Transi(en)ts in transit

Greetings from London, and the latest entry in my (increasingly maritime themed!) blog.  I'm in transit to Washington DC for the 2nd USA National Science and Engineering Festival, where I'll be part of the team representing the Laser Interferometer Gravitational Observatory (why not follow us on tiwtter - @LIGO) with our travelling gravitational-wave astronomy exhibit - or at least parts of it; we didn't fancy this time spending 3 hours assembling and dis-assembling it, as we had to do at the first Festival in October 2010.  One new addition we have for the exhibit this year is a pop-up stand, which is basically a giant version of the LIGO bookmarks designed by Brooke Rankin for the 2009 and 2010 World Science Festival:

I've been in London since Monday for a 2-day discussion meeting at the Royal Society on New Windows on Transients Across the Universe.  By "transients" we generally mean anything that goes "bang" over a short time - things like exploding stars (supernovae) or gamma-ray bursts, at least some types of which could be major sources of gravitational waves that we hope to detect in the not-too distant future.  It was a very good meeting, with lots of interesting projects either going on already or planned for the next 10 - 20 years.  The meeting is being followed by a more specialist workshop at the Kavli Royal Society International Centre in Buckinghamshire (close to Milton Keynes).  So by going to DC I miss out on a visit to Milton Keynes, but speaking as someone who grew up in East Kilbride (aka Polo Mint City) I can live with that.

While in transit in London, however, I was delighted to get the chance to give a talk on the forthcoming Transit of Venus at the Royal Observatory Greenwich.  Given the history of ROG in connection with earlier transits, and the great quest to measure accurately the size of the Solar System, it was an honour to give a talk on the subject. In fact my talk was arranged for the famous Octagon Room, where Astronomers Royal of the past did their stuff:

The ongoing maritime theme comes from the history of Greenwich, its role in the thefascinating story of the Longitude Prize and the proximity of the Observatory to the Cutty Sark and the National Maritime Museum.  Getting to Greenwich these days is also probably easiest by boat, so by late afternoon Tuesday I had taken myself down to the Embankment (pausing en route only to note that, according to the clock in Trafalgar Square, it was 94 days, 4 hrs, 38 mins and 27 secs until the start of the Olympics)

and caught a Thames Clipper service along to Greenwich Pier.  The trip along was filled with impressive sights (even if not quite a patch on the Hebrides!) including the London Eye, Tower Bridge, the Cutty Sark and lots more.

Once up at the Observatory I had a wee while to admire the view over the City, and the Millennium Dome with the Olympic Park nestling behind, before it was time to head up to the Octagon Room.

There I was met by my host Sara, who runs the public programmes at the ROG and National Maritime Museum.  The Octagon Room was just as I’d remembered it from previous visits and it was nicely set up for my talk.

The only problem was the bright sunshine shining through the windows!  After working out the best place to put the screen, to allow for the Sun moving westwards during my talk (surely a problem an astronomer could solve!) we were all set.

There was a good crowd of about 25 people, including several members of the local Flamsteed Astronomy Society, who told me about their plans to get up early and observe the transit on June 6^th.  I’m hoping we can hook up with them from our all-night event in Glasgow.

After my talk, and some time for questions (some really good ones - the Flamsteed Society really know their stuff), I headed back down to catch the ferry back to central London – and enjoyed some more excellent (if rather blurry in the photos) views of the city skyline.  

Not exactly the dark skies of Tiree,though: the light pollution is pretty appalling, and increasingly so with the addition of more tall buildings such as the (otherwise very impressive) Shard. Makes you realise we have a long way to go before our cities become havens for naked eye astronomy, although to be fair as I walked back along the Mall and past Buckingham Palace you could see the Moon and Venus (although not a lot else!...)

So now it’s time to set off for Washington and the Science Festival.  More news of the LIGO exhibit from there.

May the force be with you

Exploring the Dark Side of Bute

April 14th 2012 and it was time to head for the islands again!   I'd been asked by Sylvia Jardine, president of the Bute Astronomical Club, to visit the Isle of Bute, in the Firth of Clyde, to help them with an exciting new project they are planning.  Note quite as exciting as my friend and fellow astronomer Steve Owen's expedition (and 6-day ferry journey!) to St Helena, but a nice postscript to my recent Hebridean odyssey.


The Bute Astronomical Club's proposal, being spearheaded together with the Bute Conservation Trust, is to build a Science and Heritage Centre and Observatory, together with an outdoor activity centre, at Meikle Kilmory Farm on the west side of the island.  The land is owned by the Mount Stuart estate, which has a long history of connections with astronomy.

Celestial ceiling in Mount Stuart House, Isle of Bute

Before any of that, however, first of all it was off to Glasgow Airport to collect Prof Joan Centrella, Deputy Head of the Astrophysics Division of NASA Goddard Space Flight Center and world-leading expert on black holes.  Joan is visiting Glasgow and other SUPA institutions for 4 weeks, to give some lectures on numerical relativity - explaining for non-specialists the recent breakthroughs that have allowed us for the first time to model fully the mergers of black holes, which she has pioneered with her collaborator John Baker, and for which they have recently won various awards.

Joan's flight arrived just about on time, so before she could check into her hotel we paid a visit to Offshore on Gibson St, which is currently previewing an exhibition on multimessenger astronomy which I have put together for Glasgow Science Festival 2012.  I'll write much more about the exhibition in a later blog post, and it will soon also have its own dedicated web content, but one of the exhibition images is based on Joan's work simulating black hole mergers, so it was great to let Joan herself preview it in Offshore's basement gallery.

By lunchtime it was off to Wemyss Bay, in time to catch the 1405 ferry to Rothesay.  After all the long ferry journeys of my Island Universe tour for National Science and Engineering Week, the 35 minute crossing to Bute was going to seem exceedingly short, but the weather was good and there was still enough time to capture yet more stunning scenery, looking northwards along Loch Striven.

Sylvia met me at the ferry terminal and we drove over to the far side of the island, and the proposed site which overlooks St Ninian's Bay.   The middle of an April Saturday afternoon isn't perhaps the best time to site test a potential astronomical observatory, but thanks to the wonder of stellarium and my newly installed compass app, I was able to get a good sense of what would be visible and when from the proposed site:

The answer appears to be "a lot"!   The Meikle Kilmory site has a wide open sky, with a very low horizon towards the west and north (looking out towards Arran, the Mull of Kintyre and the hills of Argyll).  The horizon is fairly low in the east and south too - although the hills on that side should do a good job of blocking the streetlights of Rothesay, helping making this a pretty dark site (ok, not as good as Tiree, but then where is?!).  

So all in all it looks like this could be a very good dark sky site.  I look forward to helping bring the plans to fruition - and who knows, hopefully visiting a new observatory on Bute in a couple of years.

Together with the exciting developments at the Galloway Forest Park Dark Sky Observatory, in which I'm also trying to play my part, and of course the existing great observatories, like the Highlands Astronomical Society's JSL Observatory in Culloden, things are really looking up for public astronomy in Scotland!

After a nice meal at the Esplanade Hotel, it was back onto the ferry for the short crossing back to the mainland - with just enough time to catch a shot of the Arran hills and the Ailsa Craig in the distance...

...and to pass the MV Isle of Bute making the return journey in the other direction.

Day 10: The Water of Life

March 20th, and my Island Universe tour is almost over.  Only one more stop, and after all the schools talks I've given discussing the prospects for finding water - and life - elsewhere in the Universe, it seems appropriate (if slightly cheesy) that my final leg takes me to Islay: home of nine distilleries making Scotland's very own water of life.

I set off from Kennacraig on the 7am ferry, and am very struck by both the remoteness of the ferry port (compared with the relative metropolis of Ullapool where my odyssey began) and the impressive new ship I am about to board - the Finlaggan.

Onboard the ship was equally impressive:  spacious and open car deck, modern and comfortable interior fittings, and even free wireless internet!  Having grown quite fond of the "Lord of the Isles", which had transported me reliably to and from the western extremes of the Hebrides last week, this still felt as if I had stepped into the 21st century.  It was also striking to note the dedication plaque on board, however:

which I guess tells its own story about the recent history of shipbuilding on the clyde - although I hear the World's first "hybrid" ferries are currently under construction.

The journey passed quickly and by about 9am we were pulling into Port Askaig, on the Sound of Islay, facing the coast of Jura.

Next it was a short 15 minute drive to Bowmore, on the far side of the island, where Islay High School is situated, immediately adjacent to Bowmore Distillery.  There I met the physics teacher Phil Kitching, who had organised a series of talks with three different groups:  the "certificate class" (Islay HS has small enough numbers that they can teach all the students taking standard grades, highers and advanced highers in Physics together), the second years and the first years.  I covered the (now) familiar ground with these three groups:  a talk on dark matter and dark energy, one on stars and the formation of the chemical elements and one on detecting exoplanets and the search for ET Life.  The third group (the 1st years) were missing their French class to come along and their French teacher came with them too, which gave us a chance to think a little about what language we might use to communicate with any alien lifeforms we might find (although it must be said I don't think it'll be French!).

Over the course of the day I also met with Ian Stuart, Head of Technology and Deputy Head of the High School, and was fascinated to find out more about the school's radical policy on ICT which sees every pupil equipped with a laptop / tablet computer and much of the teaching delivered via wireless intranet.  This really seems to work well and it was very interesting to hear how much the school saves on photocopying costs as a result!

I also had the pleasure of meeting Tristan, one of the 6th year students, who has clearly been doing a lot of reading and thinking of his own.  He had a wide range of questions for me, on everything from neutrino oscillations to majorana particles to the Einstein Field equations.  I did my best to answer them, or at least to give him some more pointers for how to better follow them up.  I was very pleased to hear from Phil later on that Tristan is planning to study physics after he leaves school and I'm hoping that we might see him at Glasgow next year.

After lunch, and a short stroll round the harbour at Bowmore

it was off next to the Bowmore Distillery:

Phil had arranged a tour for us, which seemed a perfect way to round off my trip.   Although I've been on many a distillery tour in my time I always find them interesting, especially with regard to the subtle and important differences in the production methods employed by each company.  In the case of Bowmore they were proud of the fact that they still carry out a lot of their own malting and we were shown around the malting floor to begin with.

During the tour we crossed the courtyard and saw the classic pagoda towers, although one of the chimneys had been blown off during the gales of January 2nd (which brought down some slates from our roof back in Glasgow too).

The tour ended with a visit to the stills themselves

then to the storeroom 

and then back to the visitors centre and a quick dram.  I also had a look in the shop, and found the latest example in my ongoing quest to track down whiskies which are as old as I am.  (Sadly my ability to actually buy these ended many years ago, on the night of my PhD viva when I had a glass of 26 year-old Springbank!)

I then zoomed back to Port Askaig, admiring the Paps of Jura along the way (Phil had told me that he lives on Jura - which has a primary school which his kids go to, but he has to take the ferry across the Sound of Islay back and forth every day).  We got an even better view of the Jura mountains on the ferry (this time the slightly older MV Hebridean Isles) on the way back.

An hour or so later we had passed the Finlaggan on its way back to Islay and we got a wonderful view of it disappearing off into the sunset...

We landed about 7.15pm and I made the short drive back up to Tarbert, where I was stopping off for the night before heading back to Glasgow first thing in the morning.

So my tour was finally over:  27 talks on 9 islands across 9 days (and a few more islands traversed too: North Uist, South Uist, Eriskay...). I'd spoken to nearly 1600 people - aged 4 to 84 - and met some wonderfully dedicated, enthusiastic and talented teachers.  I'd seen some of the darkest skies I've ever witnessed in the northern hemisphere on the far-flung outpost of Tiree.  I'd  also seen some of the most spectacular coastal scenery in the world, right here on our doorstep.    I can't think of a better way to have spent National Science and Engineering Week.  I was reminded of the tales I'd read in my various biographies of his life, of how Albert Einstein had given lecture tours around the world that involved long sea voyages to get him there.  I'd been given a glimpse of that world for myself - in the microcosm of the Scottish islands.  I'm glad to be going home of course but the memories of my Island Universe tour will stay with me for a very long time.

Day 9: Mulling over the Dark Side of the Universe

March 19th dawned wet: a return to the dreich weather of the start of last week.  Time for a quick walk down the hill to Main St Tobermory again, past the distillery...

...and a visit to the bank, before heading off to the High School.  There I met my host Donald Holmes, who had arranged two talks - with Fourth to Sixth years and then with First to Third years - in the Gym.  I got set up fairly quickly, and hooked up to the school's excellent sound system.  I was also able to set up my camcorder to record the first of the talks - on "Putting the Iron in Irn Bru".

Both Mull morning talks seemed to go down well, with lots of good questions from the younger pupils in particular.  I also arranged a visit to the primary school, which is immediately adjacent to the secondary.  We set this up for after lunch, which gave me the time to pop down to the harbour and Main St for some soup and a sandwich at the Tobermory Bakery.

Back at the Primary School for 2pm, I spent the best part of an hour trying to answer a barrage of questions from the pupils!  How wonderfully refreshing to see their enthusiasm and willingness to ask questions, and to demonstrate what they already knew (which was a lot!)   If only I'd had time to visit more primary schools on this trip - but then again Oban High School has about 30 feeder primaries, Iain Fulton told me last Friday, so the logistics would have been way too complicated in other places.

Still the rain was coming down as I drove back to Craignure in time for the 5pm ferry to Oban.  This time it was the "Lord of the Isles", which was fast becoming my home from home...We berthed in Oban about 5.50pm, and I set off for Kennacraig on the Mull of Kintyre.  Not the most pleasant drive of my tour by any stretch, which was a shame because in more pleasant weather the scenery on this leg would have been just as pretty as on the islands themselves - particularly around Ardfern, where I'd been last September for Russell's wedding (but it didn't look quite like this in the March gloom).

Safely ensconsed in Rhu House, just off the A83, by about 8.30pm, I battened down the hatches and got ready for the last leg of my epic journey:  to Islay and Bowmore High School on Tuesday.

Day 8: What's the Story?

Sunday March 18th dawned bright and sunny on Tiree (which is officially the sunniest place in the UK and was living up to its reputation).  After breakfast I packed up the car again and headed for the ferry terminal in good time to catch the 1025 ferry back to Oban.  The crossing was really wonderful, with fantastic views of the islands in the sunshine as we cruised along the Sound of Mull past the lighthouse on Ardmor Point.

Soon we were arriving at Oban again, which even on a Sunday is a bustling town because of the ferry traffic.  As the "Lord of the Isles" pulled into the dock, my next ferry, the "Isle of Mull" was already moored and getting ready for boarding...

...so it was a case of just driving off one boat and almost straight onto another - it felt just like making a flight connection:  I hadn't thought of Oban as the London Heathrow of the high seas!

The crossing to Craignure seemed very short indeed after the long journeys from Barra and to and from Tiree, but there was still time to admire yet more stunning views as we headed out past Kerrera and yet more lighthouses (with yet another striking rainbow in the background).

Sajely landed on Mull I made the short drive to Tobermory, pausing on the way just past Salen for a quick photo of the mainland, looking out towards the Ardnamurchan peninsula.

I finally reached Tobermory (aka Balamory!) about 5.30pm, and after a short stop down on the Main St for the obligatory photograph...

...it was off to my B&B on Breadalbane St, which coincidentally is run by Rebecca MacDonald, maths teacher at Tobermory High School.  Rebecca and Donald Holmes, the physics teacher, had between them come up with a plan for my talks on Monday morning and I gave Donald a quick call to confirm all was well.  Donald suggested that, since the primary school was immediately adjacent to the High School, perhaps I could pay them a visit too.  I figured this would be fine:  my only real constraint on Monday was to catch the 5pm ferry back from Craignure to Oban, to set me up for the last leg of my epic journey, to Islay on Tuesday.

I headed off to An Tobar, the little arts centre where I'd be giving the last of my public talks that evening.

I was a bit unsure of numbers this time, but Rebecca said that she was coming along and expected that a few of her students would be coming too.  In the end there was more than 30 people, which filled the venue, so another big success.   We even managed a little bit of star gazing straight afterwards too - although it was noticeable that the streetlights of Tobermory limited what you could see, even if they were no where near as bad as Glasgow.  (I guess anywhere was going to suffer in comparison with Tiree!)  Unfortunately the clouds rolled in too and we only managed a quick look at Mars and a few other constellations, but there were lots of great questions - particularly from the children.

On the way back to Rebecca's place the clouds suddenly cleared and I got a much better idea of just how dark the skies over Mull could be.  Not having the telescope set up, I was limited to taking a snap of Venus and Jupiter on my phone - but even that was impressive, Venus in particular managing not to be drowned out by the lights of the town.

I was a bit sad that the evening public talks were now over, but looking forward to the final two rounds of schools talks on Monday and Tuesday.

Day 7: The Wee Island

Saturday May 17th: another very early rise to catch the 0645 ferry to Coll and then Tiree.  By 0630 I was back on board the "Lord of the Isles" and settling down for another long journey.

To my great surprise, as I walked into the Observation Lounge on Deck 5 who did I meet but Grant Miller:  former GU Physics and Astronomy student, now PhD student working on exoplanets at St Andrews?!  Grant is someone whose name I've been mentioning frequently on the Island Universe tour so far, particularly in relation to the new Exoplanets Researching Physics topic being introduced in the revised Higher Physics syllabus, and which the pupils in Portree seem to be enjoying so much.  It's a great story to be able to tell the pupils that, less than decade ago, Grant was himself doing the higher - and now he's finding planets himself, as part of the SuperWASP collaboration.  What a pleasant and welcome coincidence to meet him on the ferry.  He told me that he was en route to Coll with some American friends from St Andrews to celebrate St Patrick's Day, staying in the cottage on Coll that belonged to his family (and where his ancestors had once lived). We swapped some stories about what was going on at GU, and how Grant's PhD work was going.  To add to the coincidence, the physics teacher in Tiree is Steven Wilkinson, who had been a Physics and Astro student in the same year as Grant. What are the chances of that?...I got a photo of Grant before they dismebarked at Coll; this will be handy to use in the remaining schools' talks of my tour.

The journey across to Tiree was - if anything - even more jaw-droppingly beautiful than the crossing from Barra to Oban on Friday.  The seas were calm throughout and the sun shone for most of the way - apart from one heavy (and brief) rainstorm as we passed along the Sound of Mull...

...but even that had a silver lining as I managed to get a great photo of a rainbow (with a  strong hint of a second arc) against the backdrop of the Mull hills: this will be great to use in my talks about spectroscopy, and how we use it to detect the "wobble" of stars caused by exoplanets and the redshift of distant galaxies.

We docked in Tiree at about 10.30 and I drove off and headed for the Scarinish Hotel.  

The plan was to meet Steven at about 2pm and then head over to the High School, so this gave me some time to set up the telescope (to save time that night) and get a bit of a walk.  I was also able to watch a little of the Scotland-Italy rugby game, but the less said about that the better...

The bay just in front of the hotel was straight out of a picture postcard...

...and the view from the dunes just beyond the fishing boat was stunning:  i could see Skye, Mull, Staffa, Iona, Jura, and a bunch of smaller islands - including the very distinctive "Dutchman's Cap" which I remembered from our boat trip to Staff from Fionnphort back in 2002.

Steven came by the hotel just after 2pm and we drove off to the School, passing by the airport on the way.  

The afternoon talk was designed for the younger children and we had a great range of ages - from Aidan (who was 4) to Poppy and Iona (who were in early years of Secondary, and so already doing CfE science).  Some of the Mums and Dads stayed too, as did Caroline the Deputy Head. We talked about life in the Solar System and how we find exoplanets (a chance to tell them about meeting Grant!), with a break for drinks and Jaffa Cakes halfway through. I was hugely impressed by the pupils' questions and knowledge and enthusiasm, which I think in no small way is due to Steven's efforts.  I was very pleased to hear from him that there's likely to be a big growth in the number of pupils taking Physics in their 5th year next year.

By about 4.30pm it was time to head back to Scarinish, which we did via the other side of the island, so I could say that I'd circumnavigated it during my brief stay.   The weather was now really beautiful, and from the other side of the island I could see Barra and Eriskay, and maybe a hint of South Uist too, as well as the neighbouring Coll and the small isles Eigg, Muck and Rhum. After a short stop back in my hotel room (enough time to get the Wales-France result; very glad that Wales won the Grand Slam!) and some more photos of the bay...

...it was down to the restaurant to have dinner with Steven and Caroline.  We had a great chat about the pros and cons of teaching in a small school, and about living on small island in general.

At about 7.15pm we headed up to the room where my talk would be given. Already the skies were darkening and there wasn't a cloud in sight, so things were looking very good.  As 7.30pm approached the visitors kept on coming: Steven had to keep going to the bar to get more chairs and the room was getting ever more crowded.  Steven's initial target, that we exceed the number of visitors (nine!) who'd come along for a talk on bugs by a visiting scientist the previous year, had long been surpassed and by the time we got going at 7.45pm there were more than 37 people crammed into the room.

My talk seemed to go down well, despite (or maybe because of) the golden comedy moment when my computer projector decided not to display red colours any more - a bit awkward when you're talking about redshifts!!  We finished up just after 8.30pm and, rather than the usual Q&A session, I suggested that we immediately head for the great (and very dark!) outdoors and take advantage of Tiree's spectacular skies.

And boy were they spectacular.  I explained to the crowd that I hadn't seen anywhere this dark in the UK. There was a tiny hint of light pollution on the horizon from the direction of Tobermory, but otherwise the biggest light pollution was Venus!  This was so incredibly bright that it prevented us from getting a really sharp and clear view of the Pleiades, since otherwise I think I would have had my best chance yet of actually seeing all Seven Sisters (especially armed as I was with my new varifocal glasses).

The only problem was getting the telescope going:  it didn't seem to be finding enough GPS satellites to work out its location and orientation, and given how dark it was I didn't really want to start trying to calibrate it manually.  In truth, however, it was probably better anyway just to show

people what they could see with the naked eye - and since the crowd was so large (most people seemed to have stayed behind after my talk) they wouldn't have got much time looking through the telescope.  Fortunately Steven had brought along a powerful green laser pointer, so I was able to use that to guide people around the sky - showing them all the usual suspects: the different colours of Betelgeuse and Rigel in Orion, the Orion Nebula, the Pleiades and Beehive star clusters, the Andromeda Nebula, Sirius, Gemini, and the planets Venus, Jupiter and Mars.  We also saw loads of satellites passing overhead and a fair number of shooting stars.

We wrapped things up about 10pm, as the cold was starting to seep in, and it was time to retire to the bar. A few hours, and drinks, later I headed off to bed after one of the best dark sky observing sessions I've led in a long time.  Over the course of the day and night I'd talked to about 7% of the island's population, and was delighted that Steven's enthusiasm and persistence in organising these events - and cajoling people to come along - had paid off in such spectacular fashion.

May the force be with you

Day 6: The Big Island

It's Friday March 16th and today I head to the biggest island on my tour: the UK Mainland!  First it's the 5-hour ferry journey from Castlebay to Oban....The ferry is the "Lord of the Isles" and after another early rise I'm all set to board about 0830 when I suddenly remember that I've left my laptop in the hotel.  I haven't done anything that careless for a very long time - but fortunately the situation is easily retrievable and I zoom on foot back up to the hotel to get it and am back in the car before the ferry starts to board......Phew!!!!

The view from the ferry as we travel back to the mainland is quite spectacular, and the weather is very pleasant so I spend most of the time up on deck.  First, there's a close up view of the castle in the bay which gives the town its name.

Then we hit the open sea beyond the bay and there's quite a swell - wouldn't like to make the journey on a stormy day!

The weather stayed fine most of the way across and, after a few hours of seeing nothing but ocean we pass quite close to Coll and Tiree (where I'm headed on Saturday)

We also got more distant views of the small islands Eigg, Muck and Rhum on the other side of the ship.  I was taking the chance on the long sea crossing to catch up on my podcasts, starting with Mark Kermode and Simon Mayo's film reviews from the previous Friday.  Coincidentally, as we were passing Eigg Mark was reviewing the new David Tennant film "The Decoy Bride" which is set on Eigg (or "The edge of Scottish remoteness", as Simon Mayo put it) although apparently it was filmed on the Isle of Man, so maybe the coincidence was somewhat diminished anyway.

By about 12.15pm we were passing the Ardnamurchan peninsula and starting the long, slow sail between the Scottish mainland and the Isle of Mull: wonderful scenery throughout - and a journey I will come to know well as I play my way back and forth along this sound on Saturday and Sunday too.

By 2.15pm we had arrived, after the longest ferry journey I'd ever taken - beating even Napoli to Palermo or Vancouver to Victoria.  In fact it had really felt a bit more like a flight, in terms of its duration and rhythm - although it was nice of course to be able to move around and go up on deck, not really an option at 36,000 feet!

Just like taking a long flight, there was a certain sense of time stopping while on board, so when we did disembark at the Oban Ferry terminal, part of me still thought it was about 0845.  Unlike e.g. a US trip, with the time zone shift, it was already mid-afternoon in Oban so I had to turn my thoughts quite quickly to the evening lecture at Oban High School.

After a quick reviving cup of tea in a coffee shop on the pier front I headed round to my hotel, the Columba Hotel, and checked in, caught up on some emailing and phoned home - and was pleased to learn that Catriona had now seen the unicycling Darth Vader on my blog - and thought it was hilarious!

Soon I was off to the High School, where I met science Faculty Head Iain Fulton, who had kindly given up his Friday evening to organise my talk.  He warned me not to expect quite such big numbers as the BBC One Show was filming in town (to do with the start of Sport Relief) and many of their pupils had been swayed from a talk on the mysteries of the Universe by the prospect of getting a few seconds on TV - a metaphor for our times if ever there were one (although I have a feeling that if I'd been Brian Cox then the odds might have tipped firmly in my favour!)   Despite Iain's caution, there was still a good crowd of more than 20 - making it feel that adding the extra lecture in Oban had been well worthwhile, particularly as we finally got the chance to do a little bit of stargazing afterwards.  The skies were very murky but Venus and Jupiter could be clearly seen in the west when we came out of the lecture, so we had a look at them through binoculars at least and everyone went away happy.  The prospects for much clearer skies (and of course darker skies!) over Tiree on Saturday night are apparently very good so I'm really looking forward to that. Tune in tomorrow to find out how that goes.
