Albanian was proved to be an Indo-European language in 1854 by the German philologist Franz Bopp. The Albanian language comprises its own branch of the Indo-European language family. Some scholars believe that Albanian derives from Illyrian while others claim that it derives from Daco-Thracian. (Illyrian and Daco-Thracian, however, might have been closely related languages; see Thraco-Illyrian.) Establishing longer relations, Albanian is often compared to Balto-Slavic on the one hand and Germanic on the other, both of which share a number of isoglosses with Albanian. Moreover, Albanian has undergone a vowel shift in which stressed, long o has fallen to a, much like in the former and opposite the latter. Likewise, Albanian has taken the old relative jos and innovatively used it exclusively to qualify adjectives, much in the way Balto-Slavic has used this word to provide the definite ending of adjectives. The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications, mainly of the Catholic region in the North, but also of the Orthodox in the South. The Protestant reforms invigorated hopes for the development of the local language and literary tradition when cleric Gjon Buzuku brought into the Albanian language the Catholic liturgy, trying to do for the Albanian language what Luther did for German.

What are some reasons for uses of the Albanian language?

Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh").

What other building was on the list of targets besides the U.S. Capitol, the Pentagon, and the World Trade Center?

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?
Is an arrow released from a bow an example of mechanical energy?
