One week left to apply for a postdoc position in my research group. Want to research perovskite based optoelectronic devices? Check out this opportunity: uni-freiburg.de/stellenangeb...

#39c3: Our chair @simoneherpich.bsky.social & @pv-physicist.bsky.social will present 20:10 at "Ground": "Recharge your batteries with us - an empowering journey through the energy transition" about wind turbines, electricity rebells, heat pumps and solar! fahrplan.events.ccc.de/congress/202...

Good morning! Who is ready for day 2 of #39C3?

#39C3 is very very shiny

WiFi Access Point at #39C3 is buffering.....

In undergrad, I was a theatre kid. Did three productions and saw nearly every one of the 12 each year at the uni theatre (often worked the door/etc). I nearly picked it as a career. Nothing (NOTHING) compares to the heart-filling joy of just clicking with a cast/crew during/at the end of a run.

Me and my oversized prop are on the train to Hamburg and ready for #39C3 See you there!

The Christmas lunch assembly line is in full swing. Only authorised personnel is allowed in the kitchen.

Got a phone stand for Christmas that I am immediately putting to good use.

.... nachdem der Regen ausgesetzt hatte, wurden im Schützengraben Weihnachtslieder in die schwarze, stille Nacht hinein gesungen. Dies war der feierlichste Augenblick des Kriegsweihnachtens 1915. [...] Am Tage wütete rechts von uns nach Blamont -Leintrey zu ein heftiges Artilleriefeuer. ....

Hattet ihr auch Ölsardinen im Weihnachtspaket?

After a little sidequest in a room full of vending machines, I am now actually on the train and heading North. It is a tad foggy.

I am way early at the train station and am entertaining myself with a visit to the vending machine room. It is elaborate!

I wonder if our audience at #39C3 will be as attentive as today's rehearsal audience 🤔 @simoneherpich.bsky.social

Selbst an der Front im 1. Weltkrieg naht Weihnachten

14. Dezember 1915 [...] Von der 2. Komp. ist ein Pferd der Feldküche gestorben . Die armen Tiere haben es jetzt bei dem Tauwetter auf den schlammigen bergigen Waldwegen furchtbar schwer. Sie fahren die schweren Feldküchen täglich 3 mal in die Stellung und zurück. ...

The taste of my childhood Christmas concentrated in one package

I first learnt about Germany's hunger for horribly inefficent and polluting lignite in 2018 was when the church of St Lambertus, Erkelenz-Immerath (medieval site, but Neo-Romanesque build of 1888-91) was demolished, along with the entire village to make way for expansion of Garzweiler open pit mine.

I have written long threads about two coal power plants in Germany. Jänschwalde (in the East) and Neurath (in the West). Why did I do that? To highlight the impacts fossil fuel power plants have. #1 bsky.app/profile/pv-p... #2 bsky.app/profile/pv-p...

Let's think about fossil fuel power plants for a moment. For example Neurath power plant in the west of Germany. In 2019 it was the second biggest single emitter of CO2 in the whole European Union as well as the 102nd one world wide. en.wikipedia.org/wiki/Neurath...

Plotting for #39C3 with @simoneherpich.bsky.social tonight. In Hamburg we'll talk about the energy transition. Come recharge your batteries with us!

The US National Renewable Energy Laboratory (NREL) has been the bright star of renewable energy and especially solar energy research for decades. In a symbolic move it was yesterday renamed to National Laboratory of the Rockies. www.gravityisgone.com/a-collective...

And finally, today, one year after launching my first LGBTree pride pin to help fund transition, I'm launching another tree! This time the trees are decorated for Christmas as part of my winter pin drop! canopyrobin.etsy.com/listing/4405...

The sun is rising over frosty fields and I am already on a train. Good morning!

We’re facing an emergency. We understand how busy MPs are, but ask them to change plans to attend this crucial briefing. Top scientists will set out latest threats and key actions so MPs can protect the public. Please click to see if your MP is coming: www.nebriefing.org #TimeToStepUp #NEB2025

Good night crows #Berlin #birds #birding

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.

What are you looking at? Us? We are just two of thousands of hooded crows settling down for the night!

A little late night treat!

18.11.1915 Kurts Tagebucheintrag aus dem 1.Weltkrieg

Da bricht er eine Diskussion über die angebliche Bevorzugung von Frauen in STEM vom Zaun, nur um dann zuzugehen dass er keine Ahnung von dem zahlreichen Quellen hat. Die UNESCO, IOP, etc. hab ich schon geliefert. Wer möchte noch seine / ihre Lieblingsstudie zur Diskriminierung von Frauen beitragen?

A guy makes ONE tiny mistake (has a years-long friendship with the world's worst sex trafficker; brags about sexually harassing colleagues; is racist; says women are stupid) and his whole LIFE is blown up (does slightly fewer speaking engagements; keeps teaching at #1 university)??!?!?!?!?!

Sometimes even a wet grey autumn day can have vibrant moments. What vibrant moment did you spot today?

Ein 350 Millionen schweres Steuergeschenk für die Luftverkehrsindustrie raushauen, das Bahnfahrende mit der Verteuerung des Deutschlandtickets querfinanzieren. Chapeau: Das ist Robin Hood rückwärts bei gleichzeitiger Klimazerstörung.
