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 / notions
/ ideas. 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.
The
China Museum of Science and Technology is precisely
one of such museums. It has incorporated some of
the most fascinating features of those museums with
international reputation. Having designed and created
exhibits in mechanics, optics, electrical science,
thermology, acoustics, and biology. Those exhibits
demonstrate scientific principles and present the
most advanced scientific and technological achievements.

If people mean anything at all by the expression
"untimely death", they must believe that
some deaths run on a better schedule than others.
Death in old age is rarely called untimely---a long
life is thought to be a full one. But with the passing
of a young person, one assumes that the best years
lay ahead and the measure of that life was still
to be taken.
History
denies this, of course. Among prominent summer deaths,
one recalls those of Marilyn Monroe and James Deans,
whose lives seemed equally brief and complete. Writers
cannot bear the fact that poet John Keats died at
26, and only half playfully judge their own lives
as failures when they pass that year. The idea that
the life cut short is unfilled is illogical because
lives are measured by the impressions they leave
on the world and by their intensity and virtue.
