“The meaning of academic publishing is to have researchers talk to other researchers, and to enable that", @danielucko.bsky.social (@apsphysics.bsky.social) says. "If we just have AI models talking to each other, we’re wasting everybody’s time.”

An analysis that sheds light on current issues in scientific evaluation.

"while altmetrics provide valuable insights into the broader digital visibility of research, they should be interpreted as complementary rather than definitive indicators of scholarly impact"

"We began each session by naming a small goal—write a paragraph, put together a figure caption, tackle a tricky transition, or complete some other well-defined task. That 5-minute planning ritual made the rest of the session surprisingly productive."

"there is a big difference between a process that is efficient and one that is valid. As the scientific community starts to embrace AI technology, it must make sure it isn’t solving a logistical problem by creating an intellectual one."

– The elegance of the unexpected –
Scenario: test a new liquid just to see
Ambition: quick comparison
Reality: unexpected behavior… maybe a new thesis topic?
Conclusion: what looks like a failed run is sometimes the start of the next one.

"(...) to be coherent as regards the organisation's stated principles for research evaluation which firstly call for a shift from the use of quantitative bibliometric indicators and secondly for the accelerated development of alternative solutions focusing on open and transparent data."

Wrapping up an inspiring day at @universitedeliege.bsky.social Opening science doesn’t mean sharing everything without limits, it means building a fair, robust and collaborative ecosystem — one that amplifies discovery while managing risks.
“Let’s keep our eyes open to open science”
#OpenScienceDay

scientific image database are never neutral

Stéphanie Derwael reminds us: scientific image #database are never neutral.
They seem complete, uniform, but are curated fragments — selected, organised, normalised.
Every DB reflects choices — critical thinking is key to #OpenScience.

Diamond Open Access model

Jonathan Dumont gave an overview of the “Diamond #OpenAccess” model — free for authors & readers, collectively funded.
Supported by a Belgian foundation uniting actors to improve scientific publishing.
#OpenScienceDay @universitedeliege.bsky.social
#DiamondOA

Mauranne Raskinet’s talk on #AIcrawlers highlighted the exposure of open access data, a reality many institutions now face.
There are leads, but no perfect solution yet — one of today’s #OpenScience challenges.

Gmsh’s code history

Another great moment: Gmsh’s code history visualised like a constellation ✨
Each dot = a code update
Each colour = the status of a part of the code (age, etc.)
A compelling way to make the collective work behind #opensource #software visible.

Meshing applied to aircraft engine noise

Highlight of the day: Christophe Geuzaine’s talk on Gmsh, an #open-source meshing tool 🧩
Break geometry → understand constraints → run simulations
Here applied to aircraft engine noise — a striking example of what open source makes possible.

Gauri, Cheick & Christelle at Open Science Day 2025

At the #OpenScienceDay 2025 at @universitedeliege.bsky.social last week with part of the #Leidenforce team.

A day to reflect together on what openness, transparency and sharing actually change for research.

Lots of ideas to bring back to the office!

Johann Gottlob Leidenfrost: Tribute to a Pioneer in Fluid Dynamics On November 27, 1715, Johann Gottlob Leidenfrost, a German physician and physicist, was born. His observations and theoretical work laid the foundation for understanding the phenomenon now known as the Leidenfrost effect. This... Read more

"The challenge is far more difficult for the vast, messy world of heterogeneous data across the research and development (R&D) enterprise, where varying standards and incomplete metadata create barriers to discovery."

– Experimental method –
Scenario: compare liquids for the #LeidenfrostEffect
Ambition: clean results, sharp table, publishable
Reality: 5 liquids, 3 plates, 0 consistency — vinegar everywhere
Conclusion: If a liquid surprises you, maybe you’re on the right track

In a new study published in Physical Review Letters, Andrea Stöllner, Isaac Lenton, Scott Waitukaitis, and other colleagues have developed a way to catch, hold, and electrically charge a single particle using two laser beams.
