Therefore, it is uncertain what causes Uranus' magnetic fields. Furthermore, "Uranus' magnetic field is odd in that it is not centered on the center of the planet and is tilted almost 60 degrees with respect to the axis of rotation. It is probably generated by motion at relatively shallow depths within Uranus." (Arnett, 2004).
Like the other gas planets, Uranus has rings." (Arnett, 2004). Nine of Uranus' rings were discovered in 1977. However, Uranus' rings differ from those found surrounding both Jupiter and Saturn. "The outermost epsilon ring is composed mostly of ice boulders several feet across. A very tenuous distribution of fine dust also seems to be spread throughout the ring system." (Hamilton, 2003). In addition, there are several narrow or incomplete rings that surround Uranus. Uranus' rings "are composed of fairly large particles ranging up to 10 meters in diameter in addition to fine dust. Uranus' rings were…… [Read More]
Interestingly, Venus is a goddess of love, beauty, and fertility, which is significant, since she was literally created from the male genitalia, and males were more strongly linked to sexuality than females, even at that point in oman history. In the rest of oman and Greek mythology, Venus/Aphrodite generally plays a benevolent role, though she does use influence women to use their sexuality in inappropriate ways, such as the willful seduction of one's own father.
Botticelli's painting captures all of the prettier elements of the birth of Venus without referencing the uglier parts of the myth. There are no castrated gods or vengeful sons in the painting, merely a beautiful, naked woman emerging from the sea, standing grown in a sea shell. The sea shell symbolized the vulva in art of that time period. Moreover, Venus was a frequent non-religious subject of paintings, because it was considered acceptable to depict…… [Read More]
Marriage in Greek Myth
efore we discuss the depictions of marriage in the Theogony, the Homeric Hymn to Demeter and the Odyssey, perhaps we should first discuss the real- life ancient Greek marriage rituals and reveal their attitude towards marriage.
Indeed, many of the things we see in Greek myths happened in real life as well. For example, the Greek girls usually married quite young, around the age of 14, which was meant to ensure that the girl was a virgin and pure in mind and body. "Marriage to a family member was an acceptable alternative and occasionally encouraged in order to consolidate family wealth"- if we look at many of the marriages between gods (taking only this example), we will notice that many of them were affiliated. Remember, for example, that almost all of the Olympian Gods were in some way related, most of them being brothers and sisters,…… [Read More]
In asking him to stay with her and their family, she was practically betraying her country. Demeter cares for the earth in a way that no other gods did. She was actively involved with mortal affairs. However, she also cared for own, her daughter. She does what she feels what she must do in an act of revenge. These women demonstrate the complexity of the female in any era. Even in ancient texts, we see the female figure associated with the typical womanly things such as motherhood and fertility but she is also given characteristics that are strong, powerful, and dangerous. What these myths tell us about the role of the female is that it is constantly changing. The female is complex and while she will always associated with fertility, she should never be relegated to an inferior role. While we often see mythology as wild with fantastical elements, we…… [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]
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]
The greenhouse effect is a condition that occurs when the Earth's atmosphere captures radiation from the Sun. Solar heat is trapped by certain gases (including carbon dioxide and methane). These gases allow sunlight in but not back out of the atmosphere. This effect can be seen on a small scale when a car parked in the sun with its windows closed heats up. Global warming is the relatively gradual increase in Earth's surface temperature that results from human activity. It has been set in motion by the greenhouse effect but is more complicated because there are feedback effects involved in climate change that magnify the initial effect of the build-up of gases such as carbon dioxide.
Global warming has the capacity -- indeed, probably the inevitable capacity -- of transforming nearly every aspect of our lives, and in most ways for the worse (Solomon etal, 2009, p. 1706).

In his attempt to paint the goddess, the Renaissance painter inspired from the mythological legend of Venus's birth. The Roman Goddess of love apparently emerged out of the sea as a result of a foam formed around Uranus's genitals that had just been cut by his son, Cronus. Cronus apparently did so in order to get revenge, since his father treated him very cruelly (Deimling 52).
otticelli focused on emphasizing the painting's contours with a black stripe, making them contrast the rest of the picture. This concomitantly makes the painting clearer and gives it a detached character. The flowers falling from the sky were also taken from the legend, since flowers and spring are associated to Venus's birth (Deimling 52).
Whereas the painting's title refers to the actual birth of the goddess, the painting itself seems to represent something else. Instead of showing Venus as she comes into this world,…… [Read More]
These are the best that Germany and the Soviet Union have at the same time and, while this is a known fact in most other history books for Germany, the authors of "When Titans Clashed" show better the importance of great generals for the final victory of Soviet Union as well. A new generation of generals, replacing the ones that had died in the purges of the 1930s, show their talents in all the battles of the Eastern front and, subsequently, in the conquest of erlin. The general acceptance is that these generals could have had even greater success had they not been caught in a political game, where the Commander in Chief, Stalin, was always aware of potential successes that could impact his authority.
The general opinion that the authors seem to share and promote in the book seems to rely on the main idea that, while the Western…… [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?

"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]
The scientists in the documentary the Great Global Warming Swindle (2007) are conservatives and are letting their politics rule their science. Even though they allege that the bad science in an Inconvenient Truth is unsupported by scientific fact, and just because they present scientific facts disputing the science presented in an Inconvenient Truth, just goes to show that the truth is not always convenient! Science has been wrong many times in the past, and everyday in the news there is information to show that what many of us grew up believing, like that Uranus is a planet; has been proven wrong.
Just because Al Gore did not use mathematical formulas in his an Inconvenient Truth, does not mean that the scientists who used mathematical formulas to show that Al
Gore's assertions were wrong are right.
Al Gore wasn't just vice president; he was also a United States senator and very…… [Read More]
Although they are verbal in nature, the striking image of many mnemonics, like MataHari the spy, or a mother delivering nine pizzas makes them effective.
Another mnemonic technique is to create a word called an acronym, a word that represents what needs to be remembered (Keeley 1999). Some acronyms, like Radar, or NASA, have become so popular and are used to frequently they have replaced the words they were created to encourage people to remember. An example of this would be to remember the Seven onders of the Ancient orld along the lines of 'MC SLAG': M (the Mausoleum) C (Colossus of Rhodes) S (Statue of Zeus) L (Lighthouse of Alexandria) a (Temple of Artemis) G (Hanging Gardens).
Acronyms can be effective if they sound funny, even if MC SLAG is unlikely to replace the actual list of the beautiful seven wonders! However, the planets might be more difficult, because…… [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]
Of course, this is a supreme being who was authorized by a greater power to represent law, order, equity and custom and was not only the wife of Zeus, but also his counselor. In pre-Hellenic times wiser women made the most important decisions. Perhaps a woman brings more balance into life, in every person. In ancient times, women had the best judgmental capacity and were the most important in taking decisions.
It is universally acknowledged that the earliest appearance of justice in ancient Greek civilization is as a Goddess, whose function is to judge humans by punishing or rewarding their conduct in relation to the Divine Principle. The oldest record of justice dating from ancient Greece is to be found in Homer's Iliad and Odyssey, where Themis is mentioned for the first time, being depicted as the personification of the social and moral order of human affairs. Mention should also…… [Read More]
e., their individuality and permanence, are the basic reason behind their having supplanted other previous methods of personal identification and explain the fact that fingerprints continue to hold their own against other more modern methods of identification such as DNA testing.
Individuality of Fingerprints
In more than 100 years since fingerprint records of individuals started to be collected and compared, no two fingerprints of two different persons, including those of identical twins, have ever been found to be exactly the same. This is not only true for the ridge patterns found on the fingerprints of individuals but also of the patterns on their palms and the soles of their feet. ("The History of..." 2006) ecent studies comparing the fingerprints of cloned monkeys showed that even they have completely different fingerprints. After the introduction of AFIS (Automated Fingerprint Identification Systems), it has become possible to compare the millions of fingerprints data…… [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]
Greek History World Civilizations
What made the Greek civilization so great? What made the Greeks so great?
Greeks are the most famous and advance people around the world. There are so many areas and variety of things that makes this country and nation so rich and lively. The Greeks has a great history due to having great philosophers, socialist, wars, kings, food, outfits, culture, and great thinkers.
The history of Greek civilization is very rich and deep, it can be dated back to 300 B.C. The nation is entirely long and vast.
It was the first civilization in Europe. This part of the world was developed near the eastern side of the Mediterranean Sea. It is also considered as the birthplace of democracy as per several popular scholars, nations and authors of the world in the history.
The Greek is the first democratic country over the earth. The idea of…… [Read More]
Billy Collins' poem is a lyric poem because mainly it expresses highly personal emotions and feelings. Many lyric poems involve musical themes or tones, and in fact in Shakespeare's era the word "lyric" meant that the poem was accompanied by a musical instrument (a lyre). But while Collins' poem doesn't give off a musical idea or theme (unless the sound of a fork scratching across a granite table is music), it does use metaphor and achieves a dramatic impact.
The metaphor has two people, presumably married and in a love partnership who have divorced. (It is known that although un-married couples who have been together for a long time and break up are also involved essentially in a "divorce" of their partnership.) The metaphor of "two spoons" shows two people locked together, snuggling would be a good word, in a warm bed. "Tined" means prongs on a fork -- or…… [Read More]
Aphrodite was said to have been the most beautiful and sensual of all the goddesses. There are varying stories of her birth. One story holds that she was born from the loins of Uranus, when his sex was severed from him and thrown into the sea: Aphrodite emerged from the sea foam—a daughter of the sea, which is why one of the most famous images of her in artistic expression is of the goddess emerging from the sea (Graves). Homer in the Iliad indicated that Aphrodite was the daughter of Zeus and Dione. Regardless of her origin story, Aphrodite served a central role in the back story of Greece, particularly when it came to her feud with Hera and Athena over who was the most beautiful of all.
Aphrodite was said to have married Hephaestus, the god of blacksmithing. She was also said to have had many paramours,…… [Read More]
