Quantum Theory and Time Asymmetry

The relation between quantum measurement and thermodynamically irreversible processes is investigated. The reduction of the state vector is fundamentally asymmetric in time and shows an observer-relatedness which may explain the double interpretation of the state vector as a representation of physical states as well as of information about them. The concept of relevance being used in all statistical theories of irreversible thermodynamics is shown to be based on the same observer-relatedness. Quantum theories of irreversible processes implicitly use an objectivized process of state vector reduction. The conditions for the reduction are discussed, and I speculate that the final (subjective) observer system might even be carried by a spacetime point.Comment: Latex version of a paper published in 1979 (with minor revisions), 18 page

The longest note of the xylophone was 35 inches and the shortest 24 inches, the average widith of each note was 3 and a half in. A servant of the chief placed himself at one end of the instrument to put his hand in under the notes and slide back into place any note which began to slip. The scale was:- 464, 396. 360, 308, 264, 232 v.s. 464 and 232 representing the third and eighth notes on this instrument. All the others in corresponding octaves. Instrumental tune, with 1 Madinda xylophone, 12 loose notes, supported on banana stalks
