The Gravitational Red-Shift [PDF]
arXiv, 2004 Attention is drawn to the fact that the well-known expression for the red-shift of spectral lines due to a gravitational field may be derived with no recourse to the theory of general relativity. This raises grave doubts over the inclusion of the measurement of this gravitational red-shift in the list of crucial tests of the theory of general ...

Red-shifts and red herrings in geographical ecology [PDF]
Ecography, 2000 I draw attention to the need for ecologists to take spatial structure into account more seriously in hypothesis testing. If spatial autocorrelation is ignored, as it usually is, then analyses of ecological patterns in terms of environmental factors can produce very misleading results.

The infinite red-shift surfaces of the Kerr and Kerr-Newman solutions of the Einstein field equations [PDF]
arXiv, 2007 In contrast to the Schwarzschild solution, the infinite red-shift surfaces and null surfaces of the Kerr solution to the axially-symmetric Einstein field equations are distinct. Some three-dimensional depictions of these surfaces are presented here for observers following the time-like Killing vector of the Kerr and Kerr-Newman solutions.

Zeno-Gravity Correspondence: Zeno's Dichotomy Paradox and Gravitational red-shift near Event Horizon [PDF]
arXiv, 2016 We relate Zeno's Dichotomy paradox with gravitational red-shift near event horizon in a spherically symmetric space-time. A dictionary of this connection, henceforth called as Zeno-Gravity correspondence, has been built up. The infinite sequence of Zeno's paradox gets mapped to the effect of infinite gravitational red-shift near event horizon and the ...

Infra-Red Frequency Shifts [PDF]
Nature, 1960 THE effect of liquefaction and solution in different solvents on infra-red group frequencies has previously been considered in terms of changes in dielectric constant and postulated local association effects (for example, Caldow and Thompson1, and Bellamy and Williams2).

On the Interpretation of Spectral Red-Shift in Astrophysics: A Survey of Red-Shift Mechanisms - II [PDF]
arXiv, 2018 This paper gives a compilation of physical mechanisms which have been proposed to explain the spectral red-shift of distant astronomical objects. Over sixty selected mechanisms are listed for the purpose of quantitative comparisons. Some of these mechanisms may not completely account for all astrophysical observations but are relevant to particular ...

Pink illusions and white shifts [PDF]
i-PerceptionA rotating stimulus of alternating red and white sectors generates a faint pink fill throughout the image. The trailing cyan after images of the red sectors quickly become the brightest regions in the image, providing an index of the overall illumination

Large shift in symbiont assemblage in the invasive red turpentine beetle. [PDF]
PLoS ONE, 2013 Changes in symbiont assemblages can affect the success and impact of invasive species, and may provide knowledge regarding the invasion histories of their vectors. Bark beetle symbioses are ideal systems to study changes in symbiont assemblages resulting
