At the end of 2011 the Royal Institution launched the Ri channel, a website giving on-demand access to the very best science videos from the Ri and around the web. Alongside highlights from recent Ri events, including the Christmas Lectures, the Channel features re-digitised footage from the Ri archive and a range of high-quality videos from filmmakers and scientific institutions across the UK and beyond. New videos are added regularly. The collection is now organised under four categories: Biology,Chemistry,Mathematics and Physics. There is also an Interactive Games section which offers a wide range of educational games and quizzes to learn more about science, engineering and the natural world.
