“I speak without exaggeration when I say that I have constructed 3,000 different theories in connection with the electric light, each one of them reasonable and apparently likely to be true. Yet only in two cases did my experiments prove the truth of my theory. My chief difficulty was in constructing the carbon filament... Every quarter of the globe was ransacked by my agents, and all sorts of the queerest materials used, until finally the shred of bamboo, now utilized by us, was settled upon.”

“Economists can never be free of from difficulties unless they will distinguish between a theory and the application of a theory.”

“Although it may be difficult in theory to know what is just and equal, the practical difficulty of inducing those to forbear who can, if they like, encroach, is far greater, for the weaker are always asking for equality and justice, but the stronger care for none of these things.”

“The difficulty involved in the proper and adequate means of describing changes in continuous deformable bodies is the method of differential equations. ... They express mathematically the physical concept of contiguous action. Einstein's Theory of Relativity”

“Psychology should be the chief basic science upon which the practices of education depend. It should have supplied education with the information it needs concerning the processes of understanding, learning, and thinking, among other things. One of the difficulties has been that such theory as has been developed has been based primarily upon studies of behavior of rats and pigeons. As someone has said, some of the theory thus developed has been an insult even to the rat.”

“Yet the widespread planetary theories, advanced by Ptolemy and most other astronomers, although consistent with the numerical data, seemed likewise to present no small difficulty. For these theories were not adequate unless they also conceived certain equalizing circles, which made the planet appear to move at all times with uniform velocity neither on its deferent sphere nor about its own epicycle's center.”

“It is easier taking the beaten path than making our way over bogs and precipices. The great difficulty in philosophy is to come to every question with a mind fresh and unshackled by former theories, though strengthened by exercise and information.”

“I have a name for people who went to the extreme efficient market theory-which is "bonkers". It was an intellectually consistent theory that enabled them to do pretty mathematics. So I understand its seductiveness to people with large mathematical gifts. It just had a difficulty in that the fundamental assumption did not tie properly to reality.”

“Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.”

“We were an ill-matched pair, my husband and I, from the very outset; he, with very high ideas of a husband's authority and a wife's submission, holding strongly to the 'master-in-my-own-house theory,' thinking much of the details of home arrangements, precise, methodical, easily angered and with difficulty appeased.”

“To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.”

“In less than eight years "The Origin of Species" has produced conviction in the minds of a majority of the most eminent living men of science. New facts, new problems, new difficulties as they arise are accepted, solved, or removed by this theory; and its principles are illustrated by the progress and conclusions of every well established branch of human knowledge.”

“Difficulties arise when reported observations seem to conflict with 'facts' that the majority of scientists accept as established and immutable. Scientists tend to reject conflicting observations.....Nevertheless, the history of science shows that new observations and theories can eventually prevail.”

“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.”

“What makes the theory of relativity so acceptable to physicists in spite of its going against the principle of simplicity is its great mathematical beauty. This is a quality which cannot be defined, any more than beauty in art can be defined, but which people who study mathematics usually have no difficulty in appreciating.”
