“If someone separated the art of counting and measuring and weighing from all the other arts, what was left of each (of the others) would be, so to speak, insignificant”*…
Mathematics, Bo Malmberg and Hannes Malmberg argue, was the cornerstone of the Industrial Revolution. A new paradigm of measurement and calculation, more than scientific discovery, built industry, modernity, and the world we inhabit today…
In school, you might have heard that the Industrial Revolution was preceded by the Scientific Revolution, when Newton uncovered the mechanical laws underlying motion and Galileo learned the true shape of the cosmos. Armed with this newfound knowledge and the scientific method, the inventors of the Industrial Revolution created machines – from watches to steam engines – that would change everything.
But was science really the key? Most of the significant inventions of the Industrial Revolution were not undergirded by a deep scientific understanding, and their inventors were not scientists.
The standard chronology ignores many of the important events of the previous 500 years. Widespread trade expanded throughout Europe. Artists began using linear perspective and mathematicians learned to use derivatives. Financiers started joint stock corporations and ships navigated the open seas. Fiscally powerful states were conducting warfare on a global scale.
There is an intellectual thread that runs through all of these advances: measurement and calculation. Geometric calculations led to breakthroughs in painting, astronomy, cartography, surveying, and physics. The introduction of mathematics in human affairs led to advancements in accounting, finance, fiscal affairs, demography, and economics – a kind of social mathematics. All reflect an underlying ‘calculating paradigm’ – the idea that measurement, calculation, and mathematics can be successfully applied to virtually every domain. This paradigm spread across Europe through education, which we can observe by the proliferation of mathematics textbooks and schools. It was this paradigm, more than science itself, that drove progress. It was this mathematical revolution that created modernity…

As we muse on measurement, we might recall that it was on this date in 1790, early in the French Revolution, that the French Assembly, acting on the urging of Bishop Charles Maurice de Talleyrand, moved to create a new system of weights and measures based on natural units– what we now know as the metric system.
“The metric system did not really catch on in the States, unless you count the increasing popularity of the nine-millimeter bullet”*…
Nearly everywhere in the world, folks use the metric system to measure things; here in the U.S. we use the Imperial system. (Note that Britain should really be a dark shade of green– i.e. a little yellow, mixed with a lot of blue. Brits may regularly use inches, ounces, miles, and pounds in everyday life, but have officially been Metric since 1965.)
Mike Sowden (amusingly and informatively) recounts the history of the metric system, then muses on why Imperial measures– the mile, the inch, the cubit, the ell– have staying power…
… Yes, all of these lack precision, so they’re useless for modern science, and would be incredibly dangerous if used for engineering purposes. But they also tell a story of people’s relationship with the space they moved through.
A lexis of movement – perhaps in a similar fashion to the language of landscape that writer Robert MacFarlane has done so much to retrieve.
This is why I’m on the fence about Imperial now. There’s no question that Metric is necessary as a standardised, exact form used to make cars that don’t shake themselves to bits, planes that don’t fall out the sky and spacecraft that can launch themselves to interplanetary targets with mind-blowing accuracy.
But the versions of Imperial still being used by people in everyday life deserve their place in the world too.
Anyone brought up thinking and feeling temperature in Fahrenheit can tell us Celsius-reared folk something different about how we can experience the world. Anyone cooking in pounds will be thinking about food a little differently (“well, it’s just 2 cups, isn’t it?”). All these things are tiny windows into new ways of seeing what we think we already know…
In defense of an old way of measuring: “Why Go Imperial in a World Gone Metric?” from @Mikeachim.

As we muse on measurement, we might pause, on Pi Day, for a piece of pi(e)…
… in celebration of Albert Einstein’s birthday; he was born on this date in 1879.
“Everything should be made as simple as possible, but not simpler.”
Taking the measure…
It’s National Metric Week!
As we cheat on conversion, we might recall that it was on this date in 1960 that the meter (AKA “the metre”) was redefined for the fourth time to be 1,650,763.73 wavelengths in vacuum of the orange-red light radiation of the krypton-86 atom (transition between levels 2p10 and 5d5)– a specification 100 times more accurate than the previous (third) legal definition adopted in 1889.
