48 - Micrographia

Germs are regarded today with a combination of fear and disgust. But mankind’s first introduction to the microbial world started off on a very different foot. In this episode, as part of a larger series contextualizing germ theory, we’ll talk about the discovery of animalcules and how they forever changed our conception of the natural world -- and what causes disease. Plus, a new #AdamAnswers about the influence of Bayes Theorem on medicine!
