The origin of the CHRISTMAS LECTURES

The first series was delivered in December 1825 by the Royal Institution's Professor of Mechanics, John Millington. Two years later Michael Faraday gave his first of nineteen series of lectures, culminating with his 1860/61 series 'The chemical history of a candle' which produced perhaps the most popular science book ever published. As the Royal Institution's flagship lecture series, it was an obvious candidate for broadcasting by the BBC's fledging television service in 1936. In the post-1945 period several lectures were televised, but it was not until the 1966/7 series that they started being broadcast annually.

Where do I come from?

What makes me human?

What makes me, me?

2017 Sophie Scott: The language of life

In the 2017 CHRISTMAS LECTURES, Sophie Scott explores how laughter provides a link to our animal past, how our voice box has changed the shape of our faces, and why we sound the way we do. She also uncovers the hidden code of communication, the most secret and sometimes more sinister side of human interaction - everything we say without opening our mouths - from contagious behaviours to the emotional clues in smell, and whether information wired directly into our brains is really a future we want. 

Say it with sound

Silent messages

2016 Saiful Islam: Supercharged: Fuelling the future

The 2016 CHRISTMAS LECTURES describe something invisible that drives everything around us, from our bodies to mobile phones, from aeroplanes to all the stars in the universe: energy. In each lecture, Saiful Islam faces a big question - what is energy and where does it come from? How can we best make use of it? and How can we store energy to use later on? Along the way we learn about the energy that power our homes, the energy that powers our cars and see how the most important machine of them all, the human body, compares to all the gadgets we carry around with us.

The 2013 CHRISTMAS LECTURES, presented by Alison Woollard from the University of Oxford, will explore the frontiers of developmental biology and uncover the remarkable transformation of a single cell into a complex organism. What do these mechanisms tell us about the relationships between all creatures on Earth? And can we harness this knowledge to improve or even extend our own lives? 

Where do I come from?

Am I a mutant?

Could I live forever?

2012 Peter Wothers: The modern alchemist

Wheh medieval alchemists staged spectacular stunts in front of royalty they never revealed the secrets of their mystical potions and fire-breathing creations. Today's chemists can perform equally impressive feats, but they do so to explain and explore the extreme frontiers of our material world. Watch Peter Wothers, the modern alchemist, as he unpicks the chemistry of the world around us - looking at air, water and earth - three of the original ancient Greek 'elements' that tantalised alchemists for centuries. 

Air: The elixir of life

Water: The fountain of youth

Earth: The philosopher's stone

2011 Bruce Hood: Meet your brain

In the 2011 CHRISTMAS LECTURES, Bruce Hood explores what we know about how our brains work, and how these remarkable organs make us truly human. He looks at how you create your own version of reality, what makes your brain decide which information to trust and which to ignore (without you even knowing) and why you are programmed to read other people's minds. 

What's in your head?

Who's in charge here anyway?

Are you thinking what I'm thinking?

2010 Mark Miodownik: Size matters

Beginning his journey into the world of scale with a furry friend, Mark Miodownik reveals why hamsters fare better than humans when jumping from the top of a skyscraper. We find out why mountains don't grow any taller, why the size of an elephant means it has trouble dancing, and why ants can lift many times their own body weight.

1992 Charles J. M. Stirling: Our world through the looking glass

We are set apart from other animals both by use of language whose control is normally located in the left side of the brain and by the fact that unlike most other animals, which have mix handedness, we are predominantly right-handed. In the 1992 CHRISTMAS LECTURES, we look at first our own symmetry, overall in terms of handedness and our superficial appearance, and also below the surface at ours brains and other organs. Then we shall look at ourselves in the world at large, focusing on the symmetry of our fellow creatures and the artefacts that we have created. The connection of both of these to left-right relationships will be explored.

1985 John David Pye: Communicating

People communicate all the time. A lecture is one special kind of communication, but we communicate with each other in a wide variety of different ways, for otherwise life itself would be impossible. The basic principles are really quite simple but the details are endless and fascinating. We will explore together the fundamental 'rules of the game' of communicating and use them to examine a wide range of different examples.

1984 Walter Bodmer: The message of the genes

New developments in genetics have made it possible to study the chemistry of the genes to an extent that could hardly even have been imagined previously. Now we are beginning to see what it might be that turns a normal cell into a cancer cell, and why the body sometimes attacks itself to produce diseases such as diabetes in children or rheumatoid arthritis. When will the new genetics tell us why, or whether, one person may become a gifted painter, another a musician, another an athlete and another a mathematician? How far can we go in explaining the infinite variety of mankind?

1983 Leonard Maunder: Machines in motion

The 1983 CHRISTMAS LECTURES discuss the ways in which our knowledge of motion continues to grow. We shall also explore how it is being used to extend the extraordinary variety of machines created for our use and convenience. In the future as in the past, it will be the task of the engineer to discover new ways of doing things and to invent, design and make the new machines. All our experience suggests there are exciting prospects ahead that as yet we can hardly imagine.

1981 Reginald Victor Jones: From Magna Carta to microchip

The CHRISTMAS LECTURES at the Royal Institution started in 1826, and there have now been more than one hundred and fifty in the series; and yet none has previously been on the theme of this year's lectures, which is measurement. Perhaps this is because the measurement is so much part of human life that we tend to take it for granted; but if we are to understand how our modern world, with all its achievements and its dangers, has evolved, then we need to know what measurement is, the principles by which measurements can be made, and why their applications have been of so much importance in the advance of science and in the development of technology

Principles, standards and methods 

The measurement of time

More and more about less and less

Outwards to the stars

Some impacts of measurement on life: And can we take it too far?

1980 David Chilton Phillips: The chicken, the egg and the molecules

The 1980 CHRISTMAS LECTURES, five presented by David Phillips and one with Max Perutz, showcase the complexity and importance of the proteins that make up so much of life. The lectures weave through the DNA helix, unravelling the mechanism that links DNA and protein production, and asking 'which came first, the DNA or the protein?'.

1979 Eric M. Rogers: Atoms for engineering minds: a circus of experiments

When one learns what has been discovered about atoms one has to learn by hearsay, one has to accept the indirect methods and swallow the picturing by imaginative models. Then a keen listener must long for some experimental support or illustrations. That is what these lectures will offer in their 'circus of experiments'. The circus cannot cover all our new knowledge of atoms but it will, we trust, give visitors a feeling of friendly first-hand acquaintance, a contribution of confidence and understanding as well as a delight in seeing experiments

1978 Erik Christopher Zeeman: Mathematics into pictures

These were the first CHRISTMAS LECTURES in its then 149-year history to be presented on the subject of mathematics and the series is still lauded as inspiring a new generation of mathematicians. Amongst the live audience was a budding young mathematician called Marcus du Sautoy who went on to present the Lectures in 2006 entitled 'The num8er my5teries'. Furthermore, the enthusiasm generated by the series led Professor Zeeman to establish the Ri’s Mathematics Masterclasses programme in 1981. They continue to enable thousands of young people across the UK to participate in the hands-on and inspired learning that is the hallmark of the CHRISTMAS LECTURES.

1972 Geoffrey G. Gouriet: Ripples in the ether: the science of radio communication

In his 1972 CHRISTMAS LECTURES, Geoffrey G Gouriet explores the past, present and future of radio communications, and the science that lies behind it. Radio waves are all around us, continuously being produced and received through man-made devices enabling us to connect with each other and communicate information. Geoffrey Gouriet, through the course of six Lectures, takes us on a journey through history from the first telephone to the 'Viewphone' and with the aid of exciting demonstrations, he explains how devices in our house like the TV translate broadcasted signals into moving pictures.
