Reckendorf
Reckendorf is a village of 2000 (2012) in the Upper Franconian region of northern Bavaria. It has a documented history going back more than 1000 years. It is one of the few villages which retains its synagogue structure, which was recently purchased by the village and renovated to be a community center. Some elements of its Jewish heritage were preserved in the renovation. Jews were invited to settle in the village after the decimation of the population of the Thirty Years war.
Mega Man Anniversary Collection
Mega Man Anniversary Collection is a compilation video game for the Nintendo GameCube, Playstation 2, and Xbox. It was released on June 23, 2004 for the GameCube and Playstation 2, and on March 15, 2005 for the Xbox. It contains the first eight "Mega Man" games, as well as two spin-off fighting games in the series. It also contains extras such as original artwork and remixed music.
For the first six games, a "Navi Mode" is available. This allows players to get hints from helpers if they are in need of help. It also changes the look of the health and weapon meters, as well as the weapon screen, for the first three games.
Stephen Krashen
Stephen Krashen is a linguist and educational researcher. He is professor emeritus at the University of Southern California (USC). Krashen moved from the USC linguistics department to the School of Education in 1994. He is also an activist who works hard to support bilingual education.
Dr. Krashen has published more than 350 papers and books about second-language acquisition, bilingual education, and reading. He introduced several important ideas in the study of learning another language, including the acquisition-learning hypothesis, input hypothesis, monitor hypothesis, affective filter, and the natural order hypothesis. He started the Natural Approach to language learning and teaching with Tracy D. Terrell . More recently, Krashen promotes the use of "free voluntary reading" during second-language acquisition, which he says "is the most powerful tool we have in language education, first and second."
Krashen lives and works in California. Government plans for education there turned against bilingual education. Krashen said that this was a bad idea and responded with research that showed problems with he new policies. He also spoke publicly and wrote many letters to newspaper editors. In 1998, Krashen campaigned very hard against Proposition 227. Though he tried hard, the proposition passed and got rid of most bilingual education in California. Even though he lost, Krashen continues to work hard in support of bilingual education as other states try to get rid of it. His letters often appear in many newspapers. Krashen believes researchers should be more active to educate the public, especially about bilingual education.
Krashen holds a black belt in Tae Kwon Do, and was the winner of the 1978 Venice Beach Open Incline Press. He spent two years in Ethiopia teaching English and science with the Peace Corps.
Earth's magnetic field
The Earth’s magnetic field is the magnetic field that surrounds the Earth. It is sometimes called the "geomagnetic field".
The Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth. As the Earth spins the two parts of the core move at different speeds and this is thought to generate the magnetic field around the Earth as though it had a large bar magnet inside it.
The magnetic field creates magnetic poles that are near the geographical poles. A compass uses the geomagnetic field to find directions. Many migratory animals also use the field when they travel long distances each spring and fall.
The magnetic poles will trade places during a magnetic reversal.
The Earth’s geomagnetic field is created because of two things. The convective motions in the liquid conducting core inside the center of the Earth are important for making the magnetic field. When the convective motions occur with the electrical currents around the Earth, the magnetic field is created. The Earth’s rotation is what keeps the magnetic field up. The interaction between the convective motions and the electrical currents creates a dynamo effect.
The intensity of the magnetic field is greatest near the magnetic poles where it is vertical. The intensity of the field is weakest near the equator where it is horizontal. The magnetic field’s intensity is measured in gauss.
The magnetic field has decreased in strength through recent years. In the past twenty-two years, the field has decreased its strength 1.7%, on average. In some areas of the field, the strength has decreased up to 10%. The fast strength decrease of the field is a sign that the magnetic field might be reversing. The reversal might happen in the next few thousand years. It has been shown that the movement of the magnetic poles is related to the decreasing strength of the magnetic field.
A geomagnetic reversal is when the north magnetic pole and south magnetic pole trade places. This has happened a few times in the history of the Earth. The magnetic reversal happens after the strength of the field reaches zero. When the strength begins to increase again, it will increase in the opposite direction, causing a reversal of the magnetic poles. The time it takes the magnetic field to undergo a reversal is unknown, but can last up to ten thousand years.
The Earth’s magnetic reversals are recorded in rocks, especially in basalt. Scientists believed that the last geomagnetic reversal occurred 780,000 years ago.
The magnetosphere is created by the magnetic field. It is the area around the Earth that acts as a shield against the harmful particles in solar wind. The magnetosphere has many different layers and structures, and solar wind shapes each of these layers. The interaction of solar wind and the magnetosphere also causes the Northern and Southern Lights to appear. The magnetosphere is very important in protecting the Earth against solar storms which increase solar wind activity. Solar storms can cause geomagnetic storms which sometimes have serious affects on the Earth.
The areas in between the north and south magnetic poles are the magnetic field lines. These lines leave the Earth from the vertical point of the South and reenters through the vertical point of the North. These two vertical points are called magnetic dip poles. The magnetic dip poles are commonly referred to as the magnetic poles. The magnetic poles intersect the earth at two points. The north magnetic pole intersects the Earth at 78.3 N latitude and 100 W longitude. This places the north magnetic pole in the Arctic Circle. The south magnetic pole intersects the Earth at 78.3 S latitude and 142 E longitude. This places the south magnetic pole in Antarctica. The magnetic poles are also where the magnetic fields are the strongest.
Like other magnetic fields, the Earth's magnetic field has magnetic poles.
The North Magnetic Pole is the point on the surface of Earth's northern hemisphere where the planet's magnetic field points vertically downwards. There is only one place where this occurs, near to (but distinct from) the Geographic North Pole.
Its southern hemisphere counterpart is the South Magnetic Pole. Since the Earth's magnetic field is not exactly symmetrical, a line drawn from one to the other does not pass through the geometric centre of the Earth.
The North Magnetic Pole moves over time due to magnetic changes in the Earth's core. In 2001, it was near Ellesmere Island in northern Canada at . As of 2015, the pole is thought to have moved east beyond the Canadian Arctic territorial claim to .
The Earth's North and South Magnetic Poles are also known as Magnetic Dip Poles, referring to the vertical "dip" of the magnetic field lines at those points.
Animals which take long migrations may depend on the magnetic field for a guide.
