Inspired by Mathematics? Always doing some calculations in your head? Well…here’s something to keep you even more motivated. Check out the Math Mug, totally for the math geeks. Formulas everywhere and high caffeine (coffee) content; two of the most important things.

As ThinkGeek explains, “Each mug is covered in diverse and important formulae. From the very basic (simple addition: 1+1=2) to the more complex (Planck’s equation: E=hv), you’ll never be at a loss for an equation. What’s even better is that each formula is labeled, so each time you drink you’ll learn something too.”

Price? $9.99
