We give a geometric, more constructive proof of Peck's Theorem on the
simultaneous Diophantine approximation of algebraic numbers. Unlike
the original argument of L.G. Peck (1961), which relies on analytic
distributions of units in log-space and trace-form computations, our
approach focuses on the interaction between the Minkowski embedding of
a field \(K\) and the discrete dynamics of the unit group
\(\mathcal{O}_{K}^{\times}\). By introducing a specific linear
transformation \(A\) into the dual lattice space, we show that the
approximation problem can be interpreted as a sequence of contractions
and rotations within the complex embeddings of \(K\). We then show
that the multiplicative action of the fundamental units produces a
spiral-like trajectory that, together with Dirichlet's Approximation
Theorem, drives dual lattice points into a chosen neighborhood of the
approximation axes. This viewpoint gives a more direct geometric sense
of the \(\log(q)\) factor and clarifies how the arithmetic structure
of algebraic units influences the quality of simultaneous
approximations.
