Bang Goes The Theory – BBC One

bang

Dallas Campbell, Liz Bonnin, Jem Stansfield and Dr Yan Wong take on the scientific world by devising their own ingenious ways of explaining cutting-edge developments in technology.

The first episode tackles gait recognition, vortex rings, genetic engineering and an uncooked egg.

There are already over four million CCTV cameras in the UK. However, British researchers are still investigating even more effective methods of surveillance. Dallas and Liz head to Southampton to find out about a new system of gait recognition that could track each and every one of us, by monitoring the way that we move.

Tackling the science behind the headlines, Liz journeys to meet a US scientist who is developing his own controversial solution to solving the world’s energy crisis. Craig Venter, one of the first people to sequence the human genome, is working to create the first generation of artificial life. Liz grapples with a contentious area of research that raises a raft of ethical questions.

Using the same principles that generate a simple smoke ring, engineer Jem assembles a cannon that he thinks will be strong enough to take on the three little pigs. The cannon produces a vortex shockwave so powerful it can knock down obstacles in its path, including a house of straw and a house of sticks. But will he really be able to succeed where the big, bad wolf failed, and use nothing more than a supersonically generated vortex ring to knock down a house of bricks?

Last but not least, street scientist Dr Yan Wong travels up and down the country to put the nation’s scientific know-how to the test. He asks unsuspecting market shoppers one simple question: how do you cook an egg with a Bunsen burner and a piece of A4 paper?
