His scale set the freezing point of water at 32 degrees and the boiling point at 212 degrees. This innovation marked a significant milestone in thermometry, enabling more accurate measurements across various fields. Around the same time, Swedish astronomer Anders Celsius was working on an alternative scale. In 1742, Celsius proposed a scale that set the freezing point of water at 100 degrees and the boiling point at 0 degrees. However, shortly after his death, French scientist Jean-Pierre Christin reversed this scale to what we now know as the Celsius scale: 0 degrees for freezing and 100 degrees for boiling. This change was formalized in 1750 by Carl Linnaeus, making the Celsius scale more intuitive and user-friendly. The 19th century saw further refinements with the introduction of absolute temperature scales. Lord Kelvin's work led to the development of the Kelvin scale, which is based on absolute zero (the theoretical temperature at which all molecular motion ceases) and is used extensively in scientific research.
