2029 Binomi           Discovered 1969 Sept. 11 by P. Wild at Zimmerwald.
This minor planet, five ahead of (2034) Bernoulli, is named for the mythical inventor of mathematical formulae. It seems that a student, on being asked when Binomi lived, credited him with having been a contempory of Newton, a response that became notorious around the university. A few years later another student, on being asked when Bernoulli lived, immediately answered: "I'm not going to fall into that trap; it is well known that the man never existed!"
