Queen Mary College, University of London
Peter Kalmus is Emeritus Professor of Physics at Queen Mary, University of London, UK. He has carried out research in particle physics at accelerators in the UK, USA, Germany and CERN, and is an author of 230 research publications. He was awarded the Rutherford Medal for his contribution to the discovery of the W and Z particles which showed that electromagnetism and the weak interaction were aspects of the same force. He was also awarded the Kelvin Medal for public understanding of physics, and an OBE from the Queen for services to physics.

AntiMatter - Monday 17th March 2005
What is antimatter and where might it exist? For every type of particle there is a corresponding antiparticle. The electric and nuclear forces between two antiparticles are the same as between corresponding particles. Thus antiatoms and even antimatter in bulk might exist. However when antiparticles come into contact with ordinary particles they can annihilate each other, so antimatter would not exist for long on Earth unless it was totally isolated. We explain how particle physics could help us to avoid being annihilated by a science-fiction antimatter alien from another world. We review searches for antimatter in the universe, and describe some experiments with antiparticles on Earth.

Particles and the Universe
One of the outstanding achievements of 20th Century science was the realisation that the great diversity of nature is based on a handful of elementary particles acting under the influence of only a few fundamental forces. It forms the basis of particle physics, a field which extends beyond the confines of the atom towards a synthesis with astronomy and cosmology. We explain particle physics and show how experiments at large accelerators help us to recreate some of the conditions of the early universe.
