The Royal Institution Christmas Lectures are a series of lectures on a single topic, which have been held at the Royal Institution in London each year since 1825, except several years during the Second World War. The lectures present scientific subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday initiated the first Christmas Lecture series in 1825, at a time when organised education for young people was scarce.This series of lectures is still interesting for its basic explanation of sound and hearing, and the history of the research into it.
