There is a fundamental limit to the knowability of the universe. There is a fundamental limit to the knowability of the universe. The Heisenberg uncertainty principle tells us that the more precisely ...

Road less travelled: a photon weaves its way through three slits A flaw in how quantum-interference experiments are interpreted has been quantified for the first time by a team of physicists in India.

Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process ...

Mark Barrett correctly points out that in Richard Feynman's path-integral formulation of quantum mechanics, a particle is in a sense everywhere at once (Letters, 13 October). On the same page, Koos ...

ABSTRACT. We present a comparison among the performance of solvers based on Nyström discretizations of several well-posed boundary integral equation formulations of Helmholtz transmission problems in ...
