The Sound of Saturn: The Winds of Titan, from the Huygens Probe
 
03:14
The actual sound recording from the Huygens Probe as it descends through the methane atmospheres of Titan, to land on the surface of this moon of Saturn. This is the sound of the landing on another body in our solar system most distant from the earth. Professor Carolin Crawford, Gresham Professor of Astronomy, introduces the recording, describing the 2 1/2 hour descent through the methane winds blowing at 6 to 7 km per hour. She then goes on to explain why we haven't yet been able to hear the sound of the atmosphere of Mars, and how we might be able to soon. This is an extract from a free public lecture by Carolin Crawford, Gresham Professor of Astronomy: 'The Sounds of the Universe'.

Are Averages Typical? - Professor Raymond Flood
 
59:44
Not necessarily, for example the average person has fewer than two legs! This is because some people have fewer than two legs but nobody has more than two, so dividing the total number of legs by the total number of people to get the average gives a number less than two. Average does not mean typical! The lecture will examine how the work in the 19th century of such mathematicians as Florence Nightingale, Adolphe Queteller and Karl Pearson on describing and quantifying variation and uncertainty laid the foundations for the theory of statistics as a mathematical discipline.

Small-World Networks: "Six-degrees of separation" - John D Barrow Gresham College maths lecture
 
09:05
"Stanley Milgram's other experiment" was a brilliant investigation of 'small world' networks and it initiated the idea of 'six degrees of separation'. He sent 400 letters to random people across America to see how many steps they would then need to take before they got to a particular stockborker in Boston. In this extract from his lecture on 'Codebreaking in Everyday Life', John D. Barrow, Gresham Professor of Geometry and Professor of Mathematical Science at the University of Cambridge, explains this piece of mathematics that we find in our everyday lives. This is the 4th part of 'Codebreaking in Everday Life'.

Enoch Powell and the Sovereignty of Parliament - Professor Vernon Bogdanor
 
01:10:32
Enoch Powell was the most powerful postwar exponent of the idea of the sovereignty of Parliament and indeed of English nationalism, opposing the coming of a multiracial society, devolution, and entry into the Common Market, as the European Union used to be called. His ideas proved unacceptable not only to Labour but also to the Conservative Party which he left in 1974. Was he, as his supporters allege, a prophet before his time; or have developments since his death shown that his fears were groundless? This is a part of the lecture series, Making the Weather: Six politicians who shaped our age. Winston Churchill wrote of Joseph Chamberlain, Colonial Secretary at the beginning of the 20th century, that, even though he never became Prime Minister, he 'made the weather', meaning that he played a crucial role in shaping the political agenda of his day. These lectures discuss six postwar politicians, none of whom became Prime Minister, but who, like Joseph Chamberlain, also made the weather and so helped to shape the age in which we live.

From Gold to Paper and Back Again - Professor Jagjit Chadha
 
57:59
Starting his series on the history and science of monetary policy, Jagjit Chadha examines the gold standard: http://www.gresham.ac.uk/lectures-and-events/from-gold-to-paper-and-back-again Money was linked historically to the value of commodities such as gold in order to help preserve its value and encourage its wide and ongoing use. There are many examples of countries temporarily delinking from commodity standards. This lecture will explore the consequences of tying monetary value to commodities and why there are better choices for a government than a commodity standard.

Summit Diplomacy: Some Lessons from History for 21st Century Leaders - Professor Paul Reynolds
 
09:37
'It is not easy to see how matters could be worsened by a parley at the summit.' Winston Churchill coined the term 'summit' in 1950, during some of the darkest days of the Cold War. In the second half of the twentieth century summit meetings became a central element of international diplomacy -- among them dramatic encounters such as Kennedy and Khrushchev at Vienna in 1961 and Reagan and Gorbachev in Reykjavik in 1986. Today summits are in the headlines all the time -- for meetings of the EU, G8 and G20 -- and the word is often used in other walks of life, especially in business. But there is relatively little reflection about what summit meetings are supposed to achieve or about their costs as well as benefits. We need to take a long view of summitry, exploring why, for most of history, leaders deliberately avoided face-to-face meetings. We should look more closely at some of the classic Cold War meetings, asking why some worked and others did not. And we also need to understand how summitry has changed since the Cold War. 'Lessons' from the past are always tentative but this lecture suggests what twenty-first century statesmen might learn from history, if they have the time and inclination.

How Can Software Be So Hard? - Professor Martyn Thomas CBE

The General Election of 2010 - Professor Vernon Bogdanor
 
59:03
The best and clearest breakdown of the important factors in the 2010 election: http://www.gresham.ac.uk/lectures-and-events/the-general-election-2010 The 2010 election led to the first peacetime coalition government in Britain since 1931. It occurred in the midst of a financial crisis, with Britain facing a large budgetary deficit, necessitating a period of austerity. So difficult was Britain's economic position that Mervyn King, the Governor of the Bank of England, declared that 2010 was an election which any rational party would wish to lose.

Agincourt or Azincourt? Victory, Defeat and the War of 1415 - Dr Helen Castor
 
44:16
In the year of the battle's 600th anniversary, Agincourt remains one of the most resonant names in the roll-call of English military history: http://www.gresham.ac.uk/lectures-and-events/agincourt-or-azincourt-victory-defeat-and-the-war-of-1415 Thanks to Shakespeare, the triumphant tale is embedded in our national psyche: the astonishing victory against overwhelming odds of Henry V's 'happy few' over the flower of French chivalry. But if we cry God for Harry, England and St George, we tell only half the story. What of those who cried God for Charles, France and St Denis? The battle is set in its fifteenth-century context - when the outcome of military conflict was understood as the result of God's will - and unravels the implications of two contrasting narratives: English victory at Agincourt, and French defeat on the field they knew as Azincourt. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/agincourt-or-azincourt-victory-defeat-and-the-war-of-1415 Gresham College has been giving free public lectures since 1597.

The Expanding Universe - Professor Joseph Silk
 
54:06
Professor Joseph Silk FRS embarks on an illustrious journey through the universe to explain the paradigm shift in todays scientific view on the physical expansion of space http://www.gresham.ac.uk/lectures-and-events/the-expanding-universe It was once inconceivable that the universe could be expanding. The static universe survived three thousand years of analysis and observation, to become enshrined as a cosmological solution to the equations of Einsteins theory of general relativity. Only after three decades into the twentieth century did a paradigm shift occur. This was based on observational data, but it was to take decades before the recession of the galaxies was accepted as the conceptual proof of the physical expansion of space. I will recount how the recession of the galaxies was first discovered and eventually accepted as a physical model for the expansion of the universe.

Nationalist Parties - Professor Vernon Bogdanor FBA
 
01:00:05
Between 1886 and 1914, British politics was dominated by the Irish Question, and the Irish nationalist party exerted considerable pressure on British governments. Since 1974, the rise of the SNP has brought the Scottish Question into the forefront of British politics, and in 1998, legislation provided for devolution to the non-English parts of the United Kingdom. There remain, nevertheless, strong pressures for Scottish independence, and in Wales there is a lively nationalist party, Plaid Cymru. How is the rise of nationalist parties to be explained?

The Search for Dark Matter -  Professor Carolin Crawford
 
01:00:48
An introduction to the hunt for dark matter that takes us up to the most current research and theories: http://www.gresham.ac.uk/lectures-and-events/the-search-for-dark-matter Unlike the stars and galaxies, dark matter does not give off any radiation – we can only detect it through its gravitational pull. It accounts for a quarter of the Universe, yet we do not yet understand what it is made of. The search for a better understanding of dark matter is carried out both out in space and deep underground, and where astrophysics meets particle physics.

Quasars: the Brightest Black Holes - Professor Carolin Crawford
 
58:48
Quasars are among the most dramatic objects anywhere in the cosmos. They emit prodigious amounts of energy, all due to a supermassive black hole at the heart of a galaxy. Visible far across the Universe, quasars can be used to trace both the early life of galaxies, and the properties of the intervening space.

Creativity in Mathematics and the Arts - Marcus Du Sautoy
 
05:04
Professor Marcus Du Sautoy believes that the worlds of Mathematics and the Arts are much closer than we’re led to believe. In this short extract from his lecture on the mathematics that underpins some the work of the greatest artists, he explains how the ‘Eureka’ moment of understanding in the study of maths is similar to the joy of creation in the Arts. This is a short extract from a Gresham Lecture. You can enjoy the lecture in full on our website: http://www.gresham.ac.uk/lectures-and-events/the-secret-mathematicians Marcus Du Sautoy OBE is the Simonyi Professor for the Public Understanding of Science and a Professor of Mathematics at the University of Oxford and he’s interested in how Maths and the Arts work together and how similar processes underlie them.

Incest and Folk-Dancing: Two things to be avoided - Professor Steve Jones
 
01:07:13
How closely are we related to each other, and how recently do we all share an ancestor? The answer to those questions is: closer and more recently than you might think. Professor Jones discusses patterns of relatedness in ancient and modern populations and how they can be measured from the records, from surnames, and - more and more - from the DNA. The pedigree hidden in every genome reveals some quite unexpected patterns of kinship and suggests that some may be very relevant to the chances of disease. However, the evidence that close kinship is breaking down is, in this modern and mobile world, very persuasive and it may be that the most important event in human evolution, and even in human health, was the invention of the bicycle.

Humanity and a Million Years of Sea Level Change - Dr Nicholas Flemming
 
51:52
Homo sapiens evolved over the last million years during which time the climate fluctuated strongly. Ice accumulated and melted again, exposing and flooding the continental shelves - land which was colonised by plants and animals. About 3000 such prehistoric sites with archaeological remains have been found on the sea floor by divers.

What Really Happened at the First Moving-Picture Shows? - Professor Ian Christie
 
49:48
The reception of moving pictures in 1894-96 has been much mythologised. Were spectators really frightened of an approaching train? Did they imagine seeing their departed relatives reanimated on screen? How much attention was actually paid to this new phenomenon among so many contemporary novelties and wonders? Moving pictures may not have been the innovation once claimed, but within a decade few could doubt that they had become a major force in changing the Edwardian world.

The Victorian 'Grand Tour'  -  Professor Richard J Evans, Gresham College history lecture
 
04:32
Tourism for the Victorian era was something very different from what it is today, and a part of this was their belief in the 'backwardness' of Europe in comparison to England. Gresham College Professor, Richard J Evans, explains the sorts of attitudes that Victorians taking a Grand Tour held with regards to the countries they visited. This is the 2nd part of 'The Victorians: Empire and Race'.

Star Dust - Professor Carolin Crawford
 
51:29
Interstellar space is not truly a vacuum devoid of matter. Mixed into vast diffuse clouds of atomic gas are minute grains of silicate and carbonate materials known as 'dust', alongside complex molecules deep in the cold hearts of nebulae. We shall look at how we can detect and observe this tenuous material, through the processes by which dust scatters and absorbs visible light, and emits its own infrared glow. This interstellar matter is of fundamental importance to us all, as it is the reservoir from which all planets form... and any lifeforms living on those planets.

As well as the byzantine politics and open warfare that lead to the creation of Magna Carta, Lord Judge highlights the real hero of 1215, William Marshal, who's tireless campaigning and statecraft lead to the adoption of Magna Carta, ejected the French from British soil and secured the Plantaganet dynasty's hold on the throne The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/magna-carta-the-medieval-context-and-the-part-played-by-william-marshal Gresham College has been giving free public lectures since 1597.

How Energy Flow Shapes The Evolution of Life - Professor Nick Lane
 
01:07:41
Despite the explosion of genetic information in recent years, we have surprisingly little insight into the peculiar history of life on our planet. Most genetic variation natural experiments in evolution is found in simple bacteria, yet they have barely changed over four billion years. No complex animals or plants are composed of bacterial cells. Why not? Why did complex cells only arise once in the history of life? And why are we complex beings so alike, with humans and mushrooms and trees all plotting for sex? Nick Lane will explore the importance of energy flow in shaping life from its very origins to the flamboyant complexity around us, and ask whether energy flow would direct evolution down a similar path on other planets.
