A team of mathematicians has wowed the math world with their discovery of a new kind of pentagon┬ácapable of “tiling a plane”–that is, fitting together on a flat surface without overlapping or leaving any gaps. It’s said to be only the fifteenth such pentagon ever found and the first new one to be found in 30 years. Finding one is a bit like discovering a new atomic particle, Dr. Casey Mann, associate professor of mathematics at the University of Washington in Bothell and a member of the team, said in a written statement.
