Why?" I questioned in puzzle ment . He smiled and drew a circle on a piece of paper, then made a dot in its circumference and asked me,"Which way is the shortest to reach the symmetrical dot in the circumference from this point?""Diameter , I responded , and with this answer I suddenly realized that I was lucky enough to live a diametrical life , namely, a very smooth life . Since I exposed myself to the research in materials, I have been aspir ing to become a scientist, and God has blessed me with a diametrical life without any waste of time or life.
