The Planets

Andrew Cohen with Brian Cox
The Planets (5*)

This is a book packed with incredible, fascinating detail which Mrs. D. has thoroughly enjoyed being told about, especially when watching television, reading a book of her own or settling down to go to sleep.

My knowledge of the solar system had changed little since the nineteen-sixties. It was based on the moon landings, a 1957 set of Brooke Bond tea cards, the nineteen-sixties encyclopaedia Knowledge which came out in weekly parts, and my dad’s Arthur Mee’s Children’s Encyclopedia from the nineteen-twenties. These two tea cards just about sum it up.

I mentioned this at home, and for my birthday there appeared a brand new copy of The Planets by Andrew Cohen with Brian Cox, published in 2019 to accompany the television series of the same name. Professor Cox presented the series: it gave him an excuse to pose in all sorts of weird and wonderful locations, such as the Wadi Rum in Jordan, and pretend he was on the surface of other worlds. He is credited with just one of the six sections of the book. The others are by Andrew Cohen, the executive producer of the series.

It is very readable and accessible. Perhaps only once or twice did I feel bogged down in too much information, but that may have been because I was rushing to get to the next astonishing section. Let me pick just a few of the snippets Mrs. D. so much appreciated hearing about, to try on your loved ones in deciding whether or not to get the book yourself.  

Olympus Mons

1) There are some extraordinary mountains elsewhere in the Solar System. Olympus Mons on Mars, a volcano of 21,000 metres, is around two and a half times the height of Mount Everest. It looks a bit like, well, yes, it does.

2) Staying on Mars, the Curiosity landing vehicle has provided us with many high quality images of the surface. It was so heavy (998kg or around a ton) that to have dropped it on to the surface in the usual way could have damaged it beyond repair. It was therefore lowered gently at a rate of one metre per second from a “sky crane” hovering twenty metres above the surface. The sky crane then flew off so as not to fall on the landing vehicle. How on earth did they think of that, and how did they get it to work?


3) The planetary orbits have not always been as they are now. It is thought that as the Solar System was forming, four and a half billion years ago, Jupiter moved closer to the sun and then back out again (known as the grand tack hypothesis), taking with it thousands upon thousands of blocks of rocks and ice to form the asteroid belt. This reduced the amount of material available for the inner planets to form, which is why Mercury, Venus, Earth and Mars are much smaller than Jupiter, Saturn, Uranus and Neptune.

4) The time-scales are unimaginable. Over the next five billion years, the Sun will grow hotter and expand to engulf Mercury and Venus, although the lifeless, burnt-out Earth may just escape this fate. At the same time, the outer planets will begin to warm. Worlds such as Titan, a moon of Saturn where lakes and rivers of methane run through mountains of ice, will thaw to have oceans of liquid water full of complex organic chemicals, just the kind of place where life might originate all over again.  


5) Pluto, which was only discovered in 1930 and appears in the Brooke Bond tea cards as the ninth planet, is no longer classified as a planet …

[note: at this point Mrs. D. snatched the book from Tasker’s grasp and beat him about the head with it].

Penelope Lively: Moon Tiger

Penelope Lively

Moon Tiger (5***)

Yet another Booker Prize winner not read at the time: from 1987 in this case, sought out after reading Treasures of Time and A House Unlocked which we inherited from my mother-in-law. Moon Tiger is highly regarded, and rightly so. I was not disappointed.

It begins with an elderly woman dying in a hospital bed. Not the most appealing topic I can think of, and not a particularly likeable woman. She had once been a highly intelligent, attractive and successful popular historian who looked down on those not so gifted, such as her sister-in-law and even her own daughter. Yet, without much perseverance, you are drawn in and begin to warm to the character.

As she lies there, mind wandering, she begins to write a history of the world, no “nit-picking  stuff” but “… the whole triumphant murderous unstoppable chute – from the mud to the stars”. It is really her own history: the lifelong competition with her brother, her relationships with her daughter, the father of her daughter and the lover she found and lost as a war correspondent in Cairo, and the phases of her life before, during and after.

All are present in her thoughts at the same time. Episodes from different periods come out of sequence, told from different points of view – hers, her brother’s, her daughter’s – sometimes in the first person and sometimes in the third. The analogy is the moon tiger, “… a green coil that slowly burns all night, repelling mosquitoes, dropping away into lengths of grey ash, its glowing red eye a companion of the hot insect-rasping darkness.” Like memory, it becomes a messy spiral of ash in the saucer. 

As in her other books, Lively is re-working her recurring themes and concerns: the interpretation and reinterpretation of memory, how different people’s memories of the same events can differ, how the past relates to the present, and personal history. It results in a complex structure despite which the narrative moves adroitly forward, a considerable feat for an author to pull off, perhaps even more accomplished than A. S. Byatt’s Possession, the 1990 winner which I also admire.  

It reminds me of T. S. Eliot:
Time present and time past
Are both perhaps present in time future,
And time future contained in time past.
If all time is eternally present
All time is unredeemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.

Fort William

Ben Nevis from Corpach
Ben Nevis across Loch Linnhe from Corpach

I was a bit apprehensive when Mrs. D. and I set off for Fort William last week. It is thirty years since I was last there and when your age begins to begin with a seven you wonder what you can no longer do. Was I still up to walking in the Scottish Highlands? Did I have the stamina? Would my legs and back last out? How would I cope with the long drive? 

I used to go there a lot. The first time was in 1964 with my parents when I took this shaky photograph of the Ballachulish ferry with my Brownie Starmite camera. The ferry avoided a nineteen-mile detour round by Kinlochleven which could take over an hour in holiday traffic. It was replaced by a road bridge in 1975, but the old ramps are still serviceable as the modern picture shows.

I went again on camping and walking trips with friends in the seventies and eighties. We pitched our tents countless times at Glencoe and Fort William, and passed through on our way to Skye. 

We always walked the big stuff. We climbed Ben Nevis straight up the four thousand feet from Glen Nevis: up the steep grassy slope into the Coire Eoghainn corrie where we heard a cuckoo, then up the boulders of the right shoulder and on through the snow to the top. Much more fun than the relentless ‘pony trek’.

We back-packed and wild-camped our way across Rannoch Moor which, unlike now, was practically empty of any other walkers. We traversed the ridge of Aonach Eagach in Glencoe, the scariest walk I have ever done, stupidly going around some of the pinnacles instead of scrambling over them. Even scarier than the Cuillin ridges above Glen Brittle in Skye.

We tried nothing like that this time, not that we would have done anyway, but poor visibility and a wind-chill equivalent of -7°C (19°F) on the peaks around Ben Nevis gave a good excuse. We could see the mountains in the murk but rarely the tops. However, there are lots of low-level walks around Fort William I would never have considered in earlier years. 

There is a stunning walk of around four miles there and back from the end of Glen Nevis to the Steall waterfall. When I trekked the 13 miles from Corrour in the opposite direction in the nineteen-eighties there was hardly anyone around, but on this day there were lots, some coaxing five year-old children over the steep and rocky terrain, everyone soaked, but everyone with smiles on their faces.

For more solitude we went to Loch Arkaig to the west of Loch Lochy in the Great Glen. The track along the north shore is one of the routes to the remote and sparsely populated Knoydart peninsula, reachable only by boat along the coast or a sixteen-mile hike across rough country. The story of how the population was cleared by the landowner in the eighteen-fifties and left to survive out in the open is cruel beyond belief. We walked a couple of miles along a forestry road on the south shore before retracing our steps thoroughly soaked. Even my underpants were wet. Trying to survive out in the open in weather like that does not bear thinking about, even with the protection of modern outdoor clothing.

Yet another day saw us in Glen Roy. What an incredible place that is. Twelve thousand years ago it was a glacial lake, marked out by three successive shore lines (the “parallel roads”) along the sides of the valley – the lowest is the oldest and the highest the most recent. Analysis of the sedimental layers show that the lake system existed for 515 years, and when the ice-dam finally burst it released five cubic kilometres of water in a spectacular “jökulhlaup” that carved out the River Spean gorge. The entire glen is full of glacial features.

Despite sunny periods to begin with in Glen Roy, the weather soon turned for the worse, and again we had to retreat. In fact, we got soaked every day. We originally booked the cottage for early June but rearranged it for the end of October because of lockdown. For the whole week we got out promptly each morning, returned to the cottage to dry out and have something to eat, and then went either for a touristy drive to somewhere like Oban or Glenfinnan, or did our local walk. 
The cottage was at Banavie at the end of the Caledonian Canal between the sea lock which opens into the sea loch at Corpach and the flight of eight locks known as Neptune’s Staircase, which made a handy three-mile circular walk, usefully past a bottle bank. All in all, we had a good week despite the wetness, with so many bursts of intense happiness I thought I was beginning to turn into Gerard Manley Hopkins. And yes, given drier weather, I might still be up to something a bit more challenging. Not Ben Nevis, though.

Lastly, for any bovine photographers out there, this is what you have to cope with on some of the quieter roads. Remember to fold your mirrors in.

New Month Old Post: Hi there Duggy!

A student sends an awkward email to an eminent professor

Early in the nineteen-nineties, I came across a strikingly enlightening piece of research that suggested that girls who learn things together, remember much more than boys. It was an experiment in which pairs of eight-year-old children explored an interactive videodisk – the kind of thing that tells an illustrated story in which, if you click on a word or group of words, it reads it out, and if you click on an object or character in a scene then something happens, for example clicking a parked car in a street scene sets off the alarm, or clicking a tray of biscuits in a kitchen makes them sing. It was a new and unusual experience at the time. 

Some weeks later the children were asked to write essays about it on their own. The surprising result was that girls who had been paired with other girls remembered twice as much as boys or girls who had been paired in other combinations.* There were other aspects to the experiment too, making a useful contribution to the idea that educational software can encourage learning through collaboration as well as individually.

I stumbled upon this as a new lecturer in a recently upgraded northern ex-polytechnic, hoping to carve a niche for myself by devising innovative courses about emerging technologies. I asked students each to lead a small, short seminar about a published research paper from a list. One student, let us call him Arshad, chose the paper about the pairs of children and the videodisk. 

Email was relatively new in those days. Some university staff still resisted its use, and those who welcomed it were having to come to terms with the accessibility and informality it brings. We took pains to educate students about the possible pitfalls. It seemed inevitable that things would sometimes go wrong, but it was with disbelief that I read the email Arshad had sent to the author of the research paper.

The author was Professor Dougman Fairwood, an eminent and influential Head of Department in a top Russell-group university, author of numerous books, review articles and research papers across a wide range of topics. He had been awarded many high-value research grants, guided no end of doctoral students to successful completion, served on government advisory committees and was internationally respected in his field. You get the idea. Think of those over-achieving grey academics who only creep into the public eye when they advise or criticise governments in times of crisis. Most are pathological workaholics and take themselves very seriously. They get upset if you don’t address them formally, or fail to treat them with the respect and deference they think they deserve. 

This is the email Arshad sent:


Subject: Study questions?
Hi there
Hows it going,, My name is Arshad A-----, Im a student at --- University, Currently I am reviewing one of your publications titled “------------ ---- ----- ----------”. Its realy cool and I would be very gratefull if you or you coauthor Mrs Farwood would be so kind to answer a few questions reagding the study.
1 - Was there any initial asumptons taken into account about the children taking part in the study? (if any, how valid were the asumptons?).
2 - Taking a retrospective look at the study, how well do you think the study was carried out?, do you think anything was overlooked in terms of implemantaion or methodolgy?
3 - Do you think your study has any implicatons or links to other ideas?
4 - How importantly do you think your study is relevent today and more importantly in the future?
Thanks in advance
Keep it up
Arshad A-----.
It was not long before an angry reply was circulated to staff.
Dear Colleagues

The attached is a message received both here and by my co-author, and comes, apparently, from a --- University student. The student does not identify his Department, so I’m sending this complaint to the Heads of Psychology, Education, Computer Science, Engineering, Multimedia and Information Systems, with a copy to the Vice Chancellor.

Your student appears to be writing an assignment on one of our papers, and the questions that we are being asked are just the kinds of questions that a tutor might set. Is it your practice to have your students get the answers to their questions by doing the equivalent of looking at the back of the book? Obviously not, and you might want to take some action to inform the student about your preferred practice.

But the main reason for writing is to complain about the e-mail itself. The interrogational style had ------ and I phoning each other to ask what was going on here. Speaking for myself, I am decidedly cheesed off with this e-mail. Being asked to justify the validity of my own assumptions, or the relevance of my work, is something that I do not expect from a student hoping to pass a term paper. Of course, if you believe that your student is doing exactly the right thing here, then I would be especially grateful to hear from you.

Best regards

Dougman Fairwood.

Professor Dougman P. Fairwood BSc PhD DSc CPsychol FBPsS

I can think of at least five so-called rules of email etiquette Arshad ignored, but even had all been followed correctly, the content was way out of order. Students may well have genuine grounds for writing to staff at other universities, but they should always pass it by their own supervisors first. They certainly should not do it in such a clumsy and tactless way.

I drafted a grovelling apology but never had to send it. It turned out that our Head of Department had already apologised on behalf of the university believing that Arshad had been reading around for his final-year project. No one ever associated his email message with the course I was teaching. That was fortunate because at the very next academic conference I attended, I got into conversation with the friendly chap sitting next to me and asked his name. “I’m Doug Fairwood,” he answered and invited me along for a coffee. We had an interesting chat about interactive videodisks.

I raised the matter of the email with Arshad but he paid little attention, and when his seminar came along it was fairly obvious he had not really read or understood the research paper at all. He still graduated that year with a respectable degree – well, he was a nice enough lad and the university did not like us to fail people. I wonder what he’s doing now.

* One possible reason for the girls’ so much stronger recall is rehearsal, i.e. the more you repeat something the better you will remember it. Girls, being more sociable, seem more likely to have talked about their experiences afterwards between themselves, possibly in play. Strangely, the authors did not consider this in their paper. Professor Fairwood seemed very interested when I suggested it to him.

The Song Book

If by chance I loose this book 
If by chance you find it 
Remember Kathleen is my name 
And Clayton comes behind it. 
The News Chronicle Song Book 1931
Around 1960, my father came home with a copy of The News Chronicle Song Book given to him by an acquaintance who lived in the East Riding village of Asselby. It was in a terrible state, but he stuck it back together and fitted a brown paper jacket on which he wrote: “This book was paper backed and repaired on a wet Thursday afternoon February 25th 1960 by [him, me and my brother]”. A father on his half-day off keeping his two children occupied during school half-term.
The introduction suggests:
Singing together is a form of amusement and delight. It is a glorious way in which we can, in large bodies, express something which we could not tell in any other way. But the love for Community Singing should be started and finished in the home. … With this Song Book the “News-Chronicle” hopes to encourage and bring back singing in our home. The Community Singing will take care of itself.
I wholeheartedly agree but have never been much of a community singer. Despite a good sense of pitch, I find it difficult to hear my own voice in groups. At home, though, yes. What fun it gave us. No one played an instrument, we just turned the pages and sang. 
The cover gives an idea of what it contains. Looking again now turns up some great favourites: 
  • Dashing Away With a Smoothing Iron 
  • Come Lasses and Lads 
  • Billy Boy 
  • David of the White Rock 
  • Ye Banks and Braes
  • Marching Through Georgia 
  • Camptown Races 
  • Go Down Moses 
  • A Roving 
  • Eternal Father 
  • O Come, All Ye Faithful 

Wow! How long a list can get I away with? All two hundred? I feel a sing-song coming on. 

‘Twas on a Monday morning … me Nancy kittl’d me fancy … doo-dah doo-dah … to trip it up and down … tell old Pharoah to … bring me the harp I adore … I’ll go no more a roving … in peril on the sea. 

                                                *                          *                          *
We have a tape recording from 1963 of one of my dad’s unselfconscious performances. His granddad had been a sea captain which, he said, conferred upon him an inherited natural aptitude in the delivery and interpretation of sea shanties. 
“And now from my sea shanty series,” he announces, his tongue in a twist, “the old song book page one hundred and twenty four: Bound for the Rio Grande.”
Two children mutter and snigger in the background. 
“One moment please.” 
Struggling to keep a serious demeanour and in tune, he begins to sing: “I’ll sing you a song of the fish of the sea ...” 
That must be one of the daftest opening lines of any song, ever, and it defeats him. A hesitant pause is followed by a total breakdown into helpless laughter. All three of us. 
I suppose the lyrics of some of these songs are questionable these days, but not as questionable as the lyrics we used to sing on guitar nights in Leeds where I lived after leaving school, where familiarity with these songs gave me malign influence. Imagine four twenty-ish-year-old lads in a shared house with guitars and bottles of beer.  
Tavern in the Town became a song about the television rent collector who was a creep, and what he did with sheep. So did Camptown Races with the “doo-dah”s changed to “dildo”s. They are stuck in my head forever, and, of course, unrepeatable. Except for the one to the tune of The Ball of Kirrimuir about the owner of the house who knew we would never do any cleaning so did it all himself in return for us doing his washing up: 
Dave does all the cleaning, and that’s a job he hates, 
And so to appease him we have to wash the plates. 
… possibly the only case where our version was less deplorable than the original (although you won’t find any such words in the book). 
The News Chronicle Song Book 1931

The book has given sixty years of pleasure and continues to do so (perhaps that’s for a later post), more than twice as long as the original owner assuming she got it new when published in 1931. Who was she, I often wondered, the girl who misspelt “lose”? I never thought to ask. The wonders of internet genealogy reveal she was born in 1924, married someone called Roantree in 1951, moved in later life to Bridlington and died in 2010. By the time her book passed to us, she had three children of her own. I never knew them despite being of similar age and from the same area. She must have written the inscription in the nineteen-thirties. Did she ever think of it again? 
I don’t know if anything remains of Sycamore Farm. All I remember of Asselby is a village on a road to nowhere, on a tongue of heavy mudstone between the confluence of the Rivers Ouse and Derwent, where there was once an awkward bend through a disused railway crossing. I went once or twice to the Black Swan pub there but preferred the Kings Head at the end of the road in Barmby-on-the-Marsh. They had a better dartboard.

The phases of the Moon viewed looking southward from the Northern Hemisphere (Orion8, Wikimedia Commons)

Earlier this month, Sue in Suffolk mentioned on her blog that there are two full moons in October this year. The first was on the first: the Harvest Moon. I like her posts about country ways and the natural world. She even provides a link to a moon calendar in her sidebar.

Two or three days later, we were taking Mrs. D.’s new Fitbit out for an evening walk. She commented how white and bright the moon looked but that it did not seem quite full. I was able to respond that the full moon had been on the first of the month – “the Harvest Moon,” I said knowledgeably – and that there would be two full moons in October this year.

There ensued a discussion about how you could tell whether a moon was new or old, whether a J-shaped moon came before the full one and a C-shape after, or whether it was the other way round. It turns out to be JC in the Northern Hemisphere, which seems easy enough to remember.

How on earth have I got this far without knowing that?

Diaries always used to contain little symbols for the phases of the moon: ☽ ☾ and for first quarter, full, last quarter and new (assuming your browser renders these symbols correctly). There are none in my present diary (I still use a paper one), nor on the kitchen calendar. A diary from 2000 does not have them either. I had to look back to one of my father’s from 1986. 

Needless to say, I never paid them much attention. At one time it would have been one of the most important things you needed to be aware of for planning work outside.

Traffic Cam

Truvelo D-Cam

I have been watching the post (or the mail if you call it that) in trepidation.

Recently, we took daughter back to university: you can’t do art studio and ceramics stuff at a distance online. So she has to chance it with our hurdy gurdy covid policy – let all the students catch it otherwise we’ll have to bail out the universities, and the private landlords will go bust and we can’t upset them because they vote for us and donate money, and we’ll just have to cross our fingers that not too many students develop serious chronic health conditions.

Anyway, that’s a digression. On the way back, after leaving the motorway, you have to run the gauntlet of speed cameras. I know where they are and have learnt to be careful, but you know how it is: you have been going along at 70 and have to re-adjust to slower roads, and you are tired after five hours driving and are nearly home, and perhaps you relax too much and don’t pay enough attention. I got through most of the cameras unscathed but was left wondering about the really nasty one which is obscured by bushes just after the speed limit changes from 40 to 30. It is one of those high-tech, bi-directional Truvelo D-CAMs with no flash and hardly any road markings. I was watching out but when I thought about it again it was half a mile behind and I had crept back above 30 with no memory of passing the camera or checking the speed.

I hate the things. They caught us on Lendal Bridge in York during the first week it was restricted to buses and taxis only. There were few signs or road markings. By the time we realised where we were going there was no alternative but to proceed across. A similar thing happened in Newcastle. We found ourselves unable to turn round with a choice of either entering a private car park or going through a ‘bus gate’. At least they provide nice photographs of you driving where you shouldn’t. And at least Newcastle let us off with a first-time warning, and York council had to refund the penalty after the Lendal Bridge restrictions were challenged and judged unlawful.

Penalty Notice, Lendal Bridge, York     Bus gate penalty warning, Newcastle

Remember how it used to be? There was a time near Selby in the blue mini (see blog header), in the days before servo-assisted anti-lock brakes, when, foot-down, I came round a bend to see a parked car on my side of the road and a bus coming towards me. I scraped past with a deep scratch along the side. There wasn’t a mark on the parked car but the man who had been peeing behind it had a dripping wet trouser leg. It gave new meaning to the phrase “making a run for it”.

In a later car, when I lived in north-east Scotland, I would do the 750-mile round trip home several times a year. In those days you could dash along for miles at ninety without much fear of offending the police. I once managed the one-way trip, with one rest stop and one petrol stop, in less than six hours. The smooth slate-grey colour of my exhaust pipe was the envy of every motor sport fan. On other occasions, when there was no traffic on the three miles of gradual descent on the motorway between Sheffield and Doncaster, that little car could do a hundred.

Still later, in 2001, I had a new Golf funded by travel expenses. Once it was well run-in I wondered how fast it could go but chickened out at a hundred and twenty (193 km/h) on the M1 south of Sheffield. Nowadays, the cameras would have you straight away, followed by a court appearance, a heavy fine and disqualification. Do it too many times and you would go to prison.

I only did that kind of thing a few times and would not do it at all now. These days, there is no alternative but to observe the limits. That’s a good thing. I know of too many tragedies to think otherwise. And I do try to keep to the limits all the time, we both do, particularly since someone close had to go on a special course after getting caught by a camera.

The university trip was nearly three weeks ago. You should be informed of camera transgressions within fourteen days. The post lady has just walked by. Nothing for us. I think I’m safe for now. But, it’s probably only a matter of time.
