Understanding is not absolutely final. What's now right could be wrong later.
In reality, this is almost always true in science.
Evolution is the phenomenon of change and the challenge of the next time cycle will involve the creation of constructs that will provide the kind of dynamic knowledge base that can assist the challenges of tomorrow (involving both fundamental and extended information).
They were maps that lived, maps that one could study, frown over, and add to; maps, in short, that really meant something.
Science is a series of judgments, revised without ceasing.
There is not a piece of science, but its flank may be turned tomorrow.
Science does not mean an idle resting upon a body of certain knowledge; it means unresting endeavor and continually progressing development toward an end which the poetic intuition may apprehend, but which the intellect can never fully grasp.
Knowledge in the Internet Age - networked knowledge - is becoming more like what knowledge has been in the past few hundreds years for scientists: it's provisional; it's a hypothesis that is waiting to be disproved.
Like anything else, knowledge must evolve.
Knowledge is no longer an immobile solid; it has been liquefied. it is actively moving in all the currents of society itself
It is just as important to make knowledge live and keep it alive as to solve specific problems.
