My son, Jeff, is Professor of Mathematics, University College London.
It’s a Big Deal. To quote the description of it from the University of Cambridge:
The Adams Prize is one of the University’s oldest and most prestigious prizes. The Prize is named after the mathematician John Couch Adams and was endowed by members of St John’s College. It commemorates Adams’s role in the discovery of the planet Neptune, through calculation of the discrepancies in the orbit of Uranus. Previous prize-winners include James Clerk Maxwell, Roger Penrose and Stephen Hawking.
