The Universe is granulated. Stars, planets and asteroids are all relatively small particles when compared to galaxies (themselves, particles when seen from afar). They are relatively huge when compared to sand particles. The number of atoms in a single particle of sand is roughly the same as the number of sand particles in Australia¹s beaches, somewhere in the vicinity of 10,000,000,000,000,000,000. Together with dry rice, M&M¹s and pharmaceutical powders, sand particles belong to the class of granular materials, the second-most manipulated material in industry (after water). But the motion of sand particles is far less understood than the motion of atoms in water or the motion of celestial bodies and galaxies. What is it about sand particles and rice bubbles that makes them so hard to describe? What governs their motion, and how can they inform us about important phenomena such as earthquakes and volcanoes? This talk will tackle those questions.

Working at the University of Sydney, Professor Itai Einav is the Director of SciGEM (Sydney Centre in Geomechanics and Mining Materials). He is an Honorary Professor of University College London, a Fellow of the Royal Society of NSW, and has held visiting research appointments at Universities in USA, France, Spain and Japan. He is an Editor of granular matter and sits on the editorial board of Géotechnique. He received several international research awards, including medals from UK’s Institute of Civil Engineers and Europe’s ALERT Geomaterials. His work crosses many disciplines at the interfaces of Civil Engineering, Physics, Resources Engineering, Geophysics, and Applied Mathematics. Einav’s work in the disciplinary area of granular physics has yielded discoveries in heat transfer, mixing, segregation and melting. More recently he has developed strong affinity to rice bubbles.
