[Introductory text]

  • Luca Turin (biophysicist): The Secret of Scent: Adventures in Perfume and the Science of Smell (2006).
  • Mitchell N. Charity (“software engineer out of MIT”): I must admit, this man is a bit of a mystery to me. All I know is that one night back in 2013 (or was it 2014?) I found myself–as I sometimes do–digging deep into the Internet on the scholarly trial of something I cannot now recall. Anyhow, what I found at the bottom of one particularly deep rabbit hole was an “unfunded personal hobby” site created by Charity himself, A View from the Back of the Envelope (1997). I spent many hours perusing the pages of his site, in/on which he reflects on topics such as “scale,” “uncertainty,” “estimation,” “numeracy,”  “description,” and “deep understanding.” He is incredibly smart, and his public reflections are both thoughtful and thought provoking. More recently, I uncovered two of his other personal hobby sites, How Big are Things? (2002) and ClarifyScience.org (2012). I’ve been meaning to email him about some interests we have in common, and I hope to do so sooner rather than later.
