Abstract

We treat the perihelion shift of the planetary motion and the Lamb shift in hydrogen in an arbitrary number of space dimensions. Comparison with experimental data shows that the deviation from dimensionality four of space-time is less than 109 and 3.6 × 1011, respectively, on the length scales associated with these phenomena.
