This episode is an interlude for the "Things that make you go mmmmm?" series. It provides, I hope, some helpful advice for "spotting errors" motivated by my recent readings of certain other "popular science" books where I kept spotting certain errors, mistakes and misconceptions. My conclusion: the writer lacked something like a more coherent worldview. I present a very brief exposition of an alternative: namely to have a coherent worldview and what that could look like.
