Extractions: March 10, 1997 r. Edward M. Purcell, who made it possible to "listen" to the whisperings of hydrogen throughout the universe, died Friday in Cambridge, Mass. He was 84. The cause was respiratory failure, a son said. Purcell had been associated with Harvard University since 1936, retiring from there in 1977 as the Gerhard Gade University Professor. In 1952, he shared the Nobel Prize in Physics for discovering a way to detect the extremely weak magnetism of the atomic nucleus. The method, measuring nuclear magnetic resonance, is widely used to study the structure of molecules and to measure magnetic fields. The previous year, he and a graduate student, Harold I. Ewen, used an antenna on a Harvard roof for the first detection of radio emissions from clouds of hydrogen in space. As had been predicted, the emissions were at a wavelength of 21 centimeters, or 8.3 inches. Because hydrogen is the dominant material of the universe, such observations became a prime astronomical tool. As the most prominent landmark in radio astronomy, that wavelength has also been the focus of efforts to detect signals from any civilizations on other worlds. Purcell was a tall, thin man who retained his boyish appearance and diffidence into middle age. On scientific matters, however, he was outspoken, serving as a science adviser to Presidents Dwight D. Eisenhower, John F. Kennedy and Lyndon B. Johnson.

Extractions: American physicist who, for his nuclear magnetic moment studies of liquid and solid helium, shared the 1952 Nobel prize in physics with Bloch . Both men's research led to the development of nuclear magnetic resonance In addition, with Ewen on March 25, 1951, he was one of the first to detect 21 centimeter radiation from the spin-flip transition of neutral hydrogen, predicted by Oort . This detection was soon confirmed in the Netherlands by C. A. Muller and Oort . Purcell is also the author of the classic undergraduate textbook Electricity and Magnetism.

Extractions: Edward Mills Purcell (1912-1997), born in Taylorville, Illinois, shared Nobel Prize in Physics in 1952 with Felix Bloch for their development of new methods for nuclear magnetic precision measurements and discoveries in connection therewith Professor Purcell studied electrical engineering at Purdue University, graduating in 1933. After spending a year as an exchange student at the Technische Hochschule in Karlsruhe, Germany, he obtained his master's and Ph.D. in physics from Harvard University. He became an instructor at Harvard in 1938 and during World War II he was a group leader at the MIT radiation laboratory where radar was being perfected. Purcell studied various subjects such nuclear magnetism, radio astronomy, astrophysics and biophysics, associating with I. I. Rabi and others who had made discoveries concerning the atomic nucleus. Purcell discovered that by using a strong magnetic field and precisely tuned microwaves one can measure nuclear resonance frequency and magnetism. For this he shared the Nobel Prize with Felix Bloch of Stanford.

Extractions: SEARCH THE GAZETTE Colleagues and friends worldwide were saddened by the passing of Edward Mills Purcell, Gerhard Gade University Professor, Nobel Laureate, and giant of 20th century physics. Purcell grew up in the Illinois towns of Taylorville and Mattoon, where his father managed a regional telephone company, and where the youthful Edward discovered the joys of tinkering with discarded telephone equipment. He was inspired also by the elegant articles in the Bell System Technical Journal - "It was a glimpse into some kind of wonderful world where electricity and mathematics and engineering and nice diagrams all came together," he recalled fifty years later. He entered Purdue intending to become an electrical engineer, but by the time he graduated with a BSEE he knew that he was to become a physicist. He spent a year as an exchange student in pre-war Germany, studying physics at Karlsruhe. On the voyage to Europe he met a fellow exchange student, Beth Busser, who became his wife three years later. The return voyage brought him to Harvard, where he earned his Ph.D. under Kenneth Bainbridge, and where he remained throughout his career. During the war Purcell headed the group working on very short wavelength radar at the MIT Radiation Laboratory, where microwave radar was being urgently developed to contribute decisively to the Allied victory. In 1945 Purcell (with Pound and Torrey) observed nuclear magnetic resonance (NMR), in an after-hours experiment while still completing work on the classic 27-volume series of books on radar. Though initially used in physics, NMR has been applied powerfully as an analytic method for elucidating chemical structure and materials properties. The Nobel prize winning discovery is also the basis of medical resonance imaging (or MRI), now routinely used as an elegant and non-invasive diagnostic tool, producing beautifully detailed images of the body's interior.

Extractions: in full EDWARD MILLS PURCELL (b. Aug. 30, 1912, Taylorville, Ill., U.S.d. March 7, 1997, Cambridge, Mass.), American physicist who shared, with Felix Bloch of the United States, the Nobel Prize for Physics in 1952 for his independent discovery (1946) of nuclear magnetic resonance in liquids and in solids. Nuclear magnetic resonance (NMR) has become widely used to study the molecular structure of pure materials and the composition of mixtures. During World War II Purcell headed a group studying radar problems at the Radiation Laboratory of the Massachusetts Institute of Technology, Cambridge. In 1946 he developed his NMR detection method, which was extremely accurate and a major improvement over the atomic-beam method devised by the American physicist Isidor I. Rabi. Purcell became professor of physics at Harvard University in 1949 and in 1952 detected the 21-centimetre-wavelength radiation emitted by neutral atomic hydrogen in interstellar space. Such radio waves had been predicted by the Dutch astronomer H.C. van de Hulst in 1944, and their study enabled astronomers to determine the distribution and location of hydrogen clouds in galaxies and to measure the rotation of the Milky Way. In 1960 Purcell became Gerhard Gade professor at Harvard, and in 1980 he became professor emeritus. The same year he received the National Medal of Science.
Extractions: 1945 yýlýnda nükleer manyetik rezonansý keþfi nedeniyle Nobel Fizik Ödülüne layýk görülen, Harvard Üniversitesi fizik profesörlerinden Edward Mills Purcell, 7 Mart 1997 Cuma günü 84 yaþýnda öldü. Purcell'in keþfi, insan vücudunun ayrýntýlý týbbi görüntülerinin, hatta uzak galaksilerin haritalarýnýn elde edilmesini olanaklý kýlmýþtý. Purcell, 1952 Nobel Fizik Ödülünü Stanford Üniversitesi'nden Felix Bloch ile paylaþtý. Bloch ve Purcell, atom çekirdeklerindeki manyetik alaný birbirlerinden baðýmsýz olarak keþfetmiþlerdi. Purcell ve Bloch, hidrojen, fosfor, sodyum vb gibi tek sayýlý proton ve nötronlara sahip çekirdeklerin, spinleri olduðunu ve bunun da, çok küçük bir mýknatýs gibi davranan minik manyetik alanlar yarattýðýný buldular. Manyetik Rezonans görüntüleme, ya da diðer adýyla MRI, bu ilkeyi kullanarak çalýþýyor: Güçlü manyetik alan, radyo dalgalarý ve bilgisayarlar yardýmýyla insan vücudundaki hidrojen haritasýnýn ayrýntýlý görüntüleri elde ediliyor. 1951 yýlýnda Purcell ve arkadaþlarýnca bulunan, hidrojen atomlarýnýn saldýðý radyo dalgalarý, radyoastronomlara galaksilerin haritasýnýn çýkarýlmasýnýn da anahtarýný verdi. Bugün bu haritalama iþlemi için radyoastronomlar hidrojen atomunun 21 cm dalgaboylu salýným frekansýný kullanýyorlar. II. Dünya Savaþý yýllarýnda, MIT Iþýným Laboratuvarý'nda ileri bir mikrodalga radarý geliþtiren grubun baþýnda olan Purcell daha sonralarý da birçok ulusal kuruma danýþmanlýk hizmeti verdi. Purcell'in elektrik ve manyetizma üzerine yazdýðý kitabý da dünyanýn birçok ülkesinde halen üniversite ders kitabý olarak okutuluyor.
