Theoretical physics, Heidegger once said, “is the proper, pure technology.” To understand what he meant, we need to remember that he first presented “The Question Concerning Technology” in the form of a lecture delivered at a conference as part of a critical exchange with the theoretical physicist Werner Heisenberg. According to Heisenberg, quantum theory radically altered the image of nature informing classical physics. With the discovery of quantum indeterminacy, he maintained, “for the first time in the course of history man on earth faces only himself.” Heidegger insists, on the contrary, that modern physics constitutes no essential change in the metaphysical conception of nature that arose in the early modern age, namely the aspiration to a maximally correct mathematical representation and ordering or “enframing” of entities as a whole. In spite of its mathematical rigor and objective correctness, however, contemporary physics cannot grasp nature in all its intractable, inexhaustible complexity. Nature qua physis remains, he says, “uncanny.” To suppose that quantum theory represents not just our most fundamental knowledge of nature, but moreover an authentic encounter with ourselves, is to forget the mystery and obscurity essential to our primordial relation to being understood as physis .

In classical physics there is, in accordance with common sense, an objective world ‘out there’. That world evolves in a clear and deterministic way, being governed by precisely formulated mathematical equations. This is as true for the theories of Maxwell and Einstein as it is for the original Newtonian scheme. Physical reality is taken to exist independently of ourselves; and exactly how the classical world ‘is’ is not affected by how we might choose to look at it. Moreover, our bodies and our brains are themselves to be part of that world. They, also, are viewed as evolving according to the same precise and deterministic classical equations. All our actions are to be fixed by these equations - no matter how we might feel that our conscious wills may be influencing how we behave. Such a picture appears to lie at the background of most serious 1 philosophical arguments concerned with the nature of reality, of our conscious perceptions, and of our apparent free will. Some people might have an uncomfortable feeling that there should also be a role for quantum theory - that fundamental but disturbing scheme of things which, in the first quarter of this century, arose out of observations of subtle discrepancies between the actual behaviour of the world and the descriptions of classical physics. To many, the term ‘quantum theory’ evokes merely some vague concept of an ‘uncertainty principle’, which, at the level of particles, atoms or molecules, forbids precision in our descriptions and yields merely probabilistic behaviour. Actually, quantum descriptions are very precise, as we shall see, although radically different from the familiar classical ones. Moreover, we shall find, despite a common view to the contrary, that probabilities do not arise at the minute quantum level of particles, atoms, or molecules - those evolve deterministically - but, seemingly, via some mysterious larger-scale action connected with the emergence of a classical world that we can consciously perceive. We must try to understand this, and how quantum theory forces us to change our view of physical reality.
Abstract Quantum physics represents one of the most significant intellectual achievements of modern science, reshaping humanity’s understanding of nature at its most fundamental level. It provides the conceptual and mathematical foundations for explaining atomic structure, radiation, and the behavior of particles, forces, and materials, while underpinning many contemporary technologies. Yet its development was marked by profound conceptual disruption. From its earliest formulations, quantum theory challenged classical assumptions about determinism, causality, and certainty, generating paradoxes and disagreements even among its founders. In exploring the universe, quantum physics focuses on the smallest constituents of matter such as quarks, electrons, and photons, revealing a domain that consistently defies everyday intuition. Within this realm, particles exhibit wave–particle duality, physical outcomes are described probabilistically, and measurement plays a constitutive role in determining observable reality. Although such phenomena may appear extraordinary, physicists have rendered them intelligible through rigorous theoretical frameworks and precise mathematical formalism. Within a scientific context, the “truth” of quantum mechanics does not imply metaphysical finality, but rather its exceptional capacity to describe, explain, and predict experimental results with remarkable accuracy. Importantly, this scientific account need not contradict spiritual or religious perspectives. Instead, by unveiling the coherence and complexity of the universe, quantum physics can complement scriptural narratives that emphasize meaning and purpose. This study investigates the scientific truth and narrates the story of universe on the basis of quantum physics and explores its influences on technological development and reshaping the civilization.
The classical physical science distinguishes itself as a previous project, consisting of the fundamental concepts of elements such as calculation, time, space, motion, matter, force and directed to capture all the nature phenomena supposedly unified. Quantum mechanics advances beyond these postulates, evidencing the inevitable interference of the subject in the search results , in which a reference to an ontological theory with material objects should be able to capture for regularities calculation, it becomes impossible, leaving the core concepts and field for the previous innovative project. As a result, the uncertainty principle that is expressed in a state of motion is identified only as to the statistical calculation or position, or the magnitude of the movement. After the development the existential concept of science that emphasizes the being-there as being-in-the-world to find certain beings as objects by the previous project of the scientific perspective, Heidegger subsequently comes to the conclusion that quantum physics incorporating the classical physics keeps unchangeable in terms of the previous science project of all: the nature disposes in advance a way of securing the meeting proposed by the existing human scientific achievement in theory terms . Science is only an access way to nature in its inexhaustible plenitude, so that it makes it unavoidable and unattainable with the scientificity resources. The com-position is the essence of the technique using scientific results and, by its vortex, enabling it to the final co-existing human. It remains to the being-there the mercy of a thought as to question the destitute condition of his own danger in forgetting that the cooption may be victim of their own decision.
Introduction Chapter 1 dealt with one of the deepest mysteries in modern science: how to explain consciousness. This Part deals with another mystery: how to make sense of quantum mechanics. Both involve a problem of reconciliation with the classical worldview, which is one hint that the two mysteries might be related. A second is that, unlike classical physics, which makes no reference to or allowance for consciousness, quantum theory raises the issue of consciousness and its relationship to the physical world in a very direct way. These hints do not necessarily mean there is a connection between the two mysteries, but by the end of this Part I hope to have shown why it would be natural to look for one. My more immediate aim here is to give the social scientific reader an introductory understanding of the experimental findings of quantum theory, its key concepts, and the debates about its interpretation. The discussion assumes no prior knowledge of quantum physics and makes no use of mathematics. Quantum theory without equations might seem like an oxymoron, and certainly reading this Part will not enable anyone to use quantum theory. But to a perhaps surprising degree it is possible to understand quantum theory without being able to use it. Its findings can be communicated in ordinary language, and the same goes for its main concepts and interpretive debates. One consequence of this has been the emergence of a virtual cottage industry of books on quantum theory for a lay audience. Most are written by physicists, and many are quite good. However, it is not just popular treatments that do without equations: much of the professional philosophical literature does as well. (I draw on both kinds of literature below.) Philosophers of physics are trained to understand the math, of course, which is necessary for a full appreciation of the issues.
[I] think I can safely say that nobody understands quantum mechanics. Richard Feynman, The Character of Physical Law Quantum mechanics [is] that mysterious, confusing discipline, which none of us really understands but which we know how to use. It works perfectly, as far as we can tell, in describing physical reality, but it is a ‘counter-intuitive discipline’… Murray Gell-Mann, Questions for the Future [The quantum] postulate implies a renunciation as regards the causal space-time co-ordination of atomic processes. Niels Bohr, Atomic Theory and the Description of Nature It should be emphasized, however, that the probability function does not in itself represent a course of events in the course of time. It represents a tendency for events and our knowledge of events. The probability function can be connected with reality only if one essential condition is fulfilled: if a new measurement is made to determine a certain property of the system. [T]he idea of an objective real world whose smallest parts exist objectively in the same sense as stones or trees exist, independently of whether or not we observe them…is impossible … Werner Heisenberg, Physics and Philosophy [In] quantum theory it is the principle of causality , or more accurately that of determinism , which must be dropped and replaced by something else.… We now have a new form of the law of causality.… It is as follows: if in a certain process the initial conditions are determined as accurately as the uncertainty relations permit, then the probabilities of all possible subsequent states are governed by exact laws. Max Born, The Restless Universe
The odd concepts of quantum physics are nearly a century old. They may seem difficult and forbidding at first sight, but the barrier to understanding is not their difficulty but their differentness . Unlike classical models, quantum theory does not attempt to simulate Nature. It gives us information about observations of Nature. But it does contain a “theoretical entity” that claims to contain all information, observation notwithstanding, namely the quantum state vector in Hilbert space. Scientists routinely use the language of Hilbert space, and nonscientists do not use it at all, which is understandable but unfortunate. A sort of baby-talk has become the lingua franca for much of the popular journalism of quantum physics, an awkward patois that combines some of the early groping language of Bohr, de Broglie, Schrödinger, and Heisenberg with more modern words about symmetries and states. Earnest amateurs still ask me about the mystery of Bohr orbits. There is no mystery because there are no orbits, except as historical curiosities. Same for “wave–particle duality.” Same for “quantum jumps.” A friend once asked me to address a philosophy seminar about the “paradoxes of quantum mechanics.” He said he had approached C. N. Yang first, who replied “What paradoxes?” There are some mathematical and logical rough spots in our current best theory of matter, and perhaps some of them can be framed as paradoxes. But the theory is actually rather straightforward, and it has a perfectly clear interpretation linked to experiments that, in their simplest form, anyone can perform (and students do routinely in college laboratories). No empirical observations are known that are inconsistent with the quantum framework.
