Quantum Mechanics: Unraveling the Mysteries of the Microscopic World
Today, we will discuss about Quantum Mechanics, which created a sensation in the world of science. It is not as difficult as it seems.
It is a study of how small particles work. It is the branch of physics that tells us how the most fundamental bricks of this world work. Because the principles of Quantum Mechanics run the world around us.
Whether it is the battery of your smartphone, the light of the sun, or our own body, everything follows the rules of Quantum Mechanics. As soon as we step into the world of Quantum Mechanics, we face a world which is completely different from our everyday world. It is a world of very small particles, where the rules are different, and what happens is often completely different from our thinking.
Imagine a world where one thing can be present in two places at the same time. This strange world is the heart of Quantum Mechanics. Quantum Mechanics has given us revolutionary things like laser, transistor, and computer chips.

And in the future, it can pave the way for even more amazing discoveries. The story of Quantum Mechanics begins at the turn of the 20th century, when there was going to be a huge change in physics. Until then, scientists believed that energy is like a continuous flow, like the flow of water or the gust of wind.
But a great German scientist, Max Planck, challenged this thought. He presented a revolutionary idea that shook the foundation of physics. Planck was working on a problem at that time, which was called Blackbody Radiation.
This problem was failing to explain why hot things emit light in different colors. Planck took a different approach to find the solution to this problem. He believed that energy comes in small packets or bundles, which he named quanta.
This was a thought that changed the whole world. According to Planck, energy is not like the flow of water, but like a ladder. Just like you can step on a ladder while climbing a ladder, you cannot stop in the middle.
Similarly, energy can also take only certain values, which are called quanta. Planck also said that each quantum energy is multiplied by a certain number, which we today call Planck's constant. This number is a fundamental constant of quantum mechanics.
And it reflects the most fundamental rules of the world. Planck's thought was no less than a big change for physics. Before this, scientists believed that the value of energy can be anything.
But Planck showed that energy is also quantized. That is, it can only take certain values. This was a thought that laid the foundation of quantum mechanics and started a new era in the field of physics.

To understand this revolutionary thought of Planck, we will have to understand the problem with which he was struggling. Blackbody radiation and ultraviolet catastrophes. A blackbody is such a thing that absorbs all kinds of light and then removes it.
The problem was that according to the rules of ancient physics, a blackbody should emit a lot of energy, especially in the form of ultraviolet light. This was called an ultraviolet catastrophe. This was not possible because we know that nothing can remove so much energy.
Planck's quantum theory gives the solution to this problem. Planck showed through his quantum theory that the energy emitted by the blackbody is not continuous, but it comes out in the form of small packets or quanta. This meant that the energy of the quanta emitted in the form of ultraviolet light is very high and that is why their excitation is less.
This principle of Planck not only solved the problem of the ultraviolet catastrophe, but also started a new era in the world of physics. This was the first time when someone said that energy is not continuous, but it is quantized. This revolutionary thought of Planck laid the foundations of modern physics and paved the way for Einstein, Bohr and other scientists.
Max Planck's quantum theory had opened a new chapter in the world of physics, but even then the quantum could not be fully understood. Planck had said that energy is quantized, but it was not clear what it really meant. Here comes another great scientist of physics, Albert Einstein.
Einstein advanced Planck's work and showed that the use of quantum theory can also be used to explain the nature of light. Einstein published an important research paper in 1905, in which he explained the photoelectric effect. This effect was a puzzle for scientists at that time.
In the photoelectric effect, when light hits a metal, electrons come out of it. The problem was that the old laws of physics were not able to explain this effect. According to them, the number of electrons emitted by increasing the intensity of light should increase.
But in experiments, something else was being seen. The energy of the electrons emitted by increasing the intensity of light increased, not their number. To solve this puzzle, Einstein used Planck's quantum theory.
He said that light comes in small packets of energy or in the form of quanta, which we call photons today. The explanation of Einstein's photoelectric effect strengthened the quantum theory. Now it was clear that light behaves not only like waves but also like particles.
This double-dealing forced scientists to think more. At the same time, another great scientist, Niels Bohr, was busy understanding the structure of the universe. Until then, scientists knew that the universe is a very small ship, with electrons circling around it.
But according to the old laws of physics, the electrons should have fallen into the ship. Bohr used the quantum theory to solve this problem. He presented his quantum model of the universe in 1913.
Bohr said in his model that electrons can only circulate in certain areas, which are called energy levels. Every energy level has a fixed energy, and electrons can go from one energy level to another energy level only when they absorb or release energy in a certain amount. Bohr called this process a quantum leap.
He said that electrons do not go from one energy level to another energy level slowly, but they suddenly jump from one level to another. Bohr's model was successful in explaining the results of the available experiments at that time, and it strengthened the quantum theory even more. This is an important concept of quantum mechanics, which tells how energy is transferred in an atom.
Great scientists like Planck, Einstein, and Bohr, had put the foundation of quantum mechanics together. But as scientists wanted to know more about this new world, they realized that this world is as wonderful as it is strange and poor. The rules of the quantum world are completely different from the rules of our everyday world.
Here, things can be in two different states at the same time, atoms can be connected to each other without any connection, and uncertainty is the only certainty. This may sound strange to you, but it is true. Quantum mechanics tells us that at a very subtle level, the world works in a completely different way from our experience.
Let's try to understand some of the strange and poor rules of this wonderful world. One of the most important rules of the quantum world is the principle of uncertainty. This principle was given by German scientist Werner Heisenberg in 1927.
This principle says that we cannot know the position and speed of something with complete accuracy. If we measure the position of something very accurately, we get less information about its speed. And if we measure its speed very accurately, we get less information about its position.
This is not a limitation of measurement, but it is a fundamental rule of nature. In the quantum world, uncertainty is the only certainty. Quantum superposition is another strange and poor rule of the world.
This rule says that one thing can be in two or more than two states at the same time. For example, one electron can be in two different energy levels at the same time. This is possible until we try to measure its energy.
As soon as we measure its energy, the electron comes in one of the two states. It is like a coin that can be head or tail at the same time. But when we see it, it is either head or tail.
Quantum is another wonderful and mysterious rule of the world. Quantum confusion. This rule says that no matter how far two particles are from each other, they are connected in a strange way.
If we measure the state of one of these particles, the state of the other particle is immediately known. No matter how far that particle is. This is such a mysterious connection, which is impossible to explain by the old rules of physics.
Einstein himself called this incident a distant phenomenon, because he found this thought very strange. Friends, so far we have understood the basic principles of quantum mechanics and seen how strange and mysterious this world is. But do you know how useful this strange and mysterious world is for us? Quantum mechanics has helped us develop such technologies that we could not even imagine before.
These technologies are changing our world and will bring even greater changes in the future. Quantum technology, which we can also call the second quantum revolution, is using the principles of quantum mechanics to create new and powerful technologies. This revolution is already affecting many aspects of our lives and its impact will increase in the future.
So let's take a step into the world of quantum technology in this content and see how quantum mechanics is shaping our future. The best example of quantum technology is laser. Laser is a device that concentrates light in a thin beam and produces very bright rays.
The invention of laser was based on the principles of quantum mechanics and today it is used in hospitals, communications, factories and entertainment. In addition to laser, quantum mechanics has also given us important things like transistor, diode and computer chips. All this is the basis of our electronic devices today.
But the story of quantum technology does not end here. Scientists are now using quantum mechanics to create even more powerful computers, which are called quantum computers. Quantum computers will be much faster than today's computers and will be able to solve complex problems, which will take today's computers thousands of years to solve.
The use of quantum technology is not limited to computers and electronics. It is being used in hospitals, communications, energy and many other areas to bring about big changes. Quantum technology is being used in hospitals to develop new medicines and treatments, to quickly diagnose diseases and to improve operations.
In the field of communication, the quantum transmission network promises to create such communication systems that cannot be hacked and which can send information faster than the speed of light. In the field of energy, quantum solar cells and quantum batteries promise to make more efficient and durable energy sources. In addition to these, quantum technology is also being used in areas such as material science, weather forecasting and financial modeling.
