Last Wednesday, March 26, 2025, this year's Abel Prize was awarded to the Japanese mathematician Masaki Kashiwara. The Abel Prize is one of the most prestigious honours in mathematics. It is awarded every year by the Norwegian Academy of Science and Letters and comes with a prize money of over £550,000. In this episode of Maths on the Move we talk to Helge Holden, Chair of the Abel Prize Committee. Helge tells us about this year's winner, the history and purpose of the Prize, and how the winners are chosen. He also tells us why good mathematicians are needed in all sectors of science and beyond, and talks about the tragic story of the mathematician Niels Henrik Abel, after whom the Prize is named.
