[Cinema]… obeys the laws of the mind rather than those of the outer world.

The mortal enemies of man are not his fellows of another continent or race; they are the aspects of the physical world which limit or challenge his control, the disease germs that attack him and his domesticated plants and animals, and the insects that carry many of these germs as well as working notable direct injury. This is not the age of man, however great his superiority in size and intelligence; it is literally the age of insects.

Warder C. Allee

And so from then onwards, Daniel understood that the point of this grueling sundial project was not merely to plot the curve but to understand why each curve was shaped as it was. To put it another way, Isaac wanted to be able to walk up to a blank wall on a cloudy day, stab a gnomom into it, and draw all of the curves simply by knowing where shadow would pass. This was the same thing as knowing where the sun would be in the sky and that was the same as knowing where the Earth was in its circuit around the sun, and in its daily rotation. Though as months went on, Daniel understood that Isaac wanted to be able to do the same thing even if the blank wall happened to be situated on, say, the moon that Christiaan Huygens had lately discovered revolving around Saturn. Exactly how this might be accomplished was a question with ramifications that extended into such fields as would Isaac, and Daniel for that matter, be thrown out of Trinity College? Were the Earth and all the works of man nearing the end of a long, relentless decay that had begun with the expulsion from Eden, and that would very soon culminate in the apocalypse? Or might things actually be getting better, with the promise of continuing to do so? Did people have souls? Did they have free will?

Neal Stephenson

...any object functioning within the physical laws of any particular universe does not have free will ... In terms of human beings, all behavior and cognition cannot appear out of thin air. Behavior and cognition must be the result of prior causes. This is because our brains obey the same laws of a cause and effect physical universe just like any other physical object. All events that occur in the universe are caused by antecedent events.Quantum indeterminacy, which maintains that the state of a system does not determine a unique collection of values for all its measurable properties, is not a valid argument for free will and has been used incorrectly to justify beliefs of independent decision-making. Logically speaking, notions of randomness and indeterminism are actually additional arguments against free will. All events that occur at random in the universe are, by definition, not caused by antecedent events. Or to say it a different way, any random event cannot also be a willed event.By the process of elimination, events that are “willed freely” are events that are neither determined nor random. In other words, in all likelihood events that are “willed freely” are events that simply do not exist.

Mark J. Solomon

Freedom of will is born from the neurons. And that freedom allows you to sometimes make even the worst decisions ever in your life. And by making the worst decision, you simply learn what would be the better decision in future.

Abhijit Naskar

Running overtime is the one unforgivable error a lecturer can make. After fifty minutes (one microcentury as von Neumann used to say) everybody's attention will turn elsewhere.

Gian-Carlo Rota

...a wealth of information creates a poverty of attention...

Herbert A. Simon

But if the Bible is not everywhere literally true, which parts are divinely inspired and which are merely fallible and human? As soon as we admit that there are scriptural mistakes (or concessions to the ignorance of the times), then how can the Bible be an inerrant guide to ethics and morals? Might sects and individuals now accept as authentic the parts of the Bible they like, and reject those that are inconvenient or burdensome?

Carl Sagan

In reality, time doesn't pass; we pass. Time itself is invariant. It just is. Therefore, past and future aren't separate locations, the way New York and Paris are separate locations. And since the past isn't a location, you can't travel to it.

Michael Crichton

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

Dan Brown

If you wish to see God; look people in the eye, listen to them, and see how they treat other people.

stacy snapp killian: StacyK

Futurists and common sense concur that a substantial change, worldwide, in life-style and moral guidelines will soon become an absolute necessity.

Roger Wolcott Sperry

In its encounter with Nature, science invariably elicits a sense of reverence and awe. The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos. And the cumulative worldwide build-up of knowledge over time converts science into something only a little short of a trans-national, trans-generational meta-mind.

Carl Sagan

Love is that micro-moment of warmth and connection that you share with another living being

Barbara L. Fredrickson

Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.

Thomas Hunt Morgan

Chloroplasts bear chlorophyll; they give the green world its color, and they carry out the business of photosynthesis. Around the inside perimeter of each gigantic cell trailed a continuous loop of these bright green dots. They spun . . . they pulsed, pressed, and thronged . . . they shone, they swarmed in ever-shifting files around and around the edge of the cell; they wandered, they charged, they milled, raced . . . they flowed and trooped greenly . . . All the green in the planted world consists of these whole, rounded chloroplasts . . . If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood, the streaming red dots in the goldfish’s tail.

Annie Dillard

My laboratory is interested in the related challenges of understanding the origin of life on the early earth, and constructing synthetic cellular life in the laboratory. Focusing on artificial life frees us to explore novel chemical systems, but what we learn from these systems helps us to understand possible pathways leading to the origin of life. Our basic design for a synthetic cell involves the encapsulation of a spontaneously replicating nucleic acid, which acts as the genetic material, within a spontaneously replicating membrane vesicle, which provides spatial localization. We are using chemical synthesis to make nucleic acids with modified nucleobases and sugar-phosphate backbones.

Jack W. Szostak

The body is merely an evolutionary vehicle for the gene

Matt Ridley

We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.

Charles Darwin

The cell, this elementary keystone of living nature, is far from being a peculiar chemical giant molecule or even a living protein and as such is not likely to fall prey to the field of an advanced chemistry. The cell is itself an organism, constituted of many small units of life.

Oscar Hertwig

If the results of the present study on the chemical nature of the transforming principle are confirmed, then nucleic acids must be regarded as possessing biological specificity the chemical basis of which is as yet undetermined.

Oswald Theodore Avery

A nutritive centre, anatomically considered, is merely a cell, the nucleus of which is the permanent source of successive broods of young cells, which from time to time fill the cavity of their parent, and carrying with them the cell wall of the parent, pass off in certain directions, and under various forms, according to the texture or organ of which their parent forms a part.

John Goodsir

Of the contributions made during the essayist period three call for notice: Weismann deserves mention for his useful work in asking for the proof that "acquired characters" or, to speak more precisely, parental experience can really be transmitted to the offspring. The ocurrence of progressive adaptation by transmission of effects of use had seemed so natural to Darwin and his contemporaries that no proof of the physiological reality of the henomenon was thought necessary. Weismann's challenge revealed the utter inadequacy of the evidence on which the beliefs were based. They are doubtless isolated observations which may be interpreted as favouring the belief in these transmissions, but such meagre indications as exist are by general consent admitted to be too slight to be of much assistance in the attempt to understand how the more complex adaptive mechanisms arose.

William Bateson

Insects are major players in nature's recycling effort, and in nature a corpse is simply organic matter to be recycled. Left to its own devices, nature quickly populates a corpse with a diverse community of organisms, all dedicated to reducing the body to its basic components.

M. Lee Goff

I am above the forest region, amongst grand rocks & such a torrent as you see in Salvator Rosa's paintings vegetation all a scrub of rhodos. with Pines below me as thick & bad to get through as our Fuegian Fagi on the hill tops, & except the towering peaks of P. S. [perpetual snow] that, here shoot up on all hands there is little difference in the mt scenery—here however the blaze of Rhod. flowers and various colored jungle proclaims a differently constituted region in a naturalist's eye & twenty species here, to one there, always are asking me the vexed question, where do we come from?[Letter to Charles Darwin 24 Jun 1849]

Joseph Dalton Hooker

In describing a protein it is now common to distinguish the primary, secondary and tertiary structures. The primary structure is simply the order, or sequence, of the amino-acid residues along the polypeptide chains. This was first determined by [Frederick] Sanger using chemical techniques for the protein insulin, and has since been elucidated for a number of peptides and, in part, for one or two other small proteins. The secondary structure is the type of folding, coiling or puckering adopted by the polypeptide chain: the a-helix structure and the pleated sheet are examples. Secondary structure has been assigned in broad outline to a number of librous proteins such as silk, keratin and collagen; but we are ignorant of the nature of the secondary structure of any globular protein. True, there is suggestive evidence, though as yet no proof, that a-helices occur in globular proteins, to an extent which is difficult to gauge quantitatively in any particular case. The tertiary structure is the way in which the folded or coiled polypeptide chains are disposed to form the protein molecule as a three-dimensional object, in space. The chemical and physical properties of a protein cannot be fully interpreted until all three levels of structure are understood, for these properties depend on the spatial relationships between the amino-acids, and these in turn depend on the tertiary and secondary structures as much as on the primary. Only X-ray diffraction methods seem capable, even in principle, of unravelling the tertiary and secondary structures.[Co-author with G. Bodo, H. M. Dintzis, R. G. Parrish, H. Wyckoff, and D. C. Phillips]

John Kendrew

The deviation of man from the state in which he was originally placed by nature seems to have proved to him a prolific source of diseases. From the love of splendour, from the indulgences of luxury, and from his fondness for amusement he has familiarised himself with a great number of animals, which may not originally have been intended for his associates.The wolf, disarmed of ferocity, is now pillowed in the lady's lap. The cat, the little tiger of our island, whose natural home is the forest, is equally domesticated and caressed. The cow, the hog, the sheep, and the horse, are all, for a variety of purposes, brought under his care and dominion.

Edward Jenner

Branches or types are characterized by the plan of their structure,Classes, by the manner in which that plan is executed, as far as ways and means are concerned, Orders, by the degrees of complication of that structure, Families, by their form, as far as determined by structure, Genera, by the details of the execution in special parts, andSpecies, by the relations of individuals to one another and to the world in which they live, as well as by the proportions of their parts, their ornamentation, etc.

Louis Agassiz

The same few dozen organic molecules are used over and over again in biology for the widest variety of functions.

Carl Sagan

The extracellular genesis of cells in animals seemed to me, ever since the publication of the cell theory [of Schwann], just as unlikely as the spontaneous generation of organisms. These doubts produced my observations on the multiplication of blood cells by division in bird and mammalian embryos and on the division of muscle bundles in frog larvae. Since then I have continued these observations in frog larvae, where it is possible to follow the history of tissues back to segmentation.

Robert Remak

The cause of nutrition and growth resides not in the organism as a whole but in the separate elementary parts—the cells.

Theodor Schwann

The principal result of my investigation is that a uniform developmental principle controls the individual elementary units of all organisms, analogous to the finding that crystals are formed by the same laws in spite of the diversity of their forms.

Theodor Schwann

Life is not found in atoms or molecules or genes as such, but in organization; not in symbiosis but in synthesis.

Edwin Grant Conklin

A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.

Frederick Sanger

I may finally call attention to the probability that the association of paternal and maternal chromosomes in pairs and their subsequent separation during the reducing division as indicated above may constitute the physical basis of the Mendelian law of heredity.

Walter S. Sutton

For it is not cell nuclei, not even individual chromosomes, but certain parts of certain chromosomes from certain cells that must be isolated and collected in enormous quantities for analysis; that would be the precondition for placing the chemist in such a position as would allow him to analyse [the hereditary material] more minutely than [can] the morphologists ... For the morphology of the nucleus has reference at the very least to the gearing of the clock, but at best the chemistry of the nucleus refers only to the metal from which the gears are formed.

Theodor Boveri

The science of genetics is in a transition period, becoming an exact science just as the chemistry in the times of Lavoisier, who made the balance an indispensable implement in chemical research.

Wilhelm Johannsen

Biogeography typically trumps taxonomy and anticipates molecular phylogeny

Dennis McCarthy

It is our alarming misfortune that so primitive a science has armed itself with the most modern and terrible weapons

Rachel Carson

God is an energy, rather than an anthropomorphic being, and God's language is biology. Red blood cells, the principle of magnetic attraction, neurological synapse: each is a miracle, and in each is the presence and flow of God.

Guillermo del Toro

People, as curious primates, dote on concrete objects that can be seen and fondled. God dwells among the details, not in the realm of pure generality. We must tackle and grasp the larger, encompassing themes of our universe, but we make our best approach through small curiosities that rivet our attention - all those pretty pebbles on the shoreline of knowledge. For the ocean of truth washes over the pebbles with every wave, and they rattle and clink with the most wondrous din.

Stephen Jay Gould

It seems that all eukaryotic cells either have, or once had (and then lost) mitochondria. In other words, possession of mitochondria is a sine qua non of the eukaryotic condition

Nick Lane

From a biology point of view, the purpose of humanity is to ensure his survival by expanding his domain into the stars.

Osman Doluca

Wilson (1975) defines biological communication relatively broadly as 'the action on the part of one organism (or cell) that alters the probability pattern of behavior in another organism (or cell) in a fashion adaptive to either one or both of the participants.

Robert K. Vander Meer Michael D. Breed et al.

George Gey paid his way through a biology degree at the University of Pittsburgh by working as a carpenter and mason, and he could make nearly anything for cheap or free. During his second year in medical school, he rigged a microscope with a time-lapse motion picture camera to capture live cells on film. It was a Frankensteinish mishmash of microscope parts, glass, and 16-millimeter camera equipment from who knows where, plus metal scraps, and an old motor from Shapiro’s junkyard. He built it in a hole he’d blasted in the foundation of Hopkins, right below the morgue, its base entirely underground and surrounded by a thick wall of cork to keep it from jiggling when streetcars passed. At night, a Lithuanian lab assistant slept next to the camera on a cot, listening to its constant tick, making sure it stayed stable through the night, waking every hour to refocus it. With that camera, Gey and his mentor, Warren Lewis, filmed the growth of cells, a process so slow - like the growth of a flower - the naked eye couldn’t see it. They played the film at high speed so they could watch cell division on the screen in one smooth motion, like a story unfolding in a flip book.

skloot

It is also only in humans that aggression may be used to commit crimes, to enslave others or compel acquiescence to religious or ideological doctrine, or to pursue wars of national interest. At the individual level, men are universally more aggressive than women, and rates of aggressive confrontation are greatest among those who are young, poor, or unmarried. Cultural factors moderate human aggression as well, with men's heightened sensitivity to signs of disrespect, challenge, or threat spawning a high frequency of confrontational violence in so-called “cultures of honor”.

Randy J. Nelson

As the physicist Paul Davies puts it, 'If everything needs everything else, how did the communities of molecules ever arise in the first place?' It is rather as if all the ingredients in your kitchen somehow got together and baked themselves into a cake - but a cake that could moreover divide when necessary to produce more cakes. It is little wonder that we call it the miracle of life. It is also little wonder that we have barely begun to understand it.

Bill Bryson

No, Carolyn, you can’t petition PETA to get a waiver from dissecting the frog. The frog’s already dead. It donated itself to science. Don’t let its sacrifice be in vain. -Brandon

Abigail Roux

It wasn’t that we started to look at things because there was now a mechanism by which to see them. There first had to be a will to see, buried somewhere inside living things. Without it, the mechanism would never have taken shape.

Kōji Suzuki

The foreign policy aim of ants can be summed up as follows: restless aggression, territorial conquest, and genocidal annihilation of neighboring colonies whenever possible. If ants had nuclear weapons, they would probably end the world in a week.

Bert Hölldobler

In the ensuing chapters, we will look in some detail at particular manifestations of the modern scientific ideology and the false paths down which it has led us. We will consider how biological determinism has been used to explain and justify inequalities within and between societies and to claim that those inequalities can never be changed. We will see how a theory of human nature has been developed using Darwin's theory of evolution by natural selection to claim that social organization is also unchangeable because it is natural. We will see how problems of health and disease have been located within the individual so that the individual becomes a problem for society to cope with rather than society becoming a problem for the individual. And we will see how simple economic relationships masquerading as facts of nature can drive the entire direction of biological research and technology.

Richard C. Lewontin

Our terminal decline into old age and death stems from the fine print of the contract that we signed with our mitochondria two billion years ago.

Nick Lane

Everything can't be explained by some general biological phrase.

Nella Larsen

The inventor...looks upon the world and is not contented with things as they are. He wants to improve whatever he sees, he wants to benefit the world; he is haunted by an idea.

Alexander Graham Bell

Natural science is founded on minute critical views of the general order of events taking place upon our globe, corrected, enlarged, or exalted by experiments, in which the agents concerned are placed under new circumstances, and their diversified properties separately examined. The body of natural science, then, consists of facts; is analogy,—the relation of resemblance of facts by which its different parts are connected, arranged, and employed, either for popular use, or for new speculative improvements.

Humphry Davy

Is it not time to cry that the blind shall see, the deaf hear, the lame walk? But that which fanaticism formerly promised to its elect, science now accomplishes for all men.

Gustave Flaubert

Nature intended me for the tranquil pursuits of science, by rendering them my supreme delight. But the enormities of the times in which I have lived, have forced me to take a part in resisting them, and to commit myself on the boisterous ocean of political passions.

Thomas Jefferson

I took a glass retort, capable of containing eight ounces of water, and distilled fuming spirit of nitre according to the usual method. In the beginning the acid passed over red, then it became colourless, and lastly again all red: no sooner did this happen, then I took away the receiver; and tied to the mouth of the retort a bladder emptied of air, which I had moistened in its inside with milk of lime lac calcis, (i.e. lime-water, containing more quicklime than water can dissolve) to prevent its being corroded by the acid. Then I continued the distillation, and the bladder gradually expanded. Here-upon I left every thing to cool, tied up the bladder, and took it off from the mouth of the retort.— I filled a ten-ounce glass with this air and put a small burning candle into it; when immediately the candle burnt with a large flame, of so vivid a light that it dazzled the eyes. I mixed one part of this air with three parts of air, wherein fire would not burn; and this mixture afforded air, in every respect familiar to the common sort. Since this air is absolutely necessary for the generation of fire, and makes about one-third of our common air, I shall henceforth, for shortness sake call it empyreal air, [literally fire-air] the air which is unserviceable for the fiery phenomenon, and which makes abut two-thirds of common air, I shall for the future call foul air [literally corrupted air].

Carl Wilhelm Scheele

As to Science, she has never sought to ally herself to civil power. She has never attempted to throw odium or inflict social ruin on any human being. She has never subjected anyone to mental torment, physical torture, least of all to death, for the purpose of upholding or promoting her ideas. She presents herself unstained by cruelties and crimes. But in the Vatican—we have only to recall the Inquisition—the hands that are now raised in appeals to the 'Most Merciful' are crimsoned. They have been steeped in blood!

John William Draper

Why two (or whole groups) of people can come up with the same story or idea at the same time, even when across the world from each-other:"A field is a region of influence, where a force will influence objects at a distance with nothing in between. We and our universe live in a Quantum sea of light. Scientists have found that the real currency of the universe is an exchange of energy. Life radiates light, even when grown in the dark. Creation takes place amidst a background sea of energy, which metaphysics might call the Force, and scientists call the "Field." (Officially the Zero Point Field) There is no empty space, even the darkest empty space is actually a cauldron of energies. Matter is simply concentrations of this energy (particles are just little knots of energy.) All life is energy (light) interacting. The universe is self-regenreating and eternal, constantly refreshing itself and in touch with every other part of itself instantaneously. Everything in it is giving, exchanging and interacting with energy, coming in and out of existence at every level. The self has a field of influence on the world and visa versa based on this energy.Biology has more and more been determined a quantum process, and consciousness as well, functions at the quantum level (connected to a universe of energy that underlies and connects everything). Scientist Walter Schempp's showed that long and short term memory is stored not in our brain but in this "Field" of energy or light that pervades and creates the universe and world we live in.A number of scientists since him would go on to argue that the brain is simply the retrieval and read-out mechanism of the ultimate storage medium - the Field. Associates from Japan would hypothesize that what we think of as memory is simply a coherent emission of signals from the "Field," and that longer memories are a structured grouping of this wave information. If this were true, it would explain why one tiny association often triggers a riot of sights, sounds and smells. It would also explain why, with long-term memory in particular, recall is instantaneous and doesn't require any scanning mechanism to sift through years and years of memory.If they are correct, our brain is not a storage medium but a receiving mechanism in every sense, and memory is simply a distant cousin of perception.Some scientists went as far as to suggest that all of our higher cognitive processes result from an interaction with the Field. This kind of constant interaction might account for intuition or creativity - and how ideas come to us in bursts of insight, sometimes in fragments but often as a miraculous whole. An intuitive leap might simply be a sudden coalescence of coherence in the Field.The fact that the human body was exchanging information with a mutable field of quantum fluctuation suggested something profound about the world. It hinted at human capabilities for knowledge and communication far deeper and more extended than we presently understand. It also blurred the boundary lines of our individuality - our very sense of separateness. If living things boil down to charged particles interacting with a Field and sending out and receiving quantum information, where did we end and the rest of the world began? Where was consciousness-encased inside our bodies or out there in the Field?Indeed, there was no more 'out there' if we and the rest of the world were so intrinsically interconnected. In ignoring the effect of the "Field" modern physicists set mankind back, by eliminating the possibility of interconnectedness and obscuring a scientific explanation for many kinds of miracles. In re-normalizing their equations (to leave this part out) what they'd been doing was a little like subtracting God.
