“Newton's three laws of motion are less a product of novel experiments than of the attempt to reinterpret well-known observations in terms of motions and interactions of primary neutral corpuscles” — Thomas S. Kuhn Copy Share Image
“the process of learning a theory depends upon the study of applications, including practice problem-solving both with a pencil and paper and with instruments in the laboratory. If, for example, the student of Newtonian dynamics ever discovers the meaning of… — Thomas S. Kuhn Copy Share Image

“Gravity, interpreted as an innate attraction between every pair of particles of matter, was an occult quality in the same sense as the scholastics'… — Thomas S. Kuhn Copy Share Image
“Observation and experience can and must drastically restrict the range of admissible scientific belief, else there would be no science. But they cannot alone… — Thomas S. Kuhn Copy Share Image
“We noted in Section II that an increasing reliance on textbooks or their equivalent was an invariable concomitant of the emergence of a first… — Thomas S. Kuhn Copy Share Image
“And even when the apparatus exists, novelty ordinarily emerges only for the man who, knowing with precision what he should expect, is able to… — Thomas S. Kuhn Copy Share Image
“The competition between paradigms is not the sort of battle that can be resolved by proofs.” — Thomas S. Kuhn Copy Share Image
