Somerfield ( / ˈsʌmərfiːld / ;) was a chain of small to medium-sized supermarkets operating in the United Kingdom. The business started life in the 19th century as grocers J. H. Mills, and after a series of buyouts and mergers, the company became known as Gateway.
Jul 24, 2017 · Sommerfeld made major contributions to the field of mathematical diffraction theory, although his most important legacy is what is known as Sommerfeld’s atomic model. In 1915, Sommerfeld developed his own version of Niels Bohr’s atomic model (published two years earlier). Although Bohr’s model worked for the hydrogen atom –that is, an ...
Dec 4, 2020 · Sommerfield‘s Quantum Theory. In 1928, Sommerfield suggested that electron gas should be treated quantum mechanically in the light of Pauli's exclusion principle which states that no two particles can have all the quantum numbers identical. He used Fermi-Dirac statistics rather than Maxwell-Boltzmann statistics and succeeded in explaining ...
Nov 16, 2023 · His model, known as Sommerfeld's theory, had a significant impact on solid-state physics and electronics. Contributions to the atomic model. Sommerfeld's atomic model, developed in the early 20th century, expanded on Bohr's model by introducing significant modifications to the description of the structure of atoms.
Arnold Johannes Wilhelm Sommerfeld, ForMemRS [1] ( German: [ˈzɔmɐˌfɛlt]; 5 December 1868 – 26 April 1951) was a German theoretical physicist who pioneered developments in atomic and quantum physics, and also educated and mentored many students for the new era of theoretical physics.
Lived 1868 - 1951. Arnold Sommerfeld is one of the pioneers of quantum and atomic physics. He was a brilliant German theoretical physicist who also educated many students in physics. He is known for introducing the azimuthal quantum number (2nd quantum number) and the spin quantum number (4th quantum number). He also pioneered the X-ray.

Apr 22, 2024 · Arnold Sommerfeld (born Dec. 5, 1868, Königsberg, Prussia [now Kaliningrad, Russia]—died April 26, 1951, Munich) was a German physicist whose atomic model permitted the explanation of fine-structure spectral lines. After studying mathematics and science at Königsberg University, Sommerfeld became an assistant at the University of Göttingen ...
