Zoltan Fodor receives funding from DFG, BMBF. When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at ...

The most powerful formula in physics starts with a slender S, the symbol for a sort of sum known as an integral. Further along comes a second S, representing a quantity known as action. Together, ...

Visiting all the children on Earth in one night requires serious horsepower (or, reindeerpower?) and now we know exactly how much. According to research carried out by undergraduates at the University ...
