Un slide que j'aime bien montrer

"Scientific authorship is a two-sided coin. Credit goes hand in hand with responsibility, which is essential for transparency and maintaining trust in science. That responsibility includes acknowledging when things don’t go right."

The Leidenfrost effect: when drops levitate Water droplets can levitate on hot surfaces thanks to a vapor layer. Learn how in this @espciparispsl.bsky.social MOOC video. 🎥 www.youtube.com/watch?v=keKF... #LeidenfrostEffect #Droplet #FluidDynamics #ScienceResearch #MOOC

"What we know is nothing compared to what we don't know ; and the distance between the man who knows the most and the man who knows nothing is not as great as is generally believed." Pierre Hippolyte Boutigny, Studies on Bodies in the Spheroidal State – A New Branch of #Physics (1857) #Knowledge

“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.” #PeerReview #GenerativeAI

"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" #Altmetrics #ScholarlyImpact #ResearchEvaluation #ImpactFactor #ResearchMetrics

"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." #AcademicWriting #PeerGroup #PhD #BlankPage

"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." #AI #AIReviewers #Feedback

LAB CHRONICLE #28 – 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. #Physics #HopeInTheLab #GoodDay #Test

"(...) 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

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. #OpenScienceDay @universitedeliege.bsky.social #DataBias

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. #OpenScienceDay @universitedeliege.bsky.social #WebScraping #DigitalRisks

The “10 lessons learned” from developing Gmsh. Practical tips for creating #OpenSource software. #OpenScienceDay @universitedeliege.bsky.social #ResearchTips #BestPractices #OpenScienceTips

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. #OpenScienceDay @universitedeliege.bsky.social

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. #OpenScienceDay @universitedeliege.bsky.social #Dev #FOSS

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! #OpenScience
