Frasi di Stephen Hawking
pagina 4

Stephen William Hawking è un fisico, matematico, cosmologo e astrofisico britannico, fra i più importanti e conosciuti fisici teorici del mondo, noto soprattutto per i suoi studi sui buchi neri e l'origine dell'universo. Tra le sue idee più importanti vi sono la radiazione di Hawking, la teoria cosmologica sull'inizio senza confini dell'universo , la termodinamica dei buchi neri e la partecipazione all'elaborazione di numerose teorie fisiche e astronomiche con altri scienziati, come il multiverso, la formazione ed evoluzione galattica e l'inflazione cosmica, tutte teorie da lui spiegate con chiarezza e semplicità anche in numerosi testi di divulgazione scientifica per il grande pubblico.

Condannato all'immobilità dagli anni ottanta a causa di una malattia del motoneurone diagnosticata nel 1963, forse l'atrofia muscolare progressiva o la sclerosi laterale amiotrofica, Hawking è costretto dalla patologia a comunicare con un sintetizzatore vocale. La sua immagine pubblica, complice l'apparizione in molti documentari e trasmissioni televisive, è divenuta una delle icone popolari della scienza moderna, come già accaduto ad Albert Einstein.



Ha occupato la cattedra lucasiana di matematica all'Università di Cambridge per circa trent'anni, dal 1979 al 30 settembre 2009 e tuttora è direttore del Dipartimento di Matematica Applicata e Fisica Teorica di Cambridge. È membro della Royal Society, della Royal Society of Arts, della Pontificia Accademia delle Scienze. Nel 2009 ha ricevuto la Medaglia presidenziale della libertà, la più alta onorificenza degli Stati Uniti d'America, conferita dal presidente Obama.

Stephen Hawking: Frasi in inglese

“Equations are just the boring part of mathematics. I attempt to see things in terms of geometry.”

As quoted in Stephen Hawking: A Biography (2005) by Kristine Larsen, p. 43

“I now predict that I was wrong.”

Attributed in the movie The Theory of Everything (2014)

“[on the possibility of contact with an alien civilization]: I think it would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low.”

Appearance in the National Geographic Channel program Naked Science: Alien Contact, as quoted in The New York Times (24 November 2004) http://query.nytimes.com/gst/fullpage.html?res=9C00E2D8173EF937A15752C1A9629C8B63&sec=&spon= and a CNN transcript of an interview with Seth Shostak from Anderson Cooper 360 (26 November 2004) http://transcripts.cnn.com/TRANSCRIPTS/0411/26/acd.01.html

“There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?”

As quoted in The Anthropic Cosmological Principle (1986) by John D. Barrow and Frank J. Tipler. p. 444

“Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do.”

Interview "Colonies in space may be only hope, says Hawking" by Roger Highfield in Daily Telegraph (16 October 2001) http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2001/10/16/nhawk16.xml&sSheet=/news/2001/10/16/ixhome.html

“All my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them.”

From the 1997 television program Stephen Hawking's Universe http://www.pbs.org/wnet/hawking/html/home.html
Unsourced variant: All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. Perhaps that is why I have sold more books on physics than Madonna has on sex. This quote seems to combine the above sentence from Stephen Hawking's Universe with a statement from the Foreword to The Illustrated Brief History of Time: As Nathan Myhrvold of Microsoft (a former post-doc of mine) remarked: I have sold more books on physics than Madonna has on sex.

“We should seek the greatest value of our action.”

Response to a question on how we should live, in an interview with The Guardian (15 May 2011)

“We are each free to believe what we want and it is my view that the simplest explanation is there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization. There is probably no heaven, and no afterlife either. We have this one life to appreciate the grand design of the universe, and for that, I am extremely grateful.”

Quoted from the Discovery Channel, 15 August 2011.
"Stephen Hawking There is no God. There is no Fate." from episode 1 https://www.youtube.com/watch?v=7L7VTdzuY7Y · [Curiosity: Did God Create the Universe?, http://dsc.discovery.com/tv-shows/curiosity/topics/did-god-create-the-universe.htm, Discovery Communications, LLC., 7 August 2011, 4 July 2013]

“We hold these truths to be self-evident that all P-brains are created equal.”

Stephen Hawking libro The Universe in a Nutshell

The Universe in a Nutshell (2001)

“In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?”

Open question, posted to the Internet, as quoted in The Guardian, and "Watching the World" in Awake! magazine (June 2007); a month after posting the question he explained: I don’t know the answer. That is why I asked the question, to get people to think about it, and to be aware of the dangers we now face.

“The zero-G part was wonderful and the higher-G part was no problem. I could have gone on and on. Space, here I come!”

After completing a zero-gravity flight in a specially modified plane, as quoted in "Hawking takes zero-gravity flight" BBC News (27 April 2007) http://news.bbc.co.uk/1/hi/sci/tech/6594821.stm

“Einstein was confused, not the quantum theory.”

Lecture at the Amsterdam Symposium on Gravity, Black Holes, and String Theory (21 June 1997)

“If you are disabled, it is probably not your fault, but it is no good blaming the world or expecting it to take pity on you. One has to have a positive attitude and must make the best of the situation that one finds oneself in; if one is physically disabled, one cannot afford to be psychologically disabled as well. In my opinion, one should concentrate on activities in which one's physical disability will not present a serious handicap. I am afraid that Olympic Games for the disabled do not appeal to me, but it is easy for me to say that because I never liked athletics anyway. On the other hand, science is a very good area for disabled people because it goes on mainly in the mind. Of course, most kinds of experimental work are probably ruled out for most such people, but theoretical work is almost ideal. My disabilities have not been a significant handicap in my field, which is theoretical physics. Indeed, they have helped me in a way by shielding me from lecturing and administrative work that I would otherwise have been involved in. I have managed, however, only because of the large amount of help I have received from my wife, children, colleagues and students. I find that people in general are very ready to help, but you should encourage them to feel that their efforts to aid you are worthwhile by doing as well as you possibly can.”

"Handicapped People and Science" http://books.google.com/books?id=9LVFAAAAYAAJ&q=%22handicapped+people+and+science%22#search_anchor by Stephen Hawking, Science Digest 92, No. 9 (September 1984): 92 (details of citation from here http://www.enotes.com/stephen-hawking-criticism/hawking-stephen/further-reading).

“I'm not religious in the normal sense. I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.”

Quoted in "Stephen Hawking prepares for weightless flight", New Scientist (26 April 2007) http://www.newscientist.com/article/dn11722-stephen-hawking-prepares-for-weightless-flight.html

“The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological — technologies that flowed directly from advances in basic science.”

From Hawking's article A Brief History of Relativity http://www.time.com/time/magazine/article/0,9171,993018-6,00.html, in Time magazine (31 December 1999)

“If machines produce everything we need, the outcome will depend on how things are distributed. Everyone can enjoy a life of luxurious leisure if the machine-produced wealth is shared, or most people can end up miserably poor if the machine-owners successfully lobby against wealth redistribution. So far, the trend seems to be toward the second option, with technology driving ever-increasing inequality.”
