He wondered if somewhere far off, defying the laws of science, Mitch's two screams were still echoing, if those vibrations had traveled into space, if they moved on and on like rays in a light-year. There might be other forms of life who were receiving the noise and trying to interpret the tones.

He who wishes to explain Generation must take for his theme the organic body and its constituent parts, and philosophize about them; he must show how these parts originated, and how they came to be in that relation in which they stand to each other. But he who learns to know a thing not only from its phenomena, but also its reasons and causes; and who, therefore, not by the phenomena merely, but by these also, is compelled to say: 'The thing must be so, and it cannot be otherwise; it is necessarily of such a character; it must have such qualities; it is impossible for it to possess others'—understands the thing not only historically but truly philosophically, and he has a philosophic knowledge of it. Our own Theory of Generation is to be such a philosphic comprehension of an organic body, a very different one from one merely historical. (1764)

He wrested the world's whereabouts from the stars, and locked the secret in a pocket watch.

Hey,” Watney said over the radio, “I've got an idea.” “Of course you do,” Lewis said. “What do you got?” “I could find something sharp in here and poke a hole in the glove of my EVA suit. I could use the escaping air as a thruster and fly my way to you. The source of thrust would be on my arm, so I'd be able to direct it pretty easily.” “How does he come up with this shit?” Martinez interjected. “Hmm,” Lewis said. “Could you get 42 meters per second that way?” “No idea,” Watney said. “I can't see you having any control if you did that,” Lewis said. “You'd be eyeballing the intercept and using a thrust vector you can barely control.” “I admit it's fatally dangerous,” Watney said. “But consider this: I'd get to fly around like Iron Man.” “We'll keep working on ideas,” Lewis said. “Iron Man, Commander. Iron Man.

His entire presence was like gravity, impossible to forget, possible to believe in, a theory merged into a law.

His most famous (and possibly apocryphal) mishap involved an operation during which he worked so rapidly that he took off three of his assistant's fingers and, while switching blades, slashed a spectator's coat. Both the assistant and the patient died later of gangrene, and the unfortunate bystander expired on the spot from fright. It is the only surgery in history said to have had a 300 percent fatality rate.

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic? We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected.

Historians of technology have asked why no industrial revolution developed in antiquity. The simple answer seems to be that there was no need, that contemporary modes of production and the slave-based economy of the day satisfactorily maintained the status quo. The capitalist idea of profit as a desirable end to pursue was completely foreign to the contemporary mentality. So, too, was the idea that technology on a large scale could or should be harnessed to those ends. An industrial revolution was literally unthinkable in antiquity.

History proves beyond any possibility of doubt that no religion has ever given a stimulus to scientific progress comparable to that of Islam. The encouragement which learning and scientific research received from Islamic theology resulted in the splendid cultural achievements in the days of the Umayyads and Abbasids and the Arab rule in Sicily and Spain. I do not mention this in order that we might boast of those glorious memories at a time when the Islamic world has forsaken its own traditions and reverted to spiritual blindness and intellectual poverty. We have no right, in our present misery, to boast of past glories. But we must realize that it was the negligence of the Muslims and not any deficiency in the teachings of Islam that caused our present decay. Islam has never been a barrier to progress and science. It appreciates the intellectual activities of man to such a degree as to place him above the angels. No other religion ever went so far in asserting the dominance of reason and, consequently, of learning, above all other manifestations of human life.

His work seems to confirm my old axiom: it is useless to try to keep the whole body alive.

Hitherto the conception of chemical transmission at nerve endings and neuronal synapses, originating in Loewi's discovery, and with the extension that the work of my colleagues has been able to give to it, can claim one practical result, in the specific, though alas only short, alleviation of the condition of myasthenia gravis, by eserine and its synthetic analogues.

Hoh, Boy!" Freddy snorted, slapping his palm to his forehead. "I hope you never donate your brain to science. It would set civilization back fifty years.

History repeats itself, in part because the genome repeats itself. And the genome repeats itself, in part because history does. The impulses, ambitions, fantasies, and desires that drive human history are, at least in part, encoded in the human genome. And human history has, in turn, selected genomes that carry these impulses, ambitions, fantasies, and desires. This self-fulfilling circle of logic is responsible for some of the most magnificent and evocative qualities in our species, but also some of the most reprehensible. It is far too much to ask ourselves to escape the orbit of this logic, but recognizing its inherent circularity, and being skeptical of its overreach, might protect the week from the will of the strong, and the 'mutant' from being annihilated by the 'normal'.

Hitler wanted not only to eradicate the Jews; he wanted also to destroy Poland and the Soviet Union as states, exterminate their ruling classes, and kill tens of millions of Slavs (Russians, Ukrainians, Belarusians, Poles).

Hmmm, it is a small pelvis with a very ample sub-pubic angle; at least ninety degrees...the bones are delicate, fine, graceful...hmmm..." With certainty born of profound expertise and his uncanny ability to dialogue with bones, Romano stated his conclusion without touching anything. "It is a woman." (Arturo Romano Pacheco, physical anthropologist)

Homeopathy is the true and very advanced healing science much beyond the scope of current methods of chemical analysis and interpretation.

hoped to prove that science and religion are two totally compatible fields—two different approaches to finding the same truth.

How, and when shall these things come to pass? wherefore are our years few and evil?

How about we be the light of Jesus Christ? There are things we tend to forget when fear becomes the driving force. The world is filled with a lot of questions now; what do we do? Who do we elect? How do we fix this? Some people feel powetless in those ways. Helpless, hopeless, confused, overwhelmed. What do we do? My answer: Stop looking for practical advice "don't be afraid " "those who are with us are more than those who are with them" 2 kings 6:16

How can a three-pound mass of jelly that you can hold in your palm imagine angels, contemplate the meaning of infinity, and even question its own place in the cosmos? Especially awe inspiring is the fact that any single brain, including yours, is made up of atoms that were forged in the hearts of countless, far-flung stars billions of years ago. These particles drifted for eons and light-years until gravity and change brought them together here, now. These atoms now form a conglomerate- your brain- that can not only ponder the very stars that gave it birth but can also think about its own ability to think and wonder about its own ability to wonder. With the arrival of humans, it has been said, the universe has suddenly become conscious of itself. This, truly, it the greatest mystery of all.

How can one look happy when he is contemplating the anomolous Zeeman effect? (Wolfgang Pauli)

How can anyone trust scientists? If new evidence comes along, they change their minds.

How can the creation challenge and control the Creator? Oh mortal man, know that there is an immortal God with an immortal power!

How can you say one thing when your data shows something else. One doesn't know what was on the authors' minds and maybe they interpreted things differently but the sense is that the literature maintains an attitude somewhat like the approach of lawyers. If the jury buys it, it doesn't matter whether or not it's true. In scientific publishing, the jury are the reviewers and the editors. If they are already convinced of the conclusion, if there is no voir dire, you will surely win the case.

How dare they be so arrogant and presume only their medical methods are fit for public consumption, and not those of a more naturalistic and naturopathic approach?

How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. When I think about the ablest students whom I have encountered in my teaching, that is, those who distinguish themselves by their independence of judgment and not merely their quick-wittedness, I can affirm that they had a vigorous interest in epistemology. They happily began discussions about the goals and methods of science, and they showed unequivocally, through their tenacity in defending their views, that the subject seemed important to them. Indeed, one should not be surprised at this.

How did I discover saccharin? Well, it was partly by accident and partly by study. I had worked a long time on the compound radicals and substitution products of coal tar... One evening I was so interested in my laboratory that I forgot about my supper till quite late, and then rushed off for a meal without stopping to wash my hands. I sat down, broke a piece of bread, and put it to my lips. It tasted unspeakably sweet. I did not ask why it was so, probably because I thought it was some cake or sweetmeat. I rinsed my mouth with water, and dried my moustache with my napkin, when, to my surprise the napkin tasted sweeter than the bread. Then I was puzzled. I again raised my goblet, and, as fortune would have it, applied my mouth where my fingers had touched it before. The water seemed syrup. It flashed on me that I was the cause of the singular universal sweetness, and I accordingly tasted the end of my thumb, and found it surpassed any confectionery I had ever eaten. I saw the whole thing at once. I had discovered some coal tar substance which out-sugared sugar. I dropped my dinner, and ran back to the laboratory. There, in my excitement, I tasted the contents of every beaker and evaporating dish on the table.

How does food work? Ultimately, it is a chain leading back to the sun. Plats photosynthesize energy and store it within themselves. Animals eat the plants. Omnivores like humans eat both. At each stage, it is about precious energy from the sun, locked up in different forms.”, FADE by Kailin Gow

How does it feel to be a part of this beautifully ingenious design. I have faith that there is a chosen moment in which my soul will expand infinitely free from time and space. Some may find that foolish but I have reasons for my beliefs that are uniquely my own. There are hundreds of billions of galaxies making up the universe. Earth is only one planet of billions orbiting inside just one of these 500,000 billion or more galaxies. And I myself am one person. One of over seven billion people living on our dynamic little planet. Instead of being diluted by this infinitesimal proportion I accept it as a challenge and I use science to strengthen my spirituality. It provokes curiosity and redefines my view of logical thinking. I believe that existence is based on the exchange of energy and functionality. Energy is expended to carry out varying tasks ensuring the function of an organism. This is evident in every life form and has been the founding principle supporting lifetimes of discoveries. Energy is spent with purpose. I can't help but draw the conclusion that the energy required to create the universe itself was done so for a purpose. You and I were created with a purpose. -Tavia Rahki Smith

How do we change the way science is taught? Ask anybody how many teachers truly made a difference in their life, and you never come up with more than the fingers on one hand. You remember their names, you remember what they did, you remember how they moved in front of the classroom. You know why you remember them? Because they were passionate about the subject. You remember them because they lit a flame within you. They got you excited about a subject you didn't previously care about, because they were excited about it themselves. That's what turns people on to careers in science and engineering and mathematics. That's what we need to promote. Put that in every classroom, and it will change the world.

However high we climb in the pursuit of knowledge we shall still see heights above us, and the more we extend our view, the more conscious we shall be of the immensity which lies beyond.

How do I know anything about the world around me? By the use of my senses. But I can be deceived by my senses, A straight stick looks bent when it is dipped into water. How do I even know that I am awake, that the whole of reality is not a dream? How can I tell it is not a fabric of delusion woven by some malicious cunning demon simply to deceive me? By a process of persistent and comprehensive questioning it is possible to place in doubt the entire fabric of my existence and the world around me, Nothing remains certain. But in the midst of all this there is nevertheless one thing which does remain certain. No matter how deluded I may be in my thoughts about myself and the world, I still know that I am thinking, This alone proves me my existence, In the most famous remark in philosophy, Descartes concludes: 'Cogito ergo sum'-'I think, therefore I am.

However, as I hope to persuade you, there are some interesting connections between science and magic. They share a belief, as one mathematician put it, that what is visible is merely a superficial reality, not the underlying "real reality." They both have origins in a basic urge to make sense of a hostile world so that we may predict or manipulate it to our own ends.

However, I don’t understand why people insist on pitting the concepts of evolution and creation against each other. Why can’t they see that spiritualism and science are one? That bodies evolve and souls evolve and the universe is a fluid place that marries them both in a wonderful package called a human being. What’s wrong with that idea?

However, the real beauty is not in the words themselves, but in the listener that has the power to understand them.

How little we really know about the life all around us. Would we be so cavalier and ruthless with it if we understood it better?

How many times did the sun shine, how many times did the wind howl over the desolate tundras, over the bleak immensity of the Siberian taigas, over the brown deserts where the Earth’s salt shines, over the high peaks capped with silver, over the shivering jungles, over the undulating forests of the tropics! Day after day, through infinite time, the scenery has changed in imperceptible features. Let us smile at the illusion of eternity that appears in these things, and while so many temporary aspects fade away, let us listen to the ancient hymn, the spectacular song of the seas, that has saluted so many chains rising to the light.

How do you quantify love? Can you weigh it, measure it, pin it down with equations? If the sum of all experiences is really just the interaction of a finite soup of chemicals copulating in nerve endings, how did this even dare articulate the infinite? Mathematicians will tell you there are different types of infinities. Some are countable, some are not. We can love someone more and more; we can stop loving. But we can never guess how much all this is. Love has no units.

How long you will live in your dreams? The time is now, it's better to go and follow them..

How strange it was, I thought, that when the tiny though thousandfold beauties of the Earth disappeared and the immeasurable beauty of outer space rose in the distant quiet splendor of light, man and the greatest number of other creatures were supposed to be asleep! Was it because we were only permitted to catch a fleeting glimpse of those great bodies and then only in the mysterious time of a dream world, those great bodies about which man had only the slightest knowledge but perhaps one day would be permitted to examine more closely? Or was it permitted for the great majority of people to gaze at the starry firmament only in brief, sleepless moments so that the splendor wouldn't become mundane, so that the greatness wouldn't be diminished?

How thoroughly the chimps and bonobos have erased the list of purported human distinctions!-self-awareness, language, ideas and their association, reason, trade, play, choice, courage, love and altruism, laughter, concealed ovulation, kissing, face-to-face sex, female orgasm, division of labor, cannibalism, art, music, politics, and featherless bipedalism, besides tool using, tool making, and much else. Philosophers and scientists confidently offer up traits said to be uniquely human, and the apes casually knock them down--toppling the pretension that humans constitute some sort of biological aristocracy among the beings of Earth. Instead, we are more like the nouveau riche, incompletely accommodated to our recent exalted state, insecure about who we are, and trying to put as much distance as possible between us and our humble origins. It's as if our nearest relatives, by their very existence, refute all our explanations and justifications. So as counterweights to human arrogance and pride, it is good for us that there are still apes on Earth.

Human beings are not nearly as coolly rational as we like to think we are. Having set up comfortable planets of belief, we become resistant to altering them, and develop cognitive biases that prevent us from seeing the world with perfect clarity. We aspire to be perfect Bayesian abductors, impartially reasoning to the best explanation - but most often we take new data and squeeze it to fit with our preconceptions.

How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.

How to hang on to that full-body joy I knew I was capable of and still understand it as elegy.

How were they to square the tremendous wealth they accrued with their image of themselves as frugal and virtuous? Easy: just argue that commerce was itself virtuous. To be rich in corrupt old Europe must be a sign of droneishness; but to be rich in fresh young American was the fruit of hard work. The beehive provided Americans with the ideal image for their religion of work.

How would it alter Juliet’s love perception to learn the sea is but a rounded jug of water? Would her sensuous analogy turned simple simile unveil to her the limits of herself? Or would she forget the ocean, that deplorable casket, and turn on the true bottomless tumbler, the only running tap: the sky? It may have lost the title ‘heavens’ when its gods were dethroned, but its infinity reigns. So long as you walk, it reigns. So long as I talk and you listen, there’s a voice and ears to keep it active, moving, and reason to say: look! infinity lives. And when we and the other consciousnesses pass, though it in part dies with us, still it reigns. It will, in a sense, plod on, like a lifeless coffin through its own space, sails set for nothing, unstoppable when trailing its fabric.

Human beings, Lucretius thought, must not drink in the poisonous belief that their souls are only part of the world temporarily and they are heading somewhere else. That belief will only spawn in them a destructive relation to the environment in which they live the only lives they have.

Human beings feel an obligation to have a definate opinion on issues they can never truly know. They need to learn to be satisfied with "I don't know".

Human brains have three layers of programming. Each layer adds a twist or turn to sexual preferences and tendencies. The first layer is genetic progamming from the inherited genes. The second involves environmental influences that impact genes and their expression. The third level deals with the way we "fill in the blanks" as social and cultural beings. This level can become a feedback loop that influences the inherited genes by influencing with whom we choose to have sex.

Humanity is like someone whose outstretched arms are reaching for the stars but whose feet are mired in the mud.
