QUES: Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

QUES: The Principals Committee had its first meeting on al Qaeda on September 4. On the day of the meeting, Clarke sent Rice an impassioned personal note. He criticized U.S. counterterrorism efforts past and present. The "real question" before the principals, he wrote, was "are we serious about dealing with the al Qida threat? Is al Qida a big deal? Decision makers should imagine themselves on a future day when the CSG has not succeeded in stopping al Qida attacks and hundreds of Americans lay dead in several countries, including the US," Clarke wrote. "What would those decision makers wish that they had done earlier? That future day could happen at any time." Clarke then turned to the Cole." The fact that the USS Cole was attacked during the last Administration does not absolve us of responding for the attack," he wrote. "Many in al Qida and the Taliban may have drawn the wrong lesson from the Cole: that they can kill Americans without there being a US response, without there being a price."

MY QUESTION: The real question' is 'is al Qida a big deal'. Who did Clarke expect to answer this?

QUES: On his return to Nuremberg in 1495, Durer opened his own workshop (being married was a requirement for this). Over the next five years his style increasingly integrated Italian influences into underlying Northern forms. Durer's father died in 1502, and his mother died in 1513. His best works in the first years of the workshop were his woodcut prints, mostly religious, but including secular scenes such as The Men's Bath House (ca. 1496). These were larger and more finely cut than the great majority of German woodcuts hitherto, and far more complex and balanced in composition. It is now thought unlikely that Durer cut any of the woodblocks himself; this task would have been performed by a specialist craftsman. However, his training in Wolgemut's studio, which made many carved and painted altarpieces and both designed and cut woodblocks for woodcut, evidently gave him great understanding of what the technique could be made to produce, and how to work with block cutters. Durer either drew his design directly onto the woodblock itself, or glued a paper drawing to the block. Either way, his drawings were destroyed during the cutting of the block.

MY QUESTION: Durer was able to create larger and more complex woodcuts relative to the majority of other German's because of Durer's experience working where?

QUES: For much of the world, the Algarve is synonymous with Portugal, yet the Portuguese will tell you the exact opposite: the region has little in common with the rest of the country. The southern stretch of coast is more reminiscent of a North African landscape than a European one. It has no cosmopolitan cities, like Lisbon and Porto, which are farther north. Most of Portugal is known for quaint towns, medieval castles, and grand palaces. The Algarve is more recognizable for impenetrable blocks of tourist apartments, hotels, and meticulously manicured golf courses. And beaches. Think Algarve and the mind pictures long, glorious stretches of golden sands, secluded coves framed by odd ochre-colored rock formations, and deep green waters. With about 160 km (100 miles) of coastline, Portugal's southern province is one of Europe's premier beach destinations. The occasionally chilly ocean is the Atlantic, but the Algarve has a sultry Mediterranean feel. Its consistent climate is the best in Portugal, and one of the kindest in the world: more than 250 days of sunshine a yearmore than almost any other international resort area. The moderating effect of the Gulf Stream produces a fresh springtime breeze throughout winter, and in late January and February, white almond blossoms blanket the fields. In summer the heat is intense but rarely unbearable, and regardless, beautiful beaches and innumerable pools are always just a dive away. Magnificent year-round weather has made the Algarve a huge destination for sporting vacations. Superb golf facilities aboundseveral with tees dramatically clinging to cliffs and fairways just skirting the edge of the oceanand horseback riding, tennis, big-game fishing, sailing, and windsurfing are immensely popular. Sports, beaches and hospitable weathernot to mention easily organized package vacationsare surely the reasons the Algarve receives as many visitors as the rest of Portugal in its entirety. But it's not just international tourists that descend on the Algarve; many Portuguese from Lisbon and elsewhere in the north have holiday homes and spend their summer vacations here. The coast is neatly divided into the rugged Barlavento to the west and the flat beauty of Sotavento to the east. West is where you'll find the famous orange cliffs and surreal eroded rock stacks.
