Thanked: 346I think he meant "Mars". Mars was the Roman god with the red face. If you saw the HBO series "Rome", in the episode where G. Julius had his triumph, the reason he had a red-painted face is because he was dressed as Mars.

Nope.
Jupiter is famous for its red spot.
It is an immense hurricane, with wind speeds of hunderds of kilometers per hour.

its diameter is almost twice the size of earth. it has existed for a long time, and thermodynamic models have predicted that it will exist for a long time to come.
EDIT: the models are actually a combination of fluidodynamics and thermodynamics, and if I remember correctly, it involves a 4th order partial differential equation with several variables.
For those who don't know what the last sentence meant: most earthly problems can be expressed as only second order equations. And even those are notoriously difficult to solve unless they can be simplified to a couple of standard models for which analytical solutions exist.
A reallife 4th order partial differential equation with multiple variables cannot be solved, except numerically with $$$ number crunchers. And as if that is not enough, the equations usually have emergent chaotic behavior, meaning that very tiny changes can have very serious consequences.
This is why fluidodynamics is about the hardest engineering discipline there is.
Incidentally, this is also why the weather forecast is an unreliable science at best.Last edited by Bruno; 05-08-2007 at 08:50 PM. Reason: Geeking out

Thanked: 1Probably some kids with laser pointers. Make sure the bathroom window shade is closed.
