Fading Away

By Randy Bancroft

10 years ago on Pi Day, the Metric Maven website posted its first essay, The Invisible Infrastructure. My advisor and long-time friend Sven predicted I might have a 6 month run before running out of subjects to discuss. I thought he might be right, but decided to do my best to research the metric system. Now it has been 10 years and over 250 essays. I wrote a history of the metric system in the United States, Death by 1000 Cuts. I also wrote a book exploring the use of the metric system that includes all the current metric prefixes, titled The Dimensions of The Cosmos. I approached literary agents for years without any ability to engage their interest. I self-published Dimensions of the Cosmos, which proved to be a disaster. Despite this, I wrote a second edition of The Dimensions of The Cosmos. I finally decided that it would be best to offer both books online for anyone who is interested. I’m planning on continuing to offer chapters from The Dimensions of the Cosmos on this website until the entire monograph has been published, and then post the book as a single complete file.

What has become painfully clear over the last ten years is that the political system in the United States has no ability to reform itself, and I will not see another discussion of metric conversion in my lifetime. It has become painfully obvious, that at best, I’ve been writing for posterity. At this point, I feel I’m an American stranded on a small non-metric island, with one bottle into which I can put a note, and throw it into the sea, hoping that posterity takes an interest.

In the US, there is an overwhelming belief in the efficacy of technical Darwinism. That a better mouse trap will lead the world to your door. This statement is attributed to Ralph Waldo Emerson, but he never used the word mousetrap. The need for a government metric mandate to implement the metric system in the US proves to the followers of this mythology, that the metric system is clearly inferior to the farrago of units produced by “market Darwinism.”

Years before the pandemic, I read Flu: The Story of the Great Influenza Pandemic of 1918 and the Search for the Virus that Caused it, by Gina Kolata and The Great Influenza by John M. Barry. I was quite concerned about a possible new pandemic, but furtively hoped it would never happen in my lifetime. In 1918, no one knew what a virus was, and only its size could be determined using filters. These became known as filterable viruses. There was nothing medical science could offer, other than masks, and there was uncertainty as to their efficacy in those days.

When the Covid19 pandemic arrived, viruses were scientifically understood, but developing a vaccine would be difficult, and take time. To my astonishment, researchers were able to fast-track a new method of vaccination, with 10 years of groundwork, using messenger RNA. I was gobsmacked, it was a scientific miracle. The researchers had set a goal of 50% effectiveness, and instead, it was north of 90%. The vaccine did not need to be grown in eggs, it could be quickly manufactured using PCR. Talk about a better mouse-trap!

Despite this amazing development, a large number of people simply refused to be vaccinated. Considering the death rate of SARS Cov-2 is as bad or worse than that of the 1918 flu, one would think the rational reaction would be for everyone to get vaccinated as soon as possible. Even after numerous anti-vax proponents perished, their followers continued to endanger themselves and the community by remaining susceptible. For them, seeking the vaccine remained anathema. In 2020, Alabama had more deaths than births. This has never happened before. Finally, there was government action to mandate vaccinations. A visceral and violent reaction followed. I recall the first assumption made in my university class on economics was that people are rational. I’ve seen little evidence of this. My essay Zombie Metric Reform illustrates the fallacy of the rational consumer. The most fictional part of the pre-pandemic movie Contagion, was that after a vaccine was found, everyone would get it.

It struck me, that the reaction against vaccine mandates, is the same general type of excuse trotted out over and over in the US. Any call for a metric system mandate is met with red-faced invective. The Metric Maven post that generated the most comments ever, 94, was The Metric Philosophers, which called for a metric mandate, and questioned those who have waited 150 years for technical Darwinism to bring the metric system to us. It appears this view upset some readers so much, they never returned. I don’t believe the US political system has the ability to govern in a way that promotes the general welfare, only specific welfare, and so I don’t expect the metric system to ever be adopted in the US.

Offering my books and essays online for free, was offering free vaccine to those who would not take it no matter what. One day on LinkedIn I replied to a person arguing against the metric system for use with printed circuit boards. An engineer I had known for ten years, replied to my rebuttal, by insinuating I was a commie, or maybe just a pinko?–for the temerity to promote the metric system in the US. Wow. I offered some metric essays for him to ponder, but as Thomas Paine said:

To argue with a man who has renounced the use and authority of reason, and whose philosophy consists in holding humanity in contempt, is like administering medicine to the dead ….

When I think of the use of medieval measurement units in the US, I cannot help but think of this quotation by Ralph Waldo Emerson:

A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines.

The metric note in a bottle I offer to throw into the cyber-sea, is a collection of what I believe are the most important essays I’ve written for the general public, and posted over the years. I have given this collection of essays the title: Our Crumbling Invisible Infrastructure. It has the subtitle Essential Essays by the Metric Maven. You may download it below, or in the metric resources section of this website.

After 10 years, I plan on stepping back from posting essays on the metric system in the future. I may still post every month, if a subject appears, or I may not post again if there is nothing of interest to discuss in the future.

I want to thank all those that made this effort possible: Pat Naughtin, Peter Goodyear, Mike Joy, Amy Young, Sven, and to others I’ve probably overlooked, I apologize.

Project Hail Mary

I worked in aerospace for about 8 years, and in commercial engineering for about 15 years. The last company I worked for was packed-up and divided between China and India. I found myself accidentally becoming an engineering consultant. I expected to do this for perhaps 2 or 3 years at most, and then take a full-time position. It has been 14 years. When I found myself setting up my lab, it was a bit like how Thomas Paine described the potential of the young United States: “We have it in our power to begin the world over again.”

I decided there must be a person or persons somewhere that had studied and investigated the best way to use the metric system. The person I found by internet search was Pat Naughtin. He had wisdom and experience, but I had provincial American certainty in my unexamined views. Fortunately, I had Sven, and also the ability to change my view when the information I have changes. I very soon understood the utility of millimeters, and the Olde English distraction of centimeters. Cultural inertia in the US provides a ready barrier to adopting intellectual change—even when it is clearly superior after dispassionate examination.

It has been decades since I last worked in aerospace. I know a couple of engineers who worked in commercial, and moved to aerospace after our commercial company off-shored. I had lunch with them, and when I mentioned a dimension in millimeters, one of the pair jokingly said “what’s a millimeter?” Thirty years after I had worked in aerospace, and had metric drawings rejected, aerospace still uses inches, foot-pounds, and other non-SI measures, when the non-US world uses metric.

As I’ve pointed out in the past, the use of Ye Olde English (Imperial is New English) measures has colored our view of how to most efficiently implement a measurement system. The compulsion to translate the new system into the same familiar measures seems irresistible. Inches are a familiar size of pre-metric measure, so we’ll have a centimeter. This does two things psychologically, it first validates the current measurement prejudice, and second it diminishes the importance of adopting the metric system at all. A number of European countries adopted the metric system in the 19th century, and adopted an “Imperialized” view of metric usage, embracing the centimeter, deciliters, and such. When I question the use of centimeters there is often a visceral reaction: “lots of people use centimeters, they’re perfectly fine.” This is very strange, as it is the same non-argument Americans use about inches, feet, and so on. It was only the later adoption of metric in places like Australia, New Zealand, South Africa and others that allowed for more introspection, and a more rational adoption of efficient metric practices.

The instinctive reaction is to look for the commonality in measures, and equate the Anglo-Saxon compromise inch with centimeters. This was certainly the case in aerospace. It was seldom that metric was used in a discussion, but when it was you can be sure it was with Olde English interpretation in mind. Thirty years have passed, and for the last 14 I’ve tried to implement as much simplified metric as possible. Has any measurement change occurred in aerospace since my absence?

This year, 2021, Andy Weir published his new novel Project Hail Mary. I almost never read fiction anymore, but the gushing over this novel caused me to purchase a copy. Before I say anymore, this novel is the best piece of science fiction I’ve seen in decades. This is hard science fiction. Science is constantly used to move the plot along. There are no large dog-fights between space ships. No buxom space women. If you like SCIENCE in your science fiction, this is the book for you. I highly recommend it. It is like a combination of Isaac Asimov’s The Gods Themselves, The Currents of Space, Micheal Creighton’s The Andromeda Strain, and well, many other classic works of science fiction. This book is truly unique in today’s science fiction zeitgeist. I’m going to do my best not to introduce any spoilers, so forgive some of the vague discussion that follows.

It appears Andy Weir worked in government labs, and commercial companies for much of his career as a computer programmer. The use of metric throughout Project Hail Mary is consistent with the same pidgin metric I recall from my days in aerospace, and much of my commercial experience. Amazingly, early in the novel, metric usage is important to the plot, which is refreshing, but it also would could have been more nuanced if the author had a more expanded view of metric usage. His usage is consistent with the same metric usage I experienced in aerospace 30 years ago—nothing appears to have changed. I find no fault with Andy Weir, he is offering me a touchstone of the metric ossification that exists in 2021.
Most readers will never notice.

Andy Weir uses the term imperial for pre-metric measures and does not make distinction between Ye Olde English, and New English measures. I don’t fault him for this, as it is part of the word-of-mouth tradition in the US, rather than education based on investigatory work. I suffered from it myself. Microns are constantly in use, but I don’t recall a single micrometer within the text. There is a constant back-and-forth of pre-metric and metric units. The book is a centimeter smorgasbord with millimeters seldom encountered. The irresistible cultural force to phase-lock onto a unit that preserves pre-metric usages is a powerful one. The separation of what could be all millimeters into centimeters and millimeters is seen as normal:

“The solar disc is 27 centimeters on-screen and the sunspots are 3 millimeters. And they moved half their width (1.5 millimeters) in ten minutes…..”

Andy Weir has an understanding of how non-metric use is detrimental for American engineers and scientists:

“The tunnel is about 20 feet long. Or 7 meters. Man, being an American scientist sucks sometimes. You think in random, unpredictable units based on what situation you’re in.”

There is a point in Project Hail Mary where the definition of units becomes of importance, and centimeters are chosen. There is a place where a measurement error is of great importance to the plot, but as I said—no spoilers. Finally there is this:

“Yes, inches. When I’m stressed out, I revert to imperial units. It’s hard to be an American, okay?”

It is a sort of echo of Naughtin’s 1st Law: Dual-Scale Instruments are Evil. One reverts back to what one has used since grade-school. The educational system decides what “comfortable” measurement units are when you are young, and it makes it more difficult to “get a feel” for new units in an ocean of “imperial.”

Project Hail Mary gave me a touchstone into how metric is used in industry. Andy Weir has a very, very, promising future as a science fiction writer. I’m very hopeful that with all the use of measurement found in his novel, that he takes some time to look into modern metric usage, and perhaps integrate it into future work.
