### physical entity | variable:

Scalar
* are components of a force and nothing more
  - data that have discrete values
  - in fact zero rank tensors
  - numerical quantities that can be described with a single number
  - quantities having size only
  - single things
* can contain all types of data
  - strings, numbers, or references
  - have units, and perhaps an algebraic sign, but no direction
* have magnitude but no direction, such as time, mass, and temperature.

Social variable
* allow researchers to better understand the cause of a child's illness.
* are, for instance, socioeconomic or ethnic group, age or sex.
* reveal cultural differences and dictate the social norms of a society.

Physical entropy
* Entropies usually increase when a pure liquid or solid dissolves in a solvent.
* Entropy governs availability of energy for useful work
  - physical property
* More entropy means less energy available for doing work
  - more dispersal and degradation of energy

### physical entropy:

High entropy
* means low potential energy.
* refers to a state of great disorder.

Physical event
* are occasions for reflections
  - situations
  - to be thought of as movements according to law of material points in space
* play out upon an underlayment of interwoven fields of energy and matter.

### physical game:

Pro football
* is polyester and plastic and the salary cap.
* physical game.
* young game with many interlocking relationships.

### physical growth:

Biological growth
* is physical growth.
* occurs much more rapidly in seawater and in a warm location.
* provoke asthma or flu-like symptoms in many people.
* takes place when babies are born to church members.

### physical growth | biological growth:

Embryonic development
* Most embryonic development takes places.
* Some embryonic development occurs during pregnancy
  - in ovaries
* involves a blastula
  - cell division, differentiation, and morphogenesis
* is biological growth
  - disrupted both in vitamin A deficiency and in excess
* is, in the main, a continuous procedure, once fertilization has occurred.
* lasts approximately two weeks.
* occurs from the zygote through the eighth week of pregnancy
  - immediately
* requires the coordinated production and distribution of transcription factors.
* retraces the steps of evolutionary history.
* starts again when the temperature is increased
  - with fertilization to create a zygote

Physical malleability
* Malleability is also a quality of metals
  - dispositions
  - physical properties
* Malleability is the ability of a metal to be hammered into shapes
  - metal to be hammered into thin sheets
  - to be hammered out into sheets
  - extent to which a solid can be hammered or rolled into sheets. * ability of a metal to be hammered into thin sheets. Gold and silver are highly malleable. When a piece of hot iron is hammered it takes the shape of a sheet. It is not observed in non-metals. Aluminium foil is one example of a malleable metal. Non-malleable metals will break apart when struck by a hammer such as wood or tin

Physical matter
* adheres to the laws of classical physics, where matter is solid and predictable.
* is in a state of constant change.
