Hi Jackson,
I understand what you're saying about science books and "those science book authors," but whom are you addressing in your opening sentences? "I don't have any complain from
you." Who are "you"? - A group of teachers? Have they been forced to teach science without textbooks? How did that come about? Have you taken away their books in order to teach "those authors" a lesson? Why are you punishing the teachers? It would be difficult to correct this without knowing what the heck is going on.
Best wishes, - A.
