Entropy exchange

In quantum mechanics, and especially quantum information processing, the entropy exchange of a quantum operation acting on the density matrix of a system is defined as where is the von Neumann entropy of the system and a fictitious purifying auxiliary system after they are operated on by . Here, and where in the above equation acts on leaving unchanged. (Wikipedia).

Entropy is NOT About Disorder

Entropy is often taught as a measure of how disordered or how mixed up a system is, but this definition never really sat right with me. How is "disorder" defined and why is one way of arranging things any more disordered than another? It wasn't until much later in my physics career that I

Entropy production during free expansion of an ideal gas by Subhadip Chakraborti

Abstract: According to the second law, the entropy of an isolated system increases during its evolution from one equilibrium state to another. The free expansion of a gas, on removal of a partition in a box, is an example where we expect to see such an increase of entropy. The constructi

A better description of entropy

I use this stirling engine to explain entropy. Entropy is normally described as a measure of disorder but I don't think that's helpful. Here's a better description. Visit my blog here: http://stevemould.com Follow me on twitter here: http://twitter.com/moulds Buy nerdy maths things here:

Teach Astronomy - Entropy of the Universe

http://www.teachastronomy.com/ The entropy of the universe is a measure of its disorder or chaos. If the laws of thermodynamics apply to the universe as a whole as they do to individual objects or systems within the universe, then the fate of the universe must be to increase in entropy.
