Precisely!
I strive to quantify it EVERY DAMN DAY!
However, you cannot with any sophisticated precision assign numerical parameters anywhere near what you might do with a mix of chemicals, a cube of titanium etc.
Saying you kissed her 24 times today; hugged her 18 times; carried out the trash 4 times; massaged her shoulders, neck & hands twice etc. is some numerical REPRESENTATION of your love for her. However, that description is NOT the SAME THING as your love. It is a rather detached, distant approximation guesstimate of a FEW of the parameters of your love for her.
Your micrometer or sub atomic analyzer will not work in measuring and quantifying love.
