　　　Scholars and students have always been great travelers. The official case for “academic mobility” is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the areas of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the best teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold
　　Mobility of this kind meant also mobility of ideas, their moving across borders, their simultaneous  (同时发生的)impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one thinks that only eccentrics have no interest in being credited(相信) with a striking discovery, or a new technique. It must also have been comforting to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, faced by question, ridicule or neglect.
　　In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately available, and providing for the very rapid transmission of knowledge.
　　Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centres of learning, and a far greater number of scholars and students.
　　In addition one must recognize the very considerable increase of all kinds of subjects, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.

A three-year independent investigation into the September 11, 2001 attack on the Pentagon has yielded new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception."
A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon.
　  What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all.
　　From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons (架线塔).
　　Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear (齿轮) is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered (改变) and can not be fully trusted.
　　These crash photos and videos shown here clearly have been doctored (篡改) and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma.
