Here are some photographs from our recent trip to Bangkok.
First, a series of photographs taken (mostly) in and around the markets in Bangkok. It’s really wonderful taking photographs there, there are so many things to see. Returning to Paris, one feels that the city is strangely empty.
But what did the city feel like? Something like this, I think:
Now to post some photographs from Japan, too…
I made a short trip with ML to Budapest a few weeks ago. Budapest is one of those cities I visited when I first ‘discovered’ Europe in the early 90s before leaving for Canada for two years. Quite a few of those cities I have never returned to since then: Budapest, Prague, Vienna. You see, back then, I was attracted to this part of the world. For me Europe was above all Mitteleuropa, it was not the Mediterranean Europe of France, Spain and Italy. In fact, during those first few visits to Europe, I didn’t even visit Italy. Coming from the North, for me Italy seemed to be chaotic and noisy. Today, of course, I feel differently. But meanwhile, in my mind, Budapest rests frozen in the summer of 1991. What it would be like today?
After a short flight from Orly, we arrived at night:
it was bitterly cold, but I had my heavy coat for the mountains.
There is certainly a particular atmosphere in this city at night,
and at the same time there is no question that things have changed,
and the city is not as it was before. Although Budapest, as I learned, was always even in the depths of communism, a city known for its cosmopolitan lifestyle. But now some strange choices are being proposed:
However, some things do not change, people still swim outside in at Széchenyi in winter when the temperature is barely above freezing:
There are still a few mysterious things to see,
Many buildings have been restored, but not all of them,
there are still a few traces left from before the arrival of modern-day plate-glass windows,
Certainly food is important,
and during our stay we went to some wonderful bars and restaurants,
and outside in streets, you certainly need to wrap up warm:
And suddenly it was time to leave. Waiting at Budapest airport to board the plane in the depths of winter is a unique experience:
… and we were back in Paris once again. I enjoyed immensely our short visit, and hope to return soon…
The Observatoire de Haute-Provence (OHP, as we call it to save words) is remote. To get there, you take the TGV to Aix-en-Provence, and then rent a car and drive north for around an hour. The nearest town is Manosque and the observatory is in the mountains. Each year I go there with two other astronomers to teach observational astronomy to a group of Masters-level students. The course is organised by Herve Dole who meticulously sorts everything out, helped out a lot of course by people at OHP and the Universities. We usually have two or three nights on the 120cm and 80cm telescopes, and usually it is clear for around two or two of those nights. There is a lot of work involved: for each group of students, there is a full scientific project, starting from planning the observations and finishing with a report and presentation. This year was particularly interesting: we successfully managed to observe an a transiting exoplanet, a planet which passes in front of its star and causes its light to dim.
The story of OHP is a long one. Observations started here at around the same time the IAP (Institut d’Astrophysique de Paris) was created a story which you can read about here. At the start, the OHP was, more or less, the “observing station” of the IAP, a place where the latest instruments could be tested out and where the still-new field of astrophysics could get the data it needed. I won’t go into the whole history of OHP here, but a succession of larger telescopes were built there, culminating with the mighty 193cm telescope in 1958. It was with this telescope that astronomers made the discovery of the first planet outside our solar system, 51 Peg, in 1995. The funny story here is that around the time I was studying for my Masters’ degree in Victoria, astronomers there were using an almost identical telescope at the Dominion Astrophysical Observatory for the same scientific project (with different instruments). Alas, their control of systematic errors was not quite good enough; they missed out.
The situation at OHP has evolved. The number of astronomers using the site has greatly decreased in the last few decades with the arrival of other astronomical observatories situated in locations like Hawaii and Chile. Investments in the site have declined, reflecting a policy of concentrating resources in larger telescopes further away. But there is a lot to be said for smaller telescopes with modern instrumentation nearby, as I saw when I visited the JPASS observatory in Spain in 2015. There they have constructed a new small modern telescope on a site like OHP but with modern state-of-the-art detectors. Despite spending a lot of my time working on larger projects, I think there is a lot to be said for keeping sites like OHP open providing a compelling niche can be found.
Today, there are only a few people around after the sun sets. Although there are many telescopes, only one or two are regularly used. Some have been converted to remote, robotic operation. In the past, a chef cooked legendary evening meals each night, but today we re-heat meals made earlier in the day in the microwave (which never get things quite hot enough.) Still, the observatory has decided that educating students in the techniques of observational astronomy is a priority, and each year many nights of telescope time are dedicated to student projects. There is accommodation on-site which is very comfortable. The course that I teach in is part of the Master 2 program for astronomy in the Paris region, and we have tried very hard to keep an empirical, practical approach to our course. You wouldn’t expect it, but fewer and fewer astronomers actually travel to telescopes these days, and I personally appreciate seeing in person the telescope and dectectors even if they are not at the forefront of technology.
This year is my second trip to OHP with film cameras. I wanted to capture something of the feeling of being there in the middle of winter. Each morning one could see wonderful things like this:
Here are a a few photographs I took around the observatory during the day.
And as night falls, time to observe, or eat, depending if your observations are finished or not.
As each year, we stayed a week, arriving on Saturday afternoon and leaving early on the following Saturday. It was kind of nice to be slightly abstracted of the concerns of everyday life. When I wasn’t working, I worked on my article for Emulsive. I learned things. I learned that there is such a thing as the “Qatari Exoplanet survey” and our students successfully confirmed one of their transiting exoplanets (and I actually did a fair amount of work aligning their hundreds of images for them). We ate galette, which is a long tradition in France and in Provence it’s even better. And I took a lot of photographs of trees and domes. And group photographs. The best ones are always the unplanned ones. Like this one, taken at sunset. Almost everyone is there, except Herve, but here it is anyway:
I am already looking forward to returning in 2018!
