Can an aging corporation’s adventures in fundamental physics research open a new era of unimaginably powerful computers? In 2012, physicists in the Netherlands announced a discovery in particle physics that started chatter about a Nobel Prize. Inside a tiny rod of semiconductor crystal chilled cooler than outer space, they had caught the first glimpse of a strange particle called the Majorana ferm
The Revolutionary Technique That Quietly Changed Machine Vision Forever Machines are now almost as good as humans at object recognition, and the turning point occurred in 2012, say computer scientists. In space exploration, there is the Google Lunar X Prize for placing a rover on the lunar surface. In medicine, there is the Qualcomm Tricorder X Prize for developing a Star Trek-like device for diag
Carbon, Avogadro’s Constant and the Importance of the Number 12 Materials scientists have decided to define, rather than measure, Avogadro’s constant, triggering a lengthy debate over what number to choose. Now one physicist thinks he has the answer. The International System of Units (with the abbreviation of SI units) is one of the foundations of modern science. It consists of seven base units fr
Automation is reducing the need for people in many jobs. Are we facing a future of stagnant income and worsening inequality? Given his calm and reasoned academic demeanor, it is easy to miss just how provocative Erik Brynjolfsson’s contention really is. Brynjolfsson, a professor at the MIT Sloan School of Management, and his collaborator and coauthor Andrew McAfee have been arguing for the last y
Google’s PageRank algorithm was developed in 1998. But a project to trace the history of such algorithms reveals an example from the 1940s. The PageRank algorithm is a key part of Google’s method of ranking web pages in search results. It uses the network of links between web pages to determine their value and, famously, judges a page to be important if it is linked to by other important pages. On
A new generation of biologists embraces the do-it-yourself ethic of computer programming. In a spare bedroom of his family’s house in County Cork, Ireland, Cathal Garvey is repeating the feats that led to the dawn of the biotechnology age. He’s growing bacteria. He’s adding DNA. He’s seeing what happens. “To transform bacteria was once a huge deal, a new method,” he explains. “Today, you can do it
The discovery of a winning strategy for Prisoner’s Dilemma is forcing game theorists to rethink their discipline. Their conclusion? Winning isn’t everything. The world of game theory is currently on fire. In May, Freeman Dyson at Princeton University and William Press at the University of Texas announced that they had discovered a previously unknown strategy for the game of prisoner’s dilemma whic
