It is possible to express the laws of thermodynamics in the form of independent principles , deduced by induction from the facts of observation and experiment, without reference to any hypothesis as to the occult molecular operations with which the sensible phenomena may be conceived to be connected; and that course will be followed in the body of the present treatise. But, in giving a brief historical sketch of the progress of thermodynamics, the progress of the hypothesis of thermic molecular motions cannot be wholly separated from that of the purely inductive theory.

Most students of nature sooner or later pass through a process of writing off a large percentage of their supposed capital of knowledge as a merely illusory asset. As we trace more accurately certain familiar sequences of phenomena we begin to realize how closely these sequences, or laws , as we call them, are hemmed round by still other laws of which we can form no notion. With myself this writing off of illusory assets has gone rather far and the cobweb of supposed knowledge has been pinched (as some one has phrased) into a particularly small pill.william crookes
But mainly I learned, in approaching the measurement of new phenomena, not just to consider using existing apparatus but to allow the mind to wander freely and invent new ways of doing the job .val logsdon fitch
Unlike the position that exists in the physical sciences , in economics and other disciplines that deal with essentially complex phenomena, the aspects of the events to be accounted for about which we can get quantitative data are necessarily limited and may not include the important ones.friedrich hayek
As discontinuity marched into the world of phenomena through one door, causality walked out through another.james jeans
In thermodynamics as well as in other branches of molecular physics , the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity.william john macquorn rankine
The laws of thermodynamics may be regarded as particular cases of more general laws, applicable to all such states of matter as constitute Energy , or the capacity to perform work, which more general laws form the basis of the science of energetics, a science comprehending, as special branches, the theories of motion, heat, light , electricity , and all other physical phenomena.william john macquorn rankine
This kid may be the key not just to all human potential, but to all spiritual unexplained paranormal phenomena. The key to everything in The X-Files.
It can scarcely be denied that the fundamental phenomena which first led mankind into chemical inquiries are those of combustion.
At any one time there is a natural tendency among physicists to believe that we already know the essential ingredients of a comprehensive theory . But each time a new frontier of observation is broached we inevitably discover new phenomena which force us to modify substantially our previous conceptions. I believe this process to be unending, that the delights and challenges of unexpected discovery will continue always.val logsdon fitch
The number of different optical phenomena has become in our time so great that caution must be taken so as to avoid being deceived, and also to refer the phenomena to the simple laws.joseph von fraunhofer
I can have little patience with those who oppose … the theory of evolution or what are called "mechanistic" explanations of the phenomena of life because of certain moral consequences which at first seem to follow from these theories, and still less with those who regard it as irrelevant or impious to ask certain questions at all. By refusing to face the facts , the conservative only weakens his own position.friedrich hayek
The complete closed world consists of three parts-substratum, phenomenal world, and observer. By our experiments we drag up activities from the substratum into the phenomenal world of space and time , but there is no clear line of demarcation between subject and object, and by performing observations on the world, we alter it, much as a fisherman dragging up fish from the depths of the seas disturbs the waters and also damages the fish.james jeans
A hypothetical theory is necessary, as a preliminary step, to reduce the expression of the phenomena to simplicity and order before it is possible to make any progress in framing an abstractive theory.william john macquorn rankine
Our alleged facts might be true in all kinds of ways without contradicting any truth already known. I will dwell now on only one possible line of explanation, not that I see any way of elucidating all the new phenomena I regard as genuine, but because it seems probable I may shed a light on some of those phenomena. All the phenomena of the universe are presumably in some way continuous; and certain facts, plucked as it were from the very heart of nature , are likely to be of use in our gradual discovery of facts which lie deeper still.william crookes
