1. Introduction and motivation: are birds smarter than nerds?; 2. Dynamical derivation (and a more conventional one) of the Mermin-Wagner-Hohenberg Theorem; or, why we can't all point the same way; 3. The dynamical Renormalization Group;; or, why we can do physics, illustrated by the KPZ equation; 4. Formulating the hydrodynamic model for flocking; 5. The dynamical renormalization group applied to the flocking problem; 6. Incompressible polar active fluids in the moving phase in dimensions d > 2: the 'canonical' exponents; 7. Heuristic argument for the canonical exponents ('20-20 hindsight handwaving argument'); 8. Incompressible flocks in spatial dimensions d = 2: mapping to the KPZ equation; 9. 'Malthusian' flocks (flocks with birth and death); Bibliography; Index.
