The great day approaches–April 15! No, no, not Tax Day–nothing so trivial. It is the 200th birthday of Leonhard Euler, the great Swiss mathematician–the greatest mathematician of all on Charles Murray’s ranking.

I have a long article on the great man in the upcoming (early April) issue of the Wilson Quarterly.

This should not be taken as in any way an endorsement of the 18th President, about whom I have grave misgivings.
