Gresham College Lectures

Many of us have been in a medical scanner and benefited from its use in medical diagnostics. But how many of us have considered how it works? The maths behind modern medical imaging (showing how CAT, MRI and Ultrasound scanners work) will be explained, showing how mathematics done in 1915 is now saving countless numbers of lives.

Recent advances in mathematics are leading to much better images for doctors to use for their diagnoses; and similar methods and ideas are used in diverse applications such as remote sensing, oil prospecting, crime detection, studying bees and saving the whales.

Productivity growth in the UK economy has lagged behind that of our major trading partners. With little or no growth in labour or total factor productivity, there can be no solution to our economic problems and a return to what we have come to consider as normal times.

We will examine a number of possible explanations ranging from the role of finance to the employment of physical and human capital.

The Milky Way galaxy was once ablaze with bright young stars. Today, star formation has calmed down, but we glimpse intense pockets of gas that are forming massive stars, testifying to the brilliant past. Stars form in clouds of interstellar gas that orbit their host galaxy. The clouds acquire more mass as gas accumulates, and the gaseous nebulae are soon massive enough to become unstable, due to the pull of their own gravity. As the clouds collapse, their central regions fragment into dense clumps of cold gas that eventually form stars.

Dust particles are the key ingredients that eventually coalesce to form a disk-like structure with rocky cores that orbit the forming sun and agglomerate into planets. The entire solar system was formed out of interstellar grit.

The Thames is the reason that London is where it is and the river has had a decisive influence on the growth of the city since Roman Times. For 500 years it was the only reliable way to move about but in the sixteenth and seventeenth centuries changes came that were to alter the face of London and transform our relationship with the river.

This event is part of Totally Thames 2017 that runs from 1-30 September

During his tenure as Gresham Professor of Law (2012-2016), Geoffrey Nice tackled subjects as diverse as genocide, the law's role in sexual conduct, and whether lawyers really are scoundrels.

To mark the publication of these lectures, Sir Geoffrey will be revisiting some of his key themes in the light of some changes that have taken place across the world since - and to offer his personal view.

His book - Justice for All, and How to Achieve it - will be available for the first time at the event.

Value is the importance, worth or usefulness of something. In healthcare, it has been argued that the only value that matters is that to the patient.

This lecture considers this hypothesis and the relationship between clinical outcome and cost of treatment.

The question of whether we are alone in the Milky Way (or in the universe) is one of the most intriguing questions in science and astronomy. Our solar system formed half way through the history of the universe, and many sun-like stars that host planetary systems are billions of years older than our Sun.

The odds of finding evidence for life are unknown, but the search continues as astronomers observe the nearby universe for earth-like planets and seek signs of life on exoplanets that resemble the earth in terms of atmosphere, composition and climate.

The answer to 'are we alone?' affects our claim for being special in the cosmos, and we shall never know unless we search.

William Shakespeare spent his schooldays learning Latin. When he arrived in London and became an actor and playwright, he discovered a city and a culture that modelled itself on ancient Rome.

Jonathan Bate tells the story of how and why Shakespeare was steeped in the classics, from his earliest plays such as Titus Andronicus and The Comedy of Errors to his dramatisations of the stories of Julius Caesar and Antony and Cleopatra.

Pain is often seen as universal and timeless, but how have people's understandings of pain changed over time? Did the invention of more effective analgesics and anaesthetics really revolutionise medical practices and human relationships to suffering?

Pain forces sufferers to 'pay attention' to their bodies. The way people-in-pain communicate their suffering has a profound effect on the type and quality of care they receive.
