Russell's Paradox Long Sleeve Tee
Learn the dangers of the axiom schema of unrestricted comprehension. It only requires a few lines of math to find the contradiction hiding beneath this axiom. Prior to Russell's paradox, the existence of each of the elements of a collection was seen as sufficient for the existence of the set of said elements. That changed with these two lines of math, with a similarly terse proof. 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
