Entropy, a measure of disorder, where all things trend toward disorder.
Left to their own devices all things tend towards chaos and buildings such as this church on the Isle of Skye along with the souls within it's grounds will once more return to the earth from whence they first came.

Contemporary dance, Entropy.
This dance is about the hazards of plastic pollution in the ocean. Every piece of discarded plastic is a silent ecological violence, and every indulgence will be a harm to yourself. This dance explores howto choreograph with lightweight and soft props while maintaining the full range of movement exploration.

Entropy is the general trend of the universe toward death and disorder. (Entropía es la tendencia general del universo hacia la muerte y el desorden) James R. Newman
Como entropía se conoce la tendencia natural a la pérdida de orden en un sistema. La palabra, como tal, proviene del griego ἐντροπία (entropía), que literalmente significa ‘vuelta’, aunque hoy en día es empleada en varios sentidos figurados.
El término entropía fue inicialmente acuñado por el físico alemán Rudolf Clausius al observar que, en cualquier proceso irreversible, siempre se iba una pequeña cantidad de energía térmica fuera de la frontera del sistema. A partir de entonces, el término ha sido utilizado en las más variadas disciplinas de conocimiento, como la física, la química, las matemáticas, la astrofísica, la lingüística, la computación o la ecología, para hacer referencia a la medida de desorden a que tiende un sistema.
Así, por ejemplo, en Física, la entropía se refiere al grado de irreversibilidad que, en un sistema termodinámico, es alcanzado después de un proceso que implique la transformación de energía. En Química, por su lado, hace referencia a la entropía observada en la formación de un compuesto químico. En Astrofísica, alude a la entropía observada en los agujeros negros. En teorías de la información, la entropía es el grado de incertidumbre que se tiene en relación con un conjunto de datos. Mientras que, en Informática, hace referencia a la aleatoriedad recogida por un sistema operativo o una aplicación para su uso en criptografía.

La entropía puede interpretarse como una medida de la distribución aleatoria de un sistema. Se dice que un sistema altamente distribuido al azar tiene alta entropía. Un sistema en una condición improbable tendrá una tendencia natural a reorganizarse a una condición más probable (similar a una distribución al azar), reorganización que dará como resultado un aumento de la entropía. La entropía alcanzará un máximo cuando el sistema se acerque al equilibrio, y entonces se alcanzará la configuración de mayor probabilidad.
Una magnitud es una función de estado si, y sólo si, su cambio de valor entre dos estados es independiente del proceso seguido para llegar de un estado a otro. Esa caracterización de función de estado es fundamental a la hora de definir la variación de entropía.
La variación de entropía nos muestra la variación del orden molecular ocurrido en una reacción química. Si el incremento de entropía es positivo, los productos presentan un mayor desorden molecular (mayor entropía) que los reactivos. En cambio, cuando el incremento es negativo, los productos son más ordenados. Hay una relación entre la entropía y la espontaneidad de una reacción química, que viene dada por la energía de Gibbs.

The second law of thermodynamics states that the entropy of an isolated system never decreases. Such systems spontaneously evolve towards thermodynamic equilibrium, the state with maximum entropy. Non-isolated systems may lose entropy, provided their environment's entropy increases by at least that amount so that the total entropy increases. Entropy is a function of the state of the system, so the change in entropy of a system is determined by its initial and final states. In the idealization that a process is reversible, the entropy does not change, while irreversible processes always increase the total entropy.
Because it is determined by the number of random microstates, entropy is related to the amount of additional information needed to specify the exact physical state of a system, given its macroscopic specification. For this reason, it is often said that entropy is an expression of the disorder, or randomness of a system, or of the lack of information about it. The concept of entropy plays a central role in information theory.

This mellow old building is to be torn down, according to the owner. The roof has already caved in, so if the owners don't finish the demolition soon, this winter's snow will.
Thank you for visiting!
The concept of "Entropy" (from the Greek word Entropia (which means turning-toward or transformation)) is based on a principle of thermodynamics which deals with energy.
The word mostly refers to the idea that (when left alone) everything in the universe eventually moves from a state of order to a state of disorder... and that entropy is a measure of that change.
I'm not too sure that I completely agree with that definition of the word. :)
I'm happy to accept that entropy is a measure of change... but I firmly believe that when things are left alone... they will always revert from disorder... back to exactly as they should be!
The crown is etched, but the law is broken.
Glass holds the throne, yet dice defy stillness.
Each dot a decree undone,
each tumble a rebellion in miniature.
This is not a toast—it’s a reckoning.

From the OED: entropy "a state of or tendency towards disorder"
The second law of thermodynamics or entropy, that is disintegration. It happens to us all, we are all heading for the dust and on that happy note we can all look for some interesting scenarios on the things happening all around us. Like this gravestone which could be doing with some attention but from the look of things has been forgotten about and so entropy takes over. On a happier note, being a believer in God I have faith in the resurrection and recreation of mankind and just as the subject of the image can be rescued and restored God can accomplish much greater tasks. There I have got that of my chest and I wish all my fellow photographers a great week with loads of opportunities.

Physicist Sir Arthur Eddington introduced us to The Arrow of Time. As we look into the future we see a universe which is gradually descending into disorder, expanding and cooling, ultimately to become a scattered collection of particles so far separated within an unimaginably vast nothingness that the probability of them ever again combining to create anything is zilch. That is indeed a depressing forecast of our destiny, but as the process will take about 10 trillion years (around 50x the current age of The Universe) there's no need to cancel your pro subs just yet. Conversely if we look into our past we see greater order. Ultimately we could look back to The Big Bang when The Universe was simple and very highly ordered before its unimaginably rapid expansion an instant later.
HMM all - very deep for a Monday! Sir Arthur illustrates The Second Law of Thermodynamics which holds that entropy increases with time. The entropy of a system refers to the amount of order within it. Low entropy describes a high degree of order. For example, if we conceptually reduce your home, that pile of bricks or whatever, into its constituent atoms we can imagine that only a very few arrangements of those atoms would create your home, meaning that your home is a low entropy system. Similarly a pile of beach sand has a high level of disorder, representing high entropy. A pile of sand is a pile of sand - there are very many ways the grains of sand in a pile may be arranged to create any old pile and one pile of sand is pretty much the same as any other. However, if you put some in a bucket then threw it into the air, you would be very surprised if it landed in the form of a sand castle. But it could, proven by you instead flipping the bucket over in traditional seaside fashion, giving it a tap and carefully removing it, creating your sand castle. The grains therefore can make such a thing and could therefore land in just the right places even if you threw them into the air. But there are far many more configurations that they could take (most of which are unremarkable piles) so while a sand castle magically appearing from a load of airborne sand could theoretically happen, it is a vanishingly improbable event. Functionally speaking, the probability of such an event occurring is zero. If you left a formed sand castle alone, you'd see its entropy increase as it decays into an unremarkable high entropy pile of sand. Ultimately it will become just another part of the even higher entropy beach, demonstrating, during your hard earned summer holiday, a university level physics concept. I've never done a university physics course, he hastily clarifies, but I have done some reading on it.
I should say that it has been fairly pointed out to me that this interpretation does depend on one's world view. This is mine. It's a world view which led to the manufacture of transport options to get to beaches, buckets capable of creating sand castles, cameras, the internet and probes heading to the edges of The Solar System and ultimately beyond on precisely predetermined trajectories calculated using physics, so I think it has some evidence to support it. The background of the photo is the Christian creation story, Genesis 1. That's mine too.
In creating the image, I used a plain yellow background created in Photoshop over which I added a layer of a paving stone to provide texture, reducing its opacity to allow the yellow to colour it. Genesis followed, and finally a photo of a small pocket watch which I vandalised through the wonders of Photoshop, using much tiny deleting, moving and transforming, its parts disappearing into the future as it falls into disorder, following The Arrow of Time.
Seen best in nature, entropy is simply a measure of disorder and affects all aspects of our daily lives. In fact, you can think of it as nature's tax. Left unchecked disorder increases over time. Energy disperses, and systems dissolve into chaos. The more disordered something is, the more entropic we consider it.

It's inevitable . . . we all face it . . . and all of our possessions and property . . . even our memories will fade . . . eventually . . .
This is a case where it took extreme measures to extract what I had seen from the photograph that I took . . . this was taken on a dull, gray day . . . and when I tried to punch up the light a bit, the green of the plants and trees took over the shot. When I tried to back down the saturation, it just looked dull, and the structures and the trees were lost as well . . . thank goodness for textures and sepia filters and layers and all that . . . and I salvaged the ghost of this old farm as embodied in that glorious tree on the right. Don't tell me that nobody ever sat under that tree with a tall refreshing drink after an afternoon throwing hay!
