The advent of laser cooling revolutionized the field of atomic physics, transforming atomic clocks and GPS technology and laying the foundations for quantum computing with atoms and ions. In the first ...

A person talking about how uncertain they are might seem less than confident, but for scientists, it can be quite the opposite. Providing the measure of uncertainty ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more ...
