Exact excerpt
The basic blowup mechanism in the averaged equation is that of a von Neumann machine, or more precisely a construct (built within the laws of the inviscid evolution) that, after some time delay, manages to suddenly create a replica of itself at a finer scale and to largely erase its original instantiation in the process. In principle, such a von Neumann machine could also be built out of the laws of the inviscid form of the Navier-Stokes equations (i.e. the Euler equations).
