A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

An international team of researchers shows through a concrete theoretical experiment that the prediction by standard complex quantum theory cannot be expressed by its real counterpart and ratifies its ...

Excel's basic formulas work fine for simple calculations, but they quickly become cumbersome when you're dealing with complex data analysis. You end up with nested functions that are hard to read, ...
