Abstract: The author used the Method by Memorizing the Concrete Objects As- sociated with the Shapes of Arabic numerals to Produce Marvellour Ima- gination (MMOAAPMI) created by himself to memorize 105 chemical ele- ments and 300 digits of π. The result indicates that One can learn by beart very quickly and very effiently long materials which have a strong order. One can recite, without proactive and retroactive interference, from the very beginning to the end or the other way around or choose any point in the middle as the starting point to start the recitation. By using these methods, one can get in memory with a rate of nearly 100% for a hundred days, with only a revision one lay later to reinforce what is not surely memorized. The author believes that it is more appropriate to de- fine Hermann Ebbinghaus' retention curve a that of rote memory curve. The details of remembering and reciting in either direction the terms of 105 chemical elements and 300 digits of within one day and the skills to master MMOAAPMI.
