In any case, no harm, no foul.
I can't believe that you, a PhD mathematician, is discussing high school physics and chemistry.
Why not? I can also discuss algebra and arithmetic if the discussion calls for it.
One aspect that I was attempting to point out is the fact that air has considerably more mass than many people suspect. I know I was surprised the first time I learned that a cubic meter of air has a mass of about 3 pounds.
