unusual facts about Lorentz–Lorenz equation


Lorentz–Lorenz equation

The Lorentz–Lorenz equation is named after the Danish mathematician and scientist Ludvig Lorenz, who published it in 1869, and the Dutch physicist Hendrik Lorentz, who discovered it independently in 1878.

The emu-cgs (or "electromagnetic cgs") units are one of several systems of electromagnetic units within the centimetre gram second system of units; others include esu-cgs, Gaussian units, and Lorentz–Heaviside units.

His awards include Fellow of the Royal Society of London; Fellow of the American Academy of Arts and Sciences (Boston); Fellow of the American Physical Society; Fellow of the Institute of Physics (UK); Fellow of the American Association for the Advancement of Science; winner of the Oliver E. Buckley Prize of the American Physical Society (1993); Alfred P. Sloan Foundation Research Fellow (1984–88); Lorentz Chair (2008), and Dirac Medal (2012).

George Barker Jeffery

He is probably best known to the scientifically literate public as the translator of papers by Einstein, Lorentz, and other fathers of relativity theory.

Hendrikus Albertus Lorentz

Hendrikus Albertus Lorentz (Oudewater, 18 September 1871 – Klerksdorp (South Africa), 2 September 1944) was a Dutch explorer in New Guinea and diplomat in South Africa.

History of Firefox

One minor update to Firefox 3.6, version 3.6.4 (code-named Lorentz) is the first minor update to make non-intrusive changes other than minor stability and security fixes.

Kreuger family

Together with his brother Erik Lorentz Kreuger, he also founded a pulp and paper company close to Emån and in 1871 they bought Fredriksdahl Match Manufacturing Co.

Length contraction

Although both FitzGerald and Lorentz alluded to the fact that electrostatic fields in motion were deformed ("Heaviside-Ellipsoid" after Oliver Heaviside, who derived this deformation from electromagnetic theory in 1888), it was considered an ad hoc hypothesis, because at this time there was no sufficient reason to assume that intermolecular forces behave the same way as electromagnetic ones.

Lorentz invariance in loop quantum gravity

Of interest in this connection would be to see whether the LQG analogue of Minkowski spacetime breaks or preserves global Lorentz invariance, and Carlo Rovelli and coworkers have recently been investigating the Minkowski state of LQG using spin-foam techniques.

Lorentz National Park

In 2006, the Minister of Forestry established a managing structure for Lorentz National Park, the Lorentz National Park Bureau with headquarters in Wamena.

Lorentzian

Cauchy distribution, also known as the Lorentz distribution, Lorentzian function, or Cauchy–Lorentz distribution

Modern searches for Lorentz violation

In the Futurama episode "Law and Oracle" (2011), Erwin Schrödinger is pulled over by cops for violating Lorentz invariance, by going 15 miles per hour over the speed of light.

Nestor J. Zaluzec

He developed Lorentz STEM imaging, High Angular Resolution Electron Channeling X-ray Spectroscopy (HARECXS), High Angular Resolution Electron Channeling Electron Spectroscopy (HARECES), Position Resolved Diffraction, as well as his invention of the scanning confocal electron microscope and the π steradian Transmission X-ray Detector, for which he was given the R&D 100 Awards in 2003 and 2010 respectively.

Non-radiative dielectric waveguide

Moreover, the TM field can be derived from a purely longitudinal Lorentz vector potential \underline{A}.

Pare Lorentz

Though the tight budget and his inexperience occasionally showed through in the film, Lorentz's script, combined with Thomas Chalmers's narration and Virgil Thomson's score, made the 30-minute movie powerful and moving.

Planck charge

It is customary in theoretical physics to adopt the Lorentz–Heaviside units (also known as rationalized cgs).

Squeeze mapping

Furthermore, Wolfgang Rindler, in his popular textbook on relativity, used the squeeze mapping form of Lorentz transformations in his demonstration of their characteristic property (see equation 29.5 on page 45 of the 1969 edition, or equation 2.17 on page 37 of the 1977 edition, or equation 2.16 on page 52 of the 2001 edition).

Standard-Model Extension

A key result in the formal theory of Lorentz violation, published by Kostelecký in 2004, is that explicit Lorentz violation leads to incompatibility of the Bianchi identities with the covariant conservation laws for the energy-momentum and spin-density tensors, whereas spontaneous Lorentz breaking evades this difficulty.

In 1989, Alan Kostelecký and Stuart Samuel proved that interactions in string theories could lead to the spontaneous breaking of Lorentz symmetry.

The Plow That Broke the Plains

The original Vanguard LP and its later CD reissue also included a suite from Thomson's score for another Lorentz documentary, The River.
