The old principle of yin yang, in which the dynamics of the universe are considered the result of cycles of equivalent opposite expressions interacting to create unity, is shown to be a recurring and important theme in science. This paper applies the yin yang principle to Big Bang cosmology. A model is introduced that can help to explain the reason for decelerating and accelerating expansion, dipole patterns in the Cosmic Microwave Background, the power behind inflation, galaxy clusters in filaments and sheets, galactic streaming, and dark matter effects. The principle is then used to suggest that we unify gravity with the other forces by considering it the other set of 3 forces, and quantify gravity in accordance with its dominant realm-at the other end of the large number of significant digits scale. This model can be considered in 11 dimensions.Résumé: Le vieux principe du yin yang, dans lequel la dynamique de l'univers est considérée le résultat de cycles d'expressions équivalentes opposées agissant l'un sur l'autre pour créer l'unité, s'avère d'être un thème récurrent et important en science. Cet article s'applique le principe du yin yang à la cosmologie du Bing Bang. On présente un modèle qui peut aider à expliquer la raison de l'expansion accélérant et décélérant, les modèles de dipôle dans le fond cosmique de micro-onde, la puissance derrière l'inflation, les faisceaux de galaxie en filaments et feuilles, l'écoulement galactique, et les effets de la matière sombre. Le principe est alors employé pour suggérer que nous unifiions la pesanteur avec les autres forces en la considérant l'autre ensemble de 3 forces, et quantifier la pesanteur selon son royaume dominant-à l'autre extrémité de l'échelle des grand nombre de chiffres significatives. Ce modèle peut être considéré dans 11 dimensions.
Spring powered cars speed up and then slow down. This paper presents three different methods for modelling this motion. These models express the car’s position and velocity as polynomial functions of time. They can be constructed from only one distance and two time measurements. Mousetrap cars are ideal candidates to be modelled in this way because it is obvious when the spring stops acting to accelerate these cars. This paper presents a spreadsheet which generates positive vs. time and velocity vs. time graphs using these polynomial functions. Students can use this spreadsheet to learn more about the motion of their cars. This tool also enables students to view and evaluate several different representations of that motion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
