But predicting the future is difficult. And what's more, the search for the "perfect model" of prediction often reveals as much about people's sense of aesthetics as it does about the future, Orrell said last Thursday during "Perfect Model: The Past, Present, and Future of Prediction," a talk sponsored by the Peabody Museum of Archaeology and Ethnology.

José Latorre and Germán Sierra describe in their paper they've uploaded to the preprint server arXiv, their formula that uses spin states of quantum bits (qubits) to calculate the number of prime numbers below a given value.

That was the big news, based on a paper in Nature, in recent days.

Now, Case Western Reserve University's Colin McLarty has shown the theorem can be proved more simply.

This could have important consequences for airspace management during future eruptions.

It has 17 million digits and is also a Mersenne prime (a prime number defined by the equation N=2n-1, where N and n are both prime numbers). The find was part of the Great Internet Mersenne Prime Search (GIMPS) project that uses a distributed approach to number crunching using volunteer computers.

From humble and obscure beginnings, he blossomed into one of the greatest mathematical geniuses of all time. Largely self-taught and cut off from much of the current mathematical work of his time, he nevertheless produced observations and results that continue to dazzle.

Some researchers from the University of Rochester in collaboration with a University of California, Berkeley, mathematician/crowdsourcing entrepreneur, have come up with a killer personal assistant approach. "We introduce Chorus, a system that enables realtime, two-way natural language conversation between an end user and a crowd acting as a single agent." So begins their paper, "Speaking with the Crowd," suggesting the ideal artificial chat partner is the partner that is actually the work of contributions from many crowdsourced workers. The researchers propose a crowd-powered chat system that behaves as an online collaborative interface. They believe it one-ups existing systems because it can take on more complex tasks.

TechnologyMon, 10 Sep 2012 19:30:01 EDTnews266520439Dutch research set to make electricity grids future-proofThe rise of renewable energy calls for smart electricity networks (smart grids) that can align energy supply and demand. Researchers at the Centre for Telematics and Information Technology (CTIT) at the University of Twente have developed an ICT-based management and control methodology that is able to do exactly this. Research carried out by mathematician Maurice Bosman shows that this method is effective and capable of making existing electricity grids future-proof. Bosman defended his thesis on 5 July at the Faculty of Electrical Engineering, Mathematics and Computer Science.

At those sizes, three-dimensional (3-D) structures are too small to be assembled by any machine and they must be guided to assemble on their own. And now, interdisciplinary research by engineers at Johns Hopkins University in Baltimore, Md., and mathematicians at Brown University in Providence, R.I., has led to a breakthrough showing that higher order polyhedra can indeed fold up and assemble themselves.

The San Francisco Giants, Milwaukee Brewers and Florida Marlins could be close on the heels of the Reds and Braves but should miss out on the post-season by 3 or 4 wins. For more than a decade, Bukiet, an associate professor and associate dean, has applied mathematical analysis to compute the number of regular season games each Major League Baseball team should win. Though his expertise is in mathematical modeling, rather than baseball, his projections have compared well with those of so-called experts over the years.

This classic method -- define a problem, test a proposed solution, learn from failure and try again -- is the main route by which scientists discover new biomaterials and drugs today. This approach is also used to design ways of manufacturing these new materials, but the process is immensely time-consuming, producing a successful therapeutic product and its manufacturing process only after years of experiments, at considerable expense.

Questions regarding the dynamics of standing water waves have gone unanswered for decades since numerical simulations have not been powerful enough to explore wave behavior with sufficient accuracy. In the new study published in Physical Review Letters, Wilkening has used numerical simulations with a sufficiently high resolution (capable of achieving 26 digits of accuracy) to help better understand the dynamics that occur at the crests of standing water waves.
