Why did men's pants move down from the "natural waist" to the hips? | At a guess I would say it started as a functional change.

WTF is the number after classes in the US? Informatics 101, etc. | This doesn't seen to be standard, though.

Can really small things be drastically affected by the surface gravity of the human body? | Other comments mention that gravity is weak.

The first stage of the Saturn V rocket has 5 engines. Why didn't they use 1 much larger engine as opposed to 5 relatively smaller engines? | It's unclear if that was even doable then, or now; besides from any issues outlined by others.
