"With this, we can detect very tiny changes in both position and momentum at once, beyond the limit of any classical sensor," ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

A cornerstone of quantum physics is uncertainty. Heisenberg’s uncertainty principle states the more precisely you pinpoint the position of a particle, the less precisely you can know its momentum at ...
