Kinetic instabilities commonly arise from anisotropic (different properties in different directions) electron velocity distributions within ionospheric, cosmic and terrestrial plasmas. But only a handful of experiments have ...
A team of physicists and computer scientists at ETH Zurich has developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves ...

A team of researchers with members from several institutions in the U.S. and one in France has created a two-dimensional chiral fluid that mostly follows hydrodynamics theories. In their paper published in the journal Nature ...
In a kaleidoscope, mirrors are placed at angles to create a visual illusion of multiple, symmetric images from one original object. The number of symmetric axes in the kaleidoscope depends on the number of mirrors and angles ...
