We discuss a pair of isoperimetric problems which at a glance seem to be unrelated. The first one is classical: one places N identical point charges at a closed curve T at the same arc-length distances and asks about the energy minimum, ie which shape does the loop take if left by itself. The second problem comes from quantum mechanics: we take a Schrdinger operator in
