Introduction to Science and Its Branches

Study Notes

Definition of Science

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

Branches of Science

Natural Sciences
- Study of the universe and natural phenomena.
- Subdivisions include:
  - Physics: Matter, energy, and their interactions.
  - Chemistry: Composition, properties, and reactions of substances.
  - Biology: Study of living organisms.
  - Earth Science: Earth's structure, properties, processes, and components.
Formal Sciences
- Study of abstract concepts and logical reasoning.
- Includes disciplines like:
  - Mathematics: Abstract structure, patterns, and quantity.
  - Logic: Principles of valid reasoning and argumentation.
  - Computer Science: Study of algorithms, computation, and information systems.
Social Sciences
- Study of societies and human behavior.
- Examples include:
  - Psychology: Study of mind and behavior.
  - Sociology: Study of social behavior and structures.
  - Economics: Analysis of production, distribution, and consumption of goods.

Scientific Method

A systematic approach to inquiry.

Observation: Gather information about phenomena.
Question: Identify and formulate questions based on observations.
Hypothesis: Propose explanations for the observed phenomena.
Experimentation: Test the hypothesis through controlled experiments.
Analysis: Analyze data and draw conclusions.
Communication: Share results for peer review and further study.

Importance of Science

Advances technology and medicine.
Addresses global challenges (e.g., climate change, health crises).
Enhances understanding of the universe and human existence.

Ethical Considerations

Responsibility of scientists to conduct research ethically.
Issues include:
- Honesty and integrity in reporting results.
- Consideration of human and environmental impact.

Future Directions

Interdisciplinary research combining various fields.
Emphasis on sustainable practices and solutions.
Exploration of space and advancements in artificial intelligence.
