Waking to the news that Colin Firth won the Best Actor Oscar for his role as George VI in The King’s Speech, I thought it would be fun to consider outstanding acting performances that for one reason or another didn’t win an Oscar.
My nomination is for Sean Connery’s spellbending performance as Brother William of Baskerville in The Name of the Rose (a “palimpsest” of Umberto Eco’s novel of the same title). In fact you can watch the whole film (in pieces) on Youtube:
Other nominations through the comments box please!
It’s been a while since I posted anything about crosswords, so the fact that I saw my name in today’s Observer gives me an excuse to do so now.
First, I was delighted to get another point for a Very Highly Commended (VHC) clue in the ongoing Azed clue-setting competition. The latest competition puzzle was Azed No. 2019. This was an interesting one, incorporating a variation on the “Plain” Azed puzzle in that the 12 by 12 square grid was actually divided vertically into two rectangular puzzles side-by-side. Clues for each half of the resulting “Right & Left” puzzle were run together, usually without punctuation, and with either side coming first. Solvers had to determine the location of the join between the clues, solve each part, and then figure out which side of the puzzle the answers had to go. I think it was a very enjoyable puzzle, with Azed’s skill strongly in evidence not only in constructing the clues but also in disguising the splices.
The two words for which clues were invited for the competition were OVERAWE and HENOTIC; the latter is a fairly unfamiliar term, defined in the puzzle as “tending to unify”. The clue that won me a VHC was
Cow or ewe cooked with odd bits of veal serving to make one nice hot stew?
Here I’m using “cow” as a definition of “OVERAWE”, with subsidiary anagram of OR+EWE+VA (odd bits of VEAL), with “cooked” as an anagram indicator; “serving to make one” defines HENOTIC, clued with another anagram NICE+HOT, with anagram indicator “stew”. I think it’s an easy clue, but I was quite pleased at the way the two halves run into each other to produce a reasonable surface reading. Above all, I think it’s fair – no superfluous words and no dodgy syntax.
Anyway, I’ve now got 3 VHC mentions this year, which is as many as I’ve ever won in the annual competition, so if I can just get one more it will be a personal best. There are 5 puzzles remaining this year, so maybe I’ll manage it!
A few weeks ago I won a prize in the Everyman crossword competition – also in the Observer. This is a much more straightforward puzzle than Azed and I usually do it more as a warm-up exercise than anything else but still post the completed grid off every week. One day last week I came home from work to find a note from DHL saying that they’d left a package with my next-door neighbour. It turned out to be a package of Penguin books: a Concise English Dictionary; a Concise Thesaurus; a Dictionary of Proverbs; a Dictionary of English Idioms; and the Penguin Book of Facts (a kind of encyclopedia). Anyone who’s been to my house knows that I have no shortage of dictionaries already, but I’m pleased with the others.
I finished this week’s Everyman just before starting to write this post. For the second week running there’s a clue formed by an indirect anagram. In this instance it is:
End of game inventor reviewed (2-4)
The answer is NO-SIDE (the signal indicating the end of a rugby match). The subsidiary indication is an anagram of EDISON (“inventor”). This is called an indirect anagram because the letters to be formed into the anagram do not actually appear in the clue. Most British setters frown upon this type of clue, not because they are hard – the one above certainly isn’t difficult to solve – but because they aren’t Ximenean and are therefore unfair. Azed would certainly never countenance such a clue, though an increasing number of setters – especially those for the Grauniad – seem to adopt a much more libertarian approach.
My copy of the Times Higher arrived a little late this week, so I’ve only just seen the latest evidence that the Westminster government’s plans for English Higher Education are degenerating into farce.
For a start it seems that the government made a serious error in believing that the Office For Fair Access (known to its few friends as OFFA) actually doesn’t have the legal authority to impose fee levels on universities. The government had assumed that they would be able to prevent all universities charging the maximum £9K allowed under the new rules. But they can’t.
Since the increased tuition fee is being offset by cuts of up to 80% in teaching budgets it’s no surprise that universities want to maximise the income from fees. Oxford, Cambridge, Imperial College and UCL have all already indicated that they will go for the maximum, which isn’t surprising since these are among the leading universities in the country. It may be that some universities, perhaps from the ex-Poly sector, might try to go for the `pack ’em high and sell ’em cheap’ approach to undergraduate degrees, but a more challenging issue is what the middle-grade universities will do. Will they try to compete on price, or will they fear that charging less than £9K will get them branded as second-rate?
However, if all universities charge £9K – which has always seemed to me to be the most likely outcome – then this costs the government much more than it anticipated, because it has to provide a much higher amount in loans. David Willetts has argued that the £9K limit is `difficult to defend’, claiming that despite the cuts a fee of this size would lead to a 40% increase in teaching resource. This isn’t actually true because universities will have to devote a large slice of the fee income to supporting less-well-off students and they are also being hit by huge cuts in capital funding, which will have to be made up some way. Methinks Willett’s famous two brains might have got their wires crossed.
Whether the £9k level is defensible or not, the government appears powerless to stop universities charging it, so is threatening to penalise research grants or to cut the number of student places if too many try it. This looks like panic to me.
The current state of British Higher Education policy is difficult to defend in other ways too. In among the figures spun out by Willetts is one that reveals that 80% of UK students are in subjects outside the area of Science, Technology, Engineering and Mathematics (STEM), which attract a lower level of central funding than STEM disciplines. However, the differential is not as large as you might think: there’s only a factor two between the lowest band (D, including Sociology, Economics, Business Studies, Law and Education) and the STEM band B (including my own subject, Physics). The real difference in cost is much larger than that, and not just because science subjects need laboratories and the like.
To give an example, I was talking last week to a student from a Humanities department at a leading University (not my employer). Each week she gets 3 lectures and one two-hour seminar, usually run by a research student. That’s it for her contact with the department. In my School, a typical student can expect around 20 contact hours per week including lectures, exercise class, laboratory sessions, and a tutorial (usually in a group of four). The vast majority of these sessions are done by full-time academic staff, not PDRAs or PhD students, although we do employ such folks in laboratory sessions and for a very small number of lectures. It doesn’t take Albert Einstein to work out that 20 hours of staff time costs a lot more than 3, and that’s even before you include the cost of the laboratories and equipment needed to teach physics. In the current system, however, students pay the same fee for STEM and non-STEM subjects.
This situation not only works as a powerful disincentive for a university to invest in expensive subjects, such as physics, but also rips off arts students who are given very little teaching in return for their fee. It is fortunate for this country that scientists working in its universities show such dedication to teaching as well as research that they don’t try to do what our cousins in the arts do. I sense a growing consensus, however, that we’re being ripped off too.
I suppose it could be argued that the big cuts in teaching grant in England do something to redress this anomaly, as the central funding element for Arts & Humanities subjects is cut to zero in the new funding regime. On the other hand, however, if universities do charge £9K for all subjects then the differential between arts and sciences will turn out to be lower than 2:1, as the central funding element for STEM subjects is far less than £9K. On the other other hand, if STEM subjects were to charge a higher fee than the others then demand would probably collapse.
To get another angle on this argument, consider the comments made by senior members of the legal profession who are concerned about the drastic overproduction of law graduates. Only about half those doing the Bar Professional Training Course after a law degree stand any chance of getting a job as a lawyer in the UK. Contrast this with the situation in science subjects, where we don’t even produce enough graduates to ensure that schools have an adequate supply of science teachers. The system is completely out of balance.
I don’t see anything in the post-Browne era that will alter this ridiculous situation. STEM subjects will continue to be strangled and universities will continue to overproduce graduates in other areas. Somebody has to get a grip. I doubt the Westminster government is capable of doing this. It has already delayed its planned White Paper on Higher Education, providing yet another indication that it has completely lost the plot.
Or maybe it’s making a complete botch of the situation deliberately, as part of a cunning plan to encourage universities to go private?
When I first arrived at Cambridge University (nearly 30 years ago) to begin my course in Natural Sciences, eventually leading to a specialism in Physics, one of the books we were all asked to buy was the Cavendish Problems in Physics. One of the first problems I had to solve for tutorial work was from that collection, and I have been setting it (in a slightly amended form) for my own students ever since I started lecturing. I thought I’d put it up here because I think there might be a few budding theoretical astrophysicists who’ll find it interesting and because it provides a simple refutation of a crazy theory that has been doing the rounds on Twitter all morning.
I like this problem because it involves a little bit of lateral thinking, because not all the information given seems immediately relevant to the question being asked, but you can get a long way by just writing down the pieces of information given and thinking about how you might use simple physical ideas to connect them to the answer.
If you haven’t seen this problem before, why not have a go?
Using only the information given in this Question, estimate the ratio of the mean densities of the Earth and Sun:
i) the angular diameter of the Sun as seen from Earth is half a degree
ii) the length of 1° of latitude on the Earth’s surface is 100km
iii) the length of a year is 3×107 seconds
iv) the acceleration due to gravity at the Earth’s surface is 10 m s-2.
HINT: You do not need to look up anything else, not even G!
The answer you should get is that the mean density of the Earth is something like 3.5 times that of the Sun, although the information given in the question isn’t all that accurate.
In fact the mean density of the Earth is about 5500 kg per cubic metre, and that of the Sun is about 1400 kg per cubic metre; the average density of the Sun is just 40% higher than water, which is perhaps surprising to the uninitiated….
The density of solid iron on the other hand is about 7900 kg per cubic metre, and even higher than that if it is compressed…
UPDATE: I’ve added my Solution.
Not many people know that the “A” in Professor John A Peacock actually stands for “Acker” (i.e. Peacock is aka Bilk), although it’s clear the reason he’s not better known as a clarinettist is his failure to wear the appropriate form of hat.
I’ve also included a recording of the man himself playing a medley of his hit, Stranger on the Shore, accompanied by a selection of photographs of Cardiff Bay:
I recently received an anonymous tipoff (from Haley Gomez) drawing attention to the remarkable similarity in visual appearance between esteemed Plumian Professor of Astronomy and Experimental Philosophy at the University of Cambridge Rob Kennicutt and the Muppet Show’s resident comedian Fozzie Bear. I hear they sound similar too! I wonder if by any chance they might be related?
