Quantum mechanics is a form of physics that is used to study very tiny objects like atoms. Many people have heard of quantum mechanics before whether it was from a book or a television show. Automatically people think “nerd” or “geek” which is pretty much correct, but those people themselves have no idea how quantum mechanics improved their lives or even how it works. It may sound difficult, but it is really not that hard to understand.
So now it is time for the all import question that everyone wants to know. What is it? Quantum mechanics is not the study of tiny things like cells or microbes. It is the study of even tinier things called particles. The main reason why we have quantum mechanics is because it replaces classical physics for describing events and actions that occur with particles and other objects that are on a very small scale (Tavolacci). We use the quantum theory because Newton’s laws can not accurately explain what happens to objects on a smaller scale and so quantum physics has helped scientists understand a little more about the particles that make up the world (Tavolacci). The quantum theory states that all matter, energy, and radiation are made up of small bundles called quan (or in plural form quanta) hence the name “quantum” mechanics (Tavolacci). The theory also states that electrons move in a defined wave instead of just flying around the nucleus of an atom because if they floated around aimlessly, then the electrons would collide with the nucleus in a fraction of a second and all matter that we know would cease to exist (McCoy). The electrons stay in certain waves based on their energy level. It is much easier to think of this whole process of acting like a solar system. All of the electrons move around...

...here the electrons move and go. The photons from the light transport energy and hit the electron, which transfers energy to the electron but slows down the photon. At last, in the 1920’s scientists came up with the wave-particle duality. The wave-particle duality stated that light had both properties of a wave and properties of a particle at the same time (Tavolacci).
Quantum mechanics has been around for at least a century and for about half of those years it has been widely rejected. When scientist finally saw its potential, they opened up to the idea and started creating many new experiments and finding out the great answers to the biggest questions in life. Scientists will continue to make amazing advancements in quantum mechanics and may be able to one day figure out a way to improve our lives with some of the greatest technology that mankind has ever seen.
Kuhn’s theory of paradigm shift. Mr. Bawazer offers a strong case. As an example from Mr. Kuhn’s theory we can understand how the different dog breeds evolved from the wolf. Depending on what type of breed you want from a hunting dog to a family dog breed, you can alter the DNA by letting the alpha dog to continue to breed or not. Next, we can realized that everything in this planet contains molecules or genes that can be altered. We also recognize that paradigm science and paradigm shift is a circular state not a steady line. This means that we have to adjust to what is going on the present time and expand from it, but always remember how it was done in the past. Thomas Edison well said “I have not failed. I’ve just found 10,000 ways that won’t work.” The only way to change science is to continue to try without being afraid of failing. If different engineers and industries unites forces to promote the use of natural resources rather than inventing new ones and also with the help of the government of going “green” will definitely help the environment to prevent
Alice finds herself in a place named Quantumland. In Quantumland, each attraction demonstrates something different used in science. To be able to understand Quantum Land, Alice is told she must first has to travel to the Heisenberg Bank. She began asking questions, when a guard tells Alice she can’t skip in line. She quickly becomes confused because she is not standing in a line. She then saw electrons begin to morph together and others vanish. The Bank Manager begins to explain to Alice that the bank is in charge of distribution of energy loans to all virtual particles. In order for a particle to exist it must have a certain minimum energy, called its rest mass energy (Gilmore 14). The electrons are about to get loans of energy from the Heisenberg Bank which allows them to exist for
The novel, Alice and Quantum Land, by Robert Gilmore is an adventure in the Quantum universe. Alice, a normal teenage girl, goes through quantum land and understands what quantum is and how it works. The quantum world is a difficult one to understand, as its nature is one of complex states of being, natures, principles, notions, and the like. When these principles or concepts are compared with the macro world, one can find great similarities and even greater dissimilarities between the world wherein electrons rule, and the world wherein human beings live. In Alice in Quantumland, author Robert Gilmore converts the original tale of Alice in Wonderland from a world of anthropomorphic creatures into the minute world of quantum mechanics, and attempts to ease the reader into this confusing world through a series of analogies (which comprise an allegory) about the principles of quantum mechanics. Through Alice’s adventure she comes across some ideas or features that contradict real world ideas. These ideas are the following: Electrons have no distinguishing spin, the Pauli Exclusion Principle, Superposition, Heisenberg Uncertainty Principle, and Interference and Wave Particle Duality.
First, special relativity describes the laws of motion of an object which moves at high speed. Meanwhile it offered the mass-energy relation which is E=mc^2 (E=energy m=mass c=speed of light). Although Einstein didn’t believe in quantum mechanics2, his mass-energy relation still helped in the establishment of it. Also this relation built the mathematical model ...
The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs.
This Essay is meant to shed light on a complex subject, quantum entanglement. Now, quantum entanglement is a part of much more complex subjects, such as classical mechanics, quantum theory, and quantum mechanics; these subjects will not be covered. The idea of quantum entanglement will be explained: What it is and when does it happen. After a little understanding of Entanglement, a discussion will follow on what it means for us from a technological standpoint and what can we accomplish in the near future. Pushing that idea further into the future looking at bigger possibilities in transportation, and what potential liabilities and moral dilemmas could ensue. It is my belief that quantum entanglement could accomplish many great things, but could
Of the many counter intuitive quirks of quantum mechanics, the strangest quirk is perhaps the notion of quantum entanglement. Very roughly, quantum entanglement a phenomenon where the state of a large system cannot be described by the state of the smaller systems that compose it. On the standard metaphysical interpretation of quantum entanglement, this is taken to show that there exists emergent properties1. If this standard interpretation is correct, it seems that physics paints a far different picture of the world then commonsense leads one to believe.
The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object. This is not the intention for the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way.
Physicists have studied light for centuries and they have always been mystified in deciphering whether it is a particle or a wave. The ancient world believed light was an extremely light and small particle that moved at incredible speeds. More recently, physicists have conducted experiments that proved that light has wave-like properties. In the early 19th century, Thomas Young, a British scientist, conducted a famous experiment in which he proved that light would interfere and diffract. A broad discussion about the nature of light emerged in the scientific world. The theories that light reflected of a surface just like a ball would, was revised because the explanation that it was a reflecting wave was a more convincing one. The fact that light would bend with a large amount of gravity cannot be revoked and this attributed light a certain amount of mass. Since waves are not supposed to have a mass, in the same way that particles are not supposed to diffract, reflect, and refract. The contemporary scientists are intended to abide in the “wave-particle theory” which combines all the facts of light and place it in a category that does not follow the duality reasoning behind the wave or particle division.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Some physical entities such as light can display some characteristics of both particles and waves. Before the early 20th century, scientists believed that light was in the form of an electromagnetic wave. It wasn’t until the 20th century onwards that scientists found that light has properties of waves and particles. Scientists discovered different properties of light through experimentation and allowed them to determine that light actually has a wave-particle duality.
...pecial relativity has caused profound changes in the way we view our universe at its most fundamental level. The theory has had an effect on many areas of science, especially physics. Even though many people did not think that special relativity was anything more than a theoretical idea, it has been tested numerous times. In every case, the predictions of special relativity are upheld. Special relativity is a cornerstone upon which modern physics has been built, and it is one of the greatest discoveries of the twentieth century.
There are still limitations in classical cryptography, it is purely mathematical and information cannot be separated from its physical representation. In Classical physics, we use binary form to store and process the data. In the 1980s, C.Bennet, P.Benioff, R.Feynman and others observed that new and very powerful ways of information processing are possible with quantum mechanical systems. This gave birth to the concept of quantum computing.
In conclusion the only way the everyday consumer could technically have a quantum computer is by owning 14,000 grams of gold. In reality, the commercial quantum computer will be a coming in a lifetime. Currently, the quantum computer can only calculate elementary math and nothing more. We could use the qubit to build softwares that could theoretically process
During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.
