Introduction to Science

Study Notes

Definition of Science

Systematic study of the structure and behavior of the physical and natural world.
Based on observation and experimentation.

Branches of Science

Natural Sciences
- Focus on the natural world.
- Subdivisions:
  - Physics: Study of matter, energy, and interactions.
  - Chemistry: Study of substances, their properties, and reactions.
  - Biology: Study of living organisms and their processes.
Formal Sciences
- Abstract concepts and systems.
- Includes mathematics, statistics, and computer science.
Social Sciences
- Study of human behavior and societies.
- Includes psychology, sociology, and economics.
Applied Sciences
- Practical application of scientific knowledge.
- Examples: engineering, medicine.

Scientific Method

A systematic approach to investigation.

Observation: Gathering data through senses.
Question: Identifying a problem or query.
Hypothesis: Formulating a testable explanation.
Experimentation: Testing the hypothesis through experiments.
Analysis: Interpreting the data and results.
Conclusion: Determining if the hypothesis is supported or refuted.
Communication: Sharing findings with the scientific community.

Key Concepts in Science

Theory: A well-substantiated explanation of natural phenomena.
Law: A statement based on repeated experimental observations that describe some aspect of the world.
Data: Facts and statistics collected for analysis.
Variables: Factors that can change in an experiment (independent, dependent, controlled).

Importance of Science

Advances knowledge and understanding of the universe.
Drives technology and innovation.
Informs policy and decision-making.
Addresses global challenges (e.g., climate change, health crises).

Ethical Considerations

Importance of ethical standards in research.
Issues of consent, integrity, and transparency.
Impact of scientific advancements on society.

Interdisciplinary Nature

Collaboration between various scientific fields enhances understanding and innovation.
Examples: biochemistry (biology + chemistry), environmental science (biology + earth science).
