Time Symmetry and the Theory of Measurement

  • K. Datta


I have chosen to speak on a problem which has been with us since the birth of quantum mechanics. On the one hand this has the advantage that much concerning this problem is part of the general education of a physicist and and it is possible to draw on a large body of earlier work; this report will, in large measure, be in the nature of a review. On the other hand, I shall have to conclude with the confession that inspite of some progress, the problem remains, in many important respects, unsolved.
