Posted in Biographical, Education with tags Cambridge, Magdalene College on March 22, 2013 by telescoperDuring my short visit to Cambridge on Wednesday I happened to pass through Magdalene College (on my way to a couple of pints in The Pickerel). I couldn’t resist taking a pic of the Lutyens Building, where I lived in the first year (1982/3). My room was second from the far end, on the first floor. I wonder who’s in there now?

Posted in Art, Biographical, Cosmic Anomalies, Open Access, The Universe and Stuff with tags Axis of Evil, Cambridge, Cavendish Laboratory, Cold Spot, Cosmic Microwave Background, Planck, Pointillism on March 21, 2013 by telescoperThe reason I was out of the office yesterday was that I was in Cambridge, doing a PhD oral in the Cavendish Laboratory so the first thing to say is congratulations Dr Johnston! It was one of those viva voce examinations that turned out to be less of an examination than an interesting chat about physics. In fact the internal examiner, Prof. Steve Gull, seemed to spend more time asking me questions rather than the candidate!
Afterwards I met up with Anthony Lasenby, the candidate’s supervisor. Not surprisingly the main topic of our brief discussion was today’s impending announcement of results from Planck. Anthony is one of the folks who have been involved with Planck for about twenty years, since it began as a twinkle in the eye of COBRAS/SAMBA. I was looking forward to getting in bright and early this morning to watch the live streaming of the Planck press conference from Paris.
Unfortunately however, I could feel a bit of a lurgy coming on as I travelled to Cambridge yesterday. It got decidedly worse on the way home – it must have been the Cambridge air – and I even ended up passing out on the train from Victoria to Brighton. Fortunately, Brighton was the terminus so someone woke me up when we got there and I got home, coughing and spluttering. I suspect many cosmologists didn’t sleep well last night because of excitement about the Planck results, but in my case it was something else that kept me awake. Anyway, I didn’t make it in this morning so had to follow the announcements via Twitter. Fortunately there’s a lot of press coverage too; see the ESA site and a nice piece by the BBC’s redoubtable Jonathan Amos.
Anyway, without further ado, here’s Planck’s map of the cosmic microwave background:
It’s rather beautiful, in a pointillist kind of way, I think…
It will take me a while in my weakened state to complete a detailed study of the results – and I’m sure to return to them many times in the future, but I will make a couple of points now.
The first is that the papers and data products are all immediately available online. The papers will all appear on the arXiv. Open Access sceptics please take note!
The second is that the most interesting result (as far as I’m concerned) is that at least some of the cosmic anomalies I’ve blogged about in the past, such as the Axle of Elvis Axis of Evil and the famous colder-than-it-should-be cold spot, are still present in the Planck data:
The other results excite me less because, at a quick reading, they all seem to be consistent with the standard cosmological model. Of course, the north-south asymmetry is a small effect on could turn out to be a foreground (e.g. zodiacal emission) or an artefact of the scanning strategy. But if it isn’t a systematic it could be very important. I suspect there’ll be a rush of papers about this before long!
I’m sure to p0st much more about the Planck results in due course, but I think I’ll leave it there for now. Please feel free to post comments and reactions through the box below.

Posted in Biographical, Rugby with tags Chaos Society Ball on March 17, 2013 by telescoperI’ve been offline for a couple of days owing to being back at the old place in Cardiff, and consequently without internet connection. I could have used my phone, of course, as I’m doing now, but the 3G coverage in Wales is very poor so I find it frustrating to blog on my Blackberry.
Anyway, I came back to Cardiff to take care of a few loose ends and also to attend the annual Chaos Ball on Friday evening, which is run by the staff-student society in the School of Physics & Astronomy. It was a pleasant experience to see former colleagues and students again, so thanks to the organisers for finding tickets for me and my guest at the last minute!
Yesterday it was a different ball that took centre stage, as this year’s Six Nations rugby came to a dramatic conclusion with Wales’ comprehensive and well-deserved victory over England in Cardiff. I didn’t go to the game, but did watch it in a local pub. There’s a very special buzz in Cardiff on such occasions, and I was glad to experience it one more time, despite being an Englishman..
Now I have to get my act together and head back to Brighton. I wonder what sort of balls the British railway system will serve up?

Posted in Biographical with tags Brighton, Snow, University of Sussex on March 12, 2013 by telescoperThe last twenty-four hours in Brighton have been very strange. It started snowing yesterday morning. Not snowing very much, actually, but it was also very cold so not a very pleasant way to start the week. Nevertheless I had a trouble-free bus trip to the University of Sussex campus and got on with my business. It carried on snowing a bit, but not much. This is what it looked like outside my office at about 11.30.
It kept on snowing a bit, but not much, all afternoon. By five o’clock I noticed that the Twitter feed for the Brighton & Hove Bus and Coach Company was announcing that some bus services were suspended. Then all of its bendy buses were withdrawn from service. Since most of the buses I get to and from campus are of the bendy variety I decided to head home. It was snowing a little heavier by then, and it took a long time to get home owing to heavy traffic, but I made it to my flat by about 6.30pm. Checking Twitter again I saw that all bus servives had been cancelled. The accumulated amount of snow in central Brighton was no more than a centimetre.
Buses remained suspended this morning. Owing to the transport difficulties facing its staff and students the University of Sussex decided to cancel teaching for the day and operate at a minimal level of service. I settled down to work a bit at home, with a view to travelling to campus as soon as the buses were running again. In fact the roads appeared very clear when I decided to make the most of my morning off, by doing some shopping and getting a haircut, but the bus service to Falmer was not reinstated until about two hours after I took this picture…
When I did eventually get on a Number 25 bus, the roads were completely clear of snow. Not surprisingly, actually, because although it snowed for quite a long time it was really rather light.
What is staggering is that less than half an inch of snow could paralyse the transport system of entire Town the size of Brighton, especially when it was forecast days in advance. There may have been heavier snowfall elsewhere in the area of course. The town is also rather hilly which, in icy conditions could cause problems for buses. But Brighton & Hove Council’s preparations for this cold snap seem to have been woefully ineffective. It’s sobering to experience how vulnerable this town is to even slightly bad weather.
Anyway, I’m now on campus. It’s not snowing. The sun’s shining, in fact. All the roads are clear. But there are few students about because there’s no teaching going on. Time to get some work done…
..and then try to get home!

Posted in Biographical, Education, The Universe and Stuff with tags Phd Interviews, School of Mathematical and Physical Sciences, University of Sussex on March 2, 2013 by telescoperWell, although it seems like no time at all it appears I’ve now been in Brighton and working at the University of Sussex for a whole month! Here’s a picture of the street I live in in the Kemptown area of Brighton, taken this afternoon. That’s the English Channel at the end of the road, in case you don’t know where Brighton is; it’s definitely not in the Midlands.
I’m currently on campus again, although I made a major miscalculation in that Brighton and Hove Albion are playing at home again today. Since the Amex Stadium is just over the road from the University, that means I’ll either have to go back before the final whistle blows or wait until the crowds have dispersed before returning to base.
It has been unbelievably hectic. Although I knew it was going to be hard work taking over as Head of School halfway through the academic year, several unforeseen things have come up that have made me even busier than I’d anticipated. Some of these were pleasant surprises and some weren’t, but that’s all I’m going to say for now!
Since I arrived a large part of my time has been spent on matters relating to new staff appointments, arising from a mixture of replacements and new investment across the whole School of Mathematical and Physical Sciences. That has included new staff in Applied Mathematics, Theoretical Particle Physics, Experimental Particle Physics, Atomic, Molecular and Optical Physics and of course Astronomy. There are more to come over the next few weeks, including a new group in the area of Probability and Statistics. It’s pleasant work, of course, especially when it goes well (which it definitely is) but I have to admit that the schedule of presentations and interviews is rather exhausting.
Apart from that the other principle preoccupation has been strategic planning for the next five years. On Thursday morning I had a crunch meeting with members of the University’s management team to discuss the plans for MPS, which were actually drafted before I took up my post but have since been modified quite a bit. I was more nervous before that meeting than I’ve been for many years, primarily because I did not know what to expect. It turned out to be quite pleasant, actually, and I left the meeting not only relieved but relaxed.
In the afternoon it was back to interviewing, but this time for postgraduate students. That’s also a pleasant duty, because it involves giving excellent young scientists their first step on the ladder towards a research career. I’m sure it’s not so pleasant for the candidates though. Nerves sometimes get the better of the students in these interviews, but experienced interviewers can calibrate for that. And if you’re nervous, it means that you care…
Anyone reading this who is nervous about doing a PhD interview (or has experienced nerves in one they’ve already had) might reflect on my experience when I was called to interview for a PhD place in Astronomy at the University of Manchester way back in 1985. I was very nervous before that, and arrived very early for my grilling. I was told to wait in a sort of ante-room as the previous interview had only just started. I started to read a textbook I had brought with me. About five minutes later, the door of the interview room opened and the interviewers, Franz Kahn and John Dyson, carried out the unconscious body of the previous candidate. It turned out that, after a couple of friendly preliminary questions, the two Professors had handed the candidate a piece of chalk and told him to go to the blackboard to work something out, at which point said candidate had fainted. When it was my turn to be handed the chalk I toyed with the idea of staging a mock swoon, but resisted the temptation.
The question, in case you’re interested, was to estimate the angle through which light is deflected by the Sun’s gravity. I hadn’t done any general relativity in my undergraduate degree, so just did it by dimensional analysis. That seemed to go down well and they offered me a place … which I turned down in favour of Sussex.

Posted in Biographical, Education with tags Brighton, Brighton and Hove Bus, Falmer, Margaret Thatcher, University of Sussex on February 27, 2013 by telescoperOne of the things I’ve had to get used to about working at a University based on an out-of-town campus is that it’s no longer feasible to walk to work every morning. Fortunately there is an excellent bus service from central Brighton to Falmer, so this isn’t too much of a hardship. I’ve now invested in one of those new-fangled smart cards that makes it very economical not only for getting to work, but also for hopping on and off while pottering about town doing shopping and whatnot.
I have noticed that if I get the No. 25 bus from Old Steine before 8am it only takes about fifteen minutes to get to the University of Sussex. If I’m a bit late starting out, however, and don’t get to the bus stop until after eight in the morning, the trip can take about forty minutes. The problem is that roadworks on the A27 Lewes Road have reduced it to a single lane in each direction; there’s a critical point when the traffic builds up to rush hour levels and then solidifies. Still, I don’t mind getting in before 9am as that gives me useful time before the roll of meetings commences, so I found it quite easy to adapt to the early start.
Anyway sitting on the bus this morning I had a kind of flashback to my schooldays. The school I went to was on the opposite side of Newcastle to where I lived, so I had to take the bus every morning. I did much the same thing in those days as I am doing now, in fact – getting the bus at 7.30 to avoid the heaviest traffic, and often doing the previous night’s homework before lessons started in the morning.
The one thing that was very different in those days (and we’re talking about the Seventies now) was that the “School Run” didn’t really exist. Even the posh kids took the bus or train to School rather than being ferried back and forth by doting parents. I think it did me a lot of good travelling on the bus along with all kinds of other people rather than being transported in the hermetically sealed cocoon of a family car. The famous friendliness of Tyneside folk undoubtedly contributed to the omnibus experience and left me with a lifelong preference for public over private transport. I’ve never owned a car and have no intention of ever doing so.
Anyway, this all reminds me of the (probably apocryphal) quote from Margaret Thatcher:
A man who, beyond the age of 26, finds himself on a bus can count himself as a failure.
Whilst I’d by no means be ashamed to be counted a failure according to a Thatcherite criterion, I did once get a bit riled by a version of it when I was conducting a UCAS Admissions Day at another institution (also a campus university). A (male) parent of one of the candidates asked me why there was so little car parking space for students on the campus. I replied that undergraduates were basically not allowed to park on the campus, otherwise it would be overrun with motor vehicles and wouldn’t be so nice and spacious and green. However, I said, that’s not a problem because there was an excellent bus service that could take students to the University from town and vice versa in just a few minutes. The indignant father bristled and announced in a very loud and angry voice “No son of mine is going to get on a bus”. That was the nearest I’ve ever come to losing my temper with a parent on a university admissions day. Fortunately nothing like it has happened since.
It never would have occurred to my parents to come with me when I visited universities for interview and I would have been horrified if they had insisted on doing so. Nowadays, however, prospective students are invariably accompanied by parents, who generally ask at least as many questions as their offspring do. Is this just an extension of the School Run, or is because parents now have to foot the bill (when in my day there were maintenance grants and no tuition fees). Either way, times have definitely changed.
Anyway, I’m about to get the bus home. Tomorrow we are interviewing prospective postgraduate (PhD) students. I don’t think any will bring their parents along. And quite a few may even come on the bus.

Posted in Biographical, The Universe and Stuff with tags Cosmic Microwave Background, Cosmology, Planck on February 21, 2013 by telescoperA very busy day interviewing candidates for a job in Experimental Particle Physics was made even busier by the arrival by the boxes containing all my books and other knick-knacks from Cardiff. Anyway, the net result of all this is that I only have time for a brief post before I go home and lapse into a coma. I can at least do something useful, however, which is to pass on the following announcement:
Presentation of the first cosmologic results of Planck mission as well as its first all-sky images of the Cosmic Microwave Background
Launched in 2009, Planck studies the Cosmic Microwave Background – the relic radiation from the Big Bang – to allow cosmologists to zero-in on theories that describe the Universe’s birth and evolution. The first all-sky images of the Cosmic Microwave Background will be presented at the press conference held in Paris ESA HQ on March 21st, 2013.
We’ve been expecting that the “cosmologic” results from Planck would be announced sometime early this year. Now we know when. March 21st 2013 is the date to put in your diary, and that’s only about a month from now. Exciting times.
Will Planck confirm the standard cosmological model and measure its parameters more precisely? Or will there be the first hints of physics outside the standard model? Will cosmology be all done and dusted, or will we find out that we didn’t understand the Universe as well as we originally thought?
I don’t know. Yet.
Follow @telescoperTwo cultures, or none?
Posted in Art, Biographical, Education with tags C.P. Snow, Two Cultures, Universities on February 14, 2013 by telescoperJust a quick rehash of an old post by way of a follow-up to Sunday’s blog about Emotion and Creativity which touched on the negative stereotypes sometimes used to characterize scientists.
Anti-science attitudes are far from unusual among the Arts & Humanities fraternity, even in the supposedly enlightened environment of a University, which I think is a real shame. After all, you’ll have to work very hard to find a scientist who would be prepared to stand up in front of audience and proudly announce “I hate art”. Many of my scientific colleagues have deep passions for the performing arts (especially music and drama) as well as being very well read across a wide range of subjects. Many also hold strong (and often idiosyncratic) political opinions and are involved in a huge range of activities outside science.
In short, scientists don’t just sit in their labs and offices making dangerous chemicals or torturing small animals. We live in the real world and have as much contact with wider society as anyone else. Imagination, creativity and free thinking can be found in scientists, just as they can in the arts. Scientists both contribute to and participate in our society’s cultural heritage. Scientists are human beings. Culture belongs to us too.
Some time ago there was an article in the Times Higher with the title “Life depends on science but the arts make it worth living“. I agree with a lot of what is written in the piece, in fact, although it does seem also to contain numerous examples of non sequitur and I think it’s both poorly argued and highly exaggerated. The arts are undoubtedly among the things that make life worth living, but there are others, such as “ordinary” human relationships and the “simple” enjoyment of the natural world, which academics of all persuasions all too frequently neglect.
One of the most prominent examples of non sequitur in the Times Higher article is that we have music, literature, poetry and the rest but how much of this is actually done in universities? The article compares Einstein with Beethoven. Albert went to University in Zurich. Beethoven didn’t go to a university. There’s a big difference between making art and writing about it. One of the big cultural differences between art and science is that we don’t have science critics, although we do have people who popularize it and also people who try to explain it to the general public. Much of the impenetrable cultural analysis that emerges from academia concerning the arts seems to have the opposite aim. Does any university have a Professor of the Public Understanding of Art?
You probably think I’m going to go off on a rant about the famous Two Cultures thesis advanced by C.P. Snow, but I’m not. I think Snow’s analysis is only marginally relevant. I do think that there are “two cultures”, but these are not “science” and “the arts”. One is a creative, thinking culture that encompasses arts, the humanities and science. The other is its antithesis, a “culture” that sees the sole function of education as being to train people to take their place on the never-ending treadmill of production and consumption.
The way we are heading, it’s not “two cultures” that we should be worried about. It’s no culture at all.

Posted in Biographical, Music with tags Arvo Pärt, Piano, Spiegel im Spiegel, Violin on February 11, 2013 by telescoperI’ve been so busy this last week that I really needed to unwind a bit on Sunday morning, for which purpose I picked this beautifully spare and sublimely contemplative piece by the great Estonian composer Arvo Pärt. This music always makes me think of the first line of the Desiderata…
Go placidly amidst the noise and haste, and remember what peace there may be in silence
..except of course that it’s not silent.
