Introduction to Science and Its Branches

Definition of Science

• Systematic study of the natural world.
• Involves observation, experimentation, and analysis.

Branches of Science

1. Natural Sciences

   • Focus on the physical world.
   • Subdivisions:
     • Physics: Study of matter and energy.
     • Chemistry: Study of substances and their properties.
     • Biology: Study of living organisms.

2. Social Sciences

   • Study of human behavior and societies.
   • Subdivisions:
     • Psychology: Study of the mind and behavior.
     • Sociology: Study of social behavior and structures.
     • Economics: Study of production, distribution, and consumption of goods.

3. Formal Sciences

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

4. Applied Sciences

   • Practical application of scientific knowledge.
   • Examples include engineering, medicine, and technology.

Scientific Method

1. Observation: Gathering data through the senses.
2. Hypothesis: Formulating a testable statement based on observations.
3. Experimentation: Conducting experiments to test the hypothesis.
4. Analysis: Interpreting the data collected from experiments.
5. Conclusion: Drawing conclusions based on the analysis.
6. Replication: Repeating experiments to verify results.

Importance of Science

• Enhances understanding of the universe.
• Drives technological advancements and innovations.
• Informs public policy and decisions.
• Provides solutions to societal challenges.

Key Concepts

• Theory: Well-substantiated explanation of some aspect of the natural world.
• Law: Statement based on repeated experimental observations that describe an aspect of the world.
• Peer Review: Process where scientific work is evaluated by experts before publication.

Ethical Considerations

• Importance of integrity in research.
• Ethical treatment of subjects (human and animal).
• Responsible communication of findings.
