Introduction to Science

Definition of Science

• Systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Major Branches of Science

1. Natural Sciences

   • Focus on the study of natural phenomena.
   • Includes:
     • Physics: Study of matter, energy, and their interactions.
     • Chemistry: Study of substances, their properties, and reactions.
     • Biology: Study of living organisms and life processes.

2. Formal Sciences

   • Focus on abstract systems and structures.
   • Includes:
     • Mathematics: Study of numbers and their relationships.
     • Logic: Study of reasoning and argumentation.

3. Social Sciences

   • Study of societies and human behavior.
   • Includes:
     • Psychology: Study of mind and behavior.
     • Sociology: Study of social behavior and institutions.
     • Anthropology: Study of humans and cultures.

4. Applied Sciences

   • Use scientific knowledge to develop practical applications.
   • Includes:
     • Engineering: Application of science for design and construction.
     • Medicine: Application of health sciences for patient care.

Scientific Method

• A systematic approach to inquiry that involves:
  1. Observation: Gathering data and noting phenomena.
  2. Hypothesis: Formulating a testable explanation for observations.
  3. Experimentation: Testing the hypothesis through controlled experiments.
  4. Analysis: Interpreting results of experiments.
  5. Conclusion: Drawing conclusions from the analyzed data, which may support or refute the hypothesis.
  6. Reporting: Sharing findings with the scientific community for peer review.

Characteristics of Scientific Knowledge

• Empirical: Based on observed and measurable evidence.
• Rational: Applies logical reasoning to derive conclusions.
• Testable: Can be verified or falsified through experimentation.
• Reliable: Consistent and reproducible results across different conditions.
• Progressive: Science builds on existing knowledge and evolves over time.

Ethical Considerations in Science

• Integrity: Honesty in data collection and reporting.
• Transparency: Open sharing of methodologies and results.
• Accountability: Responsibility in conducting research ethically.
• Respect: Consideration for human and animal rights in research.

Importance of Science

• Drives technological advancements.
• Enhances understanding of the natural world.
• Informs policy and decision-making in society.
• Contributes to addressing global challenges (e.g., climate change, health crises).

Current Trends in Science

• Interdisciplinary research: Combining knowledge from various fields.
• Increased focus on sustainability and environmental science.
• Advancements in information technology and data analysis.
• Ethical considerations in genetic engineering and AI.
