“I have found Ray Chang’s P Chem book to be the ideal textbook for students from the life sciences. Whereas so many other textbooks seem to be written for the instructor, this text works well with students who have traditionally struggled with this course.” “I adopted the P Chem text by Raymond Chang here at McGill two years ago, for a course populated with ~180 biochemistry and biology students, many of them ‘pre-med.’ I had formerly used a well-known text by a different author, but I (and the students) found it a little short on good explanations, and there were many errors in the end-of-chapter problems and answers. I am very pleased with how the Chang text approaches thermodynamics, especially applications, such as in the chapter on macromolecules. Similarly, I very much appreciate the biological emphasis in this text, and especially the relevance of the problems. Overall, I consider this to be an excellent text.” “This book offers an alternative approach to physical chemistry that is particularly well suited for those who want to pursue a course of study more focused on the biological sciences.” “A distinct and excellent publication worth recommending to biological chemists…I have learnt something new about biology, [the book] is very refreshing in its aims and clarity.” |
