Extreme Clocks: Physics with Pulsars

An introduction to pulsars: objects that have more mass than the sun but are only around 20km in diameter, possessing an extremely high rotational stability and a very strong magnetic field. Aris Karastergiou (Physics Lecturer and Senior Research Fellow) describes them as “nature’s ticking clocks” and explains how the changing rate of ‘ticks’ can inform you about the movement of the ‘clocks’.
