Posted in Kids with tags , , , , , , , , , , , , on October 21, 2020 by xi'an

Toute notre communauté universitaire exprime sa plus vive émotion à la suite de l’assassinat de Samuel Paty, professeur dans un collège de Conflans Sainte-Honorine. Nous nous associons pleinement à la douleur de ses proches, de ses élèves et de ses collègues.

En tant qu’université, nos missions prolongent celles assumées par nos collègues de l’enseignement secondaire, dont nous sommes pleinement solidaires. Et nous tenons à rappeler, dans ces circonstances, les principes qui inspirent nos missions d’enseignement et de recherche : le respect de la liberté de penser, le goût du débat, le développement de l’esprit critique, la production de connaissance, tout cela dans le strict respect des lois de notre République.

Patrice Geoffron, Administrateur provisoire de l’Université Paris Dauphine-PSL  & Nicolas Péjout, Directeur Général des Services

“If it had not been for these things, I might have live out my life talking at street corners to scorning men. I might have died, unmarked, unknown, a failure. Now we are not a failure. This is our career and our triumph. Never in our full life could we hope to do such work for tolerance, for justice, for man’s understanding of man as we now do by accident. Our words—our lives—our pains—nothing! The taking of our lives—lives of a good shoemaker and a poor fish peddler—all! That last moment belongs to us—that agony is our triumph.” B. Vanzetti

Today is the 90th anniversary of the execution of Nicolas Sacco and Bartholomeo Vanzetti, Italian anarchists executed in Boston by the State of Massachusetts after an unfair trial. Impacted by anti-Italian prejudice and the radical political views of the accused. Here’s to you is the leading song of the soundtrack of the 1971 movie Sacco e Vanzetti, song written by Ennio Morricone and Joan Baez, also a song I remember singing endlessly in summer camps, as a teenager in the 70’s…

ABC at sea and at war

While preparing crêpes at home yesterday night, I browsed through the  most recent issue of Significance and among many goodies, I spotted an article by McKay and co-authors discussing the simulation of a British vs. German naval battle from the First World War I had never heard of, the Battle of the Dogger Bank. The article was illustrated by a few historical pictures, but I quickly came across a more statistical description of the problem, which was not about creating wargames and alternate realities but rather inferring about the likelihood of the actual income, i.e., whether or not the naval battle outcome [which could be seen as a British victory, ending up with 0 to 1 sunk boat] was either a lucky strike or to be expected. And the method behind solving this question was indeed both Bayesian and ABC-esque! I did not read the longer paper by McKay et al. (hard to do while flipping crêpes!) but the description in Significance was clear enough to understand that the six summary statistics used in this ABC implementation were the number of shots, hits, and lost turrets for both sides. (The answer to the original question is that indeed the British fleet was lucky to keep all its boats afloat. But it is also unlikely another score would have changed the outcome of WWI.) [As I found in this other history paper, ABC seems quite popular in historical inference! And there is another completely unrelated arXived paper with main title The Fog of War…]
