Musings on the second law and life. (December 2002) (PDF file, 60K)
Some thoughts inspired by discussion with the author of the New Scientist article about our work.

• Why I think exergy is more appropriate than entropy for discussing self-organization and living systems.
• New insights derived from the restated second law, particularly with respect to the emergence of life.
