Estimate the tunneling probability for an 
professor
approaching an 
thick wall at a top speed of 
. You may
take the height of the potential barrier 
to be given by the
energy of interspersing my molecules amongst those of the wall, resulting in
an energy on the order of 
per molecule. I am consist primarily
of water with a molecular weight of 
.
Explain why, in this case, you should ignore the step correction terms and consider only the WKB decay.
