A <Python> wrapper over a bunch of <numerical software>[numeric] and <computer algebra system> packages to try and fully replace <MATLAB> et. al.

$$
QQ^3
$$
is the <3D> <vector space> over the <rationals>. This also suggests that they are quite focused on <computer algebra system>[computer algebra] as opposed to numerical.
