Power of Mathematics Opens New Possibilities in Music

August 27, 2014 3:34 pm | by Steve Koppes, University of Chicago | News | Comments

Anthony Cheung’s formal mathematical training essentially ended with high school calculus. But as a musician and composer, he has explored mathematical phenomena in new ways, especially through their influence on harmony and timbre. “Through technology and thinking about acoustics, we can change sounds on the computer in innumerable ways,” says Cheung, whose musical composition earned him a 2012 Rome Prize from the American Academy in Rome.

Visual Control of Big Data: Recomputing Visualizations without Aberrant Results

August 20, 2014 10:44 am | by Larry Hardesty, MIT | News | Comments

In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?

Brookhaven theoretical physicist Swagato Mukherjee explains that 'invisible' hadrons are like salt molecules floating around in the hot gas of hadrons, making other particles freeze out at a lower temperature than they would if the 'salt' wasn't there.

Invisible Particles Provide First Indirect Evidence of Strange Baryons

August 20, 2014 10:17 am | by Brookhaven National Laboratory | News | Comments

New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions, but never before observed, are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead make their presence known by lowering the temperature at which other baryons "freeze out"

Scientific Research: New Algorithm Gives Credit Where Credit Is Due

Now, a new algo­rithm devel­oped at Northeastern’s Center for Com­plex Net­work Research helps sheds light on how to prop­erly allo­cate credit.

Creating a realistic computer simulation of how light suffuses a room is crucial not just for animated movies like Toy Story or Cars, but also in industry. Special computing methods should ensure this, but require great effort. Computer scientists from Saarbrücken have developed a novel approach that vastly simplifies and speeds up the whole calculating process.

The first thousand-robot flash mob has assembled at Harvard University. Instead of one highly-complex robot, a “kilo” of robots collaborate, providing a simple platform for the enactment of complex behaviors. Called Kilobots, these extremely simple robots are each just a few centimeters across and stand on three pin-like legs.

When the space shuttle Columbia disintegrated on re-entry in 2002, sophisticated computer models were key to determining what happened. A piece of foam flew off at launch and hit a tile, damaging the leading edge of the shuttle wing and exposing the underlying structure. Temperatures soared to thousands of degrees as Columbia plunged toward Earth at 27 times the speed of sound, said Gallis, who used NASA codes and Icarus for simulations...

Grammatikopoulos simulated two palladium nanoparticles colliding at different temperatures. The hotter the temperature, the more homogenous the resulting product, and the further the atoms in the particle crystallize.

Simulating the Invisible

July 29, 2014 2:07 pm | by Poncie Rutsch, Okinawa Institute of Science and Technology Graduate University (OIST) | News | Comments

Every trillionth of a second, Panagiotis Grammatikopoulos calculates the location of each individual atom in a particle based on where it is and which forces apply. He uses a computer program to make the calculations, and then animates the motion of the atoms using visualization software. The resulting animation illuminates what happens, atom-by-atom, when two nanoparticles collide.

Mutations from Venus, Mutations from Mars: A Sex-difference Approach to Harmful Mutation

July 28, 2014 5:36 pm | by Weizmann Institute of Science | News | Comments

Some 15 percent of adults suffer from fertility problems, many of these due to genetic factors. This is something of a paradox: We might expect such genes, which reduce an individual's ability to reproduce, to disappear from the population. Recent research may have solved the riddle. Not only can it explain the high rates of male fertility problems, it may open new avenues in understanding the causes of genetic diseases and their treatment.

Collecting Just the Right Data: When you can’t collect all you need, new algorithm tells you which to target

July 28, 2014 2:06 pm | by Larry Hardesty, MIT | News | Comments

Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon. But some types of data are harder to collect than online click histories — information about geological formations thousands of feet underground, for instance. And in other applications there may just not be enough time to crunch all the available data.
