Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
The Astronomy Book is big, heavy, and follows the format of all the other "Blank Book" publications. I have the print version. Because it is part of the large series it follows the format of its sister publications, and that makes this particular book tough to follow. The information is presented in a scattered form that, in this instance, confuses me and I have read several of these books in both Kindle and print format.
The format used also breaks up the flow of ideas, so one moment you are studying the universe of the Middle Ages and the next you are looking at how we can tell how far away stars are, a very modern undertaking. The book would be improved by rethinking the order in which the subject matter is presented. Some things work well with the "Blank Book" format but this one did not.
The information was accurate as far as I read, but I couldn't get past half way because of my internal frustrations and confusion. I ended up skipping around. AD2
