1 day ago · Oppenheimer spoke about the importance of studying the history of science at the dedication of the Niels Bohr Library and Archives of the American Institute of Physics in September 1963. Oppenheimer continued to visit academic institutions throughout his final years. He remained a controversial figure to students, faculty, and communities.
6 hours ago · Bohr considered the structure of a neutral atom to be the result of how it was formed by the successive addition of \(Z\) electrons to a bare nucleus. According to the so-called Aufbauprinzip (construction or building-up principle), the addition of electron number \(p\) to a partially completed atom with \(p-1\) bound electrons would leave the quantum numbers of the \(p-1\) electrons unchanged.

6 hours ago · Bohr, Kramers and Slater, Footnote 44 however, have shown that both these phenomena and the photo-electric effect may be reconciled with the view that radiation proceeds in spherical waves if the conservation of energy and momentum are interpreted as statistical principles. A study of the scattering of individual x-ray quanta and of the recoil electrons associated with them makes possible, however, what seems to be a crucial test between the two views of the nature of scattered x-rays.
6 hours ago · 2 Hydrogen is the Way. The ideas of Planck and Einstein were used by Bohr to build a model of the electronic structure of the atom. Bohr’s father, Christian Bohr (Copenhagen, 1855–Copenhagen, 1911), was a Danish physician and professor at the University of Copenhagen.
6 hours ago · Oskar Benjamin Klein (Mörby, 1894–Stockholm, 1977) was a Swedish physicist who, since 1917, had worked for a few years with Niels Bohr (Copenhagen, 1885–Copenhagen, 1962) at the University of Copenhagen, obtaining his doctorate degree from Stockholm University College in 1921.
1 day ago · Philosophers. v. t. e. In metaphysics, ontology is the philosophical study of being. It investigates what types of entities exist, how they are grouped into categories, and how they are related to one another on the most fundamental level (and whether there even is a fundamental level). [1] Ontologists often try to determine what the categories ...
