Here is video of 1st lecture at College de France on Biological computation 😊. I defend the necessity to access Algorithmic & Computational levels of analysis in cell & dev. biol. proposed by David Marr in neuroscience. Logic & Function matter 🤩.

Le colloque de rentrée sur l'animal que j'ai organisé au Collège de France est désormais en ligne. Retrouvez notamment mon introduction au problème animal (college-de-france.fr/fr/agenda/coll…), ainsi que ma conclusion (college-de-france.fr/fr/agenda/coll…). Je montre comment l'ambiguïté même du mot « e d'une porosité avec l'être humain. Les pronoms interrogatifs, en français comme en anglais, empêchent de reconnaître aux animaux une position de sujet. Au bout du compte, penser l'animal, c’est aussi interroger nos propres pratiques, nos modes de vie et les choix éthiques auxquels nous sommes quotidiennement confrontés. C'est une question de responsabilité.

Beautiful Paris by night … 🤩

100 years old. Still the sharpest mind in the room.

Jean-Pierre Serre, youngest Fields Medalist in history (age 27), first Abel Prize winner, and the “Mozart of mathematics,” turned 100 on September 15 and is still lecturing, still writing on the blackboard, still shaping the the greatest living mathematician. The rest of us are just trying to keep up.

An expert is a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field.

-- Niels Bohr,
quoted by Edward Teller (1954)

If you want to know whether a system is being driven or at equilibrium, you need its probability current.

Getting this from actual dynamical trajectory data has been the hard part.

To help solve this I've been developing a
Delaunay-Voronoi Fokker-Planck (DVFP) instrument.
irregular, time-ordered phase-space observations into an empirical Fokker-Planck description.

The distinction is simple:
Geometry tells us what is nearby. Time tells us what happens next, and these are handled properly in this construction.

From here we obtain density, drift, diffusion, and probability current, which is what detailed balance and entropy production are built from.

Paper and DOI: doi.org/10.5281/zenodo…

Animation: As the underlying dynamics evolve, the DVFP instrument adapts its local weighting while preserving the temporal ordering of the observations.

A very thoughtful lecture, unsurprisingly, by @pgodfreysmith He’s a pretty good neuroscientist for a philosopher :-)

I've just started my 2nd lab at RIKEN BDR in Kobe, Japan!

This small, focused group will compare and manipulate species-specific time and shape, in collaboration with our Dresden lab.

La nouvelle est passée presque totalement inaperçue dans les médias français, en raison du Mondial de foot et des incendies : l’intelligence artificielle a réussi à déchiffrer entièrement un rouleau de papyrus carbonisé d’Herculanum, aussi fragile que de la cendre de cigarette, s même y toucher ! On y a découvert un traité philosophique sur le stoïcisme. Il a fallu des trésors d’ingéniosité et de technologie pour parvenir à ce résultat. Le rêve est donc devenu réalité : bientôt, on pourra lire en un temps record les centaines de rouleaux de cette bibliothèque calcinée par le Vésuve il y a 2000 ans, et la littérature gréco-latine s’enrichira d’autant de textes inédits, de nouvelles tragédies ou épopées peut-être. Dans cet été déprimant, voilà un vrai rayon de lumière. Vive la science !

An auspicious day, today, 14 July for a semi-final 🇫🇷. May the better team win!

We just celebrated with alumni & current members the 25yrs anniversary of our group @IBDM and @centuri_ls. Lots of joy to witness the scientific paths of so many talented ex members. Big smiles, laughs & fun 🤩. So thankful for having had such colleagues. Let’s keep going 😊

It was wonderful to host Mukund Thattai from @NCBS_bangalore to give a seminar @centuri_ls. Thank you for entertaining us on how information is encoded at the cell surface. 🙏🏼

Registration for 𝐂𝐄𝐍𝐓𝐔𝐑𝐈 𝐒𝐜𝐢𝐞𝐧𝐭𝐢𝐟𝐢𝐜 𝐌𝐞𝐞𝐭𝐢𝐧𝐠 𝟐𝟎𝟐𝟔 are still open!

Visiting Duke Univ. yesterday. What a treat to be hosted by Akankshi Munjal (former PhD std) 🤩 and spending time with fantastic trainees & wonderful faculty, such as
Stefano di Talia. Many thanks for the invitation 🙏🏼. A place full of talent & energy.

Many thanks Nicoletta Petridou @petridou_ni from @embl Heidelberg for visiting us @centuri_ls and giving a truly exciting talk on cell division timing and phase transition during embryogenesis 🤩! Developmental biology is really cool 😎

En sa belle jeunesse, en sa première fleur,
Rendre le ciel jaloux de sa vive couleur,
Quand l’Aube de ses pleurs au point du jour l’arrose »
