“It is good to wonder, said the philosopher. Space travel has again made children of us all”.
To be very brief and concise, that I sometimes even work, then advise, as it is a brilliant creation that deserves repeated reading.
To be a little chatty, and allow yourself to speculate about the book, we can’t help but notice, what I like about it, absolutely everything – from the atmosphere of the text, the storyline in General and how it builds up the narrative of the book. Yes. This is not a novel, or solid piece. The story is built through short stories related to each other not how much the main characters, and how the very idea that revolves around the red planet, Mars.
But she’s great as written. As these stories fascinate the imagination. How bright the picture turns out before my eyes. if you’re in the rocket, which is sent to a dark and unknown planet Mars.
I don’t want to be objective, but from me not require, right? After all, I write a review. And feedback means transfer THEIR feelings and experiences. So I couldn’t understand people who wrote negative reviews about a boring story. I can’t understand my friends who believe this book is one of the weakest ideas of the author. Continue reading
Universe – all existing world, and not having borders in time and space. The earth is one of nine planets that revolve around the sun in very similar orbits on circles. Earth is the third planet from the Sun after mercury and Venus, after Earth comes Mars, ending the inner group of planets . different small size and solid surface. Followed by the giant planets of the outer group . consisting of hydrogen and helium-Jupiter, Saturn, Uranus, Neptune and little Pluto. In the interplanetary space sweep the comets and meteoric bodies. Seven of the nine planets have satellites . they just opened more than 50. The Earth satellite – the Moon is large (fifth largest and first with respect to the mass of the planet) and causing tidal movement, covering the whole Earth from the core to the surface.
The sun and its planets are called Solar system . The diameter of the Solar system 12 billion km from the Sun significantly more Land – in 333 thousand times the mass, and 109 times the diameter. The average distance from the earth to the Sun is 149.6 million km is taken as the astronomical unit to measure distances in the Solar system. Continue reading
The dust and ion tails of comet Hale-BOPP
But, in spite of research that freedom from prejudice was very slow: for example, Louis XIV was afraid of the comet of 1680 year, because it’s considered a portent of his death. The greatest contribution to the study of the true nature of comets was made by Edmond Halley. His main discovery was the establishment of the frequency of appearance of the same comet in 1531, 1607, 1682 Passionate about astronomical research, Halley became interested in the movement of the 1682 comet and calculate its orbit. He was interested in the path of its movement, and since Newton had already conducted similar calculations, Halley turned to him. The scientist immediately gave the answer: the comet will move in an elliptical orbit. At the request of Halley Newton presented his calculations and theorems in the treatise “De Motu”, that is “On the move”. Having the assistance of a Newton, he was engaged in calculation of cometary orbits by astronomical observations. He managed to collect information about the 24 comets. Thus appeared the first catalog of cometary orbits. In its catalog Halley found that three comets are very similar in their characteristics, from which he concluded that it’s not three different comets, and the periodic appearance of the same comet. The period of its occurrence was equal to 75.5 years. She was subsequently named Halley’s comet. Continue reading
