This very early series of  Vega science videos feature Helen Sharman on Life in Space, Chris Freeman on Bernal,  John Murrell on States of Matter and John Maynard-Smith on Flight and was originally broadcast on the BBC2 Learning Zone.  The Masterclasses reveal these scientists personal views on key concepts and achievements as well as their approach to scientific method.  In this way we see how science advances our understanding of how nature and the physical world work as well as what science can do.
