I’m responding to Mike Fuselier’s letter to the editor of Aug. 8. I see that he is an educator.
I only hope he doesn’t teach science because he certainly doesn’t understand the laws of thermodynamics. He states a half-baked version of the Second Law to defend his diatribe against evolution.
A more-complete statement of the Second Law is that the entropy (disorder) of a closed system increases. The key word here is closed. The entropy of the Earth can actually decrease if it is receiving energy from the outside, like from the sun.
The Earth is not a closed system. The universe is. The Second Law does not stand in the way of evolution. Fuselier also seems to confuse theory and fact.
A theory is an explanation, and evolution is the best explanation we have so far because it is testable, and it has withstood the test of time in spite of what Fuselier might want to believe. Testability is the hallmark of science. Before one starts invoking the laws of physics, I would suggest he understand them first.
