Curds show the whey: The vexing problem of the glass transition has been frustrating experimentalists and theorists for more than a century. One difficulty is in quantifying the structure of an inhomogeneous system, even when “curds” and “whey” are made out of the same material. To explore the rich space of configurations of these complex systems, a new generation of experiments with a range of different local probes is needed.
