Science covers the broad field
of knowledge that deals with
observed facts and the
relationships among those
facts. The word «science»
comes from the Latin word «scientia», which means
«knowledge». Scientists
study a wide variety of
subjects. Science has enormous
influence on our lives. It
provides the basis of much of modern technology - the
tools, materials, techniques,
and sources of power that
make our lives and work
easier. The discoveries of
scientists also help to shape our views about ourselves
and our place in the universe.
Modern science and
technology have changed our
lives in many dramatic ways.
Airplanes, automobiles, communications satellites,
computers, plastics, and
television are only a few of
the scientific and technological
inventions that have
transformed human life. Research by nuclear physicists
has led to the development of
nuclear energy as a source of
power. Agricultural scientists
have developed better
varieties of plants and highly effective fertilizers. The
development of antibiotics
and other new drugs has
helped to control many
infectious diseases. Studies in
anatomy and physiology have led to amazing new
surgical operations and to the
invention of life saving
machines that can do the
work of such organs as the
lungs, kidneys, and heart. Although scientific and
technological achievements
have benefited us in many
ways, they have also created
serious problems. The rapid
growth of industrial technology, for instance, has
resulted in such grave effects
an environmental pollution
and fuel shortages.
Breakthroughs in nuclear
research have led to the development of weapons of
mass destruction. Some people
fear that biological research
will produce new disease -
causing bacteria or viruses
that resist drugs. People are also concerned that
computerized information
system may destroy personal
privacy. But science itself is
neither good nor bad. The uses
that people choose to make of scientific knowledge
determine whether that
knowledge will help or harm
society.
