How can you measure the shape of something so small?
This lecture will be about an experiment that measures the shape of electrons. Are they spherical or slightly egg-shaped?
The shape of an electron is important in physics because it is connected to the basic symmetries of nature. The first is the symmetry between the forward and backward flow of time. The second is the 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 of the big physics questions.
