A worthy Theory of Everything needs to look good on a T-shirt, and E8 Theory lives up to the promise. These stylish shirts, designed with the help of Garrett Lisi, show all the known elementary particles of physics and how they interact, matching charges of the E8 Lie group -- perhaps the most beautiful structure in mathematics. For the mathematically inclined, equations on the back explain how it describes our universe. These high quality tri-blend tees come in a super-intelligent shade of blue in a unisex or women's cut. All proceeds go to the Pacific Science Institute — a 501(c)3 with the mission of making life better for scientists.
