Surprising preference for simplicity found in common model
Mar 12, 2018 feature
Researchers have discovered that input-output maps, which are widely used throughout science and engineering to model systems ranging from physics to finance, are strongly biased toward producing simple outputs. The results ...
Researchers validate several fluctuation theorems for first time
Feb 23, 2018
Researchers at Purdue University have performed the first experimental tests of several fundamental theorems in thermodynamics, verifying the relationship between them and providing a better understanding of how nanoparticles ...
Physicists extend stochastic thermodynamics deeper into quantum territory
Feb 13, 2018 report
Physicists have extended one of the most prominent fluctuation theorems of classical stochastic thermodynamics, the Jarzynski equality, to quantum field theory. As quantum field theory is considered to be the most fundamental ...
Mathematical theorem finds gerrymandering in PA congressional district maps
Feb 28, 2017
Pennsylvania's congressional district maps are almost certainly the result of gerrymandering according to an analysis based on a new mathematical theorem on bias in Markov Chains developed by Carnegie Mellon University and ...
Coding theorem defines decoding error capacity for general scenarios
Dec 27, 2016
The rate at which information can be coded so that it can be decoded within a particular error probability constraint is one of the "major research topics in information theory" as Hideki Yagi at the University of Electro-Communications, ...
Remembering when Wiles proved Fermat's Last Theorem

The golden anniversary of black-hole singularity
Oct 01, 2015
When a star collapses forming a black hole, a space-time singularity is created wherein the laws of Physics no longer work. In 1965 Sir Roger Penrose presented a theorem where he associated that singularity with so-called ...
Seeking proof for the no-hair theorem
Sep 09, 2014
According to general relativity, a black hole has three measurable properties: mass, rotation (angular momentum), and charge. That's it. If you know those three things, you know all there is to know about the black hole. ...
Study explains how Maxwell's demon uses mutual information to extract work
Aug 04, 2014 feature
(Phys.org) —Maxwell's demon, the hypothetical doorman that controls how particles travel between two chambers in an attempt to decrease entropy, is at its heart a feedback-controlled system. The demon makes measurements ...
