Relativity Timelines
1638: Descartes (1596-1650) publishes the 'Dioptrics'. He presented an
idea of the ether as the carrier of light.
1678: Huygens (1629-1695) explains reflection, refraction and double
refraction of light as consistent with the wave theory of light.
1801: Young (1773-1829) adds interference to the evidence in favour of
the wave theory. (Bakerian Lecture 12/11/1801 Royal Society of London:
'The Theory of Light and Colours')
1817: Fresnel (1788-1827) and Arago (1786-1853) conclude that light
must travel via transverse waves following their experiments with
polarisation.
1821: Fresnel (1788-1827) publishes a paper confirming that light is a
transverse wave.
1842: Doppler (1803-1853) presented the paper 'On the coloured light
of the double stars and certain other stars of the
heavens' (C.Doppler: 'Über das farbige Licht der Doppelsterne und
einiger anderer Gestirne des Himmels', Abh.königl.böhm.Ges.Wiss. 2,
465-482, 1843). It defined the Doppler Effect, a principle according
to which the motion of source and observer affect the speed of light
and sound.
1873: Maxwell (1831-1879) publishes the 'Treatise on Electricity and
Magnetism'. He is the first scientist to propose the constancy of
light. His electrodynamic formulas, known as Maxwell’s equations,
incorporate c as a constant i.e. c=1/sqrt(KeKh) where Ke is the
electric field constant and Kh is the magnetic field constant.
1878: Maxwell (1831-1879) writes an article for Encyclopaedia
Britannica in which he describes how light is propagated as a
transverse wave and transmitted by the ether. In the article, he
suggests an experiment to determine the velocity of the earth through
the ether by splitting a ray of light and sending the two resulting
rays at right angles to each other. If reflected and recombined, they
should visibly interfere.
1881: Michelson (1852-1931) conducts the experiment suggested by
Maxwell by using an interferometer. He reports after the experiment:
'….The interpretation of these results is that there is no
displacement of the interference bands. ... The hypothesis of the
stationary aether is thus shown to be incorrect.' (A. A. Michelson,
Am. J. Sci, 122, 120; 1881).
1886: Lorentz (1853-1928), believing in the ether, criticises
Michelson's experiment in the paper 'On the Influence of the Earth's
Motion on Luminiferous Phenomena'.
1887: Michelson (1852-1931) and Morley (1838-1923) repeat the
experiment, again reporting that no effect of the movement of the
earth through the aether had been found. (A. A. Michelson and E. W.
Morley, Am. J. Sci. 34, 333; 1887).
1887: Voigt (1850–1919) publishes a paper 'On Doppler's
Principle' ('Ueber das Doppler'sche Prinzip', Nachr. Ges. Wiss.
Goettingen 2, 1887). The paper contains the Voigt transformations. In
modern notation they were:
x' = x - vt, y' = y/g, z' = z/g, t' = t - vx/c2
g = gamma = sqrt(1-vv/cc)
Multiplying the right-hand sides of the equations by g give the
Lorentz transformations.
Voigt corresponds in 1887 and 1888 with Lorentz about the Michelson-
Morley experiment.
1888: Oliver Heaviside (1850-1925) publishes the contraction formula
that now bears Lorentz's name in "The Electrician".
1889: Hertz (1857-1894) publishes 'About basic equations of the
electrodynamics of moving bodies'. Hertz confirmed by experiments
Maxwells's theory that electromagnetic waves and light are one and the
same phenomenon. He demonstrated that electromagnetic waves can be
emitted from wires into free space. He also modified Maxwell's
equations to allow for the null result of the Michelson-Morley
experiment.
1889: Fitzgerald (1851-1901) publishes a short paper 'The Ether and
the Earth's Atmosphere', Science, 13, 390. He points out that the
results of the Michelson-Morley experiment could be explained only if
‘... the length of material bodies changes, according as they are
moving through the ether or across it, by an amount depending on the
square of the ratio of their velocities to that of light’.
1890: Lorentz (1853-1928) publishes 'Electrodynamic basics for moving
bodies' (‘Ueber die Grundlagen der Elektrodynamik für bewegte Körper’,
Ann. Phys. Chem. 15, 478-480, 1890).
1892: Lorentz (1853-1928) publishes 'Maxwell’s electromagnetic theory
applied to moving bodies 'La théorie électromagnétique de Maxwell et
son application aux corps mouvants’, Archives Néerlandaises des
Sciences Exactes et Naturelles.
1892: Lorentz (1853-1928) proposes contraction in a paper ‘The
relative motion of the earth and the ether’ Versl.Kon.Akad.Wetensch.
1, 74.
1897: Larmor, J. (1857-1942) publishes ‘On a dynamical theory of the
electric and luminiferous medium’, Phil. Trans. Roy. Soc. 190, 205–300
(third and last in a series of papers with the same name).
1898: Larmor J. (1857-1942) writes down the 'Lorentz' transformations
in an article and shows that the FitzGerald-Lorentz contraction is a
consequence. He corresponded with Fitzgerald.
1898 Poincare (1854-1912) deals with the issue of simultaneity in his
paper 'Measurement of Time'.
1899: Lorentz (1853-1928) publishes the 'Lorentz' transformations, the
third man to do it (after Voigt and Larmor). His paper describes the
increase of mass, the shortening of length, and the time dilation of a
body moving at speeds close to the velocity of light.
1900: Larmor (1857-1942) publishes 'Aether and Matter' (Cambridge
University Press, New York, 1900).
1900: Poincaré, H. (1854-1912) publishes ‘La theorie de Lorentz et la
Principe de Reaction’, Archives Neerlandaies, V, 253–78.
1902: Lorentz (1853-1928) receives the Nobel prize in Physics.
1903: F. T. Trouton and H. R. Noble publish ‘The mechanical forces
acting on a charged electric condenser moving through space,’ Phil.
Trans. Royal Soc. A 202, 165–181. Unsuccesful attempt to detect motion
of the earth through the ether.
1904: Lorentz (1853-1928) publishes a paper 'Electromagnetic Phenomena
in a System Moving with any Velocity less than that of
Light' (Proceedings of the Academy of Sciences of Amsterdam, 6p. 809,
1904). It contains concepts of ‘Local Time’.
1904: Poincaré (1854-1912) states at the St Louis (USA) exhibition in
1904: '. . . the principle of relativity, according to which the laws
of physical phenomena should be the same, whether for an observer
fixed, or for an observer carried along in a uniform movement of
translation, so that we have not or could not have any means of
discerning whether or not we are carried along in such a motion.'
1904: Lorentz (1853-1928) publishes the paper ‘Electromagnetic
Phenomena in a System Moving with Any Velocity Less than that of
Light’. It is considered the origin of the Lorentz ether theory
(LET).
1905: Lorentz (1853-1928) publishes 'Attempt of a Theory of Electrical
and Optical Phenomena in Moving Bodies' (‘Versuch einer Theorie der
elektrischen und optischen Erscheinungen in bewegten Körpern’).
1905, 5th June: Poincaré (1854-1912) presents his work ‘Sur la
dynamique de l'electron’.
1905, 30th June: Einstein (1879-1955) publishes his first paper on
relativity 'On the Electrodynamics of Moving Bodies' (‘Zur
Elektrodynamik bewegter Koerper’ Annalen der Physik 17:891, 1905).
Einstein gives no references but mentions Maxwell, Hertz, Doppler and
Planck. He states in the footnotes that 'the preceding memoir of
Lorentz was not at this time known to the author'.
1907: Einstein writes in Annalen der Physik: ‘Über eine Möglichkeit
einer Prüfung des Relativitätsprinzips’, ‘Of the possibility of a
verification of the principle of relativity’.
1907: Michelson (1852-1931) receives the Nobel prize in Physics.
1908: Planck (1858-1947) publishes a paper on relativity.
1908: Minkowski (1864-1909) presents a paper (‘Raum und Zeit’) on
relativity expounding the Lorentz equations in tensor form at the
Versammlung Deutscher Naturforscher in Cologne. Later published in
Physikalische Zeitschrift 10 104-111 (1909) and Jahresbericht der
Deutschen Mathematiker-Vereinigung 18 75-88 (1909).
1908/1909: Ritz, W. publishes comments on difficulties with
relativity. 1908: ‘Recherches Critiques Sur L'Electrodynamique
Generale’ Ann. de Chim. et de Phys3, 145 . 1909: ‘La gravitation’
Scientia, 10, 2.
1909: Ritz, W., and A. Einstein publish ‘The Ritz-Einstein Agreement
to Disagree’ Phys. Zeits.,10, 323.
1909: Poincaré (1854-1912) lectures at Goettingen University on
Relativity. He ignores Einstein’s work.

Relativity (SR). He is the author of the Ehrenfest paradox which
covers a problem in relativity. (Phys. Z., 10, 918).
1912: Lorentz (1853-1928) and Einstein (1879-1955) are jointly
recommended by the physicist Wien (1864-1928) for a Nobel prize for
their work on special relativity. Wien: ‘... While Lorentz must be
considered as the first to have found the mathematical content of the
relativity principle, Einstein succeeded in reducing it to a simple
principle. One should therefore assess the merits of both
investigators as being comparable...’.
1913: Georges Sagnac performs a ring interferometry experiment aimed
at observing the correlation of angular velocity and phase-shift. Its
purpose was to detect ‘the effect of the relative motion of the
ether’. He publishes ‘L'ether lumineux demontre par l'effet du vent
relatif d'ether dans un interferometre en rotation uniforme’ in
Comptes Rendus 157 S. 708-710 and ‘Sur la preuve de la réalité de
l'éther lumineux par l'expérience de l'interférographe tournant’ in

both the particle nature of light and for Einstein's Theory of Special
Relativity.
1932: R. J. Kennedy and E. M. Thorndike publish ‘Experimental
Establishment of the Relativity of Time’, Physical Review. Series 2,
vol. 42, p.400-418. Their experiment was a modified form of the
Michelson-Morley experimental procedure. The modification is to make
one arm of the classical Michelson-Morley (MM) apparatus very short.
It served as a test for special relativity to verify time dilation:
according to special relativity, no phase shifts will be detected
while the earth moves around the sun, while such would result from
length contraction alone.

xxein: Most interesting in the timeline. I was always wondering
about how the ideas of Voigt, Larmor, Poincare, Fitzgerald to Lorentz
and Maxwell etc. happened timewise.
So what's your fit with Lorentz-Fitzgerald and gravity? |

Thank you. This is excellent. Please at least add Galileo because of
the principle of relativity.
So, you have claimed Lorentz being the 3rd person to have written down
the Lorentz transform after Voigt and Poincare. Does that mean Voigt
had already done so but discarded it in favor of the Voigt transform? |

Thank you. This is excellent. Please at least add:
** Galileo on his disovery of the principle of relativity.
** Gauss being the first person to conceive the possibility of curved
space.
** Riemann presented (ds^2 = g_ij dq^i dq^j) to describe an invariant
geometry in 3-D.
** Paul Gerber’s ingenious derivation of Mercury’s orbital anomaly.
** The Goettingen group of mathematicians including Klein, Hilbert,
Minkowski, and Schwarzschild being the first to extend Riemann’s
equation into 4-D spacetime.
** Grossmann’s work “entwurf” depended heavily on coordinate
transformation. It did not get anywhere. In doing so, Einstein
abandoned Grossmann like a piece of tissue paper after blowing his
noise into it.
** Einstein’s bragging about deriving Mercury’s orbital anomaly
without the complete set of field equations nor the Schwarzschild
metric.
** Hilbert’s Lagragian to the Einstein-Hilbert action whatever crap
that is.

Perturbation theory, stupid. Ever heard of it?

You don't know what a Lagrangian is? Or are you not able to follow the
derivation of the field equations by varying the action with respect
to the metric tensor?
Just admit you don't understand what you are reading rather than
claiming it is wrong because you don't understand. Would you like to
go through the derivation?

The anomaly is a second order effect of several parts per million.
You must be intoxicated with Einstein’s fermented diarrhea.

I must have posted the derivation to the field equations dozens of
times by now.

xxein: Most interesting in the timeline. I was always wondering
about how the ideas of Voigt, Larmor, Poincare, Fitzgerald to Lorentz
and Maxwell etc. happened timewise.
So what's your fit with Lorentz-Fitzgerald and gravity?
Xxein,
It all started with Doppler in 1842, well before MMX. He defined the
Doppler Effect according to which the frequency of sound waves is
affected by the motion of source and observer. Voigt, after MMX in
1887, wrote about the Doppler Effect and transferred it to what is now
known as the Lorentz transformations. Other physicists besides Lorentz
who had a hand in the final formulation were Heaviside, Larmor and
Fitzgerald.
I believe the Lorentz transformations are not valid. There is no
contraction and time dilation. Voigt’s original work was incorrectly
applied to the motion of physical objects through space to explain the
null result of MMX. However, Michelson and Morley very clearly made a
mistake in calculating the time and distance for light to transit the
parallel arm of the interferometer equipment (refer to my post (c+v+c-
v)/2=c in this NG). In respect of gravity, I have not posted anything
on this yet but will do so in the future.

xxein,
There are not many with humour in this NG. Most take things too
seriously or practise political correctness. Unfortunately it may be
necessary to do so. Thumbs up.
