"Einstein and Gödel," by David Berlinski. Discover, March 2002, pages 38-43.
David Berlinski's article offers insight into the unique friendship that developed between Albert Einstein and Kurt Gödel while they were members of Princeton's Institute for Advanced Study. Gödel's incompleteness theorems did for mathematics what Einstein's theory of relativity did for physics---profoundly changed the given rules. Berlinski shows how their very different personalities played out in their relationship and scientific affinities.
