What is information?

Met computers kun je informatie opslaan en versturen, maar wat is informatie eigenlijk? Hoeveel informatie staat er in een boek van 100 pagina's? En welke boekenserie bevat meer informatie: “De wereld van Darren Shan” of “De griezelbus van Paul van Loon”? Hoe meet je dat?

Computers are used to store and send information, but what is information anyway? How much information does a book of 100 pages contains? What book series contain more information: “The Saga of Darren Shan” or “The Horror Bus of Paul van Loon”? How to measure this?

This lecture for the Museum Jeugduniversiteit for children aged 8 to 12 is based on the wonderful Computer Science Unplugged activities by Tim Bell, Ian Witten and Mike Fellows. In the lecture I explain the theories of Claude Shannon, talk about statistical language models, and we play the Twenty Guesses quiz.
