Data analysis for a sample of celestial bodies generally is preceded by the completeness test in order to verify whether objects are proper representatives corresponding part universe. A data set following multivariate, continuous, uniform distribution said be “complete space.” This paper introduces new approach check this any astronomical under multivariate setup. Our proposed procedure, using...

An important innovation in the geosciences is the astronomical time scale. The astronomical time scale is based on the Milankovitch-forced stratigraphy that has been calibrated to astronomical models of paleoclimate forcing; it is defined for much of Cenozoic-Mesozoic. For the Palaeozoic era, however, astronomical forcing has not been widely explored because of lack of high-precision geochronol...

The Two Point Angular Correlation Function (TPACF) is a mathematical equation that has applications in many areas. In our project, the Two Point Angular Correlation Function is used as a way to measure the probability of finding an astronomical body at a given angular distance from another astronomical body. We were given working sequential code as a starting point. The sequential code took in ...

In this paper we report an experiment that investigated the question of whether elementary school children have metaconceptual awareness of theory revision processes. Fiftytwo elementary school children (grades, 1, 3 and 5) were asked to select between phenomenological and scientific depictions of different astronomical phenomena and indicate which of these depictions were closer to “Reality” a...
