    "abstract": "Quantum mechanical analysis of a rigid rod with one end fixed to a flat table\nis presented. It is shown, that for a macroscopic rod the ground state is\norientationally delocalized only if the table is absolutely horizontal. In this\nlatter case the rod, assumed to be initally in the upright orientation, falls\ndown symmetrically and simultaneously in both directions, as claimed by Tegmark\nand Wheeler. In addition, the time of fall is calculated using WKB\nwavefunctions representing energy eigenstates near the barrier summit.",
