A theorem as old as time… or almost For more than two millennia, Pythagoras’ theorem has stood as one of the cornerstones of geometry. The discovery we’re talking about first made headlines in late ...

A variation of a puzzle called the “pick-up sticks problem” asks the following question: If I have some number of sticks with random lengths between 0 and 1, what are the chances that no three of ...

Is mathematics discovered or invented? Some people believe that mathematics is the language of the universe, and it’s just waiting to be uncovered. Others believe that mathematics is a human construct ...

The Bell theorem stands as an insuperable roadblock in the path to a very desired intuitive solution of the EPR paradox and, hence, it lies at the core of the current lack of a clear interpretation of ...

Inequalities play a central role in physics: They allow us to state universal relations between different quantities. Starting from information-theoretic concepts, we derive an inequality for ...
