A brief review of the main ideas (interpretations) of quantum mechanics is given. Each of the considered interpretations contains a number of disputable provisions, the discussion of which allows us to develop our own understanding of the mechanism of paradoxical quantum phenomena. The article is addressed to all students who study the concepts of modern natural science, and to all readers interested in the questions what is the reality beyond the quantum mechanical experiment or if our perception really shapes the physical world in some way.

A brief review of basic concepts (interpretations) of quantum mechanics is given. Each of the above interpretations has a number of controversial points, which allow discussion to develop their understanding of the mechanism of the paradoxical quantum phenomena. The article is written for students-economists studying the concepts of modern science and all readers interested in the questions: what is beyond the reality of the quantum-mechanical experiment or does our perception create, in some sense, the physical world. The author believes that the development of quantum information technology is impossible without an answer to these fundamental questions.
Quantum mechanics is one of the most significant scientific theories in modern physics, concerned with the behavior of matter and energy at the atomic and subatomic scales. By introducing concepts such as the quantization of energy, wave–particle duality, the uncertainty principle, quantum superposition, and quantum entanglement, this theory has fundamentally transformed humanity's understanding of the underlying structure of the universe. The importance of studying quantum mechanics lies not only in its ability to explain the fundamental phenomena of nature but also in its extensive contribution to the development of advanced technologies, including quantum computing, medical imaging, laser technology, secure communications, and nanotechnology. The objective of this article is to examine the fundamental principles of quantum mechanics and analyze their applications across various scientific and technological fields. This study employs a library-based research method with a descriptive–analytical approach. The required data were collected and analyzed through an extensive review of books, peer-reviewed scientific articles, and other authoritative sources in the field of quantum physics. The findings indicate that quantum mechanics, in addition to playing a fundamental role in understanding the subatomic world, constitutes one of the principal foundations for the advancement of modern technologies. Furthermore, the results suggest that the continued development of quantum technologies has the potential to exert profound impacts on scientific, industrial, and medical fields in the future. Consequently, quantum mechanics is not merely a fundamental physical theory but also a key driver of innovation and transformation in contemporary science and technology.
Scope of this book Quantum mechanics is a difficult subject, and this book is intended to help the reader overcome the main difficulties in the way to understanding it. The first part of the book, Chs. 2–16, contains a systematic presentation of the basic principles of quantum theory, along with a number of examples which illustrate how these principles apply to particular quantum systems. The applications are, for the most part, limited to toy models whose simple structure allows one to see what is going on without using complicated mathematics or lengthy formulas. The principles themselves, however, are formulated in such a way that they can be applied to (almost) any nonrelativistic quantum system. In the second part of the book, Chs. 17–25, these principles are applied to quantum measurements and various quantum paradoxes, subjects which give rise to serious conceptual problems when they are not treated in a fully consistent manner. The final chapters are of a somewhat different character. Chapter 26 on decoherence and the classical limit of quantum theory is a very sketchy introduction to these important topics along with some indication as to how the basic principles presented in the first part of the book can be used for understanding them. Chapter 27 on quantum theory and reality belongs to the interface between physics and philosophy and indicates why quantum theory is compatible with a real world whose existence is not dependent on what scientists think and believe, or the experiments they choose to carry out. The Bibliography contains references for those interested in further reading or in tracing the origin of some of the ideas presented in earlier chapters.
Quantum physics is the golden child of modern science. It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behavior of materials. But for a century it has also been the problem child of science as it has been overwhelmed by intense disagreements between its inventors, strange paradoxes, and implications that seem like the stuff of fantasy. To understand the universe, quantum physics explores the behavior of the smallest particles in existence like quarks, electrons, and photons and which revealing a world that defies our everyday experiences and expectations. On the other hand, quantum mechanics (QM) is a fundamental theory in physics that describes the behavior of matter and energy at the atomic and subatomic levels, where classical physics fails to apply. However, the phenomena observed in QM can seem nothing short of miraculous. Physicists are trying to explain miracles of physics of universe meticulously which governed by precise scientific principles and mathematical equations. It is serious to modern technology, as its principles as well as wave-particle duality, superposition, and entanglement form the basis for electronics, computing, and medical technologies. The truth of QM in a scientific context refers to its exceptional ability to accurately describe and predict experimental results, not a philosophical ‘absolute truth’. Interestingly, the scientific elucidation of creation through quantum physics does not refute and contradict spiritual or religious narratives, rather augments our gratitude of the universe’s complexity and towards Almighty or Creator. The Bible’s or Quran’s account of creation provides a spiritual and philosophical outlook, accentuating purpose and intentionality. The precise explanations of particle behavior and cosmic formation in quantum physics, offers a balancing view grounded in empirical evidence. The purpose of this investigative study is to explore the scientific reality of QM and its purpose to depict the technical advancement for the development of modern civilization along with understand of universe in more logical way.
Abstract This chapter surveys various proposals to interpret—that is, make sense of—quantum mechanics. We could attempt to think of quantum mechanics in purely instrumentalist terms, as an algorithm to predict observed experimental results. But this fits badly with scientific practice and is probably not viable. We could attempt to modify quantum mechanics itself to resolve the paradoxes, and there are some simple models that attempt to do that: some are ‘hidden-variable’ theories that add extra properties to the theory, some are ‘dynamical-collapse’ theories that modify the theory’s equations. But none of these models succeed in reproducing quantum theory’s predictions outside a relatively narrow range of applications. Or we could try to take the apparent indefiniteness of quantum mechanics literally, and interpret it as a theory of many parallel worlds. The correct interpretation of quantum mechanics remains controversial, but the search for understanding and interpretation of the theory has led to very substantial scientific results and is likely to lead to more.
The book presents a multidisciplinary analysis of the context of quantum physics experiments and the function of the human mind that makes it possible to demonstrate that an object-based model of reality formed at the level of the unconscious is the basis of our worldview. The consciousness experiences a ''time flow'' because of the specific features of perception in the form of a model with a sequential fixation of events. Together with the need to relate objects in terms of the model, this generates a space-time representation of the world around us. Acceptance of a mental character of our construct of reality allows for resolution of the problems in quantum physics and its paradoxes, thereby opening the way to an insight into reality. The presented material is organized in a specific order to facilitate the reader's understanding. First, the fact that if there are no objects in the area of quantum mechanics, then they belong to the corresponding model rather than the reality is proved by case studies of the most discussed and relevant paradoxes of quantum physics. The authors consider a topological variant in constructing an object-based space that describes the physical properties of an object that are the most verified in science and describable with mathematical relations. The functionality of the proposed construct is tested by deriving the ''laws'' of conservation of energy and momentum in a relativistic form. The book is oriented towards experts in physics and psychology, advanced students, and readers interested in state-of-the-art science and the philosophy connected to it.
