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 grandfathers
  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 Earths Torneå meridian to prove
  Newtons 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.

The Celsius Temperature Scale

• F Fahrenheit (British Imperial System)
• R Réaumur
• C Celsiuss Original System
• C Revised Celsius 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.
