Critique of Einstein’s light-speed postulate
- Physics
- 2019
There is an alternative version of the light-speed constancy postulate which Einstein enunciated in his landmark 1905 paper on relativistic mechanics. The one that he proposed in his work was that…

Is the speed of light in vacuum really constant
- Physics
- 2016
A challenge of modern physics is to develop a theory of Quatum Gravity. Some models elaborated with this purpose predict measurable effects on photon propagation in vacuum. In particular, the quantum…
The Planck Length and the Constancy of the Speed of Light in Five Dimensional Spacetime Parametrized with Two Time Coordinates
- Physics
- 2016
In relativity and quantum field theory, the vacuum speed of light is assumed to be constant; the range of validity of general relativity is determined by the Planck length. However, there has been no…

Direct terrestrial test of Lorentz symmetry in electrodynamics to 10−18
- PhysicsNature communications
- 2015
This work uses ultrastable oscillator frequency sources to perform a modern Michelson–Morley experiment and makes the most precise direct terrestrial test to date of Lorentz symmetry for the photon, constraining LorentZ violating orientation-dependent relative frequency changes.
Direct Terrestrial Measurement of the Spatial Isotropy of the Speed of Light to 10$^{-18}$
- Physics
- 2014
Lorentz symmetry is a foundational property of modern physics, underlying both the standard model of particles and general relativity. It is anticipated that these two theories are merely low energy…
An information theory interpretation of relativistic phenomena
- Physics
- 2012
Analysis of the evolution of optical and electromagnetic theorizing is suggested to demonstrate that the choice of a mechanically compatible model of electromagnetic radiation, as has conventionally underwritten development of the light-speed postulate of special relativity, is inappropriate.
Louis Essen and the Velocity of Light: From Wartime Radar to Unit of Length
- Education
- 2010
Louis Essen (1908–1997), working at the National Physical Laboratory in Teddington, England, was the first scientist to realize that the value for the velocity of light used widely during World War…
Antibody formation in young rabbits immunized with erythrocytes
- MedicineFolia Microbiologica
- 2008
Litters of young rabbits of different ages were immunized with a suspension of foreign erythrocytes and antibodies were formed (demonstrated by haemagglutination) on the fifth day after immunization.

Proposal for a New Æther Drift Experiment
- GeologyNature
- 1955
FURTH1 has recently suggested a repetition of the Michelson–Morley experiment using microwaves and attempting to detect the change in resonant frequency of a cavity as it is rotated through 90°.…

No experiments seem to have been carried out for testing whether such second-order effects could not be detected with standing electromagnetic waves, but the fact that the frequencies of microwaves in the centimetre region can now be measured with extraordinary accuracy, such waves could be used for this purpose with great advantage.

IT has been suggested by H. Littman Furth1 that the Michelson–Morley experiment might be repeated, using microwaves in place of light waves, by measuring the resonant frequency of a cavity with the…
Thermal Treatment of Raney Nickel Catalyst
- ChemistryNature

It is well known that nickel catalyst, which is used in catalytic hydrogenation, is very sensitive to heat. In general, at higher temperatures of the hydrogenation reaction the decrease of catalytic…
