What does the concept of entropy mean?
In: 96
I think Brian Cox has good explanation in one of his shows.
If you build a sand castle is a desert it as highly ordered structure (low entropy) but over time it will revert back to just grains of sand (high entropy).
However over the the time the desert has existed the sand has never been randomly arranged as a sand castle. It is not impossible just very unlikely that would happen because naturally thing seems to go from low to high entropy.
