"Objective vs Subjective Probability," handwritten draft, 1955

Hugh Everett

Published May 20, 2011• 0 citations

Abstract

Before writing a first draft of the long thesis, Hugh Everett wrote three short papers, often refered to as his minipapers, for John Wheeler to review. This minipaper, called "Objective vs. Subjective Probability," presents an early formulation of the quantum measurement problem in terms of a conflict between subjective and objective probabilities. Everett ultimately provided a much clearer formulation of the measurement problem in terms of a conflict between different state attributions in the long thesis. The structure of the experimental setup, however, is similar. There are two versions of this minipaper. The present document is an early handwritten draft. It was found in a file labeled "Early drafts," among Everett's papers.

"Probability in Wave Mechanics," handwritten draft, 1955

Hugh Everett

Before writing a first draft of the long thesis, Hugh Everett wrote three short papers, often refered to as his minipapers, for John Wheeler to review. This minipaper, ultimately called "Probability in Wave Mechanics," develops the basic premise of Everett's thesis stripped of its formalism, but laced with explanatory metaphors, such as splitting amoebas that share overlapping memories until diverging into separate futures recorded as consistent histories. There are several handwritten drafts of this minipaper and two typed versions, one turned into Wheeler. The present document is one of the handwritten documents, found in the early drafts file.

"Quantitative measure of correlation," minipaper, 1955

Hugh Everett

Before writing a first draft of the long thesis, Hugh Everett wrote three short papers, often refered to as his minipapers, for John Wheeler to review. This minipaper, called "Quantitative measure of correlation," lays some groundwork for the application of information theory as a measure of the degree of quantum correlation or entanglement. From very early in the project, Everett thought that Shannon information theory would provide insight into pure wave mechanics. While statistical measures, such as standard deviation, would have sufficed, Everett developed information-theoretic measures to represent such things as the width of distributions and the degree of correlation between the states of multiple systems. He thought that the standard quantum uncertainty relations were best expressed in an information theoretic way. The present document is the typed version of the minipaper that Wheeler would have seen and commented on.
