科学(Science)、技术(Technology)与工程(Engineering)之间有着密切的联系,互相促进,但不完全是上下游关系。在人类发展历程中,技术在先,从旧石器时代到新石器时代,只是对石料进行了人为的加工,成为更符合人类需要的器皿或武器;到了青铜器时代才有了人工合成的材料(青铜是铜与锡共熔的合金)。即使我国古代对世界历史做出过巨大贡献并产生了深远影响的四大发明,也都属于技术的范畴。这些技术促进了人类的进步,使人类变得更加聪明,社会文明的发展愈来愈快。
Science, Technology and Engineering are closely linked and mutually reinforcing, but not completely upstream and downstream. In the history of human development, technology first, from the Paleolithic to the Neolithic, but the man-made stone processing, become more in line with human needs of the vessels or weapons; to the Bronze Age, there was only a synthetic material (bronze Is a copper and tin eutectic alloy). Even the four great inventions that have made tremendous contributions to the history of the world in ancient China and have had a profound impact have all belonged to the category of technology. These technologies have promoted the progress of mankind, made mankind smarter, and made the development of social civilization faster and faster.
