Part II. Basics of Quantum Physics

Biljana Percinkova

A Rradical Theory based on Self-Referenced System underlying physical phenomena is proposed based on finite number of agents and their choices of non denials. The theory proposed resolves the collapse/observer problem in quantum mechanic and basic paradox of Godel’s theorem of incompleteness. The theory is strongly supported by measured parameters in CERN Institute of Particle Physics in Geneva.

By D. ter Haar London: Interscience Publishers, Ltd. Pp. viii + 127. Price 30s. This book surveys the methods which have been applied in the discussion of many-body problems in physics. After an introduction in which the basic ideas are reviewed, Part I deals with methods which try to reduce the problem to one of free particles, while Part II gives a more extensive discussion of recent work on collective behaviour theories, particularly that of Tomonaga and its developments.

Using the simplest possible quantum system—the qubit—the fundamental concepts of quantum physics can be introduced. This highlights the common features of many different physical systems, and provides a unifying framework when teaching quantum physics at the high school or introductory level. In a previous TPT article and in a separate paper posted online, we introduced catchy visualizations of the qubit based on the Bloch sphere or just the unit circle (see also Refs. 3–8 for other approaches highlighting the importance of the qubit). These visualizations open the way to understand basic ideas of quantum physics even without knowledge of the underlying mathematical formalism. In addition, simple mathematics can be introduced to describe the qubit as an abstract object and basic unit of quantum information. This generalizes the digital bit as a basic unit of classical information. The proposed visualizations can be used even at the high school level, while the mathematical explanations are of importance when teaching quantum physics at the undergraduate university level. This approach provides a unified framework to introduce common features of all quantum systems, such as the stochastic behavior and state change of a superposition state under measurement.
