### fact | observation:

Astronomical observation
* Some astronomical observations use light.
* demonstrate that the universe began to exist.
* reveal a wealth of information about the universe.
* show that there is more matter in existence than has yet been seen.
* suggest zero or close to zero space-time curvature.

Careful observation
* basic skill in social research.
* can help define the type of obesity.
* indicate patterns.
* is an important skill in science
  - the best way to determine a plant's water needs

Clinical observation
* determine decisions about individuals.
* is the precursor of experimentation.

### fact | observation:

Direct observation
* counts more in courts of law than in social science.
* is the ideal method for visualizing developing embryos
  - when behavior is watched and recorded
+ Applied behavior analysis, Analyzing Behavior, Data collection
  * There are different ways that behavior analysts collect data about a behavior. First, they use direct observation. Direct observation is when behavior is watched and recorded. In ABA, direct observation is used with naturalistic observation a lot. Unobtrusive measures in behavioral assessment. Naturalistic observation means the behavior is studied in its natural environment. So the behavior is observed in the place it normally happens.

Field observation
* lead to estimations.
* show aspects
  - regeneration

Infrared observation
* explore the hidden Universe.
* indicate that stars near the center of our galaxy are packed close together.
* look at colors, or wavelengths, beyond the range of human vision.
* reach back to the early life of the cosmos.
* show that a ring of intense star formation surrounds the nucleus
  - the cool state of matter
