The science of “shaken, not stirred”

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 pre-history of Halloween

In History Today, Maggie Black looks at the origins of current Halloween traditions:

…the feast which the early Church took [over] most completely from the great pagan, Celtic feast of Samhain which celebrated the end of summer and the harvest, together with the start of winter and the New Year. The Celts believed that, on the eve of the festival (our own Hallowe’en), the dead returned to walk the earth for a night and a day and with them came the spirits of evil, at their most potent. Fires blazed on every hilltop to purify the land, defeat the evil ones and encourage the wasting sun to revive. Ceremonial dancing, noisy games and harvest-end rituals took place around these fires with drinking of the herbal ales for which the Celts were renowned. Seizing their chance to question as well as to honour and propitiate their dead, the Celts chose this time for divination rituals too.

The force and vigour of the ancient beliefs overrode all newer ones and these practices survived the advent of Christianity, in barely translated form at first, and only very gradually died out. The evil spirits became witches, and the bonfires burned them in effigy (for instance the Shandy Dann at Balmoral where, we are told, Queen Victoria much enjoyed the fun). A great number of divining rituals and games, often involving apples, nuts and fire, persisted; apples and nuts were the last-harvested fruits. Even the old herbal ale: survived as mulled ale or punch with roasted apples floating in it.

The more significant pre-Christian practice of impersonating the dead and other spirits and by so doing protecting oneself and others from their spectral power also continued. Sometimes this was acted out by processions of young adults (later children) wearing or carrying grotesque masks and often headed by a youth carrying a horse’s skull (as, for example, the Lair Bhan in co Cork, or the Hodening Horse in Cheshire). They went from door to door or visited friends and neighbours, collecting money for food. Before Christian times, such largesse had no doubt been given to feast the dead spirits in return for the promise of fertility and protection from evil provided by the visit. But in pre-Reformation Christian Europe, it provided candles and masses for the dead and snacks for the living.

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

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).
