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 study of the natural world.
- Includes biology, chemistry, physics, earth science, and astronomy.
Formal Sciences
- Concerned with abstract concepts and logical systems.
- Includes mathematics, statistics, and computer science.
Social Sciences
- Study of human behavior and societies.
- Includes psychology, sociology, anthropology, and economics.
Applied Sciences
- Use of scientific knowledge for practical applications.
- Includes engineering, medicine, and technology.

Scientific Method

Observation
- Gathering data and noticing phenomena.
Question
- Formulating a question based on observations.
Hypothesis
- Proposing an explanation that can be tested.
Experimentation
- Conducting experiments to test the hypothesis.
Analysis
- Interpreting data collected during experimentation.
Conclusion
- Determining whether the hypothesis is supported or refuted.
Communication
- Sharing results with others to contribute to the body of scientific knowledge.

Key Concepts

Theory: Well-substantiated explanation of an aspect of the natural world, based on a body of evidence (e.g., theory of evolution, theory of relativity).
Law: Statement based on repeated experimental observations that describe some aspects of the universe (e.g., Newton's laws of motion).
Experiment: Controlled procedure to test a hypothesis.

Importance of Science

Enhances understanding of the natural world.
Drives technological advancement and innovation.
Informs public policy and decision-making.
Addresses global challenges (e.g., climate change, health).

Ethical Considerations

Importance of ethics in scientific research (e.g., integrity, responsibility, accountability).
Issues like consent, animal welfare, and environmental impact must be considered.

Current Trends in Science

Interdisciplinary research combining various scientific fields.
Increased emphasis on sustainability and environmental science.
Advancements in biotechnology and medicine.
The role of artificial intelligence in data analysis and research.
