Quantum Mechanics is one of the greatest enigmas there is. It is really complicated and difficult to understand. There are professional individuals still studying and trying to figure out everything there is to know about this subject. Quantum Mechanics consists of many interesting facts people do not think about on a regular basis, yet it is part of their everyday life. Quantum Mechanics is such a big mystery, scientist are still doing research and learning from it. It findings may revealed to have bizarre explanations about the physical world. According to Shurkin, Scientists believe that all primary laws of physics applied to everything in nature. However, they started to research and study the world of the ultra small which included light, waves, atoms, electrons, etc. Quantum mechanics is the branch of physics that deals with matter on the atomic and subatomic scale. “Quantum mechanics is the body of scientific laws that describe the wacky behavior of photons, electrons and the other particles that make up the universe.”(Coolman) It is the branch of physics that oversees the formation of infinitesimal pieces of matter. It involves mathematical interpretation of the evolution and interactions between particles. “It attempts to describe and account for the properties of molecules and atoms and their constituents such as electrons, protons, neutrons, and other more esoteric particles like quarks and gluons.” (Squires) According to Squired, the idea of Quantum Mechanics was first instituted by Max Planck, a german physicist. Nevertheless, the creation of Quantum Mechanics can not be credit to one scientist because multiple scientist have participated in this subject throughout the year. “The clue that triggered the quantum revolution came not from studies of matter but from a problem in radiation. The specific challenge was to understand the spectrum of light emitted by hot bodies.” (coolman) As stated by Squires, Max Planck guesstimated that the full energy from a vibrating system can not be constantly change. Therefore, the energy needs to jump in quanta from one value to another. Later, many scientists modified the theory, adding their own hypotheses and ideas, some of these people were Albert Einstein, Niels Bohr, Erwin Schrödinger, Paul A.M. Dirac, etc.These scientists contributed to a theory of three revolutionary principles that are proven right by experimental authentications. One of this principles is quantized properties. “Certain properties, such as position, speed and color, can sometimes only occur in specific, set amounts, much like a dial that “clicks” from number to number. This challenged a fundamental assumption of classical mechanics, which said that such properties should exist on a smooth, continuous spectrum.” (Coolman) When trying to elucidate the issue of colors released in the spectrum Max Planck noticed it implied to a mixture of certain colors. By any means, Colors were quantized. “This was unexpected because light was understood to act as a wave, meaning that values of color should be a continuous spectrum.” (Coolman) According to Squires, Planck demonstrated the calculated energy spectrum and then approved with study over the whole wavelength range. “the energy E of the quantum is related to the frequency ? by E = h?. The quantity h, now known as Planck’s constant, is a universal constant with the approximate value of 6.62607 × 10?34 joule?second.” (The Developments) According to Coolman, Planck’s equation carried a number that would actually become remarkably essential to future instigation of Quantum Mechanics. Particles of light was also one of the three principles that helped the foundation of Quantum Mechanics. As stated in Squires, in 1905 Albert Einstein gave his examination to Planck’s mathematics,he suggested that electromagnetic radiation itself is consisting of quanta. “Einstein supported his photon hypothesis with an analysis of the photoelectric effect, a process, discovered by Hertz in 1887, in which electrons are ejected from a metallic surface illuminated by light.” (The Developments) As claimed by livescience, Einstein proposed insights on the performance of nine varying phenomena. “It explained how certain colors of light could eject electrons off metal surfaces, a phenomenon known as the photoelectric effect.” (Coolman) Later, Einstein’s hypothesis was confirmed to be true. Particles of light were striking with particles of matter. Light could either act as a particle or a wave, positioning light’s wave-particle duality in the fundamentals of Quantum Mechanics.The third principle was waves of matter, basically it suggested that matter could behave as a wave. It is affirmed by livescience that this brought approximately 30 years of investigation debating whether matter could exists as particles. “The demonstration of light’s wave-particle duality made scientists question whether matter was limited to acting only as particles.” (Coolman) According to Shurkin, in many experiments, light behaves more like a wave than a particle. “This wave nature produces some interesting effects. For example, if an electron traveling around a nucleus behaves like a wave, then its position at any one time becomes fuzzy. Instead of being in a concrete point, the electron is smeared out in space.” (Shurkin) The fact that waves acts like matter and waves at times is well known as the principle of duality as stated in Quantum.According to Squires, in 1926, an austrian physicists named Erwin Schrodinger established a mathematical wave mechanics, it basically showed how to write an equation for the wave function for any physical system. “Schrödinger’s equation, the most convenient form of a more general theory called quantum mechanics to which the German physicists Werner Heisenberg and Max Born also contributed, was brilliantly successful.” (Squires) This equation allowed non complex technique for more complicated systems. “The eigenvalues of the wave equation were shown to be equal to the energy levels of the quantum mechanical system, and the best test of the equation was when it was used to solve for the energy levels of the Hydrogen atom, and the energy levels were found to be in accord with Rydberg Law.” (PhysLink.com) The solution to his equation is the wave that explains the quantum features of a system. “It is used in physics and most of chemistry to deal with problems about the atomic structure of matter. It is an extremely powerful mathematical tool and the whole basis of wave mechanics.” (PhysLink.com) Quantum Mechanics has taken mathematical inspirational of physical laws beyond calculus and other advanced functions. “The mathematical setting for quantum mechanics is an inner-product space of square-integrable wave functions with a finite-dimensional space tacked on for spin degrees of freedom.” (Quantum) The development of Quantum Mechanics had a huge impact on the whole world. It change many scientist point of view. Many other things were discovered in the process of the foundation of Quantum Mechanics, and due to this it has replaced other systems. “Quantum Mechanics also replaced classical mechanics as the method by which to describe interactions between subatomic particles. Quantum mechanics replaced electron “orbitals” of classical atomic models with allowable values for angular momentum (angular velocity multiplied by mass) and depicted electron position in terms of probability “clouds” and regions”. (Chalifour) Quantum Mechanics has had an impact on technological advances as well that makes present life possible. “Without quantum mechanics there would be no transistor, and hence no personal computer; no laser, and hence no Blu-ray players.” (Chalifour) Today, Quantum Mechanics is used to manufactured atomic clocks, they are capable of using the principles of quantum theory to calculate time. “They monitor the specific radiation frequency needed to make electrons jump between energy levels.” (Matson)Quantum Mechanics is one of the greatest things men have created. It is very important for the science world. With Quantum Mechanics scientists were able to find the answers for many unanswered questions. “Quantum mechanics has explained the structure of the atom and the structure of the nucleus without knowing the structure of the atom, most of the physics and chemistry that we know today wouldn’t have been possible.” (Society) According to Invigorate, Quantum Mechanics also help form the existence of antimatter, and it explains radioactivity. Quantum mechanics can be a rare topic and difficult to understand. Its result can appeared really extraordinary and unbelievable too many people. Quantum Mechanics opened the doors to many physicist to keep exploring the world in another level. It is difficult to understand because it involves many properties and laws.Quantum Mechanics is a procedure of scrutinizing the natural world built on the concept of waves of energy. Moreover, It involves requires some properties usually corresponding with matter. It has made many changes for example the advances in cosmological theories. This concept is so unique sometimes it can be misinterpreted to make wrong predictions. However, the verity that this topic has not been perfectly analyzed brings countless questions on what else is out there in the nonphysical world.
