When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Recent work suggests that a single photon might be detected in more than one spot simultaneously. Some see this as a reason to reconsider the idea of alternate universes interacting behind the scenes.

An advanced version of the famous double-slit experiment has directly measured a single photon in two places at once – or at least, that’s the claim made by a team of physicists who say these results ...

‘Particles caught morphing into waves’ was how a recent preprint from researchers in France was widely reported. The timing could not have been better, for this year is the centenary of Louis de ...

Woody debris flows (i.e., debris flows carrying wood) are common in mountainous and forested areas. They can cause more severe hazards due to the effects of LW (woody debris larger than 1 m in length ...

In this review, we summarize the recent efforts on manipulating phonon transport in solids by using specific techniques that modify their phonon thermal conductivity (i.e., specific heat, phonon group ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

Or was it? Weirdly, in experiments centuries later in which researchers took care to shine only one photon at a time toward the wall, the interference pattern remained, as if a single particle were ...

Is nature inherently random? According to some interpretations of quantum mechanics, it is, explaining why we can’t precisely predict the motions of single particles. In the famous double-slit ...
