Paradox of radiation of charged particles in a gravitational field electric field has an accompanying magnetic field, and the whole oscillating electromagnetic radiation field propagates independently of the accelerated charge, carrying away momentum and energy. The energy in the radiation is provided by the work that accelerates the charge. The theory of general relativity is built on the equivalence principle of gravitation and inertia. This principle states that it is impossible to distinguish through any local measurement whether one is in a gravitational field or being accelerated. An elevator out in deep space, far from any planet, could mimic a gravitational field to its occupants if it could be accelerated
A Tale of a Tub in the reception of Swift's work is that the narrator of the work is an extremist in every direction. Consequently, he can no more construct a sound allegory than he can finish his digressions without losing control (eventually confessing that he is insane). For a Church of England reader, the allegory of the brothers provides small comfort. Martin has a corrupted faith, one full of holes and still with ornaments on it. His only virtue is that he avoids the excesses of his brothers, but the original faith is lost to him. Readers of the "Tale" have picked up on
