[email protected] mission culture scientifique et technique http://metaxy.uni.lu LES JEUDIS DES SCIENCES COLLOQUIUM GENERALE LEÇON 182 SEMESTRE XXIV Cool Science: demonstrations of what you can do with liquid nitrogen Ted Forgan University of Birmingham 30.05.2013 17:30 Auditoire B02 Campus Kirchberg Many things behave quite differently when you cool them towards absolute zero: rubber is no longer rubbery, air becomes liquid and some metals lose all trace of electrical resistance, so that electric currents can show “perpetual motion”. Ted Forgan, who has spent his career researching superconductors and low temperature physics, will present a lecture-demonstration of these effects. He will explain why superconductivity is a wonderful example of the effects of quantum mechanics – the wavelike properties of particles – but in large-scale objects that you can see, instead of inside atoms. Ted Forgan has been based in Birmingham UK for all his scientific career, but since 1984 has spent much time at large international facilities using neutrons, muons and X-rays to investigate superconducting and magnetic materials, and more recently the alignment of biological materials in high magnetic fields. He combines this fundamental research with an enthusiastic lecturing style to explain the mysteries of the quantum world that appear when things are cooled to low temperatures. His achievements in the study of flux lines in superconductors were recognised by the award of the 2004 Mott Medal and Prize from the UK Institute of Physics.
