Chapter Five: The Temperature of the Beak Needle

When the blue light crossed the threshold, the ice did not harden. It boiled. Crystals left their lattice and hung like vapor in an invisible flame. Four probes gave four answers: minus 203 Celsius, forty-seven Celsius, absolute zero, and no data. "It isn't changing heat," Su said. "It is changing how we define heat." Images covered the door: flame, crystal, particles dispersing into disorder, and a curve flowing from high to low. "Temperature isn't a substance," Lin said. "It is a statistical description of motion. Heat flowing from hot to cold is the common face of increasing entropy." Chen remained behind them. "The beak needle turns a person with the wrong understanding into uniform heat."
