John D. Barrow
* 29. 11. 1952 London; Professor für Mathematical Sciences, University of Cambridge, England
"Naturwissenschaftler weisen gern nach, daß weithin für unmöglich gehaltene Dinge in Wirklichkeit ohne weiteres möglich sind; Philosophen neigen im Gegenteil mehr dazu, uns zu beweisen, daß durchaus für möglich gehaltene Dinge in Wirklichkeit unmöglich sind."
Die Entdeckung des Unmöglichen. S. 5
"Die Zukunft vorherzusagen ist nicht unsere Stärke. Wettbüros setzen darauf. Astrologen beweisen es."
Die Entdeckung des Unmöglichen. S. 95
"In der Praxis ist die Wissenschaft eher durch die Grenzen behindert, die in den Wissenschaftlern selbst liegen, als durch die grundsätzlichen Grenzen der Erkenntnis"
Die Entdeckung des Unmöglichen. S. 172
"Manche Leute zerbrechen sich den Kopf darüber, wie wir etwas über den Zustand des Universums vor Milliarden von Jahren erfahren können. Das eigentliche Problem besteht jedoch darin, seinen jetzigen Zustand zu erkennen." Die Entdeckung des Unmöglichen. S. 234
"Wissenschaft beruht darauf, daß bestimmte Dinge unmöglich sind."
Die Entdeckung des Unmöglichen. S. 281
Richard Phillips Feynman
11.5. 1918 New York – 15.2. 1988 Los Angeles; 1965 mit J.Schwinger und S.Tomonaga: Nobelpreis für Physik
• "There is always the possibility of proving any definite [well-defined] theory wrong; but notice that we can never proce it right. Suppose that you invent a good guess, calculate the consequences, and discover every time that the consequences you have calculated agree with experiment. The theory is then right? No, it is simple not proved wrong. In the future you could compute a wider range of consequences, there could be a wider range of experiments, and you might then discover that the thing is wrong... We never are definitely right, we can only be sure we are wrong."
• "Another most interesting change in the ideas and philosophy of science brought about by quantum mechanics is this: it is not possible to predict exactly what will happen in any circumstance.... nature, as we understand it today, behaves in such a way that it is fundamentally impossible to make a precise prediction of exactly what will happen in a given experiment. This is a horrible thing; in fact, philosophers have said before that one of the fundamental requisites of science is that whenever you set up the same conditions, the same thing must happen. This is simply not true, it is not a fundamental condition of science. The fact is that the same thing does not happen, that we can only find an average, statistically, as to what happens. Nevertheless, science has not completely collapsed.
• "Philosophers, incidentally, say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong. For example, some philosopher or other said it is fundamental to the scientific effort that if an experiment is performed in, say, Stockholm, and then the same experiment is done in, say, Quito, the same results must occur. That is quite false. It is not necessary that science do that; it may be a fact of experience, but it is not necessary."
Lecture 2, Basic Physics, from the Feynman Lectures on Physics
"Nature doesn't care what anyone thinks."

"As I understand it, the claim is that the less you use homeopathy, the better it works. Sounds plausible to me."

Brian Greene
* 1963 New York, Professor für Physik und Mathematik, Columbia Universität New York
"Biologen sollten aber auch deutlich machen, dass der Begriff Theorie irreführend sein kann. Was in einem wissenschaftlichen Sinne dahinter steckt, ist eine überwältigend fundierte Daten- und Beweislage. In der Öffentlichkeit klingt Theorie zu oft wie Vermutung."
"Komplexität kann aus einfachen Gesetzmäigkeiten entstehen. Das wird oft unterschätzt."
Interview mit Patrick Illinger, SZ, 4.1.2006, S. 9
Godfrey Harold Hardy
7 Februar 1877 Cranleigh – 1 Dezember 1947 Cambridge, britischer MathematikerhardyWikipedia
“There are masses of chess-players in every civilized country—in Russia, almost the whole educated population; and every chess-player can recognize and appreciate a ‘beautiful’ game or problem. Yet a chess problem is simply an exercise in pure mathematics (a game not entirely, since psychology also plays a part), and everyone who calls a problem ‘beautiful’ is applauding mathematical beauty, even if it is a beauty of a comparatively lowly kind. Chess problems are the
hymn-tunes of mathematics.”
A Mathematician's Apology (Canto). 1940, S. 15
“The proof is by reductio ad absurdum, and reductio ad absurdum, which Euclid loved so much, is one of a mathematician's finest weapons. It is a far finer gambit then any chess gambit: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game.”
A Mathematician's Apology (Canto). 1940, S. 19
“The chess problem is the product of an ingenious but very limited complex of ideas, which do not differ from one another very fundamentally and have no external repercussions. We should think in the same way if chess had never been invented, whereas the theorems of Euclid and Pythagoras have influenced thought profoundly, even outside mathematics.”
A Mathematician's Apology (Canto). 1940, S. 22
“... the main defect of the chess problem is plainly its ‘triviality’, and the contrast in this respect mingles with and disturbs any more purely aesthetic judgement.”
A Mathematician's Apology (Canto)
. 1940, S. 29
“I am inclined to think that I could reinforce my argument by appealing to the feelings of chess-players themselves. Surely a chess master, a player of great games and great matches, at bottom scorns a problemist’s purely mathematical art. He has much of it in reserve himself, and can produce it in an emergency: ‘if he had made such and such a move, then I had such and
such a winning combination in mind.’ But the ‘great game’ of chess is primarily psychological, a conflict between one trained intelligence and another, and not a mere collection of small mathematical theorems.” A Mathematician's Apology (Canto), 1940 hardyOnline, S. 30 – Schach Schach
Stephen W. Hawking

„Der größte Feind des Wissens ist nicht die Unwissenheit, sondern die Illusion, wissend zu sein.”

Wer die Quelle zu diesem Zitat kennt, möge sie mir bitte mitteilen.

„Someone told me that each equation I included in the book would halve the sales. I therefore resolved not to have any equations at all. In the end, however, I did put in one equation, Einstein's famous equation, Hawking. I hope that this will not scare off half of my potential readers.”
Im Vorwort zur ersten Ausgabe von A Brief History of Time
„I do not answer God questions.” auf die Frage “Is there a God?”, gestellt bei einem Auftritt Hawkings am Caltech (California Institute of Technology) in Pasadena, 1998
„I don't claim that God doesn't exist. God is the name people give to the reason we are here. But I think that reason is the laws of physics rather than someone with whom one can have a personal relationship. An impersonal God.” – TIME, 15. November 2010, S. 4
Ernest Rutherford
30. 8. 1871 Spring Grove, N.Z. – 19. 10. 1937 Cambridge, Cambridgeshire, England. Nobelpreis für Chemie 1908
„All science is either physics or stamp collecting.”
Robert Serber
14. 3. 1909 Philadelphia – 1. 6. 1997 New York. US-amerikanischer Teilchenphysiker; arbeitete mit J. Robert Oppenheimer an der University of California, Berkeley an der Atombombe
After the war, he employed his talents at synthesis and explanation to gave a well-known series of lectures at the University of California at Berkeley, later distributed in mimeographed form as "Serber Says," to bring experimental physicists up to speed on nuclear theory so they could branch out in new directions in peacetime research.
„Ich träumte, daß ich starb und in den Himmel kam. Der Heilige Petrus führte mich vor Gott, und Gott sagte zu mir: »Du wirst dich nicht an mich erinnern, aber 1947 habe ich in Berkeley deine Vorlesung über Quantenmechanik gehört«.”
CERN Courier, Juli/August 1997, S. 22, zitiert nach John D. Barrow: Die Entdeckung des Unmöglichen. S.47
Ich setze den Traum fort: Und Gott sprach weiter: »Könntest du mir bitte nochmals ein paar Details deiner Vorlesung erklären«
Das erinnert an:
Ein 15-jähriger pickeliger Junge sitzt bei Lampenschein an seinem Ikea-Schreibtisch, die Wände voll mit Postern von Popstars, hautpsächlich Madonna. Er schreibt: „Liebste Madonna, wahrscheinlich wirst du mich nicht kennen, aber ...”
John Archibald Wheeler
* 9. 7. 1911 Jacksonville, Florida – 13.4.2008, US-amerikanischer Physiker
"In a career spanning 7 decades, Wheeler helped explain nuclear fission, established general relativity as an essential part of astrophysics and cosmology, and pioneered the study of quantum gravity. A list of students reads like a who's who in gravitational theory."
"A Life in Science". Science 320:5875, 2008. S. 431

"As the island of our knowledge grows, so does the shore of our ignorance."
