"Idle speculation" has no place in
science, but "speculation" is its very lifeblood, a wellknown physicist
believes.
The more fundamental and far-reaching a scientific
theory is, the more speculative it is likely to be. It is erroneous to believe
that science is only concerned with "pure facts", for mere accumulation of facts
is a primitive form of science. A mature science tries to arrange facts in
significant patterns to see relationships between previously unrelated aspects
’of the universe.
A theory that does not suggest new ways of
looking at the universe is not likely to make an important contribution to the
development of science. However it is also important that theories are checked
by new experiments and observations.

The world is known to us through many
senses, not just hearing, smell, vision, and at close range, touch and
taste.
Our skins let us know whether the air is moist or dry,
whether surfaces are wet without being sticky or slippery. From the uniformity
of slight pressure, we can be aware how deeply a finger is thrust into water at
body temperature, even if the finger is enclosed in a rubber glove that keeps
the skin completely dry. Many other animals, with highly sensitive skins, appear
to be able to learn still more about their environment. Often they do so without
employing any of the five senses.
By observing the capabilities
of other members of the animal kingdom, we come to realize that a human being
has far more possibilities than are utilized. W
A. through skin contact
B. from the even distribution of pressure
C. from the sense of direct touch
D. through the difference in temperature
