I borrow this book for my physics project. I orginally thought of just skimming this bool the informatin that I need but, since this book is relatively thin, I read the whole book. I think that it is pretty inspiring how many scientist like Michael Faraday would never give up on their reseach even if it fail. I also learn that magnet could generate a electric feild and vice versa. Before reading this book, I would never know how closely related magnets and electricity is.
