QotD: Fabric as technology

Filed under: History, Quotations, Technology — Tags: , , , — Nicholas @ 01:00

In February 1939, Vogue ran a major feature on the fashions of the future. Inspired by the soon-to-open New York World’s Fair, the magazine asked nine industrial designers to imagine what the people of ‘a far Tomorrow’ might wear and why. (The editors deemed fashion designers too of-the-moment for such speculations.) A mock‑up of each outfit was manufactured and photographed for a lavish nine-page colour spread.

You might have seen some of the results online: an evening dress with a see-through net top and strategically placed swirls of gold braid, for instance, or a baggy men’s jumpsuit with a utility belt and halo antenna. Bloggers periodically rediscover a British newsreel of models demonstrating the outfits while a campy narrator (‘Oh, swish!’) makes laboured jokes. The silly get‑ups are always good for self-satisfied smirks. What dopes those old-time prognosticators were!

The ridicule is unfair. Anticipating climate-controlled interiors, greater nudity, more athleticism, more travel and simpler wardrobes, the designers actually got a lot of trends right. Besides, the mock‑ups don’t reveal what really made the predicted fashions futuristic. Looking only at the pictures, you can’t detect the most prominent technological theme.

‘The important improvements and innovations in clothes for the World of Tomorrow will be in the fabrics themselves,’ declared Raymond Loewy, one of the Vogue contributors. His fellow visionaries agreed. Every single one talked about textile advances. Many of their designs specified yet-to-be-invented materials that could adjust to temperature, change colour or be crushed into suitcases without wrinkling. Without exception, everyone foretelling the ‘World of Tomorrow’ believed that an exciting future meant innovative new fabrics.

They all understood something we’ve largely forgotten: that textiles are technology, more ancient than bronze and as contemporary as nanowires. We hairless apes co-evolved with our apparel. But, to reverse Arthur C Clarke’s adage, any sufficiently familiar technology is indistinguishable from nature. It seems intuitive, obvious – so woven into the fabric of our lives that we take it for granted.

Blend your own favourite wines right at your kitchen table

Filed under: Technology, Wine — Tags: — Nicholas @ 02:00

In the Economist, a look at a very different kind of wine appliance:

vinfusion-machineTo create a new wine the customer manipulates three sliders on a touch screen attached to the machine. One moves between the extremes of “light” and “full-bodied”. A second runs from “soft”, via “mellow” to “fiery”. The third goes from “sweet” to “dry”. No confusing descriptions like “strawberry notes with a nutty aftertaste” are needed.

The desired glass is then mixed from tanks of each of the four primaries, hidden inside the machine’s plinth. The requisite quantities are pumped into a transparent cone-shaped mixing vessel on top of the plinth. Added air bubbles ensure a good, swirling mix and flashing light-emitting diodes give a suitably theatrical display.

Traditionalists may be appalled by all this, but they should not be. In Mr Wimalaratne’s mind, the function of the Vinfusion system is in principle little different from the blending of grape varieties that goes on in many vineyards, to produce wines more interesting than those based on a single variety. Moreover, if Vinfusion works as intended, it will let people experiment with oenological flavours in a way that is currently impossible and which lets them discover what appeals. A decent sommelier ought then to be able to recommend wines vinified in the conventional way that will taste similar.

In the longer run, recording and collating the requests made to a group of Vinfusion machines might even help restaurants and bars stock bottles that people will like, rather than merely tolerate. And if all this happens, the snobbery and mystique surrounding wine—whether blended in the vineyard or the restaurant—may disappear for good.

The selected “component” wines are chosen for their vintage-to-vintage consistency, so that there’s a lower variability in the wines used to blend your personal selection. This almost certainly wouldn’t work as well with wines from cool climate areas (like Ontario).

A contrarian view of the introduction of the tank

Filed under: Britain, Europe, History, Military, Technology — Tags: , , , , , — Nicholas @ 02:00

At Samizdata, Patrick Crozier gets all contrarian about the tank in a post he titles “Haig’s greatest mistake”:

On 15 September 1916 tanks made their debut at Flers-Courcelette, one of the many engagements which took place during the Battle of the Somme.

The battle marked the beginning of a sorry chapter in British military history because the truth – a truth that to this day few seem prepared to acknowledge – is that the First World War tank was useless.

The list of its failings is lengthy. It was slow, it was unreliable, it had no suspension and it was horrible to operate. The temperature inside was typically over 100°F and as exhaust gases built up so crew effectiveness collapsed. It was also highly vulnerable. Field artillery could take it out easily. Even rifle ammunition could be effective against it. While normal bullets might not be able to penetrate the armour they could knock off small pieces of metal from the inside – known as spall – which then whizzed round the interior wounding all and sundry.

That the tank was the brainchild of Winston Churchill from his days as head of the Admiralty should have alerted senior commanders to the possibility that it was yet another of his crackpot schemes. But they persisted. For his part, Haig being a technophile put a huge amount of faith in the new invention. His diary is littered with references to the tank and he seems to have made great efforts to secure ever more of them. In consequence, huge amounts of effort went into a technological dead end when it would have been far better spent on guns, shells and fuzes.

Not that such efforts were ever likely to satisfy the snake-oil salesmen who made up the ranks of the tank enthusiasts. In the face of tank failure after tank failure they simply claimed that their beloved weapon just wasn’t being used properly.

For years the British had developed the idea of the “landship” or tank and now it was finally ready for the first deployment during the Battle of Flers-Courcelette. And even though technical problems plagued the new invention, the British leadership was confident that this new weapon would break the stalemate at the Western Front for good. In the meantime Germany was focusing all offensive efforts on the Romanian front to mercilessly crush the new enemy.

The idea for an armoured vehicle that could withstand fire and travel across battlefields was already developed in 1914 after the Race to the Sea. The British “Landship Committee” developed the tank weapon in secrecy. The French were also trying out different designs at the same time. Learn all about the development and the invention of the tank in our special episode.

QotD: “Thought collectives” in science

Filed under: Quotations, Science — Tags: , — Nicholas @ 01:00

In a 2015 paper titled Does Science Advance One Funeral at a Time?, a team of scholars at the National Bureau of Economic Research sought an empirical basis for a remark made by the physicist Max Planck: “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”

The researchers identified more than 12,000 “elite” scientists from different fields. The criteria for elite status included funding, number of publications, and whether they were members of the National Academies of Science or the Institute of Medicine. Searching obituaries, the team found 452 who had died before retirement. They then looked to see what happened to the fields from which these celebrated scientists had unexpectedly departed, by analysing publishing patterns.

What they found confirmed the truth of Planck’s maxim. Junior researchers who had worked closely with the elite scientists, authoring papers with them, published less. At the same time, there was a marked increase in papers by newcomers to the field, who were less likely to cite the work of the deceased eminence. The articles by these newcomers were substantive and influential, attracting a high number of citations. They moved the whole field along.

A scientist is part of what the Polish philosopher of science Ludwik Fleck called a “thought collective”: a group of people exchanging ideas in a mutually comprehensible idiom. The group, suggested Fleck, inevitably develops a mind of its own, as the individuals in it converge on a way of communicating, thinking and feeling.

This makes scientific inquiry prone to the eternal rules of human social life: deference to the charismatic, herding towards majority opinion, punishment for deviance, and intense discomfort with admitting to error. Of course, such tendencies are precisely what the scientific method was invented to correct for, and over the long run, it does a good job of it. In the long run, however, we’re all dead, quite possibly sooner than we would be if we hadn’t been following a diet based on poor advice.

The economic consequences of sustained cheap oil

Filed under: Business, Economics — Tags: , , — Nicholas @ 02:00

Tim Harford explains why cheaper oil is generally speaking good for the economy:

After years in which $100 oil was the norm, the price of Brent crude is now around a third of that. Assume for a moment that Russia and Saudi Arabia fail in their efforts to get the price back up. Will $30 oil change the world? The answer is yes, of course. Everything is connected to everything else in economics, and that is particularly true when it comes to oil. For all the talk of the weightless economy, we’re not quite so post-industrial as to be able to ignore the cost of energy. Because oil is versatile and easy to transport, it remains the lubricant for the world’s energy system.

The rule of thumb has always been that while low oil prices are bad for the planet, they’re good for the economy. Last year a report from PwC estimated that a permanent fall in the price of oil by $50 would boost the size of the UK economy by about 1 per cent over five years, since the benefits — to most sectors but particularly to heavy industry, agriculture and air travel — would outweigh the costs to the oil production industry itself.

That represents the conventional wisdom, as well as historical experience. Oil was cheap throughout America’s halcyon years of the 1950s and 1960s; the oil shocks of the 1970s came alongside serious economic pain. The boom of the 1990s was usually credited to the world wide web but oil prices were very low and they soared to record levels in the run-up to the great recession. We can debate how important the oil price fluctuations were but the link between good times and cheap oil is not a coincidence.

Here’s a piece of back-of-the-envelope economics. The world consumes nearly 100 million barrels a day of oil, which is $10bn a day — or $3.5tn a year — at the $100 price to which we’ve become accustomed. A sustained collapse in the oil price would slice more than $2tn off that bill — set against a world economic output of around $80tn, that’s far from trivial. It is a huge transfer from the wallets of oil producers to those of oil consumers.

QotD: Military developments from 1870 onwards

Filed under: Europe, History, Military, Quotations, Technology — Tags: , , — Nicholas @ 01:00

The period of Colonial expansion coincided with three major developments in weapon-power: the general adoption of the small-bore magazine rifle, firing smokeless powder; the perfection of the machine gun; and the introduction of quick-firing artillery.

By 1871, the single-shot breech-loading rifle had reached so high a standard of efficiency that the next step was to convert it into a repeating, or magazine, rifle. Although the idea was an old one, it was not fully practicable until the adoption of the all-metal cartridge case, which reduced jamming in the breech. The first European power to introduce the magazine rifle was Germany who, in 1884, converted her 1871 pattern Mauser rifle to the magazine system; the magazine was of the tube type inserted in the fore-end under the barrel, it held eight cartridges. In 1885, France adopted a somewhat similar rifle, the Lebel, which fired smokeless powder — an enormous advantage. Next, in 1886, the Austrians introduced the Mannlicher with a box magazine in front of the trigger guard and below the entrance to the breech. And two years later the British adopted the .303 calibre Lee-Metford with a box magazine of eight cartridges, later increased to ten. By 1900 all armies had magazine rifles approximately of equal efficiency, and of calibres varying from .315 to .256; all were bolt operated, fired smokeless powder, and were sighted to 2,000 yards or metres.

Simultaneously with the development of the magazine rifle proceeded the development of the machine gun — another very old idea. Many types were experimented with and some adopted, such as the improved Gatling, Nordenfeldt (1873), Hotchkiss (1875), Gardner (1876), Browning (1889) and Colt (1895). The crucial year in their development was 1884, when Hiram S. Maxim patented a one barrel gun which loaded and fired itself by the force of its recoil. The original model weighed 40lb., was water cooled and belt fed, and 2,000 rounds could be fired from it in three minutes. It was adopted by the British army in 1889, and was destined to revolutionize infantry tactics.

The introduction of quick-firing artillery arose out of proposals made in 1891 by General Wille in Germany and Colonel Langlois in France. They held that increased rate of fire was impossible unless recoil on firing was absorbed. This led to much experimental work on shock absorption, and to the eventual introduction of a non-recoiling carriage, which permitted of a bullet-proof shield being attached to it to protect the gun crew. Until this improvement in artillery was introduced, the magazine rifle had been the dominant weapon, now it was challenged by the quick-firing gun, which not only outranged it and could be fired with almost equal rapidity, but could be rendered invisible by indirect laying.

Elon Musk, Jeff Bezos and the future of spaceflight

Filed under: Space, Technology, USA — Tags: , , , , , — Nicholas @ 02:00

Colby Cosh on the real significance of the private space companies’ successes:

The science fiction authors who originally imagined spaceflight thought it would be classically capitalistic in nature — a Wild West of chancers, gold-diggers, outlaws, and even slave-traders transposed to the skies. It ended up, in its first incarnation, being a government program. This had the merit of showing that some impossible technical problems could be solved if you threw near-infinite resources and human lives at them. But the money and will ran out before NASA got around to figuring out how to make orbital spaceflight truly routine. Reusable rockets are the important first step that NASA didn’t have time to try in the Golden Age, under the pressure of a “space race” between governments.

Musk and Bezos are trying, I think very consciously, to revive the public interest and inspiration that this race narrative once brought. When SpaceX stuck its landing this week, having previously had a couple of flops, Bezos tweeted “Welcome to the club!” Musk will not mind the cheap shot too much. Bezos is doing him a favour by making a game of it.

It is hard for us to feel passion about accounting, even when “accounting” translates to cheaper satellite technology that means subtle advances in science and cost cuts in earthbound communications tech. Anything you can turn into a mere clash of personalities will get the attention of journalists and readers more readily. Musk and Bezos are exploiting their position as two of the great stage characters of our day.

The benefit they’re really going for is to bring a slightly larger margin of the human neighbourhood within reach for spaceships assembled on orbital platforms — the only practical kind of spaceship, as it seems to have turned out. Routine orbital access means affordable space tourism; it means possible Mars missions predicated on traditional exploration/adventure motives; it means deeper scientific scrutiny and even commercial study of the Moon, the asteroids, perhaps the inner planets. It means space stations that aren’t just for handpicked careerist supermen.

It means — well, we don’t know, from this side of the future, what it means. Some grade-three kid out there may already have a “killer app” for reusable rockets that nobody has considered yet. (If the cost comes down far enough, are we certain rockets won’t re-emerge as a possibility for long-haul terrestrial travel? That’s another assumption of early SF we have discarded, perhaps carelessly!) But it is probably a good guess that the balletic SpaceX triumph will turn out, after the fact, to have been one of the biggest stories of 2015.
