Once this has been discussed, it is somewhat easier to translate Einstein's concept to the poet's own courageous scientific imagination, as scene in the scene from "eowulf" previously mentioned. Just as the modern scientist, the poet introduces and, subsequently, tries to understand and explain, the idea of chaotic events, events that cannot be explained by the traditional ideas.

Despite his own behavior aimed at avoiding conflict, eowulf cannot control all the forces and objects/individuals in his realm. This is why the conflict is triggered by one of his men ("ut a certain man / stumbled on it,/into the heathen hoard,/and took a cup,/a large, decorated treasure"). As mentioned, the event itself lacks the previous logic according to which the battles were fought because of the unprovoked attack of the enemy (Grendel, Grendel's mother).

Here, the event cannot be explained by the previous laws of physics (the attack is not caused…… [Read More]

Words: 788 Length: 3 Pages Document Type: Essay Paper #: 33900558

Working Disciplines

Education in today's institutions is fragmented. Attempts at holistic and comprehensive understanding tend to fall short of practical usage consistently and often tragically. The purpose of this paper is to explore the discipline of physical science and how it relates or doesn't relate to other disciplines that are found in current academic studies. In this essay I will explore the difficulties and shortcomings of educational attempts to correlate and ultimately make sense of multi-disciplined explanations and knowledge.

Humanity has been blessed with the ability to communicate complex ideas and artistic expression. The goal of education is to organize and utilize these forms of communication in order to practically improve the human condition. This appears to be a very difficult task. Physics is a discipline which focuses on the reactions of strictly material influences. This discipline attempts to explain physical forces and to predict their outcomes. Why then is…… [Read More]

Properties of Light

Words: 2011 Length: 6 Pages Document Type: Essay Paper #: 49230270

Properties of Light

Light is one of the most basic physical phenomena. It is observed by most people on a daily basis, and even people who lack formal understanding of the properties of light have some understanding of its properties. For example, most people have seen mirrors, rainbows, and know that glasses can improve vision, though they may not understand that reflection of light explains how mirrors work, that dispersion explains the formation of a rainbow, or that refraction of light is used to form optic lenses. This paper will describe the various properties of light and explain how it acts in various mediums. It will discuss: the nature of light, which is a particular but behaves like a wave; color; velocity; refractive index; reflection; refraction; dispersion; total internal reflection; diffraction; and interference. Taken together, these various properties help explain how light functions.

Light is a form of electromagnetic radiation.…… [Read More]

The espected physicist Stephen W. Hawking attempts to intoduce the aveage laypeson to the physical pinciples of the mateial univese in his book entitled The Univese in a Nutshell. Hawking is pehaps best known to the wold as the late 20th centuy's most compelling image of pue scientific genius, as Albet Einstein was the most compelling image of genus fo scientific aficionados duing the fist half of the 20th centuy. Of couse, Hawking took issue with some of Einstein's basic concepts. Hawking is famous fo this bit of scientific daing. Hawking is also famous fo possessing a billiant mind, encased in a body that has unfotunately been sticken by a teible neuological condition that paalyzes his ability to feely move and speak -- although, as this book makes clea, not to wite.

references to how understanding physics can impact human life on earth in the relative short-term as well as in space and far into the future. Hawking describes how statistical evidence points to the physical limits of population growth and electricity being reached on earth by the year 2600. But by applying the same statistical principles to knowledge as to population growth, to take a more comforting view of things, predicted human knowledge of how to preserve energy reserves could potentially carry the human race forward, faster to possibly attain solutions to this problem of geometric physical expansion.

There is, however, no question that having some background in physics helpful in understanding the text, even while Hawking tries to simplify basic quantum principles. For instance, as the author attempts to explain the rational behind an early and inaccurate Michelson-Morley experiment, when humans imagined that space was filled by a continuous medium called the "ether," he must go into a lengthy explanation how early physics saw "light rays and radio signals were waves in this ether, just as sound is pressure waves in air." (2) In this experiment, because no difference was found in the speed of the two perpendicular light beams, the experiment's observers concluded that ether was non-existent. Still, for a man bounded, essentially, in his own physical nutshell, Hawking has accomplished and understood a great deal in his life and is able to make at least a small 'kernel' of what he as understood, interesting and comprehensible in concrete, physical terms. Also, his book functions as a shorthand introduction to the history of physics, and the different people and concepts that played a role in physic's conceptual evolution over the short distance of human historical time.

Inductive and Inventive Science

Words: 899 Length: 3 Pages Document Type: Essay Paper #: 69326111

ability to measure and track the results from any scientific experiment is extremely important to both the validity and truthfulness of the work. Scientists often have problems in certain sciences due to the scope of their investigation. As a result of these mismatches, indirect avenues of approach become necessary to measure and grasp the items of inquiry.

In physics, the atomic theory is based upon indirect measurements. The neutron, proton and electron are merely ideas that have been modeled due to the technology that is available to scientists. An electron has never been physically produced and only its characteristics have been noticed. This is an important distinction, because too often scientists take many of these long standing practices for granted and have assumed the presence of these particles, when there is compelling evidence there is not.

Interestingly enough, though, what is it that is so aesthetically pleasing that we want there to be a single theory of everything -- why does everything need to be explained in one fell swoop? This idea of a Theory of Everything is becoming more philiosophical than scientific. Aristotle and Plato were unsuccesful in their attempt to make a theory work, and Hawking said, in A Brief History of Time, that even if we had a Theory of Everything, it would necessarily be a large set of equations. "What is it that breathes fire into the equations and makes a universe for them to describe?"(Hawking in Fletcher, 2008, 196).

Now, though, Hawking has revised his views. In the new book, The Grand Design, Hawking and Mlodinow (Caltech physicist) argue that it is a set of equations that will, indeed, tie theories together, but that a final theory may never have a…… [Read More]

Using both at the same energy improved temporal resolution, best used in cardiac imaging. hen used at different kilovoltages resulted in material differentiation (Vlahos 2007).

This dual-energy scanner, based on different attenuations and different photon energies will likely be used for pulmonary arterial angiographic and aortic imaging with, potentially, lower contrast volume. It will also likely be used for pulmonary enhancement maps and may possibly eliminate precontrast imaging and reduce radiation exposure (Vlahos 2007).

Utilizing the distinguishing qualities of attenuation, consistency or homogeneity, number and size of tumors found in Positron Emission Tomography (PET) scans of lungs and thyroid, pancreas, kidneys, adrenals, liver, and ovaries can be evaluated with training.

Sir Isaac Newton

Isaac Newton (Bio, N.d.)

Sir Isaac Newton is one of the most recognizable names in all of science. He was a mathematician, a natural philosopher, an inventor, an English physicist, and pretty much an all around genius. His work included the study of how light reacts to reflection, formulating laws of universal gravitation and motion, and building the first ever reflecting telescope. Newton arguably contributed more to the science than any single person in the entire history of science. Newton's book, Principia, is considered to be among the most influential science books in the history of science, possibly of mankind. In this book he provided the foundation for classical mechanics. Newton described universal gravitation and the three laws of motion which have been the background of classical physics for over three centuries. Since Sir Isaac Newton was such an influential mind, I thought it would be…… [Read More]

Hitchhiker's Guide

ouglas Adam's comic work of science fiction, The Hitchhiker's Guide to the Galaxy, satirizes both society and science. As the story opens, protagonist Arthur ent is railing against the local government for its decision to raze his home, which is in the way of highway construction. ent argues that he was never made aware of the decision, though officials assure him the plans had been on display for a sufficient amount of time, albeit "on the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard'"(Adams 2010, p. 9). Similarly, planet Earth is in the way of hyperspace bypass construction project, for which plans were also available for review. Bureaucratic red tape ensured the plans were never seen and ent flees the planet with his alien friend Ford Prefect before it explodes. They hitchhike their way…… [Read More]

Dent and Prefect travel through space by hitchhiking, picked up by spacecraft within the improbable nanosecond during which contact could possibly occur. They travel from planet to planet in a "nothingth of a second," making their travel faster than the speed of light, given the distances over which they traverse. Although this mode of travel has been theoretical supported by the theory of special relativity, it has obviously never been done except within the pages of books such as Adams's. In reality, it seems as improbable as Adams' physics of improbability.

Some of the science in Hitchhiker is accurate, or nearly so. Dent's alien friend is from a small planet "six hundred light-years away in the near vicinity of Betelgeuse" (Adams, p. 22); Betelgeuse is, in fact, 640 light-years from Earth. On page 26, the Vogons admonish Earthlings for failure to involve themselves in the "local" affairs of Alpha Centuri, "only" four light years away; Alpha Centuri is 4.4 light years away (Dickinson 1999, Tyson, Liu and Irion 2000). On page 60, Adams refers to "a nice hot cup of tea" as an example of a strong Brownian Motion producer. Brownian motion refers to the random movement of particles suspended in a fluid. Tea could, in fact, serve as an example.

Some of the science is deliberately ridiculous, such as the computer called the "Bambleweeny 57 Sub-Meson Brain" (Adams, p. 60). Adams also blends science and satire. On page 33, he lets the alien Vogons debunk the theory of evolution by having them ignore nature and have elective surgery to "rectify the gross anatomical inconveniences" that made

In this interpretation Heitler accepts the modified Copenahgenist observer created reality, but adds that the act of observation dissolves the barrier between observer and the observed. The observer is a necessary part of the whole. Once observed, the object is now an inseparable part of the observer (leuler). Arntz addresses this bridge between the observer, the observer, and reality by asking "why aren't we magicians?"; indeed, if we create our reality and can change our reality simply through the act of how we perceive it, and how we choose to perceive it, we should be able shape our world and our place in our world. In Arntz' way, he is offering to the reader what so many self-help gurus have done -- put responsibility for one's reality in the hands of the person living that particular reality, and saying, 'here you go, you can change it.'

Bohr's work on the structure of atoms was awarded in 1922 with the Nobel Prize. After 1930, the activities within his Institute were increasingly focused on the constitution, transmutations, and disintegrations of atomic nuclei, and further developed an understanding of nuclear fission permitted by the "liquid droplet theory." These activities formed the basis for important theoretical investigations of nuclear physics that followed.

Problems encountered with quantum physics were clarified through contributions to the field made by Bohr. In particular, Bohr developed the "concept of complimentarily," whereby he demonstrated how the scientific outlook of the general populace has been greatly affected by changes in the field of physics, and how the scope of atomic physics reaches throughout all facets of human knowledge.

Isaac Newton is a renowned mathematician, scientist, inventor, professor, and public official who influenced the world of science with his extraordinary and brilliant theories on different phenomena in (primarily) the study of physics, astronomy, and optics. Born on the 4th of January, 1643, Isaac Newton's life as a young man in Woolsthorpe, Lincolnshire in England is unremarkable, and Newton, at a young age, did not show and possess the brilliant mind that he has while attending a formal school education at the Free Grammar School in Grantham (O'Connor and obertson 2000). As a child, Newton did not seem to possess the intellectual strength that he was known for, and had a hard time living with his family during his childhood years because of the constant tension between him and his stepfather and mother.…… [Read More]

Scientific Principles: "Timeline in Optics"

It is very clear that Optics is the physical science that examines the source and broadcast of light, how it fluctuates, what effects it yields, and other marvels that are connected with this interesting science. Many science nerds may be unaware that there are two divisions of optics. One of those divisions is called the Physical optics. The physical optics is related to the properties and nature of light itself. Also, it is clear that the geometrical optics are what concentrates with the principles leading image-forming assets of mirrors, and lenses, other devices, for example optical data computers.

This "Timeline in Optics" puts the emphasis on important developments and events in the science of optics from prehistory to the start of the 21st century. It likewise consist of associated expansions in other fields (the evolution of processors) and interconnected highpoints in the human worldview.

Quantum Tunneling Is a Function

Words: 2304 Length: 8 Pages Document Type: Essay Paper #: 53098140

So increased voltage results in a drop in current. As the voltage continues to increase the junction begins to function as a normal diode as electrons travel by conduction through the p-n junction and no longer tunnel through it. Therefore the most important region for operation in a tunnel diode is the negative resistance area.

Used in reverse direction Esaki diodes are called back diodes and act as very fast rectifiers with a zero offset with extreme linearity for power signals and have an accurate square law characteristic in the reverse direction. As back diodes, with reverse bias at high reverse voltage, electrons actually flow in the opposite direction, as electron states on each side of the p-n junction become increasingly aligned, allowing electrons to tunnel through the p-n junction going the opposite direction -- this is called the Zener effect which also occurs in zener diodes.

The theory of relativity would go on to have tremendous impact on the modern world, from philosophical speculation and "relativity" to nuclear physics and the creation of the atom bomb.

In conclusion, the Michelson-Morley experiment, though repeated for nearly half a century later (and still replicated by students such as Rogers and Selvaggi), erased the idea of ether as a medium through which light waves traveled. Although their experiment provided no proof of the existence of ether, the conduction of the experiment was not viewed as a failure, but rather as a success -- for it opened the door to new postulations, and ultimately to Einstein's theory of special relativity. For his experiments, Michelson was awarded the Nobel Prize in 1907. Yet, unhappy with his own tests, Michelson would participate in more experiments in the future, particularly with Dayton Miller. Even though Miller's tests showed evidence of ether, his experiments…… [Read More]

The Implicate Order and Explicate Order can be compared to a piece of holographic film and the image it produces. The film corresponds to the enfolded, or hidden, Implicate Order. The image, or hologram, (what is humanly perceived) is the Explicate Order. Thus, the tangible "reality" of our everyday lives is a kind of holographic image being projected from the "film" or source -- the Implicate Order (Dunlap, 2000).

The flow of time is part of the dynamic process of enfolding and unfolding. "As the present unfolds and becomes part of the past, it does not cease to exist, but simply returns to the cosmic storehouse of the implicate" (Talbot, 1990, p. 200). The event we call death is another example of what he is saying. Death is not the end -- it is simply moving out of the Explicate and into the Implicate.

Quantum mechanics is a theory that has emerged in the study of both chemistry and physics and has been received with a lot of enthusiasm. Nobel laureate physicist Philip Anderson goes as far as naming quantum mechanics the greatest invention of the last 2000 years, describing its impact saying,

The quantum theory forces a revision of our mode of thinking, which is far more profound than Newtonian mechanics or the Copernican revolution or relativity... It tells us that we really completely know the rules of the game which all these particles and quanta are playing, so that if we are clever enough we can understand everything about ourselves and our world. In other words, there is no "why" question about our everyday world that the quantum theory can't answer for is - Why is the sky blue? Why is glass transparent? What holds DNA together?

Dangling Particles, physicist Lisa Randall explains why the complexities and abstract nature of modern science only makes it even more incomprehensible to the layman. For example, virtually everything we know today about quantum mechanics at the smallest end of the spectrum of matter and everything we know about galaxy formation at the largest end of the spectrum requires advanced scientific training to conceptualize. A layperson relying exclusively on direct observation and on the traditional notions of the four dimensions cannot possibly understand what quantum physicists men by "strings" or about the nature or gravity and the particles whose theoretical existence allows scientists to deduce the existence of things (like additional dimensions) that cannot be observed directly in any way.

multiverse is a line of thought that that proposes the existence of multiple universes. The hypothesis advances the notion that the set of multiple universes are what together make everything that exists physically and ever existed. These include the whole concept of space and time and all the elements in the universe together with all the laws of physics and the constants that govern the laws. The multiple universes can also be referred to as the parallel universes. The relationship in a particular multiverse and its constituent universes within it depend on the certain multiverse hypothesis that is taken into consideration.

The hypotheses that explain multiverse are from various areas of study. Ranging from astrology, physics, philosophy, cosmology, and fiction. The word multiverse however, was coined by William James a psychologist in 1895. Other referrals have been derived to mean the same as multiverse.Such words include alternative timelines, alternative universes,…… [Read More]

After determining the resonance of the vowel sounds, Helmholtz set about reproducing them. He was no less clever here than he was in figuring out how to analyze the pitches of human speech. After completing this analysis, he combined the sounds of various combinations of pitchforks until he achieved the same resonance as the human vowel. No one before had ever mechanically reproduced human speech sounds in such a conscious and accurate manner before, nor thought of vowels as purely interactions of different pitches. Helmholtz combined a very objective mind and ear to a fantastic and precise knowledge of the physics of sound in order to develop these reproductions. His knowledge and research into physics was essential to his study, as sound is ultimately a physical phenomenon. But his research into the human biological ability to produce sound was also groundbreaking, proving the breadth of his knowledge and worth as…… [Read More]

Jay Pasachoff claims that Newton revolutionized astronomy by setting "modern physics on its feet by deriving laws showing how objects move on the Earth and in space" (Pasachoff 41). Simplistically, this is the train of thought that birthed the law of gravity. Newton was the first person to ever realize the "universality" (41) of gravity. Perhaps the most fascinating aspect of this creation involves that fact that in order for this new law of gravity to work, Newton had to invent calculus. His brilliance lies in the fact that he was able to connect the fact that the same force that forced objects to the ground was the same force that moved objects in space. He was able to comprehend how the moon was "falling" toward the earth. Newton developed his law…… [Read More]

Standard Construction of Modern High Field Magnets Used in Modern Nuclear Magnetic esonance Devices

Nuclear magnetic resonance devices are playing an increasingly important role in healthcare and research today. As the term implies, magnets, specifically high field magnets, are an essential part of these sophisticated devices with important implications for a wide range of valuable healthcare and research applications. To gain additional insights into how these devices operate, this paper provides a discussion concerning the standard construction of modern high field magnets used in nuclear magnetic resonance devices, including a detailed graphic illustrated the different components of a representative magnet. An examination of the effects of transitions to higher magnet strengths on cooling systems is followed by an analysis of the superconducting materials used and a brief description of magnet construction. A discussion concerning the differences between shielded magnets and non-shielded magnets and innovations in technology that may allow room…… [Read More]

Infinity - By George Gamow

Words: 1004 Length: 3 Pages Document Type: Essay Paper #: 35593630

" It is this ability of Gamow to take complicated science and serve it to the reader in interesting bites that earned him a reputation as not only a brilliant scientist, but as a fine writer.

After all, "in order to understand the problem of life in general," he writes (234), "we must look for the solution in the structure and properties of the living cells." And he while delves deeply into the science of cell structure and cell division, he nonetheless returns to concepts that the lay person can understand; on 238-239, he is pointing out that all human cells "contain exactly the same number of chromosomes" but scientists have used "the little fruit fly" to help them understand "many things concerning the basic riddles of life." The cells of a pea plant have 14 chromosomes, corn cells have 20, the fruit fly has 8, and humans (including biologists)…… [Read More]

Newton's Three Laws of Motion

Words: 769 Length: 2 Pages Document Type: Essay Paper #: 13864367

he second law, which states that rate of change of object's momentum is proportional to the force exerted upon it is the most practical law. his law is the logical continuation of the inertia law and explanation of Galileo's principle and transformations. Second law gives a prediction to what will happen with the object when a force acts on it: object's velocity will change and object will accelerate (with negative or positive acceleration). In order to understand the meaning of this law, mass is introduced. he mass of the object is a quantitative measure of inertia, which defines amount of matter contained in object. hat's why in modern interpretation the second law says that objects acceleration is directly proportional to the magnitude of the total force and inversely proportional to the mass of the object. hat's why mass of the object also defines object's resistance to acceleration.

In terms of…… [Read More]

Third law states that forces, which occur in pairs, are equal in magnitude, but are oppositely directed. Third law is mathematical conclusion of the law of conservation of momentum (as it can be stated that acceleration is a derivative of velocity and force is a derivative of momentum). Third law states that though forces of interaction are equal, accelerations may be different as masses of objects may be not the same.

Laws of Newton were proved more than 200 years ago on the base of everyday experiments and they serve as excellent approximation to kinematics and dynamics of objects in everyday life. These laws form the basis of classical mechanics, or mechanics of idealized macro world. They can be applied without errors to objects, which have speeds much smaller than relativistic speeds (speeds which are close to the speed of light). But even in relativistic world the form and essence of Newton's laws is preserved if relativistic space transformations are followed.'s_laws_of_motion

Ibn Sina

The great Avicenna or Abu Ali al-Husayn Ibn Abdullah Ibn Sina, born in 980 was often known in the est by this Latin name. Among all the Islamic philosopher-scientists this Persian physician became not only the most famous but also an influential figure (Edward G, 1921). He was awarded royal favor for treating the Kings of Bukhara and Hamadan for illness which other physicians were unable to neither diagnose nor cure. He died in 1037 in Hamadan, where his grave is maintained (Edward G, 1921).

Out of his 450 works, only 240 have survived and among those surviving works, 150 are on philosophy, while the remaining majority 40 works are dedicated to medicine. Thus, his major contribution was in these two fields. However, he has also written on psychology, logic, mathematics, geology and astronomy (atan Afghanistan).

Although, he was educated and trained in the field of physics, he…… [Read More]

Vectors are defined in the video as a very basic idea, anything that has size and direction is a vector, some examples are velocity, where force moves something with mass. Newton's second law F=ma is a description that includes two vectors, force and acceleration, The description of vectors in a static system where forces are balances and pushing against one another is also a great demonstration.

Dark matter is a video that leaves as many questions as if offers answers, but is probably my most favorite video as it discusses something that is extremely interesting and elusive. The fact that 95% of mass is either dark energy or dark matter and only about 4% is "normal" matter (containing everything we know) is a staggering statistic. The fact that everything we know is affected in some way by electromagnetic energy and that dark matter is only very limitedly affected by or…… [Read More]

Transporter Technology Transferring Light Over

Words: 3956 Length: 12 Pages Document Type: Essay Paper #: 53959622

It is so much a copy that one could call it a clone of the original; in other words, it is a second original. If matter were to be thus transported, then we would have two of the original objects, should one be transported.

Alternative theories, based on the Heisenberg Uncertainty Principle, would be best followed up, if matter is the stuff which one wants to transport. The Heisenberg Principle states that it is impossible to know where any part of a physical object is at any point in time. Therefore, to know where every atom of our body is at any given time is impossible. If your blood is moving through your veins, then the atomic particles which make up your blood are moving rapidly from one part of your body to another and it is impossible to know at any particular moment where one of these atoms may…… [Read More]

Moreover, his theories regarding the gravitation were supposed not to have been made possible without the attempts of his predecessors, as Galileo, to understand the world. Thus, Newton's luck may be put on the fact that he has lived in a period of discoveries, and, as he himself stated, he had seen further than other men, it is because he stood on the shoulders of giants.

All in all, Newton has been considered for almost 300 years to be the founding father of modern physical science, his discoveries being unprecedented, just as those in mathematical research. eing a polyvalent personality, he also studied chemistry, history and theology; his main method in all domains being the investigation of all forms and dimensions.

Scientific Inquiry Into Extraterrestrial Life

Furthermore, he argues, a technological culture is not an inevitable feature of human evolution. If other cultures had achieved ascendancy, then science and technology would not have emerged as a reference point for measuring intelligence. SETI's requirement for an almost identical technology, although scientifically understandable, is based on an impoverished concept of intelligence.

According to Munevar, the development of a scientific culture, with access to radio communication, is highly contingent, requiring a number of lucky breaks from the environment and human natural and social history. In this context Munevar cites the development of mammalian intelligence. It is widely believed that the dinosaurs were wiped out by the immediate effects of an asteroid or cometary impact or possibly volcanic eruption. But mammals who survived the years of darkness caused by the dust of the impact or eruption then evolved to occupy the niche held by the dinosaurs. If the dinosaurs had…… [Read More]

Absolute Determinism

Questions about place and role of reason puzzle generations of philosophers as they are among the fundamental questions of philosophy. In case it appears that everything is planned and all events are mutually connected it may witness for the divine origin of the universe and man. Laplace proposed the theory of absolute determinism which stated that every process which took place in the universe had a reason so that the next or previous stage of this process could be predicted and described in the absolute form.

Determinism of Laplace had a lot of strong points at the time when he developed this theory. First of all Laplas was a mathematician and physicist and the principle of sufficient reason corresponded to all dynamic processes he studied: motion, oscillations, etc. This principle laid in the fundamentals of classic mechanics and was applied for any dynamical system on the hand with…… [Read More]

Communication History

Fans of science fiction are fond of recalling a remark by novelist Arthur C. Clarke, to the effect that any sufficiently advanced technology is indistinguishable from magic. I am currently typing these sentences onto a laptop, where I am also currently watching a grainy YouTube video of the legendary magician Harry Houdini, performing one of his legendary escapes -- from a straitjacket, in this case. Houdini is probably the most famous stage magician of the twentieth century, as witnessed by the fact that his name is familiar to my generation although he died almost a century ago. If Houdini were to suddenly reappear in front of me right now -- in the flesh, I mean, and not merely on YouTube -- how would I explain to him that the way in which all of this is taking place? To someone who has been dead for a century, the…… [Read More]
