[Paddlewise] Paddling in Space

I'm not sure but, I think the comparison of "rockets" and "paddles" may be
apples to oranges, as they say. A rocket engine does not push against anything
except the rocket body and that is why it can operate with, or without an
atmosphere, or, even in water. A paddle must have something to push against
(more like a jet engine than a rocket), to be effective. I know this is a
small point but it's raining here in MN today and I can't go paddling.
