Sci Guys
Sci Guys is a podcast all about the weird and unbelievable ways that scientists learn about the world around us. Each week, Corry (@notcorry) tells the story of a particularly strange scientific study while his cohost Luke (@lukecutforth) does his best to derail the conversation with questions, jokes, and whatever nonsense he can think of.
