ABSTRACT  |  Local realism was introduced by Einstein, Podolsky and Rosen as a reasonable physical principle that is a hallmark of classical physics. It was subsequently shown by Bell that local realism is violated by quantum theory and it can be argued that this was the birth of quantum information science. In this talk, I would like to introduce a new principle - the triangle principle. The triangle principle allows us to derive all known state dependent non-contextual inequalities and bipartite local realistic inequalities in a simple geometrical way. It also introduces the concept of monogamy of such inequalities as its generic feature. I will end with a discussion of the Holy Grail of research on quantum contextuality: Is quantum contextuality a valuable resource?
