What is the entropy and how to fight it Bashny.Net

Take collected Rubik's cube and start randomly rotated his face. After a few turns, he will be completely dismantled.

Now continue randomly rotated face of the cube as long as he did not meet back.
Pretty soon you will realize that nothing you do not get, but do not worry: you have not collected the Rubik's Cube, but it illustrated the second law of thermodynamics:

The entropy of an isolated system can not decrease.





The heroine of the film Woody Allen's Whatever Works provides a definition of entropy: this is because of what hard shove back into the tube of toothpaste. It is still interesting explains the Heisenberg uncertainty principle, one more reason to see the movie.

Entropy - a measure of disorder, chaos. You have invited friends to the New Year party, tidied, washed the floor, spread out on a table appetizer, drinks were placed. In short, everything streamlined and eliminated as much chaos as they could. It is a system with a small entropy.

You all probably imagine what happens to the apartment when the party was a success: total chaos. But in the morning you have the disposal system with high entropy.

In order to bring the apartment in order, it is necessary to clean up, that is, spend a lot of energy. The entropy of the system has decreased, but there is no contradiction with the second law of thermodynamics is not - you added energy from the outside, and this system is not isolated.

One option doomsday - heat death of the universe due to the second law of thermodynamics. The entropy of the universe reaches its maximum, and nothing in it longer will not occur.

In general, the sound is pretty dull: in nature, all things are ordered to seek the destruction, chaos. But how then life on Earth? All living organisms are incredibly complex and orderly and somehow my whole life fighting entropy (although in the end she always wins).

Everything is very simple. Living organisms in the process of life around you redistribute the entropy, that is, given its entropy around what they can. For example, when we eat a sandwich, then a nice ordered bread and butter, we turn what we know. It turns out that its entropy, we have given a sandwich and a total entropy of the system has not diminished.

And if you take the Earth as a whole, it is generally not a closed system: the sun provides us with the energy to fight entropy.
