Past neuroscience research suggests that biological neural networks in the brain could self-organize into a critical state. In physics, a critical state is essentially a point that marks the transition between ordered and ...
(PhysOrg.com) -- How do some Web pages become popular? In a recent study, researchers have analyzed Wikipedia articles and a collection of all the Web pages of Chile to better understand the dynamics of online popularity. ...
Glass doesn't have to be brittle. Scientists propose a way of predicting whether a given glass will be brittle or ductile—a property typically associated with metals like steel or aluminum—and assert that any glass could ...
