  I said "heat, by itself", not just "heat". And I stand by what I said. It is fundamentally correct. The state of entropy of the an isolated system will always increase over time. Yes, you can bring in other things, like an outside system or additional useable energy, but that only disproves the misquoted version of my statement.
