Obituary: Edward N. Lorenz (1917-2008) - Meteorologist And Father Of Chaos
Theory., Nature
 









Excerpts: In his book The Essence of Chaos, Lorenz recounts how he came to
discover the extreme sensitivity of his model to small changes. Wishing to
repeat his simulation, he restarted it with numbers that had been printed out
for the start conditions, and left it to go down the hall to fetch a cup of
coffee. On his return, he found that the result was nothing like the previous
one. He soon identified the reason: the numbers from the print-out were rounded
off. In the course of a coffee break, that small error had propagated with
exponential speed to change the result completely.
