GR translation: shearing alongside for miles

[Monte Davis]

​Closest to "wind shear" in meteorology or aviation: notional layers of a
fluid (gas or liquid) moving adjacent to each other at different
velocities, with momentum transferred more or less smoothly between them at
the interface -- turbulence arises (i.e. the layers mix and tangle into
vortices) if the velocity difference is too great. (For me, this also harks
back to Achtfaden & co. and the "boundary layer" at the skin of an A4 as it
moves through the air.) The same applies to convection currents in a heated
cauldron: look at a patch of oil or fat sliding across the surface.

I may be stretching here, but I wouldn't put it past P. to have in mind
that the whole picture of successive sliding layers -- foundation of
aerodynamics for  decades before 1945 -- is a *fiction* for mathematical
tractability, the reality being uncountable gas molecules moving with all
speeds and velocities in all directions, the layers emerging only as
statistics. Maybe there's a hint that the tribal/ethnic labels are also
fictions? That after their near-death experience as victims of abstraction
and systematization, the "Czechs" and "Slovaks" streaming along side by
side might be better off as individual I and Thou?

Anyway... look back to your Peenemunde passages, and if possible translate
"shearing" with a technical flavor, maybe whatever a Chinese weather
forecaster uses for "wind shear"
