Found this beautiful beetle in the garden

The photo I should show when people ask me what worklife @nikhef.bsky.social is like

Sat under a tree today while listening to a talk about dark matter detectors @nikhef.bsky.social

#commuterlife #trainstation #amsterdam

Nice interactions during the social media session at the @nikhef.bsky.social Jamboree. Thanks to @tristandupree.bsky.social @koppenburg.ch and @particleclara.bsky.social

It may not look like much, but a few months from now this could be a thriving vegetable garden.

More beautiful @nikhef.bsky.social technology! You are looking at a segment of the molecule decelerator for the eEDM experiment in Groningen, used to study the electric dipole moment of electrons.

What many of us at the Einstein Telescope Organisation (ETO) will be working on...

Work has begun on a site-independent report comparing Einstein Telescope geometries: a triangular design vs. a dual L-shaped design. The analysis covers five aspects: scientific added value, risk, costing, governance, and socio-economic impact. Read more: einsteintelescope.eu/news/towards...

ETO and ESA have launched a collaboration on cost estimation for the Einstein Telescope, formalised in January 2026. A meeting at ESTEC on 24 March marked its strategic start. Read the interview: shorturl.at/rjnUo #EinsteinTelescope #ESA @technology.esa.int

New spokesperson + deputy spokesperson for the scientific collaboration of the #EinsteinTelescope

Looking at Timepix chip technology, used for detecting particles. Developed @cern.bsky.social and @nikhef.bsky.social

Struggle to think of female scientists? It’s in the stories we tell. Or don’t tell. On International Women’s Day, Robert McNees shares stories about women who deserve more spotlight than they got:

Sprouting apple branches announcing spring...at least indoors.

Feels like yesterday, but today it's already 7 years ago that @maastrichtu.bsky.social joined @nikhef.bsky.social ! Not the best picture...but I was there ;).

Mirror eyes...or a module for a giant neutrino detector at the bottom of the Mediterranean Sea @km3net.bsky.social , @nikhef.bsky.social

Sometimes train problems turn into a treat! And I am not just talking about the coffee and croissant. Finally I had the space and time to calmly read through a report I had been carrying around with me for some time. #einsteintelescope #einsteintelescopeorganisation

Today, 11 February, #GW stands for two things: #GravitationalWaves 〰️ and #Girls&Women ❤️. We mark 10 years since the first GW detection announcement (11 Feb 2016) and the International Day of Women and Girls in Science. Both began in 2015 (GW150914). ✨

🌟 Why ET goes underground: to escape surface noise (incl. Newtonian noise) and detect incredibly faint #gravitationalwaves. New article: facility concept, safety, and what it’s like to work below ground. Read: lnkd.in/dwweVX29

Einstein Telescope infrastructure & safety depend strongly on the future site 🗺️🛡️. On 19–20 Jan 2026, ETO, candidate host consortia and CERN met to exchange key info 🤝, with additional experts joining online 💻 @cern.bsky.social

Altijd al een kijkje willen nemen bij de versnellers en detectoren van CERN? Op maandag 26 januari 13:30 uur leidt Nikhef-masterstudent Niels ter Linden in een live verbinding www.youtube.com/@Nikhef toeschouwers rond bij het ATLAS-experiment op CERN. www.nikhef.nl/evenement/li...

Apparently it's blue Monday... doesn't look too bad through these blue frames

A check-in moment🤝: Einstein Telescope Organisation and CERN met to align on shared objectives for ET. From vacuum and materials to manufacturing, civil engineering and safety, CERN’s engineering expertise supports key ET activities — and opens the door to powerful synergies✨.

A peek into the future #EinsteinTelescope @nikhef Amsterdam. Model by @mjkraan.bsky.social

Couldn't attend the #einsteintelescope collaboration's annual meeting, but I wasn't forgotten! A postcard arrived for me in the office. @einsteintelescope.bsky.social

Magical moment on the train this morning: at some point there were more people around me reading books than people looking at their phones. It lasted a lovely fifteen minutes. #forenzenleven

Wires @nikhef.bsky.social in Amsterdam.

Missed the 7-year mark, so today I celebrate working at Nikhef and for the Einstein Telescope for 7.5 years! 🎉.

Just some beautiful gravitational wave detector technology. @nikhef.bsky.social

Workday #haiku: Power dress today Or is my inner power in wearing flowers

Happy International Day of LGBTQIA+ People In STEM! How are you celebrating it? #LGBTQSTEMDay #PrideInSTEM

Apparently yesterday was EU Equal Pay Day. In NL it's supposed to be on 24 November(?). Thought exercise: what if all women started their end-of-year holidays right now...

Thursday thought: meetingless Mondays should be a thing. Best way to start a work week for me: time for some focus and deep work with a fresh mind.

Some November flowers to brighten up this Tuesday

Trying to proofread using AI today, but it first suggests to change things...and when I accept the changes and check again, it suggests to change it back. Not convinced yet....

In case you missed it: the Dutch Network of Women Professors (LNVH) published a report on future-proof & more inclusive academic management. A highlight: formalised and transparent appointment procedures are crucial for fair access to management positions www.lnvh.nl/a-4082/lnvh-... #womeninscience

Thursday thought: Marketing has the '4 p's'. Communication in science is often limited to 4 other p's: Powerpoints (or other slides), Papers, Posters and Pints (or coffees). Alright, and may be an 'E' for Email. Still limited. Happy to be part of the movement that is pushing to move beyond this.

More apples from the garden...

The most special apple I have ever held. It was many years (probably ~9) in the making. Turns out it is possible to grow an apple tree from seed and get apples 😍.

💔 A legend.

Tijdens de A'dam Science Park Wetenschapsdag as. zaterdag kun je o.a. aansluiten bij een rondleiding naar de productiehal voor @km3net.bsky.social. In februari waren zij overal in het nieuws met de detectie van een neutrino met de hoogste energie ooit! wetenschapsdagamsterdamsciencepark.nl/nikhef/

Back at Nikhef Amsterdam after working in/from other places for a few weeks. Feels a bit like coming home (hope my plants are still alive 😬).

Impression of a workshop during the general meeting of the Einstein Telescope Organisation (ETO) this week. Look at these colleagues + friendly guests to keep us sharp, with their brains buzzing over an article for a (semi-internal) newsletter we are setting up. #einsteintelescope

Photos! This is the job assigned to me for today. Should be fun! #photography #einsteintelescope

It was a good day, full of useful meetings and sessions. Now it's time to unwind. (Working on further building the #einsteintelescope Organisation (ETO) during our general meeting at Elba this week)

On board for several days of Einstein Telescope Organisation building. (It seems Elba is kind of the Italian equivalent of Terschelling) #einsteintelescope

Someone is trying to blend in.

Oh dear, may be I ordered some props for an upcoming workshop again...

Designing the future underground #EinsteinTelescope is a process of many stages and refinements. A taskforce has now worked on a new integrated baseline design. Read more: einsteintelescope.eu/news/towards... @einsteintelescope.bsky.social
