Royal Institution Christmas Lectures - Season 49 Episode 1 The Light Bulb Moment
5.10 60 minutes Inspired by fellow Geordie inventor Joseph Swan, Prof Danielle George attempts to play a computer game on the windows of a skyscraper using hundreds of light bulbs.
When Joseph Swan demonstrated the first working light bulb in 1878 he could never have dreamed that in 2014 we’d be surrounded by super-bright LED screens and lights that could be controlled using mobile phones. In this lecture, Danielle will explain how these technologies work and show how they can be adapted to help you realise your own light bulb moments. She’ll show you how to send wireless messages using a barbeque, control a firework display with your laptop and use a torch to browse the internet.
