Two of my old colleagues were interviewed on the CBC radio science show Quirks and Quarks recently. This is the show I used to listen to in my youth in Canada. In March, astrophysicist Arif Babul, a classmate at the University of Toronto, talked about recent work he had done on abnormal clumping of dark matter in a collision site between clusters of galaxies. Here is the link. Neuroscientist Sebastian Seung, whom I’ve known since graduate school, talked about his recent book Connectome. Link here. I was impressed by how well both were able to explain their work in clear and simple terms. Their use of metaphors was particularly good. I think these are two very good examples of how to talk about science to the general public.
