Description : a synthesized poetic & calligraphic exhibition, using the curvature appearance and the combinational construction of words with the help of spatial installations to present poetry in divinatory symbols and the scenes of space - time variations
簡述:綜合書法以線條、造形、文字結構以及空間實物藉以表現詩的易象與時空變化場景。 -
The casimir energy can be considered as the polarization of the vacuum energy of quantized fields due to the distortion caused by the presence of boundaries, curvature of the space - time manifold or some background fields
Casimir能量本質上是由於邊界的出現、時空的彎曲或是某些背景場的存在而引起的量子場真空能量。 -
Also, general relativity defines non - inertia space - time as a space of riemann. for riemann space has positive curvature, we have to doubt about where the minus curvature space is
廣義相對論把非慣性時空定義為黎曼空間,但由於黎曼幾何是正曲率空間,既然廣義時空是對稱的,我們必然要問,負曲率空間到哪去了? -
Abstract : with adopting of a frame of the principal fibre bundle. the article constructs a unified model of gravity and electromagnetic with torsion both in internal sp ace and in four - demensional space - time. the curvature on the bunde is calcula ted using connection theory in the principle fibre bundle. the action is construc tod with the curvature. the field equations are achieved. finally a discussion is made
文摘:應用纖維叢理論,在內部空間和四維時空引入撓率,建立了引力與電磁場的統一模型.利用纖維叢聯絡論求出主叢的標曲率,由它構造作用量,求得場方程,最後作一些討論 -
How the universe evolves is affected by three factors, namely the mean density of mass - energy, the space - time curvature and a mysterious factor, the cosmological constant
宇宙尺度的變化受三個因素影響:宇宙中質量-能量的平均密度宇宙的時空曲率與及一個神秘因素宇宙常數。 -
The future of the universe is mainly determined by the mean density of mass - energy and the space - time curvature, while cosmological constant does not carry any weight among popular cosmological theories
現在流行的宇宙論都不考慮宇宙常數,宇宙的未來完全由質量能量的平均密度及宇宙的時空曲率來決定。 -
Without space - time curvature, there is no meaning to general relativity, ie., classical gravity. without classical gravity, what is the meaning of quantizing it
或許在一個時空彎曲不再是必須條件的情況下,能夠成功的將引力量子化。
