Anything-goes “anyons” may be at the root of surprising quantum experiments

In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually exclusive; the presence of one should inherently destroy the other. Now, theoretical physicists at MIT have an explanation for how this Jekyll-and-Hyde duality […]

When it comes to language, context matters

In everyday conversation, it’s critical to understand not just the words that are spoken, but the context in which they are said. If it’s pouring rain and someone remarks on the “lovely weather,” you won’t understand their meaning unless you realize that they’re being sarcastic. Making inferences about what someone really means when it doesn’t […]
