Introduction to Science

Study Notes

Definition of Science

Systematic study of the natural world.
Based on observation, experimentation, and evidence-based conclusions.

Branches of Science

Natural Sciences
- Biology: Study of living organisms.
- Chemistry: Study of matter and its interactions.
- Physics: Study of matter, energy, and their interactions.
Formal Sciences
- Mathematics: Study of numbers, structures, and patterns.
- Logic: Study of reasoning and argument structure.
Social Sciences
- Psychology: Study of the mind and behavior.
- Sociology: Study of society and social behavior.
Applied Sciences
- Engineering: Application of scientific principles to design and build.
- Medicine: Application of biological sciences to health.

Scientific Method

Observation: Identify a phenomenon or problem.
Question: Pose questions based on observations.
Hypothesis: Formulate a testable explanation or prediction.
Experimentation: Design and conduct experiments to test hypotheses.
Analysis: Evaluate data and results.
Conclusion: Draw conclusions based on analysis.
Publication: Share findings for peer review and advancement of knowledge.

Key Concepts

Theory: A well-substantiated explanation of some aspect of the natural world.
Law: A statement based on repeated experimental observations that describes some aspect of the universe.
Peer Review: Process in which scientific work is evaluated by experts in the field before publication.

Importance of Science

Enhances understanding of the universe.
Drives technological advancements and innovation.
Informs public policy and health decisions.
Addresses societal challenges and environmental issues.

Challenges in Science

Reproducibility: Difficulty in replicating results.
Bias: Potential for personal or funding-related bias in research.
Ethical considerations: Issues surrounding testing and implications of scientific work.

Interdisciplinary Science

Combines insights from multiple scientific disciplines to solve complex problems (e.g., biochemistry, environmental science).
