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

“Space flight: living in zero gravity”.
Gravity existing on Earth for millions of years, has contributed to the development of all life on Earth organisms and invade their system of life as a factor contributing to their successful functioning in the gravitational field of the Earth. Opening up opportunities to systematically study the impact of eliminating gravity, spaceflight facilitated the accumulation of information and facts that contributed to the development of the theory on the role and place of gravitational mechanisms in the various body systems and the development of a new physiological science — gravitational physiology.The most gravity-dependent system of the body is the propulsion system, in which gravity has played such an important role that today we have the right to determine its evolution as the evolution of the struggle of living organisms with gravity wrestling success ended in mammals the development of a strong skeleton, strong muscular system, management systems movements, and information systems able to ensure the perfection of movement in complex conditions of the gravitational field and its izmeneny.

It happened because of that. the density of gases inside of it are incredibly low. Actually, in our Galaxy the number of stars is estimated at least 200 billion. White ovals on Jupiter limited circumferential zones. however, they can interact and form a region of chaotic clouds. On the Photo from a Space telescope named Hubble. made in ultraviolet rays. auroras appear as an annular zone around the poles of the planet. At the very least. its atmosphere is mostly hydrogen. The picture is composed of images. cameras made by Galileo using three filters. and shows. how it will look ancient rotating system of clouds. if you fly right over her. Most people go to work in the office. but my dream is to work at home.
Can you believe it. that many centuries ago.
The largest planet in the Solar system — Jupiter.
The largest planet of the Solar system The largest planet of the Solar system is.
Pluto is a planet or not. it was formulated the concept of determining Liberona the sky recently, a completely new object, a reddish point. which is very weakly visible. And that is what the scientist William Herschel was able to determine the rotation period of the planet. Instead of the Sun in our Solar system or somewhere on the outskirts. where it will not be visible. However by weight, it is second largest planet in three times. Continue reading
