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.

Key Branches of Science

Natural Sciences
- Focus on the nature and characteristics of the physical world.
- Includes:
  - Physics: Study of matter, energy, and their interactions.
  - Chemistry: Study of substances, their properties, and reactions.
  - Biology: Study of living organisms and their interactions.
Formal Sciences
- Concerned with abstract concepts and logical reasoning.
- Includes:
  - Mathematics: Study of numbers, quantities, shapes, and patterns.
  - Statistics: Study of data collection, analysis, interpretation, and presentation.
  - Logic: Study of valid reasoning and argumentation.
Social Sciences
- Study of individuals and societies.
- Includes:
  - Psychology: Study of mind and behavior.
  - Sociology: Study of social behavior and society.
  - Anthropology: Study of humans, their behavior, and cultures.

Scientific Method

Observation
- Gathering data through senses or instruments.
Hypothesis
- Formulating a testable prediction based on observations.
Experimentation
- Conducting tests to validate or refute the hypothesis.
Analysis
- Interpreting data gathered from experiments.
Conclusion
- Drawing conclusions based on the analysis and determining if the hypothesis is supported.
Replication
- Repeating studies to verify results.

Important Concepts

Theory: A well-substantiated explanation of some aspect of the natural world, based on a body of evidence.
Law: A statement that describes an observable phenomenon, often expressed mathematically.
Peer Review: Process by which research is evaluated by other experts in the field before publication.

Role of Science in Society

Advances technology and medicine.
Informs public policy and environmental protection.
Enhances our understanding of the universe and promotes critical thinking.

Ethical Considerations

Importance of ethical standards in conducting research.
Issues like consent, confidentiality, and the potential for harmful consequences.

Current Trends in Science

Interdisciplinary research (e.g., bioinformatics, environmental science).
Growth of data science and artificial intelligence.
Focus on sustainable practices and renewable energy.
