Beyond Weird: what does quantum mechanics really mean?
Quantum physics has a reputation as one of the most obscure and impenetrable subjects in science. But when the physicist Richard Feynman said in 1965 that he didn’t understand quantum mechanics, he didn’t mean that he couldn’t do it – he meant that’s all he could do. He didn’t understand what the equations were telling us about reality.
The enigma of quantum mechanics hasn’t lessened, but over the past decade or so it has come into sharper focus. We now realise that quantum mechanics is less a theory about particles and waves, uncertainty and fuzziness, than a theory about information: about what can be known and how. It calls into question the meanings and limits of space and time, cause and effect, and knowledge itself.
Philip Ball will talk about what quantum theory really means – and what it doesn’t – and how its counterintuitive principles create the world we experience.
