Physicists Spot Quantum Tornadoes Twirling in a ‘Supersolid’
In a lab nestled between the jagged peaks of the Austrian Alps, rare earth metals vaporize and spew out of an oven at the speed of a fighter jet.

The roughly 50,000… Continue reading Physicists Spot Quantum Tornadoes Twirling in a ‘Supersolid’
How Is AI Changing the Science of Prediction?
Scientists routinely build quantitative models — of, say, the weather or an epidemic — and then use them to make predictions, which they can then test against the real thing. This work can reveal how well we understand complex phenomena, and also dictate where research should go next. In recent years, the remarkable successes of… Continue reading How Is AI Changing the Science of Prediction?

Debate May Help AI Models Converge on Truth
In February 2023, Google’s artificial intelligence chatbot Bard claimed that the James Webb Space Telescope had captured the first image of a planet outside our solar system. It hadn’t. When researchers from Purdue University asked OpenAI’s ChatGPT more than 500 programming questions, more than half of the responses were inaccurate. These mistakes were easy to… Continue reading Debate May Help AI Models Converge on Truth
