Here are 25 interesting questions published by Glenn Branca in the New York Times in early 2007. I’ve included my responses which are hopefully not too flippant.
Glenn’s intro: “I got the idea for this piece from mathematician David Hilbert’s well-known list of 23 “Paris Problems” (1900) that he hoped to see solved in the new century. Of course there is not the slightest connection between Hilbert’s list of problems and this list of questions. Not to mention the fact that many of these questions contain the answer simply in the asking.”
