QotD: Military developments from 1870 onwards
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.

Zeppelins – Majestic and Deadly Airships of WW1 I THE GREAT WAR Special
Published on 8 Feb 2016
Zeppelins pioneered the skyways, could fly long distances and reached heights like none of the British fighter-interceptor aircraft before. Because of that, they were used for scouting and tactical bombing early in the First World War. In this special episode we introduce these majestic floating whales and their usage in WW1.

The death of the duel
ESR has a theory on the rapid decline of the duelling culture that had lasted hundreds of years until the mid-19th century:
I’ve read all the scholarship on the history of dueling I can find in English. There isn’t much, and what there is mostly doesn’t seem to me to be very good. I’ve also read primary sources like dueling codes, and paid a historian’s attention to period literature.
I’m bringing this up now because I want to put a stake in the ground. I have a personal theory about why Europo-American dueling largely (though not entirely) died out between 1850 and 1900 that I think is at least as well justified as the conventional account, and I want to put it on record.
First, the undisputed facts: dueling began a steep decline in the early 1840s and was effectively extinct in English-speaking countries by 1870, with a partial exception for American frontier regions where it lasted two decades longer. Elsewhere in Europe the code duello retained some social force until World War I.
This was actually a rather swift end for a body of custom that had emerged in its modern form around 1500 but had roots in the judicial duels of the Dark Ages a thousand years before. The conventional accounts attribute it to a mix of two causes: (a) a broad change in moral sentiments about violence and civilized behavior, and (b) increasing assertion of a state monopoly on legal violence.
I don’t think these factors were entirely negligible, but I think there was something else going on that was at least as important, if not more so, and has been entirely missed by (other) historians. I first got to it when I noticed that the date of the early-Victorian law forbidding dueling by British military officers – 1844 – almost coincided with (following by perhaps a year or two) the general availability of percussion-cap pistols.
The dominant weapons of the “modern” duel of honor, as it emerged in the Renaissance from judicial and chivalric dueling, had always been swords and pistols. To get why percussion-cap pistols were a big deal, you have to understand that loose-powder pistols were terribly unreliable in damp weather and had a serious charge-containment problem that limited the amount of oomph they could put behind the ball.
This is why early-modern swashbucklers carried both swords and pistols; your danged pistol might very well simply not fire after exposure to damp northern European weather. It’s also why percussion-cap pistols, which seal the powder charge inside a brass casing, were first developed for naval use, the prototype being Sea Service pistols of the Napoleonic era. But there was a serious cost issue with those: each cap had to be made by hand at eye-watering expense.
Then, in the early 1840s, enterprising gunsmiths figured out how to mass-produce percussion caps with machines. And this, I believe, is what actually killed the duel. Here’s how it happened…

Elon Musk, Jeff Bezos and the future of spaceflight
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.

QotD: Progress
Yes, Moist thought, there would be changes. You’d still find horses in town and Iron Girder couldn’t plough, although for a certainty Mr Simnel could make her do so. “Some people will lose out and others will benefit, but hasn’t that been happening since the dawn of time?” he said out loud. “After all, at the beginning there was the man who could make stone tools, and then along came the man who made bronze and so the first man had to either learn to make bronze too, or get into a different line of work completely. And the man who could work bronze would be put out of work by the man who could work iron. And just as that man was congratulating himself for being a smarty-pants, along came the man who made steel. Its like a sort of dance, where no one dares stop because if you did stop you’d be left behind. But isn’t that just the world in a nutshell?”

Your business model and transformative change
At The Arts Mechanical, there’s a paean to the amazing technological achievement represented by this steam engine:
… and a return to reality by looking at how that amazing steam engine was made utterly obsolete by a humble diesel switcher and its direct descendants:
Which brings us to the picture at the head of this post. Anybody ever hear of Lima Locomotive? Here is what they did. That is a C&O RR H8 Allegheny. It is the largest and most powerful steam locomotive ever built. The locomotive was in the shed and there was no way I could get a side shot but the size of it boggles the mind. The firebox is the same size as a small house. The locomotive was designed to move mountains of coal and that’s what it did.

It was also obsolete before it was erected.

The Balance of Industries and Creative Destruction
Published on 18 Mar 2015
Why are price signals and market competition so important to a market economy? When prices accurately signal costs and benefits and markets are competitive, the Invisible Hand ensures that costs are minimized and production is maximized. If these conditions aren’t met, market inefficiencies arise and the Invisible Hand cannot do its work. In this video, we show how two major processes, creative destruction and the elimination principle, work with the Invisible Hand to create a competitive marketplace that works for producers and consumers.

How’s your food innovation level for American Thanksgiving?
Megan McArdle says you can safely avoid novel and baroque food variations for the most stereotypical American meal of all time:
Every year you’re supposed to come up with something amazing and new to do with the most scripted meal in the American culinary canon. Turkey crusted with Marash pepper and stuffed with truffled cornichons. Deconstructed mashed potatoes. Green bean casserole that substitutes kale for the green beans and a smug expression for the cream-of-mushroom soup. Pumpkin-chocolate trifle with a chipotle-molasses drizzle.
I’m sorry, I can’t. I just can’t.
You know what we’re having for Thanksgiving at our house this year? With minor variations, we’re having the same thing we’ve had every year since my birth in 1973. There will be a turkey, roasted whole, because my oven cannot accommodate a spatchcocked 16-pound bird splayed over a sheet pan full of stuffing. It will be brined in a cooler, stuffed full of stuffing despite all the dire culinary injunctions against it, and cooked in the same undoubtedly subpar way we have always done it. My sister will make her homemade cloverleaf rolls, and stuffing with sausage, ginger and apple. There will be cranberry sauce, little creamed onions, mashed potatoes, and butternut squash, with bok choy for those who want greens. For dessert, there will be pie: apple, pumpkin, and perhaps, if we are feeling especially daring, cranberry-raisin.
Novelty is overrated at holidays. If you want to try planked salmon and braised leeks for the first time this year, then bon appetit. But the idea that we must have novelty, that a good cook is constantly seeking out new and better things, is a curse. The best parts of our lives do not require constant innovation; they are the best because they are the familiar things we love just as they are. When I hug my Dad, I don’t think, “Yeah, this is pretty OK, but how much better would it be if he were wearing a fez and speaking Bantu?”

Korea: Admiral Yi – III: The Bright Moonlight of Hansando – Extra History
Published on 10 Oct 2015
While Yi found success at sea, the Korean land army suffered terrible losses. Yi Il, the man who once accused Yi of negligence, lost one battle after another, until finally the regular forces were annihilated at Chungju. The Joseon court that ruled to Korea fled to Pyongyang, on the verge of being pushed out of their own country. But that same day, Admiral Yi tore through a Japanese fleet at Okpo. He moved on to Sacheon, where he baited the Japanese commander into a trap and debuted his turtle ship. The unstoppable turtle ship carried the day, so he used this tactic again and again he destroyed a Japanese fleet while suffering no losses of his own. Finally, Hideyoshi ordered his naval commanders to take Jeolla, Yi’s headquarters. Sadly for him, his general Wakisaka Yasaharu grew too eager and engaged Yi without backup at Gyeonnaeryang Strait, only to find himself lured into an even more sophisticated version of Yi’s bait-and-retreat strategy: a “Crane’s Wing” of ships that collapsed on the overextended target from all sides. In one of the largest naval battles in history, Yi scored a decisive win and again didn’t lose a single ship. He headed to Angolpo to attack Hideyoshi’s two remaining generals and seal his victory, but they refused to be baited. He had to settle for a long range exchange of cannon fire, which worked at the cost of many injuries to his own men. In the end, he destroyed all but a few Japanese ships, and those he only spared to give the Japanese some means to escape and stop raiding in Korea. But he had accomplished his goal: Hideyoshi ordered a halt to all naval operations except guarding Busan, and without this control of the sea, Japan could not re-supply their troops nor hope to resume the assault that would have finally pushed Korea’s leaders out of Korea.

Adam Smith – The Inventor of Market Economy I THE INDUSTRIAL REVOLUTION
Published on 22 Feb 2015
Adam Smith was one of the first men who explored economic connections in England and made clear, in a time when Mercantilism reigned, that the demands of the market should determine the economy and not the state. In his books Smith was a strong advocator of the free market economy. Today we give you the biography of the man behind the classic economic liberalism and how his ideas would change the world forever.

A countertop home-brewing appliance
Pulkit Chandna reviews the “Brewie”:
In the future, at-home beer brewing will be a set-it-and-forget-it cinch, and not the convoluted mess we have always known it to be. That’s the feeling one gets from looking at Brewie, the latest in a series of countertop appliances designed to automate the process of beer crafting.
The Hungarian startup behind it claims Brewie is better and more automated than the competition — including the PicoBrew Zymatic home brewery we reviewed back in June. That lofty claim has helped the company secure hundreds of pre-orders, worth more than $600,000, across two crowdfunding rounds on Indiegogo. It concluded the first leg in February with a funding tally of $223,878, only to return to the site late last month in search of yet more pre-orders. (Indiegogo, as part of its “InDemand program” allows project creators to accept contributions or orders even after their crowdfunding campaign has ended.)
The Brewie is said to distill the whole brewing process down to a series of simple steps requiring negligible human input, such that even the most hopeless of aspiring brewmasters can get started with it in no time at all. You can control the unit either through its 4.3-inch LCD touchscreen or via the companion app over Wi-Fi.

Dilbert‘s Scott Adams on Politics, Philosophy, Hypnosis, and “Failing Towards Success”
Published on 6 Oct 2015
“You can defend an entirely different view of the world using the same data that’s used to defend the standard model. So whenever I can do that, I’m so there,” says Scott Adams. “Because as soon as you realize that the model you’ve been looking at maybe isn’t so firm as you thought… Then you’re free.”
Adams is a man of many talents: Best-selling author behind books such as God’s Debris and How to Fail at Almost Everything and Still Win Big, serial entrepreneur and creator of the time-management system Calendar Tree, and, of course, the man behind Dilbert.
Reason TV‘s Zach Weissmueller sat down with Adams in his home office to discuss Adams’ obsession with Donald Trump (“I see in Trump a level of persuasion technique that is probably invisible to the public” – 1:18), his resistance to political labels (“As soon as I join a group, suddenly all those things that I thought were crazy, I start convincing myself…” – 2:19), his political philosophy (“My preferred political process would be something like business” – 3:08), what Dilbert can teach us about capitalism (“One of those ideas that’s terribly flawed, but we haven’t figured out anything better yet” – 5:22), and the theme that runs through all of his work (“In all cases, I’m interested in the same thing: Is there a different way to look at the familiar?” – 10:05).

“[P]harmaceutical companies … make out like bandits from the existence of the patent system”
The current US patent system is set up to create and maintain — for a limited time — monopolies that can be exploited by pharmaceutical companies:
The Wall Street Journal has a puzzling piece complaining about how the pharmaceutical companies seem to make out like bandits from the existence of the patent system. What puzzles is that the entire point and purpose of the patent system, in an economic sense, is so that inventors of things can make out like bandits. The background problem is that of public goods, something I’ll explain in a moment. That problem leads us to thinking that a pure free market in things which are public goods isn’t going to work as well as something a little different. So, we design something a little different. And the point and purpose of our design is so that people who innovate can make vast mountains of cash out of having done so.
It’s then more than a bit odd to point out that our system enables people who innovate to make vast mountains of cash.
[…]
Which brings us to the subtlety of those pricing decisions. With drugs, pharmaceuticals, close enough the cost of manufacturing a dose is zero. All of the costs go in the original research, the clinical testing (the lion’s share) and getting it through the FDA. Profit is therefore determined, since marginal production costs are zero (they’re not, accurately, but close enough for this comparison), by gross revenue. And we want to maximise the incentive for people to innovate, that’s the very reason we’ve got this patent system in the first place, and thus we would rather like the pharma companies to be maximising revenue.
And thus, from this economic point of view, we should be quite happy with people raising their prices. Demand does fall as they do so, yes, but as long as gross revenue increases, the price rises more than compensating for the fall in unit demand, then we should be happy with the way the system is working. Gross revenue is being maximised, profits are being maximised, incentives to innovate are being maximised. That’s what we want our system to do after all.
Far from being worried about this price gouging we should be welcoming it. Because, obviously, someone making bajillions out of having innovated a drug to cure a disease increases the incentives for many other people to go and invest bajillions of their own to cure other diseases. Far from complaining about it we should be celebrating the system working.
