Tau Day - A Perfect Day! Tshirts


A shirt for Pi Day's eventual replacement -- Tau Day! Show the world your love for math and this date with a true geek's t-shirt. The date 6/28 is better than 3/14 because 6 and 28 are perfect numbers. Plus, lots of math folks think tau (6.28) is a number that ought to be celebrated more than pi (3.14), since it naturally occurs in so many formulas.
