Stephen Hawking: Citáty o vesmíru

„Pamatujte, dívejte se nahoru na hvězdy, ne dolů na vaše nohy. Snažte se pochopit, co vidíte a přemýšlejte, díky čemu může vesmír existovat.“

Stephen Hawking citát: „Dívejte se vzhůru na hvězdy a nikoli dolů na nohy. Pokuste se pochopit, co vidíte a proč existuje vesmír. Buďte zvědaví.“

„Když přijdete na to, jak funguje vesmír, svým způsobem ho ovládáte.“

Stručná historie mého života

„Ptát se na to, co se stalo před vznikem vesmíru, je totéž, jako se ptát na bod na Zemi o souřadnici 91 stupňů severní šířky, není to zkrátka definováno. Místo toho, abychom říkali, že vesmír byl stvořen a že možná jednou zanikne, bychom měli jen říkat: Vesmír je.“

Originál: (en) 'To ask what happened before the universe began is like asking for a point on the Earth at 91 degrees north latitude; it just is not defined. Instead of talking about the universe begin created, and maybe coming to an end, one should say:"The universe is."

Stephen Hawking citáty a výroky

Stephen Hawking citát: „Všiml jsem si, že lidé, kteří tvrdí, že vše je předurčeno a my na tom nic nemůžeme změnit, se rozhlíží před tím, než přejdou ulici.“

„Když slyším o Schrödingerově kočce, beru do ruky pušku.“

„Úvahy o tom, že černá díra emituje částice, nasvědčují, že Bůh nejenže v kostky hraje, ale občas je hází i tam, kde je nikdo nemůže vidět.“

narážka na Einsteinův výrok
Originál: (en) God not only plays dice but also sometimes throws them were they cannot be seen – namely into a black hole.

„Lidstvo má hlubokou potřebu objevovat, učit se, poznávat. A také jsme společenští tvorové. Je pro nás důležité vědět, jestli jsme ve tmě vesmíru sami.“

Stephen Hawking: Citáty anglicky

“Disorder increases with time because we measure time in the direction in which disorder increases.”

Stephen Hawking kniha A Brief History of Time

Zdroj: A Brief History of Time (1988), Ch. 9
Kontext: Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can’t have a safer bet than that!

“God abhors a naked singularity.”

“Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted.”

"The Quantum State of the Universe", Nuclear Physics (1984) <!-- B239, p. 258 -->
Kontext: Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.

“Women. They are a complete mystery.”

Response when asked what he thinks about most during the day, "Stephen Hawking at 70: Exclusive interview" http://www.newscientist.com/article/mg21328460.500-stephen-hawking-at-70-exclusive-interview.html in New Scientist (4 January 2012)

“The greatest enemy of knowledge is not ignorance. It is the illusion of knowledge.”

Sometimes attributed to Hawking without a source, but originally from historian Daniel J. Boorstin. It appears in different forms in The Discoverers (1983), Cleopatra's Nose (1995), and introduction to The Decline and Fall of the Roman Empire (1995)

“I am discounting reports of UFOs. Why would they appear only to cranks and weirdos?”

As quoted in a TED talk, " Asking Big Questions about the Universe http://www.ted.com/talks/view/id/242"

“I have hardly ever known a mathematician who was able to reason.”

Plato, The Republic, Book VII, 531-E

“Galileo, perhaps more than any other single person, was responsible for the birth of modern science.”

“Science could predict that the universe must have had a beginning.”

Stephen Hawking kniha Black Holes and Baby Universes and Other Essays

Black Holes and Baby Universes and Other Essays (1993)

“Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four.”

As quoted in "Return of the time lord" in The Guardian http://books.guardian.co.uk/departments/scienceandnature/story/0,6000,1579384,00.html (27 September 2005)

“I used to think that information was destroyed in black holes. But the AdS/CFT correspondence led me to change my mind. This was my biggest blunder, or at least my biggest blunder in science.”

"Stephen Hawking at 70: Exclusive interview" http://www.newscientist.com/article/mg21328460.500-stephen-hawking-at-70-exclusive-interview.html in New Scientist, (4 January 2012). In his comment that he "used to think that information was destroyed in black holes", he is referring to the black hole information paradox.

“I regard [the many worlds interpretation] as self-evidently correct. [T. F.: Yet some don't find it evident to themselves. ] Yeah, well, there are some people who spend an awful lot of time talking about the interpretation of quantum mechanics. My attitude — I would paraphrase Goering—is that when I hear of Schrödinger's cat, I reach for my gun.”

Heard in person by this contributor when Hawking showed-up in a Caltech physics class taught by Robert Christy in 1980 or '81; when asked about collapse of the state-vector he whispered to his assistant Chris (surname unknown) something at which point Chris stood up and said 'Stephen is paraphrasing Herman Göring by saying "When I hear the words 'Schrödinger's Cat' I reach for my gun."'.
