Science Quotes

Arguably the greatest technological triumph of the century has been the public-health system, which is sophisticated preventive and investigative medicine organized around mostly low- and medium-tech equipment; ... fully half of us are alive today because of the improvements.

~ Richard Rhodes

There is a saying in the medical profession 'Inside everytablet is a little bit of poison'. Avoid medications if you can.

~ Steven Magee

The radiation detoxification process exists in nature. It is called: Hibernation.

~ Steven Magee

Humanity shares a common ancestry with all living things on Earth. We often share especially close intimacies with the microbial world. In fact, only a small percentage of the cells in the human body are human at all. Yet, the common biology and biochemistry that unites us also makes us susceptible to contracting and transmitting infectious disease.

~ Brenda Wilmoth Lerner

Men of science offer us health, an obvious benefit; it is only afterwards that we discover that by health, they mean bodily slavery and spiritual tedium.

~ G.k. Chesterton

Human milk is like ice cream, penicillin, and the drug ecstasy all wrapped up in two pretty packages.

~ Florence Williams

[It] is hardly possible to maintain seriously that the evil done by science is not altogether outweighed by the good. For example, if ten million lives were lost in every war, the net effect of science would still have been to increase the average length of life.

~ G.h. Hardy

Moreover, the sciences are monuments devoted to the public good; each citizen owes to them a tribute proportional to his talents. While the great men, carried to the summit of the edifice, draw and put up the higher floors, the ordinary artists scattered in the lower floors, or hidden in the obscurity of the foundations, must only seek to improve what cleverer hands have created.

~ Charles-Augustin De Coulomb

If then the question is put to me whether I would rather have a miserable ape for a grandfather or a man highly endowed by nature and possessed of great means of influence and yet employs these faculties and that influence for the mere purpose of introducing ridicule into a grave scientific discussion, I unhesitatingly affirm my preference for the ape.

~ Thomas Henry Huxley

When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Silurian system was deposited, they seem to me to become ennobled.

~ Charles Darwin

There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

~ Charles Darwin

Many evolutionists today... continually promote the idea that 'Big Change = Small Change x Millions of Years'. This is logical fallacy... It is akin to saying because a cow can jump over a fence, it it only a matter of time and practice for it to jump over the moon.

~ Dr. Donald Batten

Deteriorated science is a cult, so is imitative or deteriorated Sufism.

~ Idries Shah

The lesson of every extinction, says the Smithsonian’s Doug Erwin, is that we can’t predict what the world will be 5 million years later by looking at the survivors.There will be plenty of surprises. Let’s face it: who would’ve predicted the existence of turtles? Who would ever have imagined that an organism would essentially turn itself inside out, pulling its shoulder girdle inside its ribs to form a carapace? If turtles didn’t exist, no vertebrate biologist would’ve suggested that anything would do that: he’d have been laughed out of town. The only real prediction you can make is that life will go on. And that it will be interesting.

~ Alan Weisman

it is high time we stop using the term “theory” while mentioning Evolution. The term “theory” somehow makes some people think of Evolution as an unproven “hypothesis”. Theory of Evolution is an incontrovertible fact of science. It is not a fictitious story like Creationism. It’s a hard reality. It is the bed-rock of Biology. Defying evolution means defying one’s own existence as a human being.

~ Abhijit Naskar

If a functional gene becomes a pseudogene, its product will no longer be available to the biochemical pathways in which it formerly participated. The transformation of a gene to a pseudogene will not have catastrophic consequences if the biochemical pathways in which its product formerly participated are redundantly complex—other products can take over the role of the missing product. Perhaps not as efficiently, but efficiency is something that can be improved by selection. In this way, redundant scaffolding can be reduced, ultimately to the point where a system or pathway is irreducibly complex.

~ Niall Shanks

Science can neither prove nor disprove Scripture, it can hope only to begin to understand it.

~ Ron Brackin

The story of evolution is more dramatic, more compelling, more intricate than any creation myth. Yet like any creation myth, it is a tale of transformations, of sudden and spectacular changes, eruptions of innovation that transfigured our planet, overwriting past revolutions with new layers of complexity. The tranquil beauty of our planet from space belies the real history of this place, full of strife and ingenuity and change. How ironic that our own petty squabbles reflect our planet's turbulent past, and that we alone, despoilers of the Earth, can rise above it to see the beautiful unity of the whole.

~ Nick Lane

Every question leads to new answers, new discoveries, and new smarter questions.

~ Bill Nye

The best scientists can do is fail to disprove things while pointing to how hard they tried

~ Richard Dawkins

All life evolves by the differential survival of replicating entities

~ Richard Dawkins

What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology which are likely to have similar universal validity? When astronauts voyage to distant planets and look for life, they can expect to find creatures too strange and unearthly for us to imagine. But is there anything which must be true of all life, wherever it is found, and whatever the basis of its chemistry? If forms of life exist whose chemistry is based on silicon rather than carbon, or ammonia rather than water, if creatures are discovered which boil to death at -100 degrees centigrade, if a form of life is found which is not based on chemistry at all, but on electronic reverberating circuits, will there still be any general principle which is true of all life? Obviously I do not know but, if I had to bet, I would put my money on one fundamental principle. This is the law that all life evolves by the differential survival of replicating entities. The gene, the DNA molecule, happens to be the replicating entity which prevails on our own planet. There may be others. If there are, provided certain conditions are met, they will almost inevitably tend to become the basis for an evolutionary process.

~ Richard Dawkins

Man is the result of a purposeless and natural process that did not have him in mind.

~ George Gaylord Simpson

The essential quality that an entity needs, if it is to become an effective gene vehicle, is this. It must have an impartial exit channel into the future, for all the genes inside it. This is true of an individual wolf. The channel is the thin stream of sperms, or eggs, which it manufactures by meiosis. It is not true of the pack of wolves. Genes have something to gain from selfishly promoting the welfare of their own individual bodies, at the expense of other genes in the wolf pack. A bee-hive, when it swarms, appears to reproduce by broad-fronted budding, like a wolf pack. But if we look more carefully we find that, as far as the genes are concerned, their destiny is largely shared. The future of the genes in the swarm is, at least to a large extent, lodged in the ovaries of one queen. This is why—it is just another way of expressing the message of earlier chapters—the bee colony looks and behaves like a truly integrated single vehicle.

~ Richard Dawkins

If about a dozen genera of birds had become extinct or were unknown, who would have ventured to have surmised that birds might have existed which used their wings solely as flappers, like the logger-headed duck (Micropterus of Eyton); as fins in the water and front legs on the land, like the penguin; as sails, like the ostrich; and functionally for no purpose, like the Apteryx. Yet the structure of each of these birds is good for it, under the conditions of life to which it is exposed, for each has to live by a struggle; but it is not necessarily the best possible under all possible conditions. It must not be inferred from these remarks that any of the grades of wing-structure here alluded to, which perhaps may all have resulted from disuse, indicate the natural steps by which birds have acquired their perfect power of flight; but they serve, at least, to show what diversified means of transition are possible.

~ Charles Darwin

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.

~ Nick Lane

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.

~ Carl Sagan

The myosin in our own skeletal muscles is more closely related to the myosin driving the flight muscles of that irritating housefly buzzing around your head than it is to the myosin in the muscles of your own sphincters

~ Nick Lane

All social animals, including people, live under constant pressure from two competing interests: protecting themselves from others and aligning themselves with others. When these two interests are balanced, the result is dynamic social homeostasis.

~ Mystery

It is high time that we grew up and left the Garden. We are indeed Eden’s children, yet it is time to place Genesis alongside the geocentric myth in the basket of stories that once, in a world of intellectual naivete, made helpful sense. As we walk through the gates, aware of the dazzling richness of the genuine biological world, there might even be a smile on the Creator’s face — that at long last His creatures have learned enough to understand His world as it truly is.

~ Kenneth R. Miller

...I suspect everyone there can reason along the lines I described...It's just that when it comes to evolution, and especially to the related realization that we are all pretty small bits of the universe, it seems as though Ham and his followers just can't handle the truth. They throw aside their common sense and cling to the hope that there's something that makes it okay to *not* think for themselves.The irony is, in the process they are walking away from our ability to understand who we are, where we came from, and how we fit into a cosmos...If there is something divine in our nature, something that sets humans apart from all creatures, surely our ability to reason is a key part of it. The irony is, in the process they are walking away from our ability to understand who we are, where we came from, and how we fit into a cosmos...If there is something divine in our nature, something that sets humans apart from all creatures, surely our ability to reason is a key part of it.

~ Bill Nye

However life started, once established, it persisted for over 3.5 billion years and evolved from microbial slime to the sophistication of human civilization.

~ David C. Catling

The secrets of evolution, are time and death. There's an unbroken thread that stretches from those first cells to us.

~ Carl Sagan

Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.

~ James D. Watson

Alternatively, anyone who favors Intelligent Design in lieu of evolution might pause to wonder why God devoted so much of His intelligence to designing malarial parasites.

~ David Quammen

Ending up with that gigantic outsized brain must have taken some sort of runaway evolutionary process, something that would push and push without limits.And today's scientists had a pretty good guess at what that runaway evolutionary process had been.Harry had once read a famous book called Chimpanzee Politics. The book had described how an adult chimpanzee named Luit had confronted the aging alpha, Yeroen, with the help of a young, recently matured chimpanzee named Nikkie. Nikkie had not intervened directly in the fights between Luit and Yeroen, but had prevented Yeroen's other supporters in the tribe from coming to his aid, distracting them whenever a confrontation developed between Luit and Yeroen. And in time Luit had won, and become the new alpha, with Nikkie as the second most powerful......though it hadn't taken very long after that for Nikkie to form an alliance with the defeated Yeroen, overthrow Luit, and become the new new alpha.It really made you appreciate what millions of years of hominids trying to outwit each other - an evolutionary arms race without limit - had led to in the way of increased mental capacity.'Cause, y'know, a human would have totally seen that one coming.

~ Eliezer Yudkowsky

The practice of that which is ethically best—what we call goodness or virtue—involves a course of conduct which, in all respects, is opposed to that which leads to success in the cosmic struggle for existence. In place of ruthless self-assertion it demands self-restraint; in place of thrusting aside, or treading down, all competitors, it requires that the individual shall not merely respect, but shall help his fellows... It repudiates the gladiatorial theory of existence... Laws and moral precepts are directed to the end of curbing the cosmic process.

~ Thomas Henry Huxley

Social intelligence was therefore always at a high premium. A sharp sense of empathy can make a huge difference, and with it in an ability to manipulate, to gain cooperation, and to deceive.

~ Edward O. Wilson

Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.

~ Donald J. Cram

What happens to the world when science stops evolving?
