Theories Quotes

“If your political theory requires humanity to "evolve", then you do not have a theory.... you have a dream.”

“We can measure the fine structure constant with very great precision, but so far none of our theories has provided an explanation of its measured value. One of the aims of superstring theory is to predict this quantity precisely. Any theory that could do that would be taken very seriously indeed as a potential 'Theory of Everything'.”

“It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”

“It's impossible to do science without faith. Sometimes scientists build theories on the premises of faulty assumptions until they discover they were in error and begin again from square one until they discover the true theory. It's quite different with theologians, they build false theory upon false theory until they give you detailed descriptions of heaven and hell and construct dogmas to protect their errors and if you dare say they are in error they condemn you to eternal damnation they arrived at through false theories”

“Dawkins mentioned two mechanisms: the theory of the ‘primeval soup’ and the Cairns-Smith theory. He discussed the latter in some detail. Since no one has computed, for either theory, the chances of the events occurring, Dawkins could not tell us what those chances are. The mechanisms of both theories, however, have every appearance of being very improbably – even to the point of being impossible.”

“In chemistry, our theories are crutches; to show that they are valid, they must be used to walk... A theory established with the help of twenty facts must explain thirty, and lead to the discovery of ten more.”

“...[P]hilosophical theories are structured by conceptual metaphors that constrain which inferences can be drawn within that philosophical theory. The (typically unconscious) conceptual metaphors that are constitutive of a philosophical theory have the causal effect of constraining how you can reason within that philosophical framework.”

“Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant.”

“Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather than introducing it from the start. They believed that if they could find a version of quantum electrodynamics capable of producing the fine structure constant, it would not contain the infinities that marred their theories.”
