Helter Skelter: Negli aeroporti americani conosceranno il teorema di Bayes?
I dubbi di un viaggiatore potenziale terrorista Chi è stato in un aeroporto degli Stati Uniti dopo l'11 settembre sa che, al momento di imbarcarsi per ritornare a casa, i controlli antiterrorismo sono molto severi. In particolare, oltre a farti togliere scarpe, cinture, protesi dentali e cateteri, c'è il test anti esplosivo. Tipicamente ti passano un tampone sulle mani, sui vestiti e sulla valigia e poi lo cacciano in un macchinino da cui dipende il tuo destino. Il macchinino ingoia il tampone, ci pensa un attimo e poi fa muovere una lancetta su una scala graduata.
Study suggests humans are only capable of having five people in their closest circle
(Phys.org)—A trio of researchers affiliated with the University of Oxford in England and Aalto University School of Science in Finland has conducted a study of human behavior and has found evidence backing up a prior theory that suggests humans have different layers that make up their social circle with different numbers of people in them. In their paper uploaded to the preprint server, arXiv, they describe their study which involved analyzing cell phone records to count calls, what they found and that they believe it means for us a group. One of the researchers, Robin Dunbar, was part of a team that back in the 1990's studied the correlation between brain size in primates and the number of individuals in their social groups. They found that the bigger the brain, the more members of their groups.
What Is Nothing? A Mind-Bending Debate about the Universe Moderated by Neil deGrasse Tyson
by Maria Popova “You can’t assert an answer just because it’s not something else.” Isaac Asimov — sage of science, champion of creativity in education, visionary of the future, lover of libraries, Muppet friend — endures as one of the most visionary scientific minds in modern history. Every year, the Hayden Planetarium at the American Museum of Natural History, of which Asimov had been a tenacious supporter, hosts the Isaac Asimov Memorial Debate, inviting some of the greatest minds of our time to discuss monumental unanswered questions at the frontier of science. The 2013 installment explored the existence of nothing in a mind-bending conversation between science journalist Jim Holt, who has previously pondered why the world exists, theoretical physicist Lawrence Krauss, who has explored the science of “something” and “nothing,” Princeton astrophysics professor J. The crucial notion of the calculus is the notion of the infinitesimal — the infinitely small.

Frank Wilczek on Beauty, Physics, and Philosophy
We recognize beauty when we see it, right? Michelangelo’s David, Machu Picchu, an ocean sunrise. Could we say the same about the cosmos itself? Frank Wilczek, a professor of physics at the Massachusetts Institute of Technology, thinks we can. And should.
Algorithmicity, Islamic Art, and Virtual Philosophy: Thoughts on Laura Marks’ ‘Enfoldment and Infinity’
One of the most incredible works of architecture I’ve ever seen: The Hall of the Two Sisters in the Alhambra, Granada. The dome is composed of a multitude of tiny, pixel-like cells known as muquarna. “The universe is not dualistic, but folded, so spirit is separated from matter only by degree” – Laura Marks, Enfoldment and Infinity: An Islamic Genealogy of New Media Art (2010, p. 271). As someone deeply invested in using networks to understand a wide range of phenomenon, I was thrilled to see Laura Marks’ new book Enfoldment and Infinity: An Islamic Genealogy of New Media Art. But I had little sense of just how amazing this book was going to be.
Fractal patterns in nature and art are aesthetically pleasing and stress-reducing
Humans are visual creatures. Objects we call “beautiful” or “aesthetic” are a crucial part of our humanity. Even the oldest known examples of rock and cave art served aesthetic rather than utilitarian roles. Although aesthetics is often regarded as an ill-defined vague quality, research groups like mine are using sophisticated techniques to quantify it – and its impact on the observer.

Il dizionario della complessità
Provate a immaginare di prendere a prestito il signor Palomar dal libro omonimo di Italo Calvino e di fargli osservare, una notte d’estate, il cielo. Esso lo colpirà immediatamente per la confusione di stelle, disperse a caso. Provate ora a indurre il signor Palomar a esaminarlo una seconda volta. Quel disordine gli apparirà come un ordine cosmico, imperturbabile notte dopo notte.

Whenever you say anything about your daily life, a scale is implied. Try it out. “I’m too busy” only works for an assumed time scale: today, for example, or this week. Not this century or this nanosecond. “Taxes are onerous” only makes sense for a certain income range.
