The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what’s called the “Copenhagen interpretation” — which holds that, in some sense, a single particle really is a wave, smeared out across the universe, which collapses into a determinate location only when observed.

Discovering a brain tumor is a very serious issue, but it is not the end of the story. There are many different types of brain tumor with different survival rates and different methods for treatment. However, today, many brain tumors are difficult to clearly diagnose, leading to poor prognoses for patients.
Dinosaurs and mathematics do not seem like an obvious pair, but for Robert Sinclair and his Mathematical Biology Unit, they are a logical match. Sinclair was part of a team that recently published a paper reexamining the classification of a dinosaur bone found. Using his expertise in mathematics, Sinclair was able to help reclassify a single arm bone as belonging to a dinosaur family previously believed not to have existed ...
On the eve of the 2014 FIFA World Cup, researchers investigated the productivity of top goal scorers in international football. The RMIT University team applied advanced econometric techniques to a sample of 66 top goal scorers in the Union of European Football Associations (UEFA) Champions League between 1991 and 2011.
There are some 100 million other places in the Milky Way galaxy that could support complex life, report a group of university astronomers in the journal Challenges. They have developed a new computation method to examine data from planets orbiting other stars in the universe. Their study provides the first quantitative estimate of the number of worlds in our galaxy that could harbor life above the microbial level.
Nelson Mandela said: “We must use time wisely and forever realize that the time is always ripe to do right.” Time series data have a temporal order that makes analysis distinctly different from other data analysis. The goal of time series analysis can be divided into characterization or prediction.
I can most simply describe this book by quoting from the back cover: Motivation — “…how can you get started in a wide-ranging, interdisciplinary field that’s so clouded in hype?” Background Needed — “If you’re familiar with linear algebra, probability, and statistics, and have programming experience…”
Celebrated portrait photographers like Richard Avedon, Diane Arbus, and Martin Schoeller made their reputations with distinctive visual styles that sometimes required the careful control of lighting possible only in the studio. Now, MIT researchers and their colleagues at Adobe Systems and the University of Virginia, have developed an algorithm that could allow you to transfer those distinctive styles to your own cellphone photos.

Suppose you’re trying to navigate an unfamiliar section of a big city, and you’re using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns and, for a while, you lose sight of your landmarks. When they reappear, in order to use them for navigation, you have to be able to identify them as the same buildings you were tracking before — as well as your orientation...
By the end of the 21st century, some parts of the world can expect as many as 30 more days a year without precipitation, according to a new study by Scripps Institution of Oceanography, UC San Diego researchers. Ongoing climate change caused by human influences will alter the nature of how rain and snow falls; areas that are prone to dry conditions will receive their precipitation in narrower windows of time.
Antarctica's Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica.
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology. Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory — how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature.
NAG Library for Java Release 2 enables the calling of precisely 1,784 mathematical and statistical routines to aid complex computation, and enhanced error reporting enables increased precision from computation results. It provides abstract classes for callback functions.
Behind every “Top 100” list are a generous sprinkling of personal bias and subjective decisions. However, the first dynamic visualization software of its kind, LineUp allows users to assign weights to different parameters to create a custom ranking.
The National Energy Research Scientific Computing (NERSC) Center recently accepted “Edison,” a new flagship supercomputer designed for scientific productivity. Named in honor of American inventor Thomas Alva Edison, the Cray XC30 will be dedicated in a ceremony held at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) on February 5, 2014, and scientists are already reporting results.
An international team of scientists has discovered that two of the world's most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s. These findings suggest a...
The sweltering year of 1988 first put global warming in the headlines and ended up as the hottest year on record. But on January 21, 2014, it was pushed out of the top 20 warmest by 2013. Last year tied for the fourth hottest and 1988 fell to 21st.
MathWorks announced that The Nobel Foundation has adopted MATLAB to support the asset-liability management strategies of its $500 million (3.3 billion kronor) portfolio and meet its long-term goal of providing monetary awards to future Laureates.
The Gordon and Betty Moore Foundation announced an open call for applications for its brand-new Data-Driven Discovery Investigator competition. The foundation seeks individuals who exemplify multidisciplinary, data-driven science, coalescing natural sciences with methods from statistics and computer science.
Josiah Stamp said: “The individual source of the statistics may easily be the weakest link.” Nowhere is this more true than in the new field of text mining, given the wide variety of textual information. By some estimates, 80 percent of the information available occurs as free-form text which, prior to the development of text mining, needed to be read in its entirety in order for information to be obtained from it.
