The Stunning link between Entropy time and information

The Stunning link between Entropy time and information

The common interpretation of entropy is that it is a measure of disorder in the universe. The universe is on path to more and more disorder. And this is the reason time is thought to flow forward.Is entropy a fundamental property of nature? Or is there something deeper? Tenet entropy science.

Scottish physicist, James Clerk Maxwell came up with a thought experiment, called Maxwell’s demon, that showed a mechanism where entropy could be reversed. It would violate the 2nd law of thermodynamics. No one could resolve it for over 100 years. But when researchers at IBM solved this paradox, they showed that entropy was related to something even more fundamental – information.

All physical laws appear to be time reversible. The only law of physics which appears to be time irreversible is the law of increasing entropy – the 2nd law of thermodynamics.

Let’s take a container with gas isolated on one side with a barrier. If we remove the barrier, the gas will expand into the full volume of the container. We have just increased the entropy of the gas. The reason there is more disorder is that in a greater volume there are more places that individual gas molecules could be. This greater possible number of arrangements is a better description of entropy.
