Quantum Computers
The beginning of quantum computers came at the turn of the twentieth century when there was a scientific revolution and quantum mechanics was born. Quantum computers are based off of the mathematical framework of quantum mechanics and have a multitude of uses that are applicable in today’s world and the futures. Quantum computers have the possibility of processing numerous complicated efficient algorithms at one time by harnessing the power of the atom. Current quantum computers have the ability to be used in today’s world, however, their true power has not yet been harnessed because several complications with the use of atoms.
The modern theory of quantum mechanics was born in the 1920’s. Quantum mechanics is a mathematical framework or set of rules for the construction of physical theories and is the foundation of the quantum computer. It is an indispensable part of science and has been applied to the structure of the atom, nuclear fusion in stars, superconductors, the structure of DNA, and the elementary particles of nature (Nielsen 2).
Since the 1970’s developments in techniques for controlling single quantum systems have occurred. For example there have been methods developed for trapping a single atom in an ‘atom trap’, which isolates the atom from the rest of the world and allows scientists to probe many different aspects of its behavior with incredible precision. These methods help explore untouched regimes of nature in the hope of discovering new and unexpected phenomena. The ability to control single quantum systems is essential to harnessing the power of quantum mechanics for applications to quantum computation and quantum information (Nielsen 3).
In 1982 Richard Feynmen considered simulation of quantum mechanical objects by other quantum systems. In 1985 David Deutsch wrote a crucial theoretical paper in which he described a universal quantum computer which uncovered the unusual power of quantum computation. In 1994 Peter Shore devised the first quantum algorithm that could perform efficient factorization which underpins the security of all encrypted information (QUBIT).
The discovery of quantum mechanics was revolutionary because it is counter-intuitive to classical physics. For example, if person A is standing on a train going twenty miles per hour with a flashlight pointed straight ahead and person B is stationary on the ground with a flashlight pointing the same direction as person A, one would think that the light coming out of the flashlight of person A is twenty miles per hour faster than the light coming out of the flashlight being held by person B.

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.
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.

Having an experience /activists/ – they are the go-getters rather than intellectuals and they prefer the actual experience itself.
The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.
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.
Countries such as Brazil and Indonesia have been greatly affected by deforestation with well over two million hectares of naturally forested land now rendered barren (See appendix 1).
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
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.
Pride and Prejudice, one of Jane Austen’s masterpieces makes use of satire to promote social change, because the English society of the 19th century only saw marriage as a ticket that would help you move upward on the social ladder. Throughout the book, the reader gets front row seats as Austen mocks both the conservative middle class and upper class, giving the dissentient characters a chance to be seen in society with a better image. Austen expresses her feelings on why social changes must occur to her audience by making use of satire to describe Mrs. Bennet, Mrs. Hurt, and Miss Bingley in comparison to the way she develops characters such as Elizabeth Bennet and the wealthy gentleman Fitzwilliam Darcy. Furthermore, while the reader gets to witness dramatic moments from Mrs. Bennet, Mrs. Hurst, and Miss. Bingley as they strive to comply by the traditions of the 19th century, Elizabeth and Mr. Darcy play a significant role in trying to demonstrate to the reader on why love should be the chief reason for marriage.
Scientists themselves are just beginning to understand the serious problems caused by deforestation. Deforestation occurs all over the world by all types of people. Peasant farmers even add to the problem because in most tropical countries the farmers are very poor only making between eight hundred and fifty four hundred dollars annually (NASA Facts). Therefore, they do not have enough money to buy what they need to live therefore they must farm to raise crops for food and to sell. In these poor countries the majority of people are peasant farmers this farming adds up to a great deal of deforestation. These farmers chop down a small area of trees for there plot to farm on and burn the tree trunks (NASA Facts). The combined number of farmers maintaining this process creates a great deal of clearing and burning of the land they need to cultivate, which results in land being treeless. Commercial logging is also another common form of deforestation. This commercial logging wipes out massive amounts of land sometimes deforesting several miles at...
Urbanization, or the clearing of land to build, is deforestation done in the name of progress. Land has been cleared for centuries to make way for the building of cities and homes. In fact, the lumber itself is used for shelter and the furniture within it. Industrialization can also be included here. Industries often cause air pollution. Without sufficient trees to process the CO2, the air we breathe contains harmful chemicals that thicken the atmosphere and hold in the radiation from the sun’s rays, which in turn warms the planet.
