Chapters on some Topic

here i organized some posts and group them into a more readable sequences. Enjoy.

reader should not be confused with the post’s name, coz i rearranged them so make it more “step by step” by reading one by one.  Hope can help all beginner. ( who switched field when enter doctoral course and want to pick up things quick and deep )
