The Butterfly Effect

The butterfly effect is a the theory that small variations of the initial condition of a system may produce large variations in the long term behavior of that system. For example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position.

Term "butterfly effect" was coined by Edward Lorenz who refferred to the idea that a butterfly's wings might create tiny changes in the atmosphere that may ultimately alter the path of a tornado or delay, accelerate or even prevent the occurrence of a tornado in a certain location. The flapping wing represents a small change in the initial condition of the system, which causes a chain of events leading to large-scale alterations of events. Had the butterfly not flapped its wings, the trajectory of the system might have been vastly different.

In arguably the earliest illustration of the butterfly effect in a story on film, an angel in 'It's a Wonderful Life' (1946) shows George Bailey how rewriting history so that George was never born would detrimentally affect the lives of everyone in his hometown. In a subtle butterfly effect, snow is falling in one version of reality but not the other.

The 1998 British movie 'Sliding Doors' runs two parallel stories of the same woman, Helen (Gwyneth Paltrow). In one universe, Helen manages to catch a London Underground train home on time, and in the other she misses it. This small event influenced her life dramatically.
In many cases, minor and seemingly inconsequential actions in the past are extrapolated over time and can have radical effects on the present time of the main characters.

The second episode in the "Back to the Future" trilogy also vividly illustrates the cascading and broad effects of what seemed a minor change in the course of events: because the loathsome Biff Tannen accidentally gets his hands on a record book from 2015, he is able to grow rich and corrupt Marty Mcfly's home town. When McFly returns to 1985, he finds it utterly degraded from what had used to be.

The lesson for us from the butterfly effect is that small events can trigger significant consequences. A small act can disturb the status quo and bring significant change.

If we make minor adjustments to our everday living, there can be signifcant effects further down the track. What can you do today to that could have a major effect later on?

It's our daily decisions that determines our destiny, and potentially the destiny of others as well.
