New, strange phases of matter
may include things like a molecular supersolid, a type of matter in which the molecules would be arranged in a solid shape but could flow inside the solid without friction.
Kids can learn about crystallization, specific heat, the phases of matter
, conversions, volumes and weights, and other science fundamentals.
The author cites the organization implicit in the phases of matter
and the paradoxical role of collective behavior in quantum measurement.
The laws of thermodynamics predict that gases and other phases of matter
progress toward a state of maximum entropy.
Confusingly the term "gauge" is still used although it refers no longer to changes in the phases of matter
waves and of the internal properties of subatomic particles (the properties that determine their identities, really) that are related to the phases.
