Shape is as important as size: roundness and the science of measurement
journal contribution
posted on 2014-09-18, 08:39 authored by Chris SangwinScience relies on standards for measurement. This article describes assessment of
geometric shape, rather than size. We consider the problem of establishing departure
from roundness. In doing this we examine some curious geometric shapes, including
non-circular shapes of constantwidth and shapeswhich rotate smoothly inside triangles.
This has led to the recent reassessment of the standard testing procedures using veeblocks.
