Ah, physics humor. Anyway, it’s been too long since I made a pure science post. I’ve been trying to wean myself off, but when I saw Jon Cartwright’s article on physicsworld.com, I couldn’t help myself. According to the article, an international team of physicists has proposed a new device that could detect the presence of waves or particles while barely disturbing them. Called a “Schrödinger’s hat”, the device has not yet been built in the lab but the team believes that it could someday be used as a new type of sensor for quantum-information systems.
