Men From Venus Invade Earth - Part 2

Now, here's the sad part.  The Men From Venus (mfv) were raised with completely different physics from Earth.  It's all to do with the Rayleigh Number (rn).   This definition describes convection, which is great, but it is also the boundary between laminar and turbulent flow.  A low rn means heat is transferred by conduction and a high means convection.

Venus is extremely low in rn.  The highly compressed atmosphere acts as a greenhouse glass, and Venus is very hot because of it.  Low rn has a different physics, for example insects live with low rn in air.  You can't use their method of flying with an airplane at high rn.  The whole thing is quite amazing and you should read about it.

Unfortunately, mfv did not read about it, and took a low rn environment and applied it to Earth.  They took over the unfortunate group and said "We don't need any of that experiment stuff, we can get everything from satellites."  They killed the experiment people, but those guys did one great thing before they died.  Magnificent.

The mfv looked for atmospheric contaminants that could do stuff.  They discovered the ozone hole with satellites, and came out with a Venus-like explanation -- Chlorine was the villain, even at a few parts per million.  That's Venus Physics!
