THE sixth-form scholar and the first-year university student are in these days well catered for in the matter of textbooks of physics. To be sure, these in general conform to a standard pattern which lends itself to a grasp of detailed facts classified in a traditional and natural manner ...
能源工学,是研究各种能源,并以为人们供给更经济安全的绿色可持续能源,并完善生活的品质和环境问题为目标的学问。因此,能源工学系是重点研究未来能源的学科。未来将会使用的代表性能源有:太阳光、太阳热、燃料电池、氢、二次电池、生物、地热等。 能源为了人类生活和经济活动,是必需的。在经济规模变大,能源消费激增的...

In the general theory of relativity the doctrine of space and time, or kinematics, no longer figures as a fundamental independent of the rest of physics. The geometrical behaviour of bodies and the motion of clocks rather depend on gravitational fields which in their turn are produced by matter...

Realization of equivariance It has long been established as one of the fundamental principles of physics that all physical quantities must transform equivariantly between reference frames. Formally, a mappingf: X → Yis equivariant for vector spacesXandYwith respect to groupGifDY(g)∘f =...

One of the main points regarding the general theory is its application in the field of physics. The general theory, proposed by Albert Einstein, revolutionized our understanding of gravity and the structure of the universe. It introduced the concept of spacetime curvature caused by massive objects,...
