Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
Lawrence M. Krauss
At the heart of quantum mechanics is a rule that sometimes governs politicians or CEOs-as long as no one is watching, anything goes.
Lawrence M. Krauss
It seems clear that the present quantum mechanics is not in its final form.
Paul Dirac
It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted.
Paul Dirac
Quantum mechanics has explained all of chemistry and most of physics.
Paul Dirac
Renormalization is just a stop-gap procedure. There must be some fundamental change in our ideas, probably a change just as fundamental as the passage from Bohr's orbit theory to quantum mechanics. When you get a number turning out to be infinite which ought to be finite, you should admit that there is something wrong with your equations, and not hope that you can get a good theory just by doctoring up that number.
Paul Dirac
I thought scientists were going to find out exactly how everything worked, and then make it work better. I fully expected that by the time I was twenty-one, some scientist, maybe my brother, would have taken a color photograph of God Almighty-and sold it to Popular Mechanics magazine. Scientific truth was going to make us so happy and comfortable. What actually happened when I was twenty-one was that we dropped scientific truth on Hiroshima.
Kurt Vonnegut
There has never been just one best way to teach quantum mechanics. My goal is neither to sow nostalgia for the philosophically engaged style of Oppenheimer and Nordheim, nor to condemn the pragmatic approach of Fermi, Bethe and Feynman. It is rather to highlight the choices that physicists must always make when stepping into the classroom. Choices of topics to discuss and problems to assign reflect deeper decisions about the ideal type of physicist one seeks to train. Should the new generation be philosophically attuned, concerned with minute details of conceptual interpretation? Or should physicists hone their ability to calculate, pushing Heisenberg's and Schrödinger's equations into the service of ever more elaborate problems to solve and phenomena to analyse? Competing ideals have flourished under different pedagogical conditions.
David Kaiser
Strangely enough, many of the philosophical issues surrounding quantum mechanics are today being used to entice potential students into physics. As quantum computing and quantum communication become a commercial reality, tomorrow's students may find themselves routinely grappling with the same philosophical questions that challenged their forebears almost a century ago.
David Kaiser
Feynman uses Dirac's notation to describe the quantum mechanics of stimulated emission... he applies that physics to... dye molecules... In this regard, Feynman could have predicted the existence of the tunable laser.
F. J. Duarte
The most efficient and practical interpretation of quantum mechanics is... no interpretation at all.
F. J. Duarte
Quantum mechanics is the Disney World for adults!
Jan Zaanen
It must be confessed that the new quantum mechanics is far from satisfying the requirements of the layman who seeks to clothe his conceptions in figurative language. Indeed, its originators probably hold that such symbolic representation is inherently impossible. It is earnestly to be hoped that this is not their last word on the subject, and that they may yet be successful in expressing the quantum postulate in picturesque form.
H. Stanley Allen
The lesson to be learned from what I have told of the origin of quantum mechanics is that probable refinements of mathematical methods will not suffice to produce a satisfactory theory, but that somewhere in our doctrine is hidden a concept, unjustified by experience, which we must eliminate to open up the road.
Max Born
Common Logic is the Grammar of the higher Speech, that is, of Thought; it examines merely the relations of ideas to one another, the Mechanics of Thought, the pure Physiology of ideas. Now logical ideas stand related to one another, like words without thoughts. Logic occupies itself with the mere dead Body of the Science of Thinking.
Novalis
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.
Brian Greene
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.
Brian Greene
People used to try to hijack quantum mechanics and its inherent mystery to cast a cloud around determinism, in the hope that free will could survive modern physics. But that never worked very well. Since when does random chance equal free will? The only salvation for volition is a soul and faith and you're not allowed to ask me about that.
Janna Levin
It is a testimony to the power of education that classical mechanics could operate for so long under a mistaken conception. Teaching and research concentrated on integrable systems, each feeding the other, until in the end we had no longer the tools nor the interest for studying nonintegrable systems.
Ivar Ekeland
The principles of the theory are derived, as are those of rational mechanics, from a very small number of primary facts.
Joseph Fourier
Under these circumstances, men lose sight of themselves and escape into the security of work or sociability or other forms of what Vidich and Bensman have called the "externalization of the self.” Vidich and Bensman sketch a troubling picture of such men: "What is left of the personality is the dulled, autonomic ritualization of behavior where ... no disturbing interferences are allowed to enter into thought. ... Personal and social life becomes barren, and the personal mechanics and daily routine of living become the end-all of existence. All types of activity whose operation is based upon an objective, external, automatic rhythm to which an individual can bend himself serve the function of enabling him to lose himself in an objective ceremony.”.
Benjamin Barber
Not one word is said here of acausality, wave mechanics, indeterminacy relations, complementarity, ... etc. Why doesn't he talk about what he knows instead of trespassing on the professional philosopher's preserves? Ne sutor supra crepidam.
Erwin Schrödinger
