Teachers' strike and physics

[isil_helyanwe]

There's a teachers' strike tomorrow. Unfortunately, my year still has to come into school 'cause we're taking important exams. Bah. Planning on standing in the foyer and shouting, "Scab! Scab! Scab!" at any teachers that cross the picket line. Not that there really will be a picket line. But we've been told not to bug the teachers asking about it, and that they can't express their own opinion because the union told them to do it. Which so means that there have been arguments in the staff room about this.

I have a question for anyone who's good at physics:

You know how the air is full of particles that are quite spread out? Well... what's in between them? And what's inbetween the electron and the nucleus of an atom? Is it all really small pockets of vacuum? Seriously, what's in between atoms?
