„An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.“

—  Max Planck, Context: Experimenters are the schocktroops of science… An experiment is a question which science poses to Nature, and a measurement is the recording of Nature’s answer. But before an experiment can be performed, it must be planned – the question to nature must be formulated before being posed. Before the result of a measurement can be used, it must be interpreted – Nature’s answer must be understood properly. These two tasks are those of theorists, who find himself always more and more dependent on the tools of abstract mathematics. Scientific Autobiography and Other Papers (1949)

„Natural science does not simply describe and explain nature; it is part of the interplay between nature and ourselves; it describes nature as exposed to our nature of questioning.“

—  Werner Heisenberg German theoretical physicist 1901 - 1976
Context: [I]n the Copenhagen interpretation of quantum theory we can indeed proceed without mentioning ourselves as individuals, but we cannot disregard the fact that natural science is formed by men. Natural science does not simply describe and explain nature; it is part of the interplay between nature and ourselves; it describes nature as exposed to our nature of questioning. This was a possibility of which Descartes could not have thought, but it makes a sharp separation between the world and the I impossible. If one follows the great difficulty which even eminent scientists like Einstein had in understanding and accepting the Copenhagen interpretation... one can trace the roots... to the Cartesian partition.... it will take a long time for it [this partition] to be replaced by a really different attitude toward the problem of reality. <!--p. 81

Quote from 'The History of Landscape Painting,' fourth lecture, Royal Institution (16 June 1836), from John Constable's Discourses, ed. R.B. Beckett, (Ipswich, Suffolk Records Society, 1970), p. 69.

„All the knowledge we have of nature depends upon facts; for without observations and experiments our natural philosophy would only be a science of terms and an unintelligible jargon.“

—  John Theophilus Desaguliers French-born British natural philosopher and clergyman 1683 - 1744
Context: All the knowledge we have of nature depends upon facts; for without observations and experiments our natural philosophy would only be a science of terms and an unintelligible jargon. But then we must call in Geometry and Arithmetics, to our Assistance, unless we are willing to content ourselves with natural History and conjectural Philosophy. For, as many causes concur in the production of compound effects, we are liable to mistake the predominant cause, unless we can measure the quantity and the effect produced, compare them with, and distinguish them from, each other, to find out the adequate cause of each single effect, and what must be the result of their joint action. p. v: Preface
