We saw earlier that logic was the ideal of a world of truths "already there" ready to be unveiled. We have also seen that the use of the actual number sobeys ess portal allowed to make this view ideal compatible with the reality of a world that is never exhausted by our measurements. I think that such a way of seeing things is illusory, it is a negation of temporality: the present reality is revealed in the immanence of experience but pre-exist him. In support sobeys ess portal of this, we noticed that modern physics discretize measures and reintroduced the temporality of experience through the use of probability and contextuality action. The world is no longer an infinite and information already there, but a permanent renewal.
To complete this series of articles, I just want to return to what constitutes a commonplace of popular science, sobeys ess portal namely the law of increasing entropy understood as "explaining" the possibility of the irreversibility of time on a Basic reversible temporal laws.
Entropy first expressed in thermodynamic quantity of usable energy, if a gas is a cold side and hot on the other, it is possible to use this temperature gradient to create the mechanical energy ( eg hot steam locomotive air in a colder environment can actuate a piston). It is known that inhomogeneous mixture of hot gas and cold eventually warm. The entropy of a gas with temperature gradient is low, the entropy of the warm gas is high, and the second law of thermodynamics states that the entropy necessarily increases with time.
In statistical physics, entropy sobeys ess portal of a macroscopic state corresponds to the number of possible microstates giving rise to this macro-state. Take a pool table with two balls. Divide the table into two equal parts. If the macro-state is the number of ball in each of the two sections (zero, one or two) and the micro-state to the precise position of each ball on the pool table, you will notice that there are more different microstates corresponding to the macro-state "a sobeys ess portal ball on each side" sobeys ess portal that macro-state "two balls right" or "two balls left." This combinatorial effect is all the more important as the number of balls is great if you place ten randomly ball on the pool table, it will be much more likely to have 5 on each side that the ten of one side .. The entropy is high in the former case and weak in the second variant with the log of the number of possible micro-states (that is to say that each loop thereof, the entropy is incremented by a constant value).
We can show that these two definitions are actually equivalent: temperature, average value of particle velocities of a gas, is for a macro-state with respect to the particular speed of each particle, and the low entropy of a gas thermodynamics corresponds to the case where the macro-state (the temperature sobeys ess portal in different places) corresponds to a smaller number of possible micro-states. The second law of thermodynamics becomes a kind of probabilistic tautology: the entropy can only increase because at microstate of equal probability, it was even more likely to be in a given macro-state the number of microstates is great. Luck so we also have more to progress to a condition that statistically, the entropy increases.
Finally, in information theory, entropy expresses the irreducible aspect of information. Again, this definition is equivalent, since a low entropy state statistics can be encoded sobeys ess portal with less information (to the extreme, if the macro-state corresponds to a single microstate, sobeys ess portal simply specify the macro-state sobeys ess portal to hear the micro-facto state). It is in this sense that we sometimes speak of entropy as a measure of disorder: an incompressible condition is considered disordered, the order constituting a form of data compression.
As a result, popular science often gives us a picture of the universe doomed to end up in a thermal state of death, in which the islands sobeys ess portal of decreasing entropy, sobeys ess portal as life on earth, can not exist locally and temporarily by feeding on "negative entropy" (the relative lack of entropy) of their environment (including sobeys ess portal the Sun), ie accelerating sobeys ess portal especially the thermal death of their surroundings.
The interesting aspect of entropy is that it seems to reintroduce a temporal irreversibility on the basis of reversible physical laws. Thus one could argue that if a glass can "break" and not to "de-break" is because sobeys ess portal the first movement has vastly more likely sobeys ess portal to occur statistically
