08. November 1915 [...] Feldw. Winkler wird von den weit umher fliegenden Granatsplittern auf seinem Gange zum Komp. Führer überrascht und tritt schleunigst den Rückweg an. Abends. wird ein deutscher Flieger von den Franzosen lebhaft aber erfolglos mit Gewehrfeuer begrüßt. [...]

6.11.25 ca 10:30 #Mainz: Die Geschäftsführer des kommunalen #Wohnungsbau Unternehmens lassen sich von einer Drohne dabei filmen, wie sie ein Solarpanel aus dem 3. Stock werfen - soll wohl zeigen wie gefährlich #BalkonSolar sei. 🤷‍♂️🤦‍♀️👎

In vorfreudiger Erwartung auf den #39C3 – Ihr seid dran! Wir wollen in zwei Wochen aus der noch unsortierten Liste der Vorträge ein komplettes Programm bauen und brauchen dazu wieder eure Hilfe: events.ccc.de/2025/11/06/3...

Wer sich überlegt was man gegen den Rechtsruck machen kann. Eine Spende an einen der hier genannten Vereine wäre sicherlich ein kleiner Anfang!

The Government needs to get serious about climate change. And it hasn't so we're suing. But this is the longest and most expensive legal letter Good Law Project has ever sent - and it involves a huge team of specialist lawyers. And we really could use your help. goodlaw.social/4cqi

On Friday I went to a fitness studio for the first time in my life. On Saturday I went on a 18km hike. On Sunday I am wondering why my muscles are sore 🤔 Well that wasn't great timing, but at least the views were amazing.

The Paris Agreement offers a powerful framework for a fairer, healthier world. But as extreme heat shows, every tenth of a degree matters. We need higher ambition to stop violating the rights of ever more people. - new @wwattribution.bsky.social study www.worldweatherattribution.org/ten-years-of...

Today for the first time in my life I've been inside a commercial fitness gym. I have previously been in school gymnasiums, and in the tiny gym of Wadham College (long live Wadham Women's Weightlifting). Turns out when you go to a test training to check out the gym, you actually have to do sports!

I am cautiously delighted with the news coming out of the Netherlands. The exit polls are indicating that Geert Wilders has lost big and the Netherlands may get a center left government. Lots still unclear and forming a coalition won't be easy. But still, I am relieved and hopeful

28.10.1915 Auch heute ist es wieder sehr kalt, die Schneedecke ist aber wieder fort. Es fliegen viele fdl. Flieger über uns hinweg, welche von unseren Geschützen befeuert werden. Seit langem hört man wiedereinmal das bekannte Pfeifen der Artilleriegeschosse. [...] kurts1662tage.de/2025/10/28/d...

Waking up in Germany and somehow my entire feed is North Americans talking about some extra long baseball game. So: 1. Good morning! 2.Whats up with this game? Can I get a summary? 3. Shouldn't you be in bed?

Habe gerade beide Folgen des neuen Podcasts @neudenken-podcast.bsky.social von @beyond-ideology.bsky.social gehört. Mit welch erfrischender Ruhe und Tiefe hier wichtige gesellschaftliche Themen beleuchtet werden! Ein inhaltlich tiefgründiger Hörgenuss! Ich freue mich auf die nächste Folge!

Time for the final part of my conference trip to Valencia. Today the goal is to get from Narbonne to Freiburg (Breisgau). But I have some time before the first train. So let's go find some breakfast in Narbonne. The historic market hall seems like a great spot to do that.

A week ago I travelled South to attend two conferences in Valencia. Today it is time to make my way back North. First came a 4hour bus from Valencia to Barcelona.

What a great conference trip to Valencia! One week listening to talks, presenting my groups research, discussing ideas with colleagues from all over the world and meeting scientists I did not yet know. So many fascinating new research results! I am a bit exhausted and also inspired and intrigued.

Only about twenty of these unusual ‘birdcage’ vases are known to have survived to the present day. They were made in Japan in the 18th century at the famous Arita kilns, but they were designed to be exported to the Western market.

Es ist immer wieder tragisch wie Kurt im Herbst 1915 an der Westfront auf Frieden hofft. Er hofft der Krieg ist bald vorbei, wir wissen dass das Ende noch in weiter Ferne liegt. #WW1

Von wegen „Blaue Welle“: die #NoAfD verliert in den Kommunen gerade eine Wahl nach der anderen. Die Medien sollten die Legende vom ungebrochenen Erfolg der Rechtsextremen nicht selbst verstärken. Denn wenn wir Demokraten eigene Themen setzen - statt die AfD-Agenda zu übernehmen - gewinnen wir.

Not sure where you all came from, but there is now 2000 of you following me 🎉 Time for a reintroduction where I list some facts about myself and you are welcome to ask questions!

Can you spot the flamingos?

Ich finde auch, dass wir den Umgang mit der AfD normalisieren sollten: Normal im Sinne des Grundgesetzes wäre es, ein Verbotsverfahren gegen diese Partei einzuleiten. Das wäre die Normalität, die wir brauchen!

Guess what this sculpture is made out of

Good morning! Come with me as I make my way across Europe to attend a conference on materials research for sustainable development. #matsus25 #solarenergy 🧪

Mesmerizing delightfully colourful sculptures at the Katharine Grosse exhibition in Stuttgart. Highly recommended!

The German grassroots campaign organisation Campact has won a preliminary injunction against X.AI. The case started cause Grok had generated and shared untrue statements about Campact. The court ruled that X.AI was responsible and had to stop Grok from making false statements about Campact.

Well, what is wrong? Let me show you. These tram overhead wires shouldn't be this dangly 😬

Something is wrong at my tram stop. Can you spot the problem?

Many Congratulations to Walburga Hemetsberger on winning the Becquerel Prize! I couldn't stand that her name on the prize's page was a link to nowhere on @wikipedia.org, so I fixed that and started her article. #womeninred #womenintech #solar #energytransition en.wikipedia.org/wiki/Walburg...

If your job was to decarbonize by 2050 a big university in a state with hot summers, cold winters, and the 4th dirtiest electricity of any US state, what would you do? No nearby lake or big river, unremarkable geothermal resources, no safe/suitable site for nuclear on campus.

Some good news. London is meeting legal limits for toxic NO2 pollution for the first time – almost 200 years earlier than predicted – following the Mayor’s "world leading air pollution policies," City Hall announces. The Ultra Low Emissions Zone - and similar policies - really do work.

Der heutige Eintrag aus Kurt's Weltkriegstagebuch ist besonders stark vom Propaganda beeinflusst. Kriegsverbrechen gegen Belgische Zivilisten werden geleugnet und der Pfarrer verspricht die Einheit sei berufen sich besonders hervorzutun. Es ist gruselig das 110 Jahre später zu lesen.

The @nature.com conference on #perovskites for #solar in Stuttgart has the best conference goodies! #photovoltaics

Very proud of my student Mohamed Mahmoud who won a student award for his excellent conference presentation. Amazing finale to @eupvsec.org in #Bilbao! #science #solar 🧪

hello blueskies! i am nora and i have a fused glass jewelry shop. i would love to send you something beautiful! nora.jewelry #bsnm

"on a technicality" Not really. A failure to get necessary consents to a terror charge is not a slight error. They are safeguards when a person faces a serious charge. Prosecutors should take such safeguards seriously: this is terrorism law they are using. www.theguardian.com/music/2025/s...

Located between Aachen and Cologne, the Hambach coal mine is the largest in Europe. Run by the mega-corporation RWE, the toxic pit supplies the surrounding weapons factories with electricity, and pumps untold quantities of carbon dioxide into the atmosphere. freedomnews.org.uk/2025/09/26/g...

This is a 'small' lignite mine on the former GDR border, the scar is so deep and wide. With it's own cloud ceiling in the morning. 150Mt CO2 emitted and it still emits by sitting there with exposed, once sequestered carbon. Burning stuff is the past. Don't live in the past.

Even back in the 70s and 80s when I could be hassled by the police for walking while trans, no one ever tried to stop me pissing in the Ladies or tried to make me change into my swimsuit among men. There is no dignity or respect involved in taking away rights I have exercised freely for forty years

Delightful first half of @eupvsec.org conference in Bilbao! Very proud of my students for their brilliant presentation of our science! 🧪

Danke an alle Menschen, die heute mit Fridays For Future auf die Straße gehen! 💚 Die Pläne der Bundesregierung, neue Gasfelder zu erschließen und Gaskraftwerke zu bauen, bedeuten nichts anderes als die Zementierung des fossilen Zeitalters. #ExitGasEnterFuture #DrawTheLine

seems pretty hard to argue with

Predictive text models do not ever "answer your question" They predict what an answer to your question would probably look like. Which is very, very, very different

16.09.1915 [...] Gegen Abend beginnt plötzlich ein furchtbares Infanteriefeuer, unterbrochen vom Krachen von Handgranaten und Artillerie. Zwischen den Bäumen hindurch sieht man Leuchtkugeln fliegen, so daß wir fest an einen feindl. Angriffsversuch glaubten. [...] kurts1662tage.de/2025/09/16/d...

11.09.1915 [..]Der Feldwebel brachte die Nachricht, daß der Artilleriebeobachtungsstand, von welchem ich neulich in die feindliche Landschaft hinübersah, von feindl. Granaten zerschossen worden ist. Das I. Batl hatte 1 Toten, diesem war die Schlagader zerschossen, sodaß er an Verblutung starb.[..]

Scratching the surface is not enough! This should be a guiding principle of good science - and politics 😉 . But it also applies to #photovoltaics! www.ise.fraunhofer.de/en/press-med... © Universität Freiburg / Foto: Silvia Wolf

Together with @uni-freiburg.de and KAUST we showed that surface passivation of perovskite top cells is possible in solar cell tandems with today's industry standard for solar cells. Read here why this matters: s.fhg.de/T4N6 or directly in the #Science article: www.science.org/doi/10.1126/...

Nachrichten, die häufiger verbreitet werden sollten: Die AfD hat heute zwei Wahlen um Rathäuser im Osten verloren. In #Wolmirstedt (Sachsen-Anhalt) und #Meißen (Sachsen) setzten sich jeweils andere Kandidaten im 1. Wahlgang durch. Die AfD ist schlagbar. Der Nimbus der Unbesiegbarkeit ist Taktik.

Under the terms of the deal, Anthropic will pay about $3K/book, Nelson said, w/ about 500K books expected to be eligible. But $0 for us authors (our employers) of scientific articles scraped for same profiteering, unfair use, b/c no one to represent us. Yet THEY "advance scientific discovery”? 🧪
