In the early 1920s, physicists were first working out the mysteries of the quantum Universe. Particles sometimes behaved as waves, with indeterminate positions, momenta, energies, and other properties ...

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a particle's position and momentum cannot be known at the same time with absolute ...

A cornerstone of quantum physics is uncertainty. Heisenberg’s uncertainty principle states the more precisely you pinpoint the position of a particle, the less precisely you can know its momentum at ...
