We consider the problem of obtaining the observed galaxy rotation curves using only luminous matter as a source of gravity. The basic idea is that any star belonging to a galaxy possesses both translational and rotational motion. On the basis of this idea, we introduce 7D space-time in which the galaxy rotation equation corresponds to the observations. As a key proof of the correctness of the suggested model, we use a theoretical justification of Skumanich's empirical law. The main advantage of the new model is an explanation of galaxy rotation curves without dark matter.
The article analyzes the use of new digital technologies in transport education considering the Moscow Automobile and Road Construction State Technical University (MADI) as an example. The results Massive Open Online Courses (MOOC) and other electronic systems in the training of engineers using on specialty «Land transport and Technological Vehicles» are given. Positive opportunities of online courses using arise in the organization of student extracurricular activities and the implementation of a differentiated approach in training. Different content of online courses in the areas of training makes it difficult to use MOOC in the practice of general engineering education. The authors suggest using the Modular Object-Oriented Dynamic Learning Environment (Moodle) which is a free web application that provides to create websites for online learning. The experience of using the online resource «Information system MADI» («IS-MADI: Physics») to study Physics, created by MADI’s teachers, is also considered. This experience makes to conclude that using of the Internet resource «IS-MADI: Physics» awakes interest of students to learn Physics. In a whole students begin to understand that knowledge of Natural Science disciplines gives them powerful tool to create and to exploit modern cars and roads, they begin understand importance of Physics.
The equation of nonmetricity field fluctuations is derived for the Weyl-Cartan space. A correlation is found between densities of various kinds of matter in the inflating Universe. The mass of the nonmetricity field quantum defined as the quantum of interaction with matter having nonzero dilaton charge is calculated.
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.
