    Attributing False Attributes to Thermodynamics

    Creationist arguments are often based on assuming that a scientific theory or
    law possesses an attribute that it does not, in fact, possess. The
    creationist thermodynamics argument is a typical example of how this
    technique is used to twist well established scientific principles into
    meaningless gibberish. The reader should refer to Chapter III of "Scientific
    Creationism," edited by Henry Morris of the Institute for Creation Research
    for specific details. This chapter can be summed up as follows.

    Creationist claims:
    1. The second law of thermodynamics requires that all systems and individual
    parts of systems have a tendency to go from order to disorder. The second law
    will not permit order to spontaneously arise from disorder. To do so would
    violate the universal tendency of matter to decay or disintegrate.

    2. Creationists recognize that in many cases order does spontaneously arise
    from disorder: seeds grow into trees, eggs develop into chicks, crystalline
    salts form when a solution evaporates, and crystalline snowflakes form from
    randomly moving water vapor molecules. In cases like these, creationists have
    assigned an attribute that there must be a programmed energy conversion
    mechanism to direct the application of the energy needed to bring about the
    change.

    3. This energy conversion mechanism is postulated to "overcome" the second
    law, thus allowing order to spontaneously arise from disorder.

    4. Creationists believe that changes requiring human thought and effort, such
    as constructing a building, manufacturing an airplane, making a bed, writing
    a book, etc. are covered by the science of thermodynamics. Creationists
    believe that a wall will not build itself simply because to do so would
    violate the laws of thermodynamics. In building the wall, the stonemason
    overcomes the laws of thermodynamics!

    5. In the case of organic change, like seeds growing into trees and chicks
    developing from eggs, creationists believe that the directed energy
    conversion mechanism that overcomes the laws of thermodynamics comes from
    God.

    Comments on the above five claims:
    1. The degree of thermodynamic disorder is measured by an entity called
    "entropy." There is a mathematical correlation between entropy increase and
    an increase in disorder. The overall entropy of an isolated system can never
    decrease. However, the entropy of some parts of the system can spontaneously
    decrease at the expense of an even greater increase of other parts of the
    system. When heat flows spontaneously from a hot part of a system to a colder
    part of the system, the entropy of the hot area spontaneously decreases! The
    ICR chapter states flatly that entropy can never decrease; this is in direct
    conflict with the most fundamental law of thermodynamics that entropy equals
    heat flow divided by absolute temperature.

    2. There is no need to postulate an energy conversion mechanism.
    Thermodynamics correlates, with mathematical equations, information relating
    to the interaction of heat and work. It does not speculate as to the
    mechanisms involved. The energy conversion mechanism can not be expressed in
    terms of mathematical relationships or thermodynamic laws. Although it is
    reasonable to assume that complex energy conversion mechanisms actually
    exist, the manner in which these may operate is outside the scope of
    thermodynamics. Assigning an energy conversion mechanism to thermodynamics is
    simply a ploy to distort and pervert the true nature of thermodynamics.

    3. The use and application of thermodynamics is strictly limited by the
    mathematical treatment of the basic equations of thermodynamics. There is no
    provision in thermodynamics for any mechanism that would overcome the laws of
    thermodynamics.

    4. Thermodynamics does not deal with situations requiring human thought and
    effort in order to create order from disorder. Thermodynamics is limited by
    the equations and mathematics of thermodynamics. If it can't be expressed
    mathematically, it isn't thermodynamics!

    Creationism would replace mathematics with metaphors. Metaphors may or may
    not serve to illustrate a fact, but they are not the fact itself. One thing
    is certain: metaphors are completely useless when it comes to the
    thermodynamics of calculating the efficiency of a heat engine, or the entropy
    change of free expansion of a gas, or the power required to operate a
    compressor. This can only be done with mathematics, not metaphors.
    Creationists have created a "voodoo" thermodynamics based solely on
    metaphors. This in order to convince those not familiar with real
    thermodynamics that their sectarian religious views have scientific validity.

    DNAunion: Of interest here is the following:

    "Assigning an energy conversion mechanism to thermodynamics is simply a ploy
    to distort and pervert the true nature of thermodynamics.

    3. The use and application of thermodynamics is strictly limited by the
    mathematical treatment of the basic equations of thermodynamics. There is no
    provision in thermodynamics for any mechanism that would overcome the laws of
    thermodynamics."

    As others have done, the author switches away from talking about
    thermodynamics as it applies to biology to focussing on ONLY thermodynamics.
    So what? What is wrong with this? Simple, but I will need to use an
    analogy.

    The law of gravity imposes on heavier-than-air objects a tendency to remain
    as close to the center of the Earth's mass as possible: if positioned on the
    ground, that is where they tend to remain: if positioned above the ground,
    they tend to fall until making physical contact with the ground. Yet a
    many-ton hunk of metal can rise above the Earth - airplanes harness energy to
    overcome the tendency gravity imposes on the massive hunk of metal, and all
    times, obeys every known law of physics. So, metaphorically speaking, IDists
    are asking how airplanes can fly: what mechanisms are required to properly
    channel available energy in order for an airplane that weighs many tons to
    rise from the ground instead of following its natural tendency to remain
    grounded. In this question, gravity plays a key role. Yet the counters are
    that engines and pilots and fuel combustion are not parts of the theory of
    gravity! No duh! We aren’t saying they are. Are we not allowed to
    bring gravity into discussions concerning
     full-powered flight of a many-ton aircraft?
