Stern-Gerlach Experiment2

Dear Members,

In Late Sakurai's " Modern Quantum Mechanics", in the description of
Stern-Gerlach experiment, you read "Because the atom as a whole is very
HEAVY, we expect that the CLASSICAL CONCEPT of trajectory can be
legitimately applied, ... " (p.3) what is the relevance of "heaviness
of atom" to classical concept of trajectory?
regards,

Ali
