A brief technical supplement in support of our proposed new unit, the grrm. The grrm is a unit of change over time. Specifically, it measures the degree of warping of a shelf under a constant weight per distance over a given length of time. In terms of quality, more grrms represent a shelf that bends more under stress. In standardized units, 1 grrm can be described as: 1 degree of deflection under the weight of a full shelf of ASOIAF […]
