For the first time ever, physicists have mapped the path that particles are most likely to take when moving from one quantum state to another. In physics, a concept called the "path of least action" ...

The path of a smart particle is color-coded to indicate the temperatures it wirelessly reports back during its travels. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

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 ...
