When Einstein had thought through a problem, he always found it necessary to formulate this subject in as many different ways as possible and to pres… - Howard Gardner

Einstein's breakthrough was classic in that it sought to unify the elements of a physical analysis, and it placed the older examples and principles within a broader framework. But it was revolutionary in that, ever afterward, we have thought differently about space and time, matter and energy. Space and time-no more absolute-have become forms of intuition that cannot be divorced from perspective or consciousness, anymore than can the colors of the world or the length of a shadow. As the philosopher Ernst Cassirer commented, in relativity, the conception of constancy and absoluteness of the elements is abandoned to give permanence and necessity to the laws instead.

I readily admit that the theory (of multiple intelligences) is no longer current. Several fields of knowledge have advanced significantly since the early 1980s.

It cannot be overstated that the emphasis on visual thinking among German-speaking scientists and engineers circa 1900 was widespread. Yet in 1905 it was Einstein who combined visual thinking with Gedanken experiments and quasiaesthetic notions with dazzling results.
