Mornington Crescent versus the Computer

Posted in Uncategorized with tags , on August 29, 2011 by telescoper

It seems appropriate to follow my rambling dissertation about the bygone age of London’s railways with an analysis of the following example of the classic game Mornington Crescent, in which experienced human players (and Stephen Fry) pit their wits against a computer. Mortimer’s Variation  often leads to rather defensive strategies amongst inexperienced players, and is for that reason not recommended at club level. However amongst top players the constant danger of offside on the parallels playing this version of the rules simply encourages exploration of   the diagonal moves eschewed by the less adventurous. Notice newcomer Stephen Fry, sitting West, whose daringly unorthodox  shift to West Hampstead clearly tested  the computer’s software to breaking point. Unlike the much simpler game of chess, it will be some time before computers can compete with the greatest human exponents of Mornington Crescent…

ps. Asking “Is it my go?” is also frowned upon in Bridge, I find, especially at competition level…

pps. Notice also the letter from  Mrs Trellis, a regular contributor to Andy Lawrence’s Blog and email correspondent of Prof. Mike Disney.

Those long uneven lines
Standing as patiently
As if they were stretched outside
The Oval or Villa Park,
The crowns of hats, the sun
On moustached archaic faces
Grinning as if it were all
An August Bank Holiday lark;
And the shut shops, the bleached
Established names on the sunblinds,
The farthings and sovereigns,
And dark-clothed children at play
Called after kings and queens,
The tin advertisements
For cocoa and twist, and the pubs
Wide open all day;
And the countryside not caring
The place-names all hazed over
With flowering grasses, and fields
Shadowing Domesday lines
Under wheats’ restless silence;
The differently-dressed servants
With tiny rooms in huge houses,
The dust behind limousines;
Never such innocence,
Never before or since,
As changed itself to past
Without a word–the men
Leaving the gardens tidy,
The thousands of marriages
Lasting a little while longer:
Never such innocence again.

by Philip Larkin (1922-1985).

I came across this while searching for a poem to post on an August Bank Holiday  (because today is one of those). I hadn’t expect to find something like this though! Larkin isn’t known as a war poet, but I find his detachment and use of irony in this poem- e.g. comparing the lines of men in the trenches to those queuing to watch cricket or football – as devastating as some of the more obviously visceral works of the genre.

Murder on the Railway

Posted in History, Literature with tags , , , , , , , , on August 28, 2011 by telescoper

I recently finished reading a book called Mr Briggs’ Hat by Kate Colquhoun, “a sensational account of Britain’s first railway murder”. In fact the subtitle isn’t particularly apt because this is a sober yet fascinating account of a famous Victorian crime, the investigation and trial that followed it. It’s a gripping story because it involves not only the elements of the classic “locked room” murder mystery, but also the pursuit of the suspect across the Atlantic to New York.

I won’t describe the story in full, as the details can be found in many places on the net. In a nutshell, the victim of this crime was a 70-year old well-to-do banker by the name of Thomas Briggs, who was found lying on the tracks of the North London Railway, between Bow and Hackney Wick (also known as Victoria Park) stations on the evening of 9th July 1864. He was carried to a nearby pub, but died later that evening of  extensive injuries to the head.

Briggs had boarded a first class compartment of the 21.45 train from Fenchurch Street station in order to travel to his home in Hackney. When the train had arrived at Hackney Central, at 22.10, one  compartment, with nobody inside, was found to be covered  in bloodstains; an empty leather bag and a walking stick were also found. It wasn’t hard to put two and two together;  some of Briggs’ possessions were found in the compartment, as was a battered hat. After Briggs’ death his family were asked to identify the various items that had been found, which they did, apart from the hat, which wasn’t his. Mr Briggs’ own hat had vanished.

All the evidence suggested that Briggs had been violently attacked and then thrown from the train. Perhaps he had tried to defend himself and in the course of a struggle had knocked off his assailant’s hat. In the rush to leave, or perhaps because his own was damaged, the murderer must have picked up the top hat Mr Briggs had been wearing. Briggs’ watch had apparently also been stolen.

After many false leads and a great deal of frustration the police finally developed a plausible suspect, an impoverished German tailor by the name of Franz Muller. Muller had apaprently been trying to raise money in order to travel to America and had in fact already boarded a ship to make the Atlantic crossing by the time the police were on his trail. However, Muller had travelled the cheapest way possible, on a sailing ship, steerage class.  Detective Richard Tanner, who led the police investigation, realised that if he travelled on a faster steamship he could still get to New York before Muller. So off he went, with a number of key witnesses in tow so he could produce them at an extradition hearing. This was all at the height of the American Civil War, incidentally, but the Muller case still made front page news in New York.

In fact Muller’s ship, the Victoria, took 40 days to reach New York – it must have been a terrible journey! – and Tanner arrived almost three weeks before that, so he had plenty of time to prepare to arrest his man. When Muller arrived he went meekly and when his possessions were searched the police found a watch with a serial number that matched Mr Briggs’. Muller also had a hat, but it didn’t quite match the description of the one belonging to Mr Briggs, as it had apparently been cut down. Such was the fame attached to this case that the style of a cut down top hat subsequently became universally known as a “”Muller” . Winston Churchill liked to wear one, apparently…

Anyway, Tanner secured the extradition warrant and returned to England with Muller, who was committed for trial at the Old Bailey and held on remand at Newgate. The trial lasted only three days, and it took the jury only 15 minutes to return a verdict of guilty. Muller was hanged at the public gallows at Newgate on November 14 1864. A huge crowd turned out to watch and there was so much disorder that the police feared a full-blown riot would break out. Such was the concern about this event that within a few years the practice of public executions was discontinued.

One of the reasons for the unrest at Muller’s execution was that there was a public outcry about the result of the trial. Many questions that had arisen during the trial had never been satisfactorily answered and Muller had continued to protest his innocence. He claimed that he had obtained the hat himself at a second-hand shop and had bought the watch in a similar fashion down at the docks, where stolen goods were regularly flogged. The law of the time, however, considered defendants on murder charges (and their spouses)  to be “incompetent witnesses”, which meant that they were not allowed to take the stand  in their own defence. Muller was therefore never given the opportunity to give his own account of what happened that evening. He had an alibi, in fact, that he’d spent the evening with a ladyfriend so she was called as a defence witness. It turned out however that she was a prostitute, and therefore lacking in credibility to a Victorian jury, and was also profoundly deaf. The prosecution tore her to shreds on the witness stand.

The compartment  in which the crime took place was a mess, with blood spatter and general signs of a disturbance. Why then did nobody else on the train hear anything? And how did Muller avoid getting any blood on his own clothes? A poor man like Muller would not have an extensive wardrobe, and his landlady (who also washed his clothes) hadn’t noticed any bloodstains on the night of the crime, or in the days afterwards before Muller left for New York. And how did he get off the train? Nobody saw him at Hackney station. Did he jump onto the tracks?

An important prosecution witness was a cab driver called Matthews, who testified to having helped Muller pawn various items. However, Matthews reliability was called into question when inconsistencies were found between his testimony on the witness stand and statements he had made earlier to the police. It also transpired that he was heavily in debt and clearly had his eyes on the reward that had been offered in connection with the murder. In fact it was £300, a huge sum in those days…

Another important question was raised at trial by  a railway employee who had noticed Mr Briggs, a regular passenger on the North London railway, on the train at Bow station in a first class compartment with not one but two other men, neither of whom matched the description of Muller (who was short of stature  and of slight build). The prosecution rubbished this testimony too, but it turns out that the police had found four other witnesses who had seen the same thing: Briggs in his compartment with two other men. In those days, however, the police were not obliged to disclose evidence to the defence if it was not used at trial. Had five independent witnesses all delivered corroborating testimony then there might well have been reasonable doubt about Muller’s guilt.

Above all, Muller just didn’t seem to behave like a murderer. He had told his friends well in advance of his departure for the United States, and had travelled in his own name without any attempt to conceal his identity. He was mild mannered and polite, on the small side, and not at all what the public expected of the perpetrator of such a violent crime. He was also quite small. Was he really capable of beating the much larger, if older, Briggs to death and then heaving his body out of the train all on his own?

All the evidence against Muller was circumstantial. No eyewitness put him on the train that night in 1864 and there was no forensic evidence to connect him with the crime scene. There was a bloody thumbprint on the hat left at the scene and a bloody handprint on the carriage door, either of which could have been conclusive, but decades were to pass before fingerprint analysis was to become an established part of forensic science. DNA or other trace evidence could of course also have been used to determine whether any of the blood in the carriage was Muller’s or even if he had worn either hat.

And what was Muller’s motive? Contrary to the suggestion that he was looking for money to allow him to move to New York, he seems to have had enough money already to pay for his ticket, because he had already bought it when the murder happened. It could have been an impulse. Perhaps he saw Briggs, who was wont to doze off on the train, and attempted to rob him but woke him up and a struggle ensued; but this seems very out of character.

However, the final words on this case should perhaps be those uttered by Muller himself just seconds before he took the drop. The prison chaplain, anxious for the confession that would bring closure to the case, stepped forward and asked “Did you do it?”. Muller reportedly answered, in German, “Ich habe es getan…”

Anyway, I found Mr Briggs’ Hat a fascinating read, fully of atmosphere and detail of the period and it yields fascinating insights into the social history of Victorian London. One of the things that got me especially interested in it was that the place it all happened is so close to where I used to live and work in the East End of London. On which note…

..I was curious about the route taken by Thomas Briggs from Fenchurch Street to Hackney, as no underground or overground railway goes that way nowadays. A bit of research (i.e. Google) revealed just how extensive the railway network was in the 1860s. Here is a map showing the relevant routes:

You can see that the service Mr Briggs took travelled in a roughly easterly direction out of Fenchurch street, along the route of the London and Blackwall Railway to Limehouse (the station there was named Stepney in those daysn, before swinging to the north. This railway is long since defunct but for much of its length this part of the route is followed by the modern Docklands Light Railway which carries on towards Poplar and London Docklands. However, the train Mr Briggs diverged from this route; it carried on  over the Regents Canal and across Burdett Road (where apparently there once was a station, although it didn’t open until 1871) before reaching Bow Station where it linked up with the North London Railway.  This part of the route doesn’t exist at all nowadays,  although there is still a railway bridge over Burdett Road carrying trains to and from destinations further to the east. Moreover,   “Bow Station” wasn’t either of the current stations at Bow (Bow Road, on the District and Hammersmith and City Underground lines or Bow Church on the Dockland Light Railway) but a much larger station which has now also vanished, but whose location you can  find next to the blue arrow on this map:

The line extending out of the top of the map is the route taken by the North London Railway at the time, essentially up the eastern side of Victoria Park, passing through Old Ford, before turning to the west to arrive at Hackney.

So what happened to this railway and all its stations? Well, if I tell you that they were all closed to the public in 1944 then you can probably guess. This part of London was heavily bombed during the Second World War, and not only during the Blitz. In fact Bow Station was hit by a V1 flying bomb and damaged beyond repair, but that was after operations on the North London Line had already been suspended because of bomb damage.

You can find a huge amount of fascinating detail about the disused stations on the North London Railway and elsewhere here.

A Kind of Brew

Posted in Jazz with tags , , , , , on August 27, 2011 by telescoper

Well here’s a find for fan’s of Miles Davis. I stumbled across this exceedingly rare clip of his 1969 band playing at Ronnie Scott’s Club in London, complete with an introduction by Ronnie Scott himself. It’s  rare, firstly, because Miles didn’t do many club gigs at this time (or after) and I have a feeling that this might be one of his last; he usually played big concert venues whenever he toured in later years. But an even rarer thing about it is that this is the legendary “Lost Quintet” of Miles (on trumpet, of course), Wayne Shorter on saxophone(s), Chick Corea (keyboards), Jack de Johnette on drums and Dave Holland on bass.

Filmed in November 1969, this performance took place just a few months after the recording sessions that give rise to the celebrated but controversial album Bitches Brew, which was released in April 1970. The band at Ronnie Scotts was a subset of the larger ensemble that made the album, but you can hear the similarity in musical style, heavily influenced by psychedelic rock…

And here, for completeness, is a fuller version of the title track of the album Bitches Brew, recorded just two days later in the Tivoli Concert Hall in Copenhagen.

Miles was obviously experimenting with a much freer form of improvisation at this time and both the album and this live performance seethe with a kind of wild passion that threatens to burst into anarchy at any moment. It’s not exactly easy listening, of course, and the live performance is inevitably rough around the edges, but I think it’s a fascinating bit of jazz history. And, for what it’s worth, I think Bitches Brew is completely and utterly brilliant..

When is a planet made of diamond not a planet made of diamond?

Perhaps when it’s a White Dwarf?

Perhaps when there’s not a shred of evidence that it’s actually made of diamond?

Yesterday Science announced the amazing discovery of an incredibly dense object that appears to be made of a crystalline form of carbon: possibly, ultra-dense diamond (Bailes et al. 2011, Science, DOI: 10.1126/science.1208890). The object orbits a recently-discovered pulsar, PSR J1719-1438, every two hours and ten minutes. It has a slightly higher mass than Jupiter (technically, its minimum mass), but the lack of evidence for direct interaction w … Read More

Are exams getting easier?

Posted in Education with tags , , , on August 26, 2011 by telescoper

With the publication of this year’s GCSE results there’s been the usual clamour about “dumbing down” of educational standards. So are these examinations getting easier or not? I can’t answer that question because I’m far too old to have done GCSEs. The examinations I took at the equivalent stage of my school career were O-levels. But, being an inveterate hoarder of useless articles, I kept the exam papers that I took, so what I can do is put up and example the O-level papers I took (in 1979) and let you decide. I thought the Mathematics one might be of interest, so here it is or rather here they are, because there were two 2-hour written papers; there was no coursework component, so these counted 100% of the final grade.

If you’ve done GCSE mathematics recently, have a look and see what you think!

(You can click on the images to make them bigger if they’re difficult to read…)

I’d be interested in any comments you might have, especially if you’ve actually done GCSE Mathematics (recently or a long time ago). I suspect the most obvious difference is that in my day we did much more geometry…

I might put up the Physics papers if there’s enough interest!

A Healthy Increase

Posted in Education with tags , , , on August 25, 2011 by telescoper

Up early again this morning, I thought I’d do a quick post because I just remembered that there’s a bit of a loose end I’ve left dangling for a week or so owing to my recent indisposition.

I posted about 10 days ago about my week as “responsible person” for the School of Physics & Astronomy at Cardiff University owing to the absence of all the really responsible people on their respective vacations. By sheer coincidence my week in charge spanned the day that A-level results were announced and therefore the period during which we finalised this year’s UCAS admissions process. I had thought this might be quite a stressful time because rather late in the day we were given a significant increase in funded student numbers by the Higher Education Funding Council for Wales (HEFCW) which made it necessary for us to enter the clearing system to find the extra students.

As it turned out however the prospective students to whom we’d made offers paid back our confidence in them and a large fraction got the necessary grades. We did go into clearing, but only briefly, to pick up a relatively small number of unattached applicants who matched our criteria. I’m happy to report, therefore, that we’ve got a very healthy intake of 120 students this year, up by about 30 on last year. That’s exactly the increase we had planned for and we can cope with it without making drastic changes, such as increasing the size of tutorial groups, that would remove the personal touch that makes this such a pleasant School to work and, I hope, study in.

The hard work done all year round by admissions teams in University departments tends to be drastically undervalued, so I’d like to take this opportunity to thank Carole Tucker for doing such a great job for the School of Physics & Astronomy, ably supported by Nicola Hunt. Where we’d be without them I don’t know.

Modesty forbids me, of course, from pointing out who was acting Head of School while this all came to fruition, and who therefore really deserves the credit….

Stellar Research?

Posted in Education, Science Politics with tags , , , , on August 24, 2011 by telescoper

I heard today that  Chief Scientific Advisor to the Welsh Government, John Harries, has called for Welsh universities to be more “predatory” in attracting “star researchers” to Wales. At first sight I thought that sounded like good news for astronomy, but reading the article more closely I realise that’s not what he meant!

The point is that, according to the BBC article,  Welsh universities currently only attract about 3% of the UK’s research funding whereas the famous Barnett formula allocates Wales about 5% of the total in other areas of expenditure.  Nobody involved in research  would argue for funds to be allocated on any other basis than through quality, so there’s no clamour for having research funding allocated formulaically a là Barnett; the only way to improve the success rate is to improve the quality of applications. John Harries suggests that means poaching groups from elsewhere who’ve already got a big portfolio of research grants…

The problem with that strategy is that it’s not very easy to persuade such people to leave their current institutions, especially if they’ve already spend years acquiring the funding needed to equip their laboratories. It’s not just a question of moving people, which is relatively easy, but can involve trying to replace lots of expensive and delicate equipment. The  financial inducements needed to fund the relocation of a major research group and fight off counter-offers from its present host are likely to be so expensive that the benefit gained from doing this takes years to accrue, even they are successful.

I agree with Prof. Harries that Welsh universities need to raise their game in research, but I don’t think this “transfer market” approach is likely to provide a solution on its own. I think Wales needs a radical restructuring of research, especially in science, across the whole sector, which I think is unacceptably complacent about the challenges ahead.

For a start, much more needs to be done to identify and nurture  younger researchers, i.e. future research stars  rather than present ones.  Most football clubs nowadays have an “academy” dedicated to the development of promising youngsters, so why can’t we do a similar thing for research? Research groups in different Welsh universities also need to develop closer collaborations, and perhaps even full mergers, in order to compete with larger English institutions.

More controversially I’d say that the problem is not being helped by Welsh universities continuing to be burdened by the monstrous bureaucracy and bizarre practices of the Research Excellent Framework, which allocates “QR” research funds according to priorities set by HEFCE in a way that reflects the thinking of the Westminster parliament. The distribution of QR funding in Wales, which is meant to supplement competitive grant income from UK  funding bodies, should be decided by HEFCW in line with Welsh strategic priorities. Wales would be far better off withdrawing from the REF and doing its own thing under the auspices of the Welsh Assembly Government.

What I’m saying is that I’ve got nothing against Welsh universities trying to entice prominent research leaders here;  we’ve recently tried (unsuccessfully) to do it here in the School of Physics & Astronomy at Cardiff University, in fact. But in the current funding climate it’s not easy to persuade their current institutions to let them go. In any case,  I don’t think parachuting in a few high-profile individuals will in itself solve the deep-rooted problems of the Welsh university system. A longer term strategy needs to be found.

Scotland already punches above its weight in terms of research income for its universities and there’s no reason why, in the long run, Wales can’t do likewise.
