Tools, adaptation, and seriousness of work

Impressions

The stuffed wingback chair in my office puts me at eye level with my woodworking books, which was not deliberate but maybe not entirely accidental either. Last week I noticed a book I’d forgotten I’d bought: The Village Carpenter, written by Walter Rose in 1937, a memoir of life as a carpenter in an English village in the late nineteenth century. There’s a great deal here that interested me, both as a woodworker and as a rural historian, and I may have more to say about it later, but what struck me most was the relationship Rose describes between the workers, their methods of work, and their tools—the ecosystem of the craft, you might say.

Several years ago, as I tried to get back into serious woodworking, I realized that if I was going to continue I was going to need to sharpen my saws, which were a decade or more old and growing too dull to use effectively. But I couldn’t find anyone who could sharpen a handsaw for me, and I knew I wasn’t going to figure out how to do it from books and videos alone. So I took a class on sharpening hand saws, and I dutifully took along my old, dulled crosscut saw for practice.

It turned out that my old, dulled crosscut saw could not be sharpened. “Modern” saws of the sort sold by big box home centers are made of steel tempered too hard to be sharpened with a steel file. They’re designed to stay usably sharp for a long time… and then to be thrown away and replaced.

Most of us, in other words, aren’t even used to the idea that tools have to be maintained.

Smart tools, dumb craft

I have a new microwave, or rather I have an old microwave that is new to me. I don’t like it. It is bigger and more powerful than my old microwave. I didn’t need a bigger and more powerful microwave, but I don’t object to the size or the power. Actually I wasn’t entirely convinced I needed a microwave at all; I use it for very few things. Mainly I defrost meat, because I am good at putting together dinner on the fly but bad about planning ahead; and soften butter, because my daughter likes to bake, but, well, ditto.

I don’t like this microwave because it has too many single-use buttons and multi-step programmed procedures and not enough basic flexible options. I don’t mean that it is too complicated as such, because some tools have a lot of functions and thus need complicated means of interaction. The problem is that its interface is far more complicated than it needs to be, and sufficiently complicated that its design actually interferes with intelligent use.

Here’s an example. If I wanted, with my old microwave, to soften a stick of butter to cool room temperature, I could simply “defrost” it for about 20 seconds. I had only to lower the power and set a time. On the new one, there isn’t a simple way to lower the power; there are only options for various specific foods and purposes. So I have to press “soften/melt,” then watch a scrolling digital readout asking me to press a number for whether I’m softening or melting, and then another number for what sort of food item I have, and then a third for how many sticks of butter. The old process required me to press four easily readable buttons (defrost, 2, 0, start) and worked perfectly, because I’d experimented a bit to see how long it took to soften a stick of butter. The new process takes a good ten seconds to get started and halfway melts the butter, so that I have to stand and watch it through the (typically streaked and greasy) glass. And if I want to soften half a stick, I’m out of luck. Same for defrosting less than a pound of meat. It simply isn’t an option. And while there may be some way to make the machine do what I want, I’ll have to find a manual somewhere online to figure out how, because the “custom” settings aren’t.

I was thinking, yesterday, about how I would solve this problem. One way would be to plan ahead and/or just use the gas stove, but that’s not really in keeping with the spirit of the age, so take it as a design problem. Here are some observations:

Technological change and the hard work of parenting

Impressions

Alison Gopnik reports in the Wall Street Journal: “Two large-scale surveys done in 2007 and 2013 in the Netherlands and Bermuda, involving thousands of adolescents, found that teenagers who engaged in more online communication also reported more and better friendships.”

That’s a heartening correlation to anyone who doesn’t want to have to worry about the consequences their kids’ technology use, but it isn’t causality. It should not be surprising that people who have more and closer friendships would communicate with those friends by whatever means their society and economy provides, and that “more online communication” would thus correlate with “more and better friendships.” I do wonder what, exactly, “more and better friendships means”; in particular I wonder if the researchers’ construction of that idea ultimately collapses into a definition of extraversion, but I’m not interested enough to dig up the original article. I’m more interested in Gopnik’s use of the study, which is to dismiss the worries of parents (or of anyone else) as mere nostalgia.

A cultural sleep

Impressions

Jessica Gamble describes new techniques and technologies whose inventors would radically reduce or eliminate the human need for sleep:

Transcranial direct-current stimulation (tDCS) is a promising technology in the field of sleep efficiency and cognitive enhancement. Alternating current administered to the dorsolateral prefrontal cortex through the thinnest part of the skull has beneficial effects almost as mysterious as electroconvulsive therapy (ECT), its amnesia-inducing ancestor. Also known as ‘shock therapy’, ECT earned a bad name through overuse, epitomised in Ken Kesey’s novel One Flew Over the Cuckoo’s Nest (1962) and its 1975 film adaptation, but it is surprisingly effective in alleviating severe depression. We don’t really understand why this works, and even in today’s milder and more targeted ECT, side effects make it a last resort for cases that don’t respond to drug treatment. In contrast to ECT, tDCS uses a very mild charge, not enough directly to cause neurons to fire, but just enough to slightly change their polarisation, lowering the threshold at which they do so.

Using a slightly different technique — transcranial magnetic stimulation (TMS), which directly causes neurons to fire — neuroscientists at Duke University have been able to induce slow-wave oscillations, the once-per-second ripples of brain activity that we see in deep sleep. Targeting a central region at the top of the scalp, slow-frequency pulses reach the neural area where slow-wave sleep is generated, after which it propagates to the rest of the brain. Whereas the Somneo mask is designed to send its wearers into a light sleep faster, TMS devices might be able to launch us straight into deep sleep at the flip of a switch. Full control of our sleep cycles could maximise time spent in slow-wave sleep and REM, ensuring full physical and mental benefits while cutting sleep time in half. Your four hours of sleep could feel like someone else’s eight. Imagine being able to read an extra book every week — the time adds up quickly.

The benefits are so obvious that Gamble doesn’t actually argue in favor of all this technological wonder and post-evolutionary glory; instead, she insists that no present-day person can logically argue against it:

The question is whether the strangeness of the idea will keep us from accepting it. If society rejects sleep curtailment, it won’t be a biological issue; rather, the resistance will be cultural…. Such attempts are likely to meet with powerful resistance from a culture that assumes that ‘natural’ is ‘optimal’. Perceptions of what is within normal range dictate what sort of human performance enhancement is medically acceptable, above which ethics review boards get cagey. Never mind that these bell curves have shifted radically throughout history. Never mind that if we are to speak of maintaining natural sleep patterns, that ship sailed as soon as artificial light turned every indoor environment into a perpetual mid-afternoon in May.

Setting aside, for the moment, the matter of sleep, there’s an interesting assumption lurking beneath that paragraph, and I think it’s worth ferreting out, because the opponents Gamble imagines share it.

Pink slime: Or, the whole scrapple

ImpressionsUncategorized

My main thought on all this horror over “pink slime” is that it doesn’t sound any worse than any food-like product I’d expect to come out of a factory. I mean, what do you expect? The goal of the U.S. food industry is to produce substances that are chemically compatible with the maintenance of human life and that are aesthetically and culturally palatable to American consumers, all at the greatest possible margin of profit. Pink slime, duly flavored with extracts, shaped into a patty, topped with half the contents of the refrigerator and eaten by a model with juice dribbling down her chin, pretty much nails it.

But I get tired of reading only people I agree with, so I went looking for contrary arguments.

These days it’s all green this and renewable that, solar houses and electric cars and trains that run on cow farts. Well, look, my woodshop runs on solar energy, too. My daughter drew this diagram to show you all how it works:

I admit I do run a fluorescent light and a radio. But otherwise it’s just the sun, grass, cows, and me. Ain’t no energy greener than hand power, friends.

Ignorance is fear: or, “it’s gross” is not an argument

Impressions

A former “food industry insider” named Bruce Bradley has started a blog to tell the world about all the terrible things the food industry does. In his most recent post, he lists some of the disgusting things that industry passes off as natural products. “Unfortunately,” he writes, “big food companies have cast a spell over most regulators that allows them to manipulate us with advertising, make deceptive claims, and mislead us with ingredient labels.”

I appreciate the effort to speak truth to powerless, but here’s the problem: Three of the five things he lists have been commonly used for centuries or, in some cases, millennia. Not only are they, in fact, natural; they’re traditional and originally handmade.

A couple of weeks ago I spent my first day volunteering as a costumed museum interpreter, which is not something I ever saw myself doing. I’d worked with the site director and staff before, and figured that, as an out-of-work historian, I’d see if I could help them out in any way — doing a little research or leading a few tours, I thought, but when they found out that I build furniture with hand tools, the next thing I knew I was being fitted for 1870s clothes. And so there I was on a ninety-degree North Carolina June Saturday outside a nineteenth-century farmhouse demonstrating “traditional” woodworking.
