Wanted to try the too good to go from the Polish place for ages. Very fun (one of the donuts is missing, I ate it on the way)! There is definitely some truly weird stuff in here, not sure what to do with the fish in the glass 😳

It's a pickled (=preserved) Brathering, you can obviously also get that fresh. But only close to the coast.

I do like the pickled version once in a while.

If 30ml of ink printer ink cost 15€, why does this 20 cubic meter truck not have a police escort?

Today I'll be introducing X-ray astronomy (in German!) to a bunch of medical doctors at the RöKo (Röntgenkongress https://www.roentgenkongress.de/roeko-wiesbaden/) Wiesbaden as an invited highlight talk. Kinda a fun audience and very different from a normal one 😳

Ich kann Dir sagen, dass man mit kosmischen Röntgenstrahlen zumindest die Struktur eines Satelliten abbilden kann, wenn man Löcher im Schutzschild lässt. Z.B. die Kabel und Stecker der Solarzellen.

I am trying to re-create an old talk from ~4 years ago I found in my archives and I simultaneously love past-me (she did such a great job developing a talk structure, much better than the one I had in mind when asked to give a talk on this topic a month ago!) and hate her (she somehow managed to deleted the keynote of the talk so that I am now stuck with a PDF and trying to find all figures & re-type the text ...).

knud,
@knud@mastodon.social avatar

@vicgrinberg

Can you convert PDF to Keynote with some tool? Or is that so ... limited that re-creating it from scratch is easier?

knud,
@knud@mastodon.social avatar

@vicgrinberg

Then happy "creating". I was amazed which level of detail is actually preserved in a PDF unless the exported resolution was substantially reduced. Full pictures even underneath masks, etc.

But if you have most of the original pix then it's definitely easier.

I finally put an animated observation from 2018 onto , where I observed the Moon one evening and then again the next morning. With a ~7000km baseline due to the Earth having rotated with me on it, the Moon appears under an angle differing by ~0.5°. That is "diurnal libration":

Is that how actual streaming studios look like?

knud,

@vicgrinberg

I was already googling "pro streaming cam" and "LED light panel"...

knud,
@knud@mastodon.social avatar

@vicgrinberg

Yep, I have that impression from some streamers, there are so many people behind the scenes...

This was my "studio" for a talkshow/talk with @hausderastronomie - while I was traveling. The backdrop was locally printed and stitched together with sellotape. :-)

knud,
@knud@mastodon.social avatar

@vicgrinberg @hausderastronomie

I bought that during March 2020... I also have a greenscreen. I could use a better camera and some extra light panels.

I contemplated if we shouldn't have a Euclid "monthly update" or so.

These unofficial Mastodon accounts of space agencies are bots that merely share news items the agencies publish elsewhere, yet the accounts have quite a lot of followers:

  • NASA: @nasa 71K followers
  • ESA: @esa 1.4K followers

There's an unfulfilled demand for public institutions to communicate on open and independent platforms.

I have to talk to ESA again about this. We asked about a move or at least starting activities in the Fediverse, but they didn't have any final discussions on this yet.

“The cats were found dead with no apparent signs of injury and were from a resident population of ≈24 domestic cats that had been fed [unpasteurised] milk from sick cows. Clinical disease in cows on that farm was first noted on March 16; the cats became sick on March 17, and several cats died in a cluster during March 19–20. In total, >50% of the cats at that dairy became ill and died.”

Erinnern wir uns an die Proteste gegen den AfD Landesparteitag am 20.04. (!!!) in Niedersachsen in Unterlüß:

  • Drei Züge in Richtung Unterlüß wurden aus „technsichen Gründen“ gestoppt oder verspätet.
  • Ein Zug wurde angehalten, die Polizei hat alle zur Demo anreisenden durchsucht.
  • Menschen die bei der Demo auf dem Boden saßen um zu frühstücken wurden zufälligerweise ausgesucht und von der Polizei geboxt.
  • Es kam die Anweisung an die Polizei kein Pfefferspray oder Sonstiges zu benutzen sondern sofort den Schmerzgriff und Prügelei anzuwenden.

...und es hat sich trotzdem gelohnt weil die AfD den ganzen Tag unterbrochen wurde und nicht friedlich ihren Unsinn durchführen konnten.

Jede Person die in Unterlüß dabei war weiß wie sehr der Staatsapparat jetzt schon den Faschismus stützt. 20% der Menschen im Land wählen die AfD, die Polizei ist generell mehr rechts, die dortige Verteilung mag also schlimmer sein!

Fazit: zum AfD Bundesparteitag in Essen (28. - 30. Juni 2024) wird ausschließlich mit Bussen angereist! 🚌

This week, we're hitting the #Blender3D shop floor for a big design that (I hope) will ultimately become a #VR space for a conference.

So far... it's a doughnut.

Is this to remind attendees that they better getting running around this track to burn off eating too many pastries? We shall see...

@elizabethtasker

Pleeeease keep us posted about the final product, the path to get there and the user experience during the meeting.

We have a paper coming out tomorrow (in PNAS Nexus) on the CO2 emissions of all astronomy conferences in 2019. They're immense and not sustainable in the future and as a depedency for communication of the field.

knud,
@knud@mastodon.social avatar

@elizabethtasker

I will and yes. This started as a small product in A4E and took very long to get all data (and equally long to get it into a journal). We assessed all astro conferences and schools globally (~300 with specific data, the remaining ~60 with extrapolation).

€122 for the best timed TGV train to Paris €97 is the cheapest
Cheapest flights from €43

I've had it twice last year that the only (!) connection from Barcelona that still let's me travel onward to Germany was sold out. In both classes. Sucked big time. It all depends on too few seats on a single train.

    Autonomes Fahren in Städten ist tot. Aus, vorbei. Das hat Apple erkannt, das hat Bosch erkannt, das hat vermutlich auch Tesla erkannt, darf es aber noch nicht laut sagen.

    Und ich bin froh darüber, weil klar war, dass das wenn dann nur mit massiven Einschränkungen (oder Gefährdungen) aller anderen Verkehrsteilnehmer*innen hätte funktionieren können.
