The End of the Viva

Posted in Biographical, Education with tags , , , , , on June 13, 2012 by telescoper

I’m stuck at home today, waiting for UPS to come and collect a defective printer. Any time between 9am and 7pm, they said. Very helpful. Anyway, I’ve got plenty to do while I’m here, catching up on STFC Astronomy Grant Panel business that I’ve been too busy to attend to. Also, this week’s Private Eye has just arrived in the post, so I’ll take a break at some point to do the crossword by Cyclops. It’s a lovely day. Pity I can’t sit in the garden. I’d miss the doorbell when the carrier arrives.

Anyway, the past two days have been largely given over to the business of examinations in the School of Physics & Astronomy at Cardiff University. The External Examiners spent a big slice of Monday doing viva voce examinations of selected candidates; not just those on borderlines, but also some others for “calibration”. I wasn’t involved in them this year, but have taken part in the past as External in various places. Obviously these examinations are very stressful for the students, and also quite difficult to conduct fairly, but sometimes provide useful insights in the cases where a student’s marks put them on a knife-edge between two degree classifications (or even between pass and fail).

Anyway, in its infinite wisdom Cardiff University has decided to scrap the viva voce examination after next year. From 2014 onwards we’ll just have to apply a formula to deal with borderline cases; the algorithm involves counting how many modules were passed at the higher level, etc. Actually, I probably agree with this for the purposes of classifying degrees. Twenty minutes’ questioning under stress can hardly be expected to yield much objective  information about a candidate’s knowledge of the subject that dozens of written papers and other assessments. Often, in my experience, students (especially the shy ones) are so nervous that the shutters come down almost straight away.  I would  prefer a system which is algorithmic as possible, so everyone knows what the rules are, rather than relying on subjective judgements.

As external, I always found the viva examinations a useful way of getting feedback from the students on their course which can be fed back – either usefully or not – to the department. In losing the viva  for drawing up the classification lists, I hope that we can find another way for the externals to talk to students in some other context to get some feedback about the course. Perhaps they could attend for project talks, or something like that?

Yesterday, the entire Board of Examiners (including Externals) gathered to go through all the individual cases and draw up the Honours List. I was delighted when I saw all the consolidated marks in advance of the meeting, to see how well how many of our students had done. There were one or two difficult cases, but in the end we produce the lists. As I went back to my office, students were already gathering in the corridor by the noticeboard where it is always placed as soon as the definitive final version has been prepared, shortly after the meeting closed.

Soon I heard whoops of joy and laughter and had a quick look to see the students congratulating one another. As always on such occasions, I was tempted to go along and chat to a few of them but, as always, I resisted doing so. It’s a time for them, the students, not us, the staff.

Anyway, congratulations to all those who had good news yesterday!

I hope your hangovers aren’t too bad…

49 not out

Posted in Biographical, Finance, Politics with tags , , on June 5, 2012 by telescoper

Yesterday having been my birthday – which Her Majesty The Queen kindly declared to be a national holiday – I am now just a year short of a half-century. HMQ has decreed that today is also a national holiday, thus giving me the chance to get rid of my hangover before returning to work a year older on Wednesday.

Fortunately I didn’t have to endure the Queen’s Official party at Buckingham Palace on TV  last night, and instead went to see the fabulous Lady Boys of Bangkok who are in Cardiff all week as part of their UK Tour. They perform in the purpose-built mobile Sabai Pavilion which for this week is situated in Cardiff Bay. Not only did I enjoy the show, I also escaped being hauled up on stage and turned into part of the act. Other members of the audience weren’t so fortunate…

I suspect most of the audience there were also celebrating birthdays or other special occasions, but some were probably just trying to escape from the all-encompassing Jubilee celebrations, of which I’m sure I’m not alone in being completely bored.  So bored, in fact, that I can’t even be bothered to go into the whole Monarchist versus Republican thing.

Still, at least I wasn’t forced to work as an unpaid steward at the stupid river pageant on Sunday, and required to sleep rough under London Bridge, under threat of losing my benefits. Slavery is another fine British tradition.

I think the people who focus on getting rid of the  Monarchy are misguided. Of course it’s an undemocratic and anachronistic institution, but it only has a symbolic status; it doesn’t have any actual power. The real threat to democracy is not the Royal Family, but the rampant capitalism that taken the world’s financial systems to the brink of chaos. Only when we’ve come up with a sensible plan for the world economy in the post-capitalist era – which, in my view, is approaching rapidly – will it be worth making the effort to remove some of the tattered decorations left behind by the old system.

The ongoing financial crisis gripping the world’s economy only exists because governments were persuaded of the need to use taxpayers’ money to underwrite losses in the banking sector. Bankers like capitalism when it comes to making profits, but are happy to fall back on socialism when they make a mess. Now the bankers’ losses have turned into a crippling burden of sovereign debt that could take decades to pay off. And who profits from this? The people who made the mess in the first place.

There is an obvious solution to this problem. A one-off tax of 20% of the accumulated wealth  of the top 10% of the population would raise a staggering £800 billion for the Treasury. This option isn’t even discussed in Parliament because our politicians know their masters wouldn’t like it. And so we go on squeezing ordinary folk and letting the rich off the hook. I don’t think this can go on forever without someone figuring out that we’ve been royally had.

The Train and the River

Posted in Biographical, Books, Talks and Reviews with tags , , , on May 12, 2012 by telescoper

Well, here I am back in Cardiff after my little trip to Merseyside. The weather behaved itself and so did the trains in both directions, so it was quite a pleasant travelling experience. In fact, going there yesterday I managed to make a technically impossible connection at Crewe, owing to the train from Cardiff being a minute or two early and the train to Liverpool being a minute late.

I stayed last night at the Jury’s Inn at Albert Dock, shown on the left here. There’s a sort of Ferris Wheel thing next to it. These contraptions seem to be popping up all over the place. Next thing you know there’ll be one in London! The hotel was of its type, generic but reasonably comfortable. Brings back memories of STFC panel meeting; the Jury’s Inn there is a standard place to stay in Swindon when sentenced to hard labour. Unfortunately the one I stayed in was booked up by multiple stag and hen parties and was ridiculously noisy all night. I didn’t really get any sleep until well after 4am. Grump.

Anyway, last night we had a very nice dinner at the Clove Hitch restaurant/bistro (which I definitely recommend) preceded by a pint at the famous Philharmonic Pub. Thanks to Phil and Sue for looking after us so nicely.

My talk opened the proceedings at the Merseyside Astronomy Day, which was held at Spaceport on the Birkenhead side of the Mersey. Here’s a view of Liverpool’s impressive skyline taken from there, with a nice sailing barge on the Mersey.

The small auditorium – usually used for Planetarium shows – was pretty full and I think my talk went quite well, although it’s not really for me to say. They did actually record everything so if I can get hold of a copy I might post it. Anyway, after my turn there was a fascinating lecture by Prof. Peter Read of Oxford University about the atmospheres of Jupiter and Saturn.

After a quick lunch we used Liverpool’s excellent public transport to zip back to Liverpool Lime Street and I had a relaxing and punctual journey back to Cardiff, albeit with no miracle change at Crewe this time. Dozing on the train I quite startled to wake up near Shrewsbury to find a vintage steam locomotive in sight:

No doubt there’ll be someone out there in internetshire who will tell me all about this train through the comments box but for now I’m going to make some dinner and take it easy as I’m rather knackered.

COBE and after…

Posted in Biographical, The Universe and Stuff with tags , , , on April 24, 2012 by telescoper

An item on the BBC website yesterday reminds me that it is twenty years since the announcement, in April 1992, of the discovery of temperature variations across the sky in the cosmic microwave background radiation by the Cosmic Background Explorer (COBE). Was it really so long ago?

At the time the announcement was made as I actually in the USA. In fact,  I was at the University of Kansas for about a month working on this paper with Adrian Melott and Sergei Shandarin, which eventually came out early in 1993. I remember it very well because we started the project, did all the calculations and wrote up the paper within the short time I was there. Oh what it is to be a postdoc, having only research to think about and none of the other distractions that come with more senior positions.

Anyway, the COBE announcement hit the news while I was there and it got a lot of press coverage. I even did a TV interview myself, for a local cable news channel. Nor surprisingly, they were pretty clueless about the physics of the cosmic microwave background; what had drawn them to the story was George Smoot’s comment that seeing the pattern of fluctuations was “like seeing the face of God”. They were disappointed when I answered their questions about God with “I don’t know, I’m an atheist”.

The Face of God?

I didn’t know at the time that the way the announcement of the COBE discovery was handled had caused such ructions. Apparently George Smoot let his enthusiasm get the better of him, broke ranks with the rest of the COBE team, and did his own press conference which led to accusations that he was trying to steal the limelight and a big falling-out between Smoot and other members of the team, especially John Mather. It’s unfortunate that this cast a shadow over what was undoubtedly one of the most important science discoveries of the twentieth century. Without COBE there would have been no WMAP and no Planck, and our understanding of the early Universe and the formation of galaxies and large-scale structure would still be in the dark ages.

As a lowly postdoc at the time, living a hand-to-mouth existence on short-term contracts, I didn’t realise that I would still be working in cosmology twenty years later, let alone become a Professor.  Nor could I have predicted how much cosmology would change over the next two decades. Most of all, though, I never even imagined that I’d find myself travelling to Stockholm as a guest of the Nobel Foundation to attend the ceremony and banquet at which the 2006 Nobel Prize for Physics was awarded to George Smoot and John Mather for the COBE discovery. It was a wonderful one-in-a-lifetime experience, made all the nicer because Smoot and Mather seemed to have made peace at last.

Where were you when the COBE results came out?

Welcome to Britain

Posted in Biographical with tags , , , , on April 17, 2012 by telescoper

Well then. Back to Blighty. Not the  best journey home, though.

For a start, the 11-hour flight from Cape Town became a 12-hour  flight because of an hour spent circling around in a holding pattern over South London. One expects that at Heathrow. Air traffic delays are the rule rather than the exception, and you learn to get used to it. Kind of. Although since it always happens you would think the airlines might include it in their timetables and other advertising, for the sake of honest and accuracy. Just saying. Nevertheless, this didn’t particularly annoy me.  Despite  getting no more than an hour’s sleep last night I was in a fairly good mood when I got off the plane.

At least until I got into the terminal building, Terminal 5 at Heathrow. For those of you not familiar with this terminal, it’s a gleaming and apparently spacious affair only a few years old. The problem is that when it gets busy, like this morning, you discover that this glitzy exterior masks a design that’s completely idiotic.

We landed at a `B’ gate on a satellite building connected to the main terminal via a `transit’, i.e. a small train. A very small train. When passengers from my flight got to the concourse from which the transit departs, it was crammed full of people who had to squeeze onto the the little train when it eventually arrived:

All this for a journey of about 2 minutes. It would have been much simpler to have constructed a walkway to the main terminal. In fact there is one. For staff only. But not for the passengers. There had to be a transit. Transits are the thing. Of course having a transit means having an extra subterranean level to the building, with lifts going down to it at one end and up from it at another. But lifts are the thing also. There are lots of lifts at Terminal 5. Going forward we’ll all be going up and down.

I wonder if the architect had shares in a company that makes lifts and transit trains?

Anyway on arrival at Terminal 5 there was a similar scrum at the lifts up to passport control. No escalators were working, so I had to wait in the crowd of disgruntled passengers, gradually inching forwards while the 3 operating lifts came and went. As we went up it dawned on me that there might be a delay at passport control..

In fact there were delays before we even got there. The immigration hall was so full that we had to form three separate queues along a corridor just to get into the main queue.

When I finally got into the immigration hall, it was pandemonium. The capacity in this area is clearly far too small and there are far too few people checking passports. The system just can’t cope with the traffic being sent through it. It’s a basic management problem that apparently nobody is prepared to do anything about. Improving it would cost money, of course, but why bother? Passengers are hardly going to turn around and go home at that point, so who cares?

At least the queue for UK/EU passport holders was moving. As I inched forward through the rat’s maze towards a desk I looked from time to time at the “Other passports” line, which barely budged. I felt a sense of anger mixed with shame. What sort of message does this send to visitors to our shores? What kind of country is it that makes showy new buildings like Terminal 5 and then runs them like Fawlty Towers?

They don’t allow photography in the passport control area, by the way. The ban is no doubt an attempt to conceal the evidence of what a shambles it is.

Anyway, at least the long delay at Immigration meant that my bag had arrived at the Baggage Reclaim by the time I got through. I picked it up and made for the Heathrow Express connection to Paddington. The time was just after 8.30; one hour and three quarters after we’d landed.

Still at least I was on my way. Or was I? The train departed and then stopped at a signal. We waited. Eventually the driver explained that there was a major points and signal failure so only one line was operating. We got to Paddington, but it took 35 minutes rather than the usual 15.

There is an alternative way of getting back to Cardiff from Heathrow, which involves taking a bus to Reading and getting the train from there. Although that route is cheaper, there is a risk of severe traffic delays at rush-hour periods, so opted for the Heathrow Express in the belief it was more reliable. More fool me.

When I arrived at Paddington, it too was a mass of disgruntled people. The reason? No trains.

The same signalling problem was disrupting trains into and out of Paddington. All departing trains were simply marked as “delayed” on the boards. Eventually, I got the 9.15, which departed at 9.38. Not too bad in the end. Except that it had to navigate a crowded route westwards. We arrived at Reading after 50 minutes instead of the usual 25.

Then things seem to settle down. We started to move at full speed. I even had a short nap. I was woken by an announcement from the guard. It had been decided that the train I was on would not, after all, be going to Cardiff but would terminate at Newport. First Great Western like to make the most of any possible inconvenience. It’s only 15 minutes from Newport to Cardiff, but it was too much trouble to take us that short distance. We were turfed off and had to wait for local commuter train. Not surprisingly, it was packed so I had to stand all the way.

I’ll be expecting a refund from First Great Western, but that’s not the point. It’s their contemptuous attitude to the travelling public that’s the point. Their prices are so high one might expect them to treat passengers with some respect. But no.

Anyway, I got home exhausted, stressed and frustrated. Given how badly things had gone I half-expected my house to have fallen down while I was away, but thankfully all was well back at the ranch. I decided to cool off a bit before writing this account of the journey, otherwise it would have been even more intemperate! I had been planning to go into work this afternoon but was in no fit state.

Still, it’s good to be home. Kind of.

It ain’t half hot…

Posted in Biographical on April 13, 2012 by telescoper

Just to point out that it’s over 30 degrees today. I realised it was going to be a scorcher, at least by my standards, when I emerged from the underpass on my way to the department and felt the full heat of the Sun. And that was at 9am.

I’m not very well adapted for high temperatures, unlike the people who live here. The other day I heard a student complaining about how cold it was, only 24 degrees. When I said that it wasn’t really that cold in Cape Town, as London was only 12 degrees on that day, he said he couldn’t understand how people could live in a place where there was only half as much heat….

I do hope it wasn’t a physics student.

The World as a Beach

Posted in Biographical, The Universe and Stuff with tags , , , , , , on April 10, 2012 by telescoper

Well, as some of you will have noticed, I’ve been offline over the long weekend. There’s no internet connection – not one that I could get to work, anyway – at the residence I’m staying in and I couldn’t be bothered to traipse all the way up the hill to the department in the pouring rain to connect from my office. Hence the first gap in my postings this year. I don’t suppose anyone minds that much. Anyway, here are a few pictures and random thoughts from the weekend.

Here’s a picture of the residence, by the way. It’s called Kopano, although when I previously stayed it was called Driekoppen. The old name was a relic of the days of slavery – three slaves were tortured and executedin public  after rebelling against the terrible conditions they were held in. Their heads were displayed on pikes nearby, hence the name which means “Three Heads”. This was in 1724. I’m not surprised that the end of apartheid brought a change in the name, although keeping it as it was would have served as a reminder of South Africa’s terrible past. One shouldn’t  become obsessed by events that took place such a long time ago, but neither should one forget them.

Good Friday was a very Good Friday indeed, starting with a lovely breakfast and a walk on the beach in Muizenberg. Apparently this is something of a surfer’s paradise but, as I said, I didn’t have an internet connection so couldn’t join in. Also, they have sharks here. I mean big ones. Great White ones, as  a matter of fact. None showed up while I was there, though, and in any case I was only paddling along the shoreline. It may not be obvious from the picture, but it was pretty hot. Almost 30 degrees.

 I was watching a chap surfing while we walked along and it reminded me of the post I did a while ago about teaching analogies. Standing on a beach looking out towards the horizon is a bit like doing cosmology. Off in the far distance everything looks smooth; the waves on the surface are much lower in amplitude than the depth of the sea out there, so everything evolves linearly and is quite easy to understand. That’s like looking back in time at the early Universe imprinted on the cosmic microwave background. Nearer to the shore, however, the waves become non-linear because their height is comparable to, or larger than, the depth of the water. These waves evolve in a non-linear way producing, breaking on the beach to produce foam and spray, just as the primordial waves collapse to form galaxies and the foam of large-scale structure when their self-gravity becomes sufficiently strong.

That’s enough of that, I think.

Unfortunately, the weather changed for the worse over the rest of the Easter weekend and torrential rain kept me from doing much on Saturday or Sunday. The finishing section of the  Two Oceans Marathon, which ended on the UCT campus on Saturday, was like a quagmire. As you can see from the picture, I reached the line well in front of the pack. About two days in front, actually. I took this as they were building the stands and hospitality tents a few days before the race.

Anyway, the good side of the bad weather was that I got quite a lot of work done, catching up on things I have let slip for far too long. I also exhausted the reading material I brough with me, so will have to find a good bookshop in the next day or two. Well, that’s about enough for now. I hope to continue regular dispatches from now on until I return to Blighty  next week.

Cape Town Connections

Posted in Biographical, Books, Talks and Reviews on April 4, 2012 by telescoper

Now I’m properly online and reconnected to the blogosphere. The problems I had yesterday turned out to be quite easy to resolve once I spoke to a competent person.

I’m staying here on the delightful campus of the University of Cape Town, where I’m visiting George Ellis and other cosmologists here with a view to setting up a collaborative project with them. The last time I was here was in 1995, and I came here to put the finishing touches to a book George and I wrote. At that time I don’t think there was much of an internet connection at all, so I had no distractions from the task in hand. Except, that is, for the Rugby World Cup which took place in South Africa at the same time. Which was not, if I’m being honest, a coincidence. I even managed to get a ticket for the semi-final between England and New Zealand which was held just down the road at Newlands and saw Jonah Lomu running amok as England got thrashed. New Zealand went on to lose to hosts South Africa in a tense final and the celebrations afterwards were something I’ll remember for a long time!

That was all during June/July, which is winter time here. Now it’s April. Technically speaking this is autumn, but the weather is sunny and warm although there are stiff breezes and scudding clouds. Not unusually, Table Mountain is wearing a white fluffy crown, as you can see from this picture I took this morning from the base of the stairs leading up towards the Jameson Memorial Hall and, to the right, the Mathematics department at UCT:

I realised yesterday that I’m staying in exactly the same flat (one of five at the UCT residence called Kopano), a short walk down the hill (or a long walk up it) from the guest office they’ve provided. When I started to walk up yesterday morning the memory of the route came back, apart from one or two new buildings which have inconveniently appeared on the way. I’m reassured that I still have some functioning memory cells!

Another connection I have with Cape Town is that my former PhD student Rockhee Sung has a PDRA position here. I’m looking forward to catching up with her again, although she’s not here at the moment owing to here having to sort out some problems with visas, etc.

Anyway, I have to give a talk tomorrow and since I’m going out for dinner tonight I had better prepare it this afternoon.

P.S. My commiserations to those of you back in Blighty who are shivering as the recent warm spell has been decisively ended by a cold snap, complete with snow. It seems I left at exactly the right time!

 

Web Life

Pure vanity drove me to post this screenshot of a nice write-up of this blog that appears in this month’s Physics World. You can read the whole edition online here if you have a subscription, but if you click on the image it’s more-or-less legible. They’ve written very nice things about In the Dark,  so hope I don’t get into trouble with their copyright enforcers by posting this…

End of Term

Posted in Biographical, Education with tags , , , on March 30, 2012 by telescoper

So here we are, then. The last day of term has finally arrived.  Many of our students will be out partying tonight before they start a three-week break with little to disturb their relaxation but project reports, assignments and examination revision. Probably not all that relaxing at all then, especially for the final-year students.

For various reasons I’ve found this term very heavy going and am  looking forward to spending some time away over the next couple of weeks.  More about that in due course, assuming I have internet access…

The curious thing about the academic year is that since most UK universities switched to a semester system we’ve had to cope with the fact that Easter isn’t on a fixed calendar date. Last year, Easter was rather late so we managed to squeeze in a full 11 weeks teaching in before the vacation started. This year we’ve only got time for 9 weeks, so we resume teaching in three weeks’ time for another two weeks, followed by a revision week and the examination period. I think most students probably agree with me that this hiatus is extremely annoying.

This year Good Friday is on 6th April (a week today) and Easter Monday on 9th April; both are statutory (“bank”) holidays in the UK. Most universities have felt obliged to move their recess so that these two holidays occur outside term-time.

If I had my way we would have fixed semester dates so this nonsense of a 9+2 week teaching semester wouldn’t happen. Last year’s 11-week uninterrupted run was a slog, but I much prefer it over the stop-start affair we’re having this year.

I was a visiting professor at an American university over one Easter period many years ago. Given the fact that the Christian lobby is far more powerful over there than it is here I was quite surprised by the fact that there’s no real interruption for Easter. Lectures were held on Good Friday and there’s no Easter Monday holiday. Easter Sunday was definitely observed, but that had no effect on teaching.

The two Bank Holidays are a bit of a problem, of course, especially because they are followed by two more in May. However, when I was an undergraduate at Cambridge, we had lectures as normal on bank holidays.  I’m not sure whether that practice was restricted to Oxbridge colleges – where term dates are different to elsewhere anyway – or some other Universities did the same. I don’t even know if Oxbridge still carries on over bank holidays today…

A better solution would be to distribute the statutory holidays more evenly through the year so they weren’t concentrated so inconveniently in Spring. There would be  nothing to stop Christians taking a day’s leave in order to observe Good Friday, of course.

But since only a minority of British people are practising Christians, why are the rest of us forced to arrange our calendars according to archaic and irrelevant rituals?  Far better, in my opinion,  to give us all a day off for the start of the cricket season…

Grumble over, it just remains for me to wish my loyal readers (Sid and Doris Bonkers) all the best for the recess, and I hope it’s a good night at the Student Ball tonight!
