I agree, it's the first time I even started to understand how those particles might work!

Funny thing:
- my grandfather would have suspended physics if he'd said an atom can be divided into smaller parts
- my father would have suspended for that same statement about a proton

Question:
Are there any signs yet that maybe a quark (or electron, or neutrino) might consist of anything even smaller?
Or have we really reached the smallest level there is?
