Quantum mechanics once more
Quantum mechanics once more by Marek Ożarowski, Tom Wawer (We’ve finded this information by Generative artificial intelligence - Wikipedia).
The topic of Quantum mechanics seems to be interesting. However, it did not appeal to everyone. Albert Einstein never expressed his approval in the area of quantum mechanics. Today we have plenty of evidence that he was, in fact, very wrong. Of course, we have a lot of uncertainty and doubt about quantum mechanics itself. We still don't know how to combine gravity into Quantum mechanics - that seems to be the biggest challenge at the moment.
Perhaps we will soon reach a sufficient level of technology and acquire knowledge that will solve the problems of quantum mechanics. But another scenario may follow. Just as classical mechanics has been supplanted by Quantum mechanics, a physics adequate to future technologies may emerge. This new physics may be an extension of both classical physics and quantum mechanics. Quantum mechanics will still be a long time to meet the expectations of scientists, there will still be funding and research in the area of quantum mechanics.
Thus, it seems that our search for information about Quantum mechanics has its justification. We are therefore publishing what we have been able to obtain using AI. Of course, at the end we have a discussion about our interpretation of phenomena at the quantum level. This is our interpretation of quantum mechanics, and perhaps a new, adequate philosophy of physics. This is an invitation to discuss a difficult and non-obvious topic.
The Wiki's information about Quantum mechanics
Quantum mechanics is the fundamental physical theory that describes the behavior of matter and of light; its unusual characteristics typically occur at and below the scale of atoms. It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales.
Quantum systems have bound states that are quantized to discrete values of energy, momentum, angular momentum, and other quantities, in contrast to classical systems where these quantities can be measured continuously. Measurements of quantum systems show characteristics of both particles and waves (wave–particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle).
Quantum mechanics arose gradually from theories to explain observations that could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and the correspondence between energy and frequency in Albert Einstein's 1905 paper, which explained the photoelectric effect.
These early attempts to understand microscopic phenomena, now known as the "old quantum theory", led to the full development of quantum mechanics in the mid-1920s by Niels Bohr, Erwin Schrödinger, Werner Heisenberg, Max Born, Paul Dirac and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical entity called the wave function provides information, in the form of probability amplitudes, about what measurements of a particle's energy, momentum, and other physical properties may yield.

Peeking Behind the Curtain: A Gentle Introduction to Quantum Theory
Imagine the world around you, from the smallest speck of dust to the vast expanse of galaxies. For centuries, classical physics, the kind Isaac Newton laid the groundwork for, provided a seemingly complete and accurate description of how things work. It painted a picture of a predictable universe where objects followed well-defined paths and their properties could be known with certainty. But as scientists peered deeper into the realm of the incredibly small – the world of atoms and the particles that make them up – a strange and wonderful new reality began to emerge: quantum theory.
Quantum theory, born in the early 20th century from the groundbreaking work of Max Planck, Albert Einstein, Niels Bohr, and many others, revolutionized our understanding of the fundamental building blocks of the universe. It revealed a world that is not smooth and continuous like a flowing river, but rather grainy and discrete, like individual droplets of water. This "graininess" is where the term "quantum," meaning a discrete packet or unit, comes from.
Energy Comes in Chunks: The Quantum Leap
One of the earliest and most startling discoveries was that energy isn't infinitely divisible. Instead, it comes in tiny, specific amounts called quanta. Think of it like climbing a staircase; you can only stand on specific steps, not in between. Similarly, atoms can only absorb or emit energy in these discrete packets. This idea, first proposed by Planck to explain the spectrum of light emitted by heated objects (blackbody radiation), was a radical departure from classical physics, which assumed energy could take on any value.
Einstein further solidified this concept when he explained the photoelectric effect – the emission of electrons from a metal surface when light shines on it. He proposed that light itself is also quantized, existing as tiny packets of energy called photons. The energy of a photon is directly proportional to its frequency, a relationship famously expressed as:
This simple equation has profound implications, suggesting that light, which was long thought to be a continuous wave, also has particle-like properties.
Particles Acting Like Waves (and Vice Versa!)
Perhaps the most mind-bending aspect of quantum theory is the concept of Wave–particle duality. It turns out that particles like electrons, which we typically think of as tiny balls of matter, can also exhibit wave-like behavior. They can diffract (bend around obstacles) and interfere with each other, just like light waves. Conversely, light, which we know behaves as a wave, can also act as a stream of particles (photons).
This duality isn't a case of something being "either a wave or a particle"; rather, it suggests that these are just two different ways of describing the same fundamental quantum entities, depending on how we observe them.
The Realm of Probability: Saying Goodbye to Certainty
As we've discussed before, quantum theory also introduces an inherent element of probability into our understanding of the universe. Unlike classical physics, which can, in principle, predict the future with perfect certainty if we know the initial conditions, quantum mechanics deals with probabilities. For example, we can't know the exact position and momentum of an electron simultaneously (as dictated by Heisenberg's uncertainty principle). Instead, we can only calculate the probability of finding it in a particular region of space or having a certain momentum.
This probabilistic nature isn't due to our lack of knowledge; it's a fundamental characteristic of the quantum world. The behavior of quantum systems is inherently probabilistic, and our measurements reveal only one of the many possible outcomes.
Why Does Any of This Matter?
You might be wondering why this strange world of quanta and probabilities is important in our everyday lives. The truth is, quantum theory underpins much of modern technology:
- Lasers: Based on the quantized energy levels of electrons in atoms.
- Semiconductors: The foundation of modern electronics, relying on the quantum behavior of electrons in materials.
- Medical Imaging (MRI): Exploits the quantum properties of atomic nuclei.
- Nuclear Energy: Based on the energy released from changes within the atomic nucleus, governed by quantum rules.
Furthermore, quantum theory is the foundation upon which our understanding of the fundamental forces of nature (electromagnetism, strong nuclear force, weak nuclear force) and the particles that mediate them is built. It is essential for understanding the behavior of stars, the formation of elements, and the very early universe.
A Journey of Ongoing Discovery
Quantum theory, while incredibly successful in explaining a vast range of phenomena, is still a field of active research. Scientists continue to explore its deeper implications, grapple with its more counterintuitive aspects, and strive to unify it with our understanding of gravity (leading to theories like quantum gravity and string theory).
Stepping into the world of quantum mechanics is like entering a realm where the familiar rules of our macroscopic world no longer fully apply. It requires us to embrace new ways of thinking about reality, to accept the inherent uncertainties, and to marvel at the strange and beautiful laws that govern the universe at its most fundamental level. While it might seem abstract, quantum theory is not just a theoretical curiosity; it is the key to unlocking the deepest secrets of the cosmos and driving technological innovation.

Interpretation of phenomena at the quantum level according to our concept
The quantum world has its solution at the macro level. What happens at the quantum level has its translation in the Reality around us. So far, phenomena at the micro level are little understood by us. The Uncertainty Principle, Wave-particle duality, or the Schrödinger's cat experience seem foreign to our concept of Reality at the macro level. Our Concept - ToE-Quantum Space has its interpretation of the quantum world.
Our interpretation of the phenomena of quantum mechanics concerns: Bohr's model (see more Bohr model), Wave-particle duality, the Uncertainty Principle. What we present in our articles is our attempt to answer the question: what would happen if our concept of time were expanded? In other words, if our time, from our point of view, is only an incomplete description of the Reality around us, then perhaps is this description could be expanded to include an imaginary part, one could explain phenomena at the micro level in a completely different way.
From our point of view - in our Here and Now, it is not possible to have Schrödinger's cat dead and alive at the same time. At the quantum level, such a possibility is permissible and obvious. Does this mean that the Quantum World has a different passage of time? Or maybe our concept of time is simply incomplete. If Schrödinger's cat can be dead and alive at the same time at the quantum level, then time describing quantum phenomena must be imaginary from our point of view.
The basis of our interpretation of quantum mechanics is a different conception of time. If we are able to conceive of our time as having a different interpretation, then every phenomenon in the micro world also has its own different interpretation. Consequently, phenomena occurring at the macro level also have a different understanding.
