Press Release prepared for BAAS meeting in Plymouth August 1991

BUBBLES, QUARKS AND EXPLODING STARS:

PHYSICS AT SCIENCE 91

The world around us is governed by natural laws. Understanding how the world works is the universal role of physics. It is an exciting and challenging subject which also has many useful applications and can help to improve our lives. Some of the great variety and scope of the subject will be presented during SCIENCE 91 in a stimulating and entertaining programme aimed at the non-specialist. There should be something for the most lay layman, for the distinguished professor, for the young and the not so young.

This variety is very evident on Tuesday, the first full day. We start the morning with a talk on "Soap bubbles" by Dr Cyril Isenberg, a speaker well known to school and other audiences. All of us have blown soap bubbles, but perhaps we don't realise that research on bubbles and films is still being conducted by various scientists. Dr. Bill Vennart in "Looking inside the body" will describe how, by using physics techniques, doctors can examine our organs non-invasively, in other words without damaging or hurting us. Dr. Pedro Waloschek's talk "Quark jigsaws" will show, using very simple ideas, that everything in the universe is constructed from just a few building blocks.

The theme is reinforced in the afternoon when the Physics President, Professor Peter Kalmus in "The forces of nature". will talk about gravity and the other fundamental forces. Up till recently it was assumed that there were four (perhaps even five?) distinct forces which are responsible for all the phenomena in the world, but recent experiments have shown that these have been reduced to three. After tea there are talks by Professor Keith Runcorn and Dr. David Edwards about the famous physicist Sir James Chadwick, the discoverer of the neutron, who was born just 100 years ago.

Physics can be beautiful as well as interesting. Come and see the "Beauty of Physics" photographic exhibition and the launch of the 1991 Competition for new photos, and find out how you might win a prize. At 5 pm come to the Physics and Mathematics Mixer, where over a glass of wine the young and old can mix, talk to each other, and meet the speakers.

The Wednesday programme is a complete contrast. There will be a session cutting right across the various sciences. "From Particles to People" is a scientific history of the world. Starting with the Big Bang — the creation of the universe, we finally get to Man, in six easy lectures by distinguished speakers covering physics, cosmology, astronomy, geology, chemistry and biology. Professor Martin Rees kicks off followed by Professor Michael Rowan-Robinson. They will take us from the first microsecond of the universe, or even earlier, to the formation of galaxies and the creation of the chemical elements. Professor Keith Runcorn will then cover the Earth's evolution, from its accretion in the early solar system to the present time.

Carbon plays an essential role in chemistry, and particularly the chemistry of life. Recently quite new forms of carbon, shaped like footballs, have been found and have completely changed our understanding of how microparticles can be formed on Earth and in astronomical sites. This will be described in the afternoon by the discoverer, Professor Harry Kroto. This then leads to biology, where the possible nature of first living organisms are discussed by Dr. Graham Cairns-Smith, and the final talk by Professor Lewis Wolpert takes us the final step from cells to embryos and man.

Thursday morning is devoted to super science. Superconductors have fascinating properties, not only the ability to carry currents for ever without resistance. Recently this work has moved from the ultracold to less extreme temperatures, and this will be described by Dr. Bill David. The news of the supernova, an exploding star in our neighbouring galaxy, reached the Earth in 1987. Dr. Paul Murdin will show that we have learned a lot of physics and astronomy from this one event. At the end of the morning, in "Superstrings", Professor Michael Green will show how this branch of physics may play a key role in unifying all the physical forces and elementary particles as well as elucidating the structure of space and time. In complete contrast, in the afternoon Dr. Mike Gluyas will give his highly popular lecture "Musical Squares" — with many audio-visual demonstrations. This talk has been seen by tens of thousands of school pupils, and is recommended for people aged 8 to 80. There is also a session showing that optics can improve the quality of life in a variety of ways — in communications, medicine, opthalmology and many other areas.

On Friday morning, Kate Bellingham of BBC TV's "Tomorrow's World" will introduce a session on "Developing the World with Physics" a session organised by the Institute of Physics Public Affairs Department. Drs Bob Fox, Andrew Brown and Bruce King will show how physics research can help the global effort needed for the developing world to confront its major problems. The topics include unlocking natural and human resources, producing cheap water power and using space technology to predict droughts and assess renewable resources.

This full and varied programme had to be planned some months ago. However we were able to slip in at short notice a topic which has caused some controversy in national science planning. At the beginning of this year, the Science and Engineering Research Council decided that it will close its Nuclear Structure Facility at Daresbury in order to save money. This was at a time when significant discoveries had just been made there. Professor John Sharpey-Schafer's talk on "Spinning nuclei into exotic shapes" will describe this work on Monday afternoon at 2 pm.

All week there will be an exhibition from CERN the European Laboratory for Particle Physics. This highly professional display will show that in order to study the smallest things in the universe we require the largest equipment including a particle accelerator which is 17 miles in circumference. This is achieved in a remarkable laboratory, supported by 16 European countries including the UK, which physically crosses the international border between Switzerland and France, and which is used by many UK groups of researchers.

If you are interested, pick up a yellow Physics Programme at the SCIENCE 91 Office. This will list all the topics and speakers and give the times and locations of all physics events. You will find that physics can be fun and is not difficult.

Peter I. P. Kalmus President of the Physics Section at SCIENCE 91.

The Author of this article is

Professor Peter I. P. Kalmus

President of the Physics Section at SCIENCE 91.

Professor of Physics at Queen Mary and Westfield College, University of London. He has carried out research in elementary particle physics using accelerators in the USA, the UK, Germany and at CERN. He is author or coauthor of about 150 scientific papers, and in 1988 was awarded the Rutherford Medal and Prize for his contributions to the discovery of the W and Z particles, a discovery which showed that there were only 3, not 4, fundamental forces in nature.
