Another original result of his is the Thomson formula for super-saturation in the processes of boiling and condensation on account of surface energy. However here I choose to highlight Kelvin s capacity for original thought by a proposition he made for an absolute temperature . - an alternative to the Kelvin scale which we all know see Insert .
