Point me to where it says that. In the original post, please.

He said:

"what happens if you flick the extreme of a pencil, in space".

And in a later clarification:

Either the eraser end or the tip of the pencil

Looking back at it, I realize that I did assume that the "flick" wasn't aimed down the length of the pencil, but I think that's a reasonable assumption.

The answer is that lift is actually generated mostly by the angle of attack (air hitting the underside of the wing, pushing the plane up). Bernoulli's principle usually helps, though. Stunt planes that are designed to regularly fly upside down often have symmetric airfoils and don't use Bernoulli's principle at all.

Correct. The correct answer is that the pencil will start spinning *and* moving away from you. And you will start moving away from the pencil, although much more slowly, since you weigh so much more. You'll probably start slowly spinning as well, depending on where the vector of the flick was in relation to your center of gravity.

Some of those are in here. Shaving and gardening I don't see, but there is Technical-->Kitchen. And there is Technical-->Wheel vehicule[sic] handling-->Land vehicles-->Car driving. Which is then helpfully subclassified into Volvo, Ford, Chrysler, General Motors and Subaru, because of course you have to retrain before you change car brands. And the world's largest car manufacturer (Toyota) doesn't rate a mention.

I Robot had nothing to do with the book. It was in fact written on another title first and then they bought the name to slap on it because people would recognize it, and, hey, it's about robots, right? A bit of script touch-up to change a few names (gotta have Susan Calvin, although of course she won't be plain) and put in a few references to Asimov's concepts, and we're done!
