Cartes et espaces
L’agence fédérale ICE, aux USA, mène actuellement une campagne de déportation voulue massive. Ses effets concrets suggèrent toutefois que son but serait aussi, voire surtout, d’intimider les opposant·e·s politiques du président Trump. Une comparaison des cartes électorales avec celle des activités ICE corrobore cette hypothèse.
Notons en préambule que la carte est compilée à partir de données hétérogènes à l’aide […] Continue Reading…
OUROBOROS TREE is a visual application for exploring relations between human nutrition and living organisms. I have built it because many contemporary issues can be addressed through a prism of our relationship with “non-humans” (according to Bruno Latour’s terminology). The project is evolving and welcomes feedback from the public.
OurobosTree harmonizes, for the first time, environmental and nutritionist data from […] Continue Reading…
A long-term timeline of technology by Max Roser
A couple of days ago, I stumbled on LinkedIn on this image showing a long-term timeline of technological development by Max Roser, founder of Our World in Data.
The graphic is impressively synthetic, and deals beautifully with exponential time scales, both prior and after the modern epoch.
But I am not convinced that […] Continue Reading…
I rarely travel by plane but, when I do, I can’t help checking that little screen of bad LEDs at least five times an hour, to see the map of locations miles below. Many of them I’ve never heard of, and most of them I’ll never see. Their names appear on the screen like as many alchemic ingredients: Athens, […] Continue Reading…
“Zeroworld”, a recent episode of the WNYC podcast Radiolab, examined the possibility of division by zero. The discussion turned mostly metaphysical and got many listeners so angry that they went on to rant on Reddit. I understood this episode more as a fun thought experiment than as a formal proposal. But it also reminded me of some of […] Continue Reading…
LaTeX started as an ASCII thing for English speaking nerds. Only later did people start to use it all over the word, in many languages from Cezch to Hindi. We now have XeTeX and LuaLaTeX. But like the serpent Sesha in the Hindu mythology, some of that early ASCII universe remains, notably in the BibTex part of things.
BibTeX […] Continue Reading…

I wondered how it would render on polar coordinates. So I made an R script to do so. The script is reusable for other data sources as I show below. So reuse, enjoy, and make useful.
The plotting function
seasonplot <- function(tsdata,maintitle,source,legxleft,legxrigth,legytop,legybottom) {

This blog entry is work in progress… Please be patient, more content is comming soon. Meanwhile, you can read other posts.
Concepts are encoded in most artworks, at least in all that make it to the museum and visiotors bother to see and acedmics to write about. I focus here on major examples.

Railway track gauge in Eurasia and North Africa. Source: openrailway.org
A look at the global map of rail track gauges immediately reminds you of the current invasion of Ukraine. There is a material substrate of the putinist nostalgia of the Muscovite Empire. Far more than a purported linguistic or cultural proximity of the ex-Soviet states, this substrate of steel […] Continue Reading…
I’ve had the pleasure to write a foreword of the French translation of Ananyo Bhattacharya’s biography of John von Neumann, translated by Anatole Muchnik and now published by Quanto.
You can read the French introduction and have a peek at the book’s first chapter (PDF).
In agreement with Ananyo, here is the English translation.
As you read the biography of […] Continue Reading…
