THE MAPS WITHIN this book should be seen as an aid to memory, rather than a detailed representation of particle physics. There is a rough direction of increasing energy (and decreasing size) from west to east, and increasing complexity from south to north, but there are grey areas and ambiguities. Sometimes the energy scale is binding energy, sometimes mass, and there are unavoidable inconsistencies even so. For example, the photon belongs on Bosonia in the east, even though its presence is felt far to the west. The tau and muon should arguably be further east than the up, down and strange, based on their masses, although one does really have to cross Lamdba QCD to get to the quarks. Allegory and analogy can help understanding, but are misleading if pushed too far. Enjoy yourself but tread with care.
