Jocelyn Bell Burnell has spent her career studying the universe, as she puts it, using all available wavelengths — from short wavelength gamma and x-ray radiation, to visible light, to long-wave radio waves. Along the way, she's picked up some wave-related and puzzles from around the world, and she presents three in this talk: a two-slit beach experiment, a mystical aztec bird call, and one she just can't explain involving a boat horn on the Danube river!

Jocelyn is an astrophysicist, best known for her discovery of pulsars — rotating neutron stars that appear to ‘pulse’ since the beam of light they emit can only be seen when it faces the Earth. The observation is considered to be one of the greatest astronomical discoveries of the twentieth century.

In 1967, Jocelyn made her discovery using a telescope that she and her supervisor Antony Hewish had originally built to study the recently detected star-like quasars. She noted a signal that pulsed once every second — ‘Little Green Man 1’ — that was later determined to be a pulsar. Jocelyn has since become a role model for young students and female scientists throughout the world.
