The subatomic world. What is a quantum, anyway? ; Where do the laws of quantum physics hold sway? ; What is the correspondence principle? ; How big is an atom? ; What is inside an atom? ; Why is solid matter solid if it is mostly empty space? -- Digging deeper. How big is a nucleus? What is inside it? ; How big are protons and neutrons? What is inside them? ; What is Planck's constant and what is its significance? ; What is a photon? ; What is the photoelectric effect? ; What particles are believed to be fundamental? What particles are composite? ; What is the standard model? -- The small and the swift.

Names, names, names : What do they all mean? ; What are the properties of quarks? How do they combine? ; What are the composite particles? How many are there? ; Does every particle have to be a fermion or a boson? What sets these two classes apart? ; What is a Bose-Einstein condensate? ; How did bosons and fermions get their names? -- Interactions. What is a Feynman diagram? ; What are the essential features of Feynman diagrams? ; How do Feynman diagrams illustrate the strong, weak, and electromagnetic interactions? ; Which particles are stable? Which are unstable? What does it mean to say that a particle decays? ; What is scattering? ; What is the same before and after a scattering or a decay? ; What changes during a scattering or decay? -- Constancy during change.
