Figure 1
A comparison of the molecular-biophysics length scales and timescales accessible to simulation and experiment. The term `spherical cows' refers to approximate models that provide an abstract representation of a physical system; such models are useful because of the simplicity of the calculations (e.g. volumes or surface areas of a herd can be easily estimated by assuming that cows are spherical and assigning a radius) and the general nature of the model (the volume of a goat herd can easily be compared).
