Second
Law of Thermodynamics - The Laws of Heat Power
The Second Law of Thermodynamics is one of three Laws of Thermodynamics. The
term "thermodynamics" comes from two root words: "thermo,"
meaning heat, and "dynamic," meaning power. Thus, the Laws of
Thermodynamics are the Laws of "Heat Power." As far as we can tell,
these Laws are absolute. All things in the observable universe are affected by
and obey the Laws of Thermodynamics.
The First Law of Thermodynamics, commonly known as the Law of Conservation of
Matter, states that matter/energy cannot be created nor can it be destroyed. The
quantity of matter/energy remains the same. It can change from solid to liquid
to gas to plasma and back again, but the total amount of matter/energy in the
universe remains constant.
Second
Law of Thermodynamics - Increased Entropy
The Second Law of Thermodynamics is commonly known as the Law of Increased
Entropy. While quantity remains the same (First Law), the quality of
matter/energy deteriorates gradually over time. How so? Usable energy is
inevitably used for productivity, growth and repair. In the process, usable
energy is converted into unusable energy. Thus, usable energy is irretrievably
lost in the form of unusable energy.
"Entropy" is defined as a measure of unusable energy within a closed
or isolated system (the universe for example). As usable energy decreases and
unusable energy increases, "entropy" increases. Entropy is also a
gauge of randomness or chaos within a closed system. As usable energy is
irretrievably lost, disorganization, randomness and chaos increase.
Second
Law of Thermodynamics - In the Beginning...
The implications of the Second Law of Thermodynamics are considerable. The
universe is constantly losing usable energy and never gaining. We logically
conclude the universe is not eternal. The universe had a finite beginning -- the
moment at which it was at "zero entropy" (its most ordered possible
state). Like a wind-up clock, the universe is winding down, as if at one point
it was fully wound up and has been winding down ever since. The question is who
wound up the clock?
The theological implications are obvious. NASA Astronomer Robert Jastrow
commented on these implications when he said, "Theologians generally are
delighted with the proof that the universe had a beginning, but astronomers are
curiously upset. It turns out that the scientist behaves the way the rest of us
do when our beliefs are in conflict with the evidence." (Robert Jastrow, God
and the Astronomers, 1978, p. 16.)
Jastrow went on to say, "For the scientist who has lived by his faith in
the power of reason, the story ends like a bad dream. He has scaled the
mountains of ignorance; he is about to conquer the highest peak; as he pulls
himself over the final rock, he is greeted by a band of theologians who have
been sitting there for centuries." (God and the Astronomers, p.
116.) It seems the Cosmic Egg that was the birth of our universe logically
requires a Cosmic Chicken...
