The Royal Institution Inspiring everyone to think more deeply about science and its place in our lives. The Royal Institution was founded in 1799 and has always been about connecting everyone with the world of science. This could be finding out how science is used in their everyday lives, or exploring the wonders and beauty of science and finding out how interesting it can be. Whenever we talk about science, we don’t just mean chemistry, physics and biology – we mean maths, engineering, computing, technology, medicine and more – all of these are important for all of us, and are also incredibly useful, creative and beautiful topics. We have always put on events and other activities for the public, but we have a long history of scientific research and discovery at the Ri too. Many famous scientists lived and worked over the Ri – 10 chemical elements were first isolated here, 14 scientists connected to the Ri have won Nobel Prizes, and some of the work discovered in the labs in our basement are still very much used today. One example is Michael Faraday’s work on electromagnetism, which forms the basis of every power station worldwide.

Royal Institution activities Online videos & activity resources National education programmes Membership London-based: Talks and shows Holiday workshops Family fun days Faraday Museum Here are some of the things that the Ri does today. We especially have lots going on in London, so if you enjoy your Masterclasses there are a range of holiday workshops at the Ri which you might like to take part in.

The CHRISTMAS LECTURES The CHRISTMAS LECTURES are the Ri’s most famous activity and are televised on the BBC. The first maths lectures by Prof. Sir Christopher Zeeman in 1978 started off the Masterclass programme! Christmas Lecturers include Michael Faraday, David Attenborough, Carl Sagan, Richard Dawkins, Alison Woollard, Saiful Islam & Alice Roberts Begun by Michael Faraday in 1825, the CHRISTMAS LECTURES are now broadcast on UK television every December and have formed part of the British Christmas tradition for generations. The Lectures have been broadcast on TV since 1936 – we think they were the very first science programme on television. The theme changes every year, with the Lectures delivered by an expert in their field. Many world-famous scientists have given the Lectures since 1925, including David Attenborough, Carl Sagan, Richard Dawkins, and our latest Lecturer Sophie Scott. You can watch all of the recent CHRISTMAS LECTURES on our website, along with many of the older ones – and more are going online all the time. Ri members and UK schools can apply for tickets to see them being filmed live – but no adults can attend without someone aged 11-17 accompanying them! To find out more about the Lectures (or Ri Membership) visit our website, www.rigb.org. The first mathematics CHRISTMAS LECTURES were not until 1978, and were delivered by Professor Sir Christopher Zeeman. They were extremely popular and demonstrated all sorts of mathematical concepts, including mathematical proof – some of which you will see in your Masterclasses. In fact, the lectures were so popular that they started off the Masterclass programme and Christopher Zeeman delivered many of the sessions in the first few series of workshops in London. The most recent maths-themed CHRSITMAS LECTURES were delivered by Marcus Du Sautoy in 2006.

Royal Institution videos CHRISTMAS LECTURES – on the Ri website We have a huge video channel on YouTube – if you have five minutes or five hours, there is something to interest you if you like science and maths. We make short videos showing a variety of experiments and the science behind the everyday, animations on interesting topics and we film many of our talks in London. We also have a special series called ExpeRimental which is mainly for parents and carers, or older brothers and sisters, all about doing science experiments at home with their children or younger siblings. As has been mentioned, recent CHRISTMAS LECTURES are available on the Ri website alongside select past Christmas Lectures – more are being digitised all the time. To watch our videos you can search for the Royal Institution on YouTube.  We hope that you will be able to find lots of fascinating things to watch and to help you continue your interest in science and maths once your Masterclass series has finished.
