Speaker: Dr Michael Tarbutt
How can you measure the shape of something so small that you can't even measure its size? This talk will be about an experiment that measures the shape of electrons. Are they spherical or are they slightly egg-shaped? The shape of an electron is important in physics because it is connected to two basic symmetries of nature. The first is a symmetry between the forward and backward flow of time, and the second a symmetry between matter and anti-matter. The talk will explore these connections, showing how extremely precise measurements made in a small laboratory experiment can answer some big physics questions.
