"It's important to listen to what scientists..." - Quote by Barack Obama

“America is not the crude stereotype of a self-interested empire. The United States has been one of the greatest sources of progress that the world has ever known. We were born out of revolution against an empire. We were founded upon the ideal that all are created equal. And we have shed blood and struggled for centuries to give meaning to those words, within our borders and around the world. We are shaped by every culture. Drawn from every end of the Earth, and dedicated to a simple concept, E pluribus unum: Out of many, one.”

“I've sought a constructive relationship with Russia, but what I have also been is realistic in recognizing that there is some significant differences in how Russia views the world and how we view the world.”

“Keep exploring. Keep dreaming. Keep asking why. Don’t settle for what you already know. Never stop believing in the power of your ideas, your imagination, your hard work to change the world.”

“Those who fall in love with practice without science are like a sailor who enters a ship without a helm or a compass, and who never can be certain whither he is going.”

“Our theories are wedged and controlled as nothing else is. Yet sometimes alternative theoretic formulas are equally compatible with all the truths we know, and then we choose between them for subjective reasons. We choose the kind of theory to which we are already partial: we follow 'elegenace' or 'economy'”

“I say that the power of vision extends through the visual rays to the surface of non-transparent bodies, while the power possessed by these bodies extends to the power of vision.”

“Being is the great explainer.”

“The secret is to know how to lie" he used to say, " and to know when someone's lying to you". His father, Steve eventually decided, must have known how to lie.”

“Broader and deeper we must write our annals, from an ethical reformation, from an influx of the ever new, ever sanative conscience, if we would trulier express our central and wide-related nature, instead of this old chronology of selfishness and pride to which we have too long lent our eyes. Already that day exists for us, shines in on us at unawares, but the path of science and of letters is not the way into nature. The idiot, the Indian, the child, and unschooled farmer's boy, stand nearer to the light by which nature is to be read, than the dissector or the antiquary.”
