Hello there future internet users, I've been Trace and I will hopefully still be him, and

You've probably heard about the Butterfly Effect -- usually explained by the idea that

a butterfly flaps it's wings in Brazil and causes a hurricane in Texas.

There are millions of butterflies, if every one caused the beginnings of a storm Earth

The thing is, that's not what the Butterfly Effect is about.

It's about how tiny changes in big systems, can have complex results.

Systems, in this case, could be anything from weather patterns, to how big groups of asteroids

For an example of a system: picture a Tilt-a-Whirl ride at a carnival.

If you don't know what that is: it's a rotating and shifting platform, with shell-like cars,

each rotating on a smaller circle, with people inside.

It has rules, and follows those rules rigidly: the platform rotates the same every time,

and the carts can only rotate around specific points…

By analyzing this, you can see the butterfly effect in action.

If I sit alone in one of the tilt-a-whirl carts, it would spin completely differently

Together we'd be heavier and so our cart would have a completely different ride!

Every spin would be completely different from taking the ride alone.

Now, imagine all the carts as part of a system.

With tiny changes to each: someone being a little lighter or heavier in one cart, someone

sitting forward on the seat or with their back on the wall...

These tiny variations affect the WHOLE Tilt-a-whirl system!

That's the butterfly effect -- which does have a scientific name: "sensitive dependence

This was originally discovered by an MIT mathematician and meteorologist Edward Lorenz, who was using

an old computer to calculate weather patterns.

He ran a simulation, and wanted to see it again.

The first time, he put in the data to six decimal places, but figured the second time

those tiny fractions of a degree wouldn't matter, so he only used three decimal places.

In the end, because he cut out a few fractions of a fraction, the whole simulation completely

And that's when the crap hit the counter.

At the time mathematicians thought, if you changed it a little at the start, it would

It was logical, but these "systems" don't behave that way, and we needed new math to

Chaos Theory, by definition, deals with "complex systems whose behavior is highly sensitive

It appears to be chaos, but it's actually governed by the same rules as everything else

But because there are so many moving parts; it's impossible for us to comprehend them

Imagine watching all the people get on a Tilt-a-Whirl and then guessing how every cart is going

Chaos Theory was groundbreaking when it was discovered, because it threw off classical

Isaac Newton's laws of nature -- equal and opposite reactions and such, were imagined

in a "clockwork universe," not one filled with apparent chaos.

Basically, if we understood the basic rules of the universe, we should understand everything

Because even a tiny change in something with as many moving parts as the universe would

mean any assumptions we make would be astronomically wrong.

We went from grasping a good chunk of our universe, to who knows where.

But, the universe is not random, it's governed by RULES.

Rules which mathematicians have worked on understanding for centuries.

Take nature for example, it might seem random, but it's governed by rules, and that's why

These are called FRACTALS, and they show us how chaos is really order.

[pause] It's an infinitely complex, repeating pattern that appears chaotic at times, but

Chaos theory is an attempt to approximate and understand all the people getting on the

Tilt-a-whirl, and how the tilt-a-whirl will react to their actions; thus finding order

The more we understand the math, the better handle we will have to predict how a complex

The practical applications are huge from understanding the brain, to social interaction, to how gas

A study in the Journal of Family Psychology followed 95 couples, attempting to predict

They were correct 87 percent of the time.

Turbulence and weather slash climate change models keep getting better with as we gather

more data, because we can harness that chaos math.

The rules that govern fluid dynamics are pretty well understood.

We get temperature, pressure, volume, and mass, we get solar energy and gaseous emissions,

But, if somehow, a tiny bit of moisture, dust, heat or cold causes a cloud to form somewhere

we didn't expect… the whole system can be thrown off.

Which is why the National Weather Service runs the same weather models again and again:

tweaking it each time -- eventually they getting an inkling of the true result.

So, when you think of the butterfly effect, what should you think of?

The original model Lorenz was working on appeared to spit out chaos, until it was graphed…

and then it looked like this: [show picture?]

It didn't get it's name from an actual butterfly, but from the graph of chaos becoming order.
