Michael Garrett discusses the physical properties of gases and demonstrates how air is liquefied. Liquefied gases are a key resource for survival with an amazing range of applications and there are now few industries which are not in some way depende....

With his innate ability to explain the most abstract and complex concepts of modern physics in accessible terms David Miller convinces even the most sceptical that 'empty space' is teeming with a new cast of fundamental characters from virtual photon....

In thistalk Harry Kroto explains that molecules have structures that are every bit as real in the mind of the chemists who create them, as are the edifices of brick, steel and concrete designed by architects and built by engineers.

Satellite, ship survey and computer modelling studies of the workings of the marine environment are used explore present fish supplies worldwide. The desperate need for global 'farming' strategies necessary to ensure that the Oceans can continue to p....

The controlled ways that electricity and magnetism can stimulate the body are demonstrated and how the resulting responses can aid diagnosis discussed.

An elegantly simple optical diffraction demonstration with an inexpensive laser pointer is used to show the way in which x-rays can reveal the structure of crystals, and in particular, the double helix structure of DNA.

The concept of creativity from the point of view of how original ideas develop is explored with the aid of recent advances in computer modelling programming strategies. Featuring some beautiful examples, Margaret addresses the question, can computers....

Nobel Laureate Professor Sir John Cornforth, overcomes his deafness to present an elegant account of how he, and his wife Rita, disentangled a historically important puzzle in steroid synthesis.

Helen Sharman, the UK's first astronaut, gives a vibrant account of her personal experience of life in space using models and film to illustrate the key scientific concepts involved in spaceflight. Among other things she discusses the way Newton's Th....

John Maynard Smith, one of our most eminent evolutionary biologists and scientific communicators originally trained as an engineer and spent the war years designing aircraft. He describes the way that flight developed in the animal kingdom. The fossi....

John Murrell discusses the basic physical principles relating to the gaseous, liquid and solid states with the aid of models and demonstrations. Attention is drawn to phase changes and subtle features involving intermediate phases such as liquid crys....

Chris Freeman, the founder and first director of the UK's Science Policy Research Unit introduces Bernal, the father of the protein crystallography techniques which enabled the double helix structure of DNA to be unravelled. Bernal's major impact on ....
