Why does the Foundation concentrate its
support on basic rather than applied research Basic research is the very heart
of science, and its cumulative product is the capital of scientific progress, a
capital that must be constantly increased as the demands upon it rise. The goal
of basic research is understanding, for its own sake. Understanding of the
structure of the atom or the nerve cell, the explosion of a spiral nebula or the
distribution of cosmic dust, the causes of earthquakes and droughts, or of man
as a behaving creature and of the social forces that are created whenever two or
more human beings come into contact with one another--the scope is staggering,
but the commitment to truth is the same. If the commitment were to a particular
result, conflicting evidence might be overlooked or, with the best will in the
world, simply not appreciated. Moreov A. encourages basic research B. devotes more than 90% of its research and development funds to applied research C. spends far more on applied research than on military problems D. opposes the Foundation’s grants to basic research [判断题]水流开关未打开的情况,冷水机组也可以开启。
