2005 Control and Under Control The greatest contribution of science and technology, in other words, of civilization is to make human's life more convenient, more comfortable, safer, and being able to satisfy people's needs faster. But more one relies on the technology, more degradation we could expect in some function of mankind. For instance, when you calculate the full amount, you use the calculator; you use PDA while checking the calendar. Human's mathematics, physics and memory are reduced because of various kinds of technological products of convenient use. People rely on the technology slowly and strongly. While the technology products could not be used normally, various kinds of activities of people will receive a great impact. Think about this: Is human controlling technology, or is human being controlled by technology?
