Precision
In her review of "Tracks On The Ocean" by Sara Caputo - Times Literary Supplement, November 15th. 2024 - Christina Thompson alludes to the imprecision of precision itself, which is fair comment. We can achieve extraordinary levels of precision within a given context, as anyone who has had access to a metrology lab and metrologists - myself included - can attest. However, it really is all relative: one person's exactitude is another's ballpark, depending on the terms of reference applied. Context is everything. A woodworker will need precision down to no more than a few hundredths of an inch at the very most, whereas a few thousands of an inch may be too large a margin of error for a an engineer working in metal. To a physicist, nanometre tolerances and measurement will be the order of the day; but even then, the subdivisions of nicety will continue down the rabbit hole into the realms of the subatomic. The fact is that absolute exactitude can never be attained: as wi
