Editor's Note:

In a previous post, Louis thinks he may have confused the First Law of Motion for the First Law of Thermodynamics.

The first law of motion states, 'for every action there will be an opposite and equal reaction.'

The first law of thermodynamics states, 'if you place two bodies of unequal temperature together, the heat will flow from the one with the highest temperature to the one of lower temperature until the two bodies are in equilibrium.'

The lesson is a simple one: why rely on memory when it is so easy to check the facts?

Louis had the law right but the name wrong! Yet this could so easily have been caught.

We regret any inconvenience. If Louis can remember which post that was...we could go and fix it. Louis says he has fixed it.

Sorry about all that. Never mind. -ed.
