In philosophy and psychology, awareness is the perception or knowledge of something. The concept is often synonymous with consciousness; however, one can be aware of something without being explicitly conscious of it (e.g., blindsight).
The states of awareness are also associated with the states of experience, so that the structure represented in awareness is mirrored in the structure of experience.
Observation in the natural sciences refers to the active acquisition of information from a primary source. It involves the act of noticing or perceiving phenomena and gathering data based on direct engagement with the subject of study.
In living organisms, observation typically occurs through the senses. In science, it often extends beyond unaided perception, involving the use of scientific instruments to detect, measure, and record data. This enables the observation of phenomena not accessible to human senses alone.
