Hendrik Antoon Lorentz, from Leyden (Holland), presided the conference, whose general theme was the Theory of Radiation and the Quanta. The conference5 was opened with speeches by Lorentz and Jeans, one on Applications of the Energy Equipartition Theorem to Radiation, the other on the Kinetic Theory of Specific Heat according to Maxwell and Boltzmann. In their talks, the authors explored the possibility of reconciling radiation theory with the principles of statistical mechanics within the classical frame. Lord Rayleigh, in a letter read to the...

Soon afterwards, Hendrik Lorentz treated the free electrons as classical distinguishable particles that obey the MaxweU-Boltzmann distribution laws (Lorentz, 1904-1905). 

The name of this gauge refers to the Dutch physicist Hendrik Antoon Lorentz (1853-1928), whereas the gauge was really introduced by the Danish physicist Ludvig Valentin Lorenz who not only introduced this gauge as well as their retarded solutions (91), but also independently developed Maxwell s equations [39].

Incidentally, the Lorenz gauge was proposed by the Danish physicist Ludvig Lorenz, It is often erroneously designated Lorentz gauge, after the more famous Dutch physicist Hendrik Lorentz. In fact, the condition does fulfill the property known as Lorentz invariance.)... 

This Bern Patent Office employee also knew about the dramatic dilemmas of Hendrik Lorentz, which will be discussed shortly. Einstein recalls that there was a clock at a tram stop in Bern. Whenever his tram moved away from the stop, the modest patent office clerk asked himself what the clock would show if the tram had the velocity of light. Other passengers probably read their newspapers, but Einstein had questions that led humanity on new pathways. 

Hendrik Lorentz (1853-1928) was a Dutch scientist and a professor at Leiden. Lorentz was very dose to formuiating the speciai theory of reiativity. ft was pointed out to Lorentz in 1894 that FitzGeraid had pubfished something simifar. He wrote to FitzGeraid, but the fatter repfied that indeed he has sent a haif-page articfe to Science, but he did not know whether they ever published it After this, Lorentz took every opportunity to stress that FitzGeraid was the first to present the idea. 

Pieter Zeeman (1865-1943), Dutch physicist and pro-l sor at the University of Amsterdam. He became interested in the influence of a magnetic field on molecular spectra and discovered a field-induced splitling of the absorption lines in 1896. He shared the Nobel Prize with Hendrik Lorentz for their researches foto the influerK e of magnetism upon raiSation phenomensT in 1902. The eman splitling of star spectra allows us to determine the... 

Heaviside-Lorentz units A system of units for electric and magnetic quantities based upon c.g.s. electrostatic and electromagnetic units. They are the rationalized forms of Gaussian units and, like the latter, are widely used in particle physics and relativity in preference to the S1 units now employed for general purposes in physics. They are named after Oliver Heaviside (1850-1925) and Hendrik Lorentz (1853-1928). 

It was proposed independently by Hendrik Lorentz (1853-1928) and George Fitzgerald (1851-1901) in 1892 to account for the null result of the Michelson-Morley experiment. The contraction was given a theoretical background in Einstein s special theory of relativity. In this theory, an object of length lo at rest in one frame of reference will appear, to an observer in another frame moving with relative velocity v with respect to the first, to have length Ua-i /a,... 

Lorentz-Lorenz equation A relation between the polarizability a of a molecule and the refractive index n of a substance made up of molecules with this polarizability. The Lorentz-Lorenz equation can be written in theforma= (3/4tcA/) [(n -l)/(n + 2)l, where JV is the number of molecules per unit volume. The equation provides a link between a microscopic quantity (the polarizability) and a macroscopic quantity (the refractive index). It was derived using macroscopic electrostatics in 1880 by Hendrik Lorentz and independently by the Danish physicist Ludwig Valentin Lorenz also in 1880. Compare ClAUSIUS-MoSSOTTr EQUATION. 

Hendrik Lorentz indicated that the Galilean transformation represents only one possibility of making the apparent forces vanish, i.e. assuring that A = D. Both constants need not be equal to 1. As it happens that such a generalization is forced by an intriguing experiment performed in 1887. 

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. 

One of the most straightforward and simple types of magnetic spectroscopy is called Zeeman spectroscopy. Its existence was proposed in 1890 by the Dutch physicist Hendrik Lorentz. If atoms were composed of electrical charges, Lorentz said, these charges should be affected by a magnetic field and a change would be noted in the atomic spectrum. In 1896 a student of Lorentz s, Pieter Zeeman, verified this prediction experimentally. For their work, Lorentz and Zeeman shared a 1902 Nobel Prize.
