During all-Russian academic competition on descriptive geometry, engineering and computer graphics in 2011 a task was proposed. This task’s condition was as follows: two planets rotate around a star in circular orbits of different diameter, which lie in the different planes passing through the star center and located at a 30 degree angle to each other; it is known that these orbits belong to the 4th order surface. It was necessary to find the orbits diameters ratio. This geometrical task decision’s analysis is cited in the paper.

In Trubilin State Agricultural University of Kuban there are created machinery working devices as screw drums allowing the assurance of motion of bulk particles at their horizontal location and also promoting the intensity of particles interaction between each other and with the walls of screw drums which widens technological potentialities and decreases dimensions of equipment and its weight. In the paper there are shown various sorts of screw drums and analytical methods of the study of physical phenomena taking place in the contact area of bulk particles. The search of a screw drum design was carried out by the methods of descriptive geometry and engineering graphics with the aid of the “Compass-3D” program complex. The apparatus of dimensionless kinematic functions (similarity invariant) and the analysis of dimensionalities allowing the investigation not one such a case but their infinite number united by the community of properties was used.

The Cold War

70 years ago, the bloodiest of wars had ended. Literally, the next day the USA started the ruthless Cold war against the USSR. Goal – to destroy the USSR as political and military enemy. Ironically, it was the Russian Empire (and the Soviet Union – its successor) that first in the world recognized the USA as an independent state. In 1991, the goal was achieved. Russia considered the cold war over, and the USA a partner in all matters. In vain. It is no secret the CIA felt home in Russian governmental buildings. It is no secret that Department of State advisers sat in every Russian Ministry. Unsurprisingly, imposed reforms have led to destruction of industry, agriculture, and medicine. The country was flooded with imports, and Russia has lost the basic security of state. Obviously, the same benefactors from the CIA forced the Ministry of Education and Science to adopt the surrogate instead of the Soviet system of education. Moreover, the well-wishers perfectly knew that this surrogate was of very low quality. Introduction of the American system of education instead of the Soviet one is the manifestation of the cold war. Artificial confrontation of computer graphics vs. descriptive geometry arose. Enforced antagonism resulted in elimination of teaching descriptive geometry in many areas. Known: computers and computer graphics come from the USA. Note that geometry experts do not oppose to the use of computer graphics. More obscure is the position of some of our partners, when they advocate destruction of science in favor of a drawing instrument. In this mortal combat of geeks, the author sees a manifestation of the same cold war that the United States maintains with Russia. Deduction: it is so because computer graphics took all its geometric methods of constructing from descriptive geometry. Minimal program of overcoming this geometric crisis in higher education is provided.
