Introduction to Science and its Branches

Definition of Science

• Systematic study of the natural world through observation and experimentation.
• Aims to understand, describe, and predict phenomena.

Branches of Science

1. Natural Sciences
   • Concerned with the physical world.
   • Subfields:
     • Physics (study of matter and energy)
     • Chemistry (study of substances and their interactions)
     • Biology (study of living organisms)
2. Formal Sciences
   • Deal with abstract concepts and logical reasoning.
   • Subfields:
     • Mathematics (study of numbers and shapes)
     • Logic (study of reasoning)
     • Computer Science (study of information processing)
3. Social Sciences
   • Study human behavior and societies.
   • Subfields:
     • Psychology (study of the mind and behavior)
     • Sociology (study of social behavior and structure)
     • Economics (study of production, distribution, and consumption)

Scientific Method

• A systematic approach to inquiry.

1. Observation: Gathering data through senses.
2. Question: Formulating questions based on observations.
3. Hypothesis: Proposing an explanation or prediction.
4. Experimentation: Testing the hypothesis through controlled experiments.
5. Analysis: Interpreting the data collected.
6. Conclusion: Deriving conclusions based on data analysis.
7. Replication: Testing results with repeated experiments.

Importance of Science

• Advances technology and medicine.
• Contributes to informed decision-making and policy.
• Enhances understanding of the environment and sustainability.
• Encourages critical thinking and problem-solving skills.

Key Concepts in Science

• Theory: Well-substantiated explanation of natural phenomena (e.g., theory of evolution).
• Law: Statement based on repeated experimental observations (e.g., Newton's laws of motion).
• Variable: Any factor that can be changed in an experiment (e.g., independent, dependent, controlled variables).

Current Trends in Science

• Interdisciplinary research (combining fields for innovative solutions).
• Emphasis on sustainability and environmental science.
• Advancements in technology (AI, biotechnology, space exploration).
• Ethical considerations in scientific research (biotechnology, AI ethics).
