RE: physics
Gahhh! My head hurts too...

Right, I think I've figgered it out.

In a vacuum, an arrow shot backwards at 90MPH from a car doing 90MPH would appear to travel at 90MPH away from a viewer in the car. But to a viewer at the roadside, the arrow would just drop to the ground -- the velocities would cancel each other out.

But add in the air, and the arrow starts with a 90MPH tailwind. So to an observer in the car it would appear to travel away at 180MPH. But a viewer at the roadside would see the arrow travel at 90MPH.

Strewth. Einstein got public acclaim and prizes for this stuff. Where's mine?
