Relaxation and condensation of an isolated low-energy Bose gas provide an ideal setting for the study of universal features of far-from-equilibrium many-body dynamics and the emergence of long-range order, still open problems that are relevant from subnuclear to cosmological lengthscales.

In this colloquium, I will give an overview of our recent experiments on the emergence of order in homogeneous Bose gases, produced in optical box traps. Using complementary experimental probes, we have developed a comprehensive picture that connects different theoretical points of view, including the modern theory of nonthermal fixed points and the traditional theories of turbulence [1-4].
