Goodbye Edward Lorenz
Yesterday I read that Edward Lorenz died a few weeks ago at the age of 90. In 1961, Lorenz, a Massachusetts Institute of Technology mathematician and meteorologist, developed a mathematical model to help predict weather. For some reason, he decided to reexamine a previous simulation generated by his computerized weather prediction model. In order to save time, he entered data from his previous printout and restarted the computer simulation in the middle rather than at the beginning. Lorenz apparently assumed data from the new simulation would exactly match data from the previous run. It didn’t!
The two simulations quickly began to diverge dramatically and lost any resemblance after just a few “simulation” months. As it turned out, the computer printout from the previous simulation rounded numbers to three digits and the internal computer memory rounded to six digits. Therefore, instead of continuing the simulation with the previously computed number, in this case .506127, the computer restarted the simulation with the rounded number .506. This ever-so-slight variation in the middle of the simulation triggered significant changes in the ultimate outcome of the simulation. Scientists refer to this phenomenon as “sensitive dependence on initial condition.” It is more commonly called the Butterfly Effect.
Years before Lorenz ran his computer simulation, the idea that the flapping of a butterfly’s wings can create tiny changes in the atmosphere that might cause or prevent major weather patterns somewhere else in the world appeared in a short story by Ray Bradbury about time travel. In 1972, when Lorenz failed to provide a title for a planned presentation on this topic to a group of fellow scientists, someone titled his presentation: "Does the Flap of a Butterfly’s Wing in Brazil Set Off a Tornado in Texas?"
Here's the point of the lesson that Lorenz taught us: Seemingly inconsequentially minor events can make all the difference in the world.
Remember, the Butterfly Effect cuts both ways. Minor events can create positive outcomes in the future or prevent negative outcomes. People who understand this are in a much better position to create positive and prevent negative outcomes. What are you doing today, no matter how insignificant it might seem, that will create a positive outcome in the future or prevent a negative outcome? Think about it!
I'm glad people like Edward Lorenz pass through this chaotic world and help us understand it a little better.
