Probability of pools freezing in summer

    One of my classmates asked an interesting question that I have no idea how to deal with. Prove that if ##\hbar=1##, then of every 1000 pools, one will freeze in summer!
    I really can think of nothing at all. Any suggestions?

    Well, since [itex]\hbar\approx 4.5\times10^{-16}\text{eV}\cdot\text{s}[/itex], then obviously you would see quantum uncertainty even for macroscopic objects if [itex]\hbar[/itex] was [itex]10^{16}[/itex] times larger.
