Abstract
The problem of describing macroscopic variables in quantum theory, is discussed. It is suggested that the ‘eigenspaces’ of macroscopic variables be hyperspheres rather than closed linear subspaces. This is combined with the usual suggestion that macroscopic variables are nearly diagonal in the energy representation. The Schrödinger paradox is resolved in terms of this discussion.
