RIP: Edward Lorenz

Very sad to see that Edward Lorenz, one of the founding fathers of Chaos Theory, has died.

There can’t be many people who aren’t familiar with the concept expressed in the title of his 1972 paper “Predictability: Does the Flap of a Butterfly’s Wings in Brazil Set Off a Tornado in Texas?”
Lorenz was awarded the Kyoto Prize in 1991 for his work on determinsitic chaos — “a principle which has profoundly influenced a wide range of basic sciences and brought about one of the most dramatic changes in mankind’s view of nature since Sir Isaac Newton.”
