1 99 9 The Cloudy Universe
Modelling of Extreme Scattering Events suggests that the Galaxy’s dark matter is an undetected population of cold, AU-sized, planetary-mass gas clouds. None of the direct observational constraints on this picture – thermal/non-thermal emission, extinction and lensing – are problematic. The theoretical situation is less comfortable, but still satisfactory. Galactic clouds can survive in their cu...
متن کاملCloudy Skies
Standard Gaussian-type statistics are not really adequate to describe atmospheric variability; this traditional approach implicitly dismisses fluctuations as "noise" of use only in computing a standard deviation which, together with the mean, presumably varies so little in space and time that one can meaningfully speak of "climatological" values. In geophysics, unfortunately, this approach ofte...
متن کاملA cloudy Vlasov solution
We propose to integrate the Vlasov-Poisson equations giving the evolution of a dynam-ical system in phase-space using a continuous set of local basis functions. In practice, the method decomposes the density in phase-space into small smooth units having compact support. We call these small units " clouds " and choose them to be Gaussians of elliptical support. Fortunately, the evolution of thes...
متن کاملTOMS cloudy ozone anomaly
This study investigates anomalous ozone distributions over cloudy areas in Nimbus-7 (N7) and Earth-Probe (EP) TOMS version-7 data and analyzes the causes for ozone anomaly formation. A 5 •-longitude by 5 •-latitude region is defined to contain a Positive Ozone Anomaly (POA) or Negative Ozone Anomaly (NOA) if the correlation coefficient 5 between total ozone and reflectivity is ≥0.5 or ≤−0.5. Th...
متن کاملThe Qur’an and Mysticism On The Universe of Two Sides
The universe has an exterior known as the material world and an interior called the “hereafter.” So are the Qur’an and mankind. In other words, the universe, mankind and the Qur’an have hierarchical stages. The universe and mankind comprise the physical world, but the Qur’an constitutes the Divine Law. Since the origin of all three is one single source, one can say the former matches t...
