Abstract

Remarks on Interpretation, Confirmation and Progressiveness of Early Matrix Mechanics. Our note discusses a case study in view of questions of theory-choice. We examine the extent to which the first 'complete, consistent exposition' of matrix mechanics in 1925 can be claimed to be reasonably confirmed, well interpreted and fruitful. Various strategies, by means of deductions and otherwise, by Born, Jordan and Heisenberg to establish these claims are critically assessed. It is shown that the outcome of the Bothe-Geiger experiment does not represent a 'direct' confirmation of the theory. Finally we pose the question of progressiveness and argue for a low over-all 'problem-solving effectiveness'
