Il sonnambulismo è stato finalmente spiegato. Serviva alla sopravvivenza in tempi preistorici ma, con l’emergere dell’uomo moderno che parla e che ragiona, è nato un problema è adesso funziona molto, molto male.
Money quote: “Sometimes, of course, sleepwalking is dangerous. Somnambulists are in an irrational state during which they could harm themselves or others. Some extreme examples include the instance of the English teenager who in 2009 jumped eight metres out of her bedroom window, or the case of Kenneth Parks in Toronto, who in 1987 drove 23km and murdered his mother-in-law, all apparently while sleeping. Parks committed the act – if that’s the right word – despite an agreeable relationship with the victim and a lack of motive”

Nuove frontiere del pensiero: contro i privilegi legali del matrimonio. (Pensa te...)
Money quote: “It seems, then, that single people have finally arrived, poised to take their rightful place alongside married couples when it comes to status, power and respect. Except for one thing: single people still don’t have access to the legal benefits and protections the government grants to those who get married. In the US, there are more than 1,100 laws benefiting married couples, and that’s just at the federal level; many states offer perks and protections as well”

Interessante riflessione sulla sharing economy e sull’equità del mondo che stiamo costruendo.
Money quote: “What I neglected to account for is that the foundation of the Sharing Economy is backed by the wealthy, who seek to become even wealthier, thus creating a greater economic divide. One can argue that startups generate new wealth as well as returns for investors, but that’s only a sliver of the pie. Like many technocrats, Paul Graham is vocal in his belief that economic inequality is central to the motivation of entrepreneurs and growth of new companies. This is fundamentally false — innovation would be even sexier to entrepreneurs if the majority were thriving. After all, a healthy middle class is good for business.”

Sixty-nine percent of the surveyed young farmers had college degrees — significantly higher than the general population.
This new generation can’t hope to replace the numbers that farming is losing to age. But it is already contributing to the growth of the local-food movement and could help preserve the place of midsize farms in the rural landscape."

I sogni che l’impero britannico aveva collezionato per cercare di meglio capire il suo enorme impero -e che poi non ha ascoltato.

In an attempt to better understand their colonial subjects in those years, officials in the British empire undertook a curious and little-known research project: to collect dreams from the people of South Asia, Africa and the Pacific. The results were not what they expected. “

Amazon, lo sciopero e i sindacati. Una riflessione non banale di Lorenzo Cavalieri che vi consiglio di leggere sino in fondo. Perché secondo me più che il ruolo propositivo delle multinazionali - per altri versi criticabili ma per questo no - il commento ci offre uno spunto su quale dovrebbe essere il uomo di un sindacato che voglia sopravvivere a se stesso.
Money quote: “Questo discorso da adulto ad adulto non ce lo dovrebbe fare un’azienda americana che fattura miliardi. Ce lo dovrebbero fare la scuola, la politica e il sindacato. Tutti presenti quando c’è da protestare. Tutti assenti quando i megafoni e i post sui social spariscono e restiamo da soli a guardarci allo specchio e a dirci “e io adesso che faccio”.”

Anne, la figlia del generale De Gaulle.
Money quote: “Anne de Gaulle era nata il 1° gennaio 1928, ultima di tre figli. A pochi mesi dalla nascita fu chiaro che era disabile. In quel periodo i bambini disabili erano tenuti nascosti se non allontanati e inseriti in istituti scarsamente attrezzati a prendersi cura di loro. La trisomia 21 non era ancora stata identificata come tale – avverrà solo 30 anni dopo la nascita di Anne – e si ipotizzava che la causa fosse l’alcolismo di uno dei genitori. Vista la caratteristica facies venivano chiamati mongoloidi, appellativo che anche allora aveva un significato sgradevole”

Vi prego, vi scongiuro (e scongiuro soprattutto quelli di voi che per lavoro hanno a che fare direttamente o indirettamente con i bambini): ascoltate il podcast di Repubblica "Veleno". Sono 7 puntate e sono già tutte disponibili. Continuate ad ascoltarlo anche dopo la prima puntata, che è ostica e sembra voler portare da tutt'altra parte. Dico davvero: serve saper riconoscere un tipo di errore che viene spesso fatto (e non solo da noi: è ricorrente in varie parti del mondo) per non far sì che sì ripeta malgrado le premesse siano note.
E se per caso ci fosse anche qualche rappresentante delle istituzioni che che si impegnasse per rimuovere dai rispettivi incarichi e dagli albi professionali i colpevoli di quel particolare caso (nel dettaglio, una psicologa infantile emiliana e una ginecologa milanese che la clinica Mangiagalli ha già allontanato, ma continua a praticare presso il suo studio privato e si dice specializzata in un tipo di ginecologia che fa uso di fitoterapia, aromaterapia e Fiori di Bach), ecco, anche quello non sarebbe male.

Un vantaggio competitivo è vederci chiaro, in maniera sintetica e con gli indicatori giusti. Una parte della strategia di Elon Musk legata alla sua Tesla e alle altre cose che rigurdano l'elettricità è che ha capito qual è la tendenza del mercato per le batterie al litio. Cioè, i prezzi si abbassano. E lui scommette su questo.
Money quote: "With battery prices tumbling by almost half since 2014, large-scale projects are popping up around the world.

Il problema degli aeroplani con motore elettrico è che le batterie, che siano piene o che siano vuote, pesano sempre lo stesso. Questo pone importanti diseconomie. Però ci si lavora lo stesso, soprattutto per i voli a corto raggio, quelli da "pendolari" o "regionali". Il consorzio Airbus-Siemens-RollsRoyce è la punta di diamante nello studio per queste opzioni. Qui il comunicato originale di Airbus (che troverete straordinariamente simile a molto lavoro della stampa nostrana).

Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven."
