Last day of a long week at the #TIIME conference at #Nikhef in #Amsterdam. Today is all about #OpenID federations.

Vandaag 10 jaar geleden https://sailing-dulce.nl/home/article-4780 #nikhef #Einsteintelescoop #PhilaeLander Vrijdag 12-02-2016 Ik ben er nog steeds zwaar van onder de indruk, van het nieuws over de detectie van #zwaartekrachtgolven. Opnieuw blijkt Einsteins' algemene #relativiteitstheorie uit 1915 juist. Het wordt gistermiddag om half vijf op twee persconferenties bekendgemaakt, eerst in de VS, daarna bij NIKHEF in Amsterdam. Vierhonderd jaar nadat Galileo voor het eerst zijn telescoop op het heelal richtte en..

Wow! 🤩 Look at this very nice brand-new representation of our #neutrino detector. It shows real #KM3NeT #data from the Mediterranean #deepsea in a huge physical event display in the #hallway of the #Nikhef institute in Amsterdam, The Netherlands
The ladder gives an impression of the height of display.

For those who remember my post from last week. These were "Demo's lasers".

A photo of a person wearing a hat and blue jacket gesturing toward a tabletop laser experiment covered in clouds of smoke, while two children watch and cover their mouths.

Our Tours are Virtual but Demo's lasers are real!

(I saw this on one of the many posters and signs that are being put up for the Wetenschapsdag Amsterdam Science Park 2025 tomorrow. You should visit if you are in the neighborhood!)

A photo showing a part of printed sign with bold black text reads: “Demo’s lasers Virtual Tour &”.

I don't know for sure, but this looks like the traces of students' attempts in cross cultural communication.

In Germany you draw this house to the chant "Das ist das Haus vom Ni–ko–laus.” I don't think there is an equivalent in English?

A photo of a whiteboard with multiple black marker drawings, most are attempts of doing one-line drawings of simple house. Two markers are attached to the board.

A new black hole game (new for me) at our 10 years gravitational waves party at Nikhef.

Yesterday in Amsterdam we marked 50 years of Nikhef. Unfortunately the train strike meant that some colleagues could not join.

Several glasses with black straws sit on a wooden surface. Each glass contains a reddish liquid and contains a floating white label with red text reading "Nikhef 50".

I am happy that my travel companion from the previous post was appreciated. We went to Maastricht, joining a visit (by an EC project officer) to ETpathfinder.

Show your socks!

This PhD ceremony was more colourful than usual. And even colour-coordinated as you can see.

The image shows legs and footwear of people standing on a pavement outside. In the center is a person wearing a pink dress with fur trim and metallic silver stiletto heels. On either side are people wearing black dress pants with pink socks and shiny black formal shoes.

Our group of researchers in Gravitational Waves at Nikhef assembling in a far away location for our annual retreat. I think that soon we will need bigger rooms...

A conference room filled with people sitting on chairs, facing a presentation screen. The room features a crystal chandelier, parquet flooring, and a perforated ceiling. The audience is wearing winter coats in various colors including red, blue, and beige.

Wie das Deutsche Zentrum für Astrophysik das Einstein-Teleskop in die Lausitz holen will

.. Teleskop würde .. mit einem Schlag in eine Wissenschaftsregion von Weltrang verwandeln. Doch die Zeit rennt...DZA-Chef Günther Hasinger .. Denkbar wären für ihn auch kleinere L-förmige Teleskope – auf Sardinien und in Sachsen.

Always a good spot for a photo!

Nikhef is in a festive mood today. We are having a celebration for the outgoing director.

Looking up towards a skylight, three stories up, in the entry hallway of a large building. Seasonal decoration in the form of led lights grouped into stars and spheres are suspended from the ceiling. The building is glowing in golden light, and the skylight is showing a dark blue evening sky.
