Lord Kelvin and Absolute zero

Lord Kelvin, the Old Hatfield House and Absolute Zero As -273.16K.  First, who was Lord Kelvin? Second, what is absolute zero? Why the Old Hatfield House?

Absolute zero is named in degrees after Lord Lelvin
Lord Kelvin
  •  Absolute zero is the lower limit of the thermodynamic temperature scale. That is a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value. It is taken as zero. Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion. They retain only quantum mechanical, zero-point energy-induced particle motion. By international agreement, absolute zero is taken as −273.15° on the Celsius scale (International System of Units),[1][2 
  • William Thomson, 1st Baron KelvinOMGCVOPCFRSFRSE (/ˈkɛlvɪn/; 26 June 1824 – 17 December 1907) was a Scots-Irish[1][2] mathematical physicist and engineer  He was born in Belfast in 1824. Absolute temperatures are stated in units of kelvin in his honour. The existence of a lower limit to temperature (absolute zero) was known prior to his work, Lord Kelvin is widely known for determining its correct value as approximately −273.15 degree Celsius or −459.67 degree Fahrenheit.

Lord Kelvin has his name attached to the degree scale of absolute zero

Birthplace of Lord Kelvin was Glasgow, Ireland

Here is my thoughts about why the number -273.15K  is taken for absolute zero. In antiquity, Harmonia was the goddess associated with harmony. Harmony is based on comparative vibrations of two or more simultaneous tones. If molecules have a minimal vibrational motion at absolute zero, they cannot have harmony. Harmony is based on its number of  v/per sec:

  • Plato refers to the 272 as the number of harmony in his Canon Harmonia was the wife of Cadmus. Her name in Greek was spelled with the letters that added up to 272.
  • It is a masonic number. A rod of brickwork is 272 square feet.
  • The old Hatfield House in Hertfordshire, England  is 272 feet long.

Therefore the very next number (273)  is beyond harmony (272). It was chosen as the number of absolute zero.
