force : any of the natural influences (as electromagnetism, gravity, the strong force, and the weak force) that exist especially between particles and determine the structure of the universe — Webster
Forces in the universe are based on four fundamental interactions. The strong and weak forces are nuclear forces that act only at very short distances, and are responsible for the interactions between subatomic particles, including nucleons and compound nuclei. The electromagnetic force acts between electric charges, and the gravitational force acts between masses. All other forces in nature derive from these four fundamental interactions. For example, friction is a manifestation of the electromagnetic force acting between the atoms of two surfaces, and the Pauli exclusion principle, which does not permit atoms to pass through each other. Similarly, the forces in springs, modeled by Hooke’s law, are the result of electromagnetic forces and the Exclusion Principle acting together to return an object to its equilibrium position. Centrifugal forces are acceleration forces that arise simply from the acceleration of rotating frames of reference — Wikipedia

Wigner crystal -- not Mott insulator -- in...
on September 24, 2018 at 9:44 pm
Recently, scientists created a stir in the field of condensed matter physics when they showed that two sheets of graphene twisted at specific angles display two emergent phases of matter. After a careful review of the experimental data researchers say that the insulating behavior of the ''magic-angle'' graphene is not Mott insulation, but something even more profound -- a Wigner crystal. […]

DNA tests bring together French son of GI and US...
on September 24, 2018 at 11:33 pm
A Frenchman who spent his whole adult life searching for his American father, a soldier who fought in Europe during World War Two, said he was "bowled over" after coming face-to-face with a previously unknown half-brother on Monday thanks to a chance DNA breakthrough. […]
Scientists search for coral's new home

Coral reefs have long faced problems like overfishing, global warming and pollution—but they're also threatened by how slow they regenerate. […]
Research forecasts US among top nations to suffer...
on September 24, 2018 at 3:00 pm
For the first time, researchers have developed a data set quantifying what the social cost of carbon—the measure of the economic harm from carbon dioxide emissions—will be for the globe's nearly 200 countries, and the results are surprising. Although much previous research has focused on how rich countries benefit from the fossil fuel economy, while damages accrue primarily to the developing world, the top three counties with the most to lose from climate change are the United […]

Satellite radio titan SiriusXM unveiled plans Monday to acquire online rival Pandora for $3.5 billion, ramping up competition in the streaming music market dominated by Spotify and Apple. […]
After the Big One: Understanding aftershock risk
on September 24, 2018 at 12:53 pm
In early September 2018, a powerful earthquake on the island of Hokkaido in northern Japan triggered landslides, toppled buildings, cut power, halted industry, killed more than 40 people and injured hundreds. The national meteorological agency warned that aftershocks could strike for up to a week following the main event. […]
