John Mighton on math; a new approach to fighting cancer; Clearview A.I., Gus from Fogo Island - a podcast by CBC Radio

Canadian mathematician John Mighton believes anyone can become good at math, and that if we understood numbers better, we could solve big problems in the world. Oncologist and author Azra Raza thinks our approach to fighting cancer is putting money in the wrong places — and she's got another way; the unmasking of a shadowy facial recognition software is raising concerns about the end of anonymity; and one of our favourite guests of the week, Gus Penton of Fogo Island, Newfoundland, tells us how he and his neighbours fared during #Snowmageddon.
