Numbers to plan, make, maintain - illustrated on desktop

From Yinka Shonibare March-October 2022 exhibition - Enlightenment

This exhibition embodies in visual form so many themes, such as the Batik origins of Indonesia for the fabric dyed with patterns using wax, later industrialized and commodified for international sales by the Dutch and most beloved among buyers of West Africa. The mannequin has one arm of wood to represent the historical figure of this woman polymath who was known to have an artificial limb. The quill and ink are reminders of literacy and distant or local communication across space but also across time. And the figures on the page show the purpose and power of calculation using numbers and measurement. But for the purpose of this article, it is not the many sides of the artwork to focus on, but instead to think about the functions and powers of math and its applied form in engineering.

A person with training and who has wide and deep experience of designing structures of the built landscape, or to make objects of beauty, including tools, weapons, vehicles, containers, machinery, and so on is able to translate an idea into specific lines, angles, and curves that takes visual form on paper (or digitally these days, thanks to automatic measurement and calculation from CAD, computer-aided design) to communicate instructions to others who will make use of the measurements, but also to communicate this visible record to others implicated in the creation (suppliers, financers, future maintenance and repair experts) and those not yet born who may research the matter in years to come.

Looking at the function and use of such drawings that make possible large and small projects shows its power. But by considering the absence of these drawings, it is also possible to appreciate the value of this visual and numerical technology. Large public works from the ancient world were successfully erected using limited mathematics and record-keeping, and some of them exist still today in full or as trace ruins. Obviously, no CAD was involved, but some form of recording measurements, supplies ordered and materials received was necessary, since the scale and degree of detail was too much for any one person to hold reliably in his or her head alone. In the complete absence of design plans, measurements, and calculations the biggest project would surely be limited: earthen pyramids, stone barrows for burials and other rituals, river weirs to direct migrating fish into traps are examples of biggest limits for design solutions to problems posed when the precision and mathematics illustrated in this photo do not exist.

The words 'accounting' (tracking of numbers) and 'accountability' (responsible for one's actions or inactions) clearly are related. And while one is more literal (records of income and out-go) and the other is more figurative (of one's title, authority, expectation, liability) there is clearly a shared forensic element of measuring results against a standard, an existing record, or a point of reference. Looking, again, at the above photo, it is easy to imagine the use of plans to accomplish a project that meets the stated measurements.  But in a larger sense, too, there is a kind of gestalt or way of seeing the world for a person who is accustomed to measuring resources and accounting for them. Colonial governors, military officers, and corporate managers all rely on record-keeping and numbers more generally, not just to accomplish the stated plan, but then also to maintain that finished plan in good working condition so it is fully operational; or if less than fully working, then studying the plans to discover what changes to make in order to resume the full functionality as envisioned and designed.

Although this picture is part of an exhibition piece from the Nigerian-British artist, Yinka Shonibare, it also illustrates this peculiar development in social life of using numbers and mathematical manipulation to engage with countrymen and foreigners. It is a kind of language that expands and amplifies the verbal kind of language that comprises social life.
