Thermodynamics

 The laws of thermodynamics are fundamental for understanding the  structure of matter and the transfer of heat. Remarkably they stand by themselves and have no need of any microscopic underpinning This point is often missed in treatments of thermodynamics which quickly move onto statistical physics and don't encourage physicists to develop their powers of thermodynamic reasoning. 

The best account of thermodynamics I know of is given in Longairs book 

https://www.amazon.co.uk/Theoretical-Concepts-Physics-Second-Alternative/dp/052152878X

Which then goes onto discuss how the attempts to model black body radiation broke down using classical physics thus paving the way for Planck and Einstein to introduce quantum mechanical ideas. It really is a fascinating story and shows that there is more to quantum mechanics than the development of Schrodinger's equation 

In general terms a good overall book on Thermodynamics is the classic by Zemansky

Anyway thermodynamics has many applications Chandresekhar used it to work out the General equations of stellar structure without any need to know the internal structure of a star 

Here is my tribute to Thermodynamics and I would encourage people to study it in it's own right 

                                 Thermodynamics

 

Three laws oh so neat,

Describing the nature of heat.

The first says you cannot win,

You wont get back more than you put in.

 

But if it’s heat, there’s a permanent loss,

That is only regained at greater cost.

Finally there will come a great big chill,

Where all that there is, will stand still.
