Bits and Pieces: Secrets of a Digital World
Every message we send on the internet is transmitted in code. Like a kind of Morse code, these invisible messages surround us. But with so many messages being sent simultaneously, we need maths to transmit those messages reliably and without mistakes.
The solutions to these problems have some unlikely origins, including one Golden Age Hollywood actress and a World War II code machine that was even more difficult than the famous Enigma. Yet these ideas are used today to transmit messages from space or to play a CD even when scratched.
Join mathematician James Grime as we take a look at the hidden maths behind the digital world, from WWII to WiFi.
About the speaker
Dr James Grime is a mathematician and public speaker. James studied the mathematics symmetry, known as Group Theory, at the University of York. After leaving York, James worked at the Millennium Mathematics Project at the University of Cambridge, and travelled the world giving public talks on the history and mathematics of codes and code breaking. James currently works with MathsWorldUK, an organisation dedicated to creating the UK’s first national mathematics discovery centre. James can also be found talking about interesting maths on the YouTube channel Numberphile, which now has over 3 million subscribers.
