Ariadne auf Portesmuða

 In 1960 when I was ~6, I lived for a year in the “Captain’s House, HMS Verno, Potmouth” which tells you that my spelinge was as shockin’ poor as my hand-writing. HMS Vernon, Portsmouth is now a shopping centre but in 1960 it was part of the Royal Navy. It was a Shore Establishment where they trained sailors – both officers and men – in the fine art of mine-sweeping. My father, was the Top Dog at HMS Vernon. We’d occasionally be walking in his company through his domain. He had his peculiarities, my Dad, and he hated to see flags wrapped round flag-poles, especially if wet and sticky. They had to be either a) flapping brightly in the breeze or b) hanging limp beside the flag-staff if there was no wind. English weather is a mix of wind, rain, calm and occasional sunshine. If he saw a rain-wet flag clagged up against or around the pole he’d shout at the nearest fellow in a uniform to “Clear that flag”. The poor sailor had to work out what would please the cross-sounding 👿 who was on his case. Usually, this required hauling down the flag, resetting it at the mast-head, and hoping The Old man would go away; at least until the poor squaddie was somewhere else – preferably in the canteen, out of the rain, having a cup of tea and a biscuit.

Right opposite the door to our house was a double-life-size figurehead salvaged from the bows of HMS Ariadne when that 19thC 26-gun frigate had finally been sent to the breaker’s yard in 1922. She looked a lot brighter in colour. The grassy area behind the figurehead is where I learned to ride a bicycle. It’s better to learn to ride on a road than on grass because staying upright depends upon inertia and going fast and it’s easier to get up to speed if the surface isn’t slippy and buckety.

Q. Why would you call a ship Ariadne?
A. Because Ariadne is famous in tale and story.

I used this as an introduction to a tall tale of Antient Crete which I wrote last month for Gdau.I: The Ariadne story needs an upgrade and she also needs a couple of sidekicks as supporting actors and choru♪. Somebody has to make the tea!

It turns out that HMS Ariadne is not just another work-a-day naval vessel after she was launched at Deptford in 1859. In June 1872, at Gibraltar, a sailor fell off the mast in a gale and the captain hove-to in order to affect a rescue. After a fruitless search, the cutter was recalled but broached to and was swamped. A second boat was launched to rescue the rescuers but one of the falls fouled when this craft hit the water and tipped the whole of that crew into the drink. The thing about launching boats from davits is that it requires excellent training and precise timing to release the boat at both ends simultaneously . . . even if there is a full gale blowing and a frightful sea running. All told 11 sailors perished that morning. Attention was drawn, in the letters pages of The Times, that nobody was wearing life-jackets. Also noted was there was a solution to the falls fouling in the form of a patent release-mechanism developed years before After a similar tragedy, the late Mr. C. Clifford, who had long bestowed the most earnest attention to the subject, perfected an exceedingly simple and efficient method of lowering a ship's boats in a few seconds, irrespective of the weight or size of the boat, or whether laden with its full crew or containing only one man. The lowering could be accomplished, too, and by a lad, just as easily whether the vessel were at anchor in a harbour or under a full press of sail or steam, and in a heavy sea. Regrettably, the Admiralty had not mandated this nifty piece of kit throughout the fleet.  Riding a bicycle is not the only thing involving inertia!

St Martin of Island

 I've been a bit of a fan of St Martin of Tours for his cloak sharing ways. And I've found all things Nederlands gezellig since I spent the Summer of '76 in Wageningen, watching the Tour de France, doing some ornithology, and learning the rudiments of the language. And here is the Venn diagram intersection between those two threads in my life's tapestry:


The island of San Martin was discovered by Cristóbal Colón a genocidal slaver and racist in the employ of Los Reyes Católicos Fernando II de Aragón & Isabel I de Castilla. Actually, the 11 November 1493 anchorage, which sheltered the ships of Columbus was probably Nevis but geolocation was sketchy enough in those days that the St Martin's Day island drifted north and attached itself to the Leeward Island of which we treat. And just so you know where everything is. The Leewards are (for NW to SE):

  • Virgin Islands 
  • Anguilla 
  • Saint Martin/Sint Maarten 
  • Saint-Barthélemy St Barts
  • Saba 
  • Sint Eustatius 
  • Saint Kitts 
  • Nevis
  • Barbuda 
  • Antigua
  • Montserrat 
  • Guadeloupe 

                        The French and the Nederlanders have been sharing the island as a condominium for nearly 400 years and the border took about half that time to settle into the current 60:40 split. Because both parts of the island are constituent parts of their European motherships, the grens/frontière has become an enigmatic pub-quiz question because for most of political space Belgium elbows between the two countries. Whereas in the Caribbean you can stroll across the border without your passport. If you want an actual condominium on the island, you'll need more than $1,000,000 . . . unless you want to be cheap. Cheap thrills? As far as youtube is concerned the only thing worth doing on the island is getting blasted by partly burned aviation kerosene where the airport fence meets the beach. 

                        The two endemic species Calyptranthes boldinghgii a Fuchsia-like shrubbery & Galactia nummelaria, a legume are both probably extinct. The white sandy beaches depend upon seagrasses like Paddle Grass (Halophila decipiens), Manatee Grass (Syringodium filiforme) and especially, Turtle Grass (Thalassia testudinum) to stabilise the offshore seabed [prev elsewhere] in hurricane season and the mangroves are fighting a rearguard action against the demands of yachties for more anchorage.

                        Go to goaty

                        Friends [home-ed, Birkenstocks, rice-cakes, GIY] of ours kept goats when their kids were small. The milk was acceptable so long as it was super fresh and cold. After a day or two, even in the fridge, the girls would screw up their faces at the whiff. That same child-challenging aroma is what makes goat cheeses an interesting addition to the cheese-board. There are three medium-chain fatty acids whose name is derived from Capra hircus. Fatty / carboxylic acids all have a carboxyl COOH group at one end which is quite reactive and dietary "fat" typically attaches the COOH to glycerol leaving a chain of hydrocarbon hanging off the end. 

                        • capric acid aka decanoic acid has ten carbons [MP 31°C]
                        • caprylic acid = chain 8 C long [MP 16°C]
                        • caproic acid = chain 6 C long [MP -4°C]

                        All three of these goaty fatty acids are "saturated" - all the carbons are fully charged with hydrogens. Saturation and length both contribute to solidifying the acids and their compounds. The melting points in the list above imply a linear relationship between chain length and MP, but it's more complicated than that with acetic acid being solid at roomish temperature. Unsaturated fats have double bonds between some of the carbons making them a bit more flexible and less viscous. For completeness, I've mentioned SCFAs in a takedown about the number of diets which depend more on assertion than evidence. SCFAs have fewer carbons in the side chain: formic C; acetic CC; proprionic CCC; butyric CCCC [as in butter]; valeric CCCCC.

                        Mammal milk is widely different in fat content, let alone exactly what fatty acids are present, and there is some evidence that MCFAs are anti-fungal and/or pre-biotic - encouraging the growth of good gut bacteria. Capric acid is also found in plants; especially coconut [10%].  If you have a well-trained microbiome, then high fibre diets will naturally ferment to produce a) SCFAs and b) gas. If you are a) 12 years old b) a boy it is therefore acceptable to talk about short chain farty acids. Note kids are adorable.

                        The Earth moved

                        Last weekend, What3Words, a cunning geolocating scheme which divides the whole surface of the blue planet into 57 trillion [5.7 x10^13] squares about the size of a carpet [3m x 3m], loomed over my event-horizon and I shared the coordinates of our front door with the family. I got there by entering our Eircode on the W3W search map. As I've said before, my whole life - or the bits that I can remember - is recorded in The Blob. I try to not repeat exactly the same anecdote at different times. So I searched the Blob archive having more or less forgotten that I'd been there/here before: three years ago, I was all excitey about W3W and I reported then that you could find me at provide.deluxe.interlude. But that's not where we live, unless I'm slinging a hammock between two bay-trees in our back-garden.:


                        The red square is provide.deluxe.interlude, which AFAIR was nearest our front door in 2018. Somehow the W3W grid has shifted about 20m north w.r.t. Google maps in the 40 months since I last checked.  That sounds a lot but note that the North magnetic pole is sprinting across the globe at a rate of 50km/year. In my youth it was shimmying about among Canada's Arctic Island, but in 2019 it grazed the actual North Pole and is now in the process of defecting to mother Russia. 

                        Mais revenons à nos moutons Irlandaises - you can see six of the them grazing in our haggard. If we kept better records [as required by our masters in the Dept Agriculture, hmmmm], we'd be able to pin-point the week when the "CNES Airbus Maxar Technologies" satellite snapped a pic of our property without asking permission. It is amazing the resolution achieved and the Terabyte load must be such a weight on The Cloud as to induce rain. If I'd had notice, I would have waved or mowed a greeting in the lawn.  Of course, I went off stalking all my friends-and-relations but the pixel quality of their gaffs were nowhere near as crisp as ours.

                        Now here's another discrepancy. In March and April this year, I was fossicking about on the far side of our commonage trying to reconcile several sources of cartographic data including Barry Dalby's 1:25,000 map and townlands.ie with the actual landscape under my feet. Dalby has chosen to exclude all political boundaries [county, parish, townland] from his map but has captured tracks, drains and ditches which are almost invisible from eye-level. A bold black line trending north appears on Dalby's map which I found to be a straight line depression which is rather greener, because wetter, than the surrounding heathland. My hypothesis was that this was a) the work of sleán and human arm b) a sort of Offa's Dyke demarcating the county line back in the days when such things mattered. But on the W3W map [R], the County line is offset two squares to the East of the shadowed line of the dyke / drain / ditch or . . . about 20m N if you choose to superimpose the lines in that way. Same as our front door.

                        One supercool advantage of W3W over Eircodes for geolocating in Ireland is that Eircodes only recognise premises - homes and businesses with a roof, like. Not much good if your car breaks down and there are no houses visible. In February last year four hopelessly under-clothed tourists were located and carried off the flanks of Ben Nevis in a blizzard. They were fortunate to a) have gotten a signal in that benighted spot b) had the W3W app installed and so were able to communicate their location +/- 3m [or 20m?] to the mountain rescue team. Eircodes / UK postcodes would have been much less use there than a proper hat and gloves.

                        The World is a doughnut.

                        Thirty years ago economist Richard Dowthwaite published a book with a great title The Growth Illusion; so great that I went off and bought a copy. In 1991, we really hadn't a clue; we'd just got off the boat from England; and I had just started in a new field under a boss with exacting high standards. Having watched the 1984 Miner's Strike from the sidelines and not bought shares in British Telecom, I knew there was something wrong about the economic model which was being embraced in these WEA islands: the market is king; there is no such thing as society. I guess I hoped Douthwaite would put structure on my inchoate concerns about GDP growth vs a finite planet. Massive fail: I just couldn't get past about p.5 it was so dull and alienating. I must have given my copy of The Growth Illusion away because it is no longer glaring down at me reproachfully from the bookshelf.  The seed was ready but the soil was stony. 20thC economists thought economies were circular [R]:the main driver was the upper cycle: workers would get up in the morning  and clock-in for wages. At the weekend they'd buy stuff to sustain the factories and boutiques and cinemas which were employing them. 

                        With a pinch of desperation, last week I downloaded Doughnut Economics: seven ways to think like a 21st century economist by Kate Raworth from Borrowbox. This is much better as an analysis of what's wrong with Capitalism and where we might go next . . . or maybe I've grown up enough to understand what it means. Raworth identifies two elephants on this economic merry-go-round a) The engine is missing: the energy [black gold] and natural resources from which goods are made are treated as infinite and available. b) Who makes the toast and washes the dishes - and the shirts, the car and the front stoop? The worker with his labour and his lunch-pail needs the invisible [unpaid anyway] support of his family. Yes yes pronoun alert: but still 73 years after the publication Paul Samuelson's Economics the worker is male and he's gorra wife,  We hear a lot about the squeezed middle: the productive backbone of society who are too rich to get a medical card but too poor to afford private health insurance. Raworth's economy is squeezed between the demands of people for a bright plastic basin to wash the dishes in [and the water to suds with] and the now suddenly finite resources of spaceship Gaia:


                        Raworth's economy is subtitled a safe and just space for humanity. The Market economy is quite happy to have emaciated kids rivetting eyelets onto Nike trainers because those kids are prepared to work for $2 a day. If it wasn't enough, they'd withhold their labour. Which works for academic economists: if they don't like Harvard they can move to Yale. For that kid in Indonesia, Nike may be the only gig in town . . . apart from prostitution or grubbing a living from a cassava garden.

                        There are four players in the Doughnut Economy: households [paid and unpaid]; the Market; the Commons; and Government. I've written about the Commons and how Garrett Hardin associated them - for all time- with tragedy. Some player would always try to put one more sheep on the common and the whole system would collapse dry up and blow away in a dust-storm. Not so fast, says Kate Raworth, for her the Commons are the glue of society all the things we do together without pausing to think if they are monetizable: busking, campaigning, Fortnite, peregrination, elder-care, after-school, adopting an unfluffy endangered species, starting a soup kitchen. We're on the planet for maybe 80 years, we'd better make the best of it. Reframing our existence from being a wage-slave to Capital to an equal contributing part of our community is a good place to start. contra Thatcher, the is such a thing as society: it's where I go drumming

                        Doggerland and other

                        When we lived in Boston in the 80s an occasional treat was to go to Friendly's and knock off a Very Berry Hot Fudge Sundae. We didn't stop doing it after we surprised to have a cockroach skitter across the counter-top as we waited for service . . . because that was our 'normal' at home. The management of the apartment complex never seemed to be able to get on top of the vermin.
