Introduction to Science and Its Branches

Study Notes

Definition of Science

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

Branches of Science

Natural Sciences
- Focus on 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.
Social Sciences
- Study of societies and human behavior.
- Includes:
  - Psychology: Study of the mind and behavior.
  - Sociology: Study of social behavior and society.
  - Economics: Study of the production, distribution, and consumption of goods.
Formal Sciences
- Concerned with abstract concepts.
- Includes:
  - Mathematics: Study of numbers, quantities, shapes, and patterns.
  - Logic: Study of reasoning and argument structure.
  - Computer Science: Study of computation and information processing.

Scientific Method

Observation
- Gathering information through senses or instruments.
Question
- Formulating a question based on observations.
Hypothesis
- Proposing a testable explanation or prediction.
Experimentation
- Conducting tests to validate or refute the hypothesis.
Analysis
- Interpreting data collected during experiments.
Conclusion
- Drawing results and determining if the hypothesis is supported.
Repetition
- Repeating experiments to ensure reliability and validity.

Importance of Science

Advances knowledge and technology.
Provides solutions to practical problems.
Informs public policy and decision-making.
Fosters critical thinking and encourages skepticism.

Key Concepts

Theory vs. Law
- Theory: Broad explanation based on a body of evidence (e.g., Theory of Evolution).
- Law: Statement describing a consistent natural phenomenon (e.g., Law of Gravity).
Peer Review
- Process of evaluation by experts in the field to ensure quality and credibility of research.
Ethics in Science
- Ensuring integrity and ethical responsibility in research practices and reporting.

Current Trends in Science

Interdisciplinary research combining multiple fields.
Emphasis on sustainability and environmental science.
Advancements in technology (AI, genomics).
Importance of data science and big data analytics.
