The Wonderful World of Soapy Surfaces - Dr Mark Walsh

Tuesday, November 9, 2021 - 10:00 to 11:00
Online - Zoom

Join Dr Mark Walsh from Maynooth University to discover all about bubbles!!! Why are soap bubbles round? If a piece of wire, closed into a loop, is dipped in soapy water, what determines the shape of the soap film formed? What happens if we replace the wire loop with a more complicated shape: a wire cube, a pyramid etc? Behind the answers to these questions are fundamental Mathematical principles. These concern basic notions from geometry: shape, area and curvature. Intuitively, these principles are quite simple to understand. However, when applied in practice, they can lead to some surprising and beautiful results! In this talk, we will make use of some basic household supplies and a little geometry to explore the wonderful world of soap films!

About Mark: Dr Mark Walsh is a Lecturer in Mathematics at Maynooth University, specialising in the areas of Geometry and Topology. Before joining Maynooth in 2017, he was Associate Professor of Mathematics at Wichita University, Kansas, USA. Dr Walsh also spent time at WWU Muenster, Germany as well as Oregon State University, USA and the University of Oregon, USA, where he obtained his doctorate in 2009. Dr. Walsh is originally from Leixlip and attended Scoil Eoin Phoil and Colasite Chiarain, before completing his undergraduate and master's studies at Maynooth University.

This demonstration is open to aimed at 4th, 5th and 6th primary school classes and will include some elementary Mathematical content, mostly in picture form.
