Rydberg constant
In spectroscopy, the Rydberg constant, symbol "R" for heavy atoms or "R" for hydrogen, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to the electromagnetic spectra of an atom. The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later showed that its value could be calculated from more fundamental constants via his Bohr model. , "R" and electron spin "g"-factor are the most accurately measured physical constants.
Gene Hiser
He was born in Baltimore, Maryland. He attended college at the University of Maryland, where he played on the baseball team.
Planck constant
Niels Bohr introduced the first quantized model of the atom in 1913, in an attempt to overcome a major shortcoming of Rutherford's classical model. In classical electrodynamics, a charge moving in a circle should radiate electromagnetic radiation. If that charge were to be an electron orbiting a nucleus, the radiation would cause it to lose energy and spiral down into the nucleus. Bohr solved this paradox with explicit reference to Planck's work: an electron in a Bohr atom could only have certain defined energies En
Henry Thacker
Henry Thacker attended Boys' High School and then Canterbury College (what is now known as the University of Canterbury), from where he graduated with a Bachelor of Arts. He then enrolled at Edinburgh University where he gained his M.B. and C.M. diplomas in 1895. Two years later he gained a fellowship in the Royal College of Surgeons in Dublin.
Niels Bohr
Bohr founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, which opened in 1920. Bohr mentored and collaborated with physicists including Hans Kramers, Oskar Klein, George de Hevesy, and Werner Heisenberg. He predicted the existence of a new zirconium-like element, which was named hafnium, after the Latin name for Copenhagen, where it was discovered. Later, the element bohrium was named after him.
Igerna Sollas
Igerna Sollas was born 16 March 1877 in the town of Dawlish at Devon, the daughter of geologist William Johnson Sollas and his first wife Helen. She received an early education at Alexandra School and College in Dublin, and then attended Newnham College, Cambridge on a Gilchrist scholarship in 1897, where she took first class honours in both part I and part II of the Natural Sciences Tripos exam, completing a zoology degree in 1901. She held the position of lecturer in zoology at Newnham from 1903 to 1913, save for the period 1904 to 1906 when she was a Newnham college research fellow.
Paul Sophus Epstein
Paul Sophus Epstein (Warsaw, then part of Imperial Russia, now Poland, March 20, 1883 – Pasadena, February 8, 1966) was a Russian-American mathematical physicist. He was known for his contributions to the development of quantum mechanics, part of a group that included Lorentz, Einstein, Minkowski, Thomson, Rutherford, Sommerfeld, Röntgen, von Laue, Bohr, de Broglie, Ehrenfest and Schwarzschild.
History of science
In 1938 Otto Hahn and Fritz Strassmann discovered nuclear fission with radiochemical methods, and in 1939 Lise Meitner and Otto Robert Frisch wrote the first theoretical interpretation of the fission process, which was later improved by Niels Bohr and John A. Wheeler. Further developments took place during World War II, which led to the practical application of radar and the development and use of the atomic bomb. Though the process had begun with the invention of the cyclotron by Ernest O. Lawrence in the 1930s, physics in the postwar period entered into a phase of what historians have called "Big Science", requiring massive machines, budgets, and laboratories in order to test their theories and move into new frontiers. The primary patron of physics became state governments, who recognized that the support of "basic" research could often lead to technologies useful to both military and industrial applications. Currently, general relativity and quantum mechanics are inconsistent with each other, and efforts are underway to unify the two.
Niels Bjerrum
Niels Bjerrum was the son of ophthalmologist Jannik Petersen Bjerrum, and started to study at University of Copenhagen in 1897. He received his Master's degree in 1902 and his Doctor's degree in 1908, and did research in coordination complex chemistry under Sophus Mads Jørgensen. He became a docent in 1912, and in 1914 he became professor of chemistry at the Royal Agricultural College ("Landbohøjskolen") in Copenhagen, as successor of Odin Tidemand Christensen. He stayed on this post until his retirement in 1949, and from 1939 to 1946 he was also the Director of the College.
Thorn Kief Hillsbery
Thorn Kief Hillsbery is an American novelist. He is the author of "War Boy" and "What We Do Is Secret", which was nominated for a Lambda Literary Award. He was born in Portland, Oregon, and attended Evergreen State College. He currently lives in Manhattan, and teaches a creative writing workshop at Columbia University.
Planck constant
The Bohr magneton and the nuclear magneton are units which are used to describe the magnetic properties of the electron and atomic nuclei respectively. The Bohr magneton is the magnetic moment which would be expected for an electron if it behaved as a spinning charge according to classical electrodynamics. It is defined in terms of the reduced Planck constant, the elementary charge and the electron mass, all of which depend on the Planck constant: the final dependence on h1/2 (r2 > 0.995) can be found by expanding the variables.
Maurice Canning Wilks
Maurice Canning Wilks (1910–1984) was an Irish landscape painter. Born in Belfast in 1910 to a linen designer, he was educated in Belfast at the Malone Public School and attended evening classes at the Belfast College of Art. While attending college he was awarded the Dunville Scholarship allowing him to attend day classes. He went on to exhibit at the Royal Hibernian Academy (RHA) in Dublin where he would one day become an associate member. He was also elected a full member of the Royal Ulster Academy (RUA).
Vallis Bohr
Vallis Bohr is a valley on the Moon stretching due south of the crater Einstein. This wide cleft has a length of about 80 kilometers, and is radial to the Mare Orientale impact basin further to the south. The selenographic coordinates of this feature are .
Copenhagen University Library
The Copenhagen University Library (Danish: Københavns Universitetsbibliotek) in Copenhagen, Denmark, is the main research library of the University of Copenhagen. Founded in 1482, it is the oldest library in Denmark.
Ben Roy Mottelson
He moved to Institute for Theoretical Physics (later the Niels Bohr Institute) in Copenhagen on the Sheldon Traveling Fellowship from Harvard, and remained in Denmark. In 1953 he was appointed staff member in CERN's Theoretical Study Group, which was based in Copenhagen, a position he held until he became professor at the newly formed Nordic Institute for Theoretical Physics (Nordita) in 1957. He was a visiting professor at the University of California, Berkeley in Spring 1959. In 1971 he became a naturalized Danish citizen.
Sundman (crater)
Sundman is a lunar impact crater that lies just past the western limb of the Moon. Although it lies on the far side from the Earth, this part of the surface is brought into view during periods of favorable libration and illumination. Sundman lies to the southwest of the walled plain Einstein, and to the west of the Vallis Bohr cleft. It was named after Finnish mathematician and astronomer Karl F. Sundman.
Morten Helveg Petersen
The son of former Danish foreign minister Niels Helveg Petersen and brother of former minister Rasmus Helveg Petersen, Morten Helveg Petersen grew up in Denmark and in Brussels where he attended the European School, Brussels I from 1974 to 1977. His paternal grandparents were former minister Kristen Helveg Petersen and former mayor of Copenhagen Lilly Helveg Petersen. He got a Master of Science degree in economics from the University of Copenhagen in 1992.

Class reunion
A class reunion is a meeting of former classmates, often organized at or near their former school or college by one or more class members. It is scheduled near an anniversary of their graduation, e.g. every 5 years. Their teachers and administrators may be invited. Those attending reminisce about their student days and bring each other up to date on what has happened since they last meet.
