Physicists shed light on a different kind of chaos

Physicists at UC Santa Barbara, the University of Maryland, and the University of Washington have found an answer to the longstanding physics question: How do interparticle interactions affect dynamical localization?

The older we get, the less we know (cosmologically)

(Phys.org) -- The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over ...

Lightning strokes can probe the ionosphere

(Phys.org) —Thunderstorms, and the resulting partially ionized plasma of the ionosphere, can distort radio signals traveling to satellites important to communications, navigation or national security

The new world of gamma-ray optics

Scientists discover that certain materials like silicon or gold exhibit a surprisingly large refractive index for extremely high energetic gamma-rays.

Researchers reveal unseen planet by its gravity

More than a 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier predicted the planet's existence based on small deviations in the motion of Uranus. In a paper published ...
