“Bisogna dire la verità agli italiani: senza immigrati l’Inps crollerebbe. Chiudere le frontiere significherebbe una manovra economica in più ogni anno. Se i flussi di entrata dovessero azzerarsi, avremmo per i prossimi 22 anni 73 miliardi in meno di entrate contributive e 35 miliardi in meno di prestazioni sociali destinate a immigrati, con un saldo netto negativo di 38 miliardi per le casse dell’Inps”.
Queste le parole pronunciate dal presidente dell’Inps, Tito Boeri, durante la presentazione del rapporto annuale dell’Istituto avvenuta ieri a Montecitorio. Ecco una di quelle notizie che dovrebbero campeggiare sulle prime pagine di tg e giornali. Pregiudizi, stereotipi, fake news si combattono anche e soprattutto con una informazione corretta.

Il Salgari dimenticato (sci-fi) e i suoi illustratori (pure)
Nella sua vasta produzione Emilio Salgari ha scritto anche romanzi di protofantascienza e molti illustratori hanno dato vita al quel mondo immaginario.
Un documentario svedese su New York girato nel 1911 è una eccezionale testimonianza della vita nella Grande Mela prima della Prima guerra mondiale
Money quote: "Produced only three years before the outbreak of World War I, the everyday life of the city recorded here—street traffic, people going about their business—has a casual, almost pastoral quality that differs from the modernist perspective of later city-symphony films like Paul Strand and Charles Sheeler’s Manhatta (1921). Take note of the surprising and remarkably timeless expression of boredom exhibited by a young girl filmed as she was chauffeured down Fifth Avenue in the front seat of a convertible limousine."

L'odorato come chiave per la memoria. Discorso scientifico e non banalmente appoggiato sulla madaleine di Proust.
Money quote: "he first attempt to empirically disentangle the Proustian effect was published in 1984. Researchers at Duke University in North Carolina performed two experiments in which autobiographical memories evoked by odours were compared with those evoked by photographs or words. The research showed that odour memories were less frequently reminisced upon, prior to the experiment, than those cued by the other sensory modalities. So, it seemed that (as could be inferred from Proust’s narrator) odour-induced memories were relatively novel and remote: that’s perhaps why actively seeking out such experiences does little to recreate the effect"

Fake news o l'antica legge del contrappasso? A patire di più gli effetti del riscaldamento globale sarà l'America che ha votato il negazionista Donald Trump

La Stampa questa mattina ha un bel montaggio sull'acqua. Gli sperperi dell'acqua pubblico-privata (il referendum ve lo ricordate? Ne fu campione Stefano Rodotà, da poco scomparso, ma il portato del voto è stato praticamente azzerato in sede esecutiva) ma anche un più complessivo discorso per quanto riguarda la resilienza richiesta adesso per costruire risposte alla crisi montante dell'acqua, che nei prossimi decenni ci travolgerà se non costruiamo adesso una risposta. Molto interessante.
Moneyt quote: "E poi un grande investimento culturale e politico per prevenire i conflitti, che inevitabilmente sorgeranno quando l’acqua sarà meno abbondante e tutti la pretenderanno. Si chiama resilienza e bisogna costruirla prima dell’emergenza, dopo sarà tardi. "

Money quote: "Rewards were smaller a half century ago, but there was just as much entrepreneurship. What can I possibly have done in the seven years that I’ve been accumulating stuff to justify rewarding me and my successors with a perpetually growing stream of work-free income? In short, nothing. I do not exaggerate. I’ve studied the market as an economist and as a political theorist. I’ve lived it as a wage earner and as a business owner. It’s not just me and my wife. It’s how the economy works."

One person’s experience becoming a business owner shows how our economy is based on luck rather than merit and how it rewards people who own stuff rather than people who do stuff.
La respirazione volontaria nei delfini e nelle balene, opposta alla nostra che è involontaria, provoca delle conseguenze singolari.
Come dormono senza annegare i delfini e le balene?
Money quote: "When marine mammals sleep and swim at once, they are in a state similar to napping. Young whales and dolphins actually rest, eat and sleep while their mother swims, towing them along in her slipstream--a placement called echelon swimming. At these times, the mother will also sleep on the move. In fact, she cannot stop swimming for the first several weeks of a newborn's life. If she does for any length of time, the calf will begin to sink; it is not born with enough body fat or blubber to float easily."

La folle vita, piena di folli idee, di Stepan Pachikov, inventore tra le molte altre cose di Evernote
Money quote: "Pachikov had been obsessed with the human brain, and particularly with developing software that would ensure that children go through the essential stages of brain development faster. This, he believes, would make them potentially smarter as they grew. From those questions about the brain came yet another idea: what if you could make a copy of your brain? What if he could develop a system to have your brain backed up? “The idea was that if you die, you could be resurrected, maybe in a few hundred years. It was easy to come to that idea because we can already replicate genes, but when we die, we lose our memory.”"

L'economia è diventata una religione. Ma i suoi preti, gli economisti, sono se possibile ancora peggio di quelli veri a fare previsioni.
Money quote: "Yet if history teaches anything, it’s that whenever economists feel certain that they have found the holy grail of endless peace and prosperity, the end of the present regime is nigh. On the eve of the 1929 Wall Street crash, the American economist Irving Fisher advised people to go out and buy shares; in the 1960s, Keynesian economists said there would never be another recession because they had perfected the tools of demand management."

Donald Trump piace molto ad alcuni ma non a tutti. Soprattutto, non piace all'establishment americano. Quali problemi sorgeranno?
Money quote:
"His nutty behavior is bad enough at home; it’s even worse abroad when he is supposed to be representing not just his rabid base of “deplorables” but, rather, the whole country. That is something Trump simply does not know how to do.
Thus, in the course of this trip, he trashed his predecessor, the U.S. intelligence community, and the “fake news” media. Can you imagine Ronald Reagan in 1981 going abroad and attacking Jimmy Carter for not doing more to stand up to Soviet aggression? Or attacking the press for being hostile to him in the 1980 campaign (as they were) and the intelligence community for not predicting the Iranian revolution (as they did not)? It’s unimaginable, yet Trump somehow thinks that it’s appropriate."

Un lungo, complesso articolo sull'inclusione nel posto di lavoro e sull'idea stessa del lavoro e su mille altre cose apparentemente piccole e casuali ma in realtà gigantesche, se ci pensate bene. Un articolo difficile da seguire perché il tono diaristico-personale offre pochi spunti di sintesi e astrazione della riflessione. Ma molto, molto interessante lo stesso.
Money quote: "See, here’s the thing: there are many ways to build an inclusive environment, and to enjoy the diversity that often follows from it. One great way, that I think might’ve been overlooked, is to keep things professional. When our office culture is focused on business rather than socializing, we reduce the number of ways in which we all have to be the same. When we do that, we allow diversity to flourish. If your culture expects people to work long hours or hang out off-hours, the strain on the people who are different, in whatever way, is increased, and your ability to retain a diverse work force is reduced."

Papa Francesco, le ostie senza glutine e un problema di dottrina che sembra banale ma tale, per il credente, non è.
Money quote: "Now, Francis and the Church that he presides over are taking steps to ensure that the holy ceremony of the Eucharist is not besmirched by any gluten-free products. In a recent letter to bishops written by Cardinal Robert Sarah, "at the request of Pope Francis," gluten-free bread is deemed "invalid matter" for the celebration of the Eucharist.
The Eucharist, or Holy Communion, is the ceremony instituted by Jesus Christ himself at the Last Supper, which consists of consuming bread and wine in order to commemorate Christ's sacrifice. Catholics believe that bread and wine are converted into the body and blood of Christ through a process called transubstantiation."
