The Wright Flyer first took off 110 years ago today. If it never stopped flying, how far could it have gone by now?
This sounds like a joke, but it’s not. A team of physicists were fooling around with photons when they managed to get the particles to clump together to form a molecule, one that’s unlike any other matter. And it behaves, they say, just like a light saber.
That’s right. Lasers were used to discover a new form of matter that’s straight out of a Star Wars film. Credit for the experiment goes to Harvard physics professor Mikhail Lukin and MIT physics professor Vladan Vuletic, who blasted photons through a cloud of rubidium atoms. When they sent more than one photon at once, they noticed that the particles clung to each other to form a molecule.

When kids eat glue, they’re exhibiting a lack of common sense. Computers equipped with artificial intelligence, it turns out, suffer from a similar problem.
While computers can tell you the chemical composition of glue, most can’t tell you if it is a gross choice for a snack. They lack the common sense that is ingrained in adult humans.
For the last decade, MIT researchers have been building a system called ConceptNet that can equip computers with common-sense associations. It can process that a person may desire a dessert such as cake, which has the quality of being sweet. The system is structured as a graph, with connections between related concepts and terms.
The University of Illinois-Chicago announced today that its researchers put ConceptNet to the test with an IQ assessment developed for young children. ConceptNet 4, the second-most recent iteration from MIT, earned a score equivalent to the average 4-year-old. It did well at vocabulary and recognizing similarities, but did poorly at answering “why” questions. Children would normally get similar scores in each of the categories.
