Pulsars are rapidly rotating neutron stars and are some of the most exotic objects in the universe. They are mostly only observable using radio telescopes. In this talk, I will provide an introduction to pulsars and how they are formed in the violence of the supernova collapse of large stars. I will describe how these massive cosmic flywheels can make superb clocks which can be used to conduct unique experiments in gravitation. In particular, they can be used to explore some of the fundamental laws of physics that determine how the universe evolved. |

Prof. Lyne was appointed as Langworthy Professor of Physics at the University of Manchester in 1991 and was elected as a Fellow of the Royal Society in 1996. He became Director of Jodrell Bank Observatory from 1997 to 2006, and has been an Emeritus Professor of Physics at the University of Manchester since 2008. The main areas of contribution have been in searches for pulsars, the characterization of their properties, the measurement of their velocities and the study of their galactic distribution and evolution.
