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
Oceans, of course, is extensive, and the mountains are impressive for its size. 7 billion people is also not a small number. Since we live on planet Earth (whose diameter is 12742 km), it is easy for us to forget how we, in fact, tiny. In order to realize it, all we need to do is look into the night sky. Looking at it, it becomes clear that we are just a speck of dust in an unimaginably vast universe. The list of objects below will help to see the greatness of man in the future.
The largest planet (by diameter 142.984 km)
Jupiter is the largest planet in the Solar system. Ancient astronomers named Jupiter king of the Roman gods. Jupiter is the 5th planet from the Sun. Its atmosphere consists of 84% hydrogen, 15% helium with small admixtures of acetylene, ammonia, ethane, methane, and water vapor hospita. The mass of Jupiter is 318 times the mass of Earth, and its diameter is larger than the earth 11 times. The mass of Jupiter is 70% of the mass of all other planets of our solar system. The volume of Jupiter can hold 1300 planets the size of Earth. Jupiter has 63 known satellites (moons), but almost all of them are very small and dim.

Equatorial diameter of Jupiter 142600 km (11 times the diameter of the earth). The period of rotation of Jupiter is the shortest of all the planets – 9h. 50min. 30C. at the equator and
9h. 55min. 40C. in the mid-latitudes. Because of the rapid rotation of this planet has strong compression at the poles. The mass of Jupiter is equal to
318 the mass of the Earth. The rotation axis of Jupiter is almost perpendicular
to the plane of its orbit (inclination of 87 degrees). The visible surface of Jupiter is an upper level clouds surrounding the planet.
Due to this, Jupiter has a relatively high albedo(0.45 m),and the details on its surface are constantly changing their appearance. From sustainable parts known Great Red spot, observed more than 300 years.
It is a huge oval formation size 35000 km in longitude and in latitude 14000 km
between the southern tropical and southern temperate bands. Color it reddish, not subject to change. Continue reading
