**Abstract: **A complex number z is said to be algebraic, if there is a univariate f(x) with real coefficients such that f(z)=0. For instance i, the square root of -1, is algebraic with f(x) being x^2 + 1.

**Abstract:** In 1971, Graham and Pollak showed that if $D_T$ is the distance matrix of a tree $T$ on $n$ nodes, then $\det(D_T)$ depends only on $n$, not $T$.
