some issues re motion:
when you access the Internet, what moves?
why did animals not evolve wheels? (Jared Diamond wrote on this long ago)
what are practical (but possibly "far-out") ways to reduce the global warming effect of human motions across the planet?
do electrons move in orbits in atoms? if so, do they use energy?
How and why do continents move/
do ideas or societies have ways of moving that can't be described by physics/
