We consider a toy model of pointer interacting with a 1=2-spin system, whose r x variable is measured by the environment, according to the prescription of decoherence theory. If the environment measuring the variable r x yields ordinary statistical mechanics, the pointer sensitive to the 1=2-spin sy

The Ghosh-Berkowitz-Parr macroscopic thermodynamic description of an electronic ground state is reviewed. The information entropy defined in this theory is calculated for several atoms using Hartree-Fock and double-zeta wave functions. It is shown that the information entropy is a measure of wave fu
