 Entropy and the second law of thermodynamics
Disorder in macro objects is caused by energetic agents (wind, heat, earthquakes, driving rain, people, or, in a quite different category, gravity) acting on them to push them around to what we see as "disorderly" arrangements, their most probable locations after the agent is not actively moving them.
Additional accessible microstates mean that at any instant the total energy of the system is in just one microstate but it has very many more choices for a different microstate the next instant than without “additional accessible microstates”.
Because there are additional accessible microstates in the final state, there are more choices for the system at one instant to be in any one of that larger number of microstates — a greater dispersal of energy on the molecular scale.

 Stoat
His analysis of the impact of warmer sea surface temperature on the stability of the lower troposphere contains basic errors in thermodynamics.
Gray presents an alternative hypothesis for variations of hurricane characteristics in the North Atlantic that involves salinity variations; this hypothesis is not substantiated either in his paper or in the published literature.
Attributing individual hurricanes is difficult/impossible (the line taken by RC); we're talking about over all trends & stats.

 Five Major Misconceptions about Evolution
The thermodynamics argument against evolution displays a misconception about evolution as well as about thermodynamics, since a clear understanding of how evolution works should reveal major flaws in the argument.
When people think about a category like "dog" or "ant," they often subconsciously believe that there is a well-defined boundary around the category, or that there is some eternal ideal form (for philosophers, the Platonic idea) which defines the category.
This shows more a misconception about thermodynamics than about evolution.

 Entropy and the second law of thermodynamics
P: The second big category of entropy increase isn’t very big, but often poorly described in general chemistry texts as "positional" entropy (as though energy dispersal had nothing to do with the change and the molecules were just in different ‘positions’!) It involves spontaneous increase in the volume of a system at constant temperature.
Entropy measures the energy dispersal for a system by the number of accessible microstates, the number of arrangements (each containing the total system energy) for which the molecules' quantized energy can be distributed, and in one of which – at a given instant – the system exists prior to changing to another.
Thus, the definition of entropy as a measure or indicator of the greater dispersal of energy is visibly demonstrated by the plots.

 Category:Statistical mechanics - Wikipedia, the free encyclopedia
It provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic or bulk properties of materials that can be observed in every day life, therefore explaining thermodynamics as a natural result of statistics and mechanics (classical and quantum).
The main article for this category is Statistical mechanics.
Statistical mechanics is the application of statistics, which includes mathematical tools for dealing with large populations, to the field of Mechanics, which is concerned with the motion of particles or objects when subjected to a force.

 e-Misha's Words on Z
A fundamental scientific law, known as the zeroth law of thermodynamics, says that nothing can ever be cooled down to absolute zero.
They were unmatched, he felt, and they went in the category that superseded the first — his zeroth class.
You don't have to be a rocket scientist to use "zeroth," but the word, which was coined by physicists a little over a hundred years ago, does often show up in scientific contexts.

 Thermodynamics - Wikipedia, the free encyclopedia
Most "pure" nonmagnetic substances fall into this category.
Blackbody radiation is an example, since photon number is not conserved.
Such a state is completely described by its temperature, although if phase transitions or spontaneous symmetry breaking occur other variables may be needed to discriminate among the phases.

 Hurricane Isabel
At the time this photo was taken, Isabel had reformed to a Category 5 storm, packing winds of 160 miles per hour.This observation was made on September 13, 2003 by Expedition Seven crew members aboard the Space Station.
Although there has been some restriction of the outflow in the southwest quadrant the current weakening on 15 September may be more a result of less favorable environmental thermodynamics.
Isabel is moving toward the west-northwest near 12 mph, and this general motion was expected to continue for the next 24 hours.

 extensive
For centuries, mathematical philosophy has distinguished between extensive quantities and intensive quantities, for example in thermodynamics of inhomogeneous bodies, volume, mass, energy, and entropy on the one hand are distinguished from pressure, density, temperature on the other.
An intensive quantity type is a contravariant functor from a category of space which also takes coproducts to products ; but more: intensive quantities usually act linearly on extensive quantities, lending them (not only a linear but also a) multiplicative structure which is also preserved by the contravariant functorality.
Their name for your "extensive" is "lextensive", which I think is due to Bill Lawvere; it means "lex and extensive", where "lex' is used to mean "having all finite limits".

P: The second big category of entropy increase isn’t very big, but often poorly described in general chemistry texts as "positional" entropy (as though energy dispersal had nothing to do with the change and the molecules were just in different ‘positions’!) It involves spontaneous increase in the volume of a system at constant temperature.
Second, as does any type of energy spread out in its particular kind of energy levels, the energy of molecular motion spreads out as much as it can on its t, r, and v levels.
The second law just summarizes our experience with those spontaneous happenings and millions of others: All kinds of energy spontaneously spread out from where they are localized to where they are more dispersed, if they're not hindered from doing so.

 List of Publications: Stephen G. Brush
Philosophical discussions of "reduction" often cite the example of thermodynamics (especially the Second Law) and kinetic theory/statistical mechanics, but with inadequate justification.
According to Allchin (2003), Lawson (2002) tried to shoehorn the history of science into a preconceived philosophical category, the hypothetico-deductive method (HD).
Proceedings of the Cambridge Philosophical Society, 53: 651-3 (1957).

 "Origin of Life Prize - Life Origins - Abiogenesis"
Appealing to unknown "laws" as the source of biological instruction constitutes a "category error" of logic theory.
Organisms do not violate the Second Law of Thermodynamics any more than any other physical entity in open systems far from equilibrium.
Appealing to unknown laws constitutes a "naturalism of the gaps," corresponding to supernaturalists' appealing to a "God of the gaps" for scientific explanation.

If a substance is a ferromagnet or a superconductor, for example, it would fall into this category.
This state is completely described by its temperature and pressure, except at phase transitions and perhaps spontaneous symmetry breaking in the ordered phase.
The state is completely described by its temperature except at phase transitions and perhaps spontaneous symmetry breaking in the ordered phase.

 Shakespeare and Thermodynamics - Dam the Second Law!
Activation energy barriers perform as protectors in a totally different category of action, but they safeguard all the individual molecules containing concentrated energy that are constituents of molecular machines.
These kinds of barriers are due to the energy required not only to break bonds between the atoms of metal and concrete (and bone) or between the molecules of wood and plastic but also due to complex energy-requiring atomic rearrangements during the fracture [8].
In summary, activation energy barriers to the second law and biochemical feedback mechanisms which act as pattern protective barriers are the keys to maintenance of our most prized artifacts and, indeed, of all living creatures in our oxygen- and energy-rich world.
