“With no training and far more limited technical tools than those of a state intelligence service, we were able to use the location data — date, time and length of stay — to make basic inferences. By determining whether two people were in the same place at the same time, it was easy to zero in on spouses, co-workers or friends. Cataloguing their movements revealed even more associations, creating the map of a robust social network that would be nearly impossible to determine through traditional surveillance. In cases where it was difficult to identify an individual, associations offered more clues about workplaces and interests.”

“When I left Hell Creek, DePalma pressed me on the need for secrecy: I was to tell no one, not even close friends, about what he’d found. The history of paleontology is full of tales of bribery, backstabbing, and double-dealing. In the nineteenth century, Othniel C. Marsh and Edward Drinker Cope, the nation’s two leading paleontologists, engaged in a bitter competition to collect dinosaur fossils in the American West. They raided each other’s quarries, bribed each other’s crews, and vilified each other in print and at scientific meetings. In 1890, the New York Herald began a series of sensational articles about the controversy with the headline “Scientists Wage Bitter Warfare.” The rivalry has since become known as the Bone Wars. The days of skulduggery in paleontology have not passed; DePalma was deeply concerned that the site would be expropriated by a major museum.” “}}

“Jump to 2017, when Google unveiled AlphaZero, a computer that had been given the rules of chess and then taught itself how to play. It took four hours of training to be able to beat Stockfish, the best chess machine programmed with human tactics. Intriguingly, AlphaZero made what looked like blunders to human eyes. For example, in the middlegame it sacrificed a bishop for a strategic advantage that became clear only much later.
Quant funds can be divided into two groups: those like Stockfish, which use machines to mimic human strategies; and those like AlphaZero, which create strategies themselves. For 30 years
quantitative investing started with a hypothesis, says a quant investor. Investors would test it against historical data and make a judgment as to whether it would continue to be useful. Now the order has been reversed. “We start with the data and look for a hypothesis,” he says.”
