Anders Celsius independent of latitude (and of atmospheric pressure). He determined the dependence of the boiling of water with atmospheric pressure which was accurate even by modern-day standards. He further gave a rule for the determination of the boiling point if the barometric pressure deviates from a certain standard pressure. He proposed the Celsius temperature scale in a paper to the Royal Society of Sciences in Uppsala, the oldest Swedish scientific society, founded in 1710. His thermometer was calibrated with a value of 100° for the freezing point of water and 0° for the boiling point. In 1745, a year after Celsius'
Anders Sørensen Vedel Anders Sørensen Vedel Anders Sørensen Vedel (9 November 1542 – 13 February 1616) was a Danish priest and historian. He translated the "Gesta Danorum" by Saxo Grammaticus into Danish in 1575, and published the influential ""Hundredvisebogen"" in 1591. Anders Sørensen was born in Vejle, from which place the Vedel name comes. 14 years old he moved to study in Ribe, and after finishing his education he moved on to Copenhagen University in 1561. In 1562, he was the tutor of astronomer Tycho Brahe on Brahe's Grand Tour in Europe, forming a lasting bond of friendship with him. Vedel started studying
