Science for self-reliance has, in recent years, become a matter of great concern for Third World and developing nations.

With such skills, these nations ;viii be better able to utilize the resources which their own lands supply. There exists an acute need for scientists, engineers, technicians, economists, physicians, lawyers skilled in domestic and international law, and most importantly, perhaps, teachers and administrators with a commitment to sharing their skills with the underdeveloped nations. These nations would then be able to devise educational strategies and techniques needed to teach their students essential skills.
