Introduction to Science and Its Branches

Study Notes

Definition of Science

Systematic enterprise that builds and organizes knowledge.
Involves observation, experimentation, and theoretical explanation.

Branches of Science

Natural Sciences
- Study of natural phenomena.
- Includes:

  - Chemistry (study of substances and their reactions)
  - Biology (study of living organisms)
Formal Sciences
- Study of abstract concepts.
- Includes:
  - Mathematics (study of numbers and structures)
  - Logic (study of reasoning)
  - Computer Science (study of computation and algorithms)
Social Sciences
- Study of societies and human behavior.
- Includes:
  - Psychology (study of mind and behavior)
  - Sociology (study of social behavior)
  - Economics (study of production, distribution, and consumption of goods)
Applied Sciences
- Practical application of scientific knowledge.
- Examples:
  - Engineering (application of physics and materials science)
  - Medicine (application of biology and chemistry)

Scientific Method

A systematic approach to inquiry.
Steps include:
1. Observation
2. Question formulation
3. Hypothesis development
4. Experimentation
5. Data analysis
6. Conclusion
7. Peer review and publication

Importance of Science
