i'm taking second semseter of classical mechanics next semester. here's a syllabus of whats going to be covered. apparently the class uses Classical Dynamics of Particles & Systems/ Marion and Thornton. I saw on this site that the book is terrible. i'm not sure which book is appropriate for intermediate mechanics. i guess its between Landau, L.D., Lifschitz, E.M., Course of Theoretical Physics, V. I: Mechanics and Goldstein, H., Classical Mechanics if anyone can give more feedback concerning those two textbooks that would be great. or if theres another book i should consider please let me know.
