  "summary": "Chinese physicists have discovered that a tipping point – a threshold where a physical system rapidly shifts states – can possess a smooth mathematical structure resembling a doughnut’s hole, challenging a belief that the two phenomena must be studied separately. For decades, mainstream physicists have mostly treated critical phenomena, which describe how physical systems change at critical…",
