Highly energetic particles from outer space travelling at the speed of light, known as cosmic rays, originate from the sites of extreme particle acceleration in the Universe.
When light is dispersed into its constituent colours, it can become possible to discern rich dynamical information about an evolving system in space, for example cosmic explosions, collisions or accelerations.
In 1930, the great physicist Wolfgang Pauli invented a new particle to save the principle of energy conservation in certain radioactive decays he was studying.
Scriabin was Rachmaninov’s classmate at the Moscow Conservatoire, and enjoyed comparable fame during his lifetime, and yet today he is much less known, especially outside Russia.
This lecture will look at change ringing, which is ringing a series of tuned bells (as you might find in the bell tower of a church) in a particular sequence, and this has exciting mathematical properties. We will also ask: why are bells bell-shaped?
Boris Ord composed one tiny Christmas carol – ‘Adam lay ybounden’. But Ord’s largest contribution to the carol genre was his work as choirmaster at King’s College, Cambridge from 1929 to 1957.

Over the last 30 years, digital technology produced an exponential increase in astronomical data. Within our lifetime, the entirety of the visible universe will have been mapped out: we will have seen everything there is to see. The question will then be: what does it all mean?
