Today's summary is about an article written in 1972 by Edward N Lorenz.
In 2008, the last year of Lorenz's life, he said this when asked whether a butterfly can really cause a tornado. “Even today I am unsure of the proper answer”. The question is valuable because it begs the bigger question that nature is highly sensitive to infinitesimal changes. — Fermat’s Library
If the flap of a butterfly’s wings can be instrumental in generating a tornado, it can equally well be instrumental in preventing a tornado.
Chaos: When the present determines the future, but the approximate present does not approximately determine the future. — Lorenz
