Electrical engineer Professor Danielle George presents the second of this year's
Royal Institution Christmas Lectures. When Alexander Graham Bell demonstrated
the first telephone in 1876, he could never have imagined that wire-free phones
would one day become so universal. In this lecture, Danielle explains how these
technologies work and shows how paintball guns can be controlled with a webcam
and smartphones transformed into a microscope. She also investigates a device
that makes it possible to feel invisible objects in mid-air.
