Drawing on examples within the interconnected fields of philosophy, psychology and history, Dr Stefan Buijsman explores the role mathematics plays in the modern world.
Stefan Buijsman was born in 1995 and gained a master's degree in philosophy in Leiden at the age of eighteen, after which he moved from Sweden to work on a PhD. Within eighteen months (instead of the usual four years) he gained his doctorate, making him one of the youngest ever PhDs. He is currently studying the philosophy of mathematics as a post-doctoral researcher. Along with Govrien Oldenburger he is the author of a children's book The Kingdom of Sums (2018). He lives in Amsterdam.
