Information theory
* Information theories are scientific theories.
* Some information theories apply to patterns.
* describes the information content of a sequence of symbols.
* extends across a broad field of sciences and disciplines.
* forms a mathematical basis for equilibrium statistical mechanics.
* gives fundamental limits on schemes of data compression, coding, modulation, etc.
* is applied to derive constraint weights on a probabilistic basis
  - of a more theoretical nature than data compression
  - particularly relevant in several areas of molecular biology
  - regarded as the foundation of statistical mechanics
* is used to select the attributes to ask for
  - substantiate the necessity of external design
* offers a way to quantify the amount of information.
* recognises that all data are inexact and statistical in nature.
* talks about the notion of information.
* touches many topics and it rewarding place in which to spend one's life.
+ Theoretical computer science
  * Information theory talks about the notion of information. Originally it was developed for signal processing. It is concerned with how a message needs to be changed, so that it can be transmitted over a  channel, an how to undo the changes at the other end, so that the original message can be recovered. These processes are known as encoding and decoding. Information theory also talks about how much self-information there is in a message. This is the theoretical basis for data compression, cryptography and digital signatures.

Organicism
* implies concomitant states of being and becoming, of statis and evolution
  - movement
  - the pursuit of wisdom
* scientific theory

Relativity theory
* clarifies the distinction between relative and absolute.
* prohibits travel or communication faster than light.
* says there can be more than one right answer for the speed and mass of an object.
* spacializes time.
* takes the view that the only possible absolute is the velocity of light.

Screw theory
* allows for compact notation of the equations of motion and kinematics.
* is introduced to describe gripper performance.

Several theory
* Several theories attempt to explain what causes the abnormal growth of prostate tissue cells
  - why our joints deteriorate
  - do exist, explaining how Earth's gravity has been able to change
* Several theories exist about what causes gamma-ray bursts
  - as to how endometriosis begins
  - to explain the link between periodontal disease and heart disease
  - point to sleep as a state vital to memory and learning
  - propose that the immune system turns on itself

### theory:

Social theory
* Social theories are explanations offered to account for a set of social phenomena.
* deals with human values.
* focuses upon the causal importance of the individual and society.
* goes beyond ad hoc concepts and develops systems of concepts to explain phenomena.
* is among the most challenging and rewarding pursuits among all human endeavors
  - analysis of humans and their societies
  - essential for any meaningful analysis of the complexities of everyday life
  - the core of sociology
  - what people do when they try to figure out how the social world works
* means norms, social emphasis.

Socialist theory
* holds that the state is to be the agent of collective redistribution.
* is essential to understand the world in order to change it.
