science enables human beings to progress rapidly and lead a better life. for eample, edison＇s invention of the light bulb brought our gloomy life to the end and created a bright world for us. another case in point is watt＇s discovery of the steam engine, which triggered the industrial revolution in the western countries, and later all over the world.
