Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.
Reality is a cruel and unintuitive place with frustrating gameplay mechanics. (Press X to thanklessly toil your life away)
Let's say you're a garage mechanic, and you have big dreams about opening up your own chain of branded garages around the country. Terrific.
And in that narrow cockpit I wept, as I shall never weep again, when I felt the concrete brush against his wheels and, with a great sweep of the wrist, dropped him on the ground like a cut flower. As always, I carefully cleared the engine, turned off all the switches one by one, removed the straps, the wires and the tubes which tied me to him, like a child to his mother. And when my waiting pilots and my mechanics saw my downcast eyes and my shaking shoulders, they understood and returned to the dispersal in silence.
Husband, when you tell your wife to go for counseling alone (because you think going to see a counselor is a sign you have failed) is like having a car you love overheat and deciding it's not manly to take it to the mechanic. You can keep on driving it but eventually you will ruin the engine.
Affluence includes money but is not just money. It is the abundance, the flow, the generosity of the universe, where every desire we have must come true, because inherent in having the desire are the mechanics for its fulfillment.
I don't want to be a great leader; I want to be a man who goes around with a little oil can and when he sees a breakdown, offers his help. To me, the man who does that is greater than any holy man in saffron-colored robes. The mechanic with the oil can: that is my ideal in life.
My greatest concern was what to call it. I thought of calling it 'information,' but the word was overly used, so I decided to call it 'uncertainty.' When I discussed it with John von Neumann, he had a better idea. Von Neumann told me, 'You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage.'
History is nothing but a problem of mechanics applied to psychology.
Our greatest leaders are neither dreamers nor dictators: They are, like Jefferson, those who articulate national aspirations yet master the mechanics of influence and know when to depart from dogma.
From the point of view of logic, my report on 'Exclusion principle and quantum mechanics' has no conclusion. I believe that it will only be possible to write the conclusion if a theory will be established which will determine the value of the fine structure constant and will thus explain the atomistic structure of electricity, which is such an essential quality of all atomic sources of electric fields actually occurring in nature.
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
A poet is a time mechanic not an embalmer.
Its nice to have a catcher who knows my mechanics, too. That way if I get into trouble he can stop it before I get out of control.
Anyone not shocked by quantum mechanics has not yet understood it.
It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.
Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.
Modern physics has changed nothing in the great classical disciplines of, for instance, mechanics, optics, and heat. Only the conception of hitherto unexplored regions, formed prematurely from a knowledge of only certain parts of the world, has undergone a decisive transformation. This conception, however, is always decisive for the future course of research.
As is well known the principle of virtual velocities transforms all statics into a mathematical assignment, and by D'Alembert's principle for dynamics, the latter is again reduced to statics. Although it is is very much in order that in gradual training of science and in the instruction of the individual the easier precedes the more difficult, the simple precedes the more complicated, the special precedes the general, yet the min, once it has arrived at the higher standpoint, demands the reverse process whereby all statics appears only as a very special case of mechanics.
Schrödinger's wave-mechanics is not a physical theory, but a dodge - and a very good dodge too.
After a duration of a thousand years, the power of astrology broke down when, with Copernicus, Kepler, and Galileo, the progress of astronomy overthrew the false hypothesis upon which its entire structure rested, namely, the geocentric system of the universe. ... the earth revolves in space intervened to upset the complicated play of planetary influences, and the silent stars, relegated to the unfathomable depths of the sky, no longer made their prophetic voices audible to mankind.
As the component parts of all new machines may be said to be old[,] it is a nice discriminating judgment, which discovers that a particular arrangement will produce a new and desired effect. ... Therefore, the mechanic should sit down among levers, screws, wedges, wheels, etc. like a poet among the letters of the alphabet, considering them as the exhibition of his thoughts; in which a new arrangement transmits a new idea to the world.
The valuable properties of this cement depend in a great measure on the mode of preparing it for use. The mixing should therefore be conducted with care in order to form a perfect union of the powdered cement, sand and water. This can be best accomplished by the use of the New England corn hoe on a board floor or by beating with a hand stamper; not much labour is required if properly applied. Mechanics can judge when the mixture is perfect by the appearance of the mortar, which, when properly prepared, very much resembles putty.
Cell genetics led us to investigate cell mechanics. Cell mechanics now compels us to infer the structures underlying it. In seeking the mechanism of heredity and variation we are thus discovering the molecular basis of growth and reproduction. The theory of the cell revealed the unity of living processes; the study of the cell is beginning to reveal their physical foundations.
In fact, Gentlemen, no geometry without arithmetic, no mechanics without geometry... you cannot count upon success, if your mind is not sufficiently exercised on the forms and demonstrations of geometry, on the theories and calculations of arithmetic ... In a word, the theory of proportions is for industrial teaching, what algebra is for the most elevated mathematical teaching.
