Mechanical Quotes - page 12
My memoirs "On the Mechanical Theory of Heat" are of different kinds. Some are devoted to the development of the general theory and to the application thereof to those properties of bodies which are usually treated of in the doctrine of heat. Others have reference to the application of the mechanical theory of heat to electricity. ...Other memoirs... have reference to the conceptions I have formed of the molecular motions which we call heat. These conceptions, however, have no necessary connexion with the general theory, the latter being based solely on certain principles which may be accepted without adopting any particular view as to the nature of molecular motions. I have therefore kept the consideration of molecular motions quite distinct from the exposition of the general theory.
Rudolf Clausius
An explanation of a phenomenon is regarded, apparently instinctively, as the most general possible when it is a mechanical explanation. The "mechanism" of the process is the ultimate goal of experiment. Now this mechanism in general lies beyond the range of the senses; either by reason of their limitations, as in the case of the atomic structure of matter, or by the very nature of the supposed mechanism, as in the theory of the ether. The only way to bridge the gap between the machinery of the physical process and the world of sense-impressions is to think out some consequence of that mechanism. This we will call the hypothesis. The hypothesis, resting still on the mechanical basis, is yet beyond the range of direct experimental investigation; but if, by mathematical reasoning, a consequence of the hypothesis can be deduced, this will often lie within the range of experimental inquiry, and thus a test of the soundness of the original mechanical conception may be instituted.
J. R. Partington
It looks as if the war in Europe is rapidly moving towards a conclusion. Probably I am wrong about that but I can't see how it can be otherwise. It seems clear that the Allies are outclassed on mechanical equipment, and it is foolish to talk about modernizing their Armies in times like these, they ought to have thought of that five years ago. There is no excuse for them not thinking of that except for the unintelligent, in fact, stupid, narrow-minded and selfish leadership which the democracies of the world are cursed with.
It is all very well as everybody is in the same position, but when some other system develops stronger leadership, works hard and long, and intelligently and aggressively-which are good traits-and, superimposed upon that, develops the instinct of a racketeer, there is nothing for the democracies to do but fold up. And that is about what it looks as if they are going to do.
Alfred P. Sloan
There was excitement for us all in the fact that I had a job in the mechanical field, so that my education would count.... Well, I am bound to admit the first sight of my opportunity was disappointing... Not far from a city dump on a weed-grown, marshy plain was an old weather-worn building, like an overgrown barn. In its indefinite yard there was a small mound of coal and a great mound of reddish-gray cinders and ashes; also a disorderly accumulation of discarded machinery... Once the factory had been painted brown. Only one word describes it: "dirty." Smoke from the dump carried an acric odor. Eventually across the wall nearest the railroad track there was lettered in black this legend: HYATT ROLLER BEARING COMPANY.
Alfred P. Sloan
Roll a ball under your hand on a table and roll a pencil in the same manner. What you feel are "point" and "line" bearings. But to understand what mechanics mean by a surface "bearing," grasp a pencil in your hand and use your other hand to make it turn as a piece of shafting. Now, the lower half of the shaft is supported everywhere by contact with your hand - the upper half is not supported, merely covered. The advantages of ball and roller bearings were obvious many years ago to mechanical people... Solid steel rollers, being inflexible, were not satisfactory at that stage, but a Hyatt flexible roller bearing was different. We had something. Our spirally wound tube roller had a springlike quality, yielded to irregularities caused by poor manufacture, thus making automatic adjustments between housing and bearing.
Alfred P. Sloan
Archytas of Tarentum found the two mean proportionals by a very striking construction in three dimensions, which shows that solid geometry, in the hands of Archytas at least, was already well advanced. The construction was usually called mechanical, which it no doubt was in form, though in reality it was in the highest degree theoretical. It consisted in determining a point in space as the intersection of three surfaces: (a) a cylinder, (b) a cone, (c) an "anchor-ring" with internal radius = 0.
Thomas Little Heath
A mechanical manufacture being commonly occupied with one substance, which it conducts through metamorphoses in regular succession^ may be made nearly automatic; whereas a chemical manufacture depends on the play of delicate affinities between two or more substances, which it has to subject to heat and mixture under circumstances somewhat uncertain, and must therefore remain, to a corresponding extent, a manual operation.
Andrew Ure
I think there's a quality of passion to the American actor. I'm certainly attracted to it, and I like to hope that underscoring it is a characteristic of my work. That quality is certainly also present in some British actors, but I tend to feel the mechanical and intellectual process is dominant in the British.
Arthur Penn
I believe that we in the medical profession have taken the wrong course. It is as if we were simply standing by, watching millions of people march over a cliff, and then intervening in a desperate, last-minute attempt to save them once they have fallen over the edge. Instead, we should be teaching them how to avoid the chasm entirely, how to walk parallel to the precipice so that they will never fall at all. I believe that coronary artery disease is preventable, and that even after it is under way, its progress can be stopped, its insidious effects reversed. I believe, and my work over the past twenty years has demonstrated, that all this can be accomplished without expensive mechanical intervention and with minimal use of drugs. The key lies in nutrition-specifically, in abandoning the toxic American diet and maintaining cholesterol levels well below those historically recommended by health policy experts.
Caldwell Esselstyn
Often, equipment can as easily function as a security blanket for musicians unwilling or unable to risk anything personal in the studio. Whether one catches the feeling on a record is a subjective matter. How can you be sure? The machinery can hold out the promise of at least mechanical perfection.
