Department Of Physics, Lund University
The Department of Physics in Lund is a department that belongs to both the Faculty of Natural Sciences and the Faculty of Engineering at Lund University. The main goals are to expand the understanding of physics, its applications and to share scientific progress to new generations. Research is conducted in most of the physics subdivisions. The department also offers courses and a Masters's degree programs in pure physics and provides physics education for the Master of Science in Engineering programs. History In 1666 Lund University was founded without a faculty of science, so the physics research was conducted under the faculty of philosophy. In addition, during its first 150 years the University had no professorship in pure physics, so the teachings was instead given by professors in mathematics. There were however a course in experimental physics from the early 18th century, but that course was given by a professor in theoretical medicine; Kilian Stobæus was appointed a ...

Nuclear Physics
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 applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Carl Hellmuth Hertz
Carl Hellmuth Hertz (also written Carl Helmut Hertz, October 15, 1920 – April 29, 1990) was a German physicist known primarily for being involved in the development of inkjet technology and ultrasound technology. He was the son of Gustav Ludwig Hertz and great nephew of Heinrich Hertz. Biography Hellmuth Hertz was born October 15, 1920 in Berlin, Germany. His father was Gustav Hertz who, along with James Franck, was awarded the Nobel Prize in Physics 1925 for their experiments on inelastic electron collisions in gases. Gustav Hertz's uncle was in turn Heinrich Hertz, who first conclusively proved the existence of the electromagnetic waves. Hellmuth graduated from the elite Schule Schloss Salem boarding school in 1939 at the age of 19 years with the highest grade in mathematics and physics. The same year, he was conscripted into the German Army (Wehrmacht) and served as a soldier for Nazi Germany in World War II. In 1943 he was captured in the North African theatre by US ...

Fråga Lund
''Fråga Lund'' (English: ''"Ask Lund"''; Lund being a well-known Swedish university town) is a Swedish television format where professors and other academics sits in a panel, in front of an audience, answering scientific questions. The first show was broadcast in 1962 and have since then existed in many iterations. The latest iteration started in August 2016 with Kristian Luuk as host. History 1962 - 1981 ''Fråga Lund'' was first broadcast in the fall of 1962. It was then Malmö's foremost contribution to Swedish television since Bialitt ended the year before. The first show was recorded in a studio on ''Baltzarsgatan'' (in Malmö, not Lund) and the expert panel consisted of: * Jan-Öjvind Swahn, host of ''Fråga Lund'' (also docent, later professor of ethnology) * Gerhard Bendz, docent, later professor of classical languages) * Sten von Friesen, professor of physics * David H.

Physical Constant
A physical constant, sometimes fundamental physical constant or universal constant, is a physical quantity that is generally believed to be both universal in nature and have constant value in time. It is contrasted with a mathematical constant, which has a fixed numerical value, but does not directly involve any physical measurement. There are many physical constants in science, some of the most widely recognized being the speed of light in a vacuum ''c'', the gravitational constant ''G'', the Planck constant ''h'', the electric constant ''ε''0, and the elementary charge ''e''. Physical constants can take many dimensional forms: the speed of light signifies a maximum speed for any object and its dimension is length divided by time; while the fine-structure constant ''α'', which characterizes the strength of the electromagnetic interaction, is dimensionless. The term ''fundamental physical constant'' is sometimes used to refer to universal-but-dimensioned physical constants su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rydberg Formula
In atomic physics, the Rydberg formula calculates the wavelengths of a spectral line in many chemical elements. The formula was primarily presented as a generalization of the Balmer series for all atomic electron transitions of hydrogen. It was first empirically stated in 1888 by the Swedish physicist Johannes Rydberg, then theoretically by Niels Bohr in 1913, who used a primitive form of quantum mechanics. The formula directly generalizes the equations used to calculate the wavelengths of the hydrogen spectral series. History In 1880, Rydberg worked on a formula describing the relation between the wavelengths in spectral lines of alkali metals. He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/''λ'', the inverse of the wavelength) as his unit of measurement. He plotted the wavenumbers (''n'') of successive lines in each series against consecutive integers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Rydberg
Johannes (Janne) Robert Rydberg (; 8 November 1854 – 28 December 1919) was a Swedish physicist mainly known for devising the Rydberg formula, in 1888, which is used to describe the wavelengths of photons (of visible light and other electromagnetic radiation) emitted by changes in the energy level of an electron in a hydrogen atom. Biography Rydberg was born 8 November 1854 in Halmstad in southern Sweden, the only child of Sven Rydberg and Maria Anderson Rydberg. When he was 4 years old his father died, and the family was forced to live on a small income. In 1873 he graduated from Halmstads elementärläroverk, where he received high grades in maths and physics. Later that year he enrolled in Lund University, and two years later he was awarded his bachelor's degree. In 1879 he was awarded his Doctor of Philosophy with his dissertation "Konstruktioner af kägelsnitt i 3- och 4-punktskontakt". Rydberg began his career as an amanuensis in the institution. He became a docent i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray Spectroscopy
X-ray spectroscopy is a general term for several spectroscopic techniques for characterization of materials by using x-ray radiation. Characteristic X-ray spectroscopy When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy which it previously gained by the excitation is emitted as a photon which has a wavelength that is characteristic for the element (there could be several characteristic wavelengths per element). Analysis of the X-ray emission spectrum produces qualitative results about the elemental composition of the specimen. Comparison of the specimen's spectrum with the spectra of samples of known composition produces quantitative results (after some mathematical corrections for absorption, fluorescence and atomic number). Atoms can be excited by a high-energy beam of charged particles such as electrons (in an electron microscope for example), protons (se ...
