A Sharp Straight Edge over the Dwingeloo Veldt

Submitter: Jan Noordam
Description: Nature is famously fuzzy, with few sharp edges or straight lines(*). So where does this razor-sharp and mathematically straight line come from? Even Minnaert(**) is silent on this subject.

(*) One of the rare exceptions is galactic polarization, of course.
(**) Marcel Minnaert "De natuurkunde van 't vrije veld" (1937-1942)
