Scanning fundamental particles

Down and down, finer and finer, more and more absolute your Analysis went. Past molecules, past atoms, all the way down to individual protons, neutrons, and electrons. You watched as each particle spun, tracked the erratic movements of an electron around its atomic nucleus, and dug deeper. And you found...quarks. Quarks, Gluons, Leptons, and other particles. You didn't even know they were called Quarks, Gluons, Leptons, and various other particles. You wouldn't know that for years or even decades, actually. At this point though, you think this is about as refined as is possible to get with material Structural Analysis. (Can now scan the fundamental particles of fundamental particles! Why would you even need to scan this deeply?)
