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 ...
