# Classical limit of quantum mechanics

• The semi-classical limit corresponds to $h\rightarrow 0$, which can be seen to be equivalent to $m\rightarrow\infty$ , the mass increasing so that it behaves classically. (from http://en.wikipedia.org/wiki/Dynamical_billiards )

• An increasing mass can be seen as an increase in the number $N$ of involved particles with mass $m_0$. So is the limit of a $N$-particle quantum system for $N\rightarrow\infty$ a classical system??
