Today was "Sooner Saturday," where high school students come to OU to tour the campus and various departments, get information about coming to OU, etc. I helped with the Math Department's Open House from 11:30-2:30 (really 3:00). There were some slow moments, and another grad student started working on this puzzle that requires you to assemble odd-shaped pieces into a tetrahedron. At one point, he gave up and just stacked all the pieces on the pile. Here's the result (which I dubbed "a tetrahedron after a hard night") from two different angles:
Today's Quote: "There is nothing that can be said by mathematical symbols and relations which cannot also be said by words. The converse, however, is false. Much that can be and is said by words cannot successfully be put into equations, because it is nonsense." -- C. Truesdell
