The structure of matter


 * Matter and energy
 * Wave-corpuscular dualism
 * Standard Model of particle physics:


 * Basic physical interactions (basic forces in nature, size and range)
 * Particles:
 * Intermediate particles (bosons)


 * Elementary particles of matter (fermions):
 * quarks
 * leptons
 * Composite particles:
 * hadrons:
 * baryons
 * mesons
 * Antiparticles
 * Quasiparticles
