Hannes Alfvén |
Hannes Olof Gösta Alfvén (born 30 May 1908 in Norrköping, Sweden; died 2
April 1995 in Djursholm, Sweden) was a Swedish electrical engineer,
plasma physicist and winner of the 1970 Nobel Prize in Physics for his
work on magnetohydrodynamics (MHD). He described the class of MHD waves
now known as Alfvén waves. He was originally trained as an electrical
power engineer and later moved to research and teaching in the fields of
plasma physics and electrical engineering. Alfvén made many
contributions to plasma physics, including theories describing the
behavior of aurorae, the Van Allen radiation belts, the effect of
magnetic storms on the Earth's magnetic field, the terrestrial
magnetosphere, and the dynamics of plasmas in the Milky Way galaxy.
Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves."
In 1934, Alfvén taught physics at both the University of Uppsala and the Nobel Institute for Physics in Stockholm, Sweden. In 1940, he became professor of electromagnetic theory and electrical measurements at the Royal Institute of Technology in Stockholm. In 1945, he acquired the nonappointive position of Chair of Electronics. His title was changed to Chair of Plasma Physics in 1963. In 1954-1955, Alfvén was a Fulbright Scholar at the University of Maryland, College Park. In 1967, after leaving Sweden and spending time in the Soviet Union, he moved to the United States. Alfvén worked in the departments of electrical engineering at both the University of California, San Diego and the University of Southern California.
First and foremost, Alfvén considered himself an electrical engineer. Prior to winning the Nobel Prize, he was not generally recognized as a leading innovator in the scientific community.
The Hannes Alfvén Prize, awarded annually by the European Physical Society for outstanding contributions in plasma physics, is named after him.
Alfvén believed the problem with the Big Bang was that astrophysicists tried to extrapolate the origin of the universe from mathematical theories developed on the blackboard, rather than starting from known observable phenomena. He also considered the Big Bang to be a scientific myth devised to explain creation.
Alfvén and colleagues proposed the Alfvén-Klein model as an alternative cosmological theory to both the Big Bang and steady state theory cosmologies.
Alfvén was married for 67 years to his wife Kerstin. They raised five children, one boy and four girls. His son became a physician, while one daughter became a writer and another a lawyer in Sweden. The composer Hugo Alfvén was Hannes Alfvén's uncle.
