About how long would it take for a (full) can of beer at room temperature to topple over spontaneously, as a result of quantum tunneling? *Hint:* Treat it as a uniform cylinder of mass m, radius R, and height h. As the can tips, let x be the height of the center above its equilibrium position (h/2). The potential energy is mgx, and it topples when x reaches the critical value x0=R2+(h/2)2−h/2. Calculate the tunneling probability (Equation 9.23), for E=0. Use Equation 9.29, with the thermal energy ((1/2)mv2=(1/2)kBT) to estimate the velocity. Put in reasonable numbers, and give your final answer in years.
