Karl Werner Heisenberg citáty strana 2

„První doušek ze sklenice přírodních věd vás změní na ateistu, ale na dně sklenice na vás čeká Bůh.“

„Musíme si uvědomit, že to, co pozorujeme, není příroda sama, ale příroda vystavená naší metodě dotazování.“

„Ideje nejsou zodpovědné za to, co z nich lidé udělají.“

„V diktatuře mohou klást aktivní odpor jen lidé, kteří zdánlivě s režimem spolupracují. Kdo se proti němu vysloví veřejně, ztrácí příležitost k jakémukoliv účinnému odporu.“

„Nejen, že je Vesmír cizí, než si myslíme, je to cizí, než si můžeme myslet.“

Originál: (de) In einer Diktatur kann aktiver Widerstand nur von Leuten ausgeübt werden, die scheinbar beim System mitmachen. Wenn jemand sich öffentlich gegen das System ausspricht, so beraubt er sich damit ganz sicher jeder Möglichkeit eines aktiven Widerstands.

„Přírodní věda nepopisuje a nevysvětluje přírodu; je jen částí hry mezi přírodou a námi.“

“I think that modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language.”

Karl Werner Heisenberg: Citáty anglicky

“In general, scientific progress calls for no more than the absorption and elaboration of new ideas — and this is a call most scientists are happy to heed.”

Das Naturgesetz und die Struktur der Materie (1967), as translated in Natural Law and the Structure of Matter (1981), p. 34

“The atoms in the philosophy of do not move merely by chance. Leucippus seems to have believed in complete determinism, since he is known to have said: "Naught happens for nothing, but everything from a ground and of necessity." The atomists did not give any reason for the original motion of the atoms, which just shows that they thought of a causal description of the atomic motion; causality can only explain later events by earlier events, but it can never explain the beginning.”

Physics and Beyond : Encounters and Conversation (1971)

“Modern positivism…expresses criticism against the naïve use of certain terms… by the general postulate that the question whether a given sentence has any meaning… should always be thoroughly and critically examined. This… is derived from mathematical logic. The procedure of natural science is pictured as an attachment of symbols to the phenomena. The symbols can, as in mathematics, be combined according to certain rules… However, a combination of symbols that does not comply with the rules is not wrong but conveys no meaning.
The obvious difficulty in this argument is the lack of any general criterion as to when a sentence should be considered meaningless. A definite decision is possible only when the sentence belongs to a closed system of concepts and axioms, which in the development of natural science will be rather the exception than the rule. In some case the conjecture that a certain sentence is meaningless has historically led to important progress… new connections which would have been impossible if the sentence had a meaning. An example… sentence: "In which orbit does the electron move around the nucleus?"”

Physics and Philosophy (1958)

“The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.”

But generally the positivistic scheme taken from mathematical logic is too narrow in a description of nature which necessarily uses words and concepts that are only vaguely defined.

“After these conversations with Tagore some of the ideas that had seemed so crazy suddenly made much more sense. That was a great help for me.”

Werner Heisenberg Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik

Initial statement of the Uncertainty principle in "Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik" in Zeitschrift für Physik, 43 (1927) <br class="br">Variant translation: The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa. <br class="br">As quoted in "The Uncertainty Principle" at the American Institute of Physics http://www.aip.org/history/heisenberg/p08.htm

“Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.”

On conversations with Rabindranath Tagore, as quoted in Uncommon Wisdom: Conversations With Remarkable People (1988) by Fritjof Capra, who states that after these "He began to see that the recognition of relativity, interconnectedness, and impermanence as fundamental aspects of physical reality, which had been so difficult for himself and his fellow physicists, was the very basis of the Indian spiritual traditions."
As quoted in Pride of India (2006) by Samskrita Bharati. p. 56
Varianta: After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.

“There is a fundamental error in separating the parts from the whole, the mistake of atomizing what should not be atomized. Unity and complementarity constitute reality.”

"Critique of the Physical Concepts of the Corpuscular Theory" in The Physical Principles of the Quantum Theory (1930) as translated by Carl Eckhart and Frank C. Hoyt, p. 20; also in "The Uncertainty Principle" in The World of Mathematics : A Small Library of the Literature of Mathematics (1956) by James Roy Newman, p. 1051

“There is an enormous difference between modern science and Greek philosophy, and that is just the empiristic attitude… Since the time of Galileo and Newton, modern science has been based upon a detailed study of nature and upon the postulate that only such statements should be made, as have been verified or at least can be verified by experiment. The idea that one can single out some events from nature by an experiment… to find out what is the constant law in the continuous change, did not occur to the Greek philosophers. Therefore, modern science has from its beginning stood on a much more modest, but at the same time much firmer, basis than ancient philosophy. Therefore, the statements of modern physics are in some way meant much more seriously than the statements of Greek philosophy.”

As quoted in Physics from Wholeness : Dynamical Totality as a Conceptual Foundation for Physical Theories (2005) by Barbara Piechocinska.

“Reality is in the observations, not in the electron.”

“The great scientific contribution in theoretical physics that has come from Japan since the last war may be an indication of a certain relationship between philosophical ideas in the tradition of the Far East and the philosophical substance of quantum theory.”

A widely quoted statement by the character Walter White (a.k.a. "Heisenberg"), in the Cornered episode of Breaking Bad (21 August 2011), which people not familiar with the show might conceivably mistake for an attribution to the scientist.
