Definition and Branches of Science

Definition of Science

• Systematic enterprise that builds and organizes knowledge.
• Utilizes empirical evidence from observations and experiments.

Branches of Science

1. Natural Sciences

   • Study of natural phenomena. Divided into:
     • Physics: Study of matter, energy, and their interactions.
     • Chemistry: Study of substances, their properties, and reactions.
     • Biology: Study of living organisms and life processes.
     • Earth Science: Study of the Earth, its atmosphere, and ecosystems.

2. Formal Sciences

   • Study of abstract structures and concepts. Includes:
     • Mathematics: Study of numbers, quantities, and shapes.
     • Logic: Study of reasoning and argument.
     • Statistics: Study of data collection, analysis, and interpretation.

3. Social Sciences

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

Scientific Method

• A systematic approach to inquiry. Steps include:
  1. Observation: Identifying a phenomenon.
  2. Question: Formulating a question based on observation.
  3. Hypothesis: Proposing an explanation to test.
  4. Experimentation: Conducting tests to support or refute the hypothesis.
  5. Analysis: Interpreting the data gathered from experiments.
  6. Conclusion: Drawing conclusions based on the analysis.
  7. Reporting: Sharing results for peer review and further investigation.

Importance of Science

• Enhances understanding of the natural world.
• Drives technological advancements.
• Informs public policy and health recommendations.
• Fosters critical thinking and problem-solving skills.

Key Concepts

• Theory: Well-substantiated explanation of an aspect of the natural world.
• Law: Statement based on repeated experimental observations that describes some aspect of the universe.
• Hypothesis: Testable proposition explaining a phenomenon.

Scientific Research

• Peer-reviewed to validate findings.
• Often funded by governments, educational institutions, and private organizations.
• Ethical considerations are paramount, especially in human and animal studies.

Emerging Fields

• Biotech: Combining biology and technology for medical advances.
• Environmental Science: Study of interactions within the environment.
• Astrobiology: Search for life beyond Earth.

Challenges in Science

• Misinformation and pseudoscience.
• Ethical dilemmas in research.
• Funding responses and economic impacts.
• Climate change and sustainability issues.
