The Great Escape

Posted in Cricket, Uncategorized with tags , , on July 12, 2009 by telescoper

Just a little postscript to my blog post about the cricket at Cardiff. After Australia ran away to 674-6 and had England at 20-2 last night before the rain came down after the tea interval, it looked odds-on for an Australian victory. That impression was strengthened by the feeble batting of  England’s leading batsmen this morning. The rain that had been forecast also failed to materialize, so  England were staring at defeat with the score at 70-5 at one stage.

This afternoon one England batsman, Paul Collingwood, did show some mettle and the tailenders who had played brightly on Day 2 demonstrated much greater resilience than their teammates had this morning. Nevertheless, when Collingwood was out later on, it still looked like Australia would win. Eventually it came down to the last pair, the bowlers Monty Panesar and James Anderson, to cling on, bat out time and attempt to salvage an unlikely draw from almost certain defeat. Monty in particular defended like his soul depended on it and together the two tail-enders saw England to safety. Great stuff.

I absolutely love it when things like this happen. There’s something very “Dad’s Army” about bowlers having to save the day with the bat. Backs to the wall and all that. I have to admit I was completely gripped by the drama of the last hour or so of play and so nervous I was shaking as I watched. One mistake and the match would be lost. Runs didn’t matter, just survival. Fielders all around the bat. The crowd applauding every delivery that was kept out. Only cricket can produce that stomach-churning intensity. At the end of the time allocated for play, England were 252-9, just 13 runs ahead. Australia just hadn’t managed to get that last one out. The defiant rearguard action had held off everything that was thrown at them. England may have needed two innings to reach the score that Australia obtained in one, but that doesn’t matter. Match drawn.

If you want to know how a game can go on for five days and still end in a draw, this is how. And bloody marvellous it is too!

England have their work cut out to improve enough to compete over the rest of the five-match series for the Ashes, but at least this escape has denied the Australians the massive psychological boost the expected  big victory would have given them. I know it’s a draw, but there’s no doubting which team will be happier tonight.

And I’m really happy that the First Ashes Test at Cardiff turned out to be such a memorable one!

Advanced Fellowships

Posted in Science Politics with tags , , , on July 11, 2009 by telescoper

This is just a quick Newsflash that UK Astronomers will be  interested in (and depressed by). My attention was drawn to it yesterday by Frazer Pearce of Nottingham.

The Science and Technology Facilities Council (STFC) has decided in its finite wisdom to cut in half the number of Advanced Fellowships (AFs) it awards each year, that is from 12 to 6, that number to cover all of Astronomy and Particle Physics.

These fellowships are awarded to researchers who do not have a permanent position but wish to pursue research, and are designed to further the careers of individuals with outstanding potential. They last 5 years – longer than the usual 2-3 year postdoctoral positions and have been for many a scientist an important stepping-stone to an academic career. A very large fraction of my colleagues who have permanent positions were awarded one of these fellowships when they were run by PPARC (including Frazer), as was I myself but, being an Oldie, mine was even pre-PPARC so was in fact given by SERC. Of course the fact that they gave me one doesn’t itself serve as much of a recommendation for continuing them, but it is worth drawing attention to the huge amount of  high quality research done in the UK by holders of these Fellowships.

A number of people have expressed to me their shock at this decision but it doesn’t surprise me at all. For one thing, it’s an open secret that STFC considers the academic community in these areas to be too large so the last thing it wants is more people getting permanent jobs through the AF route.  In any case, STFC’s prime concern is with facilities, not with scientific research.

Who needs half a dozen top class scientists when you can have Moonlite instead?

Ashes Ground

Posted in Cricket, Uncategorized with tags , , on July 11, 2009 by telescoper

Any of you who follow cricket will know that this is a very special time for the game and for the city of Cardiff. The First Test in the summer’s Ashes series against Australia is being played here. It’s the first time a test match has ever been played in Cardiff’s splendid ground at Sophia Gardens and to have an Ashes test as the inaugural fixture is a tremendous boost for the city. It’s actually a very good venue for Test cricket, being so close to the city centre and I hope this will be the first of many matches to be played here in Cardiff.

Owing to my general state of disorganization I didn’t manage to get a ticket when they first went on sale. Thinking I’d missed out I agreed to go and give a talk in Cambridge on the first day of the Test (Wednesday 8th July 2009). However,  a second load of tickets went on sale  a few weeks ago and I manage to get a couple for Thursday’s play (9th July). I was joined for the day by my regular contributor and old friend Anton.

The SWALEC stadium at Sophia Gardens, Cardiff (left) is actually just a short walk from my house in Pontcanna. The daily crowd of around 15,000 has caused a bit of congestion in the area but we got to our seats without any bother at all.

 

It’s actually quite a small ground, and our seats were right at the front of the Really Welsh Pavilion (which is the far side of the ground as seen in the picture), so we were close to where the players emerged onto the field. The outfield was extremely green with fairly lush grass on it and weather quite nice, with a mixture of broken cloud and sunshine.

England had won the toss and batted first on Wednesday, picking two spinners (Swann and Panesar), presumably in the belief that this was a slow wicket that would be increasingly helpful to the spinners as time wore on and the pitch began to break up a little. After some alarms and rash shots, and the unfortunate loss of two wickets right at the end of the day, England had batted their way to 336 for the loss of 7 wickets.

There having been no track record of Test cricket at Cardiff it was difficult to know whether this was a reasonable score or not. I had been away all day on Wednesday so hadn’t seen any of the play. By all accounts the pitch had played rather slow but was otherwise fairly good for batting. All England’s specialist batsmen were out so it wasn’t clear what kind of total they would reach with their remaining three wickets, but the tail wagged quite enjoyably and they added another 99 runs in the morning session until Swann ran out of partners and was left unbeaten on 47 with a little time to go before lunch.

So far, so good from an England point of view. However, from the point of view of their chances of winning the game it all started to go wrong as soon as the Ozzies went in to bat. The openers scored quite freely off the first few overs from England’s bowlers and went into lunch at 39-0.

For the rest  rest of the day, the England bowlers struggled to make any impression at all on the skilful and determined Australian batsmen. Flintoff accounted for the opener Hughes during a hostile spell of bowling in which he regularly exceed 90 mph and also dropped a very difficult caught-and-bowled chance. However, that only brought the Australian captain, Ricky Ponting, into bat which he did quite beautifully. He made no mistakes at all in his innings and played no rash shots, but by the end of play both he and Katich had reached centuries and Australia were 249-1.

Apart from Hughes’ wicket and Flintoff’s dropped return chance the only other time England were close to nabbing a wicket was a shout for LBW from Swann which was close but, I thought,  a bit high. Swann bowled very economically but without any real danger. Panesar was unimpressive, as where the other England seamers Broad and Anderson. It wasn’t that they bowled badly or were wayward, it just seemed that there was nothing in the pitch to help them and, of course, they were up against extremely good batting.

I wouldn’t say that this was the best day’s cricket I’ve ever seen – not by a long way – and I know that it’s a game that’s too slow for the taste of a lot of people anyway. There were, however, times – especially when Flintoff was bowling – where the atmosphere turned into something that you only get in cricket. As he pounded in over afer over with very few runs being scored and the batsmen defending stoutly, the action on the field became just the surface manifestation of a deep inner struggle between batsmen and bowler.  Who would win this battle of wills? The  stress could be felt all round the ground and one sensed that whoever came through that passage of play would have scored an important psychological victory. Undoubtedly the Australians came out of it stronger for having weathered everything England could throw at them. I find this kind of attritional cricket absolutely absorbing to watch, but I know many people who don’t get it.

Later on, after the match,  the England pace bowlers expressed their mystification that the ball simply wouldn’t swing. I was surprised too. I have no idea of the physics behind what makes a cricket ball swing but, empirically, it seems to correlate with the presence of cloud and humidity in the air. Both of these were present on Thursday but at no point did the ball curve, even for Anderson who is an accomplished swing bowler. This probably accounted for the ease with which the England tail had batted earlier in the morning.

Anyway, although I would definitely have preferred to see England skittle out the Australians, I did at least have the chance to watch a master batsman at work. I have to say I found it fascinating. Although there wasn’t a great deal of strokeplay – they didn’t really dominate the bowling – they ground their way to centuries in a very resolute fashion. There were very few boundaries scored, partly because of the very slow outfield.

Another reason I enjoyed the day was that our block of seats had its own resident comedian, a character called Chris who was found of shouting comments not only about the cricket but to anyone having the nerve to come into the stand during play.

Early on in the day this chap sitting behind us decided to amuse the crowd by shouting out clues from the Times crossword to see if anyone could get them. I got the first one straight away (the answer was METHODIST: IST was German for “is” and “Method” was clued by a reference to Stanislawski but I don’t remember the clue exactly).  Like a fool, shouted the answer back to him. I  became a target for him for the rest of the day’s play.

After several hours of his banter, I have to admit being a bit fed up with him but at least the crossword clues were fun.I don’t remember many of  them, but did get “Car held at murder location” (CATHEDRAL, i.e. anagram of car held at and reference to Murder in the Cathedral by TS Eliot) and “Rehabilitation of ailing animal” (NILGAI, anagram of ailing, is an Indian antelope). Eventually he came down, gave me the newspaper, and challenged me to finish the whole thing. I did so, and sent it back through the crowd, even getting a round of applause from them as I did so. I had become a minor celebrity providing a bit of distraction from Australia’s success. We may not have been doing well in the cricket, but at least I wasn’t letting the side down when it came to crosswords. Chris argued for a bit with some of my answers – he didn’t think TSETSE was a word, for example – but I think I convinced him I was right.

When play finished shortly after 6pm we left the ground to walk into town for something to eat. The path to the little bridge over the Taff was very crowded. Australian and England supporters mingled and, at one point, someone behind me shouted “Hey look, it’s Peter the crossword guy!”. Fame at last.

I didn’t have tickets for Friday but set out for work rather late. As I walked down Cathedral Road, crowds were turning up for Day 3. I nearly died when someone across the road shouted “Peter! Done the crossword yet?” I was quite impressed to be remembered, but hope my new found celebrity status disappears as quickly as it arose.

POSTSCRIPT: Australia batted throughout Day 3 to pass England’s total of 435 all out and had reached 479-5 despite losing some time to rain. The forecast for today (Saturday) was for rain, but it has so far refused to materialize and the Ozzies have powered on to 577-5 at lunch. It’s now a game that England can’t win. It is very overcast and still looks like some time will be lost to rain, so a draw is the likeliest result as long as England don’t fold pathetically in their second innings. Not that they haven’t done that before…

Sensational SPIRE

Posted in The Universe and Stuff with tags , on July 10, 2009 by telescoper

As I promised a few days ago, the “first light” images from the Herschel instrumment SPIRE have now been released (along with news of the other instruments on Herschel)  and I have to say they’re pretty spectacular! I’m told that these pictures are much better than anyone expected at this stage because Herschel as a whole still hasn’t finished its calibration and other preparations it needs to do before commencing as an observatory proper.

Here, for example, is an image of the spiral galaxy M74 (also known as NGC 628) as shown by SPIRE and by the American Spitzer satellite, which was launched a few years ago. This image is taken at 250 microns, which is further into the infrared than the Spitzer image (160 microns), but has higher resolution owing to Herschel’s bigger mirror (3.5m). The SPIRE instrument is also much more sensitive than Spitzer so by a combination of these effects the detail this image reveals is really stunning.

What you’re actually seeing in this image is long-wavelength radiation emitted by dust which has been heated up by stars in the galaxy. The dust obscures the optical light from the stars but they leave clues to their existence in the infrared light the dust gives off. You can see dark lanes in the optical image here where the dust is absorbing the starlight.

Here is M74 again, but shown with two additional infrared “colours” (at 350 and 500 microns). By making observations like this at different wavelengths SPIRE can reveal information about the spectrum and hence temperature of the dust emission.

Congratulations to the Cardiff SPIRE team for a stunning success. If these images are any guide to the quality of data Herschel is going to be producing over the next few years then we’re all in for a treat!

Why the Big Bang is Wrong…

Posted in Biographical, The Universe and Stuff with tags , , on July 7, 2009 by telescoper

I suspect that I’m not the only physicist who has a filing cabinet filled with unsolicited correspondence from people with wacky views on everything from UFOs to Dark Matter. Being a cosmologist, I probably get more of this stuff than those working in less speculative branches of physics. Because I’ve written a few things that appeared in the public domain (and even appeared on TV and radio a few times), I probably even get more than most cosmologists (except the really  famous ones of course).

I would estimate that I get two or three items of correspondence of this kind per week. Many “alternative” cosmologists have now discovered email, but there are still a lot who send their ideas through regular post. In fact, whenever I get a envelope with an address on it that has been typed by an old-fashioned typewriter it’s usually a dead giveaway that it’s going to be one of  those. Sometimes they are just letters (typed or handwritten), but sometimes they are complete manuscripts often with wonderfully batty illustrations. I have one in front of me now called Dark Matter, The Great Pyramid and the Theory of Crystal Healing. I might even go so far as to call that one bogus. I have an entire filing cabinet in my office at work filled with things like it. I could make a fortune if I set up a journal for these people. Alarmingly, electrical engineers figure prominently in my files. They seem particularly keen to explain why Einstein was wrong…

I never reply, of course. I don’t have time, for one thing.  I’m also doubtful whether there’s anything useful to be gained by trying to engage in a scientific argument with people whose grip on the basic concepts is so tenuous (as perhaps it is on reality). Even if they have some scientific training, their knowledge and understanding of physics is usually pretty poor.

I should explain that, whenever I can, if someone writes or emails with a genuine question about physics or astronomy – which often happens – I always reply. I think that’s a responsibility for anyone who gets taxpayers’ money. However, I don’t reply to letters that are confrontational or aggressive or which imply that modern science is some sort of conspiracy to conceal the real truth.

One particular correspondent started writing to me after the publication of my little book, Cosmology: A Very Short Introduction. I won’t gave his name, but he was an individual who had some scientific training (not an electrical engineer, I hasten to add). This chap sent a terse letter to me pointing out that the Big Bang theory was obviously completely wrong.  The reason was  obvious to anyone who understood thermodynamics. He had spent a lifetime designing high-quality refrigeration equipment  and therefore knew what he was talking about (or so he said).

His point was that, according to  the Big Bang theory, the Universe cools as it expands. Its current temperature is about 3 Kelvin (-270 Celsius or therabouts) but it is now expanding. Turning the clock back gives a Universe that was hotter when it was younger. He thought this was all wrong.

The argument is false, my correspondent asserted, because the Universe – by definition –  hasn’t got any surroundings and therefore isn’t expanding into anything. Since it isn’t pushing against anything it can’t do any work. The internal energy of the gas must therefore remain constant and since the internal energy of an ideal gas is only a function of its temperature, the expansion of the Universe must therefore be at a constant temperature (i.e. isothermal, rather than adiabatic, as in the Big Bang theory). He backed up his argument with bona fide experimental results on the free expansion of gases.

I didn’t reply and filed the letter away. Another came, and I did likewise. Increasingly overcome by some form of apoplexy his letters got ruder and ruder, eventually blaming me for the decline of the British education system and demanding that I be fired from my job. Finally, he wrote to the President of the Royal Society demanding that I be “struck off” – not that I’ve ever been “struck on” – and forbidden (on grounds of incompetence) ever to teach thermodynamics in a University.

Actually, I’ve never taught thermodynamics in any University anyway, but I’ve kept the letter (which was cc-ed to me) in case I am ever asked. It’s much better than a sick note….

This is a good example of a little knowledge being a dangerous thing. My correspondent clearly knew something about thermodynamics. But, obviously, I don’t agree with him that the Big Bang is wrong.

Although I never actually replied to this question myself, I thought it might be fun to turn this into a little competition, so here’s a challenge for you: provide the clearest and most succint explanation of why the temperature of the expanding Universe does fall with time, despite what my correspondent thought.

News from L2

Posted in The Universe and Stuff with tags , on July 6, 2009 by telescoper

Just a quick update with a couple of bits of news about Planck.

First, the satellite has completed its final  manoeuvre and is now in its orbit around the second lagrange point. The  orbit is, in fact, slightly smaller than was originally planned owing to the fact that the extreme accuracy of the post-launch trajectory left a bit of extra fuel. Anyway, it’s now about 1.5 million kilometres from home, circling L2 which is what it will be doing for about a year.

The second bit of news has been the cause of particular celebration here at Cardiff. The High Frequency Instrument (HFI) has been cooling down since launch and has now reached its operating temperature of 0.1K (100 milliKelvin). The environment it is sitting in is about 60-70K so it’s no easy job to get it down to such a low level. Anyway, it’s now definitely the coolest thing in space…

The Cardiff HFI team celebrated on Friday, with beer that was no doubt suitably chilled.

Planck spins at about 1 revolution per minute and has been sending back scans of the sky for test purposes.  The HFI scans show that it is working well, detecting dust emission from the Galactic Plane well before it got down to sufficiently low temperatures to see the cosmic microwave background.

What happens next is the Calibration and Performance Verification phase during which the instruments will be checked out in great detail before the real science gets started in August.

Space Camp

Posted in Uncategorized with tags , , , , , on July 4, 2009 by telescoper

The other day I was looking through my copy of the Men’s Disciplinary Rubberwear Gazette (which I buy for the Spot-the-Ball competition). Turning to the advertisements, I discovered that the Science & Technology Facilities Council is conducting a review of its space facilities and operations. Always eager to push back the frontiers of science, I hurried down to their address in Swindon to find out what was going on.

ME: Hello. Is there anyone there?

JULIAN: Oh hello. My name’s Julian, and this is my friend Sandy.

SANDY: Oooh hello! What can we do for you?

ME: Hello to you both. Is this Polaris House?

JULIAN: Not quite. Since we took over we changed the name…

ME: To?

SANDY: It’s now called Polari House…

JULIAN: On account of that’s the only language spoken around here.

ME: So you’re in charge of the British Space Programme then?

JULIAN:  Yes, owing to the budget, the national handbag isn’t as full as it used to be so now it’s just me and her.

SANDY: But never fear we’re both dab hands with thrusters.

JULIAN: Our motto is “You can vada about in any band, with a satellite run  by Jules and…

SANDY: …Sand.

ME: I heard that you’re looking for some input.

SANDY: Ooooh. He’s bold, in’e?

ME: I mean for your consultation exercise…

JULIAN: Oh yes. I forgot about that. Well I’m sure we’d welcome your contribution any time, ducky.

ME: Well I was wondering what you could tell me about Moonlite?

SANDY: You’ve come to the right place. She had an experience by Moonlight, didn’t you Jules?

JULIAN: Yes. Up the Acropolis…

ME: I mean the Space Mission “Moonlite”

SANDY: Oh, of course. Well, it’s only small but it’s very stimulating.

JULIAN: Hmmm.

SANDY: Yes. It gets blasted off into space and whooshes off to the Moon…

JULIAN: …the backside thereof…

SANDY: ..and when it gets there it shoves these probes in to see what happens.

ME: Why?

SANDY: Why not?

ME: Seems a bit pointless to me.

JULIAN: There’s no pleasing some people is there?

ME: Haven’t you got anything more impressive?

SANDY: Like what?

ME:  Maybe something that goes a bit further out? Mars, perhaps?

JULIAN: Well the French have this plan to send some great butch omi to troll around on Mars but we haven’t got the metzas so we have to satisfy ourselves with something a bit more bijou…

SANDY: Hmm…You can say that again.

JULIAN: You don’t have to be big to be bona.

SANDY: Anyway, we had our shot at Mars and it went willets up.

ME: Oh yes, I remember that thing named after a dog.

JULIAN: That’s right. Poodle.

ME: Do you think a man will ever get as far as Uranus?

JULIAN&SANDY: Oooh! Bold!

SANDY: Well I’ll tell you what. I’ll show you something that can vada out to the very edge of the Universe!

ME: That sounds exciting.

JULIAN: I’ll try to get it up right now.

ME: Well…er…

JULIAN: I mean on the computer

ME: I say, that’s an impressive piece of equipment

JULIAN: Thank you

SANDY: Oh don’t encourage her…

ME: I meant the computer.

JULIAN: Yes, it’s a 14″ console.

SANDY:  And, believe me, 14 inches will console anyone!

JULIAN; There you are. Look at that.

ME: It looks very impressive. What is it?

SANDY: This is an experiment designed to charper for the heat of the Big Bang.

JULIAN. Ooer.

SANDY: The Americans launched WMAP and the Europeans had PLANCK. We’ve merged the two ideas and have called it ….PLMAP.

ME: Wouldn’t it have been better if you’d made the name the other way around? On second thoughts maybe not..

JULIAN: It’s a little down-market but we have high hopes.

SANDY: Yes, Planck had two instruments called HFI and LFI. We couldn’t afford two so we made do with one.

JULIAN: It’s called MFI. That’s why it’s a bit naff.

ME: I see. What are these two round things either side?

SANDY: They’re the bolometers…

ME: What is this this long thing in between pointing up? And why is it leaning to one side?

SANDY: Well that’s not unusual in my experience …

JULIAN:  Shush. It’s an off-axis Gregorian telescope if you must know.

ME: And what about this round the back?

SANDY: That’s your actual dish. It’s very receptive, if you know what I mean.

ME: So what does it all do?

JULIAN: It’s designed to make a map of what George Smoot called “The Eek of God”. It’s fabulosa…

SANDY: Or it would be if someone hadn’t neglected to read the small print.

ME: Why? Is there are problem?

JULIAN: Well, frankly, yes. We ran out of money.

SANDY: It was only when we got it out the box we realised.

ME: What?

JULIAN & SANDY: Batteries Not Included!

(With thanks to cosmic variance for the inspiration, and apologies to Barry Took and Marty Feldman, who wrote the original Julian and Sandy sketches for the radio show Round the Horne.)

Slippage and Slideage

Posted in Science Politics with tags , on July 3, 2009 by telescoper

Back from the week’s exertions I’ve just realised that I missed the announcement from the Science and Technology Facilities Council (STFC) of the changes to their programme as a result of the 2009 budget settlement.

You can find the full statement here, but of immediate concern to astronomers is the plan to cut funding for the Cambridge Astronomical Survey Unit (CASU) and the Wide-Field Astronomy Unit (WFAU) at Edinburgh. I’m not sure how much their support is to be reduced and what the long-term implications of the cuts will be.

Expenditure on the outrageously useless space gizmo Moonlite will be delayed until next year, thus saving another bit of money. In my opinion, it would have been better simply to have cancelled this one altogether and diverted the funding into research grants which are instead to be held at the levels they were cut to last year.

Other savings will be made by “rephasing” (i.e. delaying) other projects in particle and nuclear physics and some others have started late anyway for other reasons.

Any optimism there might have been about a better settlement at the next Comprehensive Spending Review has now totally evaporated, however, and I wouldn’t bet against STFC having to cope with further large cuts  (in cash terms) a few years down the line. There are several ongoing consultation exercises (see Andy’s discussion and my earlier post for details) which will no doubt be used to draw up hit lists that will be used to make further cuts if and when needed.

The immediate impact of this review exercise on the astronomy programme seems considerably less brutal than I feared, but what may be going on is simply a holding operation and that the really drastic decisions will happen later, after money has already been spent on projects that are really already doomed. Still, a stay of execution is better than immediate termination.

Hot in Town

Posted in Science Politics, The Universe and Stuff with tags , , on July 2, 2009 by telescoper

After a fun but frantic few days in the big city I’ve now escaped back to the relative cool of Cardiff. The Royal Society Summer Science Exhibition appears to be going very well, but my part in it has come to an end. The rest of the team will have the joy of continuing for the rest of the week and then dismantling the exhibit and returning with it at the weekend.

The exhibition proper started on Tuesday and our stand was drawing a lot of visitors right from the word go. That’s partly because we had a very good spot, right near the entrance, but we also had a bit of  coverage on the BBC News which might have helped. Inside the building we attracted quite a lot of people to our stand because we were showing infrared images on a large flatscreen monitor of people as they walked past. That seemed to draw people in large numbers to the other parts of the exhibit which was, after all, the purpose of it.

People look quite strange in the infra-red. Here’s an example:

photo_2

That’s me. The calibration scale to the right is in Celsius: hot is white (37) or yellow and cold is blue or black (26). Red is in the middle, around 30 Celsius. Different people seem to have different hot spots and cold spots: most  appear to have cooler ears and lips compared to the rest of their faces, but noses vary considerably in temperature.

There was only one potentially embarrassing moment, when a group of teenage lads wandered in front of the camera. Apparently, a certain type of mens’ underwear has very high emissivity around 10 microns. I just happened to glance up at the monitor and noticed a prominent hotspot just in time to tilt the camera up before anyone else noticed. Thereafter we kept it focussed above waist level just in case…

After my shift on Tuesday I had to nip back on the tube to my temporary lodgings, shower, change into my dinner jacket and black tie, and then return to the Royal Society for the much-anticipated Soirée. Taking the tube turned out to be a mistake. The heatwave currently gripping London has turned the underground system into something resembling the inside of an oven, so I decided to walk back rather than melt again when I’d got changed. I drew a few strange looks walking through Soho in my glad rags, but at least it was cooler at street level than on the Underground.

The evening occasion  turned out to be very busy too. To my surprise, it wasn’t just champagne and posh nibbles: a substantial meal was on offer in a marquee at the back of the Royal Society building. However, there were large crowds moving through the exhibition and we only had six people on the exhibit. We therefore staggered our trips to the grub tent making sure there was always someone at the exhibit to deal with the invited guests. By the time my turn came round it was 9.30 and the whole thing closed at 10.00. I still had time for a good nosh-up and a couple of glasses of wine, though, so all was well.

At the exhibit there was a steady supply of champagne and VIP guests. Lots of Lords and Ladies and other bigwigs,  but I hadn’t the faintest idea who most of them were. These are all the kind of people who assume that everyone on the planet (a) knows who they are and (b) is impressed to have the opportunity to meet them. Being surrounded by such a sea of effortless superiority is quite intimidating but, fortunately, there were also some familiar faces who stopped by and appeared interested. The noted biologist Steve Jones dropped by, and had his picture taken in the infrared, as did John Polkinghorne. I had met Polkinghorne before not long ago, but he clearly didn’t remember me at all.

“Medals may be worn” was one of the instructions, but I had neglected to bring  my cycling proficiency badge.

Summer Science

Posted in The Universe and Stuff with tags , , on June 29, 2009 by telescoper

Just time for a very quick post today, owing to the hectic nature of the past (and future) few days.

Yesterday (Sunday) morning, I clambered on board a large van full of expensive and bulky gear and we lumbered away from Cardiff, down the M4 and all the way to London. The reason is the Royal Society Summer Science Exhibition, which involves various research groups setting up exhibits and demonstrating their wares to the general public in the splendid environs of the Royal Society building in Carlton House Terrace, just off Pall Mall.

Yesterday and today we’ve been setting up our exhibit, which is about Herschel and Planck  (both of which are still working perfectly, in case you wanted to ask). Unloading the van in the sweltering heat yesterday wasn’t that much fun but everyone was very helpful and we got through it.  We had temporary flooring to put down, lots of rigging and large flat monitors needed to be hoisted on to gantries. I felt a bit like a sort of up-market roadie. Most of the heavy work was done yesterday, though, and we spent today putting the computers and other electronic exhibits together and generally making it all work. I chipped in as best I could, despite my legendary incompetence with practical things. They didn’t really let me near anything really valuable anyway.

By about 2pm today we had finished, and I have to say it looks very impressive. Credit to Chris North, and the others who spent ages designing it and organizing the logistics of what is a very complicated exhibit. There are scale models of Planck and Herschel, and a full-size model of the instrument SPIRE which is on Herschel and which was designed and built by the Cardiff team. The complexity of the optical system is quite amazing. Incidentally, I heard a rumour that some test images from SPIRE are going to be released soon.. I hear they’re stunning. Watch this space.

As well as these other bits there’s an infrared camera attached to a monitor to show your hot bits, and another monitor with a wii attachment so you can see anywhere on the sky at any wavelength you wish. There are also two touch-screen displays that can take visitors through the science and technology behind these two wonderful  satellites.  It’s all very interactive, and I think it’s going to be a hit for the hands-on visitors.

To back this all up, we’ve also got mountains of leaflets, mugs, pens and other assorted memorabilia. I think they’ve overestimated how much of this stuff we can dispense in a week, but I’m sure it will come in handy in the future anyway.

An extensive rota has been organized to set the exhibit up and  keep it staffed. I had an all-day shift yesterday and was signed up for 8-3 today. Since we actually got everything done a bit early, however, I was given permission to leave. At 3pm today there was a “press preview” of the exhibition which I could’t stay for, so I figured I might as well leave before the reptiles started to arrive.

I’ll be on the stand tomorrow, trying to be nice to the public, and back again on Wednesday doing the same. The shifts are only 4 hours at a go, which is good because it’s quite tiring keeping up the enthusiasm. It’s also forecast to be extremely hot on the weather front which is another reason to keep the shifts short. I was longing for a beer by the time I finished yesterday.

I’ve also been invited to a “soirée” on Wednesday evening, which is a swanky black tie function at which sundry VIPs view the exhibits and chat with the exhibitors over champagne and canapés. ‘m quite looking forward to the chance to indulge myself and hang out with the big nobs, but I can’t say I’m looking forward to wearing the penguin suit when it’s 30C. Still, as long as the champagne is chilled I’m sure I’ll survive.

Toodle pip.
