Scientists

“ We must appeal to the scientists, who, following the example of Lavoisier, Berzelius, Regnault, and Liebig, have applied to the study of living beings the resources of general science, and have thus founded chemical biology. ”

“ But it can grasp the general character of scientific procedure, appreciate its difficulties and dangers, understand the expedients for meeting them, and trace it to its roots in the constitution of the human mind and in the needs of life (§ 35) .
(5) In virtue of its general grasp of the aim and method of the sciences a logic of science can at times offer advice to scientists: it may draw their attention to the general problems which their work involves, but which are apt to be overlooked by specialists, such as the claims of consistency and novelty and the regulation of risks (§ 36) . ”

“ He did much to increase public interest in and knowledge of the development of the science by frequent popular articles in the leading magazines, in addition to more technical books and memoirs intended especially for scientists.
Of living scientists, we can do no more than mention a few. ”

“ I've heard some folks try to dodge the evidence by saying they're not scientists; that we don't have enough information to act. Well, I'm not a scientist, either. But you know what -- I know a lot of really good scientists at NASA, and NOAA, and at our major universities. ”

“ Great inventions and discoveries appear to be made in response to national needs and are preceded by long periods during which the preparatory work is being done. The great men of science being active generalizes, need the cooperation of many lesser scientists to collect data and observations upon which general theories may be built. ”

“ Scientists animated by the purpose of proving that they are purposeless constitute an interesting subject for study. ”

“ The advance of scientific knowledge—the astonishing discovery of the atom and the cell, and of the unsubstantially or unmateriality, so to speak, of matter itself, and of the elusiveness of energy and life, as indicated by the newer theories of the nature of the ether, and the acceptance of thought-transference as a physical or psychological fact—these and other remarkable scientific discoveries which are leading science to what is seemingly the borderline of a world beyond the cognizance of the bodily senses, have powerfully affected the rationalism and idealism of the present day. ”

“ Anyone conversant with a single branch of Natural Science is aware that experiment, as well as observation, is necessary. Who would expect discoveries in physics, or in chemistry, without laboratories and experiments? Do not botanists investigate the functions of plants by dissection, by microscopic and chemical investigation, and by experiment? ”

“ It may be a task, not hopeless, to extract from the past progress of science the elements of an effectual and substantial method of Scientific Discovery. The advances which have, during the last three centuries, been made in the physical sciences;—in Astronomy, in Physics, in Chemistry, in Natural History, in Physiology;—these are allowed by all to be real, to be great, to be striking ”

“ The science has entered upon the stage where work and theory must be continually brought into agreement with chemical, physical and mathematical laws and data, and in the application of these new problems present themselves. As we climb, in fact, new horizons open to our view indicating fresh regions for exploration, for acquiring human knowledge and for our satisfaction. ”

“ I have been compelled to use the words ‘science’ and ‘scientific’ because these terms have become firmly adherent to a group of subjects such as Physics, Chemistry, Geology, Botany, etc., and cannot now be detached from them. Unfortunately ‘scientific’ is used in another sense as implying accuracy of experimental method and in deduction from results. So that in calling ourselves scientific men we run the risk of seeming to claim a monopoly of method, as though we pretended to be somehow superior to the trained workers in other branches. ”

“ Yes, science to-day, at the close of this nineteenth century, in the laboratory is discovering and scientifically demonstrating the great, immutable laws upon which the inspired and illuminated ones of all ages have based all their teachings, those who by ordering their lives according to the higher laws of their being get in a moment of time, through the direct touch of inspiration, what it takes the physical investigator a whole lifetime or a series of investigators a series of lifetimes to discover and demonstrate. ”

“ The astronomer, the electrician, the chemist, the mineralogist, the botanist, are constantly called upon to perform manual operations of exceeding delicacy. The progress of all branches of physical science depends upon observation, or on that artificial observation68 which is termed experiment, of one kind or another; and, the farther we advance, the more practical difficulties surround the investigation of the conditions of the problems offered to us; so that mobile and yet steady hands, guided by clear vision, are more and more in request in the workshops of science. ”

“ The Study of the Biological and Physical Sciences.—The last century is marked by scientific development along several {466} rather distinct lines as follows: the study of the earth, or geology; animal and vegetable life, or biology; atomic analysis, or chemistry; biochemistry; physics, especially that part relating to electricity and radioactivity; and more recently it might be stated that investigations are carried on in psychology and sociology, while mathematics and astronomy have made progress. ”

“ The most striking, and also the most radical and pervasive, characteristic of our time is, of course, the progress made in scientific knowledge. Month by month enormous numbers of facts are, in every department, added to the knowledge already acquired. To let one’s imagination range, even in a cursory way, over the work that is being done in 38 chemistry and physics merely as they concern biology—to enumerate the subdivisions of these sciences, or to look down a list of recent publications relating to research carried on in them, is enough to make one’s brain reel. ”

“ Science has been built up on the basis of the inquiry into nature's processes. It is all the time inquiring: "What do we find under the microscope, through the telescope, in the chemical and physical reactions, in the examination of the earth and its products, in the observation of the functions of animals and plants, or in the structure of the brain of man and the laws of his mental functioning?" If it establishes an hypothesis as a means of procedure, it must be determined true or abandoned. ”

“ It is a general truth that the physical sciences of light and heat are based upon mechanical conditions of the particles of matter; that the science of chemistry is founded upon physics; that biological phenomena are dependent upon physical and chemical conditions; that psychological subjects are based upon biology; and that biological science cannot progress excepting in proportion to the advance of the sciences on which it is based. ”

“ I am not a practical chemist seeking the mysteries of nature in the laboratory, nor a professional scientist exploring the fields of original research; but, like La Place, Comte, Herbert Spencer and others, I formulate my theories and scientific hypotheses from the latest and best established facts of science as I see it. ”

“ And when, passing from these material fruits, you consider the purely intellectual triumphs of physical science, such as those which have been gained with the telescope, the microscope, and the spectroscope, you can not wonder at the esteem in which these branches of study are held in this practical age of the world. ”

“ In this age of a hundred sciences, all tramping on Nature’s outside with their flags up, and marching her round and round, and searching her through and through for her secrets, and flinging into the public forum their heaps of results, how is it possible to call mind the same as it was a generation or two ago, when the sciences were fewer, their industry more leisurely, and their discoveries less frequent? ”

“ Each science has its own classification of the objects with which it deals, the kinds- of likeness and unlikeness according to which these objects are grouped varying in relation to the special qualities or properties of matter with which the science is concerned. Thus, the physicist classifies bodies according to their mechanical, electrical, thermic, or other physical properties ; the chemist, regards their composition ; while the zoologist and the botanist group them according to their likenesses and unlikenesses of structure, function, and distribution. ”

“ I think that a student during his college course should have [p58] a year’s work in a chemical laboratory or else, if his taste inclines him to botany, geology, or zoölogy, a year’s training of his observing powers in some one of these studies. For he ought to get, while at an impressible age, a superficial knowledge of the methods of scientific men, as a basis for his future reading. We all know that science is moving the world and to keep abreast with the movement is a necessity for every educated man. Happily, there are scientific men who popularize their knowledge. ”

“ We may take some lessons from the scientist. He has enriched knowledge especially in recent years by attacking the no-man's lands left unexplored by the too sharp delimitation of spheres of activity. These new conquests have been especially achieved by the combination of old sciences. Physical chemistry, electro-chemistry, geo-physics, astro-physics, and a variety of other scientic unions have led to audacious hypotheses, veritable flashes of vision, which open new regions of activity for a generation of investigators. ”

“ The definitions which those works furnish of the sciences, for the most part either do not fit them—some being too wide, some too narrow—or do not go deep enough into them, but define a science by its accidents, not its essentials; by some one of its properties which may, indeed, serve the purpose of a distinguishing mark, but which is of too little importance to have ever of itself led mankind to give the science a name and rank as a separate object of study. ”

“ The popular idea of scientific investigation is a vehement, aimless collection of little facts, collected as a bower bird collects shells and pebbles, in methodical little rows, and out of this process, in some manner unknown to the popular mind, certain conjuring tricks—the celebrated “wonders of science”—in a sort of accidental way emerge. ”

“ It was thought that the temper of the really scientific man, so patient in research, so accurate and conscientious, so slow to dogmatize, so deferential to others, might be fostered by experimental science in the schools, acquiring "knowledge at first hand," making experiments, looking with great respect at balances, weighing and measuring, and giving an account of results. ”

“ The science-fiction writer is, therefore, faced with a simply stated problem: Taking off from the solid ground of known laboratory science, sighting along the back-track of past experience, he launches into the future. ”

“ A scientific classification, on the other hand, aims at the utmost comprehensiveness, ransacking the whole world from the depths of the earth to the remotest star for new objects, and scrutinising everything with the aid of crucible and dissecting knife, microscope and spectroscope, to find the qualities and constitution of everything, in order that it may be classed among those things with which it has most in common and distinguished from those other things from which it differs. ”

“ A small number among you may, perhaps, be so circumstanced as to be able to devote yourselves entirely to original scientific research, selecting such branches of inquiry as may have specially interested you here, and giving up your whole time and energy to investigation. A much larger number will, no doubt, enter professions where a scientific training can be turned to practical account, and you may become engineers, chemists, or medical men. ”

“ Indeed, if at the present moment we run over the names distinguished in the several sciences into which Natural Knowledge may be divided—in Physics, in Chemistry, in Botany, in Zoology—we find but few investigators who can be said to have thoroughly mastered the whole range of any one of them. ”

“ After he completes his formal education, the scientist sets about to investigate the world, for that’s what science is all about. The methods he uses to carry out his investigations depend on his particular field. It is impossible to outline what an individual scientist does because he may do any of a thousand things in any of a thousand ways. ”

“ The data of science become unsystematic, scattered, full of gaps and breaks, more like an archipelago than a continent. A thousand investigators, working independently and with but casual reference to each other, may discover a vast number of important facts, advance many useful arts, and yet accomplish but little for definite, exact, systematic, coherent science. ”

“ Natural science has become so vastly extended, its recorded facts and its unanswered questions so immensely multiplied, that every strictly scientific man must be a specialist, and confine the researches of a whole life within a comparatively narrow circle. ”

“ This characteristic of scientific knowledge is not always recognised. I mean the profound difference between what we know and what we are told. When science began to flourish at Cambridge in the ’seventies, and the University was asked to supply money for buildings, an eminent person objected and said, “What do they want with their laboratories?—why can’t they believe their teachers, who are in most cases clergymen of the Church of England?” This person had no conception of what the word ‘knowledge’ means as understood in science. ”
