book_cover_big.gifThere  are numerous definitions for what entropy is. I will in the coming weeks discuss a few but will give already a popularized version below.

Entropy is a measure for the quality of energy. The quality of energy is reflected in the amount of work that a certain quantity of energy can produce. When the quality is high then the entropy value is low, when the quality of the energy is low then the value of the entropy is high.

More in the weeks to come.
