brian, you have been suckered. that was not derek rowell professor of stress
analysis in Mech Eng, but rather someone pretending to be him. NO professor at
MIT would write what that clown wrote. None. He would be laughed at the rest
of the staff, and some disgruntled student would report him to the president
for disciplinary action. Who would pay money to "learn" something that is
known so wrong by the entire staff?

oops! He's a professor there!


Not surprising that he's offering an opinion on fluid dynamics.
While supersonic flow is studied more by aero engineers these
days, slow speed fluid flow is the province of mechanical engineers.

Take a look at "Fluid Mechanics" Fogiel/Cimbala
for an example.
Cimbala is Prof of Mech Eng at Penn State.
