Short Summary
Arnold Sommerfeld was a pioneering German theoretical physicist whose work significantly advanced the development of atomic and quantum physics. He is renowned for his contributions to the theory of electrons in metals and for refining Niels Bohr's model of the atom. Sommerfeld mentored many students who would become prominent physicists, thus shaping future generations in the field. His legacy lies in his influential theories and the impact of his teachings.
Early Life & Education
Arnold Sommerfeld was born on December 5, 1868, in Königsberg, East Prussia, which is now Kaliningrad, Russia. He was raised in a family that valued education, which greatly influenced his academic pursuits. Sommerfeld attended the University of Königsberg, where he initially studied mathematics and physics. He completed his doctorate under the supervision of mathematician Ferdinand von Lindemann in 1891. His early exposure to mathematical rigor and scientific inquiry laid the foundation for his future contributions to theoretical physics. During his educational journey, he was deeply influenced by the works of classical physicists and mathematicians, which steered him toward his future endeavors in atomic theory.
Career Highlights
Sommerfeld's career was marked by significant milestones in theoretical physics. He began as a lecturer at the University of Göttingen, where he collaborated with mathematician Felix Klein. In 1906, he was appointed as a professor of theoretical physics at the University of Munich, a position he held for over three decades. During this time, he worked on extending Niels Bohr's atomic model by introducing elliptical orbits, thus integrating quantum numbers. His work in the quantum theory of metals and the development of the Sommerfeld-Wilson quantization rules are critical milestones in his career. Sommerfeld's influence extended through his mentorship of many future Nobel laureates.
