Science and Human Beings
Science enables human beings to progress rapidly and lead a better life. For example, 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.
Meanwhile, sometimes science does have some side effects. A good illustration of this is atomic energy, which can destroy human beings completdy when used in nuclear weapons.
Anyhow, it is men who develop science. And science, in turn, will do us good in general. As for its side effects, I believe human beings will be rational enough to avoid them or keep them under control.
