Since "The secret melody", the author has mastered the art of extension. It can not be said of all the scientists who have tried to this task. The text is attractive, clear, bright and pictorial demonstrations, the scope of any moderately educated amateur. In short, it does not feel "crushed". Facts, ideas, phenomena exhibited by the author fully meet our Western understanding, especially since it is not a translation and Trinh Xuan Thuan is deeply imbued with French culture. The researcher does not assert, or very little. His knowledge is that of its time and one feels throughout his speech that he is infinitely tolerant and respectful of others' ideas, those of its ancient as those of his contemporaries. This is why it is evidence of that scientific honesty so rare, so respectable. We feel that this man will never end point to its educational aeuvre that his search for knowledge is essentially dynamic, he will never resign itself to have nothing more to say. May he make you share his enthusiasm, his faith and his confidence in the future of human knowledge.
