QotD: What the GDP is failing to show (even though it’s there)
There simply isn’t a technology that has come anywhere close to arriving in the hands of actual users as fast as the smartphone and mobile internet. The next closest competitor is the mobile phone itself. All others running distant third and behind.
Our problem is that we know technological revolutions produce growth. Yet economic growth is limp at best, meagre perhaps a better description. So, there’s something wrong here. Either our basic understandings about how growth occurs are wrong and we [are] loathe to agree to that. Not because too much is bound up in that understanding but because too much of it makes sense. The other explanation is that we’re counting wrong.
[…]
We know that we’ve not quite got new products and their falling prices in our estimates of inflation quite correctly. They tend to enter the inflation indices after their first major price falls, meaning that inflation is always overstated. Given that the number we really look at is real growth – nominal growth minus inflation – this means we are consistently underestimating real growth.
[…]
The more we dig into this the more convinced I am that our only real economic problem at present is counting. Everything makes sense if we are counting output and inflation incorrectly, under-estimating the first, over- the second. If we are doing that – and we know that we are, only not quite to what extent – then all other economic numbers make sense. We’re in the midst of a large technological change, we’ve full employment by any reasonable measure, wages and productivity should be rising strongly. If we’re mismeasuring as above then those two are rising strongly, we’re just not capturing it. Oh, and if that’s also true then inequality is lower than currently estimated too.
The thing is, the more we study the details of these questions the more it becomes clear that we are mismeasuring, and mismeasuring enough that all of the claimed problems, the low growth, low productivity rises, low wage growth, simply aren’t there in the first place. And if they ain’t then nothing needs to be done about them, does it? Except, perhaps, count properly.

Winchester Lever Action Development: Model 1866
Forgotten Weapons
Published 7 Jun 2017While the Henry Repeating Rifle had been an serious leap forward in firearms capability, it was not without problems. The biggest single weakness of the Henry was its magazine. The tube magazine was open to dirt and debris, the follower could easily come to rest on the shooter’s hand or anything used as a rest and stop the weapon from feeding, and the while system was rather prone to being damaged.
These problems would all be addressed with the addition of Nelson King’s new loading gate idea, which allowed Winchester to omit the exposed follower entirely, solving a bunch of complaints all at once. The new system was more durable, more reliable, and allowed the rifle to be loaded without the awkward manipulation required by the Henry. The King improvement also allowed the addition of a wooden handguard, which was a welcome addition — it does not take very many black powder rounds for a barrel to become uncomfortably hot to the touch.
At the same time that these improvements were being made, company politics were taking shape to end Benjamin T. Henry’s involvement with the company. Henry attempted to take over ownership of the company because he felt he was not profiting as much as he should, but he had assigned his patent rights to Oliver Winchester in exchange for his contract to manufacture the guns. As a result, Winchester was able to create a new company (the Winchester Repeating Arms Company) with full rights to the design patents and sideline Henry.
The 1866 rifle, which was formally called simply the Winchester Repeating Rifle would continue to use the .44 Henry Rimfire cartridge, but would be made in a wider variety of configurations than the Henry had been, including carbine, rifle, and musket barrel lengths. It would prove to be a very popular rifle, and opened the path to further improvement, as it put the Winchester company on excellent financial footing.

Winchester Lever Action Development: 1860 Henry
Forgotten Weapons
Published 5 Jun 2017The Henry Repeating Rifle was a truly revolutionary development in firearms technology. It was not the first repeating rifle, but it was the best of a emerging class of new arms, reliable in function and very fast to shoot (much faster than the contemporary Spencers). The Henry used a simple toggle lock locking system, with a single throw of its lever performing all the elements necessary to reload and recock the action.
The Henry’s quick action was coupled with a 15-round magazine, more than double what the Spencer offered. It fired the .44 Henry rimfire cartridge, which threw a 216 grain bullet at about 1125 feet per second (this would change to 200 grains at 1200 fps within a few years). This was substantially less powerful than a heavy muzzleloader charge, but the volume of fire more than made up for it. Within 200 yards, the Henry could produce a devastating volume of fire.
The Henry was only produced for about 5 years (1862 – 1866), with about 12,000 manufactured in total. The Henry was made almost exclusively in a standard rifle pattern, with a 24 inch barrel. Some were later cut down into carbines, though. While the US military rejected the Henry for a variety of reasons, nearly all of the guns produced before the end of the war did actually see military service, with state units or individuals who supplied their own arms. In the few engagements where Henry rifles were present in substantial numbers, they proved to be a significant force multiplier.

From innovation to absolutism — English inventors and the Divine Right of Kings
In the latest Age of Invention newsletter, Anton Howes looks at how innovations during the late Tudor and Stuart eras sometimes bolstered the monarchy in its financial battles with Parliament (which, in turn, eventually led to actual battles during the English Civil War):

King Charles I and Prince Rupert before the Battle of Naseby 14th June 1645 during the English Civil War.

The various schemes that innovators proposed — from finding a northeast passage to China, to starting a brass industry, to colonising Virginia, or boosting the fish industry by importing Dutch salt-making methods — all promised to benefit the public. They were to support the “common weal”, or commonwealth. And to a certain extent, many projects did. The historian Joan Thirsk did much pioneering work in the 1970s to trace the impact of various technological or commercial projects, revealing that even something as mundane as growing woad, for its blue dye, could have a dramatic impact on local economies. With woad, the income of an ordinary farm labouring household might be almost doubled, for four months in the year, by employing women and children. In the late 1580s, the 5,000 or so acres converted to woad-growing in the south of England likely employed about 20,000 people. That may seem small today, but at a time when the population of a typical market town was a paltry 800 people, even a few hundred acres of woad being cultivated here or there might draw in workers from across the whole region. In the mid-sixteenth century, even the entire population of London had only been about 50-70,000. As Thirsk discovered, innovative projectors also sometimes fulfilled their other public-spirited promises, for example by creating domestic substitutes for costly imported goods, or securing the supplies of strategic resources.
But the ideal of benefiting the commonwealth could also, all too frequently, be elided with serving the interests of the Crown. Projectors might promise the monarch a direct share of an invention’s profits, or that a stimulated industry would result in higher income from tariffs or excise taxes. Increasingly, they proposed schemes that were almost entirely focused on maximising state revenue, with little evidence of new technology. They identified “abuses” in certain industries — at this remove, it’s difficult to tell if these justifications were real — and asked for monopolies over them in order to “regulate” them, then making money by selling licences. Last week I mentioned patents over alehouses, and on playing cards. They also offered to increase the income from the Crown’s property, for example by finding so-called “concealed lands” — lands that had been seized during the Reformation, but which through local resistance or corruption had ostensibly not been paying their proper rents. The projectors would take their share of the money they identified as “missing”. And they proposed enforcing laws, especially if the punishments involved levying fines or confiscating property. The projectors offered to find the lawbreakers and prosecute them, after which they’d take their share of the financial punishments.
Projectors thus came to present themselves as state revenue-raisers and enforcers, circumventing all of the traditional constraints on the monarch’s money and power. They provided an alternative to Parliaments, as well as to city corporations and guilds, in raising money and propagating their rule. Taking it a step further, projectors offered the tantalising possibility that kings like James I and Charles I might rule through proclamation and patents alone, without having to answer to anybody. They thus experimented with absolutism for much of 1610-40, only occasionally being forced to call Parliament for as briefly as possible when the pressing financial demands of war intervened.
In the process, with the growing multitude of projects — a few bringing technological advancement, but many merely lining the pockets of courtier and king — the designation “projector” became mud. It was as if, today, the Queen were to use her prerogative to grant a few of her courtiers monopolies on collecting all traffic fines, or litter penalties, to be rewarded solely on commission. Or if she were to award an unscrupulous private company the right to award all alcohol-selling licences (perhaps on the basis that underage drinking was becoming common). The country would soon be awash with hidden speed cameras and incognito litter wardens, and the price of alcohol would go through the roof. The people responsible would not be popular. A recent book by economic historian Koji Yamamoto meticulously charts the changing public perceptions of projects, describing the ways in which innovators then struggled, for decades, to regain the public’s trust.

Britain’s technological edge in the Battle of Britain
Over at The Register, Gareth Corfield lists some of the advanced technological kit the Royal Air Force had access to during the Battle of Britain in 1940:

Technology played its part, mostly behind the scenes – yes, we mean the backroom boffins – in equipping Britain to hold firm and defeat the Germans. As today’s commemorations focus on the pilots and ground crew who saw off the Luftwaffe, spare a thought for the technologists whose efforts also saved the western world.
Radar and radio
Chief among the technological innovations that gave the RAF the edge was radar. In the 1930s Britain was one of the world leaders in radar (thanks in part to a bizarre and unsuccessful experiment to kill sheep with a death ray) leading to the building of radar stations all around the British coast.
Sir Robert Watson-Watt, today regarded as the father of radar, was instrumental in devising a method of bouncing radio waves off a flying aeroplane to figure out its location. He turned that 1935 concept into the fully operational Chain Home and Chain Home Low air defence networks inside four years.
Without radar, the RAF was totally reliant on humans with binoculars spotting incoming formations of German bombers; radar gave the air force an early warning capability as hostile aircraft formed up over France before crossing the Channel.
Before radar came radio direction-finding. The RAF’s Home Defence Units were first established in the 1920s and mastered the art of pinpointing an aeroplane’s location from radio transmissions made by its pilots. Though less high profile than radar, the HDUs’ activities allowed the RAF to “see” beyond the range of radar as Luftwaffe bomber formations, transmitting to each other over France, formed up ready for a raid over British soil.
Signals intelligence and compsci
Not far behind radar was the crucial role of what was then the Government Communications and Cipher School (GC&CS), based at Bletchley Park. Today the site is home to the National Museum of Computing but in the dark days of the 1940s it was where codebreakers deciphered German military communications.
Breaking Nazi Germany’s encryption was a vast task, and in the days before computers extremely labour intensive; between 9,000 and 12,000 personnel worked at Bletchley during the Second World War. The demands of RAF and other military commanders for speedy decryption of enemy messages directly contributed to the development of early computer science; Alan Turing worked at Bletchley Park, helping devise improvements to electromechanical crypto-breaking machines that resulted in the Bombe, a very early computer.

Why was Europe better with guns? – The History of Guns
History Clarified
Published 3 Dec 2018China invented gunpowder (combustible powder), so why was it the European nations that went out and conquered the world using firearms?
This video looks at some geographical factors to examine what allowed Europe to innovate while China and most of the world fell behind with gunpowder weapons.
This focuses heavily on Kenneth Chase’s Book, Firearms: A Global History to 1700. He tries to get away from just looking at drill, organization, and state production of firearms to see how geography helped create the necessary conditions for those other innovations.

Durs Egg Ferguson – The Rifle That Didn’t Shoot George Washington
Forgotten Weapons
Published 27 Oct 2018http://www.patreon.com/ForgottenWeapons
Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forg…
Captain Patrick Ferguson was a British officer who designed and patented a breechloading rifle in 1776, which would actually see service in the American Revolution at the Battle of Brandywine. Ferguson presented two rifles to the British military for consideration, one of them being this specific gun. In a shooting demonstration on a windy, rainy day he convinced the Board of Ordnance of the viability of his rifle, and a field trials was set in motion. One hundred Ferguson rifles were made for the Crown, and Ferguson was detached from his regiment to be given command of a company of specially trained elite riflemen. His men were drilled in accurate shooting as well as use of the bayonet, they were organized in small groups to make use of cover and concealment, and they were fitted with green uniforms to blend into the terrain. This unit deployed to the American colonies in 1777, and saw action in the Battle of Brandywine.
Unfortunately for Ferguson and his ideas, the unit didn’t make any particularly notable impact on the battle, although not by any fault of their own. Worse, Ferguson was wounded, and because the unit was so heavily dependent on him it was disbanded while he recuperated. He did see service again at the Battle of King’s Mountain, where he was killed in action. This particular Ferguson rifle was made by the noted London gunsmith Durs Egg, and is one of the two guns presented to the Board of Ordnance that began the whole series of events.

London-Made Lorenzonis Repeating Flintlocks
Forgotten Weapons
Published 26 Aug 2016Sold for $28,750 (for the pair).
A 7-shot repeating handgun before cartridges had been invented? Yep, long before. These two pistols are London-made examples of the Lorenzoni system, in which a gun was made with internal magazines of powder and projectiles and a rotating central loading spindle like a modern reloading powder throw. By rotating a lever on the left side of pistol 180 degrees and back, a shooter could load a ball into the chamber, load powder behind it, recock the action, prime the pan, and close the frizzen all in one automated sequence.
This system originated with a German gunsmith named Kalthoff in the mid 1600s, but it was an Italian by the name of Lorenzoni who made it more practical and began building pistols of the type. Lorenzoni is the name that has been generally applied to the system as a result. These two were made by a gunsmith named Glass in London in the mid 1700s — in those days of hand-made firearms, ideas and systems like this would slowly spread and be adopted by craftsmen who were capable of producing them and thought they could find an interested market for them.
The Lorenzoni system offered unmatched repeating firepower for its time, but was hampered by its complexity. Only a very skilled gunsmith could build a reliable and safe pistol of the type, and this made them very expensive.

John Cabot’s patent monopoly grant and the rise of the modern corporation
In the latest Age of Invention newsletter, Anton Howes traces the line of descent of modern corporate structures from the patent granted to John Cabot to explore (and exploit) a trade route to China:

I discussed last time [linked here] how the use of patent monopolies came to England in the sixteenth century. Since then, however, I’ve developed a strong hunch that the introduction of patent monopolies may also have played a crucial role in the birth of the business corporation. I happened to be reading Ron Harris’s new book, Going the Distance, in which he stresses the unprecedented constitutions of the Dutch and English East India Companies — both of which began to emerge in the closing years of the sixteenth century. Yet the first joint-stock corporation, albeit experimental, was actually founded decades earlier, in the 1550s. Harris mentions it as a sort of obscure precursor, and it wasn’t terribly successful, but it stood out to me because its founder and first governor was also one of the key introducers of patent monopolies to England: the explorer Sebastian Cabot.
As I mentioned last time, Cabot was named on one of England’s very first patents for invention — though we’d now say it was for “discovery” — in 1496. An Italian who spent much of his career serving Spain, he was coaxed back to England in the late 1540s to pursue new voyages of exploration. Indeed, he reappeared in England at the exact time that patent monopolies for invention began to re-emerge, after a hiatus of about half a century. In 1550, Cabot obtained a certified copy of his original 1496 patent and within a couple of years English policymakers began regularly granting other patents for invention. It started as just a trickle, with one 1552 patent granted to to some enterprising merchant for introducing Norman glass-making techniques, and a 1554 patent to the German alchemist Burchard Kranich, and in the 1560s had developed into a steady stream.
Yet Cabot’s re-certification of his patent is never included in this narrative. It’s a scarcely-noted detail, perhaps because he appears not to have exploited it. Or did he? I think the fact of his re-certification — a bit of trivia that’s usually overlooked — helps explain the origins of the world’s first joint-stock corporation.
Corporations themselves, of course, were nothing new. Corporate organisations had existed for centuries in England, and indeed throughout Europe and the rest of the world: officially-recognised legal “persons” that might outlive each and any member, and which might act as a unit in terms of buying, selling, owning, and contracting. Cities, guilds, charities, universities, and various religious organisations were usually corporations. But they were not joint-stock business corporations, in the sense of their members purchasing shares and delegating commercial decision-making to a centralised management to conduct trade on their behalves. Instead, the vast majority of trade and industry was conducted by partnerships of individuals who pooled their capital without forming any legally distinct corporation. Shares might be bought in a physical ship, or even in particular trading voyages, but not in a legal entity that was both ongoing and intangible. There were many joint-stock associations, but they were not corporations.
And to the extent that some corporations in England were related to trade, such as the Company of Merchant Adventurers of London, or the Company of Merchants of the Staple, they were not joint-stock businesses at all. They were instead regulatory bodies. These corporations were granted monopolies over the trade with certain areas, or in certain commodities, to which their members then bought licenses to trade on their own account. Membership fees went towards supporting regulatory or charitable functions — resolving disputes between members, perhaps supporting members who had fallen on hard times, and representing the interests of members as a lobby group both at home and abroad — but not towards pooling capital for commercial ventures. The regulated companies were thus more akin to guilds, or to modern trade unions or professional associations, rather than firms. Members were not shareholders, but licensees who used their own capital and were subject to their own profits and losses.
Before the 1550s, then, there had been plenty of unincorporated business associations that were joint-stock, and even more unincorporated associations that were not joint-stock. There had also been a few trade-related corporations that were not joint-stock. Sebastian Cabot’s innovation was thus to fill the last quadrant of that matrix: he created a corporation that would be joint-stock, in which a wide range of shareholders could invest, entrusting their capital to managers who would conduct repeated voyages of exploration and trade on their behalves.

Nock 6 Barrel Flintlock
Forgotten Weapons

Cool Forgotten Weapons Merch! http://shop.bbtv.com/collections/forg…
Henry Nock was a highly respected and very talented British gunsmith, who manufactured a wide variety of arms including military muskets for the British Army. He is probably best known on the internet for his 7-barreled volley gun (which fires all seven charges simultaneously), intended for naval ship boarding operations. This particular gun resembled that volley gun design, but is actually a self-priming flintlock pepperbox. Its cluster of 6 barrels is manually rotated, allowing the used to fire six separate shots before needing to reload. The priming mechanism and lock bear a remarkable similarity to the Collier repeating flintlocks, and it is suspected that this system was developed by Artemis Wheeler of the United States.

Collier Flintlock Revolvers
Forgotten Weapons
Published 9 Nov 2016Sold for:
First Pattern Musket: $51,750
Second Pattern Rifle: $46,000
Second Pattern Pistol: $63,250Elisha Collier is probably the best-known name in flintlock revolvers — to the extent that any flintlock revolvers are well known. Because of the great cost and required skill to manufacture a functional repeating flintlock handgun without modern machine tools, these weapons were never common, but they were made by a number of gunsmiths across Europe. Collier and a fellow American gunsmith named Artemis Wheeler developed this particular type (the specific contributions of each party are not known), and Collier patented it in England in 1818. He proceeded to market the guns, which appear to have been made for him under contract by several high-end British gunsmiths (including Rigby and Nock).
Collier made three different basic types of guns. They share the main feature of a revolving cylinder which must be indexed manually between shots (seeing them while traveling in India was reportedly the inspiration for Samuel Colt’s idea to connect the mechanical functions of hammer and cylinder to invent the single action revolver). The first two patterns of Collier are flintlocks, differing in lock and cylinder design, as well as having slightly different mechanisms to self-prime. The third pattern was actually made as percussion guns, as Collier’s guns were being made right at the end of the flintlock period and the dawn of the percussion cap. In total, 350-400 guns were made, including 50-100 bought by the British military for use in India.

QotD: The discovery of anaesthesia and antisepsis
The first demonstration of the ether gas was performed at Massachusetts General Hospital in October, 1846, by a Boston dentist, William T. G. Morton. For the first time, surgical operations could be performed painlessly. Within two months, the invention was known and being applied in every capital of Europe, and in little more time it became commonplace internationally. The number of surgical operations vastly increased, as it was no longer necessary to hold patients down, and act very quickly.
Joseph Lister first used carbolic acid (phenol) to perform sterile surgery at the Glasgow Royal Infirmary, in August, 1865. This would have the effect of vastly increasing the survival rate from these now commonplace surgical operations. But the news took years to circulate, and by the twentieth century surgeons were still working with infected equipment in filthy environments. Indeed, I have read accounts of the horrors of battlefield medicine in the First World War: men with survivable injuries, lost by the hundred thousands from ignorant, unnecessarily unhygienic medical procedures.
As Dr Gawande points out — in passing — both advances made life easier on patients. But the second saved lives on a — vastly — greater scale. The first was unique, in making life easier for doctors, who no longer had to operate on screaming, writhing customers. This also, incidentally, hugely increased their trade, and thus their income. Washing up, effectively, only added nuisance.
I already knew this history — my mommy was a ward matron, after all — but until the comparison was spelt out, the full significance was lost on me. I had read the “official” versions in several standard medical histories. They assume the slow spread of antisepsis was a problem of communications. Gentle reader will note that this is a lie. Methods of communication did not slow in the generation between the two inventions.
