This is a brief reply to S. Goldstein's article “Quantum theory without observers” in Physics Today. It is pointed out that Bohm's pilot wave theory is successful only because it keeps Schrödinger's (exact) wave mechanics unchanged, while the rest of it is observationally meaningless and solely based on classical prejudice. 

Empty Waves in Bohmian Quantum Mechanics

There is a recurring line of argument in the literature to the effect that Bohm's theory fails to solve the measurement problem. I show that this argument fails in all its variants. Hence Bohm's

Why isn't every physicist a Bohmian?

This note collects, classifies and evaluates common criticism against the de Broglie Bohm theory, including Ockham's razor, asymmetry in the de Broglie Bohm theory, the ``surreal trajectory''

Pure Quantum Interpretations Are not Viable

Pure interpretations of quantum theory, which throw away the classical part of the Copenhagen interpretation without adding new structure to its quantum part, are not viable. This is a consequence of

On Historical Background to the Ontic Breakthrough.I Polemic Defense of Quantum Reality

After stating the author's ontic position, a collage of relevant thoughts of some distinguished foundationally-minded physicists are quoted and polemically commented upon. Thus, a kind of historical

Comment on Carlo Rovelli's "An argument against the realistic interpretation of the wave function"

Rovelli's argument against the realistic interpretation of quantum states and in favor of an ontology of quantum events is refuted.

Decoherence and the Foundations of Quantum Mechanics

This is an introduction to decoherence with an emphasis on the foundational and conceptual aspects of the theory. It explores the extent to which decoherence suggests a solution to the measurement

A simple model of quantum trajectories

Quantum trajectory theory, developed largely in the quantum optics community to describe open quantum systems subjected to continuous monitoring, has applications in many areas of quantum physics. I

Quantum Trajectories: Dirac, Moyal and Bohm

We recall Dirac's early proposals to develop a description of quantum phenomena in terms of a non-commutative algebra in which he suggested a way to construct what he called quantum trajectories.



On the interpretation of measurement in quantum theory

It is demonstrated that neither the arguments leading to inconsistencies in the description of quantum-mechanical measurement nor those “explaining” the process of measurement by means of

Comment on "Unified dynamics for microscopic and macroscopic systems"

  • 1987
A nonunitary dynamics for a macroscopic object arises as a natural consequence of a universally valid Schr\"odinger equation and thus need not be postulated ad hoc and does not allow one to deduce classical states without invoking additional principles.

The roles of decoherence and environment–induced superselection in the emergence of the classical from the quantum substrate are described. The stability of correlations between the einselected

Bound state excitation, nucleon decay experiments and models of wave function collapse.

It is shown how these experimental results could be considered to rule out the original version of the collapse models, and support a version in which the rate of collapse is proportional to the mass, indicative of a gravitational mechanism.

Reduction of the state vector by a nonlinear Schrödinger equation

It is hypothesized that the state vector describes the physical state of a single system in nature. Then it is necessary that the state vector of a macroscopic apparatus not assume the form of a
