity is about much more than the set of positive numbers. This talk is intended as an illustration of how the concept of positivity is playing a fundamental role in several areas of mathematics and science. I will then focus on its meaning in some of my own research, which lies in the theory of operator algebras. Some special cases of the latter have applications in the young and influential research area of quantum information theory.
