At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

When I began my master’s program in cognitive science, an electrical engineering professor told us—rather arrogantly—that the soul is nothing but neurons firing. “You’re deluded if you think otherwise ...

More than 200 years ago, the English scientist Thomas Young carried out a famous test known as the “double-slit experiment.” He shone a beam of light at a screen with two slits in it, and observed ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

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 ...

Scientists have revealed how quantum interference and symmetry dictate molecular behavior in collisions with gold surfaces, offering new insights into molecular interactions. The findings can have ...

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 ...

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...
