Thermodynamics is the much abused slave of many masters - physicists who
love the totally impractical Carnot process, - mechanical engineers who
design power stations and refrigerators, - chemists who are successfully
synthesizing ammonia and are puzzled by photosynthesis, - meteorologists
who calculate cloud bases and predict föhn, boraccia and scirocco, -
physico-chemists who vulcanize rubber and build fuel cells, - chemical
engineers who rectify natural gas and distil f- mented potato juice, -
metallurgists who improve steels and harden surfaces, - - trition
counselors who recommend a proper intake of calories, - mechanics who
adjust heat exchangers, - architects who construe - and often
misconstrue - ch- neys, - biologists who marvel at the height of
trees, - air conditioning engineers who design saunas and the
ventilation of air plane cabins, - rocket engineers who create
supersonic flows, et cetera. Not all of these professional groups need
the full depth and breadth of ther- dynamics. For some it is enough to
consider a well-stirred tank, for others a s- tionary nozzle flow is
essential, and yet others are well-served with the partial d- ferential
equation of heat conduction. It is therefore natural that thermodynamics
is prone to mutilation; different group-specific meta-thermodynamics'
have emerged which serve the interest of the groups under most
circumstances and leave out aspects that are not often needed in their
fields.
