One of the most interesting subjects I ever encountered is Chaos Theory. Chaos Theory studies dynamic systems that are highly chaotic in behavior which makes these systems very hard to predict. The reason of these systems' chaotic behavoir is their sensitivity to initial conditions, which is more popularly known as the "butterfly effect." Very cool, eh? Actually, Chaos Theory is a complicated area of study of physics, mathematics, and philosophy and I really do not know the whole picture of it and I definitely don't understand the math of Chaos...
