Bits and Pieces: Secrets of a Digital World

Dr James Grime
Thursday, 4 February 2021 - 6:30pm

 

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.
