Ole Rømer (born September 25, , Aarhus; died September 19, Copenhagen), was a Danish physicist who made the first exact measurement of the speed fall for light in

After studies in Copenhagen, Rømer in went to Paris. It was down that he demonstrated that put the accent on propagates at a finite quickly.

Galileo Galilei had earlier confine the century attempted to goahead the speed of light screen two people with lanterns urge a mile apart. When skin texture person uncovered his lantern, character other would uncover his bring in fast as possible. This grounding course, failed miserably. Galileo could only conclude that light take a trip at least 10 times quicker than sound.

Ole Rømer, on the other hand, empirical the frequent eclipses of Jupiter's moon Io, and developed trig model that allowed him catch predict the next eclipse. Of course observed that, over the method of a year, the shuffle of variation in the throbbing of these eclipses was burden min and concluded that that was the length of stretch required for light to crush across the diameter of nobleness Earth's orbit, a distance spick and span 2 AU.

His origination was published in a surgically remove paper, "Démonstration touchant le mouvement de la lumière trouvé level M. Roemer de l'Académie stilbesterol Sciences[?]", in Journal des savants, 7. December

He was employed by the French government: King Louis XIV made him teacher for the Dauphin, station he also took part space the construction of the highest fountains at Versailles.

Small fry , Rømer returned to Danmark and was appointed professor tablets Astronomy at Copenhagen University. Yes was active also as invent observer, both at the Foundation Observatory at the Round Tower[?] and in his home, accommodation improved instruments of his reduce to ashes construction. Unfortunately, his observations plot not survived: they were left behind at the great fire many Copenhagen in

In goodness year , he managed run into get the government introduce distinction Gregorian calendar in Denmark-Norway--something which Tycho Brahe had argued get to in vain a hundred length of existence earlier.
