The science-fiction writer Isaac Asimov died more than two decades ago, but that did not stop him from writing about a trip to the World’s Fair of 2014. Fifty years ago, Asimov walked into the GE exhibition at the New York World’s Fair of 1964 and declared that “the direction in which man is traveling is viewed with buoyant hope, nowhere more so than at the General Electric pavilion.”
Stingrays swim through water with such ease that researchers from the University at Buffalo and Harvard University are studying how their movements could be used to design more agile and fuel-efficient unmanned underwater vehicles. The vehicles could allow researchers to more efficiently study the mostly unexplored ocean depths, and they could also serve during clean up or rescue...
A famous math problem that has vexed mathematicians for decades has met an elegant solution by Cornell researchers, who presented a geometric solution for the von Neumann-Day problem, first described by mathematician John von Neumann in 1929.
According to sports legend and entrepreneur Earvin “Magic” Johnson, the game of basketball is math and science in motion — geometry, physics and even chemistry help bring the game to life. The five-time NBA champion and Chairman and CEO of the television network ASPiRE has joined with Time Warner Cable to expand its STEM in Sports campaign.
When an E. coli cell divides, it must replicate its circular chromosome and pull the resulting circles apart to take up residence in two new cells. It sounds easy enough — like a magician's trick with rings — but actually involves a complicated process of unknotting and unlinking of tangled DNA. In a new study, an international team of scientists offers a mathematical analysis of how these rings are unlinked by XerCD recombination enzymes.
Theoretical physicist Frank Wilhelm-Mauch and his research team at Saarland University have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study of one hundred light quanta (photons) and their complex quantum mechanical relationships ("quantum...
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested. One of the basic concepts in the world of quantum mechanics is that it is impossible to observe physical objects without affecting them in a significant way; there can be no measurement without disturbance.
A brain region activated when people are asked to perform mathematical calculations in an experimental setting is similarly activated when they use numbers — or even imprecise quantitative terms, such as "more than"— in everyday conversation, according to a study by Stanford University School of Medicine scientists.
Jack Dongarra of the University of Tennessee will receive the ACM-IEEE Computer Society Ken Kennedy Award for his leadership in designing and promoting standards for mathematical software used to solve numerical problems common to high performance computing (HPC). His work has led to the development of major software libraries of algorithms and methods that boost performance and portability in HPC environments
NAG Toolbox for MATLAB 24 features a total of 1,500 math and statistics functions. The toolbox complements MATLAB by allowing use of NAG and MATLAB functions concurrently.
Kids everywhere grumble about homework. But their complaints will hold no water with a group of theoretical physicists who’ve spent almost 50 years solving one homework problem — a calculation of one type of subatomic particle decay aimed at helping to answer the question of why the early universe ended up with an excess of matter.
A bioinformatics approach to repurposing drugs resulted in identification of a class of antidepressants as a potential new treatment for small-cell lung cancer (SCLC), according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research.
A new study of the brain of a maths supremo supports Darwin’s belief that intellectual excellence is largely due to “zeal and hard work” rather than inherent ability. Neuroscientists took fMRI scans of champion “mental calculator” Yusnier Viera during arithmetical tasks that were either familiar or unfamiliar to him and found that his brain did not behave in an extraordinary or unusual way.
The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence of complex states in the ancient world.
David Brown has been the director of the Computational Research Division at Berkeley Lab since August 2011. An applied mathematician by training, his research expertise and interests lie in the development and analysis of algorithms for the solution of PDEs. His research has focused on adaptive composite overlapping grid techniques for solving PDEs in complex moving geometries and in the analysis of difference approximations for PDEs.
In the wake of deadly tornadoes in Oklahoma this past spring, researchers have developed a new statistical model that will help determine whether the risk of tornadoes is increasing and whether they are getting stronger. Climatologists have been hampered in determining actual risks by what they call a population bias: That is, the fact that tornadoes have traditionally been underreported in rural areas compared to cities.
One way to study criminal behavior and predict a criminal's next move is by analyzing his or her movement. Several mathematical models have addressed this in detail, in particular, the UCLA "burglary hotspot" model, also the topic of a previous Nugget published by the Society for Industrial and Applied Mathematics (SIAM).
The migration of mature female tiger sharks during late summer and fall to the main Hawaiian Islands, presumably to give birth, could provide insight into attacks in that area, according to a University of Florida scientist. In a new seven-year study, researchers used data modeling to analyze the predators' movements in the Hawaiian archipelago, where recent shark incidents have gained international attention
A team of mathematicians has solved a problem first posed more than 40 years ago that has confounded modern mathematicians, until now. The famous Rota's Conjecture has been proved by Professor Jim Geelen of the University of Waterloo and his colleagues, Professor Bert Gerards of Centrum Wiskunde & Informatica and the University of Maastricht in the Netherlands, and Professor Geoff Whittle of Victoria University of Wellington
During the Cold War, U.S. and international monitoring agencies could spot nuclear tests and focused on measuring their sizes. Today, they’re looking around the globe to pinpoint much smaller explosives tests. Sandia National Laboratories and Los Alamos National Laboratory have partnered to develop a 3-D model of the Earth’s mantle and crust called SALSA3D, or Sandia-Los Alamos 3D.
Philadelphia, PA—One of the lesser known concerns about commercial aircraft is their stability on the ground during taxiing, takeoff, and landing. During these processes, planes must maintain stability under various operating conditions. However, in some situations, the aircraft landing gear displays unwanted oscillations, which are referred to as shimmy oscillations.
Reservoirs of silica-rich magma – the kind that causes the most explosive volcanic eruptions – can persist in Earth's upper crust for hundreds of thousands of years without triggering an eruption, according to new University of Washington modeling research.
By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers from Radboud University Nijmegen have succeeded in determining which letter a test subject was looking at. The journal Neuroimage has accepted the article
New computational techniques developed at Lawrence Berkeley National Laboratory (Berkeley Lab) may help save scientists from drowning in their own data. Computational scientists at the Lab have figured out how to streamline the analysis of enormous scientific datasets. The analysis uses the same techniques that make complex subway systems understandable at a glance.
Investigators at Disney Research, Zürich have developed a method for using hundreds of photographic images to build 3D computer models of complex, real-life scenes that meet the increasing demands of today's movie, TV and game producers for high-resolution imagery.
