In this paper, the analytical solutions of Brans-Dicke (B-D) equations with cosmological constant are presented, in which the equation of state of the universe is P=mÙ° ρ , under the assumption φRn=c between the B-D field and the scale factor of the universe. The flat (K=0) Robertson- Walker metric has been considered for the metric of the universe. These solutions are rich in the sense that ...
module over a ring is a general mathematical concept for many examples of mathematicalobjects that can be added to each other and multiplied by scalar numbers.In this paper, we consider a module over a ring as a universe and by using the notion of reference points, we provide local approximations for subsets of the universe.
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...
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...
The English Dominican Herbert McCabe highlighted some ideas of Thomas Aquinas on the knowability of God and on creation, which can usefully challenge some widespread commonplaces. The purposes of this article are two: to present McCabe’s sophisticated doctrine on the knowability of God and on creation in a systematic way, and to put this doctrine into its historical context. In the scattered an...
Human is the god’s caliph on earth and moving toward perfection is the most important feature of him. Attention to the perfect man and its recognition is one of the subjects that have considered by various religions. The perfect man in mysticism is like a mirror that has two faces: divine names and attributes manifest on one of the faces and the infallible god observes itself on it and on the o...
The paper presents a novel type of fuzzy sets, called time-Varying Fuzzy Sets (VFS). These fuzzy sets are based on the Gaussian membership functions, they are depended on the error and they are characterized by the displacement of the kernels to both right and left side of the universe of discourse, the two extremes kernels of the universe are fixed for all time. In this work we focus only on t...

The model of the homogenous and isotropic universe with two spaces is considered. The background space is a coordinate system of reference and defines the behaviour of the universe. The other space characterizes the gravity of the matter of the universe. In the presented model, the first derivative of the scale factor of the universe with respect to time is equal to the velocity of light. The d...
