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.

Rømer also established several navigation schools in many Danish cities.

# In Touch-Starting from an attempt for cheaper fusion power using superconductivity, which was discovered by Onnes, with liquid gas provided by Louis-Paul Cailletet, who carried out experiments on a tower built by Gustave Eiffel, who also built the Statue of Liberty with its famous poem by the Jewish activist Emma Lazarus, helped by Oliphant, whose boss Elgin was the son of the man who stole the Elgin Marbles and sold them with the help of royal painter Thomas Lawrence, whose colleague Dr. Hunter had an assistant whose wife's lodger was Benjamin Franklin, who charted the Gulf Stream with a thermometer Fahrenheit borrowed from Ole Rømer, whose friend Picard surveyed Versailles and provided the water for the fountains and the royal gardens and all the trees that inspired Duhamel to write the book on gardening that was read by the architect William Chambers, who hired the Scottish stonemason Thomas Telford, whose idea for London Bridge was turned down by Thomas Young, whose light waves travel in ether, as do Hertz's electricity waves, with which Helmholtz prods a frog to disprove the vitalists, whose leader, Klages, analyzes handwriting so individual zip codes have to be capital letters to get your mail to a jungle village to keep you " In Touch ".

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.

The development of today's thermometers and temperature scales began in the early 18th century, when Gabriel Fahrenheit adapted a thermometer using mercury and a scale both developed by Ole Christensen Rømer.

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

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.

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.

* December – Ole Rømer makes the first quantitative measurements of the speed of light.

* 25 September-Ole Rømer, Danish astronomer who makes the first quantitative measurements of the speed of light ( died 1710 )

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.

* 1676 – Ole Rømer measures the speed of light for the first time

Ordinary cycloids were studied by Galileo Galilei and Marin Mersenne as early as 1599 but cycloidal curves were first conceived by Ole Rømer in 1674 while studying the best form for gear teeth.

From May 1, 1683, King Christian V of Denmark introduced an office to oversee weights and measures, a justervæsen, first led by Ole Rømer.

A pendulum definition for the foot was first suggested by Rømer, introduced in 1820, and changed in 1835.

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 ).

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.

( Rømer scale ), The temperature scale used for his thermometer had 0 representing the temperature of a salt and ice mixture ( at about 259 K ).

Rømer is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701.

The symbol for degrees Rankine is ° R ( or ° Ra if necessary to distinguish it from the Rømer and Réaumur scales ).

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.

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.

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

Rømer was born on 25 September 1644 in Århus to a merchant and skipper, Christen Pedersen, and Anna Olufsdatter Storm, daughter of an alderman.

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.

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 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.

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.

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

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.

But a realization that each group has much of substance to learn from the other also developed, and a strong conviction grew that each had insights and dimensions to contribute to ethically acceptable solutions of urgent political issues.

Together they also developed a new form of voltaic cell in which the wooden trough was replaced by one of copper, thereby producing stronger currents.

The relation between osmotic pressure and the Gibbs function may also be developed in an analogous way.

Mutants may also be developed with changes in biochemical properties that are of importance in identification.

In the more sophisticated atmosphere of today's developed nations, food-preservation techniques have sought also to bring variety, peak freshness, and optimum taste and flavor in foods at reasonable cost to the consumer.

We have also developed techniques for recognizing and locating underground nuclear tests through the waves in the ground which they generate.

Finally, we may also mention the several members of the self-consciously `` neoliberal '' movement that developed at the University of Chicago and is heavily indebted philosophically to the creative work of Alfred North Whitehead.

It is borne out also by the absence of any developed theory about how sin passes from one generation to the next.

Asteroids is also the first game to use Atari's " QuadraScan " vector-refresh system ; a full-color version known as " Color-QuadraScan " was later developed for games such as Space Duel and Tempest.

He also developed literary skills to write poetry in English.

Christie's stories are also known for their taut atmosphere and strong psychological suspense, developed from the deliberately slow pace of her prose.

Even though this period-known in its earlier part as the Spring and Autumn period and the Warring States period-in its latter part was fraught with chaos and bloody battles, it is also known as the Golden Age of Chinese philosophy because a broad range of thoughts and ideas were developed and discussed freely.

The parapsychologist H. H. Price had also developed his own hypothesis about what the afterlife may be like.

In doing so, he also developed the brightness scale still in use today.

The First Liberal government also established the basis of the later welfare state, with old age pensions, developed a system for settling industrial disputes, which was accepted by both employers and trade unions.

He also developed his own highly unusual theories of physics, according to which such concepts as " penetrability ", " suction and pressure " and " zig-zag-and-swirl " were discoveries on par with Einstein's Theory of Relativity.

He also developed, during the Great Depression, the populist economic theory of " Direct Credits ", according to which banks are the cause of all economic woe, the oppressors of both capital and labour.

Two of Ammonius's students-Origen the Pagan, and Longinus-seem to have held philosophical positions which were closer to Middle Platonism than Neoplatonism, which perhaps suggests that Ammonius's doctrines were also closer to those of Middle Platonism than the Neoplatonism developed by Plotinus ( see the Enneads ), but Plotinus does not seem to have thought that he was departing in any significant way from that of his master.

The Africa Alphabet ( also International African Alphabet or IAI alphabet ) was developed in 1928 under the lead of Diedrich Westermann.

Fleming also discovered very early that bacteria developed antibiotic resistance whenever too little penicillin was used or when it was used for too short a period.

An unofficial standard for spoken American English has also developed, as a result of mass media and geographic and social mobility, and broadly describes the English typically heard from network newscasters, commonly referred to as non-regional diction, although local newscasters tend toward more parochial forms of speech.

As a framework for his coherent duality theory he also introduced derived categories, which were further developed by Verdier.

AIX PS / 2 ( also known as AIX / 386 ) was developed by Locus Computing Corporation under contract to IBM.

In 1988, IBM announced AIX / 370, also developed by Locus Computing.

Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.
