Tomb discoveries cast light on Thracian culture

Filed under: Europe, History, Science — Tags: , , , , — Nicholas @ 10:16

A recent discovery in Bulgaria promises to tell us more about the culture of the Getae, a powerful tribe in Thrace:

Archaeologists in Bulgaria are chuffed today to announce that golden treasures and artifacts produced by the ancient Thracians have been discovered in a subterranean tomb complex in the north of the country.

The treasures include snake-headed bracelets, a golden crown or tiara type affair, a golden horse head and piles of smaller solid gold items including rings, statuettes and buttons. They’re thought to date from the third century BC and to have been produced by the Getae, a tribe among the ancient Thracians.

[. . .]

Thracian warriors played prominent parts in many of the wars of antiquity. The peltast javelineer style of fighting was said to have originated in Thrace, gradually superseding the armoured hoplite warrior: an entire phalanx of the formidable Spartans was crushed by peltasts fighting for Athens during the Peloponnesian War, and the lightly armoured Greek/Thracian warriors are also said to have inflicted severe damage on heavy Persian cavalry.

Alexander the Great — from the neighbouring area of Macedonia — is also said to have used Thracian mercenaries in his world-spanning campaigns, and later on Thracian warriors were prominent in the armies of Rome and then the Eastern empire. In particular, the famous gladiator and rebel Spartacus had originally been a Roman auxiliary soldier from Thrace. Later on — after the fall of Rome, when the Empire was ruled from Constantinople — both the emperor Justinian and the great general Belisarius are said to have been Thracians.

The Swiss children of Malthus

Filed under: Environment, Europe, Politics — Tags: , , , , , — Nicholas @ 08:59

In sp!ked, Patrick Hayes points out the odd way that Malthusians and xenophobic far-right political groups converge:

For greens, the ends will always justify the means when it comes to saving the planet. In the UK, they have opportunistically latched themselves on to left-wing movements to try to gain purchase with a broader public. But, as Swiss campaign group Ecology and Population (EcoPop) has demonstrated, in an attempt to pursue their Malthusian goals, greens can be equally happy tapping into the anti-immigrant rhetoric of the far right.

In a stunt last week, members of EcoPop carried dozens of cardboard boxes into the Swiss chancellery which contained 120,700 certified signatures calling for immigration into Switzerland to be capped at 0.2 per cent of the resident population. Under Swiss law, this means that a referendum will now be held on the proposal. Such a move trumps even the efforts of the far-right Swiss People’s Party, which has long lobbied for greater immigration controls.

But these greens aren’t mobilising for an immigration clampdown with banners claiming ‘keep the darkies out’ as right-wing groups have done in the past. Nor are they using dodgy, discredited scientific arguments to justify racial superiority, wielding books like Madison Grant’s The Passing of The Great Race for evidence.

No, instead EcoPop delivers its demands for immigration curbs carrying a banner asking: ‘How many people can the Earth tolerate?’ The group’s members use the (equally dodgy and discredited) Malthusian science of population growth and babble on about our ‘finite planet’. And they have reportedly been strongly influenced by the theories of US Malthusian Paul Ehrlich, author of The Population Bomb.

EcoPop bends over backwards to claim that it is not singling out particular races when advocating its policies. According to the BBC, it claims to be ‘opposed to all forms of xenophobia and racism’. But, the group says, ‘Switzerland must limit immigration to avoid urbanisation and to preserve agricultural land’.

You could almost believe that EcoPop is just a bunch of backward-thinking NIMBYish Luddites wanting to stop a flood of immigrants from destroying what it sees as a rural idyll — until you see what the group has tacked on to its proposed referendum for immigration caps. EcoPop slipped an additional clause into the referendum calling for a tenth of all foreign aid to be used ‘for birth-control measures abroad’. (It’s highly questionable how many people would have signed a petition for that alone.)

So it’s not enough to keep foreigners out of Switzerland, then, it’s also necessary to keep them from breeding too much in their own countries as well. And the fact that most of the aid will go towards stopping poor black and brown families from breeding too much suggests that if they’re not intentionally being racist, then EcoPop’s members should really think very hard about how they come across.

Matt Ridley on the real threat to our ecology

Filed under: Britain, Bureaucracy, Environment — Tags: , , , — Nicholas @ 00:01

It’s not global warming:

I’m pessimistic about the ash trees. It seems unlikely that a fungus that killed 90 per cent of Denmark’s trees and spreads by air will not be devastating here, too. There is a glimmer of hope in the fact that ash, unlike elms, reproduce sexually so they are not clones — uniformly vulnerable to the pathogen. But it’s only a glimmer: tree parasites, from chestnut blight to pine beauty moth, have a habit of sweeping through species pretty rampantly, because trees are so long-lived they cannot evolve resistance in time.

The Forestry Commission’s apologists are pleading ‘cuts’ as an excuse for its failure to do anything more timely to get ahead of the threat, but as a woodland owner I am not convinced. An organisation that has the time and the budget to pore over my every felling or planting application in triplicate and come back with fussy and bossy comments could surely spare a smidgen of interest in looming threats from continental fungi that have been spreading out from Poland for 20 years. The commission was warned four years ago of the problem.

Here’s what the commission was up to instead. Just last year, I received a letter from the Forestry Commission demanding access to survey one of my woods to answer the question ‘what are the forecasts for timber, biomass and carbon?’ in order to ‘help the United Kingdom meet international commitments, such as reporting for the Global Forest Resources Assessment and the Ministerial Conference on the Protection of Forests in Europe (MCPFE)’.

Notice the Sir Humphrey-esque circular argument: surveys must be done so that the results can be reported to assessment meetings. In other words, as far as I can tell, the Forestry Commission’s priority has been, as in so many government bodies, to supply talking points for the international carbon-obsessed bureaucracy. The implicit assumption here, of course, is that climate change is the greatest threat to Britain’s trees, when in reality far greater threats come from diseases carried around by foresters themselves.

This is happening throughout the world of nature conservation. A climate fetish has sucked all the oxygen from the real threats to species and habitats — indeed it has actually begun to make those threats worse.

Even “Biblical views” change over time

Filed under: Health, History, Religion, USA — Tags: , , — Nicholas @ 10:39

An older post, but still rather informative:

The ‘biblical view’ that’s younger than the Happy Meal

In 1979, McDonald’s introduced the Happy Meal.

Sometime after that, it was decided that the Bible teaches that human life begins at conception.

Ask any American evangelical, today, what the Bible says about abortion and they will insist that this is what it says. (Many don’t actually believe this, but they know it is the only answer that won’t get them in trouble.) They’ll be a little fuzzy on where, exactly, the Bible says this, but they’ll insist that it does.

That’s new. If you had asked American evangelicals that same question the year I was born you would not have gotten the same answer.

That year, Christianity Today — edited by Harold Lindsell, champion of “inerrancy” and author of The Battle for the Bible — published a special issue devoted to the topics of contraception and abortion. That issue included many articles that today would get their authors, editors — probably even their readers — fired from almost any evangelical institution. For example, one article by a professor from Dallas Theological Seminary criticized the Roman Catholic position on abortion as unbiblical. Jonathan Dudley quotes from the article in his book Broken Words: The Abuse of Science and Faith in American Politics. Keep in mind that this is from a conservative evangelical seminary professor, writing in Billy Graham’s magazine for editor Harold Lindsell:

    God does not regard the fetus as a soul, no matter how far gestation has progressed. The Law plainly exacts: “If a man kills any human life he will be put to death” (Lev. 24:17). But according to Exodus 21:22-24, the destruction of the fetus is not a capital offense. … Clearly, then, in contrast to the mother, the fetus is not reckoned as a soul.

Christianity Today would not publish that article in 2012. They might not even let you write that in comments on their website. If you applied for a job in 2012 with Christianity Today or Dallas Theological Seminary and they found out that you had written something like that, ever, you would not be hired.

At some point between 1968 and 2012, the Bible began to say something different. That’s interesting.

Even more interesting is how thoroughly the record has been rewritten. We have always been at war with Eastasia.

The science of “shaken, not stirred”

Filed under: Books, History, Media, Science — Tags: , , , — Nicholas @ 09:05

Ah, those dedicated researchers at The Register! This time, they’ve got Gavin Clarke looking into the famous dry martini of James Bond:

“A distressingly large amount of rubbish is talked about cocktails,” Noel Jackson, top boffin at the Life Science Centre in Newcastle-Upon-Tyne, tells The Reg.

Jackson, a Cambridge-University-educated chemist, has all the straight-up science on alcohol.

“We do a lot of debunking of things that people think are true,” he tells us. “There’s this business of shaken versus stirred. Once you heard it said from people in the cocktail world that shaking ‘bruises’ a liquid! That’s rubbish.”

The Reg, as part of our ongoing celebration of James Bond’s fiftieth year on film, was talking to Jackson about one of the signature elements of the 007 package: the dry vodka martini. Shaken, not stirred.

Jackson comes on the best of recommendations. We were put onto him by the boffins of the UK’s National Physical Laboratory, who have been instrumental in such developments as packet-switched networking and the “Dambuster” bouncing bomb of World War II fame.

“What he doesn’t know about drinks, doesn’t need to be known,” they told us.

We spoke to Jackson about chemicals and thermal dynamics. We start with flavour, and that means talking alcohol.

The economic problem with recycling is that it’s the inverse of retail value

Filed under: Economics, Environment, Technology — Tags: — Nicholas @ 00:01

Tim Worstall at Forbes:

We all understand how pricing in the retail chain goes. Each unit of something in a shipload of them is worth less than each unit when there’s only a container of them, and so it goes on. As we get closer to the retail point each unit rises in value. As we break down the shipment from tens of thousands of units, to a truckload, then a pallet load, finally to the one single item sitting on the store shelf. If you agree to purchase 5,000 iPads you’ll expect to pay less for each one than if you tried to buy just one.

We get that: the thing about recycling is that pricing works entirely the other way around. To a reasonable approximation the value of one unit of anything for recycling is worth nothing. The value of each of 1,000 units in the same place is higher than that solitary one. One scrap car in the middle of a field isn’t worth much if anything. 1,000 cars in a scrap yard might be worth $300 a tonne for the steel content (don’t take these numbers too seriously by the way, they’re examples only). Precious metals refining, scrap metal, recycling: they all share this same economic point. The more of something you have then the more each unit of that something is worth.

[. . .]

… the way we tend to look at the economics of recycling. We hear a great deal about how recycling plastics, or cooking oil, metals, electronics, you name it we hear the same thing, “saves resources”. Sometimes this is absolutely true. Other times however what we get shown is the value of the actual recycling being done. And we’re not told about the costs of collecting what is to be recycled. And as above it’s those costs of collection that are really the key to the whole enterprise.

Just as an example there’s value in 1,000 tonnes of used plastic bags. Among other things you can burn them in a power station and get some energy. Great: but what is the cost of collecting enough used plastic bags to make 1,000 tonnes? That’s the part that seems not to get into the calculations that our green friends present to us.

Cash4Gold seems to have gone under because the collection costs of the materials were higher than the value of recycling those materials. What’s really rather worrying about the larger recycling movement is that this can be/is often true of other materials. But because we don’t properly account for the collection costs we don’t see this as clearly as we do in the accounts of a (failed) for profit company (OK, would be for profit company).

Pushing for “medical marijuana” makes full legalization less likely

Filed under: Health, Law, Liberty, USA — Tags: , , , , , , , — Nicholas @ 09:05

L. Neil Smith makes the point that supporters of medical marijuana may be missing:

What I do mind — and perhaps I am alone in this, who knows? — is weak and disingenuous politics with regard to drugs. It was the issue of “medical marijuana” that first got my goat this way. I don’t doubt for a microsecond that the weed makes life easier and longer for those suffering certain diseases, and I believe that those who would deny them that relief are little better than scavengers on the misery of others.

But observation — and my knowledge of history and human nature — suggests that the majority of those who advocate the legalization of pot “purely for medicinal purposes” do not require it for that reason. They simply want to slip the nose of their personal camel under the edge of the tent, and I find that approach sneaky, dishonest, and cowardly.

I believe that if they had spent the past fifty years pushing the Ninth Amendment right to roll up and smoke whatever frigging vegetable you wish, marijuana would be legal now, and there would not have been a “War On Drugs” handy for the psychopathetic enemies of liberty to transform into a War on Everything, including the American Productive Class.

I think we’ve seen the high point for medical marijuana. The proof of that lies in a current initiative to “Regulate Marijuana Like Alcohol”, on the ballot in my home state of Colorado this year. The title says it all, although the details could be gruesome, ending in a mess found in some states and all military bases, where the government runs the liquor stores (about as well as they run everything else). In the Air Force, when I was growing up, some officious snoops regularly examined the records of the store and your commanding officer would get a tattletale letter if they thought that you were buying too much booze.

Whatever that amounts to.

This is not a kind of progress any that real libertarian would recognize. The fact that advocates of the measure make a major selling point of taxing the stuff only makes it worse, both in principle and practice. First, by what right does anybody steal money from me when I choose to spend it on some things and not on others. Furthermore, when I was just entering college, a smoker could buy a pack of Marlboros out of a machine for 35 cents. Today, the price per pack is nudging five dollars, and only a small fraction of that is attributable to inflation.

Exactly the same thing will happen with marijuana.

The Dragon returns, bearing cargo

Filed under: Business, Space, Technology — Tags: , , , , — Nicholas @ 09:37

At The Register, Brid-Aine Parnell reports on the mostly successful cargo delivery round-trip by SpaceX’s Dragon capsule:

The reusable cargoship dropped into the ocean yesterday evening around 250 miles off the coast of Mexico after resupplying the ISS and its crew. The Dragon was ferried to a port near Los Angeles where it will be prepped for its return to SpaceX’s test facility in Texas.

Some of the cargo brought back by the capsule is due to be returned to NASA in the next couple of days, including research samples from the station’s microgravity environment. The ship delivered 882 pounds of gear to the ISS, including scientific research and crew supplies. It returned with nearly twice that weight of stuff.

The mission was only a part-success, as the secondary objective was to launch a satellite for Orbcomm, but due to a malfunctioning engine in the launch phase, the satellite could not be placed in the correct orbit and was lost. Orbcomm is sticking with SpaceX for two more satellite launches in spite of this initial failure.

Twenty million broken windows

Filed under: Economics, Environment, Media — Tags: , , — Nicholas @ 09:03

At Forbes, Tim Worstall patiently explains that the damage from Hurricane Sandy (or any major storm) will appear to boost GDP, because it only measures money spent to repair damage, not the costs incurred or the opportunities foregone because of the damage:

We know very well that Hurricane (or Frankenstorm as some are calling it) Sandy will leave a trail of destruction across parts of the US today. There will almost certainly be deaths, as there have been in the hurricane’s passage across the Caribbean. And there will also be a boost to the US economy. Which is really evidence of quite how wrong we are in the way that we measure the economy.

[. . .]

The problem with this is that it is only true because of the way that we calculate GDP. In our working of the numbers we assume that it’s final consumption at market prices: that is, the value that consumers put on everything. However, this is not true of government spending. It’s very difficult indeed to work out what government spending is actually worth: for as we’ve not a choice in it then there’s no market price nor accurate valuation from the people who actually get whatever is produced. Some government spending is most certainly worth more than the actual amount spent. The court system say: a pre-requisite of our having a complex society at all. Other parts not so much: what is the true value of a diversity adviser for example? So what we actually do is value all government spending, for GDP purposes, at the cost of that actual spending. Government spends $100, GDP goes up by $100. That’s just how we define it. This can cause amusement in measuring the success of welfare programs for example. Even Census admits that some of the people who receive Medicaid, or food stamps, value what they receive at less than the cost of providing it.

[. . .]

Now imagine that Hurricane Sandy does $10 billion of damage to that wealth (for our purposes it doesn’t matter whether it’s $100 billion or $1 trillion. Although this obviously matters to everyone except for the purposes of this example). The US is now worth $99.990 Trillion. GDP might rise to $15.1 trillion as we repair that damage. But we’re not in fact any richer at all: despite the fact that GDP has gone up. What has actually happened is that some of our stock of wealth has been destroyed and we’re having to do more work in order to rebuild it. This is exactly the same as our pollution example. We’re measuring what we produce but not the capital stock of what we have (or had).

Yes, the rebound from Sandy may well provide a boost to the economy. But that’s a function of the way that we measure that economy, not a real boost in our general wealth.

Got Milk (mutation)?

Filed under: Environment, Food, Health, History, Science — Tags: , — Nicholas @ 12:33

Lactose intolerance is part of humankind’s genetic inheritance, which is why the mutation that allowed (some) adult humans to digest milk is of great interest to geneticists:

A genetic mutation appeared, somewhere near modern-day Turkey, that jammed the lactase-production gene permanently in the “on” position. The original mutant was probably a male who passed the gene on to his children. People carrying the mutation could drink milk their entire lives. Genomic analyses have shown that within a few thousand years, at a rate that evolutionary biologists had thought impossibly rapid, this mutation spread throughout Eurasia, to Great Britain, Scandinavia, the Mediterranean, India and all points in between, stopping only at the Himalayas. Independently, other mutations for lactose tolerance arose in Africa and the Middle East, though not in the Americas, Australia, or the Far East.

In an evolutionary eye-blink, 80 percent of Europeans became milk-drinkers; in some populations, the proportion is close to 100 percent. (Though globally, lactose intolerance is the norm; around two-thirds of humans cannot drink milk in adulthood.) The speed of this transformation is one of the weirder mysteries in the story of human evolution, more so because it’s not clear why anybody needed the mutation to begin with. Through their cleverness, our lactose-intolerant forebears had already found a way to consume dairy without getting sick, irrespective of genetics.

[. . .]

A “high selection differential” is something of a Darwinian euphemism. It means that those who couldn’t drink milk were apt to die before they could reproduce. At best they were having fewer, sicklier children. That kind of life-or-death selection differential seems necessary to explain the speed with which the mutation swept across Eurasia and spread even faster in Africa. The unfit must have been taking their lactose-intolerant genomes to the grave.

Milk, by itself, somehow saved lives. This is odd, because milk is just food, just one source of nutrients and calories among many others. It’s not medicine. But there was a time in human history when our diet and environment conspired to create conditions that mimicked those of a disease epidemic. Milk, in such circumstances, may well have performed the function of a life-saving drug.

Toronto accused of being deadly waypoint for migratory birds

Filed under: Cancon, Environment — Tags: , , — Nicholas @ 12:11

In the New York Times, Ian Austen examines claims that Toronto’s downtown core is taking a huge toll of migratory birds every year:

There is no precise ranking of the world’s most deadly cities for migratory birds, but Toronto is considered a top contender for the title. When a British nature documentary crew wanted to film birds killed by crashes into glass, Daniel Klem Jr., an ornithologist at Muhlenberg College in Allentown, Pa., who has been studying the issue for about 40 years, directed them here, where huge numbers of birds streaking through the skies one moment can be plummeting toward the concrete the next.

“They’re getting killed everywhere and anywhere where there’s even the smallest garage window,” Professor Klem said. “In the case of Toronto, perhaps because of the number of buildings and the number of birds, it’s more dramatic.”

So many birds hit the glass towers of Canada’s most populous city that volunteers scour the ground of the financial district for them in the predawn darkness each morning. They carry paper bags and butterfly nets to rescue injured birds from the impending stampede of pedestrian feet or, all too often, to pick up the bodies of dead ones.

The group behind the bird patrol, the Fatal Light Awareness Program, known as FLAP, estimates that one million to nine million birds die every year from impact with buildings in the Toronto area. The group’s founder once single-handedly recovered about 500 dead birds in one morning.

Rob Silver finds the claim to be a bit unlikely:

Chemophobia, “a fear so rampant that it has infected an entire generation of women”

Filed under: Environment, Health, Media — Tags: , , , — Nicholas @ 12:13

Margaret Wente in the Globe and Mail:

Ms. Williams is right that our bodies contain trace amounts of pretty much everything that’s in our environment. But toxicity is a matter of degree. And technology is so advanced that we can measure trace amounts in parts per trillion. As yet, research has found no trace of harm. For example, after a comprehensive review of environmental causes and risk factors for breast cancer, the U.S. Institute of Medicine found no conclusive link between any of these chemicals and an increased risk of breast cancer. According to Scientific American, “some research shows the toxic load in breast milk to be smaller than that in the air most city dwellers breathe inside their homes.”

[. . .]

This is not to say there’s no impact from environmental factors. But these effects are small and uncertain. To eliminate them all, we’d have to eliminate modernity and return to being hunter-gatherers again.

But I’m afraid chemophobia is here to stay. Fear sells. Fear of chemicals manufactured by rapacious, greedy, money-sucking capitalist enterprises sells even better. Fear is is the main product peddled by interest groups such as the Environmental Defence Fund, which has been quite successful at marketing the notion that invisible dangers lurk all around us. The media love this stuff because it makes for easy headlines: If your shampoo doesn’t kill you, your lipstick will! Fear is a staple of celebrity experts like Dr. Oz, who has advised readers to avoid toxic sales receipts from fast-food restaurants and gas stations.

Want to learn a new language? How about proto-Elamite?

Filed under: History, Middle East, Science — Tags: , , , — Nicholas @ 09:10

If you have the ability to decode the world’s oldest undeciphered texts, you can be our first proto-Elamite scholar:

“I think we are finally on the point of making a breakthrough,” says Jacob Dahl, fellow of Wolfson College, Oxford and director of the Ancient World Research Cluster.

Dr Dahl’s secret weapon is being able to see this writing more clearly than ever before.

In a room high up in the Ashmolean Museum in Oxford, above the Egyptian mummies and fragments of early civilisations, a big black dome is clicking away and flashing out light.

This device, part sci-fi, part-DIY, is providing the most detailed and high quality images ever taken of these elusive symbols cut into clay tablets. This is Indiana Jones with software.

It’s being used to help decode a writing system called proto-Elamite, used between around 3200BC and 2900BC in a region now in the south west of modern Iran.

And the Oxford team think that they could be on the brink of understanding this last great remaining cache of undeciphered texts from the ancient world.

QotD: Environmental externalities

Filed under: Economics, Environment, Quotations — Tags: , , , , — Nicholas @ 11:12

That other people place different values upon the environment than I do worries me not in the slightest. It is precisely such differences of opinions about value that make a market. What does annoy me intensely is that almost all of the environmental problems that are currently being complained about have indeed been studied by economists. And they’ve found solutions to them as well. Just about any and every environmental problem is either about externalities or common access to a resource. In many ways these are just the flip side of exactly the same problem. But we do indeed know how to solve each of them and both of them. Hardin on ownership or regulation, Pigou on tax or regulation, both mediated through Coase on transactions costs (with a decent assit from Ostrom on communal ownership). There, that’s it: far from economics ignoring matters environmental economics has solved the damn problems.

So why won’t the environmentalists listen?

Elon Musk drops hints about next SpaceX development direction

Filed under: Space — Tags: , , , , , — Nicholas @ 00:03

Zach Rosenberg reports on the next big thing we can expect from SpaceX:

Launcher developer SpaceX has promised a new engine for a new rocket, larger than the Falcon 9 that NASA expects to become a mainstay of its Earth orbit operations.

Elon Musk, the Silicon Valley entrepreneur who successfully parlayed the fortune he earned founding PayPal into launch systems developer SpaceX, said the new engine would not be based on the 160,000lb-thrust (712kN) Merlin 1 series that powers Falcon 9.

Musk said the new rocket, which he calls MCT, will be “several times” as powerful as the 1 Merlin series, and won’t use Merlin’s RP-1 fuel. Beyond adding that it will have “a very big core size”, he declined to elaborate, promising more details in “between one and three years”.

Musk declined to say what ‘MCT’ stands for, and declined to answer further questions on the project.
