Physics opens a Pandora’s Box every time physicists take a step to know it better. Quantum physics, also known as quantum mechanics is the physics of and related to the tiny, such as atoms and subatomic particles. The first quantum theory was discovered by Max Karl Ernst Ludwig Planck or Max Planck in a late 19^{th} century and won a noble prize in 1918 for the discovery and of quantum physics. Max Plank referred to the quantum theory as energy quantum, in these days; there are many principles of quantum theory but only three revolutionary principles. Quantized properties, particles of light and wares of matter, so, what are these?

Quantized properties

Max plank chased the explanation of the distribution of colors emitted over the spectrum in the red-hot and white-hot object’s glow, such as the filaments of the light bulb. In the 19s century, he found out making his equation’s physical sense, which he has obtained to describe this distribution that combinations of certain colors were emitting, specifically those which were whole number multiplying of some base values. Mysteriously, colors were quantized! No one expecting it because the light was supposed to act like Waves which means the colors values should be a continues spectrum what was forbidding atoms from producing the colors between these whole- number multiplies?

It was so strange that Planck considered quantization as nothing more than a trick of mathematics “If a revolution accrued in physic in 1900. Nobody seemed to notice it. Planck was no exception” Hedge Krogh worth in the equation of Max pluck, the reluctant revolutionary. The equation of Max Planck had a number that becomes very important for the future development of quantum mechanics today; it’s now called *Planks Constant*.

Quantization also helped to explain several mysteries of physic. Even Albert Einstein used the theory of Planck of the equation in 1907 to describe why the temperature of solid changes by different amounts if you put the same amount of heat into the changing the starting temperature. Since the early 18s, the spectroscopy’s science showed different elements emit and absorb certain colors of light known as *spectral lines*.

Although spectroscopy was a reliable method for determining the elements contained in objects, for example, distant stars. Scientists were replaced as they were unable to understand why every element gave off those specific lines in the first place! Johannes Rydberg derived an equation showing the spectral lines are emitted by hydrogen and nobody was able to explain why the equation worked.

Later the, it changed in 1913, when Niels Behr applied the quantization’s theory of Max Planck to the planetary model of Ernest Rutherford which Earnest created in 1911, proving electrons orbit the nucleus similarly as planets orbit the sun. Bohr also said that electrons were restricted to special orbits around the nucleus of an atom. They could jump between the special orbits and the energy produced by the jumps caused specific colors of light that are observed as the spectral lines, this is how the quantized properties became the founding principle of quantum mechanics from just a mathematics trick.

Particles of Light

*Concerning a heuristic point of view toward the emission a transformation of light* this paper was published by Albert Einstein in 1905. In the paper, Einstein referred that light travels not as eve but as some manner of *energy quanta*. He proposed that this packet of energy could be absorbed or generated only as a whole, precisely when an atom jumps between the quantized vibration rates. This can be also applied, has been shown some years later when an electron jumps between the quantized orbits. The energy quanta of Einstein contained the energy difference of the jumps under this model and he divides by the constant of Planck, the energy difference determined the color of light carried by those quanta.

Albert Einstein proposed insights the nine different phenomena’s behavior with this new way to visualized light, including Planck’s those specific colors which he described emitted from a filament of the light bulb. It also described how certain colors of light could emit electrons off the metal surface, which is a phenomenon, *The Photoelectric Effect*.

‘The photoelectric: rehabilitating the story for the physics classroom,’ Said Stephen Klassen, an associate professor of physics at the University of Winnipeg worth in this 2008s paper, however, Einstein wasn’t completely justified in taking this leap. In the statement, Klassen stated that the energy quanta of Einstein aren’t compulsory for explaining the nine phenomena certain mathematical treatments of light as just a wave is capable to explain the planks specific colors that emitted from the light bulb filament and the photoelectric effect

Approximately after almost 20 years of the Einstein’s paper them *photon* become popular describing the energy quanta, it happened because of the Arthur Compton’s work of 1923, showing that light tossed by an electron beam changed in color. And this proved that the light particles’ *photons* were actually colliding with the electrons, the particles of matter confirming the hypothesis of Einstein. Now it proves that light behaves both as particles and a wave placing the *wave particles duality* of light the creation of quantum mechanics.

The Wave of Light

Everyone was pretty sure that all matters exist in the forms of particles also the evidence was forming slowly after the discovery of the electron in 1896. But the demonstration of wave particles duality of light forced to acting only as particles. The wave-particle duality can ring true also for matters. Lous de Broglie was the first scientist making substantial headway with this reasoning in 1924, using the equations of Theory of Relativity.

He showed that particles can show particles like characteristics later, two scientists applied de Broglie’s reasoning using separate lines of mathematical thinking in 1925, for explaining how electrons whirled around in atoms, it’s a phenomenon that was unexplainable using the classical mechanic’s equations. A German physicist Werner Heisenberg with Max Born and Pascual Jordan accomplished it developing *matrix mechanics.* Erwin Schrödinger an Austrian physicist built a close hypothesis known as *wave mechanics*. Though Wolfgang Pauli, a Swiss physicist sent an unpublished result to Jordan which showed that matrix mechanics was more complete, still in 1926, Erwin showed that these two approaches were equal.

The model of Erwin and Heisenberg, in which electrons act like wave also sometimes referred to as *cloud* around the nucleus of the atom replaced the Rutherford-Bohr model. The new model’s stipulation was that the wave’s end that forms an electron must meet.

Melvin Hanna wrote in the *Quantum mechanics in chemistry 3 ^{rd} edition*, “The imposition of the boundary conditions has restricted the energy to discrete values. The result of the stipulation is that only whole numbers of crests and troughs are allowed, which describes why some properties are quantized. In The Model of Heisenberg and Erwin of the Atoms, Electrons obey a “wave function” and occupy orbitals rather than orbits unlike the round orbits of the Rutherford-Bohr model.

Atomic orbitals have variations in shapes ranging from spheres to dumbbells of daisies. Later, Fritz London and Welter Hailer developed the wave mechanics in 1927, to exam plain how atomic orbitals could combine to form molecular orbital’s effectively showing why atoms bond to each other to form molecules. It was one more problem that had been unsolvable using the classical mechanic’s mathematics. Later, these insights rose in the fields of quantum chemistry.

This is how quantum physics contributed to helping us understand such small but important things in physics. And scientists say that it’ll help more but what will be its future well, we know quantum mechanics as a research disciplined ended in the sixties with the arrival quantum field theory, the Rigorous Formalization of mixed states of Von Neumann and the Bell’s theorems discovered by John Stewart Bell, with the first playing largest role and together these represent the traditions quantum mechanics extension to a lot of things, such as the prediction that the extinct of particles spine from first principles, establish the quantum mechanics cannot be described with the help of classical theory except if the information is allowed to travel faster than light.

Also, include the special reality that quantum field theory accomplishes beautifully etc. So the actual future of quantum mechanics is what remains now are not questions for quantum mechanics but questions about the application of quantum mechanics.
