As the development of biosciences, once people find the object that affect human beings' knowledge gaining and manufacture it, there will be a great revolution in future education. That is, giving people different objects by society's needs and their body characteristics. If they got that object, they will surely get the knowledge and put it into practice. And people can live in tranquillity to create a more beautiful society.
