During that time, Fahrenheit met or was in contact with Ole Rømer, Christian Wolff, and Gottfried Leibniz.

According to a letter Fahrenheit wrote to his friend Herman Boerhaave, his scale was built on the work of Ole Rømer, whom he had met earlier.

It is for this reason that normal human body temperature is approximately 98 ° ( oral temperature ) on the revised scale ( whereas it was 90 ° on Fahrenheit's multiplication of Rømer, and 96 ° on his original scale ).

The Danish and German geographical mile ( geografisk mil and geographische Meile or geographische Landmeile, respectively ) is 4 minutes of arc, and was defined as approximately 7421. 5 metres by the astronomer Ole Rømer of Denmark.

An early experiment to measure the speed of light was conducted by Ole Rømer, a Danish physicist, in 1676.

Ole Christensen Rømer (; 25 September 1644, Århus – 19 September 1710, Copenhagen ) was a Danish astronomer who in 1676 made the first quantitative measurements of the speed of light.

Christen Pedersen had taken to using the name Rømer, which means that he was from the Danish island of Rømø, to distinguish himself from a couple of other people named Christen Pedersen.

There are few sources on Ole Rømer until his immatriculation in 1662 at the University of Copenhagen, at which his mentor was Rasmus Bartholin who published his discovery of the double refraction of a light ray by Iceland spar ( calcite ) in 1668, while Rømer was living in his home.

Rømer was given every opportunity to learn mathematics and astronomy using Tycho Brahe's astronomical observations, as Bartholin had been given the task of preparing them for publication.

Rømer was employed by the French government: Louis XIV made him tutor for the Dauphin, and he also took part in the construction of the magnificent fountains at Versailles.

In 1681, Rømer returned to Denmark and was appointed professor of astronomy at the University of Copenhagen, and the same year he married Anne Marie Bartholin, the daughter of Rasmus Bartholin.

In 1705, Rømer was made the second Chief of the Copenhagen Police, a position he kept until his death in 1710.

In Copenhagen, Rømer made rules for building new houses, got the city's water supply and sewers back in order, ensured that the city's fire department got new and better equipment, and was the moving force behind the planning and making of new pavement in the streets and on the city squares.

Rømer presented his results to the French Academy of Sciences, and it was summarised soon after by an anonymous reporter in a short paper,, published 7 December 1676 in the Journal des sçavans.

The Rundetårn ( round tower ) was used in the 17th century as an observatory by Ole Rømer.

The effect of the finite speed of light on observations of celestial objects was first recognised by Ole Rømer in 1675, during a series of observations of eclipses of the moons of Jupiter.

Rømer then saw that the freezing point of pure water was roughly one eighth of the way ( about 7. 5 degrees ) between these two points, so he redefined the lower fixed point to be the freezing point of water at precisely 7. 5 degrees.

Picard collaborated and corresponded with many scientists, including Isaac Newton, Christiaan Huygens, Ole Rømer, Rasmus Bartholin, Johann Hudde, and even his main competitor, Giovanni Cassini, although Cassini was often less than willing to return the gesture.

The family's most prominent member was Nils Henriksson ( died 1523 ), Lord High Steward of Norway, who was married with the famed lady Ingegjerd Ottesdotter Rømer, heiress of Austrått.

Fahrenheit visited him in 1708 and improved on the Rømer scale, the result being the familiar Fahrenheit temperature scale still in use today in a few countries.

After studies in Copenhagen, Rømer joined the observatory of Uraniborg on the island of Hven, near Copenhagen, in 1671.

Leibniz, Domenico Guglielmini ( 1655 — 1710 ), Hartsoeker, and E. W. Tschirnhaus were appointed on 4 February, James Bernoulli and John Bernoulli on 14 February, and Newton and Ole Rømer on 21 February.

Without this postulate it would be impossible to infer the speed of light from astronomical observations, as Ole Rømer did based on observations of the moons of Jupiter.

Already in his philosophical writing on time measurements ( 1898 ) Poincaré wrote that astronomers like Ole Rømer, in determining the speed of light, simply assume that light has a constant speed, and that this speed is the same in all directions.

Without this postulate it would not be possible to infer the speed of light from astronomical observations, as Rømer did based on observations of the moons of Jupiter.

Poincaré went on to note that Rømer also had to assume that Jupiter's moons obey Newton's laws, including the law of gravitation, whereas it would be possible to reconcile a different speed of light with the same observations if we assumed some different ( probably more complicated ) laws of motion.

* Danish astronomer Ole Rømer measures the speed of light by observing the eclipses of Jupiter's moons, obtaining a speed of 140, 000 miles per second ( approximately 25 % too slow ).

Using a telescope, Rømer observed the motions of Jupiter and one of its moons, Io.

If Rømer had known the diameter of the Earth's orbit, he would have calculated a speed of 227, 000, 000 m / s.

In 1700, Rømer managed to get the king to introduce the Gregorian calendar in Denmark-Norway — something Tycho Brahe had argued for in vain a hundred years earlier.

Rømer also developed one of the first temperature scales.

Rømer also established several navigation schools in many Danish cities.

Over a period of several months, Jean Picard and Rømer observed about 140 eclipses of Jupiter's moon Io, while in Paris Giovanni Domenico Cassini observed the same eclipses.

In 1672 Rømer went to Paris and continued observing the satellites of Jupiter as Cassini's assistant.

Rømer added his own observations to Cassini's and observed that times between eclipses ( particularly those of Io ) got shorter as Earth approached Jupiter, and longer as Earth moved farther away.
