Models. Behaving. Badly: Why Confusing Illusion With Reality Can Lead to Disaster, On Wall Street, And In Life by Emanuel Derman
"In physics there may one day be a Theory of Everything; in finance and the social sciences, you have to work hard to have a usable Theory of Anything."

The idea that the theories of physics are qualitatively different from the models of finance has been one of the longest running themes on the Psy-Fi Blog – all the way back to this post on
Newton’s Financial Crisis. Now the polymathic ex-theoretical physicist, ex-quant for Goldman Sachs, Emanuel Derman, has written a book on this very subject; and very unusual it is too.
Being Derman this is no ordinary description of the problem, but one that roams widely across the realms of science, philosophy, autobiography and finance. At the heart of the discussion is a key idea, that the Law of One Price is a basis for most securities valuations and works not because it’s a deep law of nature but because it’s a simple rule of thumb that can’t be misused in any meaningful way.
