Here are some more videos relating to chemistry. Coming from the Vega Science Trust Reflections on Science Series.
Architects of the Microcosmos presented by Sir Harry Kroto
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.
On the Air presented by Michael Garrett
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 dependent on this major raw material. Life-saving operations in hospitals, the purification of polluted rivers and lakes, and superconductivity are but a few fields which require liquefied gas supplies.
