What do all these moments in time on this planet mean for each and every one of us? What do we make of our lives when we look back on them? Where do we find comfort? These are some of the questions ...

For three centuries, the concepts of particle and wave have been dichotomous. Famous is the dispute about the nature of light between Newton, who believed light had a particle nature, and Hooke and ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

A new experiment captures a single parcel of light morphing between wave and particle. Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon ...

It’s in your physics textbook, go look. It says that you can either model light as an electromagnetic wave OR you can model light a stream of photons. You can’t use both models at the same time. It’s ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
