Anders Celsius
Definition
Anders Celsius was a Swedish astronomer and physicist who is best known for developing the Celsius temperature scale. He was born in Uppsala, Sweden, in 1701. He studied astronomy and mathematics at the University of Uppsala, where he later became a professor.
In 1742, Celsius proposed a new temperature scale that was based on the freezing and boiling points of water. The scale was originally called the centigrade scale, and it was divided into 100 degrees. The freezing point of water was 0 degrees, and the boiling point was 100 degrees.
The Celsius scale was later renamed after Celsius, and it is now the most widely used temperature scale in the world.
Celsius also made contributions to the fields of astronomy and physics. He developed a method for measuring the temperature of stars, and he also studied the aurora borealis.
Celsius died in Uppsala in 1744. He is considered one of the most important scientists of the 18th century.

Different forms of the word
Anders Celsius is a proper noun.
Etymology
The name "Anders Celsius" is of Swedish origin. The given name "Anders" is of Germanic origin and means "manly". The surname "Celsius" is a latinisation of the Swedish word "Celsi", which means "of Celsius".
The name "Anders Celsius" is, therefore, a combination of two words that both have positive connotations. This is perhaps a fitting name for someone who was such a brilliant and influential scientist.

AQA Science Exam Question and Answer
Question:
Who was Anders Celsius, and what is his notable contribution to the measurement of temperature?
Answer:
- Anders Celsius was a Swedish astronomer and physicist. He is renowned for developing the Celsius temperature scale, where 0°C represents the freezing point of water and 100°C represents its boiling point at standard atmospheric pressure. This Celsius scale, also known as the centigrade scale, is widely used for temperature measurement in most parts of the world.
