Royal Institution Christmas Lectures Season 49 Episode release dates & where to watch

1. The Light Bulb Moment

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.

2. Making Contact

Inspired by Alexander Graham Bell, Prof Danielle George attempts to beam a special guest into the theatre via hologram, using the technology found in a mobile phone. When Scottish inventor Alexander Graham Bell demonstrated the first telephone in 1876, he could never have dreamed that in 2014 we’d all be carrying wire-free phones in our pockets and be able to video chat is crystal clear HD across the world. In this lecture, Danielle will explain how these technologies work and show how they can adapted to help keep you connected to the people around you. She’ll show you how to control paintball cannons with a webcam and turn your smartphone into a microscope whilst also investigating a device that allows you to feel invisible objects in mid-air.

3. A New Revolution Finale

Inspired by the Royal Institution’s very own Michael Faraday, Prof Danielle George attempts to use simple motors to construct the world’s greatest robot orchestra. When Michael Faraday demonstrated the first electric motor in 1822, he could never have dreamed that in 2014 we’d be surrounded by mechanical devices capable of performing nearly every human task. In this lecture, Danielle will explain how these robotic and motor-driven appliances work and show how they can adapted to help you kick start a technological revolution. She’ll show you how to turn a washing machine into a wind turbine, how Lego can solve a Rubik’s Cube and how the next Mars rover will traverse an alien world.
