Evolution of the Solar System

Rate this book
The present analysis of the origin and evolution of the solar system represents a fusion of two initially independent approaches to the problem. One of us (Alfven) started from a study of the physical processes (1942, 1943a, 1946; summarized in a monograph in 1954), and the other (Arrhenius) from experimental studies of plasma-solid reactions and from chemical and mineralogical analyses of meteorites and lunar and terrestrial samples. Joined by the common belief that the complicated events leading to the present structure of the solar system can be understood only by an integrated chemical-physical approach, we have established a collaboration at the University of California, San Diego (UCSD), in La Jolla, during the last seven years. Our work, together with that of many colleagues in La Jolla, Stockholm, and elsewhere, has resulted in a series of papers describing the general principles of our joint approach, experimental results, and model approximations for some of the most important processes. The present volume is a summary of our results, which we have tried to present in such a form as to make the physics understandable to chemists and the chemistry understandable to physicists. Our primary concern has been to establish general constraints on applicable models. Hence we have avoided complex mathematical treatment in cases where approximations are sufficient to clarify the general character of the processes.

Swedish physicist Hannes Olof Gösta Alfvén won a Nobel Prize of 1970 for his theories on plasma physics.

This electrical engineer and winner for his work on magnetohydrodynamics. He described the now known class of magnetohydrodynamics waves. People originally trained him as an electrical power engineer, and he later moved to research and teaching in the fields. Alfvén made many contributions, including theories, describing the behavior of aurorae, the van Allen belts of radiation, the effect of storms on the field of Earth, the terrestrial magnetosphere, and the dynamics in the Milky Way.

Alfvén received his Philosophiae Doctor from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves."

In 1934, Alfvén taught at the University of Uppsala and the later renamed Manne Siegbahn institute in Stockholm. In 1940, he served as professor of electromagnetic theory and measurements at the royal institute of technology in Stockholm. In 1945, he acquired the non-appointive position of chair of electronics. From 1954 to 1955, Alfvén served as a James William Fulbright scholar at the University of Maryland in College Park. People changed his title to chair in 1963. He left, spent time in the Soviet Union, and afterward in 1967 moved to the United States. Alfvén worked in the departments of electrical engineering at the University of California in San Diego and the University of Southern California.

In 1991, Alfvén retired as professor of electrical engineering at the University of California in San Diego and at the royal institute of technology in Stockholm.

Alfvén spent his later adult life, alternating between California and Sweden.

With a good sense of humor, Alfvén participated in a variety of social issues and worldwide disarmament movements. With a longstanding distrust of computers. Alfvén studied the history of science, Oriental philosophy, and religion. Alfven viewed as a critical irreligious atheist. He spoke English, German, French, and Russian, and some Spanish and Chinese. He expressed great concern about the difficulties of permanent high-level radioactive waste management. Problems in cosmology and all aspects of aurorae also interested Alfvén, who used Das Phänomen des Polarlichts , well-known book of Wilfried Schröder. People published Letters of Alfvén, Treder, and Schröder on the occasion of seventieth birthday of Hans Jürgen Treder. Wilfried Schröder published a long paper on changes in auroral theories in honor of eightieth birthday of Hannes Alfvén in the German scientific journal Gerlands Beiträge zur Geophysik in 1988. Schröder discussed the relationships with Hans-Jürgen Treder and Hannes Alfvén in detail in his publications.

Kerstin Alfvén, a wife, married Hannes Alfvén for 67 years. They reared one boy and four girls. His son served as a physician, while one daughter wrote, and another daughter served as a lawyer. The composer Hugo Alfvén was uncle of Hannes Alfvén.
