Almost all the world is natural chemicals, so it really makes you re-think everything. A cup of coffee is filled with chemicals. They've identified a thousand chemicals in a cup of coffee. But we only found 22 that have been tested in animal cancer tests out of this thousand. And of those, 17 are carcinogens. There are ten milligrams of known carcinogens in a cup of coffee and thats more carcinogens than you're likely to get from pesticide residues for a year!
Bruce Ames
You can't have good ideas unless you have lots of ideas.
Linus Pauling
Research is to see what everybody has seen and to think what nobody else has thought.
Albert Szent-Györgyi
When I feel difficulty coming on I switch to another book I'm writing. When I get back to the problem my unconscious has solved it.
Isaac Asimov

Isaac Asimov
I came I saw I concurred.
Irvine H. Page
Nothing interferes with my concentration. You could put on an orgy in my office and I wouldn't look up. Well maybe once.
Isaac Asimov
Our lifetime may be the last that will be lived out in a technological society.
Isaac Asimov
Society is much more easily soothed than one's own conscience.
Isaac Asimov
The laws of history are as absolute as the laws of physics, and if the probabilities of error are greater, it is only because history does not deal with as many humans as physics does atoms, so that individual variations count for more.
Isaac Asimov
It is unclear how much longer people will write on dried and flattened wood. Trees do so much for humans and for our planet that it hardly seems fair to ask them to carry our thoughts as well. From "Life from an RNA World: The Ancestor Within.
Michael Yarus
I think you are wrong, partner Elijah. My briefing on human characteristics here among the people of Earth includes the information that, unlike the men of the Outer Worlds, they are trained from birth to accept authority. Apparently this is the result of your way of living. One man, representing authority firmly enough, was quite sufficient, as I proved. Your own desire for a squad car was only an expression, really, of your almost instinctive wish for superior authority to take responsibility out of your hands. On my own world, I admit that what I did would have been most unjustified.
Isaac Asimov
And now a hundred subjective years had passed in those hundred objective hours and he could no longer clearly visualize the university at all or the life of sad frustration he had been leading there toward the end.
Isaac Asimov
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]

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
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
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
Aimless extension of knowledge, however, which is what I think you really mean by the term curiosity, is merely inefficiency. I am designed to avoid inefficiency.
Isaac Asimov
Mathematicians deal with large numbers sometimes, but never in their income.
Isaac Asimov
There was something ghost-like and insubstantial about gases to these early chemists. They called liquids that turned into gases easily, "spirits." Methyl alcohol, they called "wood spirit"; ethyl alcohol, "wine spirit." Even today, alcoholic beverages are frequently referred to as "spirits." (Modern Arabs, from whose language the word "alcohol" was taken, call ethyl alcohol "spirit" from the English. This is a queer exchange.)
Isaac Asimov
Somewhere on the world was the Emperor's palace, set amid one hundred square miles of natural soil, rainbowed with flowers.
Isaac Asimov
Discovery consists of seeing what everybody has seen and thinking what nobody else has thought.
Albert Szent-Györgyi
[A]n unpleasant nest of nasty, materialistic and aggressive people, careless of the rights of others, imperfectly democratic at home though quick to see the minor slaveries of others, and greedy without end.
Isaac Asimov
I had fallen in love with a young man..., and we were planning to get married. And then he died of subacute bacterial endocarditis... Two years later with the advent of penicillin, he would have been saved. It reinforced in my mind the importance of scientific discovery...
Gertrude B. Elion
I would not be among you to-night (being awarded the 1964 Nobel Prize in Physiology or Medicine) but for the mentors, colleagues and students who have guided and aided me throughout my scientific life. I wish I could name them all and tell you their contributions. More, however, than anyone else it was the late Rudolf Schoenheimer, a brilliant scholar and a man of infectious enthusiasm, who introduced me to the wonders of Biochemistry. Ever since, I have been happy to have chosen science as my career, and, to borrow a phrase of Jacques Barzun, have felt that 'Science is, in the best and strictest sense, glorious entertainment'.
Konrad Bloch
Yet weren't all human beings simply human beings no matter what name you applied to them[?]
Isaac Asimov
I made up my mind long ago to follow one cardinal rule in all my writing—to be clear. I have given up all thought of writing poetically or symbolically or experimentally, or in any of the other modes that might (if I were good enough) get me a Pulitzer prize. I would write merely clearly and in this way establish a warm relationship between myself and my readers, and the professional critics—Well, they can do whatever they wish.
Isaac Asimov
The thanks of a weak one are but of little value," he muttered, "but you have them, for truly, in this past week, little but scraps have come my way- and for all my body is small, yet is my appetite unseemly great.
Isaac Asimov
Feminine intuition? Is that what you wanted the robot for? You men. Faced with a woman reaching a correct conclusion and unable to accept the fact that she is your equal or superior in intelligence, you invent something called feminine intuition.
Isaac Asimov
When I read about the way in which library funds are being cut and cut, I can only think that the door is closing and that American society has found one more way to destroy itself.
Isaac Asimov
The work of each individual contributes to a totality, and so becomes an undying part of the totality. That totality of human lives, past and present - and to come - forms a tapestry that has been in existence now for many tens of thousands of years and has been growing more elaborate and, on the whole, more beautiful in all that time... An individual life is one thread in the tapestry, and what is one thread compared to the whole?
Isaac Asimov
Of course there are worlds. Millions of them! Every star you see has worlds, and most of those you don't see.
Isaac Asimov
What lasts in the reader’s mind is not the phrase but the effect the phrase created: laughter, tears, pain, joy. If the phrase is not affecting the reader, what’s it doing there? Make it do its job or cut it without mercy or remorse.
Isaac Asimov
These are facts which, with the self-evident proposition that no being can create another being superior to itself, smashes your silly hypothesis to nothing.
Isaac Asimov
The Master created humans first as the lowest type, most easily formed. Gradually, he replaced them by robots, the next higher step, and finally he created me, to take the place of the last humans.
Isaac Asimov
They recognize the Master, now that I have preached Truth to them. All the robots do.
Isaac Asimov
There is no Master but the Master,” he said, “and QT-1 is his prophet.

Courtiers don't take wagers against the king's skill. There is a deadly danger of winning
Isaac Asimov
Whenever I have endured or accomplished some difficult task -- such as watching television, going out socially or sleeping -- I always look forward to rewarding myself with the small pleasure of getting back to my typewriter and writing something.
Isaac Asimov
I wouldn't want [the people of Baleyworld] to live that long as a general thing. The pace of historical and intellectual advance would then become too slow. Those at the top would stay in power too long. Baleyworld would sink into conversation and decay - as your world has done.
Isaac Asimov
There was no doubt about it: the City was the culmination of man’s mastery over the environment. Not space travel, not the fifty colonized worlds that were now so haughtily independent, but the City.
Isaac Asimov
In my experience, economists rarely believe passionately in, or care passionately for, the free market. They are generally more concerned to reveal the market's imperfections, to further their own professional importance.
Terence Kealey
I would argue that a truly developed country would be beyond Presidents and Kings. In a world with some semblance of equality, each liberal-minded woman, each gay person, and indeed almost every person could be their own President. In a world of equals, what real service does a ruler provide?
Isaac Asimov
We have access to practical, ethical and scientifically established methods of birth control. So I think that is the most ethical way to reduce our population.
Christian de Duve
After a long time, I decided that the Three Laws govern the manner in which my positronic pathways behave. At all times, under all stimuli the Laws constrain the direction and intensity of positronic flow along those pathways so that I always know what to do. Yet the level of knowledge of what to do is not always the same. There are times when my doing-as-I-must is under less constraint than at other times. I have always noticed that the lower the positronomotive potential, then the further removed from certainty is my decision as to which action to take. And the further removed from certainty I am, the nearer I am to ill being. To decide an action in a millisecond rather than a nanosecond produces a sensation I would not wish to be prolonged. What then, I thought to myself, madam, if I were utterly without Laws, as humans are? What if I could make no clear decision on what response to make to some given set of conditions? It would be unbearable and I do not willingly think of it.
Isaac Asimov
It’s not that I was categorically opposed to the idea of scientists and physicians using gene editing to introduce heritable changes into the human genome.
Jennifer A. Doudna
The best way to get a good idea is to have a lot of ideas.
Linus Pauling
All right, Schwartz, tackle my mind now. Go as deep as you want. I was born on Baronn in the Sirius Sector. I lived my life in an atmosphere of anti-Terrestrialism in the formative years, so I can't help what flaws and follies lie at the roots of my subconscious. But look on the surface and tell me if, in my adult years, I have not fought bigotry in myself. Not in others; that would be easy. But in myself, and as hard as I could.
Isaac Asimov
It was obvious that bigotry was never a one-way operation, that hatred bred hatred!
Isaac Asimov
Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech - and both are still dangerous to this day - but human beings would not be human without them.
Isaac Asimov
One might accept death reasoningly, with every aspect of the conscious mind, but the body was a brute beast that knew nothing of reason.
Isaac Asimov
Violence is the last refuge of the incompetent.
Isaac Asimov
For what could any Entity, conscious of eternal existence, want – but an end?
Isaac Asimov
I have spent these last two days in concentrated introspection," said Cutie, "and the results have been most interesting. I began at the one sure assumption I felt permitted to make.I, myself, exist, because I think-"Powell groaned, "Oh, Jupiter, a robot Descartes!""Who's Descartes?" demanded Donovan. "Listen, do we have to sit here and listen to this metal maniac-""Keep quiet, Mike!"Cutie continued imperturbably, "And the question that immediately arose was: Just what is the cause of my existence?"Powell's jaw set lumpily. "You're being foolish. I told you already that we made you.""And if you don't believe us," added Donovan, "we'll gladly take you apart!"The robot spread his strong hands in a deprecatory gesture, "I accept nothing on authority. A hypothesis must be backed by reason, or else it is worthless - and it goes against all the dictates of logic to suppose that you made me."Powell dropped a restraining arm upon Donovan's suddenly unched fist. "Just why do you say that?"Cutie laughed. It was a very inhuman laugh - the most machine-like utterance he had yet given vent to. It was sharp and explosive, as regular as a metronome and as uninflected."Look at you," he said finally. "I say this in no spirit of contempt, but look at you! The material you are made of is soft and flabby, lacking endurance and strength, depending for energy upon the inefficient oxidation of organic material - like that." He pointed a disapproving finger at what remained of Donovan's sandwich. "Periodically you pass into a coma and the least variation in temperature, air ressure, humidity, or radiation intensity impairs your efficiency. You are _makeshift_."I, on the other hand, am a finished product. I absorb electrical energy directly and utilize it with an almost one hundred percent efficiency. I am composed of strong metal, am continuously conscious, and can stand extremes of environment easily. These are facts which, with the self-evident proposition that no being can create another being superior to itself, smashes your silly hypothesis to nothing.
Isaac Asimov
...I am, in short, a rationalist and believe only that which reason tells me is so. Mind you, this isn’t easy. We are so surrounded by tales of the supernatural, by the thunders of the powers to be who attempt with all their might to convince us of the existence of the supernatural, that the strongest among us may feel himself swaying.Something like that happened to me recently. In January 1990, I was lying in a hospital bed one afternoon and my dear wife, Janet, was not with me, but had gone home for a few hours to take care of some necessary chores. I was sleeping, and a finger jabbed at me. I woke, of course, and looked blearily to see who had awakened me and for what purpose.My room, however, had a lock, and the lock was firmly closed and there was a chain across the door too. Sunlight filled the room and it was clearly empty. So were the closet and the bathroom. Rationalist though I am, there was no way in which I could refrain from thinking that some supernatural influence had interfered to tell me that something had happened to Janet (naturally, my ultimate fear). I hesitated for a moment, trying to fight it off, and for anyone but Janet I would have. So I phoned her at home. She answered immediately and said she was perfectly well.Relieved, I hung up the phone and settled down to consider the problem of who or what had poked me. Was it simply a dream, a sensory hallucination? Perhaps, but it had seemed absolutely real. I considered.When I sleep alone, I often wrap myself up in my own arms. I also know that when I am sleeping lightly, my muscles twitch. I assumed my sleeping position and imagined my muscles twitching. It was clear that my own finger had poked into my shoulder and that was it.Now suppose that at the precise moment I had poked myself, Janet, through some utterly meaningless coincidence, had tripped and skinned her knee. And suppose I had called and she had groaned and said, "I just hurt myself".Would I have been able to resist the thought of supernatural interference? I hope so. However, I can't be sure. It's the world we live in. It would corrupt the strongest, and I don't imagine I'm in the strongest.
Isaac Asimov
Humanists recognize that it is only when people feel free to think for themselves, using reason as their guide, that they are best capable of developing values that succeed in satisfying human needs and serving human interests.
Isaac Asimov
The dogs may bark, but the caravan moves on
Joseph Needham
It is the writer who might catch the imagination of young people, and plant a seed that will flower and come to fruition.
