A nice cover (and a used pun) on the cover of this issue of Nature. That (reminded of trees from the Guadeloupean rainforest and) which refers to the rich microbiomes found in trees, with a partition between sapwood and heartwood. Along

  • an editorial call for “hazardous” research, namely the relevance of studies on urban gullies that endanger surrounding populations and have unpredictable dynamics, albeit scientists alone cannot provide solutions.
  • a Columbian study on how the microbial communities acting during the fermentation of cocoa and could be controlled towards finer chocolat).
  • the alas now usual articles on the impacts of Trump.2.0 on science and academia, with US Minister of Health Kennedy launching a call for finding the environmental cause of autism. When most researchers blame primarily genetics and associate the rise in cases with a rise in detection and awareness. And pointed out at the earlier drop in NIH funds for autism research, the overall balance being negative.
  • plus a useful debunking of five quantum theory myths! Along with the story of a 2020 Science paper by Vaitiekėnas et al. on Majoranas that raised enough questions for Science to publish an expression of concern, now lifted after the publication of a long correction.
  • (a video of) rappelling robots diving into a lava tube!!
  • a Verne-esque proposal to create a lunar biodepository, a (dubious imho) mix between Noah’s Ark and the (unscientific) faith in cryogeny
  • a more sobering call for more frequent data inputs (forcing datasets) to calibrate climate models, with no mention made of statistics or machine learning…
  • an operative “mind-reading” device… with a protection password (and a 74% efficiency)!
  • two research articles on AI unification of cognitive theories.
  • Another one on the (revolutionary) construction of an optical encoder-decoder network towards generating images.

the calculating stars [book review]

Posted in Books, Travel with tags , , , , , , , , , , , , , , on October 16, 2021 by xi'an

This fist sounded like an interesting attempt at alternate history, when a massive meteor strike obliterating the Washington DC region in 1952 forced the World to change shift towards space exploration and the eventual evacuation of Earth. The story is told from a computer (or computress) viewpoint, who is a wunderkid, a mathematician, a physicist, a war (WASP) pilot, and more, with a strong will and an independent mind, hoping to become a female astronaut. If the setting reminds you of Hidden figures, a (great) movie about the true story of NASA black female mathematicians, it is no surprise and I wonder how much inspiration the author got from these historical facts, if not from the 2016 book itself. Despite receiving many awards, like the Hugo, Nebula, and Locus awards!, The Calculating Stars is somewhat of a disappointment to me, because of the highly single-minded perspective,  where everything (related to solving the forecast extinction) seems to happen with a small group of people, because of the confusion between a mathematician and someone who can do complex arithmetics by head, to the near-perfection of the central character, who can also hotwire a car, because of the anachronisms, incl. the prescience that the asteroid crash was going to cause a deadly rise of temperatures when the dinosaur extinction was not yet linked with a similar event, because of a rosy depiction of the World uniting towards racing against the Great Extinction, and, cherry on the pie, because French sentences found throughout the book mostly make no sense as literal translations of English sentences!

“Elle va le faire mais Dieu sait ce qu’elle va parler.” [She’s going to do it but God knows what she’s going to say.]

“Il est l’ordre naturel je pense (…) Il n’y a rien de naturel.” [It’s the natural order of things I think (…) Nothing is natural.]

“Ce ne fut pas une explosion ou nous aurions senti.” [It wasn’t a blast or else we would have felt.]
