Introduction to Science

Study Notes

Definition of Science

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

Key Characteristics

Empirical: Relies on observable and measurable evidence.
Repeatable: Experiments must yield consistent results when repeated.
Falsifiable: Hypotheses must be testable and potentially disprovable.
Objective: Aims to minimize bias and subjective interpretation.

Major Branches of Science

- Physics: Study of matter, energy, and fundamental forces.
- Chemistry: Study of substances, their properties, and reactions.
- Biology: Study of living organisms and life processes.
Formal Sciences: Study of abstract concepts.
- Mathematics: Study of numbers, quantities, and shapes.
- Logic: Study of reasoning and argumentation.
Social Sciences: Study of human behavior and societies.
- Psychology: Study of the mind and behavior.
- Sociology: Study of social behavior and institutions.
- Economics: Study of production, consumption, and distribution of goods.
Applied Sciences: Practical application of scientific knowledge.
- Engineering: Application of physical and mathematical principles.
- Medicine: Application of biological sciences to health care.

Scientific Method

Observation: Identify a phenomenon.
Question: Formulate a question about the observation.
Hypothesis: Propose a testable explanation.
Experimentation: Design and conduct experiments to test the hypothesis.
Analysis: Analyze data to determine if the hypothesis is supported.
Conclusion: Draw conclusions; may lead to new questions and further research.

Importance of Science
