Amplification Triad

A signal is *amplified* when it is strengthened by the application of energy. Humans often amplify electrical and electronic signals for various reasons. Sound and light signals are some signals in nature often amplified by humans. The concept of *amplification* is ubiquitious in Nature. In fact *growth* is *amplification*.

(a) A seed is planted and eventually grows into a tree. Identify the components of the *amplification-triad* for the *planting*: the *signal*, the *applied energy* and the *amplified signal*.

(b) A nation is founded and eventually grows into a great nation. Identify the components of the *amplification-triad* for the *nation*: the *signal*, the *applied energy* and the *amplified signal*.

**The strings**:
S_{7}P_{5}A_{51} (Physical Change).
**The math**:

Pj Problem of Interest is of type *change* (physical change). There are also many instances of amplifications that are chemical changes.

The broad *amplification context* presented here is based on the following broad definition of *signals*: a *signal* is any entity in space to which a *meaning* has been *mapped*. In other words, if it exists in space and has *meaning*, it is a *signal*. For example, a name is a *signal* and the individual to whom the name has been assigned is also a *signal*.

(a) The seed is the *signal*. Water and fertile soil are the initial *energy* applied. Additional energy (sunlight, carbon dioxide, chlorophyll). The various states of growth represent various states of *amplified signals*.

(b) the nation is the *signal*. The human energy (spiritual, intellectual and physical) of the inhabitants of the nation and its resources represent the *applied energy*. The various states of the nation's growth represent various states of *amplified signals*.

Math

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of *matter* and *radiant energy*. *Matter* is any kind of *mass-energy* that moves with velocities less than the velocity of light. *Radiant energy* is any kind of *mass-energy* that moves with the velocity of light.
