Havana, Cuba, in which city yellow fever had not failed to make its yearly appearance during the past one hundred and forty years... Havana was freed from yellow fever within ninety days. Dr. Walter Reed, 1902

Have you heard or been told that chemical imbalances occur in depression? If so, you have been seriously misinformed.

Have you ever make out time to ask God if there is anything or anybody you need to drop in your life? Are you still holding on to offences? When is the right time to drop it? I am sure once you make this attempt He will show you. I declare that God is going to set some captives free.

Have pity on them all, for it is we who are the real monsters.

Have you ever asked yourself this question "what can God do through me?" The preacher has no platform if the people has no sense of mission.

Hear me, and I will instruct thee; hearken to the thing that I say, and I shall tell thee more.

Having always observed that most of them who constantly took in the weekly Bills of Mortality made little other use of them than to look at the foot how the burials increased or decreased, and among the Casualties what had happened, rare and extraordinary, in the week current; so as they might take the same as a Text to talk upon in the next company, and withal in the Plague-time, how the Sickness increased or decreased, that the Rich might judge of the necessity of their removal, and Trades-men might conjecture what doings they were likely to have in their respective dealings.

He also telephoned the Real Time Computer Complex on the ground floor of the Operations Wing to ask that an additional big I.B.M. computer be brought onto the line.

Have and show motivation to do and learn. That's the key for a good career. Everything else is an extrapolation of that.

Have faith that the results that you are looking for will come from the fruition of your research.

Heartbreak and pain occurs when people love with their heart. It so happens that the heart is not the most vital organ in the body. So when it is 'broken', the body still functions as normal, leaving you alive, but hollow. Next time, love with your brain. So when your lover decides to deceive you, you are not just hollow. You are completely done.

He (Comings) has in the past performed successful energy-converting experiments, creating a ringing resonance by injecting certain frequencies into piezo-electric crystals. When the crystal was in resonance with the plenum of space, the power output rose significantly higher than the input. He concluded that, if allowed politically, such discoveries could guide humankind in building a completely clean energy infrastructure -- resonant technologies that allow us to live in harmony with the universal energy field and the Earth.

Health is wealth but wealth is not health

Hear about the hidden time. Some think the hidden time is yet to come. The Kingdom of God does not come by Observation. It is hidden in the inner dimension.

[Hegel’s] system of nature seemed, at least to natural philosophers, absolutely crazy….Hegel…launched out with particular vehemence and acrimony against the natural philosophers, and especially against Isaac Newton. The philosophers accused the scientific men of narrowness; the scientific men retorted that the philosophers were insane.

Health is wealth but being wealthy does not mean one is healthy.

He fell in love with the way she fell in love with everything besides him.

He had an imagination so excitable that it flirted with the edges of fantasy, which is also something we can try to preserve in ourselves and indulge in our children.

He knew that he was very near achieving the General Temporal Theory that the Ioti wanted so badly for their spaceflight and their prestige. He knew also that he had not achieved it and might never do so. He had never admitted either fact clearly to anyone. Before he left Anarres, he had thought the thing was in his grasp. ... He wasn't quite sure he was ready to publish. There was something not quite right, something that needed a little refining. As he had been working ten years on the theory, it wouldn't hurt to take a little longer, to get it polished perfectly smooth. The little something not quite right kept looking wronger. A little flaw in the reasoning. A big flaw. A crack right through the foundations...The night before he left Anarres he had burned every paper he had on the General Theory. He had come to Urras with nothing. For half a year he had, in their terms, been bluffing them. Or had he been bluffing himself?

Heisenberg and Bohr and Einstein strike me as being like gifted retriever dogs. Off they go, not just for an afternoon, but for ten years; they come back exhausted and triumphant and drop at your feet... a vole. It's a remarkable thing in its way, a vole—intricate, beautiful really, marvellous. But does it... Does it help? Does it move the matter on? When you ask a question that you'd actually like to know the answer to—what was there before the Big Bang, for instance, or what lies beyond the expanding universe, why does life have this inbuilt absurdity, this non sequitur of death—they say that your question can't be answered, because the terms in which you've put it are logically unsound. What you must do, you see, is ask vole questions. Vole is—as we have agreed—the answer; so it follows that your questions must therefore all be vole-related.

He is a unicorn. I want to gently capture him and bring him back to my lab for research.

He leaned into Le Voir’s face with the calliper and breathed on him, holding forth on this new science of which calibration was the test; these measurements would describe classes of being and we who had provided the parameters would be fit within them. To hear him tell it, this classification of species was the hope of Man.

Hell, no. A church is the one thing we don't have. Physics is the religion around here. Use the Lord's name in vain all you like,' he laughed, 'just don't slander any quarks or mesons.

Hello high altitude astronomy, goodbye health.

He pointed to another number, changing as rapidly as the first, but on a lower trajectory; it rose to a high of 8.79 rem per hour. Several lifetimes of dentists’ X-rays, to be sure; but the radiation outside the storm shelter would have been a lethal dose, so they were getting off lightly. Still, the amount flying through the rest of the ship! Billions of particles were penetrating the ship and colliding with the atoms of water and metal they were huddled behind; hundreds of millions were flying between these atoms and then through the atoms of their bodies, touching nothing, as if they were no more than ghosts. Still, thousands were striking atoms of flesh and bone. Most of those collisions were harmless; but in all those thousands, there were in all probability one or two (or three?) in which a chromosome strand was taking a hit, and kinking in the wrong way: and there it was. Tumor initiation, begun with just that typo in the book of the self. And years later, unless the victim's DNA luckily repaired itself, the tumor promotion that was a more or less unavoidable part of living would have its effect, and there would appear a bloom of Something Else inside: cancer. Leukemia, most likely; and, most likely, death.

He laid the foundation of a universal government. His law was one for all. Equal justice and love for everyone.

...Heisenberg removed the conceit that the workings of Nature should necessarily accord with common sense.

Her feelings for Jeremy were like Schrodinger’s Crush. As long as she didn’t open the box, their relationship existed in a state of quantum superposition: both possible and impossible at the same time.

He rejoices in the reason conferred on mankind but mistrusts the shifting sands of man's ingenuity.

Here is the recipe to blow something up: a Pyrex bowl; potassium chloride—found at health food stores, as a salt substitute. A hydrometer. Bleach. Take the bleach and pour it into the Pyrex, put it onto a stove burner. Meanwhile, weigh out your potassium chloride and add to the bleach. Check it with the hydrometer and boil until you get a reading of 1.3. Cool to room temperature, and filter out the crystals that form. This is what you will save. [...] You need 56 grams of these reserved crystals. Mix with distilled water. Heat to a boil and cool again, saving the crystals, pure potassium chlorate. Grind these to the consistency of face powder, and heat gently to dry. Melt five parts Vaseline with five parts wax. Dissolve in gasoline and pour this liquid onto 90 parts potassium chlorate crystals in a plastic bowl. Knead. Allow the gasoline to evaporate. Mold into a cube and dip in wax to make it waterproof. This explosive requires a blasting cap of at least a grade A3.

Her statistics were more than a study... For her, Quetelet was the hero as scientist, and the presentation copy of his Physique Sociale is annotated by her on every page. Florence Nightingale believed—and in all the actions of her life acted upon that belief—that the administrator could only be successful if he were guided by statistical knowledge. The legislator—to say nothing of the politician—too often failed for want of this knowledge.

Here’s another example that some overworked mothers might find inspiring. We saw in Chapter 2 that being the one who produces the sperm doesn’t dictate, by universal principle, that parenting is out of the portfolio. However, in the case of the rat (as with most mammals), the balance of trade-offs make it more adaptive for males to leave parenting to the mothers. This might tempt us to take it for granted that males, by virtue of their sex, therefore lack the capacity to care for pups. We might well assume that, through sexual selection, they lost or never acquired the biological capacity to parent: that it isn’t “in” their genes, hormones, or neural circuits. That it isn’t in their male nature. But bear in mind that one reliable feature of a male rat’s developmental system is a female rat that does the child care. So what happens when a scientist, under controlled laboratory conditions, simulates a first-wave feminist rodent movement by placing males in cages with pups but no females? Before too long you will see the male “mothering” the infant, in much the same way that females do. Feminism: 1. Sexual selection: nil.

Here's how to freak out a baby: sit across from the baby, engage with him or her, and then suddenly become still. If this goes on for more than a few seconds, with you looking all corpselike, the baby will become upset.

Here the sky is wrapped in silk. The breathings of so many men and animals, and the smoke of your coal, and the fog, oh, it is too much. The Paris sky is perfect. A man must see clearly, to see something new.

He’s going to kill me,” Peppone murmured, his jaw drooping, “or at least send out the order to have someone take care of me. Well,” with a sigh, “might as well get rid of this body before the others wake up.” He canted his head and mused to himself. “Maybe I should carve it up first.” “At long last,” Bartleby cried, raising his eyes and wringing his hands, “somebody who has no regard for collective conscience and general morality. Oh, happy, happy morning!” “Take care, Peppone,” Danaco laughed, “if you have so little regard for life and the creatural condition, Bartleby will attach himself to you and never leave you for a moment.

He shall rule, whom they look not for that dwell upon the earth, and the fowls shall take their flight away together:

He was a fast and proficient chemist and so was I. The shrink says she doesn't question that. But what every scientist knows—you can't just be proficient; you have to have insight.

He tracks the rise and fall of the glittering darkness thronged with specks and tendrils of luminous secrets. Falling stars crackle in the cold air and prickle his skin. They flash in the corner of his vision where the eye’s discernment of light and shadow is most acute.

He was pale as only one state on Bhast dictated—not lacking color necessarily or vitality, certainly. Fey white was more comparable to a pearl; the color subtle and the luster soft, but still vibrant. In spite of the tragedy that could come with it, it was not a dying state. It was a state of living…sometimes much more brilliantly than people could cope with, including the Fey individuals themselves.

He was following the Earth through its days, drifting with the rhythms of its myriad pulses, seeping through the webs of its life, swelling with its tides, turning with its weight.

He was one of that class of men who, apart from a scientific career in which they may well have proved brilliantly successful, have acquired an entirely different kind of culture, literary or artistic, for which their professional specialisation has no use but by which their conversation profits.

He was the least spiritual of all the monks here, accepting nothing without proof. This skepticism was simultaneously his greatest asset and his greatest impediment.

He was scrupulous about the use of his title because, his investigations being so utterly unscientific, he hoped to borrow an air of respectability, even scholarly authority, from his education.

He who does not cherish life, does not deserve to be among the living. ☥

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.

He's been trying to destroy me, piece by careful piece, while I romanticized every second of it.
