I have read third book of Adams 101 series, and I can say readily that Astronomy 101 is the best one. Author regularly classified nearly all matters which are related to cosmos. Before to start reading, she has tried to enlighten readers about some subjects, such as units of measurement. This is helpful attempt for readers, in particular who do not know much about astronomy.
Furthermore, author has began with the Sun, and then has explained all inner and outer planets, in turn, at length. I have learned a lot of things about both the Sun and planet that is really fascinating. For example, even though the Sun looks like yellowish, it is indeed white.
Moreover, besides planets which orbit our solar system, author has mentioned about comets, meteors, asteroids, stars, and so on. I have always been wondered how stars birth and death. Thanks to this book, I am a little bit satisfied. In addition to these basic and nearly simple subjects, big bang, dark matter, dark energy and black holes also were elucidated.
However, you should not forget that it is a crash course, and this means is it contains a lot of title. That is why author describes all matters briefly.
The supreme example of economic pressure applied against freedom of thought is Soviet Russia, where, until the trade agreement, the Government could and did inflict starvation upon people whose opinions it disliked—for example, Kropotkin.
This is the first book I have ever read which is written by Bertrand Russell. Frequently, I have seen his name in various book, and I wanted to met him. Therefore I chose this book, because it is brief. And then when I had finished book, realized that it is magnificent choice.
Firstly, I can easily say that Bertrand Russell is an outspoken. That is why, in the beginning of the book he mentioned his religious belief. After that, he talks about some sorts of difficulties which he was exposed in various field, such as education, because of their religious faith. Hence, he expresses three subjects which are misused by people, in particular by statesman, namely education, propaganda, and economy. He claims that every nation strive to imbue their students or citizens with their historical glories.
In addition to a brief summary, I want to mention about one example which is given by author. When Einstein's theory appeared, it was accepted by scientists, without fighting. However, if his theory had occurred in the sphere of politics or religions, what would happened?
To sum up, I strictly suggest that every people must read it.
Aristotle asserted that big objects fall faster than little ones, for example, and that if one object had twice the weight of another, it would fall twice as fast. Although this is mistaken, no one doubted it until the Italian astronomer Galileo Galilei disproved the idea in 1590.
