  1. The hottest thing on Earth (T=300 MeV=310^8 ev) and the coolest, (T=10 nK or 10^(-12) eV) both create near-perfect liquids and (elliptic) little Bangs ! • Quark-Gluon Plasma at RICH is rater stronly coupled and has surprisingly small viscosity /(hbar s)=.1-.2<<1(the estimate of D.Teaney,2004) • Elliptic flow of ultracold trapped Li6 atoms in a=> infinity regime. It has a ``quantum viscosity” /(hbar n)=.3(derived from 2 modes of oscillations B.Gelman, ESuryak,I.Zahed nucl-th/0410067) • A gift by the string theorists: AdS/CFT correspondence allows to calculate viscosity of infinitely stronly coupledN=4 SUSY YM , g^2 N_c -> infty (D.Son et al , 1993) /(hbar s)=1/(4Pi)

  2. Sonic boom from quenched jets Casalderrey, Shuryak,Teaney, hep-ph/0410067; • the energy deposited by jets into liquid-like strongly coupled QGP must go into conical shock waves at Mach angle: seems to be observed at RHIC (data from PENIX on angular distribution relative to trigger jet in the transverse azimuthal angle)
