Phenomenon Quotes - page 50
A law explains a set of observations; a theory explains a set of laws. The quintessential illustration of this jump in level is the way in which Newton's theory of mechanics explained Kepler's law of planetary motion. Basically, a law applies to observed phenomena in one domain (e.g., planetary bodies and their movements), while a theory is intended to unify phenomena in many domains. Thus, Newton's theory of mechanics explained not only Kepler's laws, but also Galileo's findings about the motion of balls rolling down an inclined plane, as well as the pattern of oceanic tides. Unlike laws, theories often postulate unobservable objects as part of their explanatory mechanism. So, for instance, Freud's theory of mind relies upon the unobservable ego, superego, and id, and in modern physics we have theories of elementary particles that postulate various types of quarks, all of which have yet to be observed.
Johannes Kepler
I esteem myself happy to have as great an ally as you in my search for truth. I will read your work ... all the more willingly because I have for many years been a partisan of the Copernican view because it reveals to me the causes of many natural phenomena that are entirely incomprehensible in the light of the generally accepted hypothesis. To refute the latter I have collected many proofs, but I do not publish them, because I am deterred by the fate of our teacher Copernicus who, although he had won immortal fame with a few, was ridiculed and condemned by countless people (for very great is the number of the stupid).
Johannes Kepler
The great invention... Descartes gave to the world, the analytical diagram, ...gives at a glance a graphical picture of the law governing a phenomenon, or of the correlation which exists between dependent events, or of the changes which a situation undergoes in the course of time. ...the invention of Descartes not only created the important discipline of analytic geometry, but it gave Newton, Leibnitz, Euler, and the Bernoullis that weapon for the lack of which Archimedes and later Fermat had to leave inarticulate their profound and far-reaching thoughts.
René Descartes
There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. It demands the same skill, devotion, insight, and even inspiration as the discovery of the simple physical laws which underlie the complex phenomena of nature.
C. A. R. Hoare
The great thing however is, in the show of the temporal and the transient to recognize the substance which is immanent and the eternal which is present. For the work of Reason (which is synonymous with the Idea) when considered in its own actuality, is to simultaneously enter external existence and emerge with an infinite wealth of forms, phenomena and phases - a multiplicity that envelops its essential rational kernel with a motley outer rind with which our ordinary consciousness is earliest at home. It is this rind that the Concept must penetrate before Reason can find its own inward pulse and feel it still beating even in the outward phases. But this infinite variety of circumstances which is formed in this element of externality by the light of the rational essence shining in it - all this infinite material, with its regulatory laws - is not the object of philosophy....To comprehend what is, is the task of philosophy: and what is is Reason.
Georg Wilhelm Friedrich Hegel
Our experience hitherto justifies us in trusting that nature is the realization of the simplest that is mathematically conceivable. I am convinced that purely mathematical construction enables us to find those concepts and those lawlike connections between them that provide the key to the understanding of natural phenomena. Useful mathematical concepts may well be suggested by experience, but in no way can they be derived from it. Experience naturally remains the sole criterion of the usefulness of a mathematical construction for physics. But the actual creative principle lies in mathematics. Thus, in a certain sense, I take it to be true that pure thought can grasp the real, as the ancients had dreamed.
Albert Einstein
I have been told that Dalrymple is a personable man, and in my own encounters with him I have indeed found him so, but what is of interest in this context is not Dalrymple the man, but Dalrymple the phenomenon. How did a White man, young, irreverent and likeable in his first and by far most readable India book, The City of Djinns, become the pompous arbiter of literary merit in India?
William Dalrymple (historian)
The science of neuroendocrinology-the brain-to-pituitary link that was discerned by [Joe] Hinsey, [George] Wislocki, du Vigneaud, and [Geoffrey] Harris-is dependent upon hormones flowing within nerve axons. This phenomenon, axonal flow, was first noted by Ernst and Barta Scharrer... For many decades it was assumed that axonal flow was always 'down'... away from the brain.
Richard Bergland
Along with this came another New Deal phenomenon, a kind of pervasive tenderness for the underdog, for the Okies, the sharecroppers, the characters of John Steinbeck's novels, the subjects who posed for the FSA photographers, for what were called, until a revulsion set in, "the little people.”.
Richard Hofstadter
