Comments on "From 'Reaction Concept' to 'Conjugate Gradient': Have We Made Any Progress?" and Reply to Dr. Wang's Comments

Dr. Sarkar's paper, as the feature article of the August 1989 AP-S Newsletter [1], provides a vivid and informal (and therefore perhaps more revealing and informative) discussion on a subject of common interest. However, he has also expressed several views which, according to my observation, are not shared by many students of the field. Since Dr. Sarkar specifically referenced my work as an introductory basis for his discussions, and since he has, to some extent, misinterpreted my opinions, I would like to offer the following comments and clarifications, which hopefully will provide the readers a more clear and balanced view on this subject.
