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.
