Hi everyone, can anyone explain entropy to me please! In simple terms that are readily understood. Kindly note that it is not always helpful to explain a basic concept in terms of further concepts that are equally obscure. The following passage is taken from an article posted on Nassim Haramein’s facebook page tonight:

“The physics that describes the micro-scale ordering of a system is known as entropy, so obviously this is where we must turn. When we talk about entropy, we have to remember that the idea of entropy was derived assuming an isolated or closed system where an increase of entropy is essentially an increase in the amount of “lost” energy. Thermodynamically speaking, the system will be tending towards a state of thermal equilibrium – a state where no more work can be done on the system, unless from external sources – this is the state of maximal entropy.”

I have also recently read a small book by Carlo Rovelli “The Order of Time” where again, the fundamental principles of the book are all based around “Entropy”.

Of course I may be lacking in some basic knowledge of physics but still it does seem to me that a lot of new ideas are arising from the term Entropy - and yet I have to confess I am still not at all sure what exactly Entropy is. Over to you, and thank you.
