Düsseldorf

... some snaps from Düsseldorf. First the mythical water creatures known as Flossies, which apparently emerge from the river Rhine and climb up otherwise unremarkable buildings:



A building by the waterside in the former harbour area, obviously inspired by the former use of the area:



... and going inland, a 3D work of art on a wall near the station of D-Bilk:

Pension Düsselmann, Bad Nauheim

During my recent trip to Germany, I visited the spa town of Bad Nauheim, where my great-aunt and great-grandmother used to live, for the first time in nearly 30 years. My great-aunt, Esther Düsselmann, used to have a bed & breakfast which around 1973 looked like this: On my visit I was pleased to find out that the people who bought the house in the 1980s have renovated it very nicely and are still using it (as offices): Only the garden looks as messy as ever, so I had to take the picture from the side, as the house is barely visible from the front. Bad Nauheim is of course famous for the early 20th century spa buildings: ... and for the fact that Elvis resided there during his military service in nearby Friedberg: PS More about the Düsselmann family is to be found in this blog entry and in the links therein. Update 8.12.2024 I revisited Bad Nauheim last month, and the house looks still splendid. The hedge is now tidier than it was in 2010, so the house is better visible. See my photos on flickr.

recycle your P

scientists at Arizona State University are launching the Sustainable Phosphorus Initiative today (details of launch event). The initiative is led by ASU ecologist James Elser, sustainability expert Daniel Childers, and business professor Mark Edwards. They highlight the fact that the current use of phosphorus is highly unsustainable, and must be changed urgently.

Phosphate minerals are mined mainly in five countries, and 90% of the production goes into fertilisers, meaning that if "peak phosphorus" comes to pass, which will likely happen around the middle of this century, it will immediately hit global food production.

So recycling of phosphate-rich waste, e.g. sewage should become a priority ...

More on this later.

paris by day

This time, we only spent a night and half a day at Paris, so the photo yield is somewhat limited, but here are a few day-time snaps.

We explored the covered-up part of the Canal St Martin down to Bastille place, and discovered this exotic-looking place:



I always check the fountain next to the Beaubourg, with the sculptures by Niki de St Phalle but we were out of luck, as the fountains weren't on:



A new discovery was this DNA-like (?) sculpture in the Tuileries, which stands slightly bent, so I have one photo where the sculpture is straight but the ground is sloping, and this one where the ground is straight but the sculpture threatens to fall over:



Pix from various stops in Germany to follow ...

paris by night

I have lots of photos to sort out from my trip, here's a couple of shots of paris by night to start with:





In case it isn't obvious, the second photo shows a "Vélib'" bike rental station. Each bike dock has a green diode when the bike is there and ready to use (I assume), so at night, when all the bikes are there, the whole row gets this nice green glow reflected in the wire baskets. By day, the bikes get used a lot, one sees them whizzing about everywhere.

I've also just uploaded a new photo to fotocommunity.

wave power rules in Scotland

An assorted collection of wave and tidal power devices is to be deployed off the coasts of Scotland within the next ten years, demonstrating that there is a choice of technologies available to harness marine energy, but also that we aren't quite sure yet which of these technologies is going to be the most efficient one in practice.

I wrote a news feature about this for Current Biology, which came out last week while I was away and offline:

adventure travel

getting back from Germany yesterday was a bit of an adventure, but we made it! That's me, two kids, seven items of luggage including a very large African drum, and all that on trains overcrowded with stranded air passengers. At one point our train to Brussels was 100 minutes late:



but at the end of the day, and after some further struggles with the usual "lines closed due to scheduled engineering work" that hits UK rail services every weekend, we came home just one hour later than anticipated. Feels like a real achievement, given that this has probably been the worst travel chaos to hit Europe in living memory.

Following the news I was also intrigued re. how many people use pointless short-haul flights in a country that has an excellent network of intercity trains with services every hour and guaranteed connections on the opposite side of the same platform. Entire football teams, I learned this weekend, routinely fly to their away matches, even if the trip is only a couple of hours by train. Serves them right, now they have to share overcrowded trains with their drunken fans.

Henrich Tüselmann

Newly discovered documents show that the earliest known ancestor of the Düsselmann family (whose numerous descendants I've listed here) called himself Henrich Tüselmann (Tusselmann), and he was a miller at Dahlhausen, which is now a part of Bochum. He died 1770 at the age of 68. His first children appear to have been born at Strünkede, which today is part of Herne, and just a few kilometers north of Dahlhausen.

In 1730 he married Anna Elisabeth Siepmanns (more Siepmann history). They had 10 sons (including my ancestor Georg Wilhelm Tusselmann / Düsselmann) and 3 daughters. She died 1788 aged 82.

I was shocked to see the spelling with a T at the beginning - I had never even considered looking for that. It looks like there are 28 phonebook entries for Tüsselmann across Germany, most of them just a bit southwest of Bochum, in the districts of Mettmann and Wuppertal. For Tüselmann (only one s) there are even more (50), and the highest concentration of Tüselmann people is in Bochum and in the neighbouring Ennepe-Ruhr-district.

PS the Düsselmanns are of course linked to the de la Strada family, and I am intrigued to see that my blog entry on the Stradas appears to attract quite a few readers via google searches.

PPS Potential parents for Henrich Tüselman are Joh. Tusellman and Maria Arndts, who got married 30.11.1696 at Herne.

the big issue

The current issue of the magazine The Big Issue (that's the one sold by homeless people on street corners) has a cover story on "Shakira - Activist. Philanthropist. Pop goddess." Old photos, but a new interview. A lot about her education work, some hints re the forthcoming album in Spanish (not really thrilled to hear that she's writing material in English for that one, in my humble opinion the Spanish stuff is still better!) and the next tour, but no firm dates.

Anyhow. Another cover for the collection:

peeling patterns

The new banner picture fits my occasional series "Things I like the look/design of," as I like the patterns and textures revealed when paint, plaster, or other surface coatings come off. As for instance, on the walls of houses in Venice, where the water eats away all attempts at covering up the bricks.

In this case it's from a tree though - I think it's a plane, and I think it shed its bark naturally. But no guarantee, as I don't know much about biology above the cellular level ...
