Probing the edge of chaos
The edge of chaos—right before chaos sets in—is a unique place. It is found in many dynamical systems that cross the boundary between a well-behaved dynamics and a chaotic one. Now, physicists have shown that the distribution—or frequency of occurrence—of the variables constituting the phys ... more
Quasi-particle swap between graphene layers
Belgian scientists have used a particle physics theory to describe the behaviour of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In a paper published in EPJ B, Michael Sarrazin from the University of Namur, and Fabric ... more
Clean energy least costly to power America’s electricity needs
It’s less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study published in the Journal of Environmental Studies and Sciences.
In fact—using the official U.S. g ... more
