“Physical concepts are
free creation of the human mind, and are not, however it may seem, uniquely
determined by the external world. In our endeavor to understand reality we
are somewhat like a man trying to understand the mechanism of a closed watch.
He sees the face and moving hands, even hears it ticking, but he has no way
of opening the case. If he is ingenious he may form some picture of a
mechanism which could be responsible for all the things he observes, but he
may never be quite sure his picture is the only one which could explain his
observations. He will never be able to compare his picture with real
mechanism and can not even imagine the possibility or meaning of such a
comparison.” (A. Einstein)
