Nuclear bodies. Nuclear bodies (also known as nuclear domains or nuclear dots) are biomolecular condensates, membraneless structures found in the cell nuclei of eukaryotic cells. [1] Nuclear bodies include Cajal bodies, the nucleolus, nuclear speckles (also called splicing speckles), histone locus bodies, and promyelocytic leukemia protein (PML ...
Yakov Borisovich Zeldovich ForMemRS [1] (Russian: Я́ков Бори́сович Зельдо́вич, Belarusian: Я́каў Бары́савіч Зяльдо́віч; 8 March 1914 – 2 December 1987), also known as YaB, [2] D.N. was a leading Soviet physicist of Belarusian origin, who is known for his prolific contributions in physical cosmology, physics of thermonuclear reactions ...
Arthur Wightman. Cheuk-Yin Wong. John Archibald Wheeler (July 9, 1911 – April 13, 2008) was an American theoretical physicist. He was largely responsible for reviving interest in general relativity in the United States after World War II. Wheeler also worked with Niels Bohr to explain the basic principles of nuclear fission.
Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1] Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales. [2][1] In ...
Diagram illustration the creation of new elements by the alpha process. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang ...
The liquid drop model is one of the first models of nuclear structure, proposed by Carl Friedrich von Weizsäcker in 1935. [5] It describes the nucleus as a semiclassical fluid made up of neutrons and protons, with an internal repulsive electrostatic force proportional to the number of protons. The quantum mechanical nature of these particles ...
t. e. Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to ...
The adoption of the term "nucleus" to atomic theory, however, was not immediate. In 1916, for example, Gilbert N. Lewis stated, in his famous article The Atom and the Molecule , that "the atom is composed of the kernel and an outer atom or shell. " [ 12 ] Similarly, the term kern meaning kernel is used for nucleus in German and Dutch.
