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, ...

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 equations that describe physical systems often assume that measurable features of the system — temperature or chemical potential, for example — can be known exactly. But the real world is messier ...

The Uncertainty Engine is guiding research in fusion plasma physics. Could similar approaches benefit fission research as ...

Physics departments chairs around the country have expressed feelings of demoralization, decreased productivity, and a ...

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 ...

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 ...

SOMEWHERE in the literature of the theory of O relativity occurs the statement: “The theory of relativity is physics, and we render it no good service by too hastily attributing to it a philosophical ...
