Römer, Flamsteed, Cassini and the Speed of Light
One of Ole Romer's most influential contributions to astronomy was the theory that light has a finite speed, which he calculated from inequalities in the motion of a satellite of Jupiter. The English
Paris 1676: The Discovery of the Velocity of Light and the Roles of Rømer and Cassini
It is often claimed that the 1676 discoveries at the Paris Observatory of a new irregularity in the orbit of Jupiter’s first satellite and of the velocity of light were not due to Rømer alone but
Conjunctions in Paris: Interactions between Rømer and Huygens
Christiaan Huygens (1692–1695) and Ole Romer (1644–1710) closely interacted during the 1670s, when they were both in and around the Academie Royale des Sciences in Paris. They were part of a small
The Search for Stellar Parallaxes and the Discovery of the Aberration of Light: The Observational Proofs of the Earth's Revolution, Eustachio Manfredi, and the ‘Bologna Case’
A groundbreaking step in the history of science was taken in 1728 and 1729 when James Bradley (1693–1762), the Savilian Professor of Astronomy at Oxford, correctly interpreted several aspects of the
The Satellites of Jupiter, from Galileo to Bradley
The satellites of Jupiter are hardly to the forefront of the typical astronomer’s consciousness, despite the remarkable findings of the Voyager mission. Even historians of astronomy tend to pass over
The aim of this paper was to explore the curious change of opinion about the speed of light that occurred around the end of the nineteenth century. Till then light was judged to move according to the
Roemer, Jupiter's Satellites and the Velocity of Light
The paper lists all the predictions and observations of eclipses of Jupiter's satellites 1668-1678 and compares them with modern computations of the these eclipses by J. H. Lieske. We discuss
Ole Rømer's method still on the stage: the study of two bound eclipsing binaries in quintuple system V994 Her
More than three hundred years ago, Ole Romer measured the speed of light only by observing the periodic shifting of the observed eclipse arrival times of Jupiter's moons arising from the varying
Scientific Method, Statistical Method and the Speed of Light
A history on the speed of light up to the time of Michelson's study is presented and the details of a single study allow to place the method of statistics within the larger context of science.
Galileo, Measurement of the Velocity of Light, and the Reaction Times
Analysis of archival material shows that two decades later members of the Florence scientific society Accademia del Cimento followed Galileo guidelines by actually attempting to measure the velocity of light and suggesting improvements, revealing a fundamental difference between Galileo's and Florence academy's methodologies.


The Origin of Fahrenheit's Thermometric Scale
THE scientific world has recently paid tribute to the bicentenary of the death of the renowned German instrument maker, Daniel Gabriel Fahrenheit1, who was born in Danzig in 1686 and died at The
