At the end of last week in Ulyanovsk has started an interesting project Simple science. Its initiator is the teacher of UVAU HA Leonid Podymov.
— The main purpose of my lectures is to educate. I would like to tell Ulyanovsk on the latest and most interesting achievements in modern science into simple language so that it is clear even to the unprepared listener, — says the organizer of the “Simple science”.
Leonid physicist by education, so the project is focused mainly on natural Sciences. In particular, the first lecture was devoted to astronomy — or rather, cosmic distances and scale.
— Many people know that, for example, our Solar system is big. But it is actually an ordinary person is unlikely to adequately represent these scales and distances — simply because it is not something to compare. I tried using a few simple techniques to bring clarity in such comparisons, says the teacher.
So, during the speech he invited the audience to spend with him a few thought experiments.
— Let’s imagine that our planet has shrunk to the size of a standard basketball ball whose radius 12.2 centimeters. If we reduce all other razmery accordance with a given scale, we get the following illustrative figures: the Sun will be a ball with radius 13 meters. Continue reading

New ships USA: Cygnus, Dragon, CST-100, Orion.
Existing ships of Russia: Progress M, Soyuz TMA-M.
Existing ships of the United States: no.
Signus together with Soyuz TMA-M
Soyuz TMA-MC is a Russian multi-seater spacecraft for flight in earth orbit.
New upgraded version of the spacecraft “Soyuz TMA-M”. The update will affect almost every system of manned spacecraft. The first launch is planned no earlier than 2016.
The main points of the program of modernization of the spacecraft:
the energy-conversion efficiency of solar cells, will be enhanced through the use of more efficient Photovoltaic cells;
the reliability of rendezvous and docking of spacecraft with the space station due to the change in engine installation of the mooring and orientation. Continue reading
In the new year period in December 2015 on the horizon we can observe the double-tailed comet Catalina C/2013 US10 Catalina.
Information, data, interpretation of the significance of the comet Catalina.
Astronomical, cosmopolitisme and mythological content of the comet Catalina.
Comet C/2013 US10 Catalina.
Good news for all lovers of the starry sky — comet C/2013 US10 Catalina two weeks ago passed perihelion, the closest approach to the Sun, and now flies back to the depths of space. Until January 17, Catalina will approach closer and closer to the Ground, and in the first weeks of December, the sky in the middle latitudes it reaches the maximum sky brightness. This is a great chance to watch the comet live — even more so that the next time Catalina will be visible only after a few million years. Continue reading
