Science Matters Math Counts Tank Tops
Description: A black background with a stylized orange and yellow shape resembling a mountain or abstract peak. Below this shape, the word "math." is written in large, white sans-serif capital letters. Underneath "math.", the text "THE ONLY SUBJECT THAT COUNTS." is displayed in smaller white capital letters.
Description: A bold yellow and black composition featuring large yellow text that reads "MATH" at the top. Below this, a yellow banner states "THE ONLY SUBJECT". In the center, there is a white calculator, a white ruler, and a white pencil. Mathematical symbols including a plus sign, minus sign, multiplication sign, and division sign are also present. The bottom features large yellow text stating "THAT COUNTS".
Description: In physics and mathematics, and especially differential geometry and gauge theory, the Yang–Mills equations are a system of partial differential equations for a connection on a vector bundle or principal bundle. They arise in physics as the Euler–Lagrange equations of the Yang–Mills action functional. They have also found significant use in mathematics. Solutions of the equations are called Yang–Mills connections or instantons. The moduli space of instantons was used by Simon Donaldson to prove Donaldson's theorem.
