A paradox concerning rate of information

Explanation of Feynman’s paradox concerning low-pass filters

In Feynman’s lectures there is a remark about the limiting value of the impedance of an n-section ladder consisting of purely reactive elements (capacitances and inductances). The remark is that the limiting impedance z = limn→∞ zn has a positive real part. He notes that this is surprising since the real part of each zn is zero, therefore it is impossible for the limit to have a positive real p...

The information paradox

The incompatibility between gravity and quantum coherence represented by black holes should be solved by a consistent quantum theory that contains gravity as superstring theory. Despite many encouraging results in that sense, I question here the general feeling of a näıve resolution of the paradox. And indicate non trivial physical possibilities towards its solution that are suggested by string...

A Paradox Concerning the Energy of A Dipole in a Uniform External Field

where the position vector r is measured with respect to the center of the point dipole. The meaning of the delta function in eq. (3) is discussed, for example, in sec. 4.1 of [1]. An important contribution of Faraday and Maxwell to electrodynamics was their emphasis on the electromagnetic fields as primary physical concepts. A consequence is that the electrical energy of a system can be calcula...
