Recent News:Physicists 'bootstrap' validity of string theoryString theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that points to its 'inevitability.' more... String figures shed light on cultural connections and the roots of mathematical reasoningNew research suggests that the making of string figures, a globally documented practice, may point to shared cultural heritage stretching back millennia. The research offers a new way to investigate the evolution and distribution of cultural phenomena using mathematical methods. more... Physics and emote design: Quantifying clarity in digital imagesWhen analyzing artworks, understanding the visual clarity of compositions is crucial. Inspired by digital artists, researchers have created a metric to quantify clarity in digital images. As a result, scientists can accurately capture changes in structure during artistic processes and physical transformations. This new metric can improve analysis and decision-making across the scientific and creative domains, potentially transforming how we understand and evaluate the structure of images. It has been tested on digital artworks and physical systems. more... Leap in modelling human impact on climate may lead to early warning of climate disastersMathematicians have applied statistical mechanics to climate change detection and attribution for first time. They have shown how to separate the 'signal' of human-made climate change from the 'noise' of natural climate fluctuations. This allows for a dramatic improvement in the ability to detect climate change and early warnings of climatic tipping points. more... New AI cracks complex engineering problems faster than supercomputersModeling how cars deform in a crash, how spacecraft responds to extreme environments, or how bridges resist stress could be made thousands of times faster thanks to new artificial intelligence that enables personal computers to solve massive math problems that generally require supercomputers. more... How neighborhood enhances cooperationHelping out your neighbor or minding your own business? A challenging choice with different benefits for each decision. Game theory provides guidance in making such choices -- from a theoretical perspective. Novel findings reveal new network structures that enhance cooperation throughout a system. These insights have potential applications also in biology. more... X-ray vision: Seeing through the mystery of an X-ray emissions mechanismSince the 1960s, scientists who study X-rays, lightning and similar phenomena have observed something curious: In lab experiments replicating these occurrences, electrons accelerated between two electrodes can be of a higher energy than the voltage applied. According to researchers, this defies an assumption in physics that the energy of the electrons should correspond with the voltage applied. Despite the decades-long awareness of this apparent contradiction, researchers couldn't figure out why this was happening. Recently, a team of researchers used mathematical modeling to explain the underlying mechanism at play. more... |
