The whole governing equation of aerodynamics, the famous Navier-Stokes equation, is just a different representation of our well known F=ma. By the way, is it a miracle (...)

Now *that* would look cool, if it was the first time you'd looked up in a few days. Plus, the apparent gravity on the earth's surface (...)

You said in the last letter before this letter that some liquids (referring to the reaction to friction of certain particles in outer space) are viscious while some solids are very hard and smooth in reaction to friction in outer space.

Newton says you're deflecting air downwards. Aerodynamics says a lot (...) (23 years ago, 29-Jun-01, to lugnet.space, lugnet.off-topic.geek)
