The new measurement, based on just one month of data, cuts the possible upper limit of the neutrino mass in half, compared with the best previous estimate from a direct-measurement experiment.

Measurements on quantum systems have puzzled generations of physicists due to their counterintuitive properties. One of them is the fact that measurements on a quantum system are in general non ...

A Vermont research team has cracked a 90-year-old puzzle, creating a quantum version of the damped harmonic oscillator. By reformulating Lamb’s classical model, they showed how atomic vibrations can ...

Optical-lattice clocks have pushed the limits of frequency measurement — to such an extent that a tiny difference in altitude affects the clock's tick rate, as Hidetoshi Katori elucidates.

To make things easier, here are 9 smart, easy-to-follow tips that will help you understand and enjoy physics concepts related to forces and motion.
