Planet Earth is made up of four overlapping subsystems that contain all of world’s land masses, water sources, living organisms, and gases. These four subsystems are known as spheres. Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere),...

An extended object, such as a rod or sphere has a center of mass. A system of masses also has a center of mass. The center of mass of either the extended object or a system of masses is where the total mass of the system can be thought of being concentrated. Answer and Exp...
along with another area in which the biosphere interacts closely with one or more of the other earth systems: soil. Though soil is part of the geosphere, its production and maintenance is an achievement of all spheres. The role of the biosphere in this instance is particularly...
In consequence of this, in the higher spheres, and even in society, all was chaos, and although everyone was interested, no one could tell whether the native tribes really were becoming impoverished and ruined, or whether they were in a flourishing condition. The position of Alexey Alexandrov...
For one, the elements and formless spheres are alternatives and not presented as a consecutive series. In other words, these presentations do not concern a meditative sequence through which one should proceed or not. Moreover, the first part of the discourse shows the one who meditates in ...
《烧毁的诺顿》是T.S.艾略特的书长序列《四个四重奏》的开场诗。这首诗于1936年首次出版,《四个四重奏》作为一个整体于1943年以书籍形式出现。在《烧毁的诺顿》中,它的标题来自一个腐朽的英国乡村庄园,演讲者沉思了过去、现在和未来的交集——以及完全超越时间的想法,仿佛占据了“转动世界的静止点”。在五个部...

‘tokens’ are unprepossessing sub-jects. Typically they are very small clay objects, per-haps 1 to 5 cm in size, in a variety of geometric shapes.Spheres, discs, cones and cylinders are typical forms.These are enigmatic pieces at best, and not the kindof object that sets the average ...
