Simply pouring energy at a system doesn’t automatically decrease entropy. Work needs to be done and energy is used in that. So what is it that is causing the work to be done? What is life? Why does it get to sometimes violate the 2nd law?

You have got to be kidding! The post I cited was honored with it's award for a reason. Are you trying for the 2007 award?

Lets try an analogy. You admitted to a degree in meteorology or some such.

Where does the energy that creates weather systems, tornadoes, hurricanes and the like, come from?

With entropy as the guiding principle, they should not be able to form. They should violate the second law of thermodynamics just as you claim life does. Everything should be headed downhill!

But that's not correct! Entropy works on a large scale, allowing local events, such as hurricanes and life, to go in the opposite direction for a time, while the overall system follows the 2nd law.

I can't believe you don't understand this! This is basic science, not even grad level stuff.

Your failure in understanding here is because you fail to understand the 2nd law. Period. Net entropy is always greater than or equal to zero. Always.

Look up the Gibbs Free Energy equation. Once you understand this equation and how chemical processes spontaneously or non-spontaneously work, then you will have a much better understanding of thermodynamics and will probably stop making such embarrassing errors.

I hate to be a nit picker because I now what you mean. But in physics, work = energy. I use the term "directed energy" which implies intelligence.
