91Ginzburg–Landau theory — In physics, Ginzburg–Landau theory is a mathematical theory used to model superconductivity. It does not purport to explain the microscopic mechanisms giving rise to superconductivity. Instead, it examines the macroscopic properties of a… …
92Darwin Lagrangian — The Darwin Lagrangian (named after Charles Galton Darwin, grandson of the biologist) describes the interaction to order between two charged particles in a vacuum and is given by[1] where the free particle Lagrangian is …
93Dirac bracket — The Dirac bracket is a generalization of the Poisson bracket developed by Paul Dirac to correctly treat systems with second class constraints in Hamiltonian mechanics and canonical quantization. It is an important part of Dirac s development of… …
94Non-Radiative Dielectric waveguide (NRD) — Figure 1 Contents 1 Introduction 2 The dispersion relation in the NRD wave …
95Hole argument — In general relativity, the hole argument is a paradox which much troubled Albert Einstein on the road to his famous field equation. It has recently been reinterpreted by philosophers as an argument against manifold substantialism , a doctrine… …
96Charge conservation — In physics, charge conservation is the principle that electric charge can neither be created nor destroyed. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always… …
97Dirac string — In physics, a Dirac string is a fictitious one dimensional curve in space, conceived of by the physicist Paul Dirac, stretching between two Dirac magnetic monopoles with opposite magnetic charges, or from one magnetic monopole out to infinity.… …
98Liénard-Wiechert Potentials — The Liénard Wiechert potential describes the electromagnetic effect of a moving electric charge. Built directly from Maxwell s equations, this potential describes the complete, relativistically correct, time varying electromagnetic field for a… …
99Derivation of self inductance — The mutual inductance by circuit i on circuit j is given by the double integral Neumann formula Contents 1 Derivation 2 Self inductance …
100Electromagnetic shielding — cages inside a disassembled mobile phone. Electromagnetic shielding is the process of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive and/or magnetic materials. Shielding is typically applied… …
