The idea of having an ambient space-time of some specific dimension seems to play less of a role of string theory than in conventional physics, and certainly less than the kind of role that I would myself feel comfortable with. It is particularly difficult to assess the functional freedom that is involved in a physical theory unless one has a clear idea of its actual space-time dimensionality.

The Paleolithic hunters who painted the unsurpassed animal murals on the ceiling of the cave at Altamira had only rudimentary tools. Art is older than production for use, and play older than work. Man was shaped less by what he had to do than by what he did in playful moments. It is the child in man that is the source of his uniqueness and creativeness, and the playground is the optimal milieu for the unfolding of his capacities.
Eric Hoffer
No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
John Donne
Holy Tradition is neither a tradition of men, nor a philosophy, nor some kind of trickery, but is the word of God that He delivered to us personally. The great Apostle Paul teaches and exhorts us to keep with vigour the traditions, saving; "Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle."
Cleopa Ilie
Evolutionary theory tends to explain quite well in retrospect how various species emerged. It's not very good on prediction. Nevertheless, one cannot say that there isn't a lot of knowledge that's been obtained in this field. In the same way, with these complex physical phenomena between solid state physics, you can say a lot of things without necessarily knowing the next step.
Kenneth Arrow
good art means the ability of any one man to pin down in some permanent and intelligible medium a sort of idea of what he sees in Nature that nobody else sees. In other words, to make the other fellow grasp, through skilled selective care in interpretative reproduction or symbolism, some inkling of what only the artist himself could possibly see in the actual objective scene itself.
