Models and Drunks

I am not referring to Gigi or Gisele or Gumble or Griffin.  Rather, "models and drunks" is a contrite summary of a couple of my recent readings that I figured should find their way to this space. (By the way,  this confusion about models has happened before.)

First, models. I have long been a fan of the phrase that "all models are wrong, but some are useful." However, much to my shame, I know not where it came from.  Now I do. Thank you Twitter for enlightening me about George Box and his paper.   Not only am I know aware, but I have been shaken to my core. More on that later.

Second, drunks - and specifically how they walk.  The Drunkard's Walk: How Randomness Rules Our Lives by Leonard Mlodinow (http://leonardmlodinow.com/) is what I call a mathematician's apologetic - an attempt to make math accessible to the masses.   His book is part of my attempt to work through a reading list (again - thanks Twitter!) of math texts.  I give the guy a couple of stars for effort on the mathematical narration, but the real gold is in the cast of characters.  They will be featured in a future post.  In this post, I will leave you with flip flops.
