thermodynamics

One Internet, multiple worlds.  People have gone mobile, but iMechanica has not.  Although iMechanica is accessible from mobile phones, but it was not designed as such.  On the other hand, mobile social networks are good mostly for short forms.  A practical solution seems to be posting on iMechanica and linking the entries to social networks, such as twitter, wechat, and Facebook.  For example, The New Yorker has a strong presence on Facebook, as my sons and their friends would say.   

I'll be teaching an undergraduate course on engineering thermodynamics.  We will use the textbook by Cengel and Boles.  I will supplement the textbook using my own notes on thermodynamics.  Teaching this course will give me an opportunity to revise these notes and add new pieces. Here are notes for the opening lecture.

A single strand of polymer is a chain of a large number of monomers.  The monomers are joined by covalent bonds, and two bonded monomers may rotate relative to each other.  At a finite temperature, the polymer rapidly changes from one configuration to another.  When the two ends of the polymer are pulled by a force, the distance between the two ends changes.  The polymer is known as an entropic spring.

After many publications and lecture notes, Prof. Ian Murdoch has finally organized much of that material in the form of a book.

I am very hopeful that like Prof. Murdoch's lectures, this monograph will also help the readers to develop a better understanding of the physical aspects of mechanics. It will be a valuable addition to the researchers' personal collection.

I have divided the old notes on temperature into three parts:

• Principle of the conservation of energy
  
• Empirical observations of temperature (this part)
  
• Energy and fundamental postulate 
  

Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.

Notes and slides for a course on engineering thermodynamics.  I used the Dover edition of Carnot's book.
