... Теория плоских вещественных кривых ? одно из красивейших применений маломерной топологии. Плоская аффинная вещественная алгебраическая кривая ? ... При переходе от аффинной плоскости к проективной различие между эллипсом и гиперболой исчезает и мы получаем два типа неособых кривых второй степени. При возрастании степени задача классификации неособых кривых становится все более и более трудной. ...

... Sternberg Astronomical Institute , Moscow University . ... Present edition unites two parts of Catalogue of interacting galaxies by B.A.Vorontsov-Velyaminov: the first part (Part 1) containing 355 systems was published in 1959 [1] and the second one (Part 2) with 497 objects - in 1976 [2].Thus two published parts of Catalogue include 852 interacting systems. ... All new of them (1162 by number) were taken from the comments to the galaxies in Morphological catalogue by Vorontsov-Velyaminov et al.[ ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... We guess it's almost impossible to create the site nowadays where all space relative philatelic materials (postage stamps, stationary, postal marks etc.) would be registered and presented. ... We tried to make such a step in April 2005, placing at the site first images of postage stamps with portraits of astronauts (cosmonauts, spacionauts, taikonauts:). ... All illustrative material (or simply speaking, all scans of stamps) are grouped in four sections: Countries , Years , Astronauts and Flights . ...

Each spiral galaxy has a core a flat disk where the spiral brancher locate. The stars and interstellar substance of spiral galaxies rotate around the core. ... In normal galaxies, such as our Galaxy, the great brightness of the core is accounted for the high concentration of stars. ...

... Here are some tips on how to get the best guiding out of our current system. ... NA2 Guider Tips . ... Optical double stars, late-type galaxies, and bipolar PNs may pose a problem for guiding, as will objects where you desire to observe a position away from the bright center (e.g., SNs near bright galaxies). ... Field Star is good if your object is too faint or asymmetrical for Boresight guiding, or if you need the slit to be off-center. ... Use Field Star guiding almost always. ...

This explains why we often see one very bright jet ? ... Quasars, the most powerful sources, often show a prominent jet, strong radio galaxies like the one to the right more usually don?t. The most powerful of these radio sources can be detected at immense distances in the Universe ? ...
