A personal tribune (by a Vatican advisor) on why scientists should learn from the Pope’s AI message, not the first time Nature caters to religious views! Not that his (Leon’s) concerns about unregulated AI and the abdication of States in that matter are misplaced. But it seems unlikely (as the author concedes in his conclusion) that the Catholic Church or his leader will manage to make a dent on the spiraling impact of AIs. As suggested in the next tribune, a coordinated approach at a massive increase of taxes on tech companies (unsurprisingly resisted by the Orange Menace) is more likely to happen. And yet another tribune on AI and math(ematician)s, related to the recent Leiden Declaration on Artificial Intelligence and Mathematics, following several entries in the previous issue.

An introductory (general public) article as to why cancer occurrences in young people is rising so quickly in the US, with no single explanation. Environmental factors are certainly to blame, like the consumption of ultra–processed foods, but the article does not say much, adding to the uncertainty.

A rather unhelpful representation of human migration in 2023, appart from showing a majority of migrations are local (to the continental scale). Connected to an article of 10 June I missed. Partly based on a deep learning model to achieve a country-level granularity.

A research article (and the cover) on a plague outbreak near Lake Baikal—over which I could have flown when reading this issue, except that flights to Japan now contour the territories of the invader of Ukraine—that occurred about 5,500 years ago and impacted a community of hunter-gatherers, In a sparsely populated area, marmots being the likely primary vectors, and a close phylogenetic proximity to current strains.

“Peace requires before all else the defense of life, a good that today is jeopardized…through the promotion of an alleged ‘right to abortion’. No one, however, can claim rights over the life of another human being, especially one who is powerless and thus completely defenceless.” 09 Jan.

“I would like to emphasize one thing: It is very important that we have this meeting, this meeting between men and women, because today the worst danger is gender ideology, which erases differences.” 01 March

“A woman within the People of God is a daughter, a sister, a mother. Womanhood speaks to us of fruitful welcome, nurturing and life-giving dedication”. 28 Sept.

“On my return to Rome, I will open the process for the beatification of King Baudouin. His example as a man of faith may enlighten those in power. [I praise] the courage of this man who chose to leave his position as king in order not to sign [the 1990 abortion] law.” 28 Sept. (International Safe Abortion Day)

“I have no way of telling whether [Putin’s] rage has been provoked»” Bergoglio wonders, «but I suspect it was maybe facilitated by the West’s attitude” [“Un’ira che non so dire se sia stata provocata — si interroga —, ma facilitata forse sì”]

“I don’t know if it is the right thing to supply the Ukrainian fighters” [” all’interrogativo se sia giusto rifornire gli ucraini”]

“What seems indisputable is that in that country both sides are trying out new weapons. [” La cosa chiara è che in quella terra si stanno provando le armi.” Corriere Della Sera, 22 Maggio 2022]

“This is a historic day in the life of our country, one that stirs our thoughts, emotions and prayers. For nearly fifty years, America has enforced an unjust law that has permitted some to decide whether others can live or die; this policy has resulted in the deaths [sic] of tens of millions of preborn children, generations that were denied the right to even be born (…) We thank God today that the Court has now overturned this decision.” U.S. Conference of Catholic Bishops, 24 June 2022

quick(er) calculations [book review]

Upon my request, Oxford University Press sent me this book for review in CHANCE. With the extended title How to add, subtract, multiply, divide, square, and square root more swiftly. This short (173 pages) book is written by Trevor Davis Lipscombe, currently Director of the Catholic University of America Press (which are apparently not suited for his books, since his former Physics of Rugby got published by Nottingham University Press). The concept of the book is to list tricks and shortcuts to handle seemingly tough operations on a list of numbers. Illustrated by short anecdotes mostly related to religion, sports (including the Vatican cricket team!), and history, albeit not necessarily related with the computation at hand and not providing an in-depth coverage of calculation across the ages and the cultures. While the topic is rather dry, as illustrated by the section titles, e.g., “Multiply two numbers that differ by 2, 4, 6, or 20” or “Multiply or divide by 66 or 67, 666 or 667” (!), the exposition is somewhat facilitated by the (classics) culture of the author. (I have to confess I got lost by the date chapter, i.e., finding which day of the week was December 18, 1981, for instance. Especially by the concept of Doomsday which I thought was a special day of the year in the UK. Or in the USA.) Still, while recognising some simple decompositions I also used for additions and subtractions, and acknowledging the validity of the many tricks I had never though of, I wonder at the relevance of learning those dozens of approaches beyond maintaining a particular type of mental agility… Or preparing for party show-time. Especially for the operations that do not enjoy exact solutions, like dividing by √3 or multiplying by π… The book reminded me of a physics professor in Caen, Henri Eyraud, who used to approximate powers and roots faster than it took us to get a slide rule out of our bags! But Guesstimation, which I reviewed several years ago, seemed more far-reaching that Quick(er) calculations, in that I had tried to teach my kids (with limited success) how to reach the right order of magnitude of a quantity, but never insisted [beyond primary school] on quick mental calculations. (The Interlude V chapter connects with this idea.)
