Introduction to Science Definitions

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

   • 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.

3. Formal Sciences

   • Study of abstract concepts and systems.
   • Includes:
     • Mathematics: Study of numbers, quantities, and shapes.
     • Logic: Study of reasoning and argumentation.

4. Applied Sciences
