if you think you know what is going on, you haven’t got a clue about what’s going on. - 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.

Creativity begins with an affinity for something. It’s like falling in love.

"What is going on here? Why are students not mastering what they ought to be learning? It is my belief that, until recently, those of us involved in education have not appreciated the strength of the initial conceptions, stereotypes, and "scripts" that students bring to their school learning nor the difficulty of refashioning or eradicating them. We have failed to appreciate that in nearly every student there is a five-year-old "unschooled" mind struggling to get out and express itself. Nor have we realized how challenging it is to convey novel materials so that their implications will be appreciated by children who have long conceptualized materials of this sort in a fundamentally different and deeply entrenched way."
