Many important features of the geometry of high-dimensional spaces can be seen as consequences of concentration of measure on the orthogonal group.  I will illustrate this phenomenon with three examples: the Johnson-Lindenstrauss lemma, Dvoretzky's theorem, and a measure theoretic analog of the latter.  The talk will be elementary and assume no prior knowledge of measure concentration or any of the results to be discussed.
