I'm reading a physics textbook now and taking personal notes as I read. I'd like to put my own personal notes online for free so that other members of my lab group can refer to them easily.
How can I avoid legal and moral plagiarism?
The equations - I assume the textbook publisher does not own the math/physics equations in the book. In my notes, should I cite the textbook and other references from the textbook?
The words - I know I cannot just copy the entire text online with one citation. However, the physics will need some explanation. Would it be enough rewrite explanations in my own words? How many citations of a book is too far towards just copying the book?
The diagrams/pictures - I assume the textbook publisher owns or bought the rights to the diagrams and pictures in the book. How can I use diagrams in my notes? Is redrawing diagrams in my own way enough?
