Redish et al. present a compelling, interdisciplinary, unified framework of addiction. The effort to integrate pathological gambling is especially important, but only the vulnerability of misclassifying situations is described in detail as being linked directly to this disorder. This commentary focuses on further developing the comprehensiveness of this framework for pathological gambling using over-fast discounting as an illustrative example.

This century is widely recognized as the Age of Analysis. "A posteriori" evidence is accumulating to demonstrate that the next century will be the Age of Synthesis. Synthesis will supplement analysis as a major thrust in our technological society. Synthesis requires a vision to project into the future, and demands a more holistic approach. Synthesis can help reduce the -two cultures- syndrome. Both natural and unnatural or human-made systems, involving the arts, sciences, the professions, and the applied fields, are discussed, (...) as well as the philosophy of Plato, Aristotle, Kant, and many other recognized philosophers.".

The purpose of the simultaneous measurement of noncommuting quantum observables can be viewed as the joint estimation of parameters of the density operator of the quantum system. Joint estimation involves the application of a multiply parameterized operator-valued measure. An example related to the simultaneous estimation of the position and velocity of a particle is given. Conceptual difficulties attending simultaneous measurement of noncommuting observables are avoided by this formation.
