Deep underground, looking outwards.

Deep underground, looking outwards.

Characters in Haruki Murakami’s novels tend to spend a lot of time at the bottom of deep, dark wells or in the depths of forests. After a lot of staring into darkness they usually discover that what they thought was a wall really is in fact a door leading somewhere else. I thought a bit about this the other day when I was at the “Luxembourg” train station here in Paris to see the astronomical images that my friend Mr. Seagull has prepared as part of an underground exhibition which will last six months. (Attentive readers will recognise Mr. Seagull as a regular commentator on this column). Six enormous images have been affixed to the cavernous walls of the Luxembourg metro station, printed out using a special process which can make bright coloured images which can last six months in an environment as hostile as a Parisian metro station where hundreds of thousands of people pass every day.

The images, which are really doors of course, lead further and further out into the Universe, starting out with the rocky Martian landscape seen by the JPL rovers and finishing up with a swathe of the distant Universe as it was seven billion years ago as imaged by the MEGACAM camera on the Canada-France Hawaii Telescope on the island of Hawaii. The image was processed by computers of the TERAPIX project — also underground, in the basement of the IAP. A kilometre or so south of this platform.

Standing next to the images I could see the ancient light dissolve into pixels. I took a few pictures from the other side of the platform. Here is one — but you should go yourself. Or pay careful attention as you pass through the station. Historians of Paris will know that it’s only very recently that one could actually travel through the Luxembourg station. For greater part of the station’s hundred and ten year history it was actually the terminus, the last station on the ligne de Sceaux. That north end of the tunnel was a wall. Now it too leads somewhere else…

leaving Hiroshima and Miyajima

leaving Hiroshima and Miyajima

This time I’m on the misty blue waters of the Inland sea, on a ferry between Hiroshima and Matsuyama. My conference starts tomorrow. To the left and to the right of me are many small forested islands; ahead in the distance on the horizon I can see a vague outline of coastline.

I’ve just spent on day in Hiroshima and one day exploring the Island of Miyajima. Miyajamia is famous for the beautiful red torii of Itsukushima shrine and Hiroshima is famous for — well, you know what Hiroshima is famous for.

I visited the area around the Peace Park, where the monuments and museums are, the afternoon that I arrived from Kanzawa. My hotel’s sole virtue was that it was very close to the Peace Park, but it was a much less interesting place than those “minshuku” that I stayed at in Kanzawa and Nikko.

The museum in the Peace Park documents in a fairly balanced way the events which lead to the atomic bombing of Hiroshima; there were a lot worse things which could be said about why the allies decided to destroy a Japanese city as opposed to a German one which were left unsaid.

The museum has a large collection of artefacts recovered from the city, lunch boxes with the remains of carbonised food inside, watches stopped at the exact instant of the bombing. For each of these items, their story is detailed, the human life that was extinguished with the object. The effects of the bomb were described in unflinching detail. Only five photographs were ever taken in the city on the day of the bombing, I learned, by a journalist who entered the city that afternoon. He could only take those five photographs before he was overcome by emotion and horror, paralysed by the apocalyptic sight before him.

I spent a few hours in the museum, listened to all the audio commentary, looked at all the exhibits. Then I left for the park and walked to the cenotaph in the centre of the park. Standing before the memorial for the victims of the explosion, a curving, undulating arch, one sees in a direct line under the arch the burning flame, the flame that was lit that day in August in 1945, and beyond that charred structure of the “A-bomb dome”, one of the few buildings left standing after the explosion. It was only at that instant that I realised, fully, that those events described in the museum didn’t happen in some abstract place far away. They happened here, on the ground I was standing on.

Some comments I’ve read try to contextualise the deaths in Hiroshima by saying, for example, that one one night of bombing in Tokyo many more people lost their lives. But in Hiroshima so many people died in the instant the bomb exploded. 70,000. In five seconds every building with a kilometre of the fireball were annihilated. Such terrible destructive power had never been seen before.

At the same time, horribly, it was treated as a scientific experiment. In the instant before the bomb was dropped, people reported seeing several small white parachutes falling from the Enola Gay. These were in fact radio transmitter probes designed to measure the atmospheric pressure in the vicinity of the bomb site. After Hiroshima had been selected as a target for a possible atomic bombing, no conventional bombing was carried out over the city so that the effects of atomic bombing could be better understood.

Hiroshima, thankfully, bears the weight of it’s terrible history very lightly. A beautiful warm ocean breeze permeates the city, and the evening the streets are buzzing with life and activity. I ate in two fine “okonomiyaki” restaurants both evenings I was there, a local speciality comprising many vegetables and seafood fried on a hot-plate before the customers. I am sure people ate okonomiyaki in Hiroshima on that day in August, too.

"For people who cannot go back home…"

"For people who cannot go back home…"

I’m in transit, between Nikko, celebrated pilgrim town, and Kanazawa, a town on the coast of the sea of Japan. The ocean has just became visible, a foggy band of water only dimly visible a few meters from the train tracks through thick grey cloud. I should arrive in Kanazawa in an hour or two.

I’ve been here in Japan since Saturday, and I’m on my way to Matsuayama for a conference — I’m taking the slow route, although trains in Japan are not that slow at all. Today is Tuesday, and I plan to be there on Sunday. My three days in Tokyo were exhausting, probably because I walked too much. On the first day I saw this sign–

To which I immediately attached a profound metaphysical significance. “You can’t go home again”, after all! These Japanese look after everything, even existential angst! Well, alright: I suspected it was a circumlocution for “homeless people”. But, in fact, none of the above: these shelters are really for salarymen who’ve missed their last train home.

I’m still on the misty coast of the sea of Japan. On the left I can see some snow-capped mountains behind a blue-grey mist and on the right, the ocean and many houses with black sloping rooves, wet with rain. It does look like it rains a lot here. The umbrella I bought on my first day in Asakusa will be useful around here.

My arrival in Tokyo was slightly surreal, as perhaps are all arrivals in unknown countries after long-haul flights. After descending through the clouds, absolutely nothing was visible until a few seconds before landing: Tokyo was shrouded a thick fog, and heavy rain was falling. I found my way easily enough to my hotel in Asakusa, but as it was only 9AM I couldn’t take a shower or readjust to the changing of continents. So I visited, in the pouring rain, Asakusa’s main attraction, the Senso-Ji buddhist temple. It was still early, and the crowds had yet to arrive, and I spent the good part of an hour wandering around the temple and the yet-to-be filled streets until exhaustion and rain overcame me. Remember, it was really around 3AM for me, and I had not slept in 24 hours. I decided to find somewhere warm to pass an hour or two until I could check in.

After time spent elsewhere in Asia (Iran and China) I had forgotten that actually the Japanese do know how to make a good coffee, and I found one such coffee-house where an extremely hot cup of coffee was prepared from beans for me before my eyes, which gave me just enough energy to keep going until 3pm.

I don’t have much else to report concerning my stay in Tokyo. After reading about the various districts of the town in my guidebook I had perhaps an exaggerated sense of the differences between them. My invariable reaction when stepping from the subway station was to think, actually, this looks very similar to all the places in Tokyo I have seen before. In the end, Asakusa, where my hotel was located, turned out to be the part of town I preferred. There I found everything on a more or less on a human scale, at least in the narrow streets around my hotel, where there were many fine restaurants and bars. Walking around Shinjuku was a bit like constantly watching television outside, so much is moving and changing. At certain intersections this is literally true: giant tv screens have been placed at major intersections, and everyone’s eyes drift skywards whilst waiting for the light to change so they can cross. And also there is a constant aural background of dozens of small voices speaking to you simultaneously in a language you don’t understand. There are I don’t know how many hidden loudspeakers in the metro system and visits to department stores and pachinko hall can be an overwhelming experience.

[a few hours later]. I’m now in Kanazawa. I’ll perhaps write more in the next few days as I continue down the coast.

Visiting Illycaffe, Trieste

Visiting Illycaffe, Trieste

In December I made a short visit to Trieste, Italy, where I was invited to give a seminar at the Trieste Observatory. Fantastic hospitality! I ate extremely well and was excellently looked after. Here’s a short account of what happened….

For espresso drinkers, Trieste is indelibly associated with the name of Illy. It was in Trieste that Illy created the first espresso machine, the Iletta, and Illy coffee beans is the only Italian espresso of high quality that is available throughout the world, thanks to the Illy method of packing the coffee beans with a neutral atmosphere under pressure. So I was amazed to discover, a few months previously, that the brother of my host was highly placed in the Illy coffee hierarchy and a seminar in Trieste seemed an ideal occasion to arrange for a visit to the Illy factory.

After my arrival, and an excellent meal near the observatory, at 3pm we drove to the Illy factory near the Trieste docks. It’s there, for almost a hundred years, that green beans have arrived from remote corners of the world to Illy’s factory. Crossing the port of Trieste we could see in the middle distance, on the hillside, a very tall chimney. This, I was told, was the chimney of the Illy coffee factory. The chimney is of such a great height so that only the freshest possible air is used in the roasting process; it’s actually an air intake, rather than an exhaust.

At Illy we were outfitted with visitor tags and of course the tour started with an excellent espresso! At the centre of the reception area is a gleaming bar where free cups of excellent espresso are served to anyone who asks. Here, where espresso was invented, one might regard this cup as the definitive version. I took an espresso with my friends and we talked to the bartender. It was indeed an excellent espresso; I realised now to what level I have to strive each afternoon at the IAP when I prepare espresso for my friends.

Our tour of the factory lasted over two hours, in the main part because myself and my colleagues were very inquisitive. Our tour started with the coffee bean selection process. We were led into a narrow glass-fronted room which overlooked what I can only describe as a waterfall of green coffee beans, a vast avalanche of coffee grains. Here the crucial selection process took place: the reflected light from each coffee bean is carefully examined and if it does not fall within a carefully pre-determined spectrum pffttt! it is ejected with a blast of compressed air. A few other coffee beans are naturally taken out with it but no matter: one bad coffee bean, we are told, is enough to spoil an entire cup of espresso.

After selection, the coffee beans are roasted and then travel in pipes propelled by compressed air to the packaging plant. Walking over there I stood amidst countless machines that relentlessly filled one coffee tin after another with Illy coffee beans and then carefully pressurised the tin with neutral gases. I realised that every single tin of Illy coffee in the entire world came from this factory: there is no other production facility. Illy also make their own tins, which are tested to make sure they don’t explode under pressure an automated process which which we witnessed (and were I nervously awaited an extremely large bang.) Throughout the shop floor I saw espresso machine after espresso machine: at each stage of the packaging process espresso coffee is regularly brewed and tasted (how do these people sleep at night?) to make sure that only the highest-quality product is shipped.

The most wondrous place, however, was the Illy coffee laboratory. Here it was explained to us how Illy selects the coffee beans which will be used in their espresso blend. When a sample of coffee beans arrive at the factory, they are first examined under the microscope, to make certain they have the correct colour and shape. Okay. But the next step I found quite amazing. Illy scientists make measurements of each coffee bean using a near-infrared spectrometer. Our guide pulled out a thick binder showing the results of such tests. I was amazed. These plots were what I as an astronomer would recognise as a colour-colour diagram; each axis shows the difference between two adjacent spectral filters. If an astronomer wants to find a distant galaxy, he looks for objects which fall into a particular region of colour-colour space. Galaxies at redshift of around three are here, lower-redshift galaxies are there. But at Illy, they carried out exactly the same experiment! Good coffee beans lurked in this region of colour-colour space, bad coffee beans in this one! I had always suspected that astronomy and espresso were intimately connected, but now I had proof.

We left the factory and returned to the observatory just as the winter light was fading. I worked for further hour or two at the observatory before leaving to eat an evening meal with my colleagues. The next morning, climbing up the hillside to the observatory before my talk, I made an interesting discovery…. I knew that Jimmy Joyce had lived in Trieste but I had not realised it was so close to the observatory…and, wasn’t that someone’s washing hanging out just next door?

I remembered Flan O’Brien’s hilarious Dalkey Archive, in which James Joyce has a double career stitching Jesuit underwear…
