On a possible generalization of modern quantized field theory

Holger Lyre

Carl Friedrich von Weizsaecker's thinking has always crossed the borders between physics and philosophy. Being a physicist by training he still feels at home in the physics community, as a philosopher by passion, however, his mind cannot stop thinking at the limits of physics. His physical ideas are based on the general conceptual and methodological preconditions of physical theories. Such a line of reasoning about the foundations of physics has brought Weizsaecker into an abstract program of a possible reconstruction of physics in terms of yes-no-alternatives, which he called "ur-theory." I shall start this paper with a review of the basic ideas of ur-theory: the definition of an ur and the connection between ur-spinors and spacetime. I then go over to some of ur-theory's present borders: the construction of quantized spacetime tetrads and the difficulties to incorporate gravity and gauge theories. Finally, I shall discuss the possible prospects of ur-theory -- partly with a view to modern quantum gravity approaches, but mainly in connection with its philosophical implications. Here, one of the crucial questions is, whether form, or, modern, information is an entity per se and what particular consequences this may have.

I propose a conceptual change in the way we teach nonrelativistic quantum physics in introductory survey courses and general modern physics courses. Traditional instruction treats radiation as a quantized electromagnetic wave that, because it is quantized, is observable only as discrete field quanta, while treating matter as particles that are accompanied by a wave function. In other words, traditional instruction views radiation as fundamentally a field phenomenon, and matter as fundamentally a particle phenomenon. But quantum field theory has a more unified view, according to which both radiation and matter are continuous fields while both photons and material particles are quanta of these fields. The quantum field theory view of radiation and matter clarifies particle identity issues, dispels students’ Newtonian misconceptions about matter, arguably resolves the wave-particle paradox, is the accepted view of contemporary physics, and might be the simplest and most effective teaching approach for all students. I propose that we make this field-theory viewpoint the conceptual basis for teaching non-relativistic quantum physics.

The work on correcting the historically layered errors of Quantum Theory," in addition to its specific corrections, provided both an understanding of the reasons for their occurrence and why they were canonized. And, also, it became obvious that the Scientific Misconceptions, both included in the modern "Quantum Theory" and in Einstein's SRT, have a General Character. Therefore, the Unified Theory, as has now become obvious, can and, initially, must be built on the General INVARIANTS of Quantization and the Principle of Relativity, while each of the noted Theories proceeds from the use of an individual non-invariant set of orts, plugging the "holes of theories" with EXCLUSIVITIES. This work is devoted to their identification and elimination, which will help correct both the FOUNDATIONS of the Theory of Relativity and will complement the corrections of the FOUNDATIONS of Quantization.
