Henry FordBefore printing was discovered, a century was equal to a thousand years.

Stephen HawkingOne of the things you’re doing when you make art, apart from entertaining yourself and other people, is trying to see what ways of working feel good, what feels right.
Brian EnoDogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.
Bertrand RussellI’m not the sort of person who gives up on things. The first time we crossed the Atlantic in the balloon, it crashed, and we went on and did the Pacific. First time we crossed the Atlantic in a boat, it sank, and we went on and got the record. So, generally speaking, we will pick ourselves up, brush ourselves down, and carry on.
Richard BransonGoing to Southeast Asia for the first time and tasting that spectrum of flavors – that certainly changed my whole palate, the kind of foods I crave. A lot of the dishes I used to love became boring to me.
Anthony BourdainHappy the man whose wish and care a few paternal acres bound, content to breathe his native air in his own ground.
Alexander PopeThe extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.

Samuel JohnsonI have lived long enough to satisfy both nature and glory.
Julius CaesarTake a course in good water and air; and in the eternal youth of Nature you may renew your own. Go quietly, alone; no harm will befall you.
John MuirFaith is a knowledge within the heart, beyond the reach of proof.
Khalil GibranShun no toil to make yourself remarkable by some talent or other; yet do not devote yourself to one branch exclusively. Strive to get clear notions about all. Give up no science entirely; for science is but one.
Lucius Annaeus SenecaMy discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.

Eckhart TolleAnd this, our life, exempt from public haunt, finds tongues in trees, books in the running brooks, sermons in stones, and good in everything.
William ShakespeareAmerica is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.
Ralph Waldo EmersonEven with all of the things that are so awful, if you walk into your yard and stay there looking at almost anything for five minutes, you will be stunned by how marvelous life is and how incredibly lucky we are to have it.
Alice WalkerMuch learning does not teach understanding.
HeraclitusNature hates calculators.
Ralph Waldo EmersonI got into science fiction by being interested in astronomy first.
Terry PratchettThe difficulty with this conversation is that it’s very different from most of the ones I’ve had of late. Which, as I explained, have mostly been with trees.
Douglas AdamsKnowledge is a polite word for dead but not buried imagination.
E. E. CummingsOf course humans like to explore, and we should. There’s nothing wrong with that. But it’s more than that. It’s essential for your children and your children’s children.
Jeff BezosA tree’s a tree. How many more do you need to look at?
Ronald ReaganI’d rather learn from one bird how to sing than teach ten thousand stars how not to dance.
E. E. CummingsPerhaps nature is our best assurance of immortality.
Eleanor RooseveltAll human actions have one or more of these seven causes: chance, nature, compulsions, habit, reason, passion, desire.
AristotleI think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. This attitude of mind – this attitude of uncertainty – is vital to the scientist, and it is this attitude of mind which the student must first acquire.
Richard P. FeynmanNo one lives long enough to learn everything they need to learn starting from scratch. To be successful, we absolutely, positively have to find people who have already paid the price to learn the things that we need to learn to achieve our goals.
Brian TracyAdventuring can be for the ordinary person with ordinary qualities, such as I regard myself.
Edmund HillaryWhen you know a thing, to hold that you know it, and when you do not know a thing, to allow that you do not know it – this is knowledge.
ConfuciusA man only learns in two ways, one by reading, and the other by association with smarter people.
Will RogersI wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartanlike as to put to rout all that was not life.
Henry David ThoreauWorking conditions for me have always been those of the monastic life: solitude and frugality. Except for frugality, they are contrary to my nature, so much so that work is a violence I do to myself.
Albert CamusOne of the interesting things about having little musical knowledge is that you generate surprising results sometimes; you move to places you wouldn’t if you knew better.
Brian EnoLearning without thought is labor lost; thought without learning is perilous.
ConfuciusThere is nothing which can better deserve your patronage, than the promotion of science and literature. Knowledge is in every country the surest basis of public happiness.
