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

Magnetic fields around black holes decay quickly, researchers report. This finding backs up the so-called 'no-hair conjecture' predicted by Einstein's general relativity.

Anyone who has ever failed to throw a beer mat into a hat should take note: physicists have discovered why this task is so difficult. However, their study also suggests how to significantly increase accuracy and range.

When a compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, it transitions from an insulator into a metallic state and back into an insulator. This is accompanied by unprecedented decreases in resistance and volume across an extremely narrow range of pressure changes at room temperatue, say researchers.

Researchers have developed a method that uses a gaming graphics card to control plasma formation in their prototype fusion reactor.
- Antimatter from laser pincerson July 22, 2021 at 3:30 pm
An international physics team has proposed a new concept that may allow selected cosmic extreme processes to be studied in the laboratory in the future. A special setup of two high-intensity laser beams could create conditions similar to those found near neutron stars, for example. An antimatter jet is generated and accelerated very efficiently, as the experts report.

Coffee shops and casual restaurants are an important part of American life. Even beyond the food and drinks they sell, they offer us a place to use the restroom or rest our feet while we're out and about, and they provide internet access to those on the go, those in need of a temporary office, or those who don't have an internet connection at home. Many of us take for granted that a nearby Starbucks or McDonald's can offer us a little respite, even if we don't always make a purchase.
