Concise and current, Writing Science in the Twenty-First Century provides practical strategies for a wide range of scientific writing tasks. The authors use a systematic rhetorical approach and plentiful examples from multiple disciplines, preparing students in all STEM fields to write and speak with confidence, accuracy, clarity, and persuasive impact. This extensively revised second edition features integrated coverage of AI throughout, introducing tools and strategies for using it both ethically and effectively. New material addresses the growing challenge of communicating science in public contexts, and exercises—already a strength in the first edition—have been expanded, offering writers more chances to apply key concepts to their own writing.
