Published Rational neural network advances machine-human discovery
(via sciencedaily.com) Math is the language of the physical world, and some see mathematical patterns everywhere: in weather, in the way soundwaves move, and even in the spots or stripes zebra fish develop in embryos.
Published Quantum information theory: Quantum complexity grows linearly for an exponentially long time
(via sciencedaily.com) Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems -- for example, black holes and wormholes in the universe. Now, researchers have proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge.
Published Chaos theory provides hints for controlling the weather
(via sciencedaily.com) Researchers have used computer simulations to show that weather phenomena such as sudden downpours could potentially be modified by making small adjustments to certain variables in the weather system. They did this by taking advantage of a system known as a 'butterfly attractor' in chaos theory, where a system can have one of two states -- like the wings of a butterfly -- and that it switches back and forth between the two states depending on small changes in certain conditions.
Published Mathematical paradoxes demonstrate the limits of AI
(via sciencedaily.com) Humans are usually pretty good at recognizing when they get things wrong, but artificial intelligence systems are not. According to a new study, AI generally suffers from inherent limitations due to a century-old mathematical paradox.
Published Are conferences worth the time and money?
(via sciencedaily.com) Original source Scientists who interact with others during assigned sessions at conferences are more likely to form productive collaborations than scientists who do not, researchers found. And the kicker? It doesn't matter whether the conference is in person or virtual.
Published Brain-based computing chips not just for AI anymore
(via sciencedaily.com) With the insertion of a little math, researchers have shown that neuromorphic computers, which synthetically replicate the brain's logic, can solve more complex problems than those posed by artificial intelligence and may even earn a place in high-performance computing. Neuromorphic simulations employing random walks can track X-rays passing through bone and soft tissue, disease passing through a population, information flowing through social networks and the movements of financial markets.
Published A cautionary tale of machine learning uncertainty
(via sciencedaily.com) A new analysis shows that researchers using machine learning methods could risk underestimating uncertainties in their final results.
Published Mathematical discovery could shed light on secrets of the Universe
(via sciencedaily.com) How can Einstein's theory of gravity be unified with quantum mechanics? It is a challenge that could give us deep insights into phenomena such as black holes and the birth of the universe. Now, a new article presents results that cast new light on important challenges in understanding quantum gravity.
Published Dark energy: Neutron stars will tell us if it's only an illusion
(via sciencedaily.com) Scientists provide the first simulation of neutron star collisions in extensions of general relativity relevant for cosmology, offering a new approach to test gravity.
Published For new insights into aerodynamics, scientists turn to paper airplanes
(via sciencedaily.com) Original source A series of experiments using paper airplanes reveals new aerodynamic effects, a team of scientists has discovered. Its findings enhance our understanding of flight stability and could inspire new types of flying robots and small drones.
