It goes on to describe the great debate of the last thirty years between science and social science that has called into question the existence of objective risk and focused us upon the social processes that determine risk.

Let .~" be a family of 2 "+1 subsets of a 2n-element set. Then the number of disjoint pairs in ~" is bounded by (1 + o(1))22". This proves an old conjecture of Erd/Ss. Let ~" be a family of 2 tl/tk+l~+~" subsets of an n-element set. Then the number of containments in ,~ is bounded by / I~1 'X (1 1/k + o(1)) k 2 :" This verifies a conjecture of Daykin and Erd/Ss. A similar Erd6s-Stone type resul...
