TLDR
In this article, it was shown that on this point, although the result found is correct (to first order), the equivalence principle was in error and the Doppler effect was incorrect.Abstract:
EVER since Einstein introduced the equivalence principle and used it, in conjunction with the Doppler effect, to derive the gravitational redshift of spectral lines1, this argument has been an ingredient of many2–6 (though not all7–11) expositions of relativity theory. We show here that on this point Einstein was in error, although the result found is correct (to first order).read more

Sister-chromatid exchange induced by X-ray of human lymphocytes and the effect of L-cysteine.
TL;DR: Scoring SCEs may provide a useful technique for assaying the mutagenic effects of environmental carcinogens as well as the protective effects of antimutagenic agents.

Clarifying possible misconceptions in the foundations of general relativity
Harvey R. Brown,James Read +1 more
TL;DR: In this article, the authors discuss what they take to be three possible misconceptions in the foundations of general relativity, relating to: (a) the interpretation of the weak equivalence principle and the relationship between gravity and inertia; (b) the connection between gravitational redshift results and spacetime curvature; and (c) the ability to transform away gravity in local inertial coordinate systems.

TL;DR: In this article, the authors discuss what they take to be three possible misconceptions in the foundations of general relativity, relating to: (a) the interpretation of the weak equivalence principle and the relationship between gravity and inertia; (b) the connection between gravitational redshift results and spacetime curvature; and (c) the ability to "transform away" gravity in local inertial coordinate systems.

Gravitational redshift and the equivalence principle
P. T. Landsberg,N. T. Bishop +1 more
TL;DR: In this article, the equivalence principle leads to transformations between flat spacetimes, and a generalized Lorentz transformation is proposed which covers transformations from inertial to uniformly accelerated frames of reference.

Three Common Misconceptions in General Relativity
Harvey R. Brown,James Read +1 more
TL;DR: In this paper, the authors highlight and resolve what they take to be three common misconceptions in general relativity, relating to the interpretation of the weak equivalence principle and the relationship between gravity and inertia, and the connection between gravitational redshift results and spacetime curvature.

The theory of space, time and gravitation
TL;DR: In this article, a key input circuit is described where the key input signal is serialized and applied directly and through a circulating register working with a certain delay time to one gate for transmitting the direct input signal and to another gate to transmit the output of the register utilizing the other signal as an inhibitation signal.
