Glueballs are made out of gluons. They are in principle allowed by the QCD theory (the most important theory for nuclear physics), but there is no experimental evidence for them. There have been many experiments, which have tried to find them, but so far there has been no confirmed signal for glueballs. Better experiments and more accurate theoretical calculations of the glueball masses may help us find this new class of particle.
Plymouth is known as the Ocean city. The sea permeates almost every aspect of the city, including the University of course. It is important to understand the sea’s influence on the coast (as anyone who has taken the train from Plymouth to Exeter can testify). What better way to understand the sea, than to use mathematics.
On April 11th, the extensively revised second edition of the book Modelling Coastal and Marine Processes, written by Prof. Philip Dyke will be published. The update now includes pointers to open source software, and details developments in new numerical methods, beyond the trusty finite difference methods.
We were recently sent an online magazine about mathematics called Chalkdust. The magazine seems largely written by students at UCL. Some of the articles we liked were:
An article about using analog computers to solve differential equations. When I worked at the National Nuclear Corporation, during the summer vacation, when I was an undergraduate student, one of the staff members kept complaining that the analog computers they use to use to simulate nuclear reactors were much better than the digital computers.
