The first generation of museums are what might be called natural museums which, by means of fossils, specimens and other objects, introduced to people the evolutionary history of the Earth and various kinds of organisms. The second generation are those of industrial technologies which presented the fruits achieved by industrial civilization at different stages of industrialization. Despite the fact that those two generations of museums helped to disseminate / propagate / spread scientific knowledge, they nevertheless treated visitors merely as passive viewers.

The third generation of museums in the world are those replete with / full of wholly novel concepts. In those museums, visitors are allowed to operate the exhibits with their own hands, to observe and to experience carefully. By getting closer to the advanced science and technologies in this way, people can probe into their secret mysteries.
