Bits and pieces

Several bits and pieces to talk about today. First, I was nominated in one of these “post seven lines from page seven of your current Work in Progress” challenges. It’s always a bit tricky picking out where page seven is, since I write initially for Kindle. But what follows is a fair guess. The story is (provisionally) called Timing. It opens with Mitnash and Slate back on the Scilly Isle asteroids, having just come in from a long and seemingly dull trip out to one of the moons of Jupiter. They are at Frag Rockers Bar with their friends, and one of them has just mentioned a leaflet which appeared recently, circulated by a group called Robin’s Rebels which Mitnash has never heard of.

Eibhlin took the leaflet from Rydal.

“Here, listen. ‘We are the voice of the downtrodden poor. Financial oppression is slavery; deals and investments are today’s whips and chains. But we speak for freedom and justice, and we have the technical talent to fight back. We will strike again and again at these parasites until the entire system is destroyed, root and branch. We will force out those who grow rich from others by means of clever financial tricks, and make them work at honest labour. You do not know us yet, but you will know us soon.’ Then there’s quite a bit more, all much the same.”

Finn was reading over her shoulder.

“Sounds like they’re up for a fight. Do you think they’re for real or just making noise?”

Robin’s Rebels feature prominently in Timing, along with several other old friends and adversaries – and new ones. As well as on the Scilly Isle asteroids, some of the action takes place on Mars and one of its moons, Phobos. All being well, you will find out more about all this towards the end of the summer…

As well as that, Far from the Spaceports has appeared in several reviews and interviews, which has been very gratifying. There has been something of an international flavour here. Sruti’s Book Blog, over in India, carried a review and two-part interview, which can be found at:

What was interesting about the book besides the awesome set up, and the background, was the author keeping in touch with the subtle ways of humans, way into the future.

Of course, there is fraud and there are people investigating it, but he manages to grab the reader’s interest, right at the start. How do the two of them manage to solve the mystery? How does it all work, in an environment that is so different from ours?

Then we move to Latvia, where Arnis Vēveris reviewed Far from the Spaceports on his blog. He kindly provides an English translation along with the Latvian. Among other things, he wrote:

“Wonderful atmosphere, great dynamics between characters and good mystery about the financial case”.

Then finally it was over to the US of A for an author interview with Don Massenzio, including an extract featuring the Frag Rockers Bar, my favourite hangout on the Scilly Isles. This starts with some easy questions like

DM: Can you summarise your book in one sentence?
RA: A human-AI partnership tackles hi-tech financial crime among the asteroids.

and then moves through several other questions to finish with the extract I mentioned.

Tales of Lindisfarne and St Cuthbert

Lindisfarne Castle
Lindisfarne Castle

I have just got back from a couple of days walking on and near to Lindisfarne – joined to the mainland at low tide, and an island at high tide. Lots of people drive there – it’s a short detour from the A1 as it heads up towards Berwick and Edinburgh – but there is something very satisfying about doing the journey on foot. Nowadays most people walk along the causeway which also carries the road, but the older pilgrims’ way branches off at an angle and heads more directly for the settlement and priory (now in ruins). The safe period at low tide is shorter here, and there are always a few places where you have to wade.

Across the Sands
Across the Sands

Lindisfarne has gone by several names. Holy Island is one, recognising a long history of sacredness. Christian monks and communities have thrived here since the 6th century, but one suspects that its liminal placing and seclusion marked it out for holiness long before then. The old Welsh name of Ynys Medcaut is thought to refer to the medicinal properties of herbs there.

Alongside the island’s sanctity, its location has meant that periods of conflict have washed across it. One of our first historical notes about the island records a time when an alliance of Briton tribes, led by Urien of Rheged (the North Lake District, basically), tried to capture Theodric of Bernicia (the northern half of Northumberland: the southern half was Deira). After an unsuccessful siege, they withdrew again. But with the rather later arrival of the Vikings, and several centuries of border trouble between England and Scotland, this part of the country became familiar with strife.

And that brings us to Cuthbert. He was born in 635 AD – the same year that St Aidan founded the monastery on Lindisfarne – and although details of his early life are scarce, it seems likely that he was born to a family of some rank. Be that as it may, on August 31st of the year that he was 17 – the very day that Aidan died – he had a vision and spiritual experience which led to him joining the monastery at Melrose. He moved around the north of England for the next decade or so – down to Ripon at one stage, for example – and got a reputation as a cheerful, self-denying, compassionate man with a capacity for imparting spiritual direction as well as bodily healing.

664AD was a significant date in British Christianity – the Synod of Whitby required conformity with certain European traditions, at the cost of local ones. Some of the older forms survived in what is now known as Celtic Christianity, but mainland Britain decided that church unity was worth preserving, and yielded to the demands. Cuthbert was caught up in this, and as some of the previous leadership at Lindisfarne went back to Ireland, he stepped in to a new role as prior – second in command. But after another ten years he took a different step and became a hermit, living a solitary life outside the rules of community.

Cuthbert's Island
Cuthbert’s Island

At first he lived in a small cell on an island adjoining Lindisfarne – attached at low tide, separate at high tide, just like Holy Island itself. But after a while he moved out to the more remote Farne islands, inhabited at the time only by seabirds and seals, as indeed it still is today. There are tales of his appreciation of the natural world, with seals coming and resting by his feet as he recited his way through the book of Psalms. Eider ducks are still called ‘cuddies’ to this day in commemoration of him. On good days, boats would set out from the nearby fishing villages to seek counsel, but on rough days, he was left in peace.

After another decade he was, reluctantly, called out of seclusion in order to take up the role of bishop. He tackled this with fervour, once again travelling widely around the north of England and southern Scotland, but feeling death approaching, he withdrew once again to the Farnes. He died there in 687, after a long illness.

Today a long-distance footpath called Cuthbert’s Way has been set up, and you can retrace his steps (more or less) from Melrose out to Holy Island.

Cuthberts Way

But his story was far from over. For many years he was England’s most celebrated saint, and pilgrims flocked to the sites linked with his activities. However, the times became unsettled, and Vikings started raiding monasteries up and down the coasts. The first raid on Lindisfarne was in 793, and the monastery was finally abandoned in 875. It was considered important to preserve Cuthbert’s body, so it was disinterred and carried from place to place, always keeping one step ahead of the looters – Chester-le-Street,Ripon, and so on. This went on for some time, until Cuthbert, presumably weary of his corpse being trailed about, called a halt. The coffin would not move from a spot in the bend of a river: the bearers, accepting the inevitable, built a cathedral there, and the town of Durham grew up around it.

It seemed that Cuthbert had found his final resting place… until the Reformation when the monastic tradition was under fire, and the stories that his body had never decayed were put to the test. Once again he was interred, and a rather confusing series of examinations by (royalist) doctors took place. In the middle of all this a body was declared perfectly ordinary, and reburied… but confusion remained. Had the body of another monk been substituted, to once again keep the sacred bones out of the hands of pillagers? If you believe that version, then the secret of the real location has been passed down within a select band of Benedictines (who had assimilated “St Cuthbert’s Folk” after the Norman Conquest), generation to generation. Perhaps one day he will come back to a restored and reunited church?

News from the asteroid belt

I thought it was about time for another space-themed blog today, so here are some interesting recent finds.

Ceres' Haulani Crater, from 240 miles up (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)
Ceres’ Haulani Crater, from 240 miles up (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

First, here is a high-resolution NASA picture of Haulani Crater on Ceres, taken from an orbital altitude of under 400 km.  The crater is about 21 miles in diameter, so would comfortably fit inside the M25 motorway around London. The level of detail is quite extraordinary, showing not only surface features such as landslides, but also allowing some inferences about the relative age of the different portions.

The scattering of bright spots on the surface of the asteroid has excited a great deal of conversation since they were first identified as Dawn drew closer on its long journey. Even with the close-up views, uncertainty remains, and probably will do until such point as something can actually land there. Meanwhile, the best guess is that they reveal traces of chemical deposits, probably some kind of salt. When you read of the asteroidal settlements called the Scilly Isles in Far from the Spaceports, imagine scenes like this out on the surface…

Atmosphere! When you read old science books, or old science fiction, most moons and similar small objects were believed to be completely airless bodies. Atmospheres were thought to be the province of “real” planets. But the more we have been able to get a close view, the more we realise that atmospheres are the rule rather than the exception. This image shows the view of Pluto captured by the New Horizons probe as it receded further away from the sun – the atmospheric haze extends out to about 80 km, considerably further than anybody had expected.

These atmospheres are generated by a whole mix of local conditions. These include the effects of the distant sun’s warmth driving chemical reactions, nearby bodies flexing the surface slightly, and so squeezing gas out of the rocks, as well as internal chemical or seismological actions. Now, it’s as well to remember the vast majority of the gases found are not only toxic, but also far too thin to be of much use… nevertheless finding them at all has been a surprise.

Finally, Mars. A good chunk of my forthcoming book (which currently has working title Timing) is set on Mars and one of its moons, so naturally I have been following discoveries there with interest. Now, our present selection of gadgets on Mars, while extremely clever and carrying out their missions in exemplary manner, come a long way short of what I have in my fictional imagination. Mars in the new novel has a wide variety of different communities, from a financial training college out near the giant mountain Olympus Mons, through to an anarchic and hedonistic settlement at Elysium Planitia. We are some way from achieving those yet, but there’s plenty of time…

That’s it for today. There seems to be plenty to discover out in the solar system. Some of the findings reinforce what was previously believed, but others open up whole new and unexpected areas. Happy reading – both fact and fiction.

The Kirkstone Pass

Map - the Kirkstone Pass
Map – the Kirkstone Pass

In all my years of visiting the Lake District, I had never before been through the Kirkstone Pass. It sits between the lakes of Ullswater and Windermere, and is fairly remote from the northern and central areas I normally go to. But with the A591 road from Keswick to Grasmere still closed from the winter storms, this remote route is the quickest way to make the journey down to Ambleside.

Wordsworth, inevitably perhaps, wrote about the pass:

Within the mind strong fancies work,
A deep delight the bosom thrills,
Oft as I pass along the fork
Of these fraternal hills:
Where, save the rugged road, we find 
No appanage of human kind,
Nor hint of man;…

Who comes not hither ne’er shall know
How beautiful the world below;
Nor can he guess how lightly leaps 
The brook adown the rocky steeps.

The hills above the pass
The hills above the pass

His main concern was the feeling of absolute removal from the built things of mankind, and the way purely natural objects came to attain a significance beyond the normal. The pass gets its name from a large rock that has the shape of a church – a kirk. Along with that, he pondered, as perhaps most people do after reaching the summit of the pass, on the generations that had done the same journey: 

When through this height’s inverted arch
Rome’s earliest legion passed!

Now, on a purely objective scale, the Kirkstone Pass is the highest in Cumbria – nearly 1500′ – and it certainly feels that way. As well as a few hundred feet advantage over, say, the Honister Pass, the approach from Patterdale is so long and bleak that the sense of relief on getting to the top is very pronounced!

Now, on the day I was there, the most extraordinary sight awaited, with the Windermere valley stretching ahead to the south completely full of cloud. The way up had been under clear skies, and the mist was dissolving minute by minute. Already the side-road down – The Struggle – is becoming visible.

The Kirkstone Pass Inn
The Kirkstone Pass Inn

The Kirkstone Pass Inn has a sign suggesting to travellers that it has been in action since the 15th century. This is something of artistic licence, since for many of the intervening years the place seems to have lain in ruins. But – so far as one can tell – there has been a building on this spot serving drink to weary passers-by for many of those years. Every now and again, the sheer difficulty of getting there, and the bleakness of the existence in long cold winters, forced the occupants back down to the valleys. It is, after all, the highest inhabited house in Cumbria. But if you can handle the emptiness, it is a great place for a pub! On occasion, it has also served as a retreat for monks, presumably of an order that wanted to retreat from worldly distractions.

I also learned that this Inn is considered one of the most haunted places in England. Many of the apparitions are those of people who died tragically on the road – typically within sight of the homely walls but unable to reach them. These are – by repute, at least – benevolent towards the living. But other ghosts have a more sinister reputation, and tales are told of groups cancelling reservations after a first, sleepless night. I didn’t test out the ghost stories, but instead turned down the road to Ambleside, thinking to myself that there have to be some good stories that tap into the history of this place.

Phobos and Deimos – history and speculation

Today’s blog bridges past and future, and focuses on Phobos and Deimos – the two moons of the planet Mars, named after the two chariot horses of the Greek god of war (Ares, for whom Mars is the Roman equivalent).

Phobos (NASA)
Phobos (NASA)

These moons were discovered by the American astronomer Asaph Hall at the Naval Observatory at Washington DC in 1877. He had been searching for them for some time, and was at the point of giving up when his wife Angelina encouraged him to persist. The following night, in a serendipitous moment even better than fiction, he was able to identify Deimos, and six days later he spotted Phobos as well.

Map of Laputa and Balnibarbi (Wiki)

But this tale goes back about 150 years before that, to 1726 and the satirist Jonathan Swift. In the third part of Gulliver’s Travels, having visited the better known lands of the miniature and gigantic – Lilliput and Brobdingnag – Gulliver arrives at a realm of scientists, called Laputa, floating in mid-air. The inhabitants are brilliant, but also implacably ignorant of worldly matters, and as a result, their ideas are usually impractical. Theirs is an interesting story, but the key paragraph from today’s perspective is in the third chapter, and reads as follows:

They have likewise discovered two lesser stars, or satellites, which revolve about Mars; whereof the innermost is distant from the centre of the primary planet exactly three of his diameters, and the outermost, five; the former revolves in the space of ten hours, and the latter in twenty-one and a half

The corresponding figures agreed by astronomers today are 1.38 and 3.46 diameters rather than 3 and 5, and 7.7 and 30.3 hours rather than 10 and 21.5. So his values are remarkably close to those agreed today, yet he had no apparent way to know them. This curiosity has excited a lot of energetic speculation, and no little conspiracy-minded thinking.

It seems likely – taking a more sober view – that he was basing his ideas on patterns of numbers. Mercury and Venus have no moon, Earth has one, and at the time Jupiter was known to have four. Five moons had been spotted around Saturn, and it would be a reasonable guess that another three would be found to give a total of eight. What more natural suggestion than that Mars had two? Kepler had made a similar suggestion, back in 1610.

Swift’s figures for the orbital size seem to be copied from values for Jupiter’s innermost moons Io and Europa, and the orbital period is then derived on the assumption that Mars has the same mass as the Earth. So his speculations may in fact be perfectly logically deduced, given the limited information at his disposal.

But the oddity about these moons did not stop with Swift. Nearly 15 years before Asaph Hall, a team led by H L d’Arrest at Copenhagen, working under more ideal viewing conditions, had failed to detect them. Not only that, but both moons are extremely light for their size, and the orbit of Phobos is close enough to Mars that it will not survive long in planetary terms – it is steadily decaying towards the fringes of the atmosphere. Finally, the surface of both moons is unusually dark – they are among the least reflective bodies in the solar system.

“That’s no moon” (Wiki)

So the idea spread in the late 1950s that they were not natural moons at all, but artificial satellites put into orbit by a hypothetical Martian civilisation sometime between d’Arrest and Hall. This particular idea persisted right through to the presence of our own spacecraft orbiting and landing on Mars. I dare say that some people still adhere to it – after all, you can quite easily believe that an advanced race might disguise an artificial satellite as a moon.

But there are genuine unknowns still about these moons. Nobody has yet come up with a totally convincing theory of their origin – did they cool from the original disc of solar system matter at the same time as Mars itself? Are they splinters from Mars resulting from a prior collision with a suitably large body? Or were they captured from the relatively nearby asteroid belt?

Their low density has also attracted interest. Are they only very loosely packed collections of rubble-like material, rather than solid rock? Or perhaps there are significant cave-like voids riddled through the volume?

Until such time as we establish some kind of real presence on Phobos and Deimos, thus starting the real history of those moons, some of these ideas will remain purely conjecture…

Grasmere, Thirlmere, and Dunmail, last king of the Britons?

Dunmail Raise, between Grasmere and Thirlmere (Wiki)
Dunmail Raise, between Grasmere and Thirlmere (Wiki)

North of Grasmere and south of Thirlmere, beside today’s A591, there is a large cairn of stones, known as Dunmail Raise – the name also applied to the watershed between those two lakes. It turns out that there is a considerable collection of history and storytelling around this cairn, and I thought today I’d relate a little of that.

Cumbrian flag (http://www.englishcountyflags.com/)
Cumbrian flag (http://www.englishcountyflags.com/)

It seems broadly agreed that Dunmail (probably the same as Dyfnwal ap Owain, to give him his Cumbrian name) was a king who was defeated by the Saxon king Edmund, who had allied himself with the Scottish king Malcolm. The Anglo-Saxon Chronicle commentsA.D. 945. This year King Edmund overran all Cumberland; and let it all to Malcolm king of the Scots, on the condition that he became his ally, both by sea and land“. This was just one among the endless shifts of allegiance along the borders – a generation earlier, Malcolm’s father Constantine had joined with Owain against Saxon king Athelstan. They lost that battle – Brunanburh, 937AD – and Owain himself was reputedly buried at Penrith.

Grizedale Tarn from Dollywaggon
Grizedale Tarn from Dollywaggon

In the repeated telling of this basic tale, Dunmail attained almost Arthurian status. In one version, his sons were blinded by the victorious Edmund. In another, his loyal followers took his crown – to ensure that the Saxons would not claim it and the kingship – and nipped up the track to Grizedale Tarn (following today’s Coast to Coast trail) and cast the crown into the depths. When the time was right, he and it would be reunited and the ancient kingdom restored.

Another interesting source of variation is in the meaning of the cairn itself. One version simply holds that it was a boundary marker between the old regions of Cumberland and Westmoreland. Another reckons that it marks the burial place of Dunmail himself. But the version I find most appealing is that it recalls an old military tradition, in which soldiers going into battle would pile up “soul stones” as a safeguard. If they survived, they retrieved the stone from the pile… if not, well the number of stones in the pile was the number of casualties.

Observed in the light of archaeology and historical research, there are a great many uncertainties. Did Dunmail actually die as stated? (There is a separate tradition that he died later while on pilgrimage to Rome). What nationality was he? (Contenders include Norse or Celtic as well as Briton). But to elevate his romantic and literary status, I am going for the idea that he was the last king of the British… as William Wordsworth expressed it in The Waggoner,

The horses cautiously pursue
Their way, without mishap or fault;
And now have reached that pile of stones,
Heaped over brave King Dunmail’s bones;
His who had once supreme command,
Last king of rocky Cumberland;
His bones, and those of all his Power
Slain here in a disastrous hour!

 

Making companionship

Pygmalion and Galatea, by Falconet (Wiki)
Pygmalion and Galatea, by Falconet (Wiki)

Last time I looked at our changing views of the animal world, and our ongoing attempts to find companionship there. But alongside that there has always been the recognition that animal or bird companions don’t quite satisfy. The Hebrew Bible sums it all up with the comment that none of the creatures was ideal as a partner, and moves on to the need for a second human. Whatever you make of the details of that account, the remaining pages of the Bible go on to describe all manner of human relationships – as well as opposite sex and same sex pairs, we find family and strangers, leaders and followers, friends and enemies, pairings which were suitable and entirely unsuitable. The other sacred texts of mankind are the same in this respect – alongside communications with the divine, human interactions are everywhere.

But for some reason, as a species many of us have been perennially disappointed and frustrated with relationships with one other – a sorry trend for which one can very easily find counter-examples, but which has fuelled many of history’s conflicts, both national and personal. Perhaps the autonomy and potential for disagreement in another individual is too disconcerting. Whatever the cause, the idea of building some sort of mechanical person goes back into the ancient world.

Greek myth has several variations on this theme, including Pygmalion’s ivory statue which animated to become his wife, and Hephaestus’ automata who assisted at his forge. In these cases, divine intervention of some sort was necessary to make the transition from dead to living. But in addition, Daedalus is said to have used quicksilver in order to impart speech to his statues, so the possibility of a human invention was considered.

For many centuries, speculation about artificial life circled around biology rather than metallurgy. Medieval alchemists toyed with the idea of homunculi, miniature humanoids whose creation required a series of esoteric steps such as leaving human sperm to incubate in horse manure for 40 days. Suggestions that the true quest of the alchemists was spiritual rather than physical make a lot of sense. The discovery in the late 18th century that human nerves responded to electricity triggered new ideas, which in literature were summed up by Mary Shelley in the person of Frankenstein and his research, leading to the creation of his life-form.

Today, the pursuit of artificial intelligence is largely seen as a technological challenge. By and large, we are working on the assumption that the main breakthroughs need to be in software, and that the container which houses the resulting application is only a convenient package allowing access to various kinds of sensory input. Time will tell if this assumption is valid.

We have a mixed attitude to artificial life. On the one hand we welcome it as a possible assistant and helper, but on the other we are anxious about possible failures of control. Will the creation refuse to obey the creator? Will it have end-goals which are hostile to our own well-being? In fiction, and to a degree in actuality, we try to govern this by logic. Isaac Asimov postulated that all robots had to obey three laws intended to protect humanity, and simply asserted that it was not possible to construct an artificial brain without these constraints. Frankenstein, on the other hand, rapidly lost control of his creation, largely through not understanding and empathising with its needs.

In the near-future world of Far from the Spaceports, some of these particular problems have been solved. Slate and her persona siblings are, on many levels, fit companions for Mitnash and the other humans they partner. But not in every way. Mitnash enjoys Slate’s company and her capacity for work, but often finds himself challenged by the ways in which she differs from his expectation. He often does a poor job of maintaining good relationships with both Slate as his working partner, and Shayna as his romantic one. Quite apart from the everyday difficulties of balancing work and life, Mit has to constantly choose how to relate to two quite different female partners. Our society struggles to balance the competing demands of an online world and our immediate family and friends – I have every expectation that this future society will struggle as well.

To finish, just for fun, here is a NASA picture showing the gravity variation on Mars. It has no connection with this blog post, but some of the action of By Default takes place on that planet!

Looking for companionship

Early Christian depiction of Adam and eve (Wiki)
Early Christian depiction of Adam and eve (Wiki)

Our quest for companionship goes back a long way. According to the Hebrew Bible, it arose during the time of creation, when God brought all the animals and birds to the man – “the human” would be an appropriate translation. The reason was “it is not good for the human to be alone” Then “the human proclaimed names for all the domesticated animals and for the birds of the skies and for all the living things of the open country“. Sadly, amongst all of this array of life, no suitable helper could be found. So God went on to make a suitable helper.

My point today is nothing to do with how best to understand the creation story in Genesis, but to show that this tradition – along with many others all around the world – presents the idea that mankind has wanted to find companionship of some kind with the natural world for a very long time. We use the natural world all the time in our descriptions, similes, and metaphors about human behaviour, and although there are some mismatches when we try to carry such metaphors cross-culturally, by and large they survive translation very well.

The Biblical tradition became, through the course of time, increasingly antipathetic to representing the godhead in terms of animals, but animal metaphors remain strong throughout – eagle, bull, lamb, and so on. In other traditions, where the constraints against idolatry were weaker or absent, living things have been fair game to stand in for gods, demigods, spirit guides, familiar spirits, and so on. The Egyptian tendency to associate animal features with otherwise humanoid deities intrigued (and rather horrified) Europeans. But the Egyptians are very far from the only culture to do this. Classical Greek literature is full of transformations into and from animals, birds, plants, and so on. Hindu sacred texts associate one or more vahanas with each deity. These were – are – devoted companions, often used for riding, and typically taking animal or bird form – bull, elephant, peacock, mouse, tiger, owl, and so on.

Personally I’m not so bothered about a literal interpretation of all this, but I am very interested in what it might carry in terms of meaning. There’s an obvious connection in terms of linking the qualities of the beast with the god in question. So Sekhmet – with her lion head – was thought to protect the line of pharaohs and lead them in battle. But on another level, followers are encouraged to meditate on the imagery, and to use the real-world object as a vehicle to approach the godhead. Modern neuroscience thinks in terms of an animal brain, and a reptilian brain, and so on, biologically nestled within our human brain, and tending to pop to the surface and dominate our reactions from time to time.

Advert for the Learned Pig, early 19th century (PInterest)
Advert for the Learned Pig, early 19th century (PInterest)

Another modern symptom of the same trend is the quest for animal intelligence. We have found signs of this in dogs, pigs, most of the apes and upper primates, corvids, parrots, dolphins and whales, and so on. The early 19th century saw great interest in Learned or Sapient pigs, able to accomplish a wide variety of tasks… or where they just tricks? Since then we have expanded the study to a whole bevy of other living things, and in the process come to realise that we don’t really understand human intelligence! Which part of the brain is responsible for it? Or is it a generalised response emerging somehow out of the whole organism?

So we are still looking for companionship here on Earth, whether spiritual or intellectual. Arguably the quest for discovering alien life out in the rest of the cosmos is part of this great search. If it really is “not good for the human to be alone” then the quest will no doubt continue for a long time to come… in parallel with the quest to find companionship in the humans alongside us.

How far away is Artificial Intelligence?

Over the next few days, Google’s Go-playing algorithm, AlphaGo, will take on the current world Go champion, Lee Se-dol. It is an event which is being watched closely by both Go players and coders, since until very recently Go was thought to be a game intractable for machines to play competently.

I’ve worked in various ways with AI over a lot of years now, so thought it was high time I wrote about it here. Far from the Spaceports, and the in-progress follow-up By Default, have human-AI relationships at their heart. Mitnash, a thoroughly human investigator and coder, has Slate as his partner. Slate is an AI – or persona, as I prefer to use in the books – and the two work together in their struggle against high-tech crime.

How far are we away from this? In my opinion, quite a long way. There have been huge advances in AI during my working life. This has largely been made possible by corresponding advances in the speed and capability of the hardware systems on which they run. However, creative ideas for how to code learning algorithms and pattern recognition have also come taken huge strides. Nevertheless, I don’t think we are very close to working with Slate or her fellow personas just yet.

Of course, you have to be mindful of a quote attributed to Bill Gates: “We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten.” But that said, I still think we’re some way off.

There are a lot of different, and very useful, ideas as to what constitutes intelligence, but for the purpose of this blog I am largely focusing on the abilities to learn and then detect meaningful patterns, work usefully with inconsistent or poor quality information, and communicate about all this with another individual in such a way that both parties can revise their opinions.

Part of the problem is that most people are working on a very small part of the problem, and the organisation paying them only really wants quite a specific outcome. So one team might be working on machine health monitoring and fault prediction, to improve aviation safety. Another will concentrate on whatever is needed to identify objects in photographs. Another on voice recognition. Another on being able to beat human champions at a specific game. And so on. Comparatively few are integrating all this into a single entity.

Human intelligence is also noteworthy for being able to adapt flexibly to new situations, calling for similar but not identical responses. So my guess is that Lee Se-dol probably also plays an outstanding game of chess, or Senet, or any of dozens of board games. At a guess, he could probably hold his own very well at some game he had never seen before, after a comparatively brief explanation of the rules. I have serious doubts as to whether Google’s codebase could make such a transition.

Another issue is repetition and predictability. If you’re coding a safety system, you really want to know that the same set of circumstances will lead to the same consequences. Quite apart from giving confidence to your immediate users, there is the whole matter of getting the system qualified for use. Imagine your system has failed to recommend replacement of a critical component. There has been a crash, and you are at the investigation. “Why did your system fail to recommend that the component be changed?” And you reply, “Oh, I don’t know – it says something different every time.” I can’t imagine this going down very well with the investigation committee. For the reaction of a friend, however, unpredictability is part of the fun.

We find it difficult to define what intelligence really is, or which part of our being is responsible for it. Recent comparative studies in which bird and primate intelligence are contrasted, have questioned the idea that it is seated in the cortex: birds don’t have such a thing. In the light of such basic uncertainty, corporate reluctance is understandable. It is hugely easier – and hugely more cost effective – for an organisation to say “build me a system which can identify patterns of word use by different authors” than “build me intelligent partners for my human staff.”

As someone working in a tech industry, I am keenly aware of, and excited by, the possibility of AI. How would my team carry out quality assurance for such a system? It’s often hard enough to do this for a complex but entirely rule-bound application. The challenges are immense.

But as an author, I am entirely free to suppose that all that has been done, and focus on the storytelling issues of how such a relationship would work.

Reviews and a guest blog

Not much new here this week, since my blogging effort has mainly gone into a guest blog at Antoine Vanner’s Dawlish Chronicles, on the subject Prehistoric Seafaring along the Atlantic Coasts. Normally Antoine’s blog deals with 19th century naval issues, but on this occasion he was kind enough to let me take his readers back into the Bronze and Neolithic ages.

On to reviews. The Flame Before Us has just had a very pleasant 5* review on Hoover Book Reviews. “From the noble, nose in the air, Egyptians to the settlements of peasants to the nomadic clans, we have a tale of loss, hardship, and hope as cultures collide and times change.  Kudos to the author for a most enjoyable series.  I look forward to more.” And in time, hopefully there will be more.

And finally, for those who haven’t yet seen it, here is a review of Far from the Spaceports. This review is by Ian Grainger, who regularly produces my covers. Science fiction is much more his cup of tea than historicals…
