vous vous êtes fait avoir de 0,00159265359 et quelques! sinon très beau!

je viens de le mettre dans ma liste :-) manque plus qu'une occasion.

je veux bien un RETEX sur le menu qui effectivement fait envie!

it is easy to get lost in details and lose the big picture (and never get anything done), and conversely it is easy to have a grand idea which is totally infeasible because details don't add up.

A strong quality for a good researcher is the ability to sometimes ignore small details, and sometimes delves into them with the greatest care, and more importantly to being able to switch wisely between the two modes.

very honored to give the opening lecture tomorrow at the NNV AMO meeting in Egmond aan Zee (NL). Very curious to see what happen if -probably- the Physics prize is announced during my lecture (probably nobody will pay attention to the second half of my lecture).

a national treasure of french science!

🔬For 22 years, we have been organizing #Mifobio "Functional Microscopy for Biology" the @cnrs.fr thematic school.

🎓 Courses, Seminars, Round Tables, Workshops. The overall theme concerns #biological_imaging in its most interdisciplinary aspects.

👉 Program: imabio-cnrs.fr

Very happy about this one, a great work by Baptiste Courme, and an old dream coming true : we can demonstrate a violation a Bell inequality just by sampling random polarization states from speckle field.

"Harnessing Optical Disorder for Bell Inequalities violation"
a joint work with Hugo Defienne's team.

In short : a speckle essentially has a random polarization state at any position, we exploit this to show we can violate a BI.

Hi Aephraim, paper looks super interesting, and I will read it in details - I wonder if there is any link with the invariance of the dwell time we studied in www.pnas.org/doi/abs/10.1... which is also ultimately linked to Wigner time-delay and Weyl law. would be happy to have your opinion.

This is the end of a short visit to ETH Zurich, I was very intimidated to visit the math department (as an experimentalist) but it turned out great, thanks to my host Habib Ammari. Also great to (re)connect to colleagues in Physics, Mechanics & engineering, and enjoy a nice Picasso exhibition.🇨🇭🧀🍫

Well hidden in a small corner of the main building of ETH Zurich, they have made a mini museum for Einstein in his former locker 😍

If you have a sister or a mother in science, I’m happy to discuss a collaboration 😛
sylvaingigan.bsky.social
Definitely a challenge in physics, but yes, will try !

I am a family-friendly scientist:
✅ I have published with brothers (several pairs, joint papers)
✅ I have published with father and son (separate papers)
✅ I have published with husband and wife (separate papers)
not sure what's next 🤣

j'ai eu une fois la reservation de voiture (par N...), annulée 30 minutes avant que je prenne le vehicule. Bilan : prix x3.

unfortunately I was not the reviewer this time, I could just witness the result.

#PetPeeves incremental papers in high-impact journal that cites the really novel work they are based on (usually published in a solid but more obscure journal), but in such a convoluted and obscure way that the editor and reviewer's don't realize it's incremental.

you are the gem of our program :-)
