Algorithms, loosely translated, are systems for doing things. Algorithms are thus the link from pre-history to the modern world - without algorithms we would have an inanimate universe without all the mess and complexity of real life. It turns out that the history of algorithms is messy. There are also general theories of algorithms, and those ideas are not messy at all; they are very beautiful, powerful and should be required reading for the internet age. A lecture by Richard Harvey 20 October ...

Traditionally a lawyer's own views and political affiliation are irrelevant to the pursuit of the legal process. This lecture will examine - and celebrate - the work of lawyers who have crossed the usual lines and worked for political change. It will look at the life of South African advocate Bram Fischer, who defended Nelson Mandela at the Rivonia trial, and was himself prosecuted for sabotage and sentenced to life in prison. It will consider modern examples of lawyers paying a heavy price for ...

The relative role of the State and the individual is a recurring theme of political theory. It is also a practical question in public health - what are the respective responsibilities of government, individuals and healthcare professionals to protect health? This lecture will explore the areas government is widely perceived to be responsible for, ones where government should have no role, and the areas where medical professionals provide a third dimension to a triangle of responsibility. A lectu...

In the face of enslavement, colonialism and cultural suppression, peoples of African descent have fought to maintain cherished cultural practices. Dr Gus Casely-Hayford, the new Director of V&A East, tells the story of how that resistance came to inspire the creation of some of the most dynamic artistic practice of the modern age.

Was Covid-19 the ultimate wake-up call about how we live on planet earth? Looking at the effect on the environment of a near-stoppage of the world's economies, the first lecture explores emerging perspectives and some of the guiding principles about surviving and thriving when we have a greater understanding of nature. These experiences are used to throw light on how some of the traditions of indigenous peoples mirror our scientific understanding of how the natural world functions. A lecture by ...

Pattern and structure are essential to music, from the permutations in a Bach fugue, to the structure of a round. This lecture will explore the mathematics of musical symmetries, such as the "translational symmetry" of the transposition of keys, and the "rotational symmetry" of the duet "Der Spiegel", attributed to Mozart. It will go on to explore the last century's experimentation with the use of mathematical forms to produce intriguing effects, including in the works of Arnold Schoenberg and P...

Eve was the original Evil Woman. She was tempted by Satan, introducing sin into the world. In turn, she seduced Adam, bringing the wrath of the Creator upon humanity for all eternity. From the 2nd century, Eve has been blamed for evil. The innocence of the Virgin Mary simply magnifies Eve's weakness and this continues to resonate in western texts. The fig-leaf covering Eve's genitals is a reminder of the carnality of evil as well as its feminine origins. A lecture by Joanna Bourke 8 October The ...

Clinical practice is often seen as the acquisition and application of scientific knowledge to diagnose and treat diseases. Yet every patient is different. This lecture draws on a ten-year collaboration with a Savile Row tailor to explore 'bespoke' as a metaphor for clinical practice. Using this approach, the knowledge and skill of a practitioner must intersect with the needs of the patient to create a unique solution for each problem. With Joshua Byrne (bespoke tailor) A lecture by Roger Kneebon...

On the 200th anniversary of the birth of Friedrich Engels, his biographer Tristram Hunt looks at how both Engels and Karl Marx were deeply affected by their time in London in the second half of the 19th century. London, then the heart of the British Empire, transformed the thinking of these two revolutionary philosophers on finance, on working people's lives, on cities, and on women voting. Hunt will look at the remarkable personal and family lives of the 'The Old Londoners' as they became known...

Following the Beagle voyage, Darwin settled down to a quiet married life, relying on correspondence to gather facts. He wrote thousands of letters as he gathered facts to support his still-secret theory. Long before anyone had heard of evolution, Darwin produced four enormous books on barnacles, which helped establish his credentials (even his most committed opponents acknowledged that he couldn't be ignored). And the books were also Darwin's attempts to answer some complex questions about sex t...

It will cover the importance of a proper death investigation, the impact on the family and state, how Magna Carta influences death investigations 800 years on, and current trends and statistics in state deaths. How does the state show it cares when deaths occur? Does the state learn lessons? How can the bereaved move on? A lecture by Leslie Thomas QC 1 October The transcrip...

2020 marks the 25th anniversary of the Srebrenica massacre and the Dayton Accords resolution of the first two (Croatia and Bosnia) of the three Balkan wars of the 1990s. In examining the legacy of this conflict, Professor Nice will consider documents newly-released by the UK and US governments. Did the UK and US know what was coming and fail to act? Was the massacre the result of cold blooded politics that was never acknowledged? A lecture by Geoffrey Nice QC 29 September The transcript and down...

Musorgsky was a proficient, but not virtuosic pianist: in his youth, he entertained society ladies with popular marches and quadrilles, and in his last years, he toured as an accompanist in song recitals. On the basis of these modest exploits, no one could have predicted his Pictures at an Exhibition. This cycle of piano pieces is a kind of travelogue, following a Russian at home and abroad. We tour around the Russian Empire and beyond, and we are also invited to contemplate the drawings of Muso...

England's Catholic Reformation is the reformation that sixteenth-century England nearly had: a reformed and renewed English Catholic Church, its new schools and revived parishes matched with a firm smack of discipline. It almost happened; its leading prophets - Cardinals Thomas Wolsey and Reginald Pole - both came close to being elected pope. Instead, as these possibilities evaporated, they left behind them a toxic residue which has poisoned England's relations with its neighbours down to the pr...

Mars has changed since it formed 4.6 billion years ago. When life started on Earth ~4 billion years ago, Mars was habitable too, with volcanism, a magnetic field, surface water and a thick atmosphere. Today, Mars is cold and dry, with a thin atmosphere and harsh surface. In this lecture Professor Andrew Coates will discuss the search for life beyond Earth on our closest target, using the Rosalind Franklin rover.

The Efficient Market Hypothesis argues that stock markets are rational - they take into account all relevant information, and incorporate it in an unbiased way. This talk will present evidence that stock prices are instead driven by human psychology. The market overreacts to some types of information yet underreacts to others; it is driven by emotions rather than purely economic fundamentals. The lecture gives profitable trading strategies that investors can use to exploit these biases. A lectur...

In 1920, Nellie Melba's singing was transmitted to Europe and Newfoundland via the wireless. In 1922 the BBC began broadcasting, and from the outset sponsored new music and relayed outside broadcasts to the nation (and from 1932, to the world). In 1927 the BBC took over The Proms, and in 1946 the Third (alongside the Home and the Light) Programme was instituted. The BBC's mission: 'to be ahead of its public, but not so much as to lose their confidence'. A lecture by Jeremy Summerly 17 September ...

The story of the Mayflower is usually presented as a tale of persecuted Pilgrims crossing the Atlantic in circumstances of grave adversity to inhabit a desolate wilderness. There is another perspective. This lecture asks not where did they go to, but where did they come from? Who paid the piper? Who called the tune? Who hosted and protected them for years before the voyage, and who taught them the tolerant values that 17th century Puritans usually lacked? A lecture by Graham Taylor 18 September ...

The COVID-19 pandemic has been devastating. But one silver lining has been the tremendous responses from businesses and individual citizens, as we've realised how even small actions can have a substantial effect on society. A second is that the crisis has caused us to step back, focus on what is truly important rather than merely urgent, and appreciate gifts we normally take for granted. This lecture will draw leadership lessons from the crisis that we can apply to life post-pandemic. A lecture ...

Like James I, King William III was fundamentally unhappy with the stuffy formality of England's vast crumbling royal estate. But unlike James, who virtually abandoned Edinburgh, William maintained a second court, and a parallel suite of royal houses, in the Netherlands. Mostly ignored by English historians, these houses are the key to understanding the style that we now know as William and Mary, and its impact on England.

It is commonplace for governments to complain that the cost of healthcare is rising. Various reasons are put forward: some claim that modern medicine is inevitably more expensive; some claim that the ageing population is the cause of the problem; others opine that the only option is rationing. But what are the opportunities for using Information Technology to reduce the cost of healthcare? And what might our healthcare system look like in 10 years time if we make judicious investments in technol...
