Physicists are teasing a potential leap in nuclear fusion that sounds almost absurd on its face: a path to reactions that are ...

An innovative arrangement employing diverse electronic and optical principles and components leads to precision frequency ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

THE approach to probability adopted in this book is conventional, but cautious. The two definitions, the one a priori, based on equally likely aspects of a system, the second a posteriori, based on ...
