Introduction to Science

Study Notes

Definition of Science

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

Main Branches of Science

Natural Sciences: Study of the natural world.
- Example fields: Physics, Chemistry, Biology.
Formal Sciences: Study of abstract concepts.
- Example fields: Mathematics, Logic, Statistics.
Social Sciences: Study of societies and human behavior.
- Example fields: Psychology, Sociology, Anthropology.
Applied Sciences: Practical application of scientific knowledge.
- Example fields: Engineering, Health Sciences, Environmental Science.

Scientific Method

Observation: Gathering data through senses or instruments.
Question: Formulating questions based on observations.
Hypothesis: Proposing a testable explanation.
Experimentation: Testing the hypothesis through controlled experiments.
Analysis: Interpreting the data collected from experiments.
Conclusion: Drawing conclusions based on analysis; can support or refute the hypothesis.
Communication: Sharing results with the scientific community.

Key Concepts

Theory: A well-substantiated explanation of some aspect of the natural world.
Law: A statement based on repeated experimental observations that describe some aspects of the universe.
Variables: Factors that can change in an experiment (independent, dependent, and controlled).
Peer Review: Process by which a scientific work is evaluated by a group of experts before publication.

Importance of Science

Advances understanding of the universe.
Informs evidence-based decision-making.
Drives technological innovation.
Addresses global challenges (e.g., climate change, health crises).

Ethical Considerations

Responsible conduct in research.
Ethical treatment of human and animal subjects.
Consideration of environmental impacts.

Challenges in Science

Reproducibility crisis: Difficulty in replicating research results.
Science communication: Effectively conveying scientific knowledge to the public.
Misinformation: Combatting false claims and pseudoscience.
