I have loved to read since I was little. I would borrow many books from the library and still borrow to this day, but I also purchase books (mostly for my kids) and freebies on Kindle. I read as much as I can daily. Sometimes I read several books at one time. I don't have a preference of paper book over an ebook, I just love to read. Keeping lists of what I have read is a good way for me to remember.
I got this book for free (and right now it is free). I know that everyone learns differently and so I got this and a few others. I really enjoy the story and then an explanation follows and it helps to make sense for someone who needs a different way to look at the problem.
My girls will be assigned this after New Year. I think it will help them to understand some Physics principles.
