That's the secret diagram for going directly down wind faster than the
wind!!!!!


I think http://xkcd.com/619/ is quite apt and not related.

Well, I looked at the home page ("airfoil") on that site and just
found out the school description of how wings work (faster air over
the top so less pressure, and the air must join back up at the far
side) is actually wrong (or at least vastly over simplified).
I never thought to question it. But then, how does an aircraft fly
upside down? No idea why that question never popped into anyones heads
at school !

At bit like A-level chemistry. I soon gave up trying to understand a
few things from first principles, since you came to a different answer
than the text book. I thought I was being thick, and it turned out I
was the genius after all !

Dont go there.

It transpires that actually the Bernoulli equations are for inviscid
fluids and wings would never work in inviscid gases.

I do more or less understand the issues, but do you REALLY want to?

Yep.

I remember physics..'all motion is relative'...Ok..I thought. No. It
can't be

'Sir?' '..yes boy?' 'If all motion is relative, and I spin round and my
arms fly out and I get dizzy, what am I spinning relative TO?'
Very long silence.

'The integral of the fixed mass of the rest of the Universe'.

******* had a PHD in atomic physics so never likely to catch him out,
but that was the longest he ever took to answer..
