Anders Celsius By: Joshua Duvall
The Early Life • Born on November 27, 1701 in Ovanåker, Sweden • Died on April 25, 1744 in Uppsala, Sweden Influences • His grandfather Magnus Celsius the mathematician and Anders Spole the astronomer were both professors at Uppsala University. His father, Nils Celsius, was also professor in astronomy.
Education Through The Years • Celsius first started showing an aptitude for mathematics at the age of seven, therefore, his parents enrolled him into a math school. He aced every course and decided to got to college for Astronomy because of his and his grandfather’s love for the subject. • Celsius went to Uppsala University and studied astronomy. While in the university he showed excellent performance and when he was 29 he became a professor there.
Major Accomplishments • Invention of the Centigrade temperature system. • Accurate analysis of the Aurora Borealis using magnetic compasses. • Mapping of the Earth’s Torneå meridian to prove Newton’s theory that the Earth was an ellipsoid flattened at the poles.
What Do Those Things Mean To You? • Absolutely nothing. • The Centigrade scale is the world-wide accepted measurement for temperate in science. • Absolutely nothing. • It is also used by millions of people everyday around the world in almost every country except the US, Liberia, and Burma (or Myanmar). • Absolutely nothing. • Absolutely nothing. Green = Countries using metric system (Celsius scale) Black = Countries Using British Imperial System (Fahrenheit scale)
°F = Fahrenheit (British Imperial System) °R = Réaumur °C* = Celsius’s Original System °C = Revised Celsius Scale The Celsius Temperature Scale Celsius originally used 0 °C to equal boiling and 100 °C to represent freezing, but after he died, his lab assistant, Olof Hiorter, decided it would be better reversed and made 0 °C equal to the freezing point of water and 100 °C equal to the boiling point of water.
In Closing I believe that Anders Celsius is probably not in the top most important people in scientific history, but he has defiantly allowed the scientific community a simpler method of communication and measurement of scientific data. Allowing a scientist in London to understand the measurements of a scientist is say Botswana.
