Doctors can do almost anything nowadays, can't they, unless they kill you while they're trying to cure you.

Doctors have been exposed-you always will be exposed-to the attacks of those persons who consider their own undisciplined emotions more important than the world's most bitter agonies-the people who would limit and cripple and hamper research because they fear research may be accompanied by a little pain and suffering.

DNA has been aptly described as the first three-dimensional Xerox machine.

DOCTOR. Always preceded by 'The good'. Among men, in familiar conversation, 'Oh! balls, doctor!' Is a wizard when he enjoys your confidence, a jack-ass when you're no longer on terms. All are materialists: 'you can't probe for faith with a scalpel.'

Doctor Johnson said, that in sickness there were three things that were material; the physician, the disease, and the patient: and if any two of these joined, then they get the victory; for, Ne Hercules quidem contra duos [Not even Hercules himself is a match for two]. If the physician and the patient join, then down goes the disease; for then the patient recovers: if the physician and the disease join, that is a strong disease; and the physician mistaking the cure, then down goes the patient: if the patient and the disease join, then down goes the physician; for he is discredited.

Dogbert gazing at night sky No matter how bad the day is, the stars are always there. Dilbert Actually, many of them burned out years ago, but their light is just now reaching earth. DogbertThank you for shattering my comfortable misconception. DilbertIt's the miracle of science.

Dogbert: So, Since Columbus is dead, you have no evidence that the earth is round. Dilbert: Look. You can Ask Senator John Glenn. He orbited the earth when he was an astronaut. Dogbert: So, your theory depends on the honesty of politicians. Dilbert: Yes... no, wait.

Dogbert: Scientists have discovered the gene that makes some people love golf. Dilbert: How can they tell it's the golf gene? Dogbert: It's plaid and it lies.

Do not discuss the religious matters with people; do not waste your valuable time to discuss the untruth! Your time is short; spend it for the science and the art!

Do not Bodies and Light act mutually upon one another; that is to say, Bodies upon Light in emitting, reflecting, refracting and inflecting it, and Light upon Bodies for heating them, and putting their parts into a vibrating motion wherein heat consists?

Do not say hypothesis, and even less theory: say way of thinking.

Do not quench your inspiration and your imagination; do not become the slave of your model.

Do not great Bodies conserve their heat the longest, their parts heating one another, and may not great dense and fix'd Bodies, when heated beyond a certain degree, emit Light so copiously, as by the Emission and Re-action of its Light, and the Reflexions and Refractions of its Rays within its Pores to grow still hotter, till it comes to a certain period of heat, such as is that of the Sun?

Do not try the parallels in that way: I know that way all along. I have measured that bottomless night, and all the light and all the joy of my life went out there.

Do not the Rays which differ in Refrangibility differ also in Flexibity; and are they not by their different Inflexions separated from one another, so as after separation to make the Colours in the three Fringes above described? And after what manner are they inflected to make those Fringes?

Do not trust your memory; it is a net full of holes; the most beautiful prizes slip through it.

Do not expect to be hailed as a hero when you make your great discovery. More likely you will be a ratbag-maybe failed by your examiners. Your statistics, or your observations, or your literature study, or your something else will be patently deficient. Do not doubt that in our enlightened age the really important advances are and will be rejected more often than acclaimed. Nor should we doubt that in our own professional lifetime we too will repudiate with like pontifical finality the most significant insight ever to reach our desk.

Don't let me catch anyone talking about the Universe in my department.

Do you believe then that the sciences would ever have arisen and become great if there had not before hand been magicians, alchemists, astrologers and wizards, who thirsted and hungered after abscondite and forbidden powers?

Do you see this egg? With this you can topple every theological theory, every church or temple in the world.

Doubt is the beginning, not the end, of wisdom.

Doubtless many can recall certain books which have greatly influenced their lives, and in my own case one stands out especially-a translation of Hofmeister's epoch-making treatise on the comparative morphology of plants. This book, studied while an undergraduate at the University of Michigan, was undoubtedly the most important factor in determining the trend of my botanical investigation for many years.

Drive Nature out with a pitchfork, yet she hurries back, And will burst through your foolish contempt, triumphant.

Dr. Johnson ... sometimes employed himself in chymistry, sometimes in watering and pruning a vine, and sometimes in small experiments, at which those who may smile, should recollect that there are moments which admit of being soothed only by trifles.

Drive out Nature with a fork, she comes running back.

During cycles long anterior to the creation of the human race, and while the surface of the globe was passing from one condition to another, whole races of animals-each group adapted to the physical conditions in which they lived-were successively created and exterminated.

During my span of life science has become a matter of public concern and the l'art pour l'art standpoint of my youth is now obsolete. Science has become an integral and most important part of our civilization, and scientific work means contributing to its development. Science in our technical age has social, economic, and political functions, and however remote one's own work is from technical application it is a link in the chain of actions and decisions which determine the fate of the human race. I realized this aspect of science in its full impact only after Hiroshima.

During an intense period of lab work, the outside world vanishes and the obsession is total. Sleep is when you can curl up on the accelerator floor for an hour.

During human progress, every science is evolved out of its corresponding art.

During its development the animal passes through all stages of the animal kingdom. The foetus is a representation of all animal classes in time.

Do you remember how electrical currents and 'unseen waves' were laughed at? The knowledge about man is still in its infancy.

During my second year at Edinburgh [1826-27] I attended Jameson's lectures on Geology and Zoology, but they were incredible dull. The sole effect they produced on me was the determination never as long as I lived to read a book on Geology.

During the last two centuries and a half, physical knowledge has been gradually made to rest upon a basis which it had not before. It has become mathematical. The question now is, not whether this or that hypothesis is better or worse to the pure thought, but whether it accords with observed phenomena in those consequences which can be shown necessarily to follow from it, if it be true

Each generation of humanity takes the earth as trustees... We ought to bequeath to posterity as many forests and orchards as we have exhausted and consumed.

Each generation has its few great mathematicians, and mathematics would not even notice the absence of the others. They are useful as teachers, and their research harms no one, but it is of no importance at all. A mathematician is great or he is nothing.

Each person is an idiom unto himself, an apparent violation of the syntax of the species.

Early in my school career, I turned out to be an incorrigible disciplinary problem. I could understand what the teacher was saying as fast as she could say it, I found time hanging heavy, so I would occasionally talk to my neighbor. That was my great crime, I talked in school.

Each metal has a certain power, which is different from metal to metal, of setting the electric fluid in motion.

Each time one of the medicine men dies, it's as if a library has burned down.

Earlier this week ... scientists announced the completion of a task that once seemed unimaginable; and that is, the deciphering of the entire DNA sequence of the human genetic code. This amazing accomplishment is likely to affect the 21st century as profoundly as the invention of the computer or the splitting of the atom affected the 20th century. I believe that the 21st century will be the century of life sciences, and nothing makes that point more clearly than this momentous discovery. It will revolutionize medicine as we know it today.

Earth's sweat, the sea.

Ecologically speaking, a spilt tanker load is like sticking a safety pin into an elephant's foot. The planet barely notices. After the Exxon Valdez accident in Alaska the oil company spent billions tidying up the coastline, but it was a waste of money because the waves were cleaning up faster than Exxon could. Environmentalists can never accept the planet's ability to self-heal.

Earth has few secrets from the birds.

Earthquakes traveling through the interior of the globe are like so many messengers sent out to explore a new land. The messages are constantly coming and seismologists are fast learning to read them.

EAT, v.i. To perform successively (and successfully) the functions of mastication, humectation, and deglutition.

During the time that [Karl] Landsteiner gave me an education in the field of imununology, I discovered that he and I were thinking about the serologic problem in very different ways. He would ask, What do these experiments force us to believe about the nature of the world? I would ask, What is the most. simple and general picture of the world that we can formulate that is not ruled by these experiments? I realized that medical and biological investigators were not attacking their problems the same way that theoretical physicists do, the way I had been in the habit of doing.

Edible, adj.: Good to eat, and wholesome to digest, as a worm to a toad, a toad to a snake, a snake to a pig, a pig to a man, and a man to a worm.

During the war years I worked on the development of radar and other radio systems for the R.A.F. and, though gaining much in engineering experience and in understanding people, rapidly forgot most of the physics I had learned.

Edison was by far the most successful and, probably, the last exponent of the purely empirical method of investigation. Everything he achieved was the result of persistent trials and experiments often performed at random but always attesting extraordinary vigor and resource. Starting from a few known elements, he would make their combinations and permutations, tabulate them and run through the whole list, completing test after test with incredible rapidity until he obtained a clue. His mind was dominated by one idea, to leave no stone unturned, to exhaust every possibility.

Education has now become the chief problem of the world, its one holy cause. The nations that see this will survive, and those that fail to do so will slowly perish. . . . There must be re-education of the will and of the heart as well as of the intellect; and the ideals of service must supplant those of selfishness and greed.
