The development of computers require newer mathematical fields, concepts, and skills. Because computer hardware and software are more complicated now than ever, it has almost come to a point where it is dangerous to use them without the proof of their accuracy. However, to reduce the problem, we have considered THEAX (mathematical language) and a proof checker to introduce the new mathematical skills. In addition, we are also helping with the research for MISER, which was developed by Dr. A. Trybulec of Warsaw Univ. and others with the same idea. Also, computers are pointing out the necessity of looking at all objects digitally. Thus, we have made a theory of Finite Topology which we are working to develop. This theory will influence Geometry, Analysis, Algebra, and Physics greatly with the wider field than previously predicted. Using a common language of mathematics permits us to minimize human misunderstanding and prejudice so that the truth can be acquired and allow young people to have the courage to face reality. Let there be peace in the world!
