It's the best physics example of the divergence at work: the divergence of a vector field describes the distribution of point sources that produce it, and for electric fields, those point sources are charges. Proceedings are now published (A) once or twice (B) each month and include original papers of important new research findings and interesting reviews that shed new light on a particular subject or field.Problem 1: Div, Curl, and Maxwell in Cylindrical Coordinates 6 points] Gaus' Law is one of Maxwell's four equations: -E-ρ /6, It relates the divergence of the electric field to the volume charge density p at any point in space. Obituary Notices were printed in Proceedings up to April 1932 but since then have appeared as a separate publication. In 1905 the bulk of Proceedings increased so much that it split into two series: Series A (papers on the Mathematical, Physical and Engineering sciences) and Series B, (Biological sciences). Included in the publication was the Anniversary meeting and reports.
By the 3rd volume the abstracts were arranged under the order in which the papers had been read at the meetings the report of each discussion meeting was headed by a brief account of the business which preceded the reading of the papers. This is particularly useful given their complicated coordinate transformation.Ī meeting of the Council on May 10th, 1832 resolved that abstracts of papers submitted for publication in the Philosophical Transactions from the year 1800 be published in Proceedings. It is shown that dipoles, electric dipoles, quadrupoles and electric quadrupoles can be defined without reference to a metric and in a coordinates-free manner. An example is given of another unusual feature: a quadrupole which is free of dipole terms in polar coordinates has dipole terms in Cartesian coordinates. It enables quadrupoles to be correctly defined in general relativity and to prescribe the equations of motion for a quadrupole in a coordinate system adapted to its motion and then transform them to the laboratory coordinates. This is significantly different from the familiar transformation rules for a dipole, where the components transform as tensors. Transformations involving integrals have not been seen before. Here the correct transformation rules are derived, which are particularly unusual as they involve second derivatives of the coordinate transformation and an integral. Despite being studied for over a century, the use of quadrupoles have been limited to Cartesian coordinates in flat space–time due to the incorrect transformation rules used to define them.
