Thanks to a passing mention on my favourite philosophical corner of the internet photographic Universe the measurement on the beam has been moved away from zero (with a light fall, with lumps, at 5:30, as policeman Fox would say). But as these days I’m trying to keep to my promise of publishing at least one photograph per week with a short text does mean that my longer articles are swamped. So here’s small list…
I was happy to read that Film Ferrania have almost resolved their manufacturing problems. Shooting unique special films like their P30 emulsion is one of the best reasons I can think of to shoot film. Here’s my article about P30:
… and we built shopping malls where there were once houses. So begins a nine-day trip to Germany, to Bonn (for a meeting), Cologne and Essen. The very first thing one sees stepping out of the central train station in Cologne is of course the famous Cologne cathedral. The cathedral is much larger than any cathedral I know of in France, and a quick glance at Wikipedia reveals why: it was completed at the end of the 19th century, when our knowledge of engineering and our ability to cast steel beams (I suppose) was significantly more advanced. One could at last make very large cathedrals without running into annoying problems like they did at Beauvais with bits of the building collapsing (Beauvais cathedral was never actually finished and inside there are many wooden beams holding the building together).
Cologne cathedral, I learned, is the most visited tourist attraction in Germany (presumably because of the close proximity of the train station). Inside, tourists are confined to a tiny corner of the building. It means there are terrible crowds, which is ironic because gothic cathedrals were invented by Abbé Suger as essentially a crowd-control technique, a way to get as many of the faithful as quickly as possible around the relics in the shortest possible time. In Cologne, it seems, tourists do not benefit from this innovation.
The centre of Cologne, of course, was terribly destroyed in the war, and afterwards not much thought seems to have been given as to how to rebuild it. So it goes, as a certain American writer might have said.
Yes, now I am travelling again after a long period in Paris. I spent one night in Grenoble (where I saw an old friend again after a long time) and in the morning early before my meeting I walked around looking for what could be a photograph. Grenoble is a strange place, there is an inner core of old buildings, surrounded by a larger layer of 70s-era tower-blocks, and beyond that the mountains. On a June morning like this one it’s a pleasant enough place. But here’s no photographs of buildings and mountains, just sunlight grazing a building sometime in the early morning.
52 photographs (2018) #21: Perhaps one of the most important teapots in astronomy
This is is perhaps one of the most important teapots in astronomy, it’s the teapot used to brew and serve tea during Cambridge’s Institute for Astronomy tea breaks. Much of scientific research in the UK is fuelled by the consumption of large amounts of tea, and the tea break is an an important ritual in research life there. In fact, one of my first experiences in astronomy was as a work-experience student at the Armagh Observatory sometime in the 1980s. I was most impressed by the tea-break! I never saw so many people together discussing such obscure and interesting topics. I think that was the moment I realised that I wanted to be an astronomer.
