**James Clerk Maxwell**

James Clerk Maxwell (1831-1879) was one of the most important mathematical physicists of all time, after only Newton and Einstein. Within a relatively short lifetime he made enormous contributions to science which this lecture will survey. Foremost among these was the formulation of the theory of electromagnetism with light, electricity and magnetism all shown to be manifestations of the electromagnetic field. He also made major contributions to the theory of colour vision and optics, the kinetic theory of gases and thermodynamics, and the understanding of the dynamics and stability of Saturn's rings.

Raymond Flood has spent most of his academic life promoting mathematics and computing to adult audiences, mainly through his position as University Lecturer at Oxford University, in the Continuing Education Department and at Kellogg College. In parallel he has worked extensively on the history of mathematics, producing many books and writing diverse educational material.

He is Emeritus Fellow of Kellogg College, Oxford, having been Vice-President of the College and President of the British Society for the History of Mathematics before retiring in 2010. He is a graduate of Queen’s University, Belfast; Linacre College, Oxford; and University College, Dublin where he obtained his PhD.

He enjoys communicating mathematics and its history to non-specialist audiences, as he has done recently on BBC Radio 4’s *In Our Time* and on transatlantic voyages with the QM2. Two of the most recent books with which he has been involved are *The Great Mathematicians, *which celebrates the achievements of the great mathematicians in their historical context, and *Mathematics in Victorian Britain*,which assembles into a single resource research on the history of mathematicians that would otherwise be out of reach of the general reader.

His first year of lectures as Gresham Professor of Geometry was titled *Shaping Modern Mathematics*:

The 19^{th} Century saw the development of a mathematics profession with people earning their living from teaching, examining and researching and with the mathematical centre of gravity moving from France to Germany. A lot of the mathematics taught at university today was initiated at that time. Whereas in the 18^{th} Century one would use the term *mathematician*, by the end of the 19^{th} Century one had specialists in *analysis, algebra, geometry, number theory, probability* *and statistics*, and *applied mathematics*. This series of free public lectures looks at the shaping of each of these mathematical areas and at the people who were involved.

Professor Flood continues his Geometry series in the 2015/16 academic year, entitled 'Great Mathematicians, Great Mathematics'.

Professor Flood's previous lecture series' are as follows:

2014/15
