Black Math Watch
Mathematics is made of 50 percent formulas, 50 percent proofs, and 50 percent imagination. If this sounds just right to you, you might actually need this watch.
Otherwise, just give it as a gift to one of your more math-versed friends of family members who dream equations or just love a difficult equation or a good math joke.
Oh, this nerdy watch goes well as a gift when accompanied by the Black Math Wall Clock or the really great book Zero: The Biography of a Dangerous Idea that will make their wheels turn in their excited brains.
- Each hour has been replaced with an equation that gives out the number
