(Phys.org) —In theory, Maxwell's demon can decrease the entropy of a system by opening and closing a door at appropriate times to separate hot and cold gas molecules. But as physicist Leó Szilárd pointed ...
Scientists of the universities in Düsseldorf and Kiel have obtained a surprising result that appears to be in conflict with standard text book knowledge. According to the fundamental Bohr-van Leeuwen theorem, ...
Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules—specifically, a protein ...
(Phys.org) —In a Perspective in Science magazine this week, a Stanford Professor of Statistics re-examines Bayes' Theorem, its varying fortunes over the two-and-a-half centuries since it was proposed, and ...
General theory of meromorphic functions in the complex plane began in the nineteenth century, when E. Picard proved his famous 'Picard's little theorem'. Then, in the 1920s, R. Nevanlinna created the modern ...
Kenneth Appel, a mathematician who was the first to use a computer to prove a century-old major mathematical theorem, has died at age 80 in Dover, N.H.
Fermat's Last Theorem—the idea that a certain simple equation had no solutions— went unsolved for nearly 350 years until Oxford mathematician Andrew Wiles created a proof in 1995. Now, Case Western Reserve University's ...
A new study analyzing the previous math standards of each state provides strong support for adoption of common standards, which U.S. students desperately need to keep pace with their counterparts around the globe, a Michigan ...
At 5:46 p.m. on Sept. 20, Georges Gonthier, principal researcher at Microsoft Research Cambridge, sent a brief email to his colleagues at the Microsoft Research-Inria Joint Centre in Paris. It read, in full: ...
(Phys.org)—As solar cell technology matures, researchers continue to look for ways to develop ever-thinner technology to reduce material costs. Such technology also reduces the distance electrons and holes, ...
The myth that mathematical theorems suddenly come together in the most elegant and smooth proofs will be busted at an upcoming lecture.
(PhysOrg.com) -- For fifty years, mathematicians have grappled with a so-called “fixed point” theorem. An EPFL-based team has now found an elegant, one-page solution that opens up new perspectives ...
A dynamical system in which repeated measurements on a single particle yield the same mean result as a single measurement of the whole ensemble is said to be ergodic. The ergodic theorem expresses a fundamental physical principle, ...
Google paid tribute on Wednesday to 17th century French mathematician Pierre de Fermat, transforming its celebrated homepage logo into a blackboard featuring "Fermat's Last Theorem."
