    Work during free expansion of a gas

    fair enough - I was not going to reply to this but I guess I will try again. Now I must state that the following has little to do with the concept of work as currently taught. Hence should be judged accordingtly. To me work has to be done onto something. Therefore, we must define the...

    Black hole versus 2nd law of thermaldynamics

    I appreciate that your ideas are following the old KISS principle. Which is grand. And although I am only a casual reader of this tsuff, I am not thrilled with some of the quantum arguments, nor Hawkins radiation. But when you argue time goes backwards, are you not also basing it on...

    Why is the Second Law of Thermodynamics Empirical?

    God I know what my gut tells me about the second law, it is just that I am not fully armed to take it down yet. No matter I will answer you in part. To me the second law is a result of our thermodynamic perspective. I started a new thread so go read it if you care to and if so thanks. And yes...

    Black hole versus 2nd law of thermaldynamics

    thanks for the quick reminder However to me herein lay an example of an inherent problem in physics. You say that the simple does not apply, and perhaps you are right. Me I doubt it. Things in this world are simple, heck even in black holes. When you decide to take a prolonged complicated...

    Why is the Second Law of Thermodynamics Empirical?

    come on folks - cold air is denser than warm air, and that drives convection. Also conduction exists but it is minor anyhow do not be fooled, heat flows from cold to hot and from hot to cold. What? Yup. It is just that the net flow of heat is generally from hot to cold

    Black hole versus 2nd law of thermaldynamics

    there is perhaps something else to consider to ponder, and yes what I say is controversial. TdS=dE+PdV is the most common type of entropy change (dS) If you consider that a black hole is an isometric horizon (dV=0) into which matter and energy stream into, then you may ask yourself, should...
