Funnies
If 13 blondes stand abreast, ear-to-ear, what is this? ... a windtunnel.
And if they raise their hands, what is this? ... a massively idling parallel computer with 12 vector units.
(One is cache.)
If a brunette puts her hands over her ears, what she does? ... trying to prevent thought flow.
If you look a fluid-dynamics lecturer in the eyes, what can you see? ... cavity flow.
What is an "incompressible investigator"?
One that can take pressure without dilating.
I am not exactly a rocket engineer.
(I am also doing work in aeronautics).
Once you get rid of integrity the rest is a piece of cake.
(It will be far more than a piece.)
Don't cakes ruin your teeth?
The early bird catches the worm. But: The second rat gets the cheese.
Übrigens:
Wenn Sie eine Stelle im ingenieurwissenschaftlichen Bereich der baden-württembergischen Universitäten entdecken,
wo die geforderte national und international leuchtende und transparent zu erbringende Lehr- und Forschungsleistung angemessen bezahlt wird, dann ...
... haben Sie geträumt.
Mir sparet au da.

Truth
Caution: This page may contain traces of facts.
Zwei Dinge sind unendlich, das Universum und die menschliche Arroganz. Aber beim Universum bin ich mir nicht ganz sicher.
Two things are unbounded: the universe and human arrogance. But as for the universe, I am not quite sure.
