Correspondence on the ‘Einstein Paradox’

Guido Bacciagaluppi, Elise Crull

This chapter presents a collection of letters between the main protagonists in the EPR debate as analysed in the present volume. Among many other letters, it includes the first ever complete English translation of the correspondence Schrödinger held concerning the EPR paper with, e.g., Einstein, Bohr, Pauli, Born and Teller. He kept these letters in a special folder labelled ‘The Einstein Paradox’, only a small portion of which has previously been discussed in the foundations literature. These historical documents, many of which are published here for the first time, form the basis of our analysis in the beginning chapters of this book.This chapter presents a collection of letters between the main protagonists in the EPR debate as analysed in the present volume.

Others on EPR

Guido Bacciagaluppi, Elise Crull

This chapter provides a complete list and brief analyses of published and unpublished responses to EPR in 1935 (virtually all of which are reprinted as later chapters in this book). We invite a renewed consideration of certain contributors not much discussed elsewhere in the literature. These include going beyond Kemble’s short criticism of EPR to his ensuing disagreement with Margenau about the viability of an ensemble interpretation of the wavefunction, and also a response to Kemble’s note on EPR by Podolsky himself. We also examine the correspondence between Margenau and Einstein in the wake of EPR, discussing the role of the collapse postulate, and finally we discuss two papers by Furry, which although not entirely satisfactory qua a response to EPR’s arguments, are nevertheless of great potential interest for the foundations literature more generally.This chapter provides a complete list and brief analyses of published and unpublished responses to EPR in 1935 (virtually all of which are reprinted as later chapters in this book).

Quantum Mechanics and Physical Reality

Guido Bacciagaluppi, Elise Crull

This is a reprinting of Bohr’s note to Nature advertising his forthcoming response to the EPR paper. It is very brief but contains in essence the argumentative tack Bohr would in fact employ in his full response to EPR.

The Quantum Measurement Problem

A. J. Leggett

Despite the spectacular success of quantum mechanics (QM) over the last 80 years in explaining phenomena observed at the atomic and subatomic level, the conceptual status of the theory is still a topic of lively controversy. Most of the discussion centers around two famous paradoxes (or, as some would have it, pseudoparadoxes) associated, respectively, with the names of Einstein, Podolsky, and Rosen (EPR) and with Schrodinger's cat. In this Viewpoint, I will concentrate on the paradox of Schrodinger's cat or, as it is often known (to my mind somewhat misleadingly), the quantum measurement paradox.Despite the spectacular success of quantum mechanics (QM) over the last 80 years in explaining phenomena observed at the atomic and subatomic level, the conceptual status of the theory is still a topic of lively controversy.

Quantum Mechanics as a Physical Theory

Guido Bacciagaluppi, Elise Crull

This is a reprinting of Flint’s response to EPR, originally signed only as ‘H.T.F.’ Flint begins with a fairly accurate outline of the argument in the EPR paper – with which he agrees – but then he expresses doubts as to the validity of the reality criterion. Without describing the nature of these doubts, he concludes by further agreeing with EPR in desiring a more direct description of reality than the one currently provided by quantum mechanics.
