The Life Scientific Folgen

Andrea Sella is a science showman, whose theatrical demonstrations of chemistry are filling theatres up and down the country. But as Professor of Materials and Inorganic Chemistry, Jim Al-Khalili asks him if he would rather be known for his research into rare metals than for his whizz bang displays.

Richard Dawkins' first book on evolutionary biology "The Selfish Gene" was published to much acclaim and some controversy in 1976. In this interview with Jim Al-Khalili, Professor Dawkins discusses his enthusiasm for the science that inspired the book and how he popularised the idea of the immortal gene. Using the source material from scientists such as Bill Hamilton, Robert Trivers and John Maynard Smith, he presented a gene's eye view of the world. He's written many other books on evolutionary biology, such as "The Extended Phenotype" "Unweaving the Rainbow" and "The Ancestors Tale". In 2006 he published a polemic which he describes as "a gentlemanly attack on religion", "The God Delusion". Jim asks what he hoped to achieve by writing the book and finds out why he would rather be known for his science than his atheism.

A world in which planes are silent may sound like a pipe dream; but University of Cambridge engineer, Dame Ann Dowling, and her team proved it is possible to build an aircraft that barely makes any noise. A brilliant mathematician and a keen pilot, Ann now heads of one of the largest engineering departments in Europe. Her design for a silent aircraft could improve the quality of life for millions of people living near airports worldwide: so does she mind that it never got off the ground? Jim talks to Ann Dowling about mathematics, engines and how she always wanted to do something useful. Producer: Anna Buckley.
