Onsager PrizeGlasses: a world with with a docile clock

Glasses let themselves be driven to evolve at wildly different speeds, both experimentally (for example by

shearing them, or by changing slightly pressure or temperature) or numerically (by using a clever unphysical algorithm).

This `time-reparametrization' is just like a film that remains always the same, but is projected at speeds that are

easily (and nonlinearly) changed. Together with this, they have the property that they choose their temperature at different timescales.

This general picture has the beauty that it makes no particular allusion to the microscopic details, which as we know may be very diferent from one glass to another.
