From Interactive System for Ice sheet Simulation

- Continuous function One that is everywhere differentiable. Also in Wikipedia.

- Liklihood: measure of the relative frequency with which an hypothesis can explain observations

- Monte Carlo sampling: repeated random sampling

- Roughness: deviation of a real surface and its ideal shape.

- Deviatoric stress: difference between the full stress and the spherical stress in a volume.

- Stencil: node arrangement used to pass information through a numerical solution to a differential equation.

- Strain: measure of relative displacement between particles in a continuous material body; deformation of the material. Note the distinction between finite and infinitesimal strain theory.

- Strain rate: change in strain over time.

- Taylor Series: representation of a continuous function as the sum of an infinite series of terms. The terms are derivatives of the function at a point.

- Uncertainty: indistinguishable interpretations of observational data
