[more]Wikipedia wrote: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, missing 1939-42 due to 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. This came at a time when organised education for young people was scarce. Faraday presented a total of nineteen series in all.
