?How did quantum physics bring about scientific revolutions unparalleled in history
Despite the ambiguity of its terminology and the complexities surrounding its ideas, quantum physics has made scientific revolutions unparalleled in history during the past century, and it continues to do so during the current century, and still presents a lot of amazement, to the extent that it makes it seem impossible and sometimes imaginary. And a kind of magic at other times.
However, with the progress of science, quantum mechanics became one of the best scientific theories that ever appeared, which changed our view of the world completely, and also proved the shortcomings and weaknesses of classical physics, just as humans , surrounded by quantum physics, to the extent that its achievements cannot be denied, what is it? Where is it leading us?
The end of the classics
In order to understand or define quantum physics, classical physics must first be defined, the light of which has begun to fade since 1900, and classical physics explains the laws that "restrict the movement of objects with large masses, such as stars, planets, life, and other objects of known mass and limited speed." , and classical mechanics (also known as Newtonian mechanics) gives accurate results and rational numbers, as long as the tested objects have a large mass and their velocity does not reach the speed of light," according to the website of the British Academy of Sciences.
Quantum physics explains the probabilities, energy, and motion of infinitesimal bodies, which classical Newtonian physics cannot.
These laws of physics are mostly simple, and they "treat the various processes and events around us, but they stand helpless in front of describing and testing very small bodies, such as subatomic bodies of protons and neutrons and the like, which approach their speed to the speed of light, and give us inaccurate and illogical results." And here comes the role of quantum mechanics," according to the "Livescience" website.
The website explains; That "on the other hand, quantum mechanics has more complex theories, such as Einstein's theory of relativity, and the theories of scientists (such as: Max Planck, Niels Bohr, Schrödinger, and others), about the contraction and expansion of the universe, and thanks to these theories it became possible to provide more accurate results for tests on objects with Very small sizes, which classical physics cannot provide."
Quantum physics investigates the formation of life and the universe and the possibilities for them to exist in different states at the same time
Quantum mechanics deals with what is called "wave particle duality", molecular and atomic; Einstein's special theory of relativity (1905) deals with objects of small atomic sizes, while Einstein's general theory of relativity (1916) also deals with particles in general, even with particles of relatively large sizes.
It is complex to explain the theories of quantum physics and quantum mechanics in an abstract way. It will not be easy to understand negative gravity, dark energy, and the theory of observing infinitesimal quanta, which are smaller than atoms, and the relationship between light and its speed, and time; Therefore, it would be simpler to take examples of the achievements of quantum physics since its development in the twentieth century, and how humanity lives in its field today.
beginning; Quantum physics is involved in everything; In our smartphones, in computers and their development, in the algorithms of the Internet and artificial intelligence, as well as in space sciences, and in biology, and from the latter was born the quantitative biology that tries to explain life.
?How and Why
The two basic science questions in physics , looking for why the universe came? And how? They are followed by questions such as: When did the universe begin? And when did life begin? And even about what existed before the beginning, with a fervor fueled by quantum physics.
Looking first at quantum biology, as the simplest and most recent application of quantum physics that is still in its infancy stage, based on a “quantum phenomenon called “quantum tunneling” that studies the disappearance of the electron and its appearance elsewhere, bypassing the energy barrier; that is, the electron can He crossed an energy barrier greater than his own energy, which classical physics thought impossible, according to the University of Illinois Biological Physics website.
Quantum physics intervenes in consciousness and suggests that a potential world may be in many different states at the same time
for example; Quantitative biology can give an explanation for the occurrence of mutations. Deoxyribonucleic acid, known as DNA, which carries the genes that determine the characteristics of any living organism, is in the form of a spiral ribbon. The situation can be imagined by imagining a wooden ladder with an important difference. It is that the ladder is coiled in a spiral.
What connects the two sides of the spiral tape, or the steps of that "ladder", are actually organized hydrogen bonds, but through quantum tunneling, hydrogen atoms on both sides of the tape can exchange places, causing a genetic mutation that may cause a change in the characteristics of the organism, according to a report. Scientific published by "Illuminations" in 2017, therefore; Atoms play a role in determining human hereditary traits, which is also the case with enzymes, which are essential in all vital processes of living bodies, humans, plants, etc.; It is possible to understand the activity of electrons and their control in these vital processes affecting life, only through the aforementioned quantum tunneling theory.
And not far from quantum biology, quantum computers come, which are the most superior in human history, and need more years to develop, but they also work through quantum physics applications, "and the existing ones can perform computational, analytical and data processing operations, faster than billions." times than regular computers, especially since they rely on overlay in storing and processing data, and overlay means, simply: dealing with data, by processing it in its different states together, and at one go. Quantum "QBITS" allows a quantum computer to perform a million calculations at the same time, while a home office computer can only do one.
A quantum computer is not like other computers and is millions of times more capable
Quantum physics has played a major role in understanding the possibilities of the shape of matter and the ability to direct and use it, and its employment in energy and other fields, as happened in the development of techniques for using lasers, for example. It also works on the most important questions in cosmology, including determining the size of the universe, and the concepts of photons, which are elementary particles of light. , which enters into the structure of the universe, and it is amazing that it has a role in the human senses, such as sight and smell, for example, and it is subject to a set of possibilities, which makes the reality on which we see the universe an inaccurate matter; Quantum physics also intervenes in the issue of consciousness, and indicates that the world is a probabilistic world, which may be in many different states at the same time, according to the fact that photons take on two mutually exclusive states at the same time, just as if they are alive and dead at the same moment.
Therefore; The world is far from the reality we live in, amazing to the point of doubting human consciousness. Is this awareness the result of quantum, or the quantum (photon) as a result of it?! These contradictions and speculations raised by quantum physics prompted one of the most important pioneers of this theory, Niels Bohr, to say: "Anyone who is not shocked by the quantum theory has not yet understood it."
