Riemann Hypothesis Long Sleeve Tee ("Proof" on Back)
We have known since 2004 that the first ten trillion nontrivial zeros of the Riemann zeta function lie on the critical line. Ten trillion seems good enough. Why not let your friends, family, and colleagues know that you are ready to give up on proving that this holds for all infinitely many such zeros, and just accept this as an axiom? A bit more formal than a standard-issue t-shirt, the ultra cotton long sleeve tee is a clear comfort winner. The sleeves also act as a nice frame. There are no side seams. The shoulders are taped for improved durability. This makes for a good fitting around the shoulders and neck. The cotton used for these shirts is environmentally friendly. .: 100% cotton (fiber content may vary for different colors).: Medium fabric (6.0 oz/yd² (203 g/m²)).: Classic fit.: Sewn-in label.: Runs smaller than usual
