physical law describing absorption of light

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed equations to calculate…

The search for a theory of everything spans centuries, from Kepler, Galileo and Newton, to Faraday and Maxwell, to Einstein, Bohr, Dirac, and C.N.Yang, to recent advances in superstring theory.

Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.

Tokamak Energy has achieved a plasma temperature of 100m degrees Celcius, the threshold for commercial fusion energy.

I believe the world is changing in big ways that haven’t happened before in our lifetimes but have many times in history, so I knew I needed to study past changes to understand what is happening now and help me to anticipate what is likely to happen.

I…

A simple algorithm that revolutionizes how neural networks approach language is now taking on image classification as well. It may not stop there.

In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the…

The device could help hunt dark matter or search for gravitational waves, scientists say.
