#OpenSource #regulation incoming! The @EUCommission is about to ask for feedback for: * a strategic approach to the open source sector in the EU that addresses the importance of open source as a crucial contribution to EU technological sovereignty, security and competitiveness * a strategic […]

I know this is pretty small beer in the light of world events, but I was not expecting to have to write “risk of invasion by the USA” into the risk assessment for my fieldwork in Greenland in June.

5/5 This work was led by our PhD student Chengyu Fang, in a collaboration with several others from our group, as well as the groups of Jennifer Choy and Mark Saffman, and Argonne National Laboratory The work was supported by DOE Q-NEXT and the NSF

Today I learned that when iceberg debris - clear bits of ice diamond - reach the shore of the glacier lake, the waves playing with them make a lovely trickling sound, almost like music, while the ice glitters in sunlight, sequin-like.

On feeling stupid. I read this pretty much every year... https://web.stanford.edu/~fukamit/schwartz-2008.pdf

Gerade zufällig in Augsburg in der Bäckergasse entdeckt… #openlab

Happy holidays, everyone! In this year's Christmas picture, I illustrate some aspect of #ai, but I made the picture itself without AI (rather, inkscape)... It is entitled "Attention / ... red apple under the tree is ..." Experts might figure it out... @MPI_ScienceOfLight

Book recommendation: Autobiography by Katalin Karikó, the Hungarian-born biochemist who provided the foundations for modern mRNA based vaccines and treatments. Her breakthrough paper together with Drew Weissman was rejected by Nature as 'only an incremental […] [Original post on fediscience.org]

Very cute letter from a school class that read our children’s book „Crumbles in Space“, where an astrophysicist and his daughter are making a tour of the universe. They liked it a lot, but wondered where is Mom in the story. Well, we had her initially as a […] [Original post on mastodon.social]

Vielen Dank an @ibohnet für das schöne Interview zu meinem Schaffen als Autorin (und Illustratorin). Es ist jedes mal toll, wenn die Fragen mich zum Nachdenken bringen - und wenn ich nach einem Gespräch das Gefühl habe, selbst was neues gelernt zu haben […]

What will happen when the arXiv is flooded by AI-generated/-aided papers? We discussed this question in our AI reading club recently. First, there's the obvious problem of shoddy work swamping the arXiv at scale and being progressively harder to detect. But let's zoom forward a bit and assume […]

For my lecture I cooked up a hopefully easy to follow yet accurate explanation of how large language models work (includes reference to Wittgenstein as bonus!). There are of course many attempts to popularize the techniques behind LLMs...let me know what you think about this one! […]

Heute berichte ich in der Frankfurter Allgemeinen Sonntagszeitung für Euch, wie Botaniker*innen im Stillen eine der größten und wichtigsten Rettungsmissionen für das Leben auf der Erde unternehmen. In Saatgutbanken sammeln und konservieren sie nicht nur die […] [Original post on mastodon.social]

RE: https://masto.canadiancivil.com/@paige/115718239051943653 Echoing this critical advice, especially to #science organizations. If you are a science organization on Bluesky and you want to expand your audience to the open, federated social web, just follow this bridge account. Then I --- an […]

Wooo it's up! New paper alert! I will write a summary thread about this paper tomorrow morning when I'm not quite as mentally exhausted! "An Orbital House of Cards: Frequent Megaconstellation Close Conjunctions" by Thiele, Heiland, Boley, & Lawler https://arxiv.org/abs/2512.09643 Not […]

I'm not often excited when I hear hiring news from big universities, but I'm seriously excited about this one - exciting news from my friend Sera! […]

A good reminder that the most important thing in doing art is too start. Thw first card was a battle of will against myselt, the second (this one) I easily fit into the two hours back in the hotel between visiting the radio astronomy institute and dinner […] [Original post on mastodon.social]

Ich habe einen neuen Lieblingshoodie und ich bin überglücklich, dass die liebe @Fuchskind mir dieses tolle Motiv extra freigestellt und in ihren Shop gepackt hat. 🚀

A lively halo from the flight to Buenos Aires today.

Wohooo! Erste amazon-Rezension für mein Buch (und bisher eine positive) 😊

Diesen Samstag in #Erlangen: "Was hat eine Breze mit Physik zu tun?" Prof. Flore Kunst erklärt, wie in der Physik Konzepte aus der Topologie angewendet werden (die unter anderem auch den Unterschied zwischen einer Breze und einem Krapfen erklären). Beginn […] [Original post on wisskomm.social]

Hi! Today is my first official day as the Executive Director of Mastodon, replacing @[email protected] as CEO. I joined the Mastodon team more than 5 years ago, mostly working for Mastodon in the evenings on top of a 120% day job. I was the driving force behind the incorporation of the […]

We’re still an absolute skeleton crew of 14 people, competing with teams sometimes 100x as large as ours. To get to our humble team size was only possible through the less than 1% community members who donate to Mastodon, a handful larger donations, & EU grants, all of which we are forever […]

Wohoo, mein Buch ist wieder direkt von Kosmos verfügbar 😊💫 Ich glaube übrigens, es macht sich gut als ein Chanukka-/Weihnachts-/Neujahrsgeschenk - gerne auch vom lokalen Buchladen 📚 https://www.kosmos.de/de/schwarze-locher_1180792_9783440180792

Die "Moderne Physik am Samstagmorgen" in #erlangen ist wieder zurück! Der erste Vortrag dieses Wintersemesters erklärt, wie momentan die "datengetriebene Wissenschaft" in rapidem Wandel begriffen ist, dank Konzepten wie #openscience. Der Vortrag von Prof. Heiko Weber findet am 22. November um […]

In Waterloo, Ontario, you find a hotel restaurant called 'proof'. :-)

Bücher von extrem coolen Menschen kaufen macht noch ein bisschen mehr Spaß als sowieso schon. 🤍 (Erst recht, wenn man eigentlich damit rechnet es bestellen zu müssen und dann haben die es einfach schon da.) (@vicgrinberg.mastodon.social.ap.brid.gy)

Others find peace and calm in knitting, I find it in preparing slides for my astronomy lectures for curious non-physics students :-) I'm quite pleased with my step-by-step spectroscopy slide, which starts with a "spectral glasses" photo and goes from there to a spectrum-as-diagram. 🧪🔭⚛️

Gedanken zu Wissenschaftskommunikation und (Wort-)Bildern aus meinem Buch: Wir Physiker*innen verwenden gerne Vergleiche aus dem Alltag: ob nun die Raumzeit als eine dünne Folie (oder Katzenhängematte 😺) oder das sich ausdehnende Universum mit Galaxien drin […] [Original post on mastodon.social]

Hallo? Wie Mega ist das den bitte? @Mastodon hat soeben stellvertretend für die Idee des #Fediverse den #grimmeonlineaward erhalten! ❤️ Euch und uns allen herzlichen Glückwunsch!!! 🍾

@FMarquardtGroup There is ongoing work to integrate ActivityPub within Solid: https://activitypods.org/ @activitypods can probably tell you more.

I have a bazillion new German followers (hello!), and I'm getting interviewed for German public radio in an hour about "sunlight as a service", and I don't speak any German and I've never been to Germany. The Fediverse is a truly magical place!

Today I learned that there are only three English cities with an electrical consumption greater than 200 megawatts: London, Manchester and Birmingham. By comparison, the people who want to build AI data centres here, which nobody asked for, want a supply of up to 1 gigawatt (1,000 megawatts) for […]
