The Cambridge Philosophical Society is pleased to support the 3rd PdOC Research Showcase, taking place on 1st November 2023 at WestHub, Cambridge.

The PdOC Research Showcase is a free, one-day conference open to all postdocs of the University of Cambridge and affiliated institutions (STEMM as well as AHSS). Sign up now to join us for a day full of exciting presentations from your fellow postdocs as well as to learn more about the latest research taking place at Cambridge, and submit an abstract to introduce your peers to your own work or future projects and to get a chance to win our sought after PdOC Best Presentation award. The postdoc presentations will be accompanied by two keynotes given by Prof. David Leslie, an expert on AI policy, Director of Ethics and Responsible Innovation Research at The Alan Turing Institute, and Professor of Ethics, Technology and Society at Queen Mary University of London, as well as Prof. Zoe Kourtzi, an expert for AI in healthcare with a focus on neuroscience, a Turing Fellow, and Professor of Computational Cognitive Neuroscience at the University of Cambridge.

A Lot of Hot Air: volcanic degassing and its impact on our environment

Professor Marie Edmonds FRS

  • 18:00 - 19:00 Bristol-Myers Squibb Lecture Theatre, Cambridge Michaelmas Term Booking Recommended

Volcanoes are hazardous and beautiful manifestations of the dynamic processes that have shaped our planet. Volcanoes impact our environment in numerous ways. Over geological time volcanic activity has resurfaced the Earth and provided life with a terrestrial substrate upon which to proliferate. Volcanic degassing has shaped our secondary atmosphere and as part of the process of plate tectonics, maintained just the right amount of water and carbon dioxide at the surface to produce a stable and equitable climate. Magma in the subsurface in volcanic environments today gives Society geothermal energy. The fluids degassed from magmas in the plumbing systems of volcanoes give rise to hydrothermal ore deposits, the source of much of our copper and other metals, critical to the energy transition. In this lecture I will describe the nature and importance of magma degassing for our atmosphere and oceans, as a source of both pollutants and nutrients, and in the formation of mineral deposits. I will describe my own research in carrying out measurements of volcanic gases (using a range of spectroscopic methods, from the ground and using drones), and analysis of erupted lavas, to understand the chemistry and physics of volcanic outgassing and its role in sustaining our planetary environment.

Cars, aeroplanes, and quantum physics: Why complexity makes life simpler for the vibration engineer

Professor Robin Langley

  • 18:00 - 19:00 Bristol-Myers Squibb Lecture Theatre, Cambridge Lent Term G.I. Taylor Lecture Booking Recommended

One of the many outstanding achievements of G I Taylor was the discovery of relatively simple statistical laws that apply to highly complex turbulent flows.  The emergence of simple laws from complexity is well known in other branches of physics, for example the emergence of the laws of heat conduction from molecular dynamics.  Complexity can also arise at large scales, and the structural vibration of an aircraft or a car can be a surprisingly difficult phenomenon to analyse, partly because millions of degrees of freedom may be involved, and partly because the vibration can be extremely sensitive to small changes or imperfections in the system. In this talk it is shown that the prediction of vibration levels can be much simplified by the derivation and exploitation of emergent laws, analogous to some extent to the heat conduction equations, but with an added statistical aspect, as in turbulent flow. The emergent laws are discussed and their application to the design of aerospace, marine, and automotive structures is described.  As an aside it will be shown that the same emergent theory can be applied to a range of problems involving electromagnetic fields.
