Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Negentropy?Quantifying information content and understanding the organization of living systems
2. What is the theoretical basis?Developed from thermodynamics and information theory, notably by Brillouin and Schrödinger
3. What is the related scientific law?The second law of thermodynamics (entropy tends to increase)
4. What is negentropy and how is it different from entropy?Negentropy measures how organized a system is. It is the opposite of entropy, which measures disorder. When negentropy is high, the system has a lot of order and structure.
5. Why do living things need negentropy to stay organized?Living things use energy and information from their surroundings to keep their bodies and cells organized. This helps them stay alive and work properly.

Entropy: A thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work; measure of disorder.
Negentropy: A measure of the degree of order, organization, and structure within a system; the opposite of entropy.
Dissipative Structures: Complex systems that maintain order far from equilibrium by exchanging energy and matter with their environment.
