Gresham College presents a lecture by astronomy professor Carolin Crawford on rotation in space. Rotation is a fundamental physical process throughout the Universe. So much is spinning, from planets and stars revolving on their axes, to whole spiral galaxies rotating around their center.  In this lecture Crawford presents the fundamentals of rotational motion, including the concept of angular momentum. This then will be extended to show what observations of rotation can tell us about how planetary systems form and develop, how neutron stars evolve with time, and how rotational motion provides crucial evidence for the presence and distribution of the elusive dark matter.

Professor Carolin Susan Crawford is a British communicator of science, astrophysicist researcher, lecturer and academic based at the Institute of Astronomy and Emmanuel College, Cambridge.
