When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something ...

Learn how to calculate the speed of a mass in a circular pendulum with this clear physics tutorial! Step-by-step explanations make it easy to understand circular motion, energy, and angular velocity.

In this Letter, we use the lattice formulation of QCD 10, that is, we discretize space-time on a four-dimensional lattice with N t and N s points in the temporal and spatial directions. The lattice ...

Researchers at the University of Bristol in the UK have made a prototype optical quantum computer chip and used it to perform a mathematical calculation for the first time. The device consists of tiny ...

Math whiz Wim Klein, born a century ago, moved physics forward with his calculations as computer developers worked to catch up with him. An audience member yelled: “35, 27, 42, 41.” Wim Klein chalked ...
