Degrees of freedom, structure, order parameters, correlation functions, susceptibility, scaling.
Phase averages vs space averages, what scale-free correlations look like in real life, data from flocks and swarms, orientation vs speed correlations.
Goldstone mechanism, massless modes, transverse vs longitudinal susceptibility, the problem of the modulus, what is due to math and what is due to biology?
The paradox of sound, are scale-free correlations necessary for information propagation? How to escape the falcon, necessary vs sufficient conditions for information transfer.
Ferromagnets on the move, Vicsek model, first or second order differential equation? Toner-Tu field theory, first sound propagation.
The trap of the over-damped limit, finite-size transients matter, symmetries and their generators, second sound propagation, dispersion relations in models and experiments, finite-size inertial crossover.
Mode-coupling models at equilibrium, why are we talking about liquid Helium? The dynamical critical exponent, finite-size RG crossover and the relevance of unstable fixed points, going off-equilibrium.
A light yet exhilarating lecture about everything else.
