In this issue of Nature (I read on my way to Warwick), a pre-COP30 tribune, to be opposed to later issues!, with a positive take on the impact of the Trump Administration ignoring the conference, with the advances made by China and India (with a surprising 50% of “installed electricity generation capacity coming from non-fossil sources”, if more critical on Brazil’s efforts than the subsequent tribune by the Brazilian undersecretary for ecological transformation for environment, plus a tribune on the ambiguous terms used by countries to secure access to “critical” minerals, in tune with the on-going muscle-flexing attitudes of China and the US. Although the comment is more focussing on the universal access to minerals than to the protection of the workers extracting it and to the environmental impact of it. Followed though by another comment on the climate impact(s) on mining as (no longer) extreme weather events hinder mining all over the (mining) world.

A reflection on China’s 5y plan for science and its reaching a $500 billion annual investment in R&D, predicting (with a large confidence margin) that it will become the #1 power in sciences and technology in the coming decade. I am actually surprised that China has not yet achieved this goal for semi-conductors. And a tribune on the mixed signal of Takaichi Sanae becoming Japan’s first female prime minister, for science as a whole and for gender equity. (My take being that her having UK’s first female prime minister, Margaret Thatcher, as a role-model is not particularly promising. Just like the projection of Marine Le Pen on the verge of becoming France’s first female president does not carry any optimistic message!)

A light entry on a chemical analysis of the specifics of koti luwak (or civet coffee) that does not tell much, beside civet  digestion  adding caprylic and capric acids making beans lower in proteïns and higher in fat. Not yet reaching the goal of “leaving the animals out” from producing this luxury coffee ($75 a cup!).

An article on the shrinking number of US PhD admissions (in some colleges) conflicting with another article in a later issue of a stable influx. And a rather shallow article on the creativity or lack thereof of AI, along with the high sycophancy of LLMs,  to be opposed to a thoughtful reflection on how AI is radically changing the PhD experience and focus, if almost shelving statistics as a thing from the past! But insisting on graduates keeping their ability to check for the validity of their (AI’s)  statistical conclusions!! And another entry on the systematic dismantling of US federal scientific agencies like EPA, CDC, NASA, NOOA, NIH, &tc., by Trump -2.0, which beyond terminating staff contracts in huge proportions is culling the independence of these agencies. With generational impacts on science, training, and evidence-based policies.

A Where I work column featuring a pangolin treated by a Singapore vet, Charlene Yeong. (Unfortunately said pangolin was euthanised after the surgical intervention.) And a book review on the background and motivations of Francis Crick,  just prior to his collaborator James Watson passing away. As noted by the author, Cobb, as MRC staff and later non-resident fellow of the Salk Institute for Biological Studies in San Diego,  “Crick never had to teach or grapple with university administration: he applied for a grant only once in his life.” And concludes that he was not a saint or a hero but “an extraordinarily clever man with limits to his interests and perception”.

all over the moon [or not]

High diddle diddle,
The Cat and the Fiddle,
The Cow jump’d over the Moon,
The little dog laugh’d to see such Craft,
And the Dish ran away with the Spoon.

Read about the cumulated non-sense of a commercial company sending human remains (incl. some DNA of Arthur C. Clarke) to the Moon by a commercial mission, along with NASA scientific experiments, and of the Navajo Nation objecting to it for religious reasons. Wasting energy, time, room (albeit less than 70g) for vanity purposes (at $12,000 per gram) is evidently absurd, almost to the scale of launching a Tesla into space. But such is calling upon religious beliefs to control what can fly to the Moon and what cannot is equally absurd, especially when considering that the whole Moon lander is contaminated with all sorts of material, including DNA. But there may be a dog (on the Moon) since the mission failed.

BoJo’s return to no-future

The [harebrained] proposal of Boris Johnson to return to so-called imperial measurements or units illustrates [beyond his usual flair for spinning out of yet-another-scandal] an all-too-common innumeracy of politicians (and possibly a lingering anti-French sentiment as metric units were introduced by the French Revolution), preferring to cater to their Brexit voters rather than realising the drawbacks and costs of a parallel system of measurements, as illustrated by the 1999 Orbiter crash. Does he plan to exit the Bureau International des Poids et Mesures as well?! Or does he expect an improvement in numeracy with the public using different bases (other than 10) at ounce once?!

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.]
