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.
There are not many books that devote a full subject on the Sun. as I read this in April 2020 the book has hardly been out but it contains facts right up until the summer of 2020.
Technical terms are explained with diagrams it is very readable. This is from someone who has recently read ‘astronomy for dummies’.What makes things nice is that they mention the names of various people who have discovered certain things about the Sun and often there are some interesting facts about the persons themselves.
The only thing one could suggest for a second edition is perhaps some colour photographs.
This is the type of book that should come out every few years to keep the general public up to date with updates on new discoveries and information obtained through investigation and observation by the solar scientific community. I am no physicist but a geek that observes the sun in white light and h-alpha and was pleased with the contents and new information available to me in this book. If you have any interest in the sun and how we depend on it for our existence, at this time, then I would recommend you read it.
