Re: Stop using calories?

I believe that calorimetry is the science where you add caloric to
heat something and remove caloric to cool it. Caloric used to be
defined as an invisible weightless material that is found in all
matter but, as we all know, the entire concept of caloric was
disproved by Count Rumford in the 18th century. Some
scientists, and a large segment of the public, still cling to
this outmoded concept of adding or removing caloric.
However, knowing that there is no such thing as caloric, they
call the same invisible, weightless material HEAT or HEAT
ENERGY. Does changing the name change the concept?
