This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.

Explains the second law of thermodynamics.

Outlines the seven main principles of energy.

Explains the differences between endothermic and exothermic reactions and the role thermodynamic potentials play in them. Examples from nature are also provided.

A variety of resources about Pynchon and his work are available from this site.

In this site you will find several topics from Physics such as materials, steam machines, conservation, the concept of entropy, relativity and gravitation,

The New Mexico Solar Energy Association provides an article entitled, "Electrolysis: obtaining hydrogen from water - the basis for a solar-hydrogen economy". The article is medium size in length with pictures and charts throughout to help.

This site from the Encyclopedia Wikipedia provides brief biographical information on German physicist and mathematician Rudolf Clausius including an image, hyperlinked terms, and external links.
