Chaos Theory

What exactly is chaos theory? From the understanding of many scientists such as Edward Lorenz, Ian Stewart, and Robert May the chaos theory relatively means the same thing. Each of these scientists contributed to the science of chaos theory.

First and Foremost chaos theory itself comes from the seemingly half-hazard way things seem to happen in its equations, but chaos theory is really about finding the similarities between these seemingly random events in an equation.

Edward Lorenz, a meteorologist, discovered this theory when he was working on a calculation for weather prediction on his computer. He set his computer to use 12 different equations to model the weather. The computer didn’t necessarily predict the weather. It just gave a guess at where the weather might be. Using these twelve different equations he tried running the model of the weather. After the equation was done he went away from his computer. Edwards wanted to see the results of his equations again so to save time he started the equations half way. He entered the number off the printout of the previous equation and let it run. Yet when he looked at his computer again the equation was drastically different as the picture shows.

All of this happened in 1961. The ideas of the time stated that you should have come out with the same results. In this time a scientist would be called “lucky” if they can get measurements with accuracy too 3 decimal places. The ideas believe that the 4th and 5th decimal places couldn’t have that dramatic an effect on anything. Edward Lorenz proved them wrong. This effect later became known as the butterfly effect. Due to its relatively same comparison as a butterfly flapping its wings.

Ian Stewart wrote on Lorenz’s experiment and stated “The flapping of a single butterfly's wing today produces a tiny change in the state of the atmosphere. Over a period of time, what the atmosphere actually does diverges from what it would have done. So, in a month's time, a tornado that would have devastated the Indonesian coast doesn't happen. Or maybe one that wasn't going to happen, does.”#

Lorenz later stated the to predict the weather was impossible. This led him to discover another attribute of the chaos theory. He wanted to make a simpler version of his twelve equation system but he still wanted to keep its “sensitive dep...

...derstand the behavior of a non-linear system you need in principle to study the system as a whole and not just its parts in isolation.

It has been said that if the universe is an elephant, then linear theory can only be used to describe the last molecule in the tail of the elephant and chaos theory must be used to understand the rest. Or, in other words, linear systems in nature are relatively rare, and almost all interesting real-world systems are described by non-linear systems.

Basically chaos theory can be summed up as the mathematical equation for the dramatic world we live in. The chaos theory can be used to describe many things this shows its usefulness. That is why I believe that we will inevitably see chaos theory being used in schools today and maybe it will even head us to the next world of tomorrow.
