Physicists have built a real-number version of quantum mechanics that makes all the same predictions as the standard theory, ...

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 ...

The universality phenomenon reveals that certain complex functions arising in number theory—most notably the Riemann zeta‐function and a broad class of L‐functions—are astonishingly rich in analytic ...
