A breakthrough that got credit for “simplifying” quantum physics could wipe away some of its more troubling contradictions by pointing out that even those who can calculate it precisely don’t always ...

In a first-of-its-kind experiment, researchers have captured quantum uncertainty in real time using ultrafast pulses of light. Nearly a century after Werner Heisenberg proposed the uncertainty ...

In quantum mechanics, it is impossible to know both exactly where you are and exactly where you are going. This idea, known as Heisenberg’s uncertainty principle, has been a key part of studying the ...

Accurately tracking atmospheric greenhouse gases requires not only fast predictions but also reliable estimates of ...
