Since electromagnetic waves travel AT the speed of light in a vacuum, it is sometimes difficult to separate SR from ‘classical electromagnetic theory’. Maxwell’s equations can be derived from quantum electrodynamics (QED) with special relativity.... Fluid viscosity: from Maxwell to string theory Dam T.

was found for the Einstein–Maxwell–Weyl equations for gravitational, electromagnetic, and massless two- component spinor fields [4]. Much attention has recently been attracted by various low-energy effective string and string gravity... Conventional electromagnetic theory based on Maxwell’s equations and quantum mechanics has been very successful in its applications to nu- merous problems in physics, and has sometimes manifested itself in an

Then, we regard pure F (R) gravity as well as F (R)-conformally invariant Maxwell theory to obtain exact solutions of the field equations with black hole interpretation. Finally, we investigate... the wave equation for electromagnetic waves follows from Maxwell’s equations. Maxwell’s equations govern all of electricity and magnetism, so it is no surprise that they yield the wave equation. In Section 8.3 we see how Maxwell’s equations constrain the form of the waves. There is more information contained in Maxwell’s equations than there is in the wave equation. In Section 8.4 we

On one hand, string theory reproduces the structure of di erential On one hand, string theory reproduces the structure of di erential forms in the low-energy equations valid for momentum much less than the string tension.... topological gravity in the presence of a linear electromagnetic Maxwell eld and a nonlinear elec-tromagnetic Born-Infeld eld. We show that the mentioned magnetic solutions have no curvature singularity and also no horizons, but we observe that there is a conic geometry with a related de cit angle. We obtain the metric function and de cit angle and consider their behavior. We show that the

Well iot turns out you can also compactify the four vector Maxwell equations into two tensor equations like so Here is a vector with four components, sometimes called the 4-current, and is a 4×4 matrix called the electromagnetic tensor.
- A non axisymmetric solutions of the combined Einstein and Maxwell equations with a string has been found by Linet [7]. The four-dimensional horizonless solutions of Einstein gravity have been explored in [8, 9]. These horizonless solutions ([8, 9]) have a conical geometry; they are everywhere flat except at the location of the line source. The spacetime can be obtained from the flat spacetime
- boundary equations implied by Maxwell's equations, and are expressed by Fresnel's equations which specify reflected and refracted field strengths relative to those of an incoming electromagnetic wave.
- String Theory, principally the Dirac-Born-Infeld action, noncommutative open string actions, Chern-Simons couplings on the brane, D-brane actions and the connections with the Maxwell electrodynamics, Maxwell's equations, B-field and gauge fields.
- quantum gravity as String Theory [3] and Loop Quantum Gravity [4] give rise to the same expression for black hole entropy-area relation given by celebrated Bekenstein-Hawking formula. New great interest in thermodynamics of black holes has been observed for the latter decade.
