Using scores of examples from a wide variety of authors and disciplines, the author - himself a writer and physicist -- demonstrates the difference between strong and weak scientific writing, and how to convey ideas to the intended audience. In addition, he gives advice on how to start writing, and how to revise drafts, including many suggestions about approaching a wide variety of tasks - from laboratory reports to grant proposals, from internal communications to press releases - as well as a concise guide to appropriate style and usage.
