The Matter Myth: Chapter 2 Analysis

            The second chapter of this book is titled “The Liberation of Matter”. As the title suggests, this chapter discusses the freeing of matter from the deterministic Newtonian world view. The authors go into detail about the chaos theory and explain the difference between chaotic and non-chaotic systems. The laws of physics and laws of chance are tied together by the chaos theory. Heisenburg’s uncertainty principle is also briefly mentioned in this chapter.
            Following the formulation of the laws of mechanics, scientists worldwide accepted the view of the Universe as a gigantic mechanism. In one case, Pierre Laplace, a nineteenth century scientist, believed that at any instant in time, Newton’s laws could explain the position of everything with extreme precision. Along with this belief came the belief that true chance processes do not actually exist. For example, the flipping of a coin is only viewed as a chance process because we are not capable of viewing every factor affecting the result of the flip.

(above) Is the flipping of a coin a true chance process or can the result be determined by calculating every factor on the coin?
A non-chaotic system is system in which a lack of input precision translates into a similar lack of output precision. For example, if your initial information about the position of an object falling is incorrect, your final velocity calculations will carry a similar small error. A chaotic system is a system that amplifies input errors. In contrast to a non-chaotic system, a chaotic system would make a lack of input precision noticeable.
Although Newton’s laws allow very precise measurements, they will not provide perfect results. This can be explained by a number line. Fractions are not capable of labeling every point on a number line, but irrational numbers are. Since irrational numbers have an infinite amount of repeating numbers, they cause an unavoidable lack of perfect precision. In a chaotic system, this input error would amplify the output error. It would be impossible to mathematically calculate processes our Universe to infinite precision. This concept may be used to back up Heisenburg’s uncertainty principle, which states that everything we can observe or measure is vulnerable to random fluctuations.
