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 ...

In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both be known fully precisely at the same time. Researchers now show that two ...

Last week, physicists at the National Institute for Standards and Technology reported they'd cooled an object to a million times colder than room temperature. It was a record for the super-difficult ...
