The rules of statistical physics address the uncertainty about the state of a system that arises when that system interacts with its environment. But they've long missed another kind. In a new paper, ...

Uncertainty is part of life. There's just no escaping it, even in a science as precise as nuclear physics. While scientists work to develop ideas and experiments to minimize that uncertainty, they ...

I like to believe that we embody the names we are given. And since my name is Joyful, I’ve always defaulted to this mental state even in periods of uncertainty. People have repeatedly commented that ...

The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all ...

The uncertainty principle states that we cannot know the state of a system with arbitrary precision. Now the uncertainty relation between angular momentum and position has been measured in an ...

Drawing on captured Nazi documents found in Soviet archives and other recently released materials, Cassidy (J. Robert Oppenheimer and the American Century) offers a new view of the German wunderkind ...

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 ...
