Life, the Universe & Everything Else is a podcast that delves into issues of science, critical thinking, and secular humanism.
Note: In preparation for the discussion of the Library of Alexandria, Gem reached out to Winnipeg's Millennium Library to ask about the size of their collection. After we recorded the episode, he received a response informing us that the collection contains roughly 338,000 items, which is on the same order of magnitude as the Great Library of Alexandria—but at least some of the items in circulation are going to be non-canon Star Wars novels, so they don't really count.
