"The Quest for Understanding in Relativistic Quantum Physics":
The paper discusses the status and some perspectives of relativistic quantum physics as anticipated in 1999.
Authors' statement in the introduction: "Still there was the empirical
fact that QED was capable of producing numbers agreeing with experiments
to an unbelievable degree of accuracy without any radical changes in its foundations and that there lacked any indication that the general scheme of quantum field theory was at odds with experiments in high energy physics, though there were obviously great difficulties in eliminating conceptual and mathematical muddles abounding in the existing formulation. So it appeared that the time called for a period of consolidation, of patient work devoted to the separation of golden nuggets from the mud. What constitutes a quantum field theory? What is needed to extract the relevant physical information?"
