I’m very slightly sorry to bump other things. But folks who like the history of mathematics, and how it links to other things, and who also like listening to stuff, might want to know. Peter Adamson, host of the History Of Philosophy Without Any Gaps podcast, this week talked for about twenty minutes about Girolamo Cardano.
Cardano is famous in mathematics circles for early work in probability. And, more, for pioneering the use of imaginary numbers. This along the way to a fantastic controversy about credit, and discovery, and secrets, and self-promotion.
Cardano was, as Adamson notes, a polymath; his day job was as a physician and he poked around in the philosophy of mind. That’s what makes him a fit subject for Adamson’s project. So if you’d like a different perspective on a person known, if vaguely, to many mathematics folks, and have a spot of time, you might enjoy.
