Taxonomy of Forces:
Idea that velocity stays the same.
Bodies at rest tend to stay at rest.
A View of Life: Life is self-organizing, pervasive, and has been here a long time.
Lifes riddle: How can something persist even though the parts that make it up continually fall apart?
Concept of a processor:

Everything that is made up in matter exists in protons, neutrons, electrons are made in an arrangement
Some Chemistry: "Mad man science": You take two things with completely different properties, combine it, and it
makes something new. You rearrange it, a

A Closer Look At Reproduction:
Old definition of reproduction: Reproduction allows for persistence as long as

Principles of Biology
Vocabulary List - 2
ion - an atomic arrangement that has an unequal number of protons and electrons, hence as a whole bears a charge.
electron affinity - the pulling force that an atom has on another atom's electrons.
