The existence of God

[Jehanne]

For example, a small spark can serve to detonate a large explosion.

I suspect this guy does not believe in exothermic reactions in general.

Reminds me of a chemistry presentation that I went to with my young daughter given at a local 4-year college. A young college chemistry student had given a nice demonstration to me and my daughter and then politely asked, "Do you have any questions?" Being the mischievous individual that I am, I asked her, "This reaction, is it exothermic or endothermic?" Her professor was standing nearby and gave her womanly, "How dare you!" look at me. The poor young girl just froze, as if I had hit the pause button on a VHS tape, and finally smiled, saying "Neither". I smiled back, thanking her for her presentation, and walked to the next booth while wondering how a chemical reaction that generates light could involve no heat??? (Hmmm.)
