Nature snapshots

In this 15 March issue of Nature, a rather puzzling article on altruism that seemed to rely on the Hamilton rule:

linking fitness and number of offspring and benefits through kth-order moments. In a stochastic environment represented by distribution π. Hard to fathom what comes from data and what follows from this (hypothetical) model. Plus a proposal for geoengineering meltdown delays on some Greenland and Antarctica glaciers. Scary. And a film review of Iceman (Der Mann aus dem Eis), retracing Ötzi’s life in an archaeologically acceptable rendering. Including a reconstituted local language, Rhaetic.

March(es) for Science

Posted in Statistics with tags , , , , , , , on April 22, 2017 by xi'an

Today there are around 500 marches for Science organised around the World (incl. on in Kangerlussuaq, Qeqqata, Greenland!). Primarily to protest the unprecedented attacks of trumpism on science, scientific values, and scientists, and not only through budget cuts, agency closures, public data erasures, but also denegation of scientific expertise and data to advance financial and partisan interests against climate, water preservation, minorities rights, women equality, and international relations. Being now at a remote retreat in Northern Wales, I will walk virtually at the Cardiff March for Science.

IMG_2181On my way to Duke and O’Bayes 2013, I took an early flight to Atlanta, with a bit of a delay because of a faulty tractor in Charles de Gaulle airport but all in all an overall smooth trip. We alas flew too much south this time to get any view of Greenland except for the glimpse below… Apart from working on my slides for today’s lecture, I watched bits (actually most) of rather silly films, The Lone Ranger and Oblivion, not really worth reviewing here. (The former is playing too much on second degree references to Pirates of the Caribbean. From Johnny Depp making faces to his playing with his watch, to the recurrent madman wearing women’s clothes and playing with an umbrella. The second one was just appalling, from the abysmally poor acting to the ultimate absence of a plot…) I also read in The NYT about a new super-prize in Mathematics to be launched by a few “philanthropists”, including Mark Zuckerberg. The paper was not giving any detail on the focus of the prize and on the motives of the generous donators. Interestingly, the similar prize they set for physics went to two proponents of string theory, which is still a mathematical construct with no experimental evidence, as far as I understand…IMG_2176Rereading Johnson’s PNAS paper for my tutorial had the side result of making me realise him using a flat prior on a normal mean without more justification than there is a “constant factor that arises from the uniform distribution on μ”…
