How to manage motorway tolls through the Game Theory
A team led by José Manuel Zarzuelo, Professor of Applied Economics, has applied the co-operative Game Theory to calculating motorway toll charges. The results of the study have been published in the specialised journal European Jo ...
Kenneth Appel dies, used computer on map question
Kenneth Appel, a mathematician who was the first to use a computer to prove a century-old major mathematical theorem, has died at age 80 in Dover, N.H.
The problem with predictions: Speaker says peering into future remains an imperfect science
People have always yearned to see into the future, to peek around the corner and make sense of what's going on, according to author and mathematician David Orrell. But predicting the future is difficult. ...
The RSA algorithm (or how to send private love letters)
A couple of days ago on The Conversation, I set myself up with a task: to defend the usefulness of so-called "useless" maths. Today, that defence continues, with a look at the RSA algorithm.
Your number's up: A case for the usefulness of useless maths
I once made the mistake of asking a mathematician why he devoted his whole life to maths. "Because it's fun!" he replied wildly, his flabby cheeks beaming with childlike excitement.

Organic electronics—a hot matter
Organic semi-conductors could revolutionise electronics in various areas. Nowadays, components put out such high performances that they are used in small devices like mobile phones. With larger devices, however, ...

Cutting through the spin on supermassive black holes
Astronomers have measured the spin of a black hole buried in the heart of a galaxy located 56 million light years away, and discovered it was spinning quickly – about as quickly as it could go. That was t ...
Fermat's Last Theorem, more can be proved more simply: Professor steers field toward a numbers-only proof
Fermat's Last Theorem—the idea that a certain simple equation had no solutions— went unsolved for nearly 350 years until Oxford mathematician Andrew Wiles created a proof in 1995. Now, Case Western Reserve University's ...
New research improves estimates of amount of ash in volcanic clouds
(Phys.org)—The amount of ash released by Iceland's Eyjafjallajökull volcano during April 2010 was significantly underestimated at the time of the eruption, according to a new model developed at the University ...
University professor discovers largest prime number to date
(Phys.org)—Curtis Cooper, professor of math and computer science at the University of Central Missouri, has discovered the largest prime number to date, it's 257,885,161 – 1. It has 17 million digits and is also a Mersenne prime (a prime number defined by the equation N=2n-1, ...
