Elemental Isotopes and Allotropes
The 19th century discovery of the periodic table of the elements by Dmitri Mendeleev gave an organizing principle to understanding the structure of the atom, and deriving atomic weight. On the periodic table, the lighter elements have atomic weights which correspond to whole numbers. Hydrogen has an atomic weight of 1, which corresponds to the idea that it has only one proton (and the weight of an electron is statistically insignificant in this measurement). But moving further along the periodic table, it became clear that the numbers eventually became less predictable. In the 19th century Dalton had suggested further atomic weights were simply multiples of hydrogen, which to a certain degree matched the available evidence.
But it was the discovery of the neutron in 1932 that actually yielded the correct answer. Rutherford had hypothesized the existence of an extra particle in the nucleus that…… [Read More]
Andrew Cuomo is a Democrat elected to Governor of New York State (Green N.Y.). He believes in a strategy that stems back to the Obama administration, involving reformation of the energy sector of New York to facilitate the recovery of the economy (Cohen, 2011). Cuomo champions for a lower carbon emission energy that is "greener" and better environmentally, that also stimulates the economy as it creates more jobs and becomes more technologically innovative.
Even though energy policies are enacted on a global level, Cuomo believes that there is much to be done on the state and local level (Cohen, 2011). In regards to the state level, Cuomo's energy plan calls for a new age in energy, calling for more efficient ways to transfer energy through a better infrastructural grid that includes a system of energy renewal. He also calls for major state government system reform, because the current…… [Read More]
Physical Science: Energy
How Energy Can be Converted from one Form to Another, ith Examples
"Energy" is defined as the capacity to produce changes within a system. ithin a system, energy can be changed to a different state in order to perform work in natural processes or machines (Shipman, ilson, & Todd, 2009, pp. 88-89). Plants, animals and machines all convert energy to perform work in their processes. Through Photosynthesis, green plants use Chlorophyll, composed of miniature energy factories called Chloroplasts, to convert solar energy into storable chemical energy as a sugar called Glucose (Nave, Pigments for photosynthesis, n.d.). In the body of an animal or human, the cells' energy factories, called Mitochondria, contain Organelles, which convert chemical energy stored in food into Adenosine Triphosphate (ATP), which is the energy used in life processes (Nave, Mitochondria, n.d.). An internal combustion engine, such as a car's engine, converts the potential chemical…… [Read More]
Physical Science: Heat
It is reasonable to suggest that just about everyone has felt the warmth of the sun or warmed themselves by a fireside, but many people may not understand the source of the energy they are feeling, particularly at the molecular level. Without heat, though, humankind would soon cease to exist and the universe would quickly collapse into an absolute zero nothingness. To gain some further insights into this essential source of life, this paper provides a review of the relevant literature to define heat and temperature, the relationship between them, and how they are different. A discussion concerning the various properties of a substance that determine its heat capacity is followed by a description of some of the various sources of heat. Finally, an analysis concerning how the study of heat relates to the kinetic theory of matter is followed by a summary of the research and…… [Read More]
Describe the difference between a mixture and a compound
For basic understanding, a mixture comprises of two or more different substances which are not chemically combined to each other. On the other hand, a compound consists two or more chemically bonded different substances which are present in a fixed ratio. In other words, the difference between a mixture and a compound is evident from the mentioned definitions.
Furthermore, there are a number of ways in which a mixture and a compound differs. For example, compounds always contain elements in a fixed ratio. For this reason, Calcium Carbonate, a compound, would always contain 40% Calcium, 12% Carbon and 48% Oxygen by mass. No variations in the mass of these elements would be noticed in Calcium Carbonate. In contrast, a mixture would contain its substances in any proportion (example: salt and water). For this reason, a mixture can…… [Read More]
Procedures in the Physical Science
Procedures in the Physical Sciences: Challenges in Measurements
Identify three (3) specific challenges to making direct measurements in the fields of astronomy, chemistry, physics, or earth science. Describe how scientists have utilized indirect forms of measure to overcome these challenges.
Ever since the ancient times, individuals have always been pulled into the unknown. Human beings have always been inquisitive in regards to everything that was going on in the world. They would ask question such as the following; is the earth a certain size? Is the sea really deep? Are there any other lands past the distance? And how what is the size of the universe? These kinds of questions have continuously directed people to start getting their minds to think and figure out what was going on. Until these current days some of these questions are still in the back of their…… [Read More]
Biology autonomous from physical sciences?
Background of debate
Biological science has undergone a time of progressive change in the last few decades. A distinctive element of this progress has been a continuous addition of fresh theoretical points-of-view and methods from physics and chemistry (the physical sciences). The most interesting fresh innovations in contemporary Biology are closely linked with how these new theories and methods are applied. There is a unanimous consensus that a lot of the phenomena that used to occur naturally in the arena of biological science has been overridden by a science that is practically physical. The exact reference of the new expanded theories such as 'biophysics', 'biochemistry', and 'molecular biology' apparently point to new knowledge for treating the science of life on earth as chemical and physical principles (Hansen. 1969)
What is Biology?
In an attempt to answer this question, it is worth noting that biology is…… [Read More]
Bob Berman's book Secrets of the Night Sky: The Most Amazing Things in the Universe You Can See with the Naked Eye is one of the most interesting and engaging books that I have ever read on the topic of astronomy.
The book is geared toward beginning astronomers, but its humorous and interesting prose makes it a great read even for those with more advanced knowledge of the cosmos.
The book is a wealth of information, and takes the reader on an engaging tour of the night sky. Berman points out highlights and interesting information on the history of astronomy throughout. Further, he dispenses practical advice and tips in a warm and helpful manner. The book offers a helpful and informative guide to the visible universe in a logical and easily understood season-by-season format.
Berman covers a lot of ground in this introductory offering. The book is organized as a…… [Read More]
Technologies like array tomography also show how the human brain may be best understood as a computer that operates on both electricity and on chemicals. One section of the brain, the cerebral cortex, contains more than 125 trillion synapses. Boyle's (2010) source material from the Stanford School of Medicine notes that the number of synapses in the brain is "roughly equal to the number of stars in 1,500 Milky Way galaxies," (Goldman 2010).
Array tomography as a visualization instrument also reveals advancements in digital imaging as well as nanotechnology. The mouse brain used in initial array tomography experiments was sliced at only 70 nanometers thick (Goldman 2010). Measured at the level of the nanometer,, the layers of the brain that can be cut and then imaged with array tomography are small enough that scientists are able to understand more about how the brain works. Without technologies like array tomography, the…… [Read More]

MOISTURE-RELATED HABITAT PREFERENCES IN ISOPODS
PROJECT DESIGN PLAN
Isopods -- also known as "sowbugs" or "pillbugs" -- are usually mistakenly thought of as insects. In reality they are the only terrestrial species of crustacean, and are evolutionarily more related to crabs, shrimp and lobster than any kind of "bug."
This evolutionary relationship to so many aquatic species -- and the dearth of land crustaceans besides the isopods -- raises interesting questions about the isopod choice of habitat.
Crustaceans obviously have a system of underwater respiration using gills. Isopods also have these gills but do not live underwater: they are predominantly found in moist damp environments (beneath a rotting log).
But could isopods live underwater if necessary, or are their gills fully adapted to land life now?
I proposed an experiment to determine habitat preferences in isopods. It would offer a representative sampling of isopods…… [Read More]
Physical Attraction in the Internet Age
Since its inception the internet has affected nearly every aspect of society so it is only natural that it would eventually impact on our most intimate of relationships: romance. In just a short twenty years the internet has nearly revolutionized the dating process and determined who and how we meet each for purposes of establishing both casual and permanent romantic relationships. The internet dating business is one of the few to not only survive but also prosper in these precarious economic times (Carpenter). By 2012, the industry is expected to reach $1.9 billion in consumer sales (D. Card).
In the context of this paper internet dating is defined as the use of a database of potential dating partners, usually located in close geographical proximity, to find someone with whom one feels some connection.
The format of most dating services is similar. The sites, whether…… [Read More]
The release of fossil fuels has been driving industrial and civic expansion for the past century and a half, and there is therefore a compelling reason to deny such causes: "some corporations whose revenues might be adversely affected by controls on carbon dioxide emissions have also alleged major uncertainties in the science (Oreskes). Just as in the debate over the heliocentric solar system, issues of political and/or economic motive are raised to cloud the science at issue.
hat truly separates the global warming debate from the issues that Galileo dealt with, however, is that there really is hard science at the base of both camps with vastly different interpretations. This has made the contention all the more fierce, and personal accusations only seem more rampant now than during Galileo's trial due to the increased difficulty of a scientific attack. One example of this is Gore's insistence on using Revelle's name…… [Read More]
This type of evolutionary thinking will challenge the initial creationist act as well. Many creationist currents, including the Christian one, believe that human life was also created through divine intervention, so any kind of such approach where life actually evolved to form the human being along the way takes away the special characteristics of human kind, as perceived by Christianity, for example. So, evolutionism virtually challenges the entire theological belief on the history of Earth and its inhabitants.
4. Logical positivism is based on general skepticism towards mythology, theology or metaphysics and on the idea that all true facts can and have to be verified in order to become veridical. In this sense, besides empiricism and materialism, verificationism is also one of the pillars on which logical positivism is based.
For a fact, proposition or idea to be cognitively meaningful, it has to be able to follow a particular path…… [Read More]
Otherwise, one field risks becoming subordinate to the other; although it's likely that Coyne's theology is extraordinarily sophisticated, the brief excerpt of it that Bill Maher uses leads the viewer to suspect that if these precepts are followed to their logical conclusion, religion will always give way to science as John Paul II gave way to the certainty that organisms evolve over time.
If so, then efforts to restore faith to a more equal footing are naturally vulnerable to claims that they are reactionary attempts to usurp science's rightful and supreme interpretative role in modern life. It is easy to understand Richard Dawkins' profound revulsion over what he sees as resurgent religiosities surrounding Islamic fundamentalism on the one hand and Christian fundamentalisms on the other: These faith-oriented responses to world events pose an implicit challenge to his own conviction that all aspects of experience are the product of physical entities…… [Read More]
or, to put it another way, "chemistry carried out with the primary object of investigating the workings of nature is what we now call physical chemistry" (Laidler, 5). This has made the distinction between physics and chemistry at this frontier very difficult to define. This fuzzy distinction is also one of the things that makes the discipline of physical chemistry so interesting -- it cannot deny the complete interweaving of scientific disciplines.
Physics and chemistry lay out the foundation and explain the mechanisms of all other sciences, and the field of physical chemistry is the closest unification of these two sciences. All biological and astronomical processes only occur because of reactions and interactions at the molecular and atomic level, and physical chemistry attempts to explain these underlying principles (Laidler, 9). Though the nature of energy and matter is still not fully understood, physical chemistry is approaching better and better explanations…… [Read More]
Science of Behavior Change
NIH Common Fund Programs: The science of behavior change
The science of behavior change is a critical area of NIH research because of the degree to which lifestyle changes can improve human health. Chronic diseases such as heart disease, type II diabetes, and stroke have all been linked to negative health behaviors like smoking and drinking. Only if scientists can understand how to motivate people to change their behaviors can a more effective prescription for remedying these ailments be constructed for our nation. Two NIH studies currently being undertaken are one which investigates how "environmental and biological factors associated with poverty and stress that underlie abnormal impulsivity that accompanies addiction to substances and unhealthy behaviors" and one which assesses environmental factors that influence the propensity for adolescents to exercise " to identify individual differences in voluntary exercise behavior and inform new ways to change exercise behavior…… [Read More]
During the gene decoding process the double stranded DNA splits up to reveal a single strand from which the base sequence of the gene is copied onto a single stranded nucleic acid known as the messenger ribonucleic acid or mRNA. This implies that we have an exact copy of the gene base in the mRNA except that Urasil (U) replaces the T. base and deoxyribose is replaced by ribose. Translation on the other hand is the actual process of protein synthesis from the mRNA strands. Ribosomes work with the mRNA for protein synthesis within the cells. [the State University of New York]

In the last fifteen or so years the concerns about vaccinations, and particularly the combined measles, mumps and rubella vaccination (MMR) have come to the forefront of societies debates from a limited connection to autism that is most likely associated to the correlation between onset of symptoms of autism and autism spectrum disorders and standard immunization practices. The fear created a general public that was afraid to allow their children to get the life saving MMR and in turn many parents have denied their children vaccinations at all. Parents' fears of some connection between the vaccination and/or its ingredient makeup cause or trigger autism and an accompanying serious bowel disease is related to a single, very limited research study conducted in the UK (n 12). There has been a substantial increase in incidents of autism over the last 20 or so years and the extreme social, physical, emotional, financial and…… [Read More]
An object's heat capacity is the product of its precise heat capacity, which is the quantity of heat necessary to raise 1 kg of the material one degree, and it's mass in kg. Heat capacity is a widespread property of a matter. In other words its worth varies depending on how much matter is present (Jorgensen, 2011).
What are the various sources of heat?
The sun is an element of the solar system. Therefore, it is a natural source of heat energy. Sunlight is significant for the survival of all living things. This type of heat energy is also known as solar energy.
The heat energy that is obtained from the Earth is known as geothermal energy. Sustainable and unsoiled geothermal energy can be obtained from the hot water and rocks that are located in the shallow ground. It is also located in the molten rocks obtainable in the farthest…… [Read More]
" But these close connections cannot be developed over the phone alone. It is important that a person stays in close personal contact with friends and family by visiting them often.
Science and technology have not only affected our daily lives, they have significantly altered our social systems as well. We are not investing in our societies and communities as our forefathers used to. For example, if we have a disabled person living in the neighborhood, we would be all too happy to have social services take care of him, instead of visiting him and checking on him personally. But there are studies that would argue against this claim. There are some new researches that came to the conclusion that with increased use of Internet and technologies, social contacts increased and social circle expanded for most people. "Because interpersonal communication dominates Internet use, using the Internet could have positive social…… [Read More]
South Florida, especially Broward County, has showed the most eagerness, with eighty seven percent in favor of solar energy investment. Central Florida and the Gulf Coast were close behind, and eighty percent of those living in North Florida also favored more state venture for solar energy. hile voters of all ages said they approved of spending more on solar, ninety three percent of those between eighteen and thirty four agreed. Statewide, the accord crossed party lines, with eighty two percent of Republicans favoring more public capital for solar energy, compared with eighty seven percent of Democrats. The poll also showed strong support for solar energy even if it led to an increase in utility bills. Overall, eighty one percent of those polled said they were willing to pay more each month on their utility bill to sustain solar energy (Poll: Support up for solar energy investment, 2008).

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. Jessa (2009) reminded us that "This understanding the atom helped to fuel many other…… [Read More]
Similar to Physical Science and Life Science, Earth Science will contain multiple choice and constructed response questions. A sample constructed response question from the Earth Science test is:
ased on the chart, explain various agricultural practices and how it affects the success of a yearly harvest.
This is a sample constructed response question. The student should carefully read and answer this question in essay form. Upon reading the question, the student should note that the question is requesting two separate answers
Praxis 7 because the question is a two-part question. Therefore, it is very important that the student reads the entire question and determine what information it is requesting before writing out his/her response. (Edge)
In conclusion, in most states, all students who wish to become teachers in the areas of Science or any other discipline will have to complete the Praxis test. The Praxis II test, code 0014…… [Read More]
Social Science and Why Is it Important?
The definition of social science has been narrowed down to those sciences that deal with human activities and human behavior as opposed to science that studies natural phenomenon. However this division may be superfluous now because modern science has its origin from the old social sciences. Science evolved from the society which also contained many thoughts that may be out of the realm of modern science like "religion, philosophy, ideology and politics." (Williams, 2000)
Thus the scientific theories are based on a philosophical thinking that is often shaped by politics or religion. The relationship between science and other streams of human thought and science changed with the changes in scientific method which again form within the disciplines of each branch of science is different and often contradictory. (Williams, 2000)
The argument at this stage is if the social world is amenable to experiments…… [Read More]
social science research are qualitative and quantitative research methods. Qualitative research is believed to operate from a subjective, constructionist view of reality, whereas quantitative research operates from an objective, positivist viewpoint of the world. There has been quite a bit of debate over the merits of each of these approaches, often with one paradigm belittling the assumptions of the other. The current literature review explores the philosophical foundations of each paradigm, compares their practical differences, and discusses the strengths and weakness of both approaches as they relate to research in the social sciences and to human resources research. The rationale for mixed-methods research, where the two paradigms are combined, is also discussed.
In recent years there has been substantial interest concerning the role of specific paradigms and philosophical assumptions with regards to doing research. There has been a growing concern regarding the adequacy of research methods in social sciences and…… [Read More]

Islam and Science
Islam and its Scientific Legacy
Many people are surprised when they learn of the tremendous debt modern science holds to Islam and the Arab world. Indeed, although most imagine the origins of science to be a Western phenomenon, arguably the greatest influences upon modern science today actually stem from the Islamic World.
During the height of the Middle Ages, the Islamic world was enjoying a tremendous high point of scientific, social, and academic learning. Great cities including Damascus, aghdad, Cairo and Moorish Cordoba were the epicenters of "civilization" as we now know it. Take, for example the great academic center that was Cordoba, the capital of then, Muslim Spain. Not only was it one of the first of the world's "universities," drawing students from around the globe, but it also was the home of the largest library in all of Europe. Moreover, the fact that the Cordoba…… [Read More]
Third Grade Science Instruction Plan
The Florida state standards for science education and knowledge achievements in the third grade essentially consist of background knowledge in all of the major branches of scientist inquiry and knowledge -- earth science, physical sciences, and life sciences (FDE 2010). This includes fundamental knowledge regarding the nature of matter and an introduction of types of matter, an understanding of energy and a knowledge of different objects that emit energy in the forms of heat and light and the basics of the energy life cycle amongst organisms on earth (FDE 2010). There are also numerous specific learning objectives identified in each of these and other areas of scientific knowledge that are defined by the state as necessary; the following lesson description touches on several of these areas (FDE 2010).

The relevance of physical security cannot be overstated when it comes to the prevention or minimization of instances of unauthorized access, loss, or even theft. In this text, I concern myself with physical security and the relevance of several of its components. The components I will address in this discussion are building security, grounds security, access control systems, perimeter security, and information systems and technology security.
Physical Security: Brief Overview
In the assessment of security vulnerabilities, physical security is generally regarded a critical issue. This is particularly the case given that it is the said physical security that presents the most serious obstacle to an attacker seeking to execute a break-in. In that regard therefore, the various components of physical security, some of which are discussed in significant detail in this text, should seek to secure people and organizational assets from intruders. For this reason, physical security could…… [Read More]
This occurred in 330 BC, and Zoroaster's date would then be 588 BC, and this date we may take to refer to the initial success of his prophetic mission which consisted in the conversion of King Visht-spa when Zoroaster was forty years old. Since he is traditionally said to have lived seventy-seven years, we will not be far wrong in dating him at 628-551 BC. It seems also to be generally agreed that the Prophet's sphere of operation in which his message was proclaimed was ancient Chorasmia -- an area comprising, perhaps, what is now Persian Khorasan, estern Afghanistan, and the Turkmen Republic of the U.S.S.R. (Zaehner, R.C., 1961, 33)."
Ayala's science takes the mitochondrial Eve back even before what we know about Zoroastrianism, but we really have no accurate date of the monotheistic tradition as it arises out of Zoroastrianism, because there are no written artifacts that support its…… [Read More]

Students in the 21st century have the opportunity to learn at a rapid pace, through the use of new media and new pedagogical methods. New media shifts the pedagogical focus away from fragmented knowledge towards a more integrative and multidisciplinary understanding of the natural world. 21st century learning engages students with material, encouraging them to think creatively and critically rather than simply learning by rote memorization. Science curricula in public schools should reflect the new tools and technologies of the 21st century.
The Australian science curricula remains committed to 21st century learning and the development of effective citizens. To develop effective citizens, science teachers need to cultivate in their students a sense of curiosity or scientific inquiry and an appreciation for the scientific method of answering questions. A scientific worldview encourages students to ask probing questions and shows them how to find the answers to those questions. Science is a…… [Read More]
Learning in theory and practice: Vygotsky’s ZPD and physical education in primary education
Age-graded schooling is one of the most common and conventional features of today’s academic environment. For younger learners in the primary education levels, this separation of young children from adolescents may seem on the face of it like a common sense approach to education—yet, as Gray and Feldman (2004) point out, separation such as this actually is more restrictive to the educative experience than it is facilitative. The reason is found in Vygotsky’s zone of proximal development (ZPD) theory. Vygotsky was an early 20th century Soviet thinker who articulated the idea that individuals learn most effectively when they are aided by other skilled individuals who know how to perform a certain task. Child learners can benefit, for example, from being placed in a zone of proximal development: alone or confined to a sphere in which they…… [Read More]
Bible & Depression
Depression is something that a lot of people suffer with in modern times and there is very much a tug-of-war between "modern science" and the Bible in terms of depression, how it should be dealt with and what actually makes things worse. The same can be said of the broader medical field as some people rely on faith alone rather than the "poison" and such of modern medicine. As with most things, neither extreme is wise and a middle ground that recognizes both science and faith should emerge. While it is possible to read too much into certain clips and phrases in the Bible, there are certainly portions and passages where depression certainly was pointed to or that almost certainly existed with or without mention.
The passages about Adam and Eve are a good starting point when it comes to depression and negative feelings. Indeed, Adam…… [Read More]
Attribution Theory and Emotional Intelligence
Attribution theory is a theory that focuses on creating an understanding of the ways in which people interpret events and the relationship of the events to their thinking and behaviors. The theory was proposed by Heider (1958), Weiner (1972 and 1986), and Weiner (1074). Attribution theory takes into assuption that individuals try to understand why people behave the way they do (attribute causes of events to behaviors). It also creates an understanding of behavior of individuals using three-stage processes that are considered to build the strength of the attribution. Among the processes include the fact that an individual should perceive or see their behavior, individuals should believe that their behaviors were due their intentional circumstances. Finally, individuals should determine whether they believe somebody else forced them to perform or engage in that behavior.
The relationship between these factors creates a web of causation…… [Read More]
Science is a “way of knowing,” meaning that it is one way of ascertaining the truth about the world. Although it is not the only way of knowing, it is the most reliable way of knowing the physical universe because it is based on systematic, rigorous methods of testing, experimentation, and calculated observations. According to the Union of Concerned Scientists (2017), science yields “unbiased and verifiable information to make important decisions,” (p. 1). The scientific method is used to acquire and analyze information. Using the scientific method, it is possible to test hypotheses again and again, to come up with verifiable and repeatable experiments that can yield factual and provable data.
The most important elements of the scientific method include observation, identification, description, investigation, and explanation. Observation is often the genesis of scientific inquiry. Observing an interesting, important, unique, or unusual phenomenon might lead to a hypothesis about why that…… [Read More]

Midterm Exam About Two Articles
Science is defined as the attainment of knowledge through practice or study. The concerted human effort in understanding better how the natural works using observable physical evidence is science (Chalmers p.4). There are many definitions of science and all point to one thing. Science involves making observations and studying in order to explain natural phenomena's. Without observation and study, it would not be possible to explain in a logical manner the various happenings that take place naturally. The interesting thing about science is the fact different theories can be formulated to explain the same phenomena. The hypothesis a scientist uses will determine the conclusions they make. Science is interesting because it offers people different explanations to why something happens and all the reasons could be logical or truthful. Having different meaning or theories explaining the same phenomena makes science a…… [Read More]

The selected sample chosen for this study belongs to the settings of people who do not belong to UK from their old generations and they are spending the lives of homelessness there. In other words, the paper is about physical and mental health of people who belong to other areas of the world but are settled in UK for education of job purpose. Since they are outsiders, they do not have permanent place to live in, they make temporal arrangements depending upon their requirements. Their priorities are different…… [Read More]
"Some Enemies of Science" J.B.S. Haldane
The vivisection debate: J.B.S. Haldane's "Some enemies of science"
The vivisection debate is an old one. As early as 1928, the scientist J.B.S. Haldane rigorously defended the practice of vivisection against its earliest detractors, arguing that even moderate government regulation of scientific behavior to protect animal rights was hypocritical, given the way that animals were treated in other spheres of human life. In contrast, David Suzuki's 1989 essay "The pain of animals" highlights the central paradox of animal experimentation. On one hand, animal experiments are only useful because of our biological similarities to animals. On the other hand, we assert our right to exploit animals based upon our inherent differences from them. The intelligence of animals such as the chimpanzee is analogous to a two-year-old child and yet through logical sleight of hand we justify using chimps in the laboratory by calling them…… [Read More]
eligion or Science?
Since the enaissance, there has been a vocal debate between religion and science. Galileo was imprisoned and sanctioned because of his views of the universe, the sun, and the way planets moved. As science progressed, this debate became even more heated. However, in the late 20th century, there has also been a mitigating discussion about the way that religion and science can actual coexist as explanations of the universe. In fact, as physicists look into the wondrous world of smaller and smaller particles, they find that the laws we through governed the universe do not really fit in with the abstract dimensions of time, space, quarks, and the study of the basic attributes of matter and the universe (Schroeder, 2010, p.xi ). On some level, the debate between science and religion is based on the notion of reason (the scientific method) versus faith. eason implies what can…… [Read More]

Human esponse to Physical Structure:
Environmental psychology is a branch of psychology that focuses on explaining human behavior in relation to the physical environment. In this case, the physical environment basically incorporates plants, animals, and material objects that have a significant impact on behavior at various levels. However, this branch of psychology does not focus on the interactional procedures among people as emphasized on other branches of psychology. In analyzing human behavior, it adopts a systems approach that has become the main approach in modern science.
Impact of Physical Structure on Human Behavior:
According to various theories, the physical environment or structure affects human behavior at various levels with instant behavior acting as a function of settings with which it happens (Matthew, n.d.). The individual personality traits of people within a specified country are largely influenced by the nature and type of physical environment that these individuals are subject to…… [Read More]
Wulf, S.J. (2000). "The skeptical life in Hume's political thought. Polity, 33(1), 77.
Wulf uses David Hume's well-known skepticism to advance his concerning the extreme degrees to which philosophy had been taken before returning to less radical modes. He develops material about the antithetical ideas to those investigated here; that is, he puts into a context the ideas of those philosophers who, working at the edge of the intelligible, refused to "accede to the judgment of reason and even their own senses."

Response to Karl Popper’s The Logic of Scientific Discovery
How the Reading Has Affected What I Believe about the Nature of Science and What It Can Tell Us about the World
Popper (2005) rejects the notion that inductive reasoning can lead to the identification of universals, and he uses the white swan as an example: “no matter how many instances of white swans we may have observed, this does not justify the conclusion that all swans are white” (p. 4)—no, and nor should it. However, one could legitimately analyze the swan still further, identify its species and thus conclude that this species of swan is always going to be white. White is one of the characteristics of this type of swan—so why should it not be viewed as a universal characteristic of this specific species? Popper’s approach to the nature of science is rooted in the empirical analysis—in deduction rather…… [Read More]
76). As automation increasingly assumes the more mundane and routine aspects of work of all types, Drucker was visionary in his assessment of how decisions would be made in the years to come. "In the future," said Drucker, "it was possible that all employment would be managerial in nature, and we would then have progressed from a society of labor to a society of management" (Witzel, p. 76). The first tasks of the manager, then, are to coordinate an organization's resources and provide a viable framework in which they can be used to produce goods and services effectively and efficiently. The second set of tasks concern guidance and control. In Drucker's view, this role is almost entirely proactive: "Economic forces set limits to what a manager can do. They create opportunities for management's action. But they do not by themselves dictate what a business is or what it does" (Drucker,…… [Read More]

It was originally established in the early 19th century by Auguste Comte who tried to unify history, psychology and economics through an understanding of society as a broad paradigm. Emile Durkheim took this a bit further and focused on the way societies could maintain a sort of integrity within the modern work where past cultural trends (religion, ethnicity, etc.) were no longer the singular part of society. His view, which has become the modern view of sociology, surrounded questions of what binds individuals together as a formal group (society) and what happens to this group both collectively and for the individual. This is a broad discipline as well, and clearly an academic response to the modern age (industrialization, urbanization, secularization, etc.). The field looks at social rules, the way those rules were formed, and the way that individuals coalesce into groups, communities, institutions, and even powerful social organizations that transcend…… [Read More]
Live Without Science?
The vast improvements in the quality of life modern humankind has been experiencing are due in large part to the developments and innovations in science. These are not only confined to one or two branches of science but all branches thereof have made significant contributions. Whether it is in the biological, physical, technological, medical or other science, each branch has provided breakthroughs that resulted in having a better life for each of us. For instance, "new technological advances lead to new scientific discoveries [such as] developing DNA copying and sequencing technologies [that] led to important breakthroughs (University of California Museum of Paleontology et al., 2011). Diseases that used to be dreaded in the past and caused several deaths are now curable because of our knowledge in DNA technology.

This process places the user in a central position for both determining system requirements and ensuring they are met.
The benefits of these systems include not only improvements in user efficiency, but also others, such as reduced training costs, reduced user errors, reduced maintenance costs, and increased customer satisfaction. However, the chief requirements in these kinds of systems become to understand the users' information needs. As we argued earlier, the systems analysts cannot determine information needs scientifically, rather the system analysts are required to obtain this needs by projecting an extrovert interpersonal style that fits more closely to an art form.
Design evaluations and maintenance are carried out with users of the systems (Smith and Dunckley, 2002). Although we believe that most of maintenance is routine, but in critical cases how systems are made usable so that users do not suffer their work requires an understanding of working around the…… [Read More]

As the road is being laid the fumes from the chemical materials and the concussive force of the construction equipment are devastating to local wildlife (Forman & Alexander, 1998). The result, is displaced organisms which ultimately put increased pressure for food, land, and water on other ecosystems. The extent of these ripple effects are still yet to be fully known.
In instances where above or below ground water supplies must be altered in order to make way for a new road system the effects are if anything more dire. When laying the bed of a road, it is nearly impossible to prevent a percentage of the chemicals used in the road surface itself from leeching into the soil (Forman & Deblinger, 2000). When in the presence of water those toxins are carried the course of the water supply affecting all of the vegetation and wildlife which it comes into contact…… [Read More]
At the same time, there is a different element introduced in the pursuit of forensic science that is not dealt with in other branches of scientific inquiry. As the question of justice is also central to any forensic proceeding, the suspect's account of events and/or hypothesized explanations for observations must also be taken account (Young 2009). In this way, both verification and falsification can be used during experimentation.
Before these experiments take place, however, the predictions must lay out a way to clearly identify the expectations of the experiments, as well as a way the methods by which they should be conducted. Several predictions can usually be made rather quickly after the hypothesis that are fully testable and easily determined. Based on hairs found at the crime scene, for instance, it could be predicted that skin found under the victim's fingernails was of the same DNA as the on-matching hairs…… [Read More]
There are exceptions, where legal ramifications are employed and individuals are held to account for their inaction. For most people, including myself the idea that faith is the only solution to medical concerns, and especially emergent ones is unfathomable. Medical care is congruent with faith, as even for the most ardent believer in God if God had not meant for children to be cured of preventable a treatable disease he would not have developed treatments to do so. For the broader population this is a reasonable tenet and most people report taking themselves and their children to a doctor or hospital when they feel it is necessary. It is also clear that modern people are even more involved in their own wellness and may even be able to treat some injuries and illnesses at home, without medical intervention. Furthermore most know when they need to seek care for themselves and…… [Read More]
Philosophy of Science
Scientific theories allow scientists to organize their observations regarding reality and existence, and predict or create future observations or results. Scientific theories need to be consistent, testable, verifiable and useful in order to be valid and reliable. Theories are typically ideas about the ways in which things work. Scientific theory relates to logical and empirical criteria that can be tested and validated. For science to exist and to be considered valid there must be a logically consistent idea presented to the public that explains certain conditions or realities. To be valid, science must explain something and should be proven via experimentation. Science should also enable the user to have a better understanding of the item or issue it is explaining. This relates to validity.

Often, bones have different shapes and/or sizes depending on whether they belonged to a male or female individual, and age also plays an important factor in the way bones look (Maples, 142). hereas doctors usually specialize in a certain branch of medicine, as in pediatrics or gerontology, forensic anthropologists must retain a broad range of knowledge because they might be called in to identify bones or other remains from any individual of any age or pathology. If they only knew a small portion of the type of details that could aid them in such identification, that particular forensic anthropologist's usefulness would be severely limited. Throughout his book, Dr. Maples demonstrates quite clearly how vital it is that observation, research, and learning continue throughout one's career as a forensic anthropologist, especially in the area of biology. As medical and biological knowledge grows, the forensic anthropologist must stay up-to-date or run the…… [Read More]
) Hydrochloric acid, formic acid, nitric acid, hexanes, and toluene are all available in ACS grade through Carolina, which, with a bit of imagination, could turn into some spectacular experiments. (Toluene is, of course, a component in the production of TNT -- talk about an exothermic reaction.)
Laboratory equipment is also widely available. A simple search of the popular site Shopwiki.com reveals hundreds of beakers, pipettes, test tubes, alcohol burners, syringes, etc. More advanced items are also available, such as hot plates which automatically stir the contents of a flask placed on them, and a wealth of thermodynamic devices for pressure, temperature, and volume control.

As such, a nurse is primarily to recognize herself as an individual in the world, with certain responses to this world. When a patient enters the hospital, such a patient is also to be seen as a unique individual who responds to the world and his or her environment in a certain way.
Humanistic nursing is then primarily experiential rather than experimental. This means that new knowledge is gained with every new patient that arrives for treatment. In giving treatment, responses are observed and noted for future reference in similar situations. It is not however assumed that a treatment will work because it did in the past and in similar conditions. Instead, hypotheses are based upon experiences of the past. The recognition that hypotheses may prove incorrect helps the nurse to be open to new experiences. Each human being is then seen as a "world," as it were, with the…… [Read More]
Physical vs. Digital Products -- Physical products are those that can be touched, felt, have physical presence, must be produced, warehoused, packaged, shipped and purchased. However, physical products are most certainly not limited to brick and mortar stores. The Internet has opened up an entirely new world for commerce online -- in both physical and virtual worlds with e-Commerce. E-Commerce is the buying and selling of products and services over electronic means, usually the Internet. As Internet usage grows, so does trade conducted electronically, allowing for a number of improvements and innovations that follow suit. Most economists see e-commerce as a market segment that leads to intensive price competition and consumers armed with greater knowledge. In two particular industries, e-commerce has actually changed the way the market works on those industries, causing the brick and mortar versions to fade away. In fact, larger e-commerce firms like Amazon.com, use…… [Read More]
A Balinese gamelan ensemble from Los Angeles comprised of half Western and half Balinese musicians took my breath away but to analyze the show proved to be the most difficult class assignment the entire semester.

Trying to wrap my head around the complex rhythmic structure and near lack of melody made my brain feel like it was melting more than any biochemistry class came close to doing.

Even a creative art like music demands…… [Read More]
Very often workers must choose jobs based upon benefits, not where they wish to work. orkers may decide not to open up small businesses or work for smaller businesses who cannot offer them comprehensive care. and, of course the children of uninsured workers suffer, innocent victims of the system.
Even companies like Safeway that have made heroic efforts to foster healthy living and disease prevention initiatives to cut costs have stated that universal health care is necessary to contain costs and keep their workers healthy enough to work, with as few sick days as possible.
