Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.

- no

Problem: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe.

Question: "What force causes pencils to roll off your desk and fall to the floor?"

Answer: "It's cylindrical shape"

Tokugawa Takes All: When Hideyoshi died in 1598, he hoped to have his five-year-old son continue his "dynasty," initially under the tutelage of five regents. But one of the regents was Ieyasu Tokugawa, who had been biding his time at Edo for 12 years, nurturing dynastic ambitions of his own. Of the cunning, ruthless triumvirate that came out on top at the end of the country's century of civil war, Tokugawa was without doubt the most patient, the most prudentand most treacherous. He moved quickly to eliminate his strongest rivals, crushing them in 1600 at the great Battle of Sekigahara (near modern Nagoya). During its subsequent two and a half centuries of rule from the new capital established at Edo, the Tokugawa organized a tightly controlled coalition of some 260 daimyo in strategic strongholds throughout the country. The allegiance of this highly privileged and prestigious group was ensured by cementing their ethical principles in the code of bushido, "The way of the warrior": loyalty to one's master, defense of one's status and honor, and fulfillment of all obligations. Loyalty was further enforced by holding the vassals' wives and children hostage in Edo. All roads into Edo, the most famous being the Tokaido Highway, had checkpoints for guns coming in and for wives going out. One of the most effective ways of keeping a tight rein on the country was to cut it off from the outside world, to keep Japan Japanese. At first, Ieyasu Tokugawa was eager to promote foreign trade. He wanted silk and encouraged the Dutch and British as good, nonproselytizing Protestants just interested in trade. But he didn't like the Portuguese and Spanish Catholic missionaries, who he felt were undermining traditional Japanese values. He banned their activities in 1612 and two years later ordered the expulsion of all missionaries and unrepentant Japanese converts. Executions and torture followed. Converts were forced to renounce their faith by trampling crucifixes and effigies of Jesus and Mary. The Catholic Church has counted 3,125 martyrs in Japan from 1597 (beginning under Hideyoshi) to 1660. In 1635 the Japanese were forbidden, on pain of death, to attempt to travel abroad, and Japanese citizens already overseas were prevented from returning, in case they brought back subversive Christian doctrines. Western books were banned, as were Chinese books that mentioned Christianity.
