I must add my voice to economists (Hal Varian most recently, along with Roger Myerson and Paul Krugman) admitting that Isaac Asimov’s Foundations Trilogy was a favorite of mine when I was young. Sadly, I have turned out to be no where near the quality of theorist these men are.
Since reading it the first time, I have become a literary snob (yes, James Joyce’s Ulysses is my favorite novel), so I must agree with Sandeep Baliga when he says "I enjoyed reading the first book in the trilogy and it’s clear how it might excite a teenage boy with an aptitude for maths. The next two books are much worse. I struggled through them just to find out how it all ended. Perhaps I read them when I was too old to appreciate them."
