What is Quantum Physics for Beginners and 5 Uses in Daily life?

When you look at the world around you, the question that arises in the mind is what it’s made of? We and all the things around us are made up of the stuff which is called the matter.

Scientists discovered the building blocks of matter i.e., an atom. And Quantum Physics explains how the world’s building blocks (atoms and electrons) are put together.

The theories of Quantum Physics developed by physicists are very complex. Even brilliant scientist finds it difficult to understand. Here we are focusing on a few basic concepts of quantum physics.

Quantum Physics definition:

Quantum physics is the study of the behavior of matter and energy at the molecular, atomic, nuclear, and smaller microscopic levels. It allows the calculation of the properties and behavior of physical systems around us. It is also called Quantum Mechanics.

In other words, Quantum physics is the physics that explains how particles make matter and the force with which they interact. It supervises the way the universe behaves on the scale of atoms, electrons, and photons.

What Does Quantum Mean?

“Quantum” comes from the Latin meaning “How Much.” It refers to the minimum amount of any physical entity involved in an interaction or evolvement.

What is Quantum Physics?

In 1900, the German physicist Max Planck (1858–1947) described the ultraviolet catastrophe by proposing that the energy of electromagnetic waves is quantized rather than continuous flow. Quantum physics theory clarifies the physical properties of nature at the scale of atoms and subatomic particles.

According to Planck’s quantum theory, different atoms and molecules can emit energy in discrete quantities only.

The smallest amount of energy that can be absorbed in the form of electromagnetic radiation is known as quantum.

The energy of the radiation absorbed is directly corresponding to the frequency of the radiation. It is physics that explains how everything works together with atoms, chemistry, and biology science.

This Quantum physics is a fundamental theory of quantum mechanics. In our daily lives, we used computers, mobile, laser machines, medical machines, etc. these electrical appliances use quantum mechanics.

Why has energy come in discrete packets only?

Quantum Mechanics was still just a mathematical explanation. No one could explain why energy came in discrete packets.

In 1913, the Danish physicist Neil Bohr proposed a new model for the structure of the atom. He said that those electrons need to be set in a specific path. These paths are known as planets orbits around the Sun called “orbitals.” Each orbital has its own energy level.

When an electron absorbs energy, it moves from one orbital to the next orbital. When an electron falls from one orbital to the next orbital it emits energy.

The amount of energy emitted is exactly the energy difference between the two orbitals. Because of this energy is divided into a discrete value called “quanta”.

As per Planck Theory, the quantized energy was electromagnetic radiation emitting from electrons in hot objects. As per Einstein’s theory photons transfers their energy to electrons in the metal.

If the photon energy was high enough, the electron would leave its orbital. So, Bohr’s electron orbitals provided a theoretical explanation for quantum mechanics.

Uses of quantum physics in daily life?

Uses of quantum physics

Electronic Appliances

In all electrical appliances, we notice the glow of the red light which is because of quantum physics.


In our cameras, the lens catches the photons and focuses them on the sensor which in turn throughs out electrons.


The basic element inside a computer is known as a transistor which utilizes the basic electronic properties of Silicon (semiconductor. As we know electrons in semiconductors behave like a wave, thus all computers use quantum mechanics.

Light Emitting Diodes (LEDs)

Light Emitting Diode is a light source that is based on two layers of semiconductors. When these two layers meet each other, it releases energy in the form of light energy. Thus, we are using the quantum technique here.

Light Bulb

When the current passes through a thin wire which is tightly coiled inside the glass bulb it makes the wire hot and the bulb glows. This work is based on quantum mechanics.

Quantum physics reality is an illusion

In 1980 the British physicist Roger Penrose suggested that consciousness can affect quantum mechanics, he said, perhaps quantum physics is involved in consciousness. He explained that our incompatible mental states are no quirk of perception, but a real quantum effect. He first proposed that quantum affects Human cognition in his 1989 book called “The emperor’s new mind”.

Quantum Physics revolutionary:

It is the study of matter and energy. Atoms form light particles, we cannot see them, but we can understand through experiments and research. Is the human body made up of Quantum Physics Science? Are we made up of particles, matter, or energy?

The answer is Yes. Our philosopher said that our soul is separate from energy and the universe is energy. An atom is made up of indivisible force which emits electrical energy. But when we go in-depth, we can understand that matter is the only energy.

  • Is Quantum Physics connecting Spirituality and Modern Science?

There was no harmony between science and spirituality. It is like science on one side and spirituality on another side.

But these days many researchers are looking at a common thread that ties the two disciplines together. It will help to find commonalities that would further enrich human knowledge.

  • How quantum physics science works behind mindful mediation and Yoga? 

Mindful meditation helps us to relax, calm, build our internal spiritual energy to lead a balanced and happy life. It is like the transmission of spiritual energy (Pranahuti) from the heart to all over the body in a faster way.

When we practice meditation daily with energy transmission it reflects our inner soul. This Pranahuti purifies our internal energy by which our consciousness extends more deeply. Our inner vibration expands with consciousness and the superconscious mind increases.

Our conscious minds experience sensations around us like the smell of flowers or red color flowers. With this, we know this is just a visualization. Sensations are called as “Qualia” product of consciousness.

Our mind affects the outcomes around us. It does not mean “what is exactly real?” but it views the chances of quantum science.

When we improve our connection between energy and matter, we can gain a quality life. The energy contains all the mechanism of our body and matter contains our mind and soul.

Quantum physics is spiritual origin with a scientific approach. It is experimental which leads the human being connected with the universe.
