  • Stephen Hawking

    According to ISNA, the British physicist Stephen Hawking will visit The Iranian Institute for Studies in Theoretical Physics and Mathematics in the Iranian month of Teer (June-July 2007).

    The 65-year old Hawking, disabled by amyotrophic lateral sclerosis, has had different contributions to physics, but is mainly known by public for his contributions to the field of black holes. In 2004, he presented a new theory of black hole radiation that contradicted his previous theories.

    British mathematic and physics professor, Stephen Hawking in answer to Iran's Institute for Studies in Theoretical Physics and Mathematics' invitation is to come to Iran.


    This famous scientist is expected to enter Iran in June and will most probably take part in the Esfahan international physics competitions.


    Stephen William Hawking was born on 8 January 1942 in Oxford, England. His parents' house was in north London, but during the Second World War Oxford was considered a safer place to have babies. When he was eight, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father's old college. Stephen wanted to do Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he did Physics instead. After three years and not very much work he was awarded a first class honors degree in Natural Science.


    Stephen then went on to Cambridge to do research in Cosmology, there being no-one working in that area in Oxford at the time. His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After gaining his Ph.D. he became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for the University. It was first held by Isaac Barrow, and then in 1663 by Isaac Newton.


    Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science.


    His many publications include The Large Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel. Stephen Hawking has two popular books published; his best seller A Brief History of Time, and his later book, Black Holes and Baby Universes and Other Essays.


    Professor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and was made a Companion of Honour in 1989. He is the recipient of many awards, medals and prizes and is a Fellow of The Royal Society and a Member of the US National Academy of Sciences.


    Stephen Hawking continues to combine family life (he has three children and one grandchild), and his research into theoretical physics together with an extensive program of travel and public lectures.

    «استفان هاوكينگ»، استاد دانشگاه «كمبريج» و فيزيكدان برجسته معاصر به دعوت پژوهشگاه دانش*هاي بنيادي به ايران مي*آيد.

    «استفان هاوكينگ»، استاد دانشگاه «كمبريج» و دانشمند برجسته معاصر به دعوت پژوهشگاه دانش*هاي بنيادي (مركز تحقيقات فيزيك نظري و رياضيات) تيرماه به ايران مي*آيد.

    وي در مدت سفر به ايران ضمن برگزاري نشست*هاي تخصصي احتمالا در المپياد جهاني فيزيك در اصفهان نيز حضور خواهد يافت.

    گفتني است، استفان ويليامز هاوكينگ در تاريخ 8 ژانويه سال 1942 در شهر اكسفورد در انگليس متولد شد.

    خانه پدري وي در شمال انگليس بود اما در طول جنگ جهاني دوم اكسفورد مكاني امني براي كودكان محسوب مي*شد.

    وقتي او به سن 8 سالگي رسيد خانواده وي به سنت آلبانز شهري در حدود 20 مايلي شمال لندن نقل مكان كردند.

    در سن 11 سالگي استفان به مدرسه سنت آلبانز رفت و سپس به كالج دانشگاه آكسفورد كه كالج قديمي پدرش بود رفت.

    استفان مايل به تحصيل در رشته رياضيات بود اگرچه پدرش پزشكي را ترجيح مي*داد. در كالج دانشگاه رشته رياضيات تدريس نمي*شد بنابراين استفان در عوض رشته فيزيك را انتخاب كرد. پس ازسه سال و در حالي كه كار زيادي انجام نداده بود استفان در رشته علوم طبيعي اولين ديپلم افتخاري را كسب كرد.

    پس از آن استفان براي تحقيقات در رشته كيهان شناسي به كمبريج رفت كه در آن زمان هيچ كس در آكسفورد در اين حوزه فعاليت نمي*كرد. استاد وي دنيس سياما بود اگرچه استفان اميدوار بود كه با فرد هويلي كه در اين رشته در كمبريج كار كرده بود، تحقيقاتش را انجام دهد.

    پس از كسب دكتري استفان به عنوان اولين محقق انتخاب شد و سپس عنوان محقق تخصصي را در كالج گونويل و كايوس به خود اختصاص داد.

    وي پس از ترك موسسه نجوم در سال 1973 به دپارتمان رياضي كاربردي و فيزيك تئوريك رفت و از سال 1979 مقام استادي Lucasian را در رشته رياضيات كسب كرد. اين كرسي در سال 1663 با هزينه* ريويرند هنري لوكاس، يكي از اعضاي پارلمان دانشگاه و به درخواست وي برگزار شد. اين مقام اولين بار نصيب اسحاق بارو و سپس در سال 1669 نصيب نيوتون شد.

    استفان هاوكينگ بر روي قوانين پايه*اي كه كائنات را اداره مي*كنند كار كرده است. وي با همراهي روگر پنروس نشان داد كه تئوري عمومي نسبيت انيشتن كه اشاره به فضا و زمان دارد، نقطه آغازي در پديده بيگ بنگ (انفجار بزرگ) و نقطه پاياني در سياهچاله*ها دارد.

    اين نتايج نشان مي*دهد كه يكي كردن نسبيت عمومي با تئوري كوانتوم امري ضروري است. تئوري كوانتوم يك دستاورد بزرگ علمي ديگر از نيمه اول قرن بيستم است.

    يك نتيجه چنين اتحادي كه وي كشف كرد اين بود كه سياه چاله*ها نبايد كاملا سياه باشند اما بايد پرتوهايي را منتشر كنند و در نهايت از بين رفته و ناپديد مي*شوند. فرض ديگر اين است كه كائنات لبه يا مرزي در زمان تصوري ندارد. اين امر نشان مي*دهد كه روشي كه كائنات بر اساس آن آغاز شده*اند كاملا با قوانين علم تعيين شده است.

    پروفسور هاوكينگ كه 12 ديپلم افتخاري دارد در سال 1982 جايزه CBE را كسب كرده و ديپلم افتخار بعدي را نيز در سال 1989 به خود اختصاص داد. وي تعداد زيادي جايزه، مدال و پاداش دريافت كرده است و محقق انجمن سلطنتي و عضو آكادمي علوم آمريكا است.

      That would be interesting to see in Iran. His personality will probably be very hard to handle for Iranians...'Kheily haaly be halieh' if I have the expression right!

              Famed mathematician Stephen Hawking was rushed to a hospital Monday and was seriously ill, Cambridge University said.

              The university said Hawking has been fighting a chest infection for several weeks, and was being treated at Addenbrooke's Hospital in Cambridge, the university city north of London.

              "Professor Hawking is very ill," said Gregory Hayman, the university's head of communications. "He is undergoing tests. He has been unwell for a couple of weeks."

              Later in the afternoon, Hayman said Hawking was "now comfortable but will be kept in hospital overnight."

              Hawking, 67, gained renown for his work on black holes, and has remained active despite being diagnosed at 21 with ALS, (amyotrophic lateral sclerosis), an incurable degenerative disorder also known as Lou Gehrig's disease.

              For some years, Hawking has been almost entirely paralyzed, and he communicates through an electronic voice synthesizer activated by his fingers.

              Hawking was involved in the search for the great goal of physics — a "unified theory" — which would resolve contradictions between Albert Einstein's General Theory of Relativity, which describes the laws of gravity that govern the motion of large objects like planets, and the Theory of Quantum Mechanics, which deals with the world of subatomic particles.

              "A complete, consistent unified theory is only the first step: our goal is a complete understanding of the events around us, and of our own existence," he wrote in his best-selling book, "A Brief History of Time," published in 1988.

              In a more accessible sequel "The Universe in a Nutshell," published in 2001, Hawking ventured into concepts like supergravity, naked singularities and the possibility of a universe with 11 dimensions.

              He announced last year that he would step down from his post as Lucasian Professor of Mathematics, a title once held by the great 18th-century physicist Isaac Newton. However, the university said Hawking intended to continue working as Emeritus Lucasian Professor of Mathematics.

              Hawking had canceled an appearance at Arizona State University on April 6 because of his illness.

              "Professor Hawking is a remarkable colleague. We all hope he will be amongst us again soon," said Professor Peter Haynes, head of the university's Department of Applied Mathematics and Theoretical Physics.
