This research explores the relationship between science classics, science textbooks, and popular science books from Lakatos's 'Scientific research programmes'. This 'programmes' includes two parts: hard core and protective belt. And, this 'programmes' includes two methods: negative heuristic and positive heuristic. We find: science textbooks and popular science books are compatible in the creativeness of science classics. In other words, science classics have both scientific knowledge and scientific enthusiasm. Finally, we believe in diversification of science classics curriculum from Lakatos's 'diversification of theory'.
