seen on fast trains to and from Paris lately: The SNCF drastically undersells the environmental advantage of taking the train. the 3g-to-260g difference is actually much more drastic and thus should also look like it - here 87x difference looks only like 4x. I don’t want to go all Tufte on French rail, but excusez-moi: the illustrations and colors can stay, but accurate representation matters.

PS: the trains were punctual!!

🚀 Als Herzstück von Orion bringt das European Service Module (ESM) die Artemis II Crew zum Mond. Es liefert den Hauptantrieb für den Flug, erzeugt Strom über seine Solarpaneele und stellt Wasser, Sauerstoff sowie die Temperaturregelung für die Crew bereit. Entwickelt unter europäischer Führung mit deutschen Anteil von 50 %, ist es erstmals ein nicht-US-amerikanisches System, das Menschen sicher Richtung Mond transportiert. Ein Schlüsseltechnologiebeitrag für die internationale Raumfahrt!

Remember when a “legitimate argument” peddled against #EVs was the power grid would fail? Too much strain? Oh WOE be to the power lines! Grandma will DIE in her home in August because YOU plugged in!

Yet suddenly we are full steam ahead building #datacenters the size of Manhattan to make banana pics. #AI #slop. And the electric demand will be colossal and constant.

Society and the world needs to stop being fooled and corralled by interests that don’t care about you.

🛰️ 'Miracle': Europe reconnects with lost spacecraft

「 The lost spacecraft had been "tumbling" when an ESA team in Spain "saw that some sunlight is actually hitting the solar panels," Aschbacher explained.
They seized the chance, using this small amount of power to re-establish a connection.
The spacecraft's solar panel is now facing the sun, allowing it to charge its batteries 」

'Miracle': Europe reconnects with lost spacecraft

The European Space Agency announced Thursday it has re-established communication with a spacecraft that is part of its Proba-3 mission, after losing contact with the satellite a month ago.

Arts and Science Residency – Call for proposals

The Department of Astrophysical and Cosmological Relativity at @mpi_grav Potsdam has teamed up with the Center of Gravity at the Niels Bohr Institute in Copenhagen.

The two institutions are offering a joint arts and science residency program, with residencies available at each site for up to three months.

Darya, 24, and Donya, 20, were studying to become medical nurses at the University West campus in Trollhättan, SW Sweden and had been in Sweden for 7 years after being granted temporary residence because they were related to their father, but when they turned 18 being related was removed as grounds for residency and the (anti-)Migration Agency decided to deny them work permit due bureaucratic nonsense (had extra work as carer and at major hamburger chain, but hadn't gotten those through the Govt Public Employment Service due to the employers' fault, which was corrected when they found out).

At a meeting with the (anti-)Migration Agency after already having begun their medical nurse studies they were told that they had to leave Sweden to apply for a new permit… while in Iran, so they had to pause their studies with university slot reserved for their return this latest October to go to Iran in spite of not having social network and having lost much of the Farsi ("Iranian") language already due to integration in Sweden, but then the Agency decided that naah they had not proven that they really had the intent to study (which they had already begun doing Agency interrupted), so now they are stuck under the mass-murderous Iran-theocracy while their family, father and mother, still live in Sweden.

So, for engineers, scientists or astronauts my brain (I believe) no longer has an automatic expectation for their gender. But apparently for kung fu fighters with weapons it has.

Catching my own unconscious bias in action. The photo below on the cover of a photo magazine was ‘clearly’ a young man training kung fu movements.

Only when starting to read the article I realised that these are women, photographed by the French reporter Fabrice Dimier - see https://www.fabricedimier.com/fr/portfolio/kung-fu-nunns/ for this part of his portfolio.

Ich bin eine Frau, Mutter und Lehrerin. Ich unterrichte Informatik, Astronomie, Mathematik und Politik. Das habe ich alles studiert auf Diplom.
Und ich bin seit über 12 Jahren die IT-Administratorin meiner Schule.

Und ausnahmslos sind es Männer (Lehrer), die mir in meine Position als IT reinreden und diese Position selbst gern haben wollen und mich ständig sabotieren.
Aber: keiner dieser Männer hat eine Ausbildung oder ein Studium in Informatik oder sonst eine gleichwertige Erfahrung in diesem Bereich!

Ich weiß gar nicht mehr, wie es ist, mit Männer über IT zu reden und mich nicht dafür rechtfertigen oder beweisen zu müssen, warum ich tue, was sich tue!
