Here are 5 tools in our lives governed by quantum physics laws sciences

UNESCO announced in 2025 an international science and technology in 2025 to celebrate a science that changed our understanding of the universe and opening new horizons for technological development. It is quantum physics, micro -body physics like atoms and particles, a world parallel to our world governed by strange and radically different laws from those that control the big bodies around us.

The quantitative physics that arose at the beginning of the last century is no longer just a scientific theory, but also the basis of the most important applications that we use in our daily life. But in order to understand the importance of the quantitative physics and the revolution that it brought about in the techniques we use today, it is necessary to first understand the most important laws on which this science and the circumstances that led to its origins are based.

In the footsteps of Plank

Dr. Adel Trabelsi, a quantitative professor of physics at the College of Science in Tunisia, says in a special dialogue with Al -Jazeera Net, that quantum physics originated at the beginning of the 20th century. During this period, some issues, such as the exchange of energy between bodies, seemed to be interpreted by classical physics. It was necessary to search for innovative solutions outside the traditional scientific theories that senior scientists have developed in the history of science such as Newton, Galilee, Maxwal and others, and this was not easy.

Trabelsi adds that the German physicist Max Planck was the first to realize that the energy of light waves was formed, unlike the traditional perception, from micro -package of unconnected energy he called “Quanta”.

This idea is the basis on which new physics was built. After that, many scientists developed a theory, the first of which was the famous physicist Albert Einstein, who considered that the energy packages that Black talked about is in fact not the amount of energy but rather the Voton particles. Then a group of scientists, including the Austrian Arwin Schroenger, the German Werner Heisenberg and the English Paul Dirac who made fundamental contributions to lay the foundations of quantum physics.

Strange properties

This physics is characterized by laws or properties that make micro -particles such as photon and electron, act amazingly. According to Trabelsi, a particle in this microscopic world can be in two contradictory cases, such as being still and moving at the same time or rotating from right to north and from north to right at the same time.

Two elements can also be closely interconnected while the universe is separated by them. If one of them is exposed to an external influence, the second responds to this effect in the same way as the first method, even if they are separated by a great distance, as Dr. Siham Al -Jaziri, a quantitative professor of physics at the College of Science in Tunisia in a dialogue with Al -Jazeera Net.

According to the principles of quantum physics, physical particles, such as electrons, show wavelengths in addition to their properties as a physical particle, which means that they can act as a wave, overlap and affect each other as the waves do.

It also happens that Jexman interacts in a way that makes the condition of one of them linked to the case of the other, and they are in a state of tangle, regardless of the distance between them. And if the condition of one of the particles is measured, the other particle is affected immediately, which challenges our traditional understanding of time and space.

These particles can also exceed energy barriers that appear impossible, while scientists call it “tunnel effect”, which explains phenomena such as radiological activity.

Micro -electronics and computers

These strange features were behind many basic technical applications in our lives today, such as computers and accurate electronics that are based on the transistor.

The transistor is the first quantitative applied device that uses quantitative properties for electrons within the material, says Dr. Siham Al -Jaziri, a quantitative professor of physics at the College of Science in Tunisia.

The transistor depends on the principles of quantum mechanics, specifically on the movement of electrons within the semi -connected materials according to the “tunnel effect” feature that allows the electron to enter and exit without adjusting the set of atoms that make up the transistor.

These transistors control the flow of electrical current, allowing data to be represented and processed. Without transistors, it was not possible for all electronic devices around us such as phones, TVs and computers to exist.

Laser rays

The laser is an artificial light beam developed by physicists through the application of quantum laws, and depends on the principle of emission that stimulates radiation, which is a quantitative phenomenon during which photons with specific energy stimulate atoms to launch other photons with the same energy, phase and direction, which results in a consistent and high -density light.

Laser applications include wide areas, from reading optical discs and communications via optical fibers to accurate surgery to advanced scientific research.

Dr. Al -Jaziri says that the laser, with the Trotsor, represents the most prominent foundations of the first quantity that started since the middle of the last century.

MRI

At very low temperatures, electrons do not act as separate particles within the network of atoms, but rather turn into giant waves according to the superior conductivity law. Thanks to this quantum phenomenon, scientists can create large magnetic fields that constitute the basis of MRI technique.

These waves vibrate the hydrogen nuclei (protons) found in all living tissues. Since each member contains a certain amount of hydrogen and acquires its own wave hesitation (energy zealine), a three -dimensional image of the internal tissues of the body can be produced.

GPS systems

The first global positioning system was launched in 1978, and today these systems that depend on quantum mechanics are widely used in smartphones, car navigation systems, military equipment and many other applications.

GPS, such as the GPS system, according to Al -Jaziri, using the atomic watches included in the satellites that revolve around the Earth. Unlike the pendulum watch that depends on the movement of the pendulum and is affected by many variables, the accuracy of the atomic clock depends on the atoms, the element of seesium known for the stability of its frequency.

Quantum computing will lead the revolution the second quantity

Quantum computing is an emerging technique that uses the principles of quantum mechanics to process information in new ways. Unlike traditional computers, which use bits as the smallest information unit, quantum computers use quantum bits.

Dr. Adel Al -Trabelsi explains the difference between quantum and traditional computing by saying, “On the classic computer, operations that are performed with petals can have two values ​​or two cases only zero or one. As for the quantum computer, the bits can be at the same time at the same time (overcoming cases), and these units are called quantum petals or kubat. Close to each other thanks to the tangle feature. “

The spokesman added that the implementation of these two principles increases the possible possibilities, as if we were making several parallel accounts at the same time. This allows the quantum computer to make complex accounts much faster than the current computers, as the operations that take the classic computing hundreds of years to solve, may only take a few seconds in quantum computing.

A great competition is currently taking place between researchers to develop quantum computing and its applications have already begun, according to Dr. Siham Al -Jaziri, adding that she is in the process of creating a second quantitative revolution.

Since Max Planck laid the foundation stone more than a century ago, quantitative physics has turned from a mysterious theory to technological power that changes our lives. Whether you are browsing your phone, heating your food in the microwave, or following your site on the map, the quantity is around you. While we celebrate this flag in 2025, it seems that we are on the verge of a new technological boom that will make the impossible reality, all thanks to the world of small particles governed by strange quantum physics laws.
