Science Talks: Cell Components and the Second Law of Thermodynamics Make Us Reflect on the Greatness of Science

 Cell components and the Second Law of Thermodynamics makes a person think that science is great. If we were to take a living cell apart into its basic components/structures and lay them in the sunlight, what would happen?

The answer is more decay. Even though the parts would be in an open system and have a source of energy (the sun), the parts would not assemble (become more complex) into a living cell because they do not contain functional mechanisms (the parts must be assembled into an integrated functional system). Adding energy (sunlight) to an open system is not sufficient to overcome the second law. All four mechanisms must be in existence and functional (an open system, a source of energy, a mechanism to capture energy and a mechanism to convert energy into useful energy for doing work).

Where did the Organization and Complexity Come from? Working backwards, the second law clearly points to a beginning. In fact, it points noy only to a beginning, but also to a highly organized and complex beginning. This raises the question: If the universe is becoming less organized, where did the initial organization and complexity originate?

Summary of the Second Law can be stated in many different ways. Here is a list the many ways:

1) A measure of disorder

2) Usable energy is running out

3) Information tends to get scrambled

4) Order tends towards disorder

5) A random jumble will not organize itself

Evolution contradicts or violates the Second Law of Thermodynamics It does not matter whether the system is open or isolated; everything is decaying over time.

The Second Law of Thermodynamics tells us the universe must have had a beginning and that it must have been highly organized.

The First Law of Thermodynamics tells us that the universe could not have created itself.
