The Mathematics of Visual Illusions - Ian Stewart Jan 05, 2017

Show notes

Puzzling things happen in human perception when ambiguous or incomplete information is presented to the eyes. In this lecture Ian Stewart demonstrates how these phenomena provide clues about the workings of the visual system. For example, illusions, or multistable figures occur when a single image can be perceived in several ways. In this talk Ian references recent research which has modelled simplified, systematic methods by which the brain can make decisions. Ian Stewart is Emeritus Professor of Mathematics in the University of Warwick.

How can we understand our complex economy? - J. Doyne Farmer Nov 10, 2016

Show notes

We are getting better at predicting things about our environment - the impact of climate change for example. But what about predicting our collective effect on ourselves? We can predict the small things, but we fail miserably when it comes to many of the big things. The financial crisis cost the world trillions, yet our ability to forecast and mitigate the next economic crisis is very low. Is this inherently impossible? Or perhaps we are just not going about it the right way? The complex systems approach to economics, which brings in insights from the physical and natural sciences, presents an alternative to standard methods. Doyne will explain this new approach and give examples of its successes. He will present a vision of the economics of the future as it confronts the serious problems that our world will face. J. Doyne Farmer is Director of the Complexity Economics program at the Institute for New Economic Thinking at the Oxford Martin School and Professor in the Mathematical Institute at the University of Oxford

Autism and Minds Wired for Science Oct 31, 2016

Show notes

Simon Baron-Cohen, Professor of Developmental Psychopathology, Cambridge, and Director of the Autism Research Centre, gives the 2016 Charles Simonyi Lecture on new research into autism.

As he retires from the the Savilian Chair of Geometry, Oxford Mathematician Nigel Hitchin reflects Oct 19, 2016

Show notes

From early mathematical inspiration at school in Duffield, Derbyshire, Nigel recalls his often unplanned progress via Jesus College, Oxford, Princeton, Cambridge and Warwick, before his final return to Oxford. Along the way such luminaries as Michael Atiyah and Simon Donaldson play their part as Nigel talks about time spent with physicists in Cambridge, the Eureka moments when the answers take shape, to his final reflections on a career where the name Hitchin is attached to so many of the tools of modern geometry and which culminated in the award of the 2016 Shaw Prize.

Fashion, Faith, and Fantasy in the New Physics of the Universe - Roger Penrose Oct 19, 2016

Show notes

What can fashionable ideas, blind faith, or pure fantasy have to do with the scientific quest to understand the universe? Surely, scientists are immune to trends, dogmatic beliefs, or flights of fancy? In this lecture, based on his new book, Roger will argue that fashion, faith, and fantasy, while sometimes productive and even essential, may be leading today's researchers astray, most notably in three of science's most important areas - string theory, quantum mechanics, and cosmology. Yet Roger will also describe how fashion, faith, and fantasy have, ironically, also been invaluable in shaping his own work.

Roger Heath-Brown a Life in Mathematics Sep 17, 2016

Show notes

Roger Heath-Brown is one of Oxford's foremost mathematicians. In this interview with fellow Oxford Mathematician Ben Green, Roger reflects on his influences, his achievements and the pleasures that the subject of mathematics has given him. Roger Heath-Brown's work in analytic number theory has been critical to the advances in the subject over the past thirty years and garnered Roger many prizes. On the eve of his retirement Roger spoke to Ben Green, Waynflete Professor of Mathematics in Oxford and himself a leading figure in the field of number theory.

Modelling genes: the backwards and forwards of mathematical population genetics - Alison Etheridge Jul 06, 2016

Show notes

In this lecture Professor Alison Etheridge explores some of the simple mathematical caricatures that underpin our understanding of modern genetic data. How can we explain the patterns of genetic variation in the world around us? The genetic composition of a population can be changed by natural selection, mutation, mating, and other genetic, ecological and evolutionary mechanisms. How do they interact with one another, and what was their relative importance in shaping the patterns we see today?

What We Cannot Know - Marcus du Sautoy May 16, 2016

Show notes

Science is giving us unprecedented insight into the big questions that have challenged humanity. Where did we come from? What is the ultimate destiny of the universe? What are the building blocks of the physical world? What is consciousness? 'What We Cannot Know' asks us to rein in this unbridled enthusiasm for the power of science. Are there limits to what we can discover about our physical universe? Are some regions of the future beyond the predictive powers of science and mathematics? Are there ideas so complex that they are beyond the conception of our finite human brains? Can brains even investigate themselves or does the analysis enter an infinite loop from which it is impossible to rescue itself? To coincide with the launch of his new book of the same title, Marcus du Sautoy will be answering (or not answering) those questions

The Travelling Santa Problem and Other Seasonal Challenges - Marcus du Sautoy Dec 18, 2015

Show notes

The Oxford Mathematics Christmas Public Lecture 2015 examined an aspect of Christmas not often considered: the mathematics. Delivered by Marcus du Sautoy, Simonyi Professor for the Public Understanding of Science. The Oxford Mathematics Christmas Lecture is generously sponsored by G-Research - Researching investment ideas to predict financial markets.

Symmetry, Spaces and Undecidability - Martin Bridson Dec 07, 2015

Show notes

The understanding of the possible geometries in dimension 3 is one of the triumphs of 20th century mathematics. In this talk Martin Bridson explains why such an understanding is impossible in higher dimensions. When one wants to describe the symmetries of any object or system, in mathematics or everyday life, the right language to use is group theory. How might one go about understanding the universe of all groups and what kinds of novel geometry might emerge as we explore this universe? Martin Bridson became Head of the Mathematical Institute on 01 October 2015. To mark the occasion he gave this Inaugural Chairman's Public Lecture.
