The discussion centers on "Classical Dynamics: A Contemporary Approach" by Jorge José and Eugene Saletan, highlighting both strengths and weaknesses. A major drawback noted is the use of summation notation throughout the text, which can detract from readability. However, the book is praised for its encyclopedic content and extensive bibliography, although it sometimes lacks justification for certain concepts, such as the principle of least action. The text excels in providing geometrical intuition, making it a valuable supplement to other works, particularly Arnold's, by aiding in the visualization of classical dynamics. Overall, while it may not serve well as a standalone textbook, it is highly recommended as a supplementary resource.
