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 ...

Physicists have measured both the momentum and position of a particle without breaking Heisenberg’s iconic uncertainty principle. In quantum mechanics, particles don’t have fixed properties the way ...

Old physics wisdom can get comically simple. Take, for instance, the idea that bigger is generally better for complex science observatories. But there’s another one that researchers unknowingly gloss ...
