What’s the fundamental principle of quantum physics?

Making sense of quantum mechanics. Welcome to the Making sense of Quantum Mechanics research project, a subproject of the Theory of Everything Project.

You will have to brace yourselves for this – not because it is difficult to understand, but because it is absolutely ridiculous: All we do is draw little arrows on a piece of paper – that’s all! Richard P. Feynman, QED: The Strange Theory of Light and Matter (Princeton Science Library), 1985.

Title: Origins Science Scholars Program \”Principles of Quantum Mechanics\”


Quantum Mechanics is the cornerstone of physical theories dealing with the most fundamental issues of nature. Its principles appear to be different from classical laws of nature. This research project aims to make sense of this arduous field, privileging multiple points of view and developing intuitive approaches and insights. It is hoped that putting Quantum Mechanics in such a perspective may facilitate comprehension of the laws governing the elementary constituents of nature.

(PDF) Specker’s fundamental principle of quantum mechanics

I draw attention to the fact that three recently proposed physical principles, namely “local orthogonality”, “global exclusive disjunction”, and “compatible orthogonality” are not new principles, but different versions of a principle that Ernst Specker noticed long ago. I include a video of Specker stating this principle in 2022 in the following terms: “Do you know what, according to me, is the fundamental theorem of quantum mechanics? (…) That is, if you have several questions and you can answer any two of them, then you can also answer all of them”. I overview some results that suggest that Specker’s principle may be of fundamental importance for explaining quantum contextuality. Specker passed away in December 10, 2022, at the age of 91.

Quantum Physics Basic Principles: Discover the Most Mind Blowing Theories That Govern the Universe and the World Around Us (Hardcover)

Is it Really Possible to make Laws of Attraction Work for you? Win the trust of your customers with this Original BookDo you want to see the Applications of Quantum Physics in the Real World and Universe? While physics does play a role in our lives, most of it involves things we don’t think about. For example, physics helps to define how our world is put together on the molecular level. Understanding that enabled them to split atoms and use various waves to transmit information via data and sound. At the same time, it’s interesting to look at how physics can be used to help us understand dimensions, even the ones that might not be easily found or seen. Various aspects of physics have been used in cosmology. This book covers the following topics: – Before Quantum Physics: Light and Matter;- Deep through the Theory of Relativity;- Was Einstein correct about Entanglement?- Why Max Planck is considered the father of Quantum Theory?- Are Dark Matter and Black Hole related?- The 18 biggest unsolved Mysteries in Physics;- Exactly What Is Time?

Experimental Confirmation of the Fundamental Principle of Wave-Particle Duality

Complementarity relation of wave-particle duality is analyzed quantitatively with entangled photons as path detectors. The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented tec.

Richard Feynman once mentioned that solving the puzzle of quantum mechanics is based on the knowledge of the double-slit experiment. It’s anticipated the interpretation in line with the double-path interferometry experiments with ENBS may have fundamental implications for much better comprehending the principle of complementarity and also the wave-particle duality relation quantitatively.

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented technologies which include quantum information, quantum communication, quantum metrology, quantum imaging, and quantum sensing. However, in quantum science, there are still unresolved and even inapprehensible issues like wave-particle duality and complementarity, superposition of wave functions, wave function collapse after quantum measurement, wave function entanglement of the composite wave function, etc.

The inaccessibility to the experimenter agent of the complete quantum state is well-known. However, decisive answers are still missing for the following question: What underpins and governs the physics of agent inaccessibility? Specifically, how does nature prevent the agent from accessing, predicting, and controlling, individual quantum measurement outcomes? The orthodox interpretation of quantum mechanics employs the metaphysical assumption of indeterminism-‘intrinsic randomness’-as an axiomatic, in-principle limit on agent-quantum access. By contrast, ontological and deterministic interpretations of quantum mechanics typically adopt an operational, in-practice limit on agent access and knowledge-‘effective ignorance’. The present work considers a third option-‘objective ignorance’: an in-principle limit for ontological quantum mechanics based upon self-referential dynamics, including undecidable dynamics and dynamical chaos, employing uncomputability as a formal limit. Given a typical quantum random sequence, no formal proof is available for the truth of quantum indeterminism, whereas a formal proof for the uncomputability of the quantum random sequence-as a fundamental limit on agent access ensuring objective unpredictability-is a plausible option.

1.4: Principles of Quantum Mechanics

Here we will continue to develop the mathematical formalism of quantum mechanics, using heuristic arguments as necessary. This will lead to a system of postulates which will be the basis of our subsequent applications of quantum mechanics.

The word orthogonal has been utilized for both verticle with respect vectors as well as for functions whose product integrates to zero. This really connotes an in-depth link between vectors and processes. Consider two orthogonal vectors a and b. Then, when it comes to their x, y, z components, labeled by 1, 2, 3, correspondingly, the scalar product could be written.

Postulates of Quantum Mechanics

An operator represents a prescription for turning one function into another: in symbols, \(\hat{A}\psi=\phi\). From a physical point of view, the action of an operator on a wavefunction can be pictured as the process of measuring the observable \(A\) on the state \(\psi\). The transformed wavefunction \(\phi\) then represents the state of the system after the measurement is performed. In general, \(\phi\) is different from \(\psi\), consistent with the fact that the process of measurement on a quantum system produces an irreducible perturbation of its state. Only in the special case that \(\psi\) is an eigenstate of \(A\), does a measurement preserve the original state. The function \(\phi\) is then equal to an eigenvalue \(a\) times \(\psi\).

Fundamental principles of quantum theory – After introducing general versions of three fundamental quantum postulates—the superposition principle, the uncertainty principle, and the complementarity principle—we discuss the question of whether the three principles are sufficiently strong to restrict the general Mackey description of quantum systems to the standard Hubert-space quantum theory. We construct an example which shows that the answer must be negative. We introduce also an abstract version of the projection postulate and demonstrate that it could serve as the missing physical link between the general Mackey description and the standard quantum theory.

Seven Essential Elements of Quantum Physics

The previous collection of things everyone should know about quantum physics is a little meta– it’s mostly talking up the importance and relevance of the theory, and not so much about the specifics of the theory. Here’s a list of essential elements of quantum physics that everyone ought to know, at least in broad outlines:

4) Measurement determines reality. Before the moment the exact condition of the quantum particle is measured, that condition is indeterminate, and actually could be regarded as disseminate total the potential outcomes. Following a measurement is created, the condition from the particle is completely determined, and all sorts of subsequent measurements with that particle will return produce the identical outcome.

1) Particles are waves, and vice versa. Quantum physics tells us that every object in the universe has both particle-like and wave-like properties. It’s not that everything is really waves, and just sometimes looks like particles, or that everything is made of particles that sometimes fool us into thinking they’re waves. Every object in the universe is a new kind of object– call it a “quantum particle” that has some characteristics of both particles and waves, but isn’t really either.
