MIT researchers have designed silicon structures that can perform calculations in an electronic device using excess heat instead of electricity. These tiny structures could someday enable more ...

Tropical algebra studies structures over the tropical semiring, where addition is defined as taking a minimum (or maximum) and multiplication as ordinary addition. Within this framework, tropical ...

Mathematicians love a good puzzle. Even something as abstract as multiplying matrices (two-dimensional tables of numbers) can feel like a game when you try to find the most efficient way to do it.
