Perfume, passenger jets, petrol pumps, Swiss Army knives - things many people use daily, and most take for granted. Comedian Robert Llewellyn takes a closer look at some of the marvels of today's technology, focusing on the science that make it work. The mysteries of satellite navigation? He's on it. How do a billion transistors fit on a tiny microchip? He looks into that as well, along with dozens of other everyday items and events, from shuttle launches and halogen bulbs to windscreen wipers and printing cash.
