The Weyl-Dirac theory of gravitation and electromagnetism is modified by the introduction of a background metric characterized by a scale constant related to the size of the universe. One is led to a natural gauge giving [(G)\\dot] \\mathord/\\vphantom [(G)\\dot] G G = - 5.5 脳...

The proportionality constant G is called the constant of gravitation, or gravitational constant. The first measurement of G was made in 1798 by the English physicist H. Cavendish, who used a torsion balance to determine the forces of attraction between spherical masses. According to the most ...

space associated with a spacetime point in the manifold, instead of the coordinate basis. These vielbein fields form an orthonormal basis of the tangent space at each point in the manifold with spacetime coordinatesx^{M}. The relation between the spacetime metric and the veilbein fields is ...
2, we first calculated the number of POIs and their diversity based on business types using Shannon Entropy (Shannon, 1948) for each district. This entropy metric measures the number of permutations of the states of a system. Here, it represents the number of different combinations of various ...
discuss the relation between our results and the observations. We conclude in Sec. 6 with a short summary of our results. 2. Model description 2.1. Model assumptions We use the Kerr metric to represent space-time curved by an uncharged rotating black hole. In Kerr geometry, the black hole...
