Quantum theory, which has been discovered for more than 100 years, changed the game rule. It seems to be a disaster and also a godsend. In this article, I would like to introduce this rarely-known game changer which changed the classical to the modern, analog to digital, and certainty to uncertainty. Few people notice that quantum appear in everywhere, not only about science, but also highly related to technology, contributing our modern world. Let's have a look into the amazing quantum world.
At the moment that Max Plank discovered the light-quanta in 1900, the modern quantum physics had been started. Several years later, Niels Bohr discovered the quantum-leap and it brought out the quantum theory. The quantum theory, creates the totally mystery world, redefining our understanding of the reality. It seems to be a disaster that the classical physics may be totally wrong. No one can predict where a quantum will go before you take a measurement under the principle of uncertainty. This leads to a contrast to what we believed in classical physics. (Davies, 1982) Fortunately, this inte...
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.
The idea of parallel realities has existed within the literary circle of science fiction for many years. One of the key concepts behind alternate dimensions is that with every action and decision - whether it is consciously made or not - another alternate dimension has the opposite action or decision made, and that there are subsequent realities created in which every other option exists uniquely. Ursula LeGuin's short story "Schrödinger's Cat" is a direct manifestation of the idea of paralleled realities in that the story deals with an experiment that spawns countless paralleled realities. Merely one of the skewed realities is overseen during the course of the narration. The Schrödinger "Gedankenexperiment" ("thinking experiment" in German) is a hypothetical situation in which a cat is placed in a sealed box with a gun and a photon emitter that has a fifty percent chance of firing the gun and killing the cat, and a fifty percent chance of not firing the gun and not killing the cat(2230). The possibility for other outcomes remains ever present, although infinitesimally slim with the percentage of anything else occurring. "We cannot predict the behavior of the photon, and thus, once it has behaved, we cannot predict the state of the system it has determined. We cannot predict it! God plays dice with the world!" (2230) The three characters who appear within "Schrödinger's Cat" act as the different variables within an experiment: the control; the dependent variable; and the independent variable. Each of these characters exists and does not exist within any reality and their existence (or lack of) is dependent upon time and which timeline they are involved i...
Quantum Mechanics This chapter compares the theory of general relativity and quantum mechanics. It shows that relativity mainly concerns that microscopic world, while quantum mechanics deals with the microscopic world.
Over a 1950 summer lunch at the Los Alamos National Laboratory, the great physicist Enrico Fermi asked his colleagues an unexpected question – “Don’t you ever wonder where everybody is?” Laughter went around the table as everyone immediately knew that he was talking about extraterrestrial intelligence [1]. If life arises fairly commonly, as Fermi believed, it follows that there should be advanced civilizations with the desire to visit and colonize Earth close enough to do so. However, there is no incontrovertible evidence of aliens on Earth, either now or in the past. This is called the Fermi Paradox. The lack of observational evidence for extraterrestrial intelligence is known as the ‘Great Silence.’[13]
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.
Loss can leave us with the feeling that we are no longer in control of our lives, a strong feeling of instability. We must understand our loss to cope and deal with what has happened. Jo Ann Beard the narrator and author of “The Fourth State of Matter” struggles with several losses throughout the text. She appears to deal with her instability by caring for her aged dog as if she was a sick child, when in reality Beard just wants her problems to disappear. When faced with a complication a difficult choice must be made, to do nothing in hopes the problem will resolve itself or face it head-on. When pretending the problem doesn't exist or similarly telling yourself it will go back to how it was, simply allows
Since the beginning of time itself, man has been dreaming of time travel. The current model of physics shows no obvious doubts towards the possibility of time travel, which leaves many questions (“Quantum Time Travel”). If the quarrel for time travel holds any truth, how will man manifest the means of going about it? Before the theories set forth by the men and women in the scientific community can be understood, one must have at least a general knowledge of the basics behind quantum mechanics, as well as the estimable; Einstein’s, theory of space-time. Also, in a world where time travel occurs, there is the possibility of a paradox, or impossible situation caused by the travelers’ actions. Many answers to the paradoxes have been set forth by notable people. Possibly the most widely accepted theory of time travel, Einstein’s black hole theory, still holds prevalence to this day. Some other theories have come to light recently, and most are yet to be disproved.
...at this book should be included with all works that hold a high literary merit. This book appeals to a wide scope of people; it relates the complicated aspects of physics in a manner that can be understood by much of the general public. More than that, this novel gives the reader a glimpse into Feynman himself. The reader can now see how he thinks and functions, additionally, it allows the reader to preview what it may have been like to be in one of Feynman’s classes. This man is considered a modern day genius, and just the chance to further see what he is actually like, is something that allows for this book to be valued more highly.
The Ultimate Nature of Matter. 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.
Metaphysics can be defined as an attempt to comprehend the basic characteristics of reality. It is in fact so basic that it is all inclusive, whether something is observable or not. It answers questions of what things must be like in order to exist and how to differentiate from things that seem real but are not. A common thought is that reality is defined as what we can detect from our five senses. This type of philosophy is called empiricism, which is the idea that all knowledge comes from our senses. An empiricist must therefore believe that what we can see, touch, taste, smell, and hear must be real and that if we can not in fact see, touch, taste, smell, or hear something, it is definitely not real. However, this is a problem because there are things that are real that cannot be detected by our senses. Feelings and thoughts can not be detected, so according to a true empiricist, they must not be real. Another example that is listed in the textbook is the laws of gravity (Stewart 84). This is something that is in fact proven and we can see the effects of it, but we can not see gravity itself. Once again, this would not be considered to be “real.” However, there are certain things that some people consider to be real, and others consider them not to be. This typically comes into play when discussing religion. Some people consider God to be real although they can not “sense” Him and others say that He is not real, possibly because of the fact that they can no...
Informative Speech Scientists Einstein and Heisenberg A. Introduction My Speech is about the scientists who had the main influence on our current time and have shaped our contemporary view of the world (Also called in Theology the "Zeitgeist"). I have chosen two of them who are in many ways just opposites. One is extremely famous and the other is almost unknown, except to specialists. The most famous is, of course, Albert Einstein.
Werner Heisenberg was the first to realize that certain pairs of measurements have an intrinsic uncertainty associated with them. For instance, if you have a very good idea of where something is located, then, to a certain degree, you must have a poor idea of how fast it is moving or in what direction. We don't notice this in everyday life because any inherent uncertainty from Heisenberg's principle is well within the acceptable accuracy we desire. For example, you may see a parked car and think you know exactly where it is and exactly how fast it is moving. But would you really know those things exactly? If you were to measure the position of the car to an accuracy of a billionth of a billionth of a centimeter, you would be trying to measure the positions of the individual atoms which make up the car, and those atoms would be jiggling around just because the temperature of the car was above absolute zero!
Spectroscopy Spectroscopy is the study of energy levels in atoms or molecules, using absorbed or emitted electromagnetic radiation. There are many categories of spectroscopy eg. Atomic and infrared spectroscopy, which have numerous uses and are essential in the world of science. When investigating spectroscopy four parameters have to be considered; spectral range, spectral bandwidth, spectral sampling and signal-to-noise ratio, as they describe the capability of a spectrometer. In the world of spectroscopy there are many employment and educational opportunities as the interest in spectroscopy and related products is increasing.
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.
Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose name is known by almost all living people. While most of these do not understand this mans work, everyone knows that his impact on the world is astonishing.
