  The Lorenz attractor was introduced in 1963 by E. N. Lorenz as one of the
first examples of \emph{strange attractors}. However Lorenz' research was
mainly based on (non-rigourous) numerical simulations and, until recently, the
proof of the existence of the Lorenz attractor remained elusive. To address
that problem some authors introduced geometric Lorenz models and proved that
geometric Lorenz models have a strange attractor. In 2002 it was shown that the
original Lorenz model behaves like a geometric Lorenz model and thus has a
strange attractor. In this paper we show that geometric Lorenz attractors are
computable, as well as their physical measures.
