At the Poles, the Sun circles around the horizon forever. At the Equator, it rises vertically at the East point on the horizon, passes directly overhead, and then sets vertically at the West point on the horizon (Seligman). These same mechanics should apply for other solar and planetary systems as well.
As an example, the seasons on the other planets in our solar system compare to the seasons on the Earth. Planets, such as Mercury, Venus and Jupiter, which have a tilt near zero or 180 degrees, so that their axis of rotation is perpendicular to their orbit, have no seasons. Planets, such as Mars, Saturn and Neptune, which have a tilt similar to that of the Earth, have seasons similar to the Earth (although all three of those planets, being further from the Sun, have longer seasons, and colder ones, than the Earth). Planets, such as Uranus and Pluto,…… [Read More]

The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or collapse completely, forming black holes in the manner that stars much larger than ten solar masses, or ten times the mass of our sun
Generally, planets are defined as a body that emits no light or other energy of its own, but orbits a star, reflecting its light. A more technical definition of a planet relies on its size relative to the mass of Jupiter or "Mjup's." According to this description, a planet is larger than Pluto and…… [Read More]
life form found on Mars would be like. Mars is the fourth planet from the sun, while Earth is the third, so the planets are relatively close neighbors. However, the environments on these two planets are extremely diverse. Earth is a planet where life has evolved, while Mars is a barren planet devoid of life. However, if life could survive there, it would be extremely different from what we are used to here on Earth.
First of all, Mars has an atmosphere, like Earth does, but the Mars atmosphere is at least 100 times less dense than Earth's atmosphere. That means that the Martian atmosphere is not as protective as Earth's atmosphere, and that more of the sun's rays and radiation reach the planet. Mars does have enough atmosphere to create weather systems like clouds and winds, just like Earth, however (Squyres). Mars is colder than Earth because it is…… [Read More]
hile hard facts, such as Venus' circumference, diameter, and distance from the sun are relatively easy to determine, historical and future implications of the planet and its study are not as simple to calculate. Two of the most important facts that we don't yet know about the planet Venus are the significance of its historical positioning and its implications for earth's atmospheric problems.
According to Ev Cochrane's study into the ancient solar system, the regularity with which the system now moves around the sun is a "recent development." In the ancient world, instead, Cochrane suggests that observers noted a different type of solar system. The discrepancies between the two solar systems has largely to do with the planet Venus. According to Cochrane, Venus' movement into its current orbit was recent, and this movement created solar side effects that may be important to the current development of the solar system. hile…… [Read More]
Planet of the Apes is a very moving rendition of theme of brutality of slavery and the damaging consequences of the man's self-destruction. Particularly the last scene where the statue of liberty is shown is very heart rending and neatly depicts the height of mans madness who is the only creature on the planet to destroy himself. Unlike other science fiction movies this film is rich in social implications. Overall the movie is about the voyage of astronauts who travel in space exploring the cosmos. They end up on a strange planet inhabited by apes. The three astronauts think that they are some 300 light years away from earth but only later on in the last scene it is revealed that they are back on mother earth but to our utter shock and disbelief the planet is not the same anymore. Uncontrolled selfish warfare has led to the total destruction…… [Read More]
Planet of the apes series is one of the most successful series in American cinematic history. Product of the anti-Vietnam War sentiment, open racial tension, the War on Poverty, fear of nuclear war and lingering Cold War anti-USSR passions, the first 5 films in the series were also based on knowledge of and research about apes up to and including the 1960's and 1970's. Rise of the planet of the apes was released 38 years later and placed its emphasis squarely on apes as a valuable subject rather than a symbol.

eligious Life of Planet Earth
This report seeks to establish if planet Earth is a religious planet. In so doing, the report will primarily outline the criteria used to determine if the inhabitants of the planet are religious and the various beliefs and behaviors they exhibit in line with the criteria. Further, the report will also highlight the function of religion (as it appears to be) on the planet under consideration.
To establish whether or not Earth is indeed a religious planet, the very nature of religion on the planet must first be understood. This can be accomplished using a number of approaches. On of the most effective approaches in this case has got to do with evaluating the primary characteristics of religion. This is the criteria the report utilizes in an attempt to determine if the inhabitants of planet Earth are indeed religious.

The intent or purpose of this book was originally intended to be a science fiction written to meet a bet, but it ended up being the first book in a trilogy with the theme of describing how pitiful human beings are and how far from our original purpose on the earth - that is to tend it and make it plentiful, and to care for one another. C.S. Lewis was a Christian and this Christian theme permeates all of his novels. The theme of the book is that earth is seen by inhabitants of another planet as being valuable, but the humans are a problem when they think of inhabiting our planet. Oyarsa may be an angel and seems to care for the earth and sends Ransom back with a mission to make the earth better. This theme of bettering the planet Earth is the main one, plus Lewis has…… [Read More]
g. volcanoes, etc.), but not on schedule; 3) Just because something is plausible does not make it true. The events on popular television series like Star Trek or Star Wars are not only plausible, but have scientific merit. That does not make them true, only possible (Kraus, 2007; Cavelos, 2000); 4) Conspiracy theories abound in numerous genres and surrounding numerous events. Examination of Marshalls' prose and "science," while seemingly credible does try to sell a product and only hints and speculates at facts without peer-reviewed data sources (Yowcrooks, 2009). While positive in tone, it also appears that if one believes conspiracy theories, most of us have only 133 weeks to live; or simply turn the calendar to a new page?

Rise of the Planet of the Apes
The interaction of human beings and the natural world has always been one of conflict because of the inhumane way that people can behave. Animal have been used by human beings as pets, as entertainment, and in the course of scientific research. Fictional depictions of this interaction have reflected the nature of this relationship between man and animal. Some people value animal research as a means of curing human ailments and others decry it as animal cruelty. This is not a clear cut issue, but rather one of many different viewpoints. This document will show various attitudes toward these interactions; the positive aspects of animal testing, the negative attitudes towards testing, and finally how both these attitudes are fitted into the context of the film Rise of the Planet of the Apes, a film which shows exactly how society feels about this complicated…… [Read More]

Criteria Employed to Identify eligious Behavior
Based on what we already know about religion in other parts of the cosmos, we will consider the following criteria to be indicative of religiosity on Earth: (1) itualistic prayer; (2) Symbolic rules that have no apparent utility or function beyond symbolism; (3) Ceremonial sacrifices (Sagan, 2002). Previous experience suggests that most religions are theistic and that the hallmarks of theistic religiosity are rituals used to demonstrate, reinforce, and transmit traditions to successive generations; symbolic rules that have no functional purpose beyond their symbolic value; and sacrifices meant to appease or thank imaginary supreme beings (Armstrong, 2003). While there are other forms of religiosity that involve more complex spirituality than presumed direct relationships between "gods" and living beings or causal relationships between the pleadings of living beings and natural events, for the purpose of a preliminary investigation, the foregoing…… [Read More]
From the point-of-view of the variation and flexibility of the species such cultivated woody crops rank as no more than cornfields. While the tree farms are conveniently be stretched on the private lands, national forests those are considered priceless reservoirs of most of the biological diversity of the nation cannot expand so easily. The commercial logging is considered as the greatest danger for survival of the national forest system. The timber sales are growingly concealed beneath the post fire recovery and fire prevention missions, forest health initiatives and restoration programs. (Endangered Forests: Endangered Freedoms)

discovered solar system and how it works. Using this solar system as an example the writer develops a basis for a believable solar system in another area and describes its functions and actions.
The discovery of the new solar system is very exciting and the world is eager to explore its fundamentals and its possible future use. The world is going to organize a team of scientists that will explore the new solar system using carefully modulated steps with which to discover its workings and elements.
Phase one is going to be an attempt to discover its atmospheric elements. Much like this solar system has atmospheres that contribute to the ability for life to exist on earth, and possibly other planets it is suspected there are similar atmospheres in the newly discovered solar system. We are going to determine what the planets' atmospheres are comprised of and whether or not…… [Read More]
Worldwide Population Increase Affect Planet
The world population is a lucrative endeavor that has influential effects on the immediate environment. One of the changing or growing avenues of the planet is that of the enlargement of the human population. Initially, the human population was perceived as a small entity within a vast planet. Nonetheless, the human population has been on the increase over the past centuries. Many lucrative approaches and human activities are part of the changes that have occurred because of the increase in human population in the planet. The avenues of performance within the spectral and planetary stratifications account to the many steps that have been taken by human beings in the environment. The environment is a fragile structure and body that deserves equitable management and security. In order to foster equitable management of the environmental sustainability avenues, there is a need to have a long-range of performances…… [Read More]
eligion on Planet Earth
Based on careful observation of the beliefs and practices of people on earth, I can state that human beings are mostly religious people. There are five characteristics that define their religiosity. First, religious people function in groups. They share the same beliefs and perform the same activities as part of their religious activities. Within each group, there is a hierarchy of ranks and people but all people generally identify with the group as a whole.
The second religious characteristic of humans is faith. I have encountered people with different religions. But all of them have faith. Faith involves beliefs in a deity or deities and the existence of supernatural beings called angels and demons. Each religious group believes in it and the group generally agrees upon the fundamentals of faith. The fundamentals are believed to be sacred and are very important for the adherents. The fundamentals…… [Read More]
Religious Life on Planet Earth
hat does religion look like? To my alien culture, religion will take different forms. It will be seen through kindness, through humility, through love and altruism. In this paper, religion is not a dogma, it is not something that necessarily takes place in a building. Religion to my culture is a spirit, an act that inspires hope, a conflict that has been resolved. It is people helping each other in time of need.
Three examples of behaviors that meet the criteria are: a) affection shown between two people such as holding hands, hugging, looking deeply into each other's eyes, or kissing; b) a smile on the face of a person being served food by another; c) a person picking fresh vegetables from a garden and sharing it with others.

Pluto nicknamed as “puzzling planet” or “runaway planet” was discovered by Clyde Tombaugh, a young US astronomer at the Arizona Lowell Observatory in 1930[footnoteRef:1]. Pluto is the largest known “dwarf planet” and the ninth largest object direct orbiting the sun. It’s the coldest, smallest and most distant planet from the sun. Similar to other Kuiper belt objects, the landscape of Pluto is mainly rock and ice. Astronomers have remained puzzled with the origin of Pluto for centuries with earlier work suggesting that Pluto is a residual planetesimal. [1: Tombaugh, Clyde, and Patrick Moore. 1980. Out of the Darkness; The Planer Pluto. Harrisburg: Stackpole Book]
There are varied hypothesis on Pluto’s origin such as the possible knocking out of Pluto by Neptune’s largest moon Triton implying that Pluto didn’t possess a fully planetary status. The concept was later rejected as subsequent research established that there is no interaction of Neptune’s and Pluto’s…… [Read More]
brown dwarf with a satellite planet was recently discovered by NASA's Spitzer Space Telescope; the implications of the discovery are discussed in a recent NASA-published article entitled "Astronomers Discover Beginnings of 'Mini' Solar System," online at < http://www.nasa.gov/vision/universe/starsgalaxies/spitzer-020705.html>. Also known as "failed stars," brown dwarfs are dim and rarely host solar systems. Because of their relatively small mass they cannot ignite and produce star light. However, brown dwarfs are also known as "super planets" because they often exist alone in space and are larger than most known planets.
The content of the article relates to many interrelated areas of cosmology and astronomy. First, the news clarifies the definition of brown dwarfs, of which relatively little is known because they are rare and dim. Also, if a brown dwarf can host a satellite planet then miniature solar systems could exist throughout space. The discovery also teaches fundamental concepts of astronomy such…… [Read More]
" The answer is not yet known, as the matter is divisive, with some people disregarding the effects that their actions have on the environment while a few others struggle to have the whole world understand and fight for the planet's well-being.
All things considered, humans depend on the global ecosystem and its balance, and, as long as we want to provide the future generations with a healthy life in a healthy world, we have to help nature regain its former glory.
Ecosystems are yet another proof that nature is clever and that it can use a multitude of factors to create perfect environments. It is almost a miracle how ecosystems have worked together to create the present day world, where countless organisms live together and depend on each other.

The last major x-ray flare occurred in 2003 ("O'Dell). Most of the energy from an x-ray flare is absorbed by the earth's ionosphere ("O'Dell). Thus, a CME can be far more dangerous for human societies than an x-ray flare.
The first and most subtle observable phenomenon signaling an upcoming solar storm are known as coronal loops, which are "kinks in the magnetic flux form" forced to the surface of the sun due to a buildup of magnetic energy (O'Dell). Dark spots on the sun's surface then appear, usually in the "footprint" of the coronal loops ("O'Dell). The dark spots visibly signal the buildup of magnetism. NASA describes the phenomenon of solar flares as occurring in three stages: a precursor stage, an impulsive stage, and a decay stage. During the precursor stage, the release of magnetic energy is only triggered and leads to "soft x-ray emissions," ("What is a Solar Flare?").…… [Read More]
run out of planet," is an interesting piece which explores the idea that the Sports Utility Vehicle or SUV is something more than what the name implies. David Goewey's in-depth outlook takes into account the history and possible prejudice that the manufacturers and major distributors of these SUV's may have against our exponentially diverse culture. Goeway's purpose in his essay is to present to his reader's attention the propaganda that vehicle manufactures are "forcing" onto society. Obviously, all vehicles have their purpose; the SUV has qualities that will meet any terrain requirements, whether off road or the highway. Goeway's position on American Vehicles is thus that they are too large and bulky, and this paper will discuss this idea further. (You need a thesis at the end of this paragraph, especially a few words telling the reader what you will be focusing on in the paper.)
Goeway first focuses on…… [Read More]
The planet's major resources are continually threatened by industry and business. Among them, water has become such a priced commodity that finding areas with uncontaminated drinking water is slowly becoming a feat. How many people actually still trust to drink quality tap water without being cautious over it? That seems to be the premise of the documentary Gasland (2010), which focuses on the negative effects of siphoning gas through hydraulic fracturing on surrounding areas of the land. In Josh Fox's travels across the countryside, the testimony, evidence, and glaring supportive evidence seem clear enough that there are adverse effects. The companies, however, seem reluctant to do any further investigations.
Gasland's introduction brings the audience first to Fox's land, with a special focus on the history of his house and a greater focus on the beauty of the surroundings. He proceeds through the film by mentioning the letter from a…… [Read More]
Stop Global Warming
What can be done to combat global warming?
Global warming is a very serious threat that should be taken seriously by people everywhere. It is happening all around the world: ice caps are melting, environments are changing, and regions are suffering because of this atmosphere change, as Al Gore (2006) says. What is happening to the world because of carbon monoxide and because of air pollutions from factories is bad for the health of the planet and it is also bad for the health of people. This has been proven by research and the World Health Organization (WHO). WHO states that outdoor air pollution is not safe to breathe because it is "carcinogenic to humans" (p. 1). So if it is bad for people and bad for the planet, why does it continue to happen? That answer has received some attention on a global scale at the…… [Read More]

Nike is one of the best-known athletic companies in the world. It boasts many high-end prestige brands, including its running, basketball, and other types of athletic shoes which can be customized. Nike also offers premium sneakers such as its Jordans and Air Max, which have tremendous cache in terms of style. Nike's new brand of SNKS feature gold or artfully designed sneakers that are not functional for working out but are worn for fashion. Nike also offers fan apparel for a wide variety of major league sports teams. Much of Nike's clothing runs more than a hundred dollars per item.
The company also offers a few lower-cost items but for the most part, Nike has always been a premium brand. There are many cheaper sneakers available but people buy Nike either because of the social cache given to the brand or because they genuinely believe the quality is…… [Read More]
98). Tickner understands that men and women have been socialized to view "nurturing" as strictly a "feminine trait" and the "dominance of nature as masculine" -- and that the scientific tradition views nature as "something to be conquered and subjugated" (McNamara, p. 552).
Moreover, Tickner believes that care for the global environment must be seen as a "common human value" that men and women can and should respect; also, she asserts that environmental security goals cannot possibly be reached "as long as scholars and policy makers continue to divide the world according to gender stereotypes…" (McNamara, p. 552). In Mary Mellor's book, Feminism & Ecology, the author believes that it is essential for ecofeminists to critique "patriarchy" because women have "disproportionally born the brunt of environmental destruction" (Urbanik, 2001, p. 116). Still, "…getting the relations between humans right will not resolve the ecological imbalance because the source of much of…… [Read More]
The video displays the different people from different backgrounds and the food that they will consume within the one week ahead.

" We have reached a critical point in our society where interpretation is needed from not only the parents, but also from our government officials. There are too many young adults that are choosing to end their life because of cyber bulling.

It's sad that it takes many tragedies before anything is done to correct the occurring situation. Following the suicide of Tyler Clementi New Jersey Senate released an anti-bulling law. "The bill would require training for most teachers and other school employees on how to recognize bulling, and would mandate all districts form a "school safety team" to review complaints. School administrators who do not investigate and reported-bullying incidents would be disciplined, while harassment, intimidation and bullying would be upgraded to conduct that…… [Read More]
As Masciulli (n.d.) points out, "few consistently peaceful societies and cultures exist or have existed historically, and clearly none that has been a macro culture or civilization," (332). Human nature also has a clear tendency toward patterns of behavior that can incite antagonism or violence. Defensiveness, protectionism, predation, and self-preservation are innate behaviors rooted in animal instincts. Peacemaking and peacekeeping efforts worldwide can alleviate suffering and ameliorate the effects of violence, but even these well-meaning efforts do not constitute an overall shift in global consciousness. Therefore, it is unrealistic to expect global peace in this lifetime but it is becoming increasingly possible to envision a world that becomes more peaceful one generation at a time. Peace, if it is possible in this lifetime, depends on radical paradigm shifts.
The first step toward achieving peace is realizing that violence is a state of mind, and that state of mind can…… [Read More]
272). There were great changes taking place during that period in history, and not all of those changes had to do specifically with science. Some of them stemmed from science in other ways, and were encouraged to develop because they had a better framework during that time.
Philosophy during that time also had a "momentous transfer of allegiance from religion to science" (Tarnas, 1993; p. 272). That deeply affected how people felt about themselves and their world, and it changed the way many of them thought. Those who embraced science did so willingly, and those who embraced religion were also afforded that right. In other words, whether a person focused on science or religion, that person had a choice. Things were no longer all about the Church, and what the Church had always taught people. During that time in history, many people were afraid of the Church and thought that…… [Read More]
The inner core, meanwhile, has greater density, at 13, and temperature, at 6,650°C (or 12,000°F).
Compared against other planets in the solar system, the Earth contains just the appropriate amounts of gases, elements, and other properties that make human and other organism life possible.
Mercury, the planet closest to the Sun, has lesser mass and volume than the Earth, at a fraction of only 1/18. However, it is as dense as the Earth, although Mercury's surface is made up of more solid mass, specifically rough, porous, dark-colored rocks. Its atmosphere is made up of sodium and potassium, which accounts for the planet's density and very thin atmosphere. It was hypothesized that the core of Mercury is made up of liquid iron compound, as a result of the presence of magnetic field.
Venus, meanwhile, exhibits a unique characteristic for being the brightest and hottest planet in the sky, with the presence…… [Read More]
The materials that are collected in them are solids from the various gases (which cooled inside these clouds). The gravity from the sun pulled them closer towards each other. This contributed to the formation of the planets and asteroids. ("Summary," 2007) (Williams, 2010)
Once a star is finished developing, is when solar winds will blow rock and debris away from the sun. This forms the Kuiper Belt and Oort Clouds, which is where the smaller debris is collected near the orbit of the outer body planets. These are the remains of the rubble that was used to create the solar system billions of years ago.
However, there is an exception to this pattern. In research that was conducted on distant galaxies, scientists discovered that there are not large outer planets with asteroid belts (i.e. Jupiter). This led to theories that much warmer Jupiter like bodies could exist closer to these…… [Read More]
"Once every 248 Earth years, Pluto swings inside the orbit of Neptune. It stays there for twenty years. During those twenty years, Pluto is closer to the Sun than Neptune. During this period of time, like the other eight planets, Pluto's atmosphere undergoes a fundamental change in character, briefly developing an atmosphere. As methane and nitrogen frozen at the poles thaw. As it moves toward its farthest point from the Sun, Pluto's atmosphere freezes and falls back to the ground" (Dejoie & Truelove 2008).
These eccentricities further suggested that Pluto was really much more "like a new group of objects found in the outer solar system," called dwarf planets and not worthy of the status of the other eight (Inman, 2008, p.2). Still, many astronomers argued in favor of a more inclusive definition that would still retain Pluto's status as a planet. In fact, one radical proposal: "would have made…… [Read More]
That question doesn't affect the classification of planets in our Solar System, but will be relevant to some others" ("Pluto no longer a Planet," orld Science Homepage, 2006).
Even some scientists who disliked the definition, however, felt that it was fair to demote Pluto. "According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit," and Pluto is not simply small, and Pluto also does not dominate its neighborhood but its moon Charon, is very large in proportion to the former planet, as is about half the size of Pluto, "while all the true planets are far larger than their moons" (Inman, 2006) "In addition, bodies that dominate their neighborhoods, sweep up asteroids, comets, and other debris, clearing…… [Read More]
The observing vehicle was the Cassini spacecraft that was sent to look at Saturn and its moons. Specifically, these findings relate to Saturn's moon Titan, the only known body (including planets and moons) known to have standing liquid on its surface. Instead of water, Titan's bodies of water are full of hydrocarbons rich with methane and ethane. The study focused on substances apparently floating on the surface of the bodies of liquid on Titan and the study tried to ascertain what those substances were and what caused them to appear or disappear at any given time. The study used a combination of observations from the Cassini craft and some theorization was thrown in based on the telemetry and other results from the Cassini craft. Prior theories had stated that the bodies did not have floating ice. The Cassini crew has an extended chance to view the phenomena given the rather…… [Read More]
Objects in Space
Many objects move around in space that proves to be a threat to the planet earth and its components. There is a chance of collision in relation to the number of objects in the space thus the need to adopt and implement preventive or tracking measures towards minimization of the effects. One of the effects of the collision of the numerous objects moving in the space is death of the humanities in extreme circumstances. Luckily, for the development of human beings, space is empty. It is also essential to note there is critical information or knowledge on the locations of the large objects in the space. This makes the chances of DS1 hitting any object accidentally to be very slim. Despite this essence, there are small objects in the space that eludes the knowledge the humanity in relation to the exact location. This makes DS1 to be…… [Read More]
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]
Scientists accept that Jupiter is mainly composed of large quantities of hydrogen and helium. There is some consideration as to whether there is the presence of a solid rocky core that contains elements that are much heavier. The quick rotation of Jupiter pulls the planet into an oblate spheroid. This means that there is a bulging appearance about the planets equator. The outer atmosphere is divided into multiple bands at variant latitudes. Due to the movement of the planet and the location of these bands storms are produced where the bands converge with each other. As the boundaries of one band intersect with the boundaries of another closer band, the resulting interaction produces a hostile climate. The energy produced by the interaction is translated into storm like conditions. The most visible of these storms is the Great ed Spot. This storm was identified as early as the 17th century by…… [Read More]
Chemical Properties of the Universe
Astronomers hypothesize that about 5 million years ago, the Solar System was filled with a plethora of hot gases and dust, swirling around a hot core. They think that once the core approached about 1 million degrees, the physics and chemical properties caused the gases to coalesce, forming the sun. During this time, there were millions and millions of asteroids. As these asteroids collided with one other, some combined and as their mass increased, gravity pulled more and more particles and debris in, and the planetoids became larger and larger until the planets of the solar system were formed. This was a process known as accreation, and over hundreds of millions of years, the solar system formed -- the continual bombarding of asteroids changing the planets, forming the rings of Saturn, and the landscapes of others, including the moons -- which were just smaller planetoids…… [Read More]
What causes solar storms? Why should people nearly a hundred million miles away on Earth care so much about them? Massive explosions of electrified plasma from the sun are identified as Solar Storms but often they just cause a beautiful light show in the farthest points of the Northern and Southern Hemispheres. The reason why human beings need to understand and care about solar storms is that they have the potential to cause devastating effects on the planet Earth. Those effects include problems that may affect daily life such as knocking out satellites, blacking out power grids, and completely altering the atmosphere and climate. Scientists have gathered plenty of information over the years to explain Solar storms and have even built a system to protect the Earth's energy. However, the earth is still vulnerable to solar activity, much of which remains a mystery to science. Scientists are also…… [Read More]
Noncoding DNA, also known as "junk DNA" describes portions of the DNA sequence that do not appear to have any presentable use -- they do not encode for proteins, etc. In fact, in a most eukaryote cells, a rather large percentage of the total genome is noncoding DNA, but this varies between species. However, it is now a misnomer to call this material "junk," because the more sophisticated we become at biochemistry, we find that many do have subtle biological functions, including the transcriptional and translational regulation of certain protein-coding sequences. esearchers also belive that other noncoding sequences have a likely, but unconfirmed function, as an inference from high levels of inherited tratis and natural selection processes (Masters, 2005, 163-5).
esearchers know that the amount of genomic DNA varies widely between organisms, as does the proportion of coding and non-coding DNA within these genomes. For instance, 98% of the human…… [Read More]
Copernican revolution has a pivotal role in the establishment of the modern sciences. We are very much familiar with the fact that the human mind had always been fascinated greatly by the changes taking place around him almost constantly. Human observation and sense of argument and ability to be logical has made him the most intelligent and consequently most powerful species on the planet.
It is very comfortable to believe that Earth is located at the centre of the universe and other planets rotate around it because Earth itself does not seem or feel to be moving and there are only sun, moon and other planets appearing and disappearing at their exact timings. It is quite logical and unless and until something really revolutionary come forward to refute this believe, it looks quite reasonable to carry on believing the same idea (Kuhn, pp 187).
The most significant change…… [Read More]
Assignment 2-1 -- a- Radiation may be considered information from space; different types of information from different sources. These are: 1) Light as a wave and particle, 2) Electromagnetism, 3) Cosmic Rays and 4) Ultraviolet radiation.
Part 2-1-B- Light may be measured by telescopes; other space radiation by radio waves; x-ray machines may absorb cosmic and x-ray energy.
Part 2-1-C- Stars and Planets emit electromagnetic; Sun emits UV, Electromagnetic and light; light intensity, etc. Measuring radiation from objects tells us numerous things; age of object, comparative data between object, distance, intensity, level of danger, potential changes within object over time.
Part 2-1-D- Spectrographs, radio frequency detectors, x-ray machines.
Part 2-2-a -- an atom is the smallest unit of matter; ions are types of atoms in which the protons and electrons (parts of the atomic structure) are not equal. Ions can exist independently in solution, while atoms may or…… [Read More]
Metric ystem -- One of the reasons measurement can be complicated is that there is more than one system in use. Based on the Ancient Roman system, the metric system is based on powers of 10; which is called decimalization. The metric system has been the preferred European and scientific method of measuring sine the 18th century, but is not part of the International ystem of Units, which is also standardized. Because the metric system is based on powers of 10, units are easier to align. cientists use the metric system as a way to have a common measurement between countries and over time. cientists use notation that makes it easier to conceptualize distances much easier, particularly when these distances are large. Mathematical examples include:
If Mike needed a desk that was 5 feet by 4 feet wide, how many inches of trim would he need for the whole desk.…… [Read More]
In other industrialized countries, however, like Germany, Italy and Japan, the main concern of governments today is that not enough children are being born to even reach the level of the replacement rate. This is almost certainly a mistake since reduction of population should be the main goal in order to save the planet, and additional middle-class consumers in Western nations are the greatest burden on the environment.
Encouragement of voluntary euthanasia will be another method of reducing the excess population. Today many billions of dollars are spent on the last thirty days of life and 65% of physicians and nurses in one survey admitted that had provided unnecessary treatments for the terminally ill. That statistic was mentioned frequently in the debates over health care reform, with the implication that those dollars would be better spent on medical care for younger and healthier people at the start of their productive…… [Read More]
Electromagnetic waves are energy waves produced by the oscillation or acceleration of an electric charge. They include radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Their wavelengths in meters are: radio waves (0.1 to 1000), microwaves (1 x 10-3 ~ 1 x 10-1); infrared (7 x 10-7 ~1 x 10-3); visible light (4 x 10-7 ~ 7 x 10-7); ultraviolet rays (1 x 10-8 ~ 4 x 10-7); x-rays (1 x 10-11 ~ 1 x 10-8) and gamma rays (< 1 x 10-11).
Scientists have inferred that such great amounts of energy as produced by the Sun (4x1026 watts per second) can only be the result of nuclear fusion
If such energy were produced through the most efficient chemical reaction, the Sun would not last for more than a few thousand years. Evidence suggests that the lifespan of the Sun is in billions of years;…… [Read More]
7. It has been scientifically proven with men witnessing the shape of the earth as seen from the moon that the earth is not flat but spherical.
8. Medically it has been proven that smoking is the cause of many harmful diseases and is addictive. We can ask any person who is a smoker to quit it there and then and it will be observed that they cannot thus proving that smoking is addictive in nature.
9. Adding 12 to 13 is a simple mathematical formula and does not require rocket science to understand. One can simply use a calculator or even the digits of the fingers to add 12 and 13 to find out that it is 25 and not 26.
10. Winning a lottery is simply luck and probability. If you are lucky enough, your number will be chosen. The probability for a person to win is inversely…… [Read More]
There lies question on whether scientific knowledge is able to answer all the questions that relate to physical reality. For many years, people have wondered what the earth is composed of, leaving them wondering if the nature's secrets will one day be revealed (Grant 64). However, it is notable that since Galileo discovered the moon in 1608, there has been a remarkable move by his fellow scientists.
A lot of studies in science including the origin of the solar system, sonata of the stars, how matter changes to energy, and detailed works of an atom, among others has not fully exposed the science knowledge. However, the human culture seems to change with science. orldview patterns prove that complex systems studies by working from their smallest constituents meaning from bottom up. These paradigms also confirm that the laws of nature pounce from deep symmetry writs in to the basics…… [Read More]
The universe viewed through a telescope looked different, and this difference in itself played into the Protestant argument that received truths may be fallible. In fact, the notion of truth outside empirical evidence became unsteady:
For most thinkers in the decades following Galileo's observations with the telescope, the concern was not so much for the need of a new system of physics as it was for a new system of the world. Gone forever was the concept that the earth has a fixed spot in the center of the universe, for it was now conceived to be in motion…gone also was the comforting thought that the earth is unique (Cohen 79)
However, while the telescope was transforming ideas about the shape of the cosmos and the relationship between science and faith, the microscope essentially remained a toy through much of the early modern era. If anything, the revelation of the…… [Read More]
Earth's Climate System is a complex system that is influenced by many different factors. The manner in which the climate is maintained, and makes life on Earth possible, is a culmination of the atmospheric conditions and the Earth's energy balance that is determined primarily by energy introduced into the system as well as its ability to trap energy in the greenhouse layer. The Earth resides in the "Goldilocks Zone", or the habitable zone, which is believed to be the region around a star in which the right conditions for life can be sustained; recently scientist have been able to discover other planets that could also reside in such zones. (Zin, 2017).
The Earth's climate system provides an ideal habitat for life based on its relationship to the closest star, the sun, and its orbital patterns. The rotation of the earth, as well as the rotation of the moon, give the…… [Read More]
PLANET IS TO BECOME MORE PEACFUL IN MY LIFETIME -- HOW IS THIS MOST LIKELY TO COME ABOUT?
If the planet is to become more peaceful in my lifetime: How is this to come about?
Over the years, many types of solutions have been proposed to the problem of the constant state of war which has gripped humankind for so many years: solutions political, economic, and artistic in nature. All of these solutions to some degree have failed. This essay will briefly review some of these proposals and then suggest that these various solutions cannot be deployed in isolation. Peace must be brought about through a multifaceted effort, through both a shift in culture and creating supportive institutions that facilitate dialogue. To bring about world peace or at least to establish a more peaceful planet requires change at every level of society.
"When I was a young boy," writes Johan…… [Read More]
Search for Extraterrestrial Life: The Existence of Non-Human Intelligent Beings in Our Galaxy
The possibility of extraterrestrial life has always intrigued philosophers, scientists, theologians and even lay people for centuries. The fascinating question of whether there are other intelligent creatures in space, however, remains unsolved despite technological advancements in science particularly because thus far, there still lacks conclusive evidence. Motivations for the search for non-human life range from scientific and philosophical levels, technical and practical levels, to even the need to eliminate the loneliness of the human race in time and space. Scientists and astronomers remain committed to the search because the answer to this question has profound consequences: it will explain the nature and destiny of intelligent life on the universe, the culmination of evolution in different galaxies and provide more insight on the role of human beings on the universe, as well as what they are capable of…… [Read More]
(1) Discuss which of the interrelationships between the environmental spheres, in your experience, has had the biggest effect on human society, or vice versa. Give some examples.
The work of Manahan (2005) explains that there are four traditional environmental spheres including the hydrosphere, atmosphere, geosphere and the biosphere. It is related however, that a fifth sphere should be included and that is the anthrosphere, which consists of "the things humans make and do." (Manahan, 2005) The atmosphere is reported as a very thin layer compared to the size of Earth, with most atmospheric gases lying within a few kilometers of sea level. The atmosphere serves a vital protective function in that it absorbs highly energetic ultraviolet radiation from the sun that would kill living organisms exposed to it.
A specifically important aspect of the atmosphere is that the atmosphere serves a vital protective function in that it absorbs highly…… [Read More]
Had this false belief not been perpetuated it may very well be Kepler who directly formulated the laws of gravity well before the time of Newton.
Kepler's second law, which is commonly referred to as the law of equal areas describes the speed at which any given planet will move while orbiting the sun. In his understanding and derivation of mathematical models to understand this process, Kepler noted that planets moves fastest when it is closest to the sun and slowest when it is furthest from the sun. Again, this observation viewed through contemporary lenses makes the connection between the "hidden forces" of gravity as the evident driver, but Kepler concluded otherwise. He noted that if a line were drawn from the center of the planet to the center of the sun, such a line would sweep out the same area in equal period of time. His explanation for the…… [Read More]
Not surprising to see concerts by Dave Matthews, Green Day, and other top groups since Live Nation recently purchased Ticket Master.
A recent article in the LA Times reports that 48% of consumers are "eating out less often now than they did six months ago" (Hallock, 2009). John Self, a professor at Cal Poly Pomona in Los Angeles County, who has published a study of why restaurants fail, estimates that about 1,100 restaurants open in L.A. County annually; and among those, 24% close the first year and within three years 50% of those 1,100 have closed. But given the sluggish economy, Self asserts that up to 50% of new restaurants may be expected close in the first year, double the number that close in good economic times.
Data are not available as to how the recession has affected HRC, or Planet Hollywood, Johnny Rocket's or other theme-centered restaurants, but it…… [Read More]
Global Warming: Fact ather Than Fiction
The focus of this paper is on global warming and its causes. In the introduction phase, we have given a brief overview of the problem alongside a brief look at the details of the problem itself. It is mentioned here that how much change has actually recorded in the previous decades and what the future might hold on for the planet if the trend keeps on going as it is right now. It has also mentioned the consequences of rise in temperatures which can result in many different scenarios.
We then focused on the causes of the problem and again had a brief overview of it, the causes were divided into two main sections and proper emphasis was given on one of it in order to give the root cause of the phenomena. The discussion phase have a more in-depth look at the causes…… [Read More]
Selfless Actions and a Sustainable Future
There are many ways in which a person can get involved in selfless actions that can help the planet. One of these is to take public transportation (or carpool) instead of driving. There are certainly people who live in places where they cannot do this, or who have the types of jobs where this simply would not be realistic. However, for the most part people who live in urban areas are capable of using public transportation in their daily lives or carpooling with others on their way to work or other types of activities, including shopping. This helps the planet because it reduces the number of cars on the road. In turn, that reduces the level of emissions being placed into the air. With healthier air, not only can human beings breathe better but so can plants and animals. The entire ecosystem…… [Read More]
However, their theories, like the catastrophic predictions, lack real, hard, personal evidence. They may be right - but what if they are wrong and civilization does nothing to combat global warming and the other issues facing the Earth?
In conclusion, it seems that many of the people who are so convinced the Earth will survive on its own are ignoring many of the facts. The Earth's survival has depended on regeneration and re-growth in the past, and many species have been eliminated in global events of the past (think of the dinosaurs). During these historic events, man was a blip on the global landscape, or did not exist at all. Today, billions of humans populate the planet and pollute it in a wide variety of ways. The Earth has been able to survive natural events in the past because it was naturally able to regenerate. Today, man has altered the…… [Read More]
Climate change is also described as global warming, the unnatural or manmade cause of the planet’s increase in temperature. Climate change is physically caused by the release of greenhouse gases which get trapped in the atmosphere, in turn trapping heat from the sun on the planet (Meyer & Roser, 2006). Other pollutants can cause problems for the environment as well, such as toxins released into the water from chemical plants, or nuclear meltdowns that result in oceans being poisoned. These are also lumped in with climate change, since they also alter the environment. One of the biggest producers This paper will describe how climate change is occurring, how corporations are involved, and what some companies are doing to address it.
A Poore, Williams and Tracey (2000) note, sea levels are rising as a result of climate change. This occurs because the heat trapped on the planet by greenhouse gases leads…… [Read More]
