a whole new city

It only occurred to me recently that the generations from my grandparents back to their grandparents lived in towns and cities most of the time. One of those who lived all their lives in cities was Heinrich the cellist, and I am beginning to realise that his biography lines up some amazing places, including several where I wouldn't mind living myself. As I raved about Elberfeld/Wuppertal recently, I am now also going to introduce some of the other places he lived, beginning with Strasbourg. He arrived there in April 1901 when he joined the army, and he stayed until April 1906, when his regiment was moved to a smaller town as a punishment (Strafversetzung), although I don’t know what crime they were being punished for. He also met his future wife there. Maria arrived in 1903 to train as a secretary and must have stayed until they married in 1908, so she, too, spent around five years in the city.

Strasbourg in 1901 must have been amazing. After the newly founded German Empire had taken over the city in 1871, it went to huge efforts to expand it and make it a showcase of urbanisation (while forcing the city itself to pay the bills for the works). Inspired by the grand boulevards in Paris built in the 1850s by Haussmann under Napoleon III, the new quarters (Neustadt) were to triple the built area of the city and increase the population from 80,000 to 180,000 by 1914.

A new main station, new university buildings, administration, theatres, churches as well as a synagogue, everything had to be of the finest and designed with style. Even the army barracks where our cellist lived for five years were looking amazing (Manteuffel-Kaserne, now Quartier Stirn, used as an education facility by the French army). From neo-classicism to art nouveau, everything was there and much of it is still there today. Ironically, even though it is now back on French territory, the Neustadt in Strasbourg is the best-preserved example of German urban architecture of that era, and has become part of a UNESCO World Heritage Site in 2017.

I have to admit, although I’ve visited Strasbourg a dozen times (without really thinking much about the old cellist), I never explored the Neustadt beyond the main station and the always identical path which led me from there into the medieval centre of the city, on the main island. Essentially, Rue du Maire Kuss throught to Place Kleber. (Heck, I've even spent a night in the Neustadt, staying at the Hotel du Rhin, opposite the station!) Last time I was there, I noticed the church St. Paul (shown above), which was part of the Neustadt development and was inspired by the gothic Elisabethkirche in Marburg, but I only saw it from across the water, from the main island. Have to go back and visit properly.

Further Reading:
The Neustadt has Wikipedia entries in nine different languages right now. The French entry is very good.

science news on the move

I started archiving the science news items here in January 2019 after tumblr started to hide my blog (which is also called proseandpassion), following the change to its censorship approach.

Recently, however, there have been days when blogger wasn't working when I needed it for the science news archive. As I have now started a new tumblr blog, which hasn't been hidden yet (prosepluspassion.tumblr.com), I'm now trying to move the science news back there, i.e. in addition to tweeting each item, I will also share it on tumblr with the tag "science" (plus up to four other tags for specific fields), so it should show up at https://prosepluspassion.tumblr.com/tagged/science.

You can access these pages without having an account with tumblr, just like any other blog. (If you do have an account, you can reblog them like you retweet things on twitter.) Seems to be working fine so far but let me know if there are any problems.

All other content that isn't strictly time sensitive, such as features, book reviews, etc remains here (and may be mirrored on tumblr if I remember to post the link). For these items it doesn't matter too much if the site isn't working one day and I have to post it the next.

bats revisited

Open Archive Day

A year ago, I wrote a feature about bats and why we should care about them and understand them better. I'm glad I included a section about viral loads, discussing the remarkable ability of bats to harbour viruses without getting noticeably sick. (In a rather interesting and complex way, this connects to their ability to fly.) Back then, the bat virus that served as an example was Ebola. Now it would obviously be the coronavirus that is causing COVID-19 and changing all our lives.

Which means that my feature is still topical in a way, and it is now freely accessible:

Why we should care about bats

Powered flight has enabled bats to expand into a wide variety of ecological niches from nectar feeding to insect hunting, making them one of the largest groups of mammals.

stars tell their stories

The science books I get to review for C&I can be a bit of a mixed bunch, but here's one I would wholeheartedly recommend to anybody interested in anything astro-related:

A History of the Universe in 21 Stars: (and 3 Imposters)
by Giles Sparrow
Welbeck, London 2020
ISBN 978-1-78739-465-0

A snippet from my review:

"In his beautifully packaged book, Giles Sparrow merges the old and the new way of telling stories about stars. He introduces us to 24 individual dots on the firmament with their constellation and mythical backstory, and then connects each of them with the part of our modern understanding of the Universe that each has helped to elucidate."

The long essay review is out in:

Chemistry & Industry Volume 84, Issue 11 November 2020 Page 38

On page 39 of the same issue I also have a short review of a book about food science, which wasn't quite as satisfying.

learning from Balzac

Balzac et la petite tailleuse chinoise

Dai Sijie

First published in 2000 and hugely successful, this is a short novel about two teenage boys caught up in Mao’s Cultural Revolution and sent to the remote countryside for re-education by the hardworking villagers. Instead, they find intellectual solace in an illicit stash of French novels by Balzac, Dumas, Flaubert et al. and also use them to re-educate themselves as well as the little seamstress of the title. Lives are changed, although perhaps not quite in the way they may have hoped.

(Cover of the 2001 folio edition I have, too. Later editions typically have images from the film.)

I managed to miss this when it came out and was swiftly made into a movie as well, I only vaguely remember seeing the title some time and wondering what it was about. Catching up with it now, I enjoyed the novel and I was amazed at how well it connected with my own experience of growing up around the same time. I was also stuck in the sticks, maybe not as remote and spectacular as the phoenix of the sky mountain villages with their dangerous paths, but still, as a vastly exaggerated fairytale metaphor for my youth, the novel works surprisingly well. And I found solace in the very same 19th century French novels. Today, I wouldn’t find time for Balzac, but I might revisit Flaubert one day.

It does make me think. Maybe there was a bit of Cultural Revolution going on in Europe as well? Between 1900 and 1960, everybody from whom I inherited DNA lived in towns and cities (eg Heinrich the cellist did all his life). Then, in the 1960s, People got cars, moved to the sticks, commuted to work. A slippery slope. I still get an allergic reaction when, ahead of the TV news, I see trailers for shows pretending that moving to the countryside is a good thing. The Cultural Revolution caused between 200,000 and 20 million deaths, depending on who you choose to believe, and traumatised millions like the author, Dai Sijie. We should heed that warning.

Prehistoric shark hid its largest teeth
Some, if not all, early sharks that lived 300 to 400 million years ago not only dropped their lower jaws downward but rotated them outwards when opening their mouths. This enabled them to make the best of their largest, sharpest and inward-facing teeth when catching prey, paleontologists at the Universities of Zurich and Chicago have now shown using CT scanning and 3D printing.

With mouths closed, the older, smaller teeth of the ancestors of today's sharks stood upright on the jaw, while the younger and larger teeth pointed towards the tongue and were thus invisible when the mouth was closed.

The technique uses gold nanoparticles to boost the signal from alkyne group tags attached to the molecules. The alkyne group has a minimal effect on the drug molecule behavior and provides a signal that can be easily distinguished from the cell background. Their technique is expected to be useful in drug discovery.

Hormones are the master regulators of sexual functions in mammals. The hormone oxytocin has a well-established role in social bonding, sexual function, maternal instinct, nursing, and lactation. Researchers from Okayama University have now explored the roles of oxytocin in male sexual function for the first time. Findings from the study suggest that oxytocin-mediated control of male sexual function via the spinal cord may in fact be instrumental in treating erectile dysfunction.

dinosaur dealings

For the last 20 years or so, the biography on my website included a statement along the lines that I write about "everything except dinosaurs" - so I now will have to change that, because my latest feature is actually about dinosaurs, and about the crazy commercialisation of their fossils.

In a sense this is related to the reason why I didn't cover dinosaurs - because they are getting too much attention already. The general public's obsession with dinosaurs has surely contributed to the phenomenon that people with more money than sense have started the craze of buying major fossils to set them up at their homes and impress their visitors with them. So mostly, the feature is about humans going crazy about dinosaurs:

a city through time

Looking into the 20th century transformations of Wuppertal (a conglomerate formed in 1929 the rivalling neighbour cities of Elberfeld and Barmen) to trace the steps of our old cellist, I was amazed at the changes around the Döppersberg station of the iconic suspension railway (Schwebebahn), next to the mainline station that is now Wuppertal Hauptbahnhof.

Looking from the station towards the historic centre of Elberfeld, postcards of 1902 show a futuristic Schwebebahn station on stilts looking like a spaceship has just landed, with the backdrop of a fairytale cityscape with spires and turrets. More to the point, perhaps, it could be an illustration from an original edition of a Jules Verne novel, and the whole Schwebebahn enterprise exudes the Verne spirit. Get on board for a ride through 1902 and into Döppersberg station (at 1:32) with this MoMA video (there is also a colourised version available and one juxtaposing the equivalent ride in 2015 - this last video is slower, the approach to Döppersberg is at 2:55).

By 1912 the spaceship is beginning to get sucked up by the surrounding architecture, but the fairytale cityscape remains intact:

Source (this site sells vintage postcards, but this one may have sold out).

My great-grandparents lived there from 1919 to 1960, and during these four decades the area changed beyond recognition, only the Schwebebahn line remains as a landmark. I am getting the impression that the widespread destruction in worldwar II wasn’t even the worst of it. After that came the planners thinking we have to get in more cars, and by 1974 it looked like this:

Source.

Further mess-ups followed, and when I visited this year, the whole area was still a building site, with a new Primark shop being about the only thing finished. Luckily the Schwebebahn has survived. No idea what it will look like when this round is done, but I’m quite sure the 1912 incarnation remains my favourite. I should say, however, that in the residential areas away from the main roads some of the art nouveau loveliness survives, and there are lots of green spaces in the city too, so mustn't grumble, and I'll be certainly happy to visit again.

Further postcards from Wuppertal are on twitter under the hashtag #talpost, and my photos from September are here.

What all this reminds me of is a series of 8 images by Jörg Müller of a fictional city going through the 20th century, published in 1976 as: Hier fällt ein Haus, dort steht ein Kran, und ewig droht der Baggerzahn. Many years ago I lived in a tiny room at the top of an old house in Marburg, where somebody had artfully displayed these images around the walls of the vast staircase. I think one followed the forward direction of the timeline while going up, but one could debate whether cities have really gone up or forward at all.

UPDATE 22.7.2022: In June I made another daytrip to Wuppertal and travelled the entire length of the Schwebebahn up and down, from Vohwinkel to Oberbarmen and back, with a few stops along the way. The redevelopment at Döppersberg is finished now, so I took lots of photos vaguely aligned with the perspective of the postcards above (didn't have them with me to find the exact spot). See my new Flickr album of the trip for lots of Wuppertal views.

crispr crowned

Open Archive Day

Slightly belated echo to this year's Nobel prize in chemistry for Jennifer Doudna and Emmanuelle Charpentier. When the prize was announced, I checked and found that I had already recycled my most recent feature on crispr (applications in agriculture, here), but I didn't think of the previous one, from the early days after the discovery of Crispr, and the nascent discussions on implications for bioethics.

In all of this, I had the advantage that I already knew Jennifer Doudna was brilliant. Nobel laureate Tom Cech told us so back in 1994(ish), when he gave a seminar at Oxford and implored us to remember his postdoc's name because she will go on and do great things. I've often remembered his words and reflected on his remarkable foresight.

Anyhow, my 2015 feature on Crispr, complete with a lovely photo of this year's laureates, is here:

Streichquartett Elberfeld 1927- Suchanzeige

NB The English version of this blog entry is here.

Ich suche immer noch nach den Geigern und dem Bratschenspieler in dem Streichquartett, das in den 1920er und 30er Jahren in Elberfeld / Wuppertal aktiv war.

Es löste sich auf, nachdem die Nazi-Behörden erfuhren dass einer der Musiker jüdischer Abstammung war und begannen, unseren Cellisten unter Druck zu setzen, er solle seine Freizeit nicht mit Juden verbringen. Eine kurze Fassung der Geschichte auf Englisch ist hier, eine längere auf Deutsch hier.

Ich habe eine Liste von mehr als 50 Freunden (und wenigen Freundinnen) deren Geburtstage unser Cellist jedes Jahr in seinen neuen Taschenkalender übertrug. Obwohl die erhaltenen Kalender aus einer späteren Zeit stammen, wäre es möglich, dass sich in der Liste auch überlebende Mitglieder des Streichquartetts finden könnten. Deshalb veröffentliche ich hier die Namen mit dem Geburtsjahr und der Straße, in der Hoffnung, dass jemand der nach diesen Namen sucht, vielleicht einen der Musiker wiedererkennt.

Personen die aus dem einen oder anderen Grund nicht in Frage kamen, habe ich ausgelassen, so bleiben uns immerhin 34 Namen. Die Straße mit dem Sternchen heißt heute Friedrich-Engels-Allee und ist der nach Pariser Vorbild angelegte große Boulevard, der Barmen und Elberfeld verband, die heute die größten Stadtteile von Wuppertal sind.

on the origins of numbers

When I saw the news story about the fraction signs of Linear A, the cuneiform writing system of ancient Minoans, I felt inspired to go looking for the origins of mathematics. I.e., I was asksing myself: where was the transition when natural abilities that you might also find in other animals led to calculating, book keeping, and the whole culture of mathematics that we have today.? I didn't really find that magic spark moment, but I still learned lots of interesting things about different cultures deal with numbers, and how scientists are debating the numerical (or just quantical) skills found in some animals.

The feature is out now:

second lockdown

Now a second lockdown is coming our way, so there will be plenty of quiet time to learn a second sarabande. The Bach project (36 movements in as many months) doesn't look quite as crazy now as it did in March. Although I also got to play tunes outdoors and with other people every once in a while, a couple of times under the remarkably reflective roof of the band stand in Florence Park.

I enjoyed the Gigue in C, which was my movement for October, and managed to memorise almost half of it, might get the other half into my head at some point, as it repeats many of the patterns I already know from the first half. I have now managed to memorise what was missing of the minuets from the first suite, so I can sort of play from memory the movements 4-6 of the first suite, along with most of the Courante, one of the Bourrees and bits of the others.

So onwards (or backwards, rather, as I did with the first suite) to the Sarabande in C. I'm starting with Inbal Segev's musings, as always, and I found recordings from:
Ophélie Gaillard
Alisa Weilerstein
I'm also adding these videos to my youtube playlist "cello repertoire".
