The Life Scientific Folgen

Annette Karmiloff-Smith, from the Birkbeck Centre for Brain & Cognitive Development in London talks to Jim Al-Khalili about her Life Scientific. Starting out as a simultaneous interpreter for the United Nations she soon decided that not being allowed to express any thoughts of her own wasn't for her. After a chance encounter with Jean Piaget, one of the most renowned psychologists of all time, she decided to pursue psychology and over forty years later she is a world expert in brain development and how babies and children learn. Her research has been cited not just by fellow psychologists, but by philosophers, linguists, educationalists, geneticists and neuroscientists. Her controversial response to guidance issued by the American Academy of Paediatrics, that parents should discourage TV viewing in children under 2, is that if the subject matter is chosen well, and is scientifically based, a TV screen can be better for a baby than a book.

Jim Al-Khalili talks to Robert Mair, professor of Civil engineering at Cambridge University about his life as an engineer in academia and industry and his expertise on finding innovative solutions to the problems of building tunnels under already congested cities.He talks about his innovative technique of 'compensation grouting' which prevented Big Ben from tilting and even cracking and coming away from the Houses of Parliament during Jubilee line extension. Crossrail is one of the biggest engineering projects in Europe and involves constructing 26 miles of new tunnels underneath London's busy streets and under the existing tube network. Robert talks the latest tunnelling technology being used and the huge drilling machines with names like 'Ada' and Phyliss' which use high pressure to minimise ground movements as they drill and even have a kitchen and bathroom facilities on board. He also talks about his latest work on how smart sensors which can harvest their own energy. And when built into buildings, roads, tunnels they could make sure the engineering projects of the future will be able to continuously monitor and report on their own safety.

Jim Al-Khalili talks to Amoret Whitaker, an entomologist at the Natural History Museum in London. Her intricate understanding of the life cycles of the flies, beetles and the other insects' which feed on decomposing bodies means she is regularly called by the Police to the scene of a crime or a murder investigation. There she collects and analyses any insect evidence to help them pin point the most likely time of death. In some instances, this can be accurate to within hours.She is just one of only a handful of forensic entomologists working in the UK. She talks to Jim about her life as a research scientist, breeding flies in the far flung towers of the Natural History Museum and her work as a forensic expert with police services across the country. Dropping her work at a moment's notice she can be called any time of day to anywhere in the country to attend a crime scene. She also talks about her regular trips to a research facility at the 'Body Farm' at the University of Tennesee in Knoxville in Ameria to get a better understanding of how real human bodies decompose. Her passion is insects and while our instinctive reaction to flies and maggots may be one of revulsion - when you take time look at them properly, and in detail, she says you can see what truly incredible creatures they are.
