Thermodynamics

The book I read to research this post was Thermodynamics for Dummies by Mike Pauken which is an excellent book which I bought from kindle. This book takes a very complex subject & makes it reasonably easy to understand. Thermodynamics comes from 2 ancient greek words thermo means heat & dynamic means movement. There are 2 laws you must understand. The 1st is you can neither create or destroy energy it merely travels from one form to another. The 2nd is energy flows from a high concentration to a low concentration until equilibrium is acheived. The steam engine was mans 1st means of harnessing thermodynamics but the same principles can even be applied to a nuclear power station. 1st you have the pump which delivers the fuel. Then it's heated, then it drives a turbine & then it's cooled in a condenser by cold water. Admittedly in a nuclear power station it's not heated. Terms like celsius are often named after famous people. Fahrenheit was constructed by 0 being the freezing point of salt water & 100 being what he thought was the temperature of the human body in fact it's 96.
