Study Notes
Definition of Science
- Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Key Characteristics
- Empirical: Based on observation and experimentation.
- Hypothetical: Involves forming hypotheses that can be tested.
- Replicable: Experiments and results must be repeatable by others.
- Falsifiable: Must be able to be disproven by evidence.
Major Branches of Science
-
Natural Sciences
- Study of natural phenomena.
- Includes:
- Physics: Study of matter, energy, and the fundamental forces.
- Chemistry: Study of substances, their properties, and reactions.
- Biology: Study of living organisms and their interactions.
-
Social Sciences
- Study of human behavior and societies.
- Includes:
- Psychology: Study of the mind and behavior.
- Sociology: Study of social behavior and society.
- Economics: Study of the production, distribution, and consumption of goods and services.
-
Formal Sciences
- Study of abstract concepts and systems.
- Includes:
- Mathematics: Study of numbers, quantities, and shapes.
