Russian mathematician eats doughnut, wins prize
 [ QUOTE ] CNN MADRID, Spain (AP) -- A reclusive Russian won an academic prize Tuesday, the Fields Medal which was announced at the International Congress of Mathematicians, for work toward solving one of history's toughest math problems. Grigory Perelman, a 40-year-old native of St. Petersburg, was praised for work in the field known as topology, which studies shapes, and for a breakthrough that might help scientists figure out nothing less than the shape of the universe. <font color="white">. </font> The riddle Perelman tackled is called the Poincaré conjecture, which essentially says that in three dimensions, a doughnut shape cannot be transformed into a sphere without ripping it, although any shape without a hole can be stretched or shrunk into a sphere.
