For the first time, scientists have shown that sound can travel through the emptiness of a vacuum. However, the rule-breaking trick requires specific circumstances and can only be carried out over ...

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment at the Niels Bohr Institute probes these limits, analyzing how quantum ...

Behind every coincidence lies a plan -- in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be explained in ...

Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment probes these limits, analyzing how quantum fluctuations set a sensor ...
