Royal Institution Christmas Lectures - Season 8 Episode 4 Simple Signs and Complicated Communications
The fourth lecture in the series, 'Simple Signs and Complicated Communications', is considered lost, as there is no known copy of it. If you do have a copy of the recording, the Royal Institution would love it if you got in touch at xmaslectures@ri.ac.uk to help us make all our CHRISTMAS LECTURES available for future generations.
