Zakariya Essabar, a Moroccan citizen, moved to Germany in February 1997 and to Hamburg in 1998, where he studied medical technology. Soon after moving to Hamburg, Essabar met Binalshibh and the others through a Turkish mosque. Essabar turned extremist fairly suddenly, probably in 1999, and reportedly pressured one acquaintance with physical force to become more religious, grow a beard, and compel his wife to convert to Islam. Essabar's parents were said to have made repeated but unsuccessful efforts to sway him from this lifestyle. Shortly before the 9/11 attacks, he would travel to Afghanistan to communicate the date for the attacks to the al Qaeda leadership. Mounir el Motassadeq, another Moroccan, came to Germany in 1993, moving to Hamburg two years later to study electrical engineering at theTechnical University. A witness has recalled Motassadeq saying that he would kill his entire family if his religious beliefs demanded it. One of Motassadeq's roommates recalls him referring to Hitler as a "good man" and organizing film sessions that included speeches by Bin Laden. Motassadeq would help conceal the Hamburg group's trip to Afghanistan in late 1999. Abdelghani Mzoudi, also a Moroccan, arrived in Germany in the summer of 1993, after completing university courses in physics and chemistry. Mzoudi studied in Dortmund, Bochum, and Muenster before moving to Hamburg in 1995. Mzoudi described himself as a weak Muslim when he was home in Morocco, but much more devout when he was back in Hamburg. In April 1996, Mzoudi and Motassadeq witnessed the execution of Atta's will. During the course of 1999, Atta and his group became ever more extreme and secretive, speaking only in Arabic to conceal the content of their conversations. 87 When the four core members of the Hamburg cell left Germany to journey to Afghanistan late that year, it seems unlikely that they already knew about the planes operation; no evidence connects them to al Qaeda before that time. Witnesses have attested, however, that their pronouncements reflected ample predisposition toward taking some action against the United States. In short, they fit the bill for Bin Laden, Atef, and KSM. Going to Afghanistan The available evidence indicates that in 1999, Atta, Binalshibh, Shehhi, and Jarrah decided to fight in Chechnya against the Russians.

The mighty fane, with its three massive towers, rises majestically over the red roofs of the town. Its most striking feature is the great Norman screen, running up without buttresses or projections to the parapet and hiding the bases of the square, richly decorated towers of the west front. The plain centre of the screen is the work of Remigius, the first bishop. The rest of it is relieved with rich arcading of Late Norman and Early English periods. The wooden spires which crowned the towers were removed in 1807. In 1192 Hugh of Avalon determined to rebuild the Norman building of Remigius, which an earthquake had shaken. To him we owe the choir and eastern transept. His successors completed the western transept and began the west end of the nave. So much money had to be spent in rebuilding the central tower, which fell in 1239, that the canons could not rebuild the nave entirely, but had to incorporate the Norman end by Remigius. Unfortunately the axis of the west front does not correspond to that of the nave, which is too wide for its height. The low vaulting is a serious defect in the choir built by St. Hugh, but of the superb beauty of the Angel Choir, which encloses his shrine, there can be no doubt. In its richness of sculpture it is one of the masterpieces of Gothic architecture in England. The interior of the cathedral is remarkable for the harmony of its style, which is Lancet-Gothic, and the dim lighting of the nave only adds to its impressiveness.

Question: "Who created the eastern transept?"

Response: "Hugh of Avalon"

A: yes

Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.
