Measuring the world precisely is much harder than it sounds. At very small scales, ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

Get a clear overview of Physics Chapter 1, focusing on units, measurements, and scientific notation. This video explains how physicists use standard units and powers of ten to express physical ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

We know how to derive most fundamental constants from conditions of the universe, models This is an accurate description of physics as a whole, but wildly untrue in particle physics. There are 25 ...

The 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois. Reidar Hahn, Fermilab About 50 years ago, physicists came up ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...
