There is a blind spot in AI research
Nature 538, 7625 (2016). doi:10.1038/538311a
Authors: Kate Crawford & Ryan Calo
Fears about the future impacts of artificial intelligence are distracting researchers from the real risks of deployed systems, argue Kate Crawford and Ryan Calo.

A shortest-possible walking tour through the pubs of the United Kingdom — that’s an advanced form of the mathematicians’ favorite, The Traveling Salesman Problem. William Cook and colleagues at the University of Waterloo tackled this nastily complex problem:
Nearly everyone in the UK knows by heart the best path to take them over to their favorite public house. But what about jotting down the shortest route to visit every pub in the country and return home safely? That is what we set out to do….
Using geographic coordinates of 24,727 pubs provided by Pubs Galore and measuring the distance between any two pubs as the length of the route produced by Google Maps, what is the shortest possible tour that visits all 24,727 and returns to the starting point? …
This is the problem we have solved. The optimal tour has length 45,495,239 meters. To be clear, our main result is that there simply does not exist any pub tour that is even one meter shorter (measuring the length using the distances we obtained from Google) than the one produced by our computation. It is the solution to a 24,727-city traveling salesman problem (TSP).
The UK Pubs tour is easily the largest such road-distance TSP that has been solved to date, having over 100 times more stops than any road-distance example solved previously by other research groups.
Here’s one low-resolution sliver of what is a much more detailed map of the tour:

Since Death Valley is below sea level could we dig a hole to the ocean and fill it up with water?
—Nick Traeden
Yes! We can do anything we want. We shouldn't do this, though, because it would be gross.
Death Valley is an endorheic basin[1]"Big hole" in California. The floor of the valley is about 80 meters below sea level. It contains the lowest point on land in North America[2]Excluding artificial points like mines. and is the hottest place on Earth.[3]If you're about to say "Wait, what about Liby—," then don't worry, I'm with you. Just hang on and read a few more words ahead!
Now, if you're the sort of person who's into world records, you might have heard that the hottest place on Earth was Al Azizia, Libya. Al Azizia recorded a temperature of 58.0°C (136.4°F) in 1922, a mark Death Valley has never come close to. So what gives?
It turns out Al Azizia has recently been stripped of its record. In 2010, an exhaustive—and definitely a little obsessive—investigation led by Christopher C. Burt convinced the World Meteorological Organization that the Libyan measurement was probably a mistake. This left Death Valley with the record of 56.7°C (134°F), set in 1913. Case closed!
Except it's not quite settled. Burt has raised questions about the 1913 record as well, and has gone so far as to catalog a number of historical extremes along with a credibility score for each. The "real" record is probably 53.9°C (129°F). This temperature has been recorded four times, in 1960, 1998, 2005, and 2007—every time in Death Valley.
These records were recorded with modern instruments and are considered reliable. They also make sense from a theoretical point of view. Geographers have calculated[4]This Army Corps of Engineers publication cites a couple of sources for this, including a 1963 paper by G. Hoffman. Unfortunately, that paper is in German, which I can't read, so I've just decided to trust that the Army Corps of Engineers writers Dr. Paul F. Krause and Kathleen L. Flood aren't pulling a fast one on me. that the highest possible temperature in ideal spots (in desert basins like Death Valley) during the 20th century is 55°-56°C, so 54°C sounds like a reasonable world record.
Now, back to Nick's question.[5]This is nowhere NEAR the record for "most boring digression into world record trivia." That record was recently challenged by IBM computer capable of producing millions of boring pieces of trivia per second, but the machine narrowly lost to reigning human champion Ken Jennings.
Since Death Valley is below sea level, we could, as Nick suggests, flood it with seawater. It would take a lot of digging, since there's a lot of Earth in the way. The lowest route to Death Valley is probably by traveling up the Colorado River watershed, along the Arizona border past Quartzsite,[6]Trivia: If you want to reach Quartzsite, Arizona from my school, Christopher Newport University, you just step out onto Warwick Blvd (Rt. 60) and turn left. That's it—Route 60 runs across the country, from the CNU campus in Virginia to I-10 just outside Quartzsite. then northwest[7]Possibly following one of the routes shown on page G34 in this report. past Zzyzx, which is a real place.
If you did all that digging, you could create a channel from the Gulf of California to Death Valley, and water would flow in. We can use this handy stream-flow calculator to figure out how wide we'd need to make the channel. A channel 20 meters deep and 100 meters wide should be able to fill it in a few months. A really wide channel—like the kind carved by glacial floods—could fill it in hours.
We know it's possible to create this kind of inland sea because we've done it before—by accident. In 1905, irrigation engineers working on the Colorado River made some mistakes. During a flood, the entire Colorado river broke through into the Alamo Canal and flowed directly into the Salton basin to the north. By the time they repaired the canal, two years later, the Salton basin had become the Salton Sea—one of the larger human-caused changes to the world map.
The Salton Sea is fed mainly by agricultural runoff, so it's become saline[8]"Salty" and hypereutrophic.[9]"Gross" Large numbers of dead fish, combined with algal decay and unusual chemistry, have created a smell that the US Geological Survey describes as "objectionable," "noxious," "unique," and "pervasive." The sea is a birdwatching hot spot, but also the site of a lot of mass bird die-offs, so kind of a mixed bag if you're into birds. In recent years, the water has been evaporating quickly, leaving behind dried toxic residue which is swept up into dust storms. Work to clean up and rehabilitate the region is ongoing.
All in all, the Salton Sea is a mess—and Nick wants to make another one.
Nick's Death Valley project would start off connected to the ocean, but without a source of flowing water at the Death Valley end,[10](It's a desert.) the channel would gradually silt up. The link to the ocean would eventually be broken, the sea would start to evaporate, the water would become saline, algae would bloom, and eventually the US Geological Survey would start complaining about the smell.
There would be one more consequence to all this. Thanks to the flood of cold ocean water burying the whole region, Death Valley would stop setting temperature records, and someone else would eventually claim to have broken their 129°F record. The Death Valley records would have to be compared to the newer candidates, which would probably use slightly different methods ... and that means one thing:
A World Meteorological Organization expert panel!

Interplay between evanescence and disorder in deep subwavelength photonic structures
Nature Communications, Published online: 6 October 2016; doi:10.1038/ncomms12927
Features much smaller than the wavelength are not expected to have a significant impact on the transport of a wave. Here, the authors show that Anderson localization can dominate light transport in a one-dimensional disordered system, even when the disordered features are a thousand times smaller than the wavelength.

Nel 1986 il summit di Reykjavik fra il presidente degli Stati Uniti Ronald Reagan e il premier sovietico Mikhail Gorbaciov decise i destini del mondo. In quell'incontro giocò un ruolo fondamentale una donna, Joan Quigley. Fu lei a scegliere l'orario della partenza di Reagan per Reykjavik. Il capo di gabinetto della Casa Bianca di allora, Donald Regan, racconta che quasi ogni decisione e ogni spostamento importante, compresa la firma dei trattati sulle armi nucleari, dipendeva dall'approvazione dalla Quigley, che aveva potere di veto sugli orari di tutte le conferenze stampa presidenziali e indicava quando era sicuro viaggiare e quando organizzare un summit [video; video]. Joan Quigley era l'astrologa di Ronald Reagan.![]() |

Dopo la Seconda Guerra Mondiale potere e pseudoscienza hanno continuato ad andare a braccetto. La ricerca scientifica sovietica sulla telepatia, o “comunicazione biologica” come la chiamavano i russi, era iniziata già negli anni Venti del secolo scorso e fu svolta presso l’Università di Leningrado, pensando di applicarla alle comunicazioni segrete con le navi.
Il personaggio del generale Hopgood che nel film è convinto di poter attraversare i muri con la forza del pensiero è reale: è basato su Albert Newton Stubblebine III, generale dell’esercito statunitense, comandante dell’INSCOM (US Army Intelligence and Security Command) dal 1981 al 1984, uomo chiave nell’invasione militare americana di Grenada nel 1983.
Ultimo aggiornamento: 2016/10/04 8:30. Star Trek ha sempre offerto una visione positiva del futuro, una visione di speranza e di ottimismo e, cosa più importante, di inclusione, nella quale le persone di tutte le razze ricevono pari rispetto e dignità, nella quale le credenze e gli stili di vita individuali vengono rispettati purché non siano una minaccia per gli altri. Non possiamo restare indifferenti di fronte a quello che sta accadendo nell’elezione che sta arrivando. Non c’è mai stato un candidato alla presidenza così completamente all’opposto degli ideali dell’universo di Star Trek come lo è Donald Trump. Eleggerlo farebbe arretrare questo paese, forse in modo disastroso. Dobbiamo eleggere un presidente che spingerà questo paese in avanti, verso il tipo di futuro che tutti sogniamo, nel quale le differenze personali vengono capite e accettate, nel quale la scienza scavalca la superstizione, e nel quale le persone lavorano insieme invece che l’una contro l’altra.
La risoluzione dei conflitti in Star Trek non è mai stata facile. Non restate indifferenti: votate! Abbiamo sentito gente dire che voterà per i Verdi o i Libertarian o non voterà affatto perché entrambi i candidati principali sono ugualmente colmi di difetti. Questo è illogico e anche inesatto. La Casa Bianca verrà occupata o dal Segretario Clinton o dal signor Trump. Uno è un dilettante che ignora con condiscendenza le leggi nazionali e le realtà internazionali; l’altra ha dedicato la propria vita al servizio pubblico e ha un’esperienza profonda e preziosa oltre ad aver dimostrato di essere capace di lavorare con il Congresso per far approvare leggi di cui c’era disperato bisogno. Se, come dicono alcuni, il governo si è rotto, un voto di protesta non lo aggiusterà.
Avete appena compiuto 18 anni? Avete traslocato? Non avete mai votato prima? Alcuni stati offrono una registrazione anticipata (ai primi di ottobre) e/o il voto per corrispondenza. Non potete votare se non vi siete registrati. Per cui attivatevi: andate a https://www.rockthevote.com, un’associazione neutrale senza scopo di lucro, e fare il vostro dovere civico. Perché, dannazione, siete cittadini americani, e avete l’obbligo di far parte della nostra democrazia! Fatelo non solo per voi stessi, ma per tutte le generazioni che seguiranno. Votate per un futuro di persone illuminate e d’inclusione, per un futuro che un giorno ci porterà alle stelle.
