Grade Inflation

Posted in Education, Politics with tags , , , on August 12, 2010 by telescoper

Still too busy to post anything too substantial, but since this year’s A-level results are out next week – with the consequent scramble for University places – I thought I’d take a few minutes to share this  graph (taken from an article on the BBC website) which shows the steady dumbing-down improvement of educational standards student performance over the last few decades.

Nowadays, on average, about 27 per cent of students taking an A-level get a grade A. When I took mine (in 1981, if you must ask) the fraction getting an A was about 9%. It’s scary to think that I belong to a generation that must be so much less intelligent than the current one. Or could it be – dare I say it? – that A-level examinations might be getting easier?

Looking at the graph makes it clear that something happened around the mid-1980s that initiated an almost linear growth in the percentage of A-grades. I don’t know what will happen when the results come out next week, but it’s a reasonably safe bet that the trend will continue.

I can’t speak for other subjects, but there’s no question whatsoever that the level of achievement needed to get an A-grade in mathematics is much lower now than it was in the past. This has been proven over and over again. A few years ago, an article in the Times Higher discussed the evidence, including an analysis of the performance of new students on a diagnostic mathematics test they had to take on entering University.  The same test, covering basic algebra, trigonometry and calculus, had been administered every year so provided a good diagnostic of real mathematical ability that could be compared with the A-level grades achieved by the students.  They found, among other things, that students entering university with a grade B in mathematics in 1999 performed at about the same level as students in 1991 who had failed mathematics A-level.

The steadily decreasing level of mathematical training students receive in schools poses great problems not only for mathematics courses, but also for subjects like physics. We have to devote so much more time on the physics equivalent of “basic training” that we struggle to cover all the physics we should be covering in a degree program. Thus the dumbing down of A-levels leads to pressure to dumb down degrees too.

That brings me to the prospect of huge cuts – up to 35% if the stories are true – in government funding for universities, leading to pressure to shorten the traditional three-year Bachelors degree to one that takes only two years to complete. If this goes ahead it won’t be long before a student can get a degree by achieving the same level of knowledge as would have been displayed by an A-level student 30 years ago. Are we supposed to call this progress?

Or perhaps this business about two year degrees all really  does make sense. Maybe we should just accept that universities have to offer such courses because the school system has become broken beyond repair over the last 30 years, and it will be up to certain Higher Education institutions from now on to do the job that school sixth-forms used to do, i.e. teach A-levels.

Hothouse Flowers

Posted in Literature, Poetry with tags , , , , on August 11, 2010 by telescoper

At the weekend I shifted quite a lot of stuff around the house, in preparation for a major redecoration project in my main bedroom, which, when it gets started, means I’ll be sleeping in the spare room for quite a while. I moved a whole case of old paperback novels I’ve kept since I was a teenager and couldn’t help opening one that happened to be at the top. It was An Alien Heat, the first novel in the classic Dancers at the End of Time trilogy by Michael Moorcock whose books I devoured voraciously when I was at school. At the front of this one is a quotation from a poem by Theodore Wratislaw which contains the title phrase. I had a quick google about and found the whole poem, which turned out to be a very sensual and well-constructed sonnet, as opposed to the cack-handed parody I put up recently. The title of this poem also of course furnished the name of a well-known band.

I hate the flower of wood or common field.
I cannot love the primrose nor regret
The death of any shrinking violet,
Nor even the cultured garden’s banal yield.
The silver lips of lilies virginal,
The full deep bosom of the enchanted rose
Please less than flowers glass-hid from frost and snows
For whom an alien heat makes festival.
I love those flowers reared by man’s careful art,
Of heady scents and colors: strong of heart
Or weak that die beneath the touch of knife,
Some rich as sin and some as virtue pale,
And some as subtly infamous and frail
As she whose love still eats my soul and life.

Dizzy on the BBC

Posted in Jazz with tags , , , , on August 10, 2010 by telescoper

It’s a grey  gloomy and rainy August lunchtime here in Wales and so I thought I’d just try to brighten things up a little by posting this video of a lovely set by the quintet led in the early 60s by the great Dizzy Gillespie, clearly enjoying himself  on the BBC TV program Jazz 625. This was the band that also featured the brilliant James Moody on saxophones and flute. As you can hear, they played music that was strongly flavoured by Dizzy’s lifelong interest in Cuban jazz. The programme was introduced by the late great Humphrey Lyttelton and it’s in several bits which you will have to click through if you want to see them all. I hope you at least go as far as Part 3, where there’s a big laugh waiting for you…

Notes for the Reader

Posted in Uncategorized on August 9, 2010 by telescoper

I’m going to be too busy to post much this week so I thought I’d take the opportunity to point out a couple of things for the benefit of regular readers, newcomers and occasional visitors to this blog.

First, about RSS Feeds. If you wish to subscribe to the whole blog via an RSS feed you will find it at

https://telescoper.wordpress.com/feed/

If you wish only to see posts in a particular category, you can do so via

https://telescoper.wordpress.com/category/categoryname/feed/

So if, for example, you only want to read the “Science Politics” items via RSS the feed is at

https://telescoper.wordpress.com/category/science-politics/feed/

A full list of categories, together with the number of posts so far published in each one, can be found on the home page. You can use this to browse my back catalogue, so to speak, although I should point out that I didn’t file that many of my earlier posts in categories and haven’t had time to go back through them and sort them out…

I also wanted to make some comments about comments. Please note what it says on my home page:

Feel free to comment on any of the posts on this blog but comments may be moderated; anonymous comments and any considered by me to be abusive will not be accepted.

You may use a nickname or anonymous handle on a comment, but I insist on a valid email address that identifies you (although the email address will not be visible to anyone but me). The system that operates on comments is that, if you haven’t posted before, your comment will be held until I have approved it. Comments are posted immediately from “approved” users but I reserve the right to moderate them if they turn out to be abusive. Serial offenders are put on a blacklist and their comments will be treated as spam.

Even if you are a regular commenter you may find that some comments don’t appear straight away. That is because I operate a spam filter – spam comments outnumber genuine ones by more than two-to-one – and it sometimes makes mistakes. If this happens it is probably because your comment contains several embedded URLs, which makes the spam filter suspicious. I usually manage to rescue comments blocked in this way, but it may take a while before your comment appears.

Let me point out that there is a separate RSS feed for comments at

https://telescoper.wordpress.com/comments/feed/

if you wish to follow discussion that way.

I realise that there isn’t really a convenient way to communicate suggestions for improvements or to ask general questions about the blog, so when I have a bit of time I’ll set up a permanent page to serve that purpose.

Well, having got the positive discrimination out of my system (at least for today), I’ll add just one more. I’ve always been struck by the similarity between distinguished former Chief Executive of PPARC, current Chief Executive of the Scottish Universities Physics Alliance and President of the European Research Council, Professor Ian Halliday and actor Jim Broadbent.

I’m aware of the gender imbalance so far in my lookee-likee series, but here’s a step in the right direction courtesy of Rob Simpson (aka orbitingfrog). Have you noticed the resemblance between astronomer (and blogger) Sarah Kendrew and actress Julia Roberts? I wonder if by any chance they might be related?

Postscript: The Bombing of Alnmouth

Posted in Biographical, History with tags , on August 7, 2010 by telescoper

I realised late last night that, in writing yesterday’s account of the air raid on North-East England in August 1940, I had forgotten to mention the reason why I started reading about this particular event. I think it might be interesting to a few people so have decided to put up a short postscript today.

My Uncle George, my late father’s older brother, lives in the picturesque coastal village of Alnmouth in Northumberland. It’s a lovely little place, not far from the market town of Alnwick (which in 2002 was voted the best place to live in Britain by Country Life magazine; it’s always been popular with the huntin’ shootin’ fishin’ crowd). The countryside around is spectacularly beautiful and full of historical interest; Alnwick Castle is particularly interesting. Alnmouth itself is a small port, with a number of splendid pubs and places to eat, and is well worth a visit if you’re in the area. In fact, I intend to move to that part of the world when I retire (if I live that long).

Anyway, Uncle George lives in Argyle Street in the centre of Alnmouth but I was quite surprised to see that the street has a few modern dwellings when virtually every property in the town is quite old, most of the others being of traditional stone construction like so many houses in Northumberland. It turns out that Argyle Street was bombed during World War II and that the new houses were built to replace several that had been destroyed.

It seemed strange to me that the Luftwaffe would bother bombing a tiny place like Alnmouth, so I decided to see what I could find out about the event. Knowing a little about the huge raid I described yesterday, I assumed that it might have been a German bomber involved in that particular raid, jettisoning its load in order to evade an RAF fighter. So I found as many books as I could and started reading about the Battle of Britain, which I found fascinating. Hence yesterday’s post.

However, it turns out that the bombing of Alnmouth in fact took place over  a year later, on Saturday 8th November, 1941 at 19.20:

Two bombs on Alnmouth Village; one on a house in Argyle Street, the other in the roadway (a cul-de-sac). People trapped – still digging for four adults and three children believed buried. Later – five missing presumed dead, two died in hospital and twenty were injured. The bodies of a woman identified, also that of a man believed to be a Major Hawkes. Another woman’s body recovered later. Three houses demolished, eleven uninhabitable and many others damaged badly.

The bombs killed seven people, in fact; one man and six women. It was clearly a traumatic event for the people of the village and one which has left a scar to this day.

At that time in the evening in November it would have been dark, and it is thought that the bombing must have resulted from a failure to maintain the wartime blackout that was usually strictly enforced. Initially the blame was attached to two buses at terminus in Argyle Street whose headlights were thought to be reflecting in the water.

It’s still not clear what this plane actually was or what it was doing there on its own. It might have been on a reconnaissance mission, although that seems unlikely given that it was dark and would have been dark for some time; the sun would have sets around 16.15 at that time of year in Alnmouth, three hours before the bombs were dropped. It is more likely to have been part of a larger raid going elsewhere that noticed a light and went for what they call “a target of opportunity”.

PS. Almnouth is just a few miles North of Acklington, which featured prominently in yesterday’s post.

The Day the War came to Tyneside

Posted in Biographical, History with tags , , , , , , , , on August 6, 2010 by telescoper

We’re now approaching the 70th anniversary of August 15th 1940, the day that most historians regard as the start of the Battle of Britain. There had been a great deal of aerial combat, especially over the English Channel, in the weeks following the fall of France and the evacuation from Dunkirk in 1940, but August 15th was the day when the German Luftwaffe initiated a series massive daytime raids aimed at knocking out Britain’s air defences. Over the following weeks they nearly succeeded. It was only an erroneous change of tactics by the Luftwaffe, away from targetting the airfields and towards the terror bombing of cities, that gave the Royal Air Force time to recover from the punishment it had been taking. Eventually, by late September 1940, the threat of invasion, which at one point appeared imminent, had finally subsided.

I’m sure there will be many commemorations of the Battle of Britain over the next week or so, in which tributes will be paid to the few of The Few that survive to this day and, of course, those that gave their lives in the momentous struggle which happened all those years ago. There will be much talk of famous places such as Kenley, Northolt and Biggin Hill,  key sector airfields for 11 Group, responsible for defending London and the South East, which were under massive attack on August 15th and over the following days and weeks.

But it wasn’t just the South-East that was attacked on August 15th 1940. An enormous incoming raid from the North of France was met by Spitfires and Hurricanes of 10 Group and a terrifying dogfight involving about 200 aircraft brewed up over Portland. Further North, 12 Group’s defences were probed by bombers flying from Denmark intent on destroying airfields in Yorkshire.

And then there was 13 Group, which was charged with the task of defending Scotland and the North-East of England. The map below (courtesy of the RAF website) shows the location of their principal airfields and radar installations in 1940. The Operations HQ for 13 Group, RAF Newcastle,  was in Kenton, not far from the location of what is now Newcastle Airport. In fact I cycled past the place countless times when I used to work at Cramlington without knowing what it was. Then it was opened to the public for a time and all the maps, charts and telephones were still there. I felt a distinct shudder when I saw it.

I’ve always been fascinated by history. I read a lot of books about it and in Britain you’re never very far from the site of some historical event, perhaps a castle or the site of a bloody battle. Whenever I travel I also try to visit places of historical interest. Reading is fine, but there’s no subsitute for being there and seeing it for yourself.

It’s quite a different matter when history comes after you rather than you going to find it. The idea that such a familiar place (to me) as Kenton could have been so central to the epic struggle that was the Battle of Britain brings it home that the things we take for granted haven’t always been so secure. When I was a kid growing up in Newcastle, Biggin Hill seemed to me as distant as Dunkirk or El Alamein, but the idea of German planes flying over such places as the Farne Islands and Tynemouth is something that still gives me the shivers. I’m sure the people of Iraq felt the same way about the American and British planes that bombed their country during the two Gulf Wars…

I’ve therefore decided to post the following short account of some of what happened on August 15th 1940 in my own neck of the woods, partly because of what I said in the previous paragraph and partly because the numerical facts are are pretty representative of the situation all around the country on that day seventy years ago. I got the details from a book called The Narrow Margin by Derek Wood and Derek Dempster, and you can find a more complete report here where there is a full account of every day’s action during the Battle of Britain.

For a start it appears that the Luftwaffe thought that most of Britain’s fighter defences were committed to the South. They were probably aware of the effectiveness of the long-range Radio Direction Finding (RDF, now known as radar) network known as Chain Home, but disregarded it because they thought there would not be many planes around to intercept them even if they were detected. The raid over Tyneside was despatched from Stavanger in Norway and flew in a roughly south-westerly direction across the North Sea.

At 12.08, RDF trackers began to plot the path of a formation of “twenty plus” incoming aircraft opposite the Firth of Forth at a range of over 90 miles. As the raid drew closer, the estimated number was revised up to thirty, in three sections, approaching from the North-East and heading SW towards Tynemouth.

The radar operators of 13 Group hadn’t had as much practice as their colleagues further south in 11 Group, which probably accounts for the difficulty they had in estimating the number of incoming planes. Nevertheless, with a full hour’s warning, the controller was able to put squadrons in excellent positions to attack, with 72 Squadron Spitfires in the path of the enemy off the Farne Islands and 605 Squadron over Tyneside. Nos 79 and 607 were also put up, but while the latter was in the path of the raid, No. 79 was initially too far north.

No. 72 Squadron from Acklington was the first to make contact, seaward of the Farne Islands. Closing rapidly with the incoming aircraft, it came as a distinct shock when the “thirty” materialised as sixty-five Heinkel 111s and thirty-four Messerschmidt-110s (or ME110s for short), i.e. almost a hundred aircraft. The RAF squadron facing them comprised a mere 11 Spitfires.

When I first read the numbers involved I could hardly believe them. Imagine being outnumbered almost ten to one, but knowing that you had no choice but to attack. Reading through the RAF daily reports makes it clear that these odds were by no means unusual. Time and time again during August 1940, a squadron or half a squadron would be scrambled to meet inbound formations of 100-plus aircraft. Although the RAF pilots were both brave and skillful, facing such an overwhelming weight of numbers against them it was inevitable that the attrition rate would be high. It was the steady loss of pilots, rather than planes shot down, that almost brought the RAF to its knees.

The only chance of an effective defence a small group of fighters could offer was to scatter the massed formation by attacking from the front, trying to disrupt them so much that they would not find their targets inland. That was the plan anyway; it didn’t always work. In the absence of a Squadron-Leader, 72 Squadron was led by Flight-Lieutenant Edward Graham, who, as it turned out that day, led one of the most spectacularly successful air combats of the War.

Thirty miles off the coast, the squadron sighted the enemy.  As the RDF stations had predicted, the Germans were flying in three formations – the bombers ahead and the fighters in two waves stepped up to the rear. Misled by the supplementary fuel tanks slung below their wings, which looked like bombs, Graham and his pilots took the closer wave for Junkers 88 bombers whereas they were in fact (twin-engined) ME110s of the fighter escort.

The incoming formation was so vast in comparison with Graham’s small force that he hesitated for a moment, uncertain at what point and from what direction to attack.  Apparently unable to bear the suspense, one of his pilots asked him whether he had seen the enemy aircraft. With a stutter which was habitual, but which deteriorated in times of stress, he replied

Of course I’ve seen the b-b-b-bastards, I’m trying to w-w-w-work out what to do.

The reply was to became famous throughout Fighter Command. I don’t blame him for stuttering. If it had been me I would have been filling my pants.

But he didn’t hesitate for long. The Spitfires had had plenty of time to gain height during their long flight from the coast, and were about three thousand feet above the enemy’s mean height.  Making the most of his advantage, he decided to lead the squadron in a deliberate frontal attack, diving out of the Sun to achieve maximum surprise. Each pilot was free to choose his own target.  Two-thirds attacked bombers or supposed bombers, the remaining third the second wave of fighters, correctly identified as ME110s.

The attack was startlingly effective and caused widespread panic among the German planes whose pilots had been told not to expect that much opposition.  Jettisoning their external tanks, some of the ME110s formed a defensive circle, while others dived almost to sea level and were last seen heading East.  The bombers, less an indeterminate number destroyed by Graham’s squadron, then split into two formations, each accompanied by some of the remaining fighters. One formation headed for Tyneside, apparently with the intention of bombing the sector station at Usworth; the rest turned South-East towards two aerodromes at Linton on Ouse and Dishforth which they had been ordered to attack. Some of them jettisoned their bombs and headed back to Norway, leaving several of their number in the sea.

The separate parts of the remaining formation finally reached the coast, one near Acklington and the other south of Sunderland. The first formation, engaged successively by the remaining (No. 79) squadron from Acklington, the triple-A batteries defending the Tyne area, and some Hurricanes of 605 Squadron which had come south from Scotland, dropped most of their bombs in the sea. The second, engaged by a squadron of Spitfires from Catterick, a Hurricane squadron from Usworth and the anti-aircraft artillery from the Tees batteries, dropped theirs almost as ineffectively near Sunderland and Seaham Harbour.

Overall, backed by the guns of the 7th Anti-Aircraft Division under Major-General R.B. Pargiter, 13 Group’s aircraft destroyed at least eight Heinkels and seven 110s without suffering a single casualty themselves, although several civilians were killed by bombs and there was considerable damage on the ground, including a few airfields. It is known that, in addition to the enemy losses reported during this period, many German aircraft struggled back to their bases with battle damage and some were written off after crash-landings.

This was one of the most successful actions fought during the entire Battle of Britain and its effect was that that 13 Group met no further daylight raids for the duration. However, it was just one episode in a struggle that became increasingly desperate as the summer of 1940 dragged on. As I said at the start, the defences of 11 Group came particularly close to breaking point, but eventually recovered and the expected invasion never materialised.

The rest, as they say, is history…
