requires that new, so-called "modern" laws be consistent with and indeed build upon--those
traditional principles.
Even in the arts--where one might think that true originality must surely reside--so-called
"new" ideas almost always embrace, apply, or synthesize what came earlier. For example,
most "modern" visual designs, forms, and elements are based on certain well-established
aesthetic ideals--such as symmetry, balance, and harmony. Admittedly, modern art works often
eschew these principles in favor of true originality. Yet, in my view the appeal of such works
lies primarily in their novelty and brashness. Once the ephemeral novelty or shock dissipates,
these works quickly lose their appeal because they violate fn:rnly established artistic ideals. An
even better example from the arts is modern rock-and-roll music, which upon first listening
might seem to bear no resemblance to dassical music traditions. Yet, both genres rely on the
same 12-note scale, the same notions of what harmonies are pleasing to the ear, the same
forms, the same rhythmic meters, and even many of the same melodies.
When it comes to the natural sciences, however, some new ideas are truly original while
others put established ideas together in new ways. One striking example of truly original
scientific advances involves what we know about the age and evolution of the Earth. In e~rlier
centuries the official Church of England called for a literal interpretation of the Bible, according
to which the Earth's age is determined to be about 6,000 years. If Western thinkers had simply
put these established ideas together in new ways the fields of structural and historical geology

might never have advanced further. A more recent example involves Einstein's theory of
relativity. Einstein theorized, and scientists have since proven empirically, that the pace of time,
and possibly the direction of time as well, is relative to the observer's motion through space.
This truth ran so contrary to our subjective, linear experience, and to previous notions about
time and space, that I think Einstein's theory can properly be characterized as truly original.
However, in other instances great advances in science are made by putting together current
theories or other ideas in new ways. For example, only by building on certain well-established
laws of physics were engineers able to develop silicon-based semiconductor technology. And,
only by struggling to reconcile the quantum and relativity theories have physicists now posited
a new so-called "string" theory, which puts together the two preexisting theories in a
completely new way. 感谢您阅读《GRE作文范文大全(40) 》一文,出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
