Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

It does not follow because many books are written by persons born in America that there exists an American literature. Books which imitate or represent the thoughts and life of Europe do not constitute an American literature. Before such can exist, an original idea must animate this nation and fresh currents of life must call into life fresh thoughts along the shore.
Margaret Fuller
Reporter: How many people who labor in the same musical vineyard in which you toil - how many are protest singers? That is, people who use their music, and use the songs to protest the, uh, social state in which we live today: the matter of war, the matter of crime, or whatever it might be.
Bob Dylan: Uh, I think there's about, uh...136.
Reporter: You say about 136, or you mean exactly 136?
Bob Dylan: Uh, it's either 136 or 142.
Bob Dylan
On some positions, cowardice asks the question, is it expedient? And then expedience comes along and asks the question, is it politic? Vanity asks the question, is it popular? Conscience asks the question, is it right? There comes a time when one must take the position that is neither safe nor politic nor popular, but he must do it because conscience tells him it is right.
Martin Luther King Jr.
I would rather be ashes than dust! I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot. I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet. The function of man is to live, not to exist. I shall not waste my days trying to prolong them. I shall use my time.
Jack London
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of other's opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
