Spectral sensitivity of the circadian system

The discovery of a novel photoreceptor in the retina that participates in circadian phototransduction (how the retina converts light signals into neural signals) has opened up a new area of investigation. It is still not known whether human circadian phototransduction uses mechanisms similar to color vision, i.e., opponent mechanisms at a post-receptoral level. The primary goal of the study reporter here was to answer the question: does the circadian system respond to light in an additive manner, or is a spectral opponent mechanism also involved? A secondary goal of this work was to determine if the spectral sensitivity of nocturnal melatonin changes throughout the night. The findings in this book are a first step toward a better understanding of the mechanisms underlying circadian phototransduction in humans. The present results demonstrate that an opponent mechanism contributes to the spectral sensitivity to light for human melatonin suppression. In general, retinal stimulation of humans from monochromatic, or nearly monochromatic, light sources might result in data that cannot be generalized to polychromatic sources used in architectural lighting.

Sawing of my article about the Big Bang

Big Bang theory is the prevailing theory of the origin of the universe and its development. Its main argument is so-called 'galaxies escape'. The analysis of the light from galaxies shows that the spectral lines are shifted to the red part of the spectrum. Based on the Doppler effect interpret this to mean that 'most' of galaxies receding from the observer. It is said that in the past was galaxies closer together. If we goes even further back in time, this means that the entire universe was compressed into a point that exploded. There we have Big Bang. The author has published an article in the topic above . But the article was totally sawn by an opponent. The author would like this letter to defend themselves and want to show their duel for everyone to judge what is right or wrong, or better said how much it is right and how much is it wrong!
