An electric potential is set up across a pair of parallel plates
such that the left plate is at -509 V and the right plate is at 0V.
An electron is released at the left plate and accelerates towards
the right plate. When it reaches the right plate, it passes through
a small hole and enters a region where there...

Two identical nano-particles each contain 10 atoms. One nano-particle is on top of the other, and they are in contact, so energy can flow between them. The combined energy of both nano-particles is ten quanta. What is the probability that at a given instant, all the energy is in the top nano-particle?
