All The Code You Never Gave Me

Equations as icons

When the 14-year-old Richard Feynman first encountered eiπ + 1 = 0, the future physics Nobel laureate wrote in big, bold letters in his diary that it was "the most remarkable formula in math". Stanford University mathematics professor Keith Devlin claims that "like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler's equation reaches down into the very depths of existence". Meanwhile Paul Nahin - a retired US electrical engineer - says in his recent book, Dr Euler's Fabulous Formula, that the expression sets "the gold standard for mathematical beauty".

For some people this expression, named after the 18th-century Swiss mathematician Leonhard Euler, even seems to have become an icon, having special significance apart from its mathematical context. It once even served as a piece of evidence in a criminal trial. In August 2003 an eco-terrorist assault on several car dealerships in the Los Angeles area resulted in millions of dollars worth of damage when a building was set alight and over 100 vehicles were destroyed or defaced. The vandalism included graffiti on the cars that read "gas guzzler" and "killer" - and, on one Mitsubishi Montero, eiπ + 1 = 0. Using this as a clue and later as evidence, the FBI arrested William Cottrell, a graduate student in theoretical physics at the California Institute of Technology, who was later tried and convicted. Cottrell testified at his trial that "Everyone should know Euler's theorem".
