Prof. Alan Davies, University of Hertfordshire
We are all familiar with soap bubbles, indeed who has not enjoyed passing the time by blowing bubbles? But how are they formed? Why are they spherical? What causes the beautiful colours that shimmer in a bubble? To answer these questions, we shall start by describing how soap films form and how they produce bubbles. We shall describe the properties and structure of films and bubbles
both static and when they vibrate. The talk will include a variety of practical demonstrations including how soap films may be used to solve problems such as the routing of cable and power lines.
