3. Matter fields, of an uncommon self-avoiding kind -- 3.1. The need for new unusual anti-commuting numbers -- 3.2. Matter quanta. An interlude -- 3.3. Matter fields -- 3.4. Supersymmetry -- 3.5. The love affair with anticommuting numbers -- 3.6
4. Whatever is happening makes an action -- 4.1. The action and the motion -- 4.2. The action of the fields -- 4.3. Action in quantum field theory -- 4.4. Time is real but it helps treating it as imaginary -- 4.5. Bibliography
5. The vacuum : the stage of the fields' play -- 5.1. A metaphysical vacuum? -- 5.2. Feynman graphs -- 5.3. The vacuum has a physical content, to be seen -- 5.4. Bibliography
6. The symmetric shape of the action -- 6.1. Are there other fields in nature? -- 6.2. Symmetry and invariance : the gauge invariance -- 6.3. Other kinds of gauge invariance -- 6.4. Why gauge invariance -- 6.5. The mass looks forbidden by gauge
7. Everything fluctuates -- 7.1. Violating energy conservation? -- 7.2. Picturing by Feynman graphs -- 7.3. Sometimes the quantum corrections are a bit too large, actually infinite -- 7.4. The coupling constant runs like Achilles' tortoise -- 7.
8. The vacuum is not empty -- 8.1. The Higgs field fills the vacuum -- 8.2. The fields are never at rest -- 8.3. Quanta are created and annihilated in the vacuum -- 8.4. (Exact) supersymmetry implies zero vacuum energy -- 8.5. The vacuum energy
9. What else? -- 9.1. A theory of never free quarks? -- 9.2. QFT in a gravitationally curved spacetime -- 9.3. Gravity can describe QFT without gravity -- 9.4. Other topics that are not covered -- 9.5. Bibliography
10. QFT : what for? -- 10.1. The answer is : knowledge -- 10.2. A layer of effective theories -- 10.3. QFT in the Universe -- 10.4. The main web-reference for a farewell -- Appendix. Notes for further insight.
