PREFACE 1. WHAT IS AN ELEMENTARY PARTICLE Questions that may not have Answers Something Unchanging Is It Real? 2. QUARKS AND LEPTONS The Quark — The Unconventional Elementary Particle that has not been Found Heavy Particles, Light Particles, In-between Particles What is the "Size" of a Particle? Things to be Learned from Scattering Experiments 3. LOOKING FOR QUARKS Structure of Protons and Neutrons Looking for Fractionally Charged Particles 4. VARIOUS ACCELERATORS Profundity of Nature — Stronger Blows Produce Deeper Resonances The Principle of the Accelerator Colliding Beams — The Power of the Counterpunch 5. THE BIRTH OF THE YUKAWA THEORY From the Atom to the Nucleus Yukawa's Meson Theory Relativistic Quantum Mechanics The Ideas that Led to the Mesons The 1930's 6. THE APPEARANCE OF NEW PARTICLES Coulomb Form and Yukawa Form The π-Meson From Two-Meson Theory to the Discovery of the Muon The Dramatic Apperance of the V Particle Trying Everything 7. ORDERLINESS OF ELEMENTARY PARTICLES AND CONSERVATION LAWS The Gell-Mann-Nakano-Nishijima Law The Key to an Idea Strong Interactions and the Conservation of Isospin The 3-3 Resonance of the Pion and the Nucleon 8. PARITY AND CONSERVATION What is Parity? The Non-Conservation of Parity CP Violation Are Natural Laws Invariant under Time Reversal? 9. COMPOSITE MODELS OF HADRONS What is Expected from Fundamental Particles The Composite Model of Fermi and Yang The "Elementary" and "Compound" in the World of Elementary Particle Physics The Sakata Model 10. THE QUARK MODEL How does the Quark Model Differ from the Sakata Model? Baryons in the Quark Model The Discovery of the Ω as Predicted 11. EVOLUTION OF THE QUARK MODEL Making Quark Compounds
Analogy with Nuclei Quarks Come in Colors and Flavors The Nine Quark Model Are there Colored Hadrons? The Possibility of Integer Charged Quark The Unexpected New Particle J/Ψ 12. CHARM AND ITS FOLLOWERS The J/Ψ Indicates Profundity of Nature The True Identity of the J/Ψ Particle The Fourth Quark c That Completed the Quark Model Outdone by Nature Again At Least 6 Leptons and at Least 5 Quarks 13. QUARKS WITH STRINGS ATTACHED A Paradox String Model of Hadrons What is a String? 14. WHAT IS A PARTON? Hadrons are Soft Infinitely Small Point Particle Feynman's Parton Model Comparison with the Quark Model 15. TOMONAGA'S RENORMALIZATION THEORY Particle Physics is Busy Chasing New Phenomena Quantum Electrodynamics Infinite Self-energy Renormalization Theory — An Act of Giving Up Something 16. QCD — THE QUANTUM MECHANICS OF COLOR From Meson Theory to Color Dynamics What is A Gauge Field? The Dynamics of Color The Gluon — The Glue to Hold the Quarks Together Asymptotic Freedom Wilson's Lattice Theory 17. SPONTANEOUS BREAKING OF SYMMETRY What is Symmetry? Spontaneously Broken Symmetry The Relics of Spontaneous Symmetry Breaking Superconductivity The Origin of the Quark Mass 18. THE LEANING STRUCTURE OF THE WEAK INTERACTION God's Mistake? What is the Weak Interaction? Orderliness in the Weak Interaction There must be a Charmed Quark 19. THE WEINBERG-SALAM THEORY Beyond the Yukawa Meson Theory The W Boson The Unification of Weak and Electromagnetic Forces Comparison with the Superconductivity 20. THE UNIFIED FIELD THEORY
Unification of the Three Forces Incredible Energy — But We Can't Say It's Nonsense Einstein's Unfulfilled Dream The Unification of Three Forces and the Unification of Particles 21. PROGRAM FOR GRAND UNIFICATION The Last Question The Unification Theory of Georgi and Glashow Are There Particles at Lower Levels than Quarks and Leptons? An Astonishing Conclusion — All Matter is Unstable The Coming Together of Particle Theory and Cosmology The Mystery of Man Who Divines Matter and Universe in an Instant GLOSSARY INDEX
